NUMBER OF 
SITES / TRIAL 
LOCATION
Approximately two sites in Spain are expected to participate in this 
study.
STUDY
OBJECTIVES 
Primary:

To assess the effect of itraconazole on lurbinectedin total plasma 
exposure in patients with advanced solid tumors. 
Secondary:

To assess the effect of itraconazole on lurbinectedin unbound 
plasma exposure.

To assess the effect of itraconazole on lurbinectedin major 
metabolites (i.e., M1 and M4).

To assess the effect of itraconazole on the safety profile of 
lurbinectedin.

To collect and store a blood sample for germline DNA 
extraction for future pharmacogenetic (PGt) analysis of 
variations on genes that may influence exposure and response 
(i.e., disposition, metabolism and safety) to lurbinectedin.
STUDY DESIGN
Prospective, open-label, two-way crossover, phase Ib drug-drug 
interaction study in patients with advanced solid tumors.
The study will include a pre-treatment (screening) phase followed 
by a treatment phase consisting of two lurbinectedin cycles, one 
cycle in combination with itraconazole and one cycle as single agent 
(in different order depending on the study sequence), and one 
additional third cycle of lurbinectedin as a single agent for patients 
who meet the continuation criteria and obtain a clinical benefit after 
the first two cycles, and then follow-up of adverse events if any.
Patients who meet the continuation criteria and obtain a clinical 
benefit after the first two cycles according to the Investigator’s 
criteria will have the opportunity to continue treatment under a 
Compassionate Use Agreement after the completion of the optional 
third study cycle.
Patients will be treated as outpatients. At the discretion of the 
Investigator, patients may be admitted to the study center on Day –1 
or Day 1 and monitored, at least, until completion of the Day 1 
pharmacokinetic
(PK)
blood 
sample 
collections.
Patients will receive a maximum of three cycles: two consecutive 
cycles of lurbinectedin, one cycle with and one cycle without 
itraconazole co-administration (in different order depending on the 
study Sequence 1 or Sequence 2 of treatment), followed by a third 
cycle with lurbinectedin alone (this last optional for patients with 
clinical benefit). Lurbinectedin will be administered as a 1-hour (-

5/+20 min) intravenous (i.v.) infusion every three weeks (q3wk) via 
a central or peripheral vein. This study will consist of two parts
(Figure S1): Part A and B. The dose of lurbinectedin when given in 
combination with itraconazole for the initial three patients in Part A 
will be 0.8 mg/m², and in Part B is susceptible to be adjusted 
properly if deemed necessary based on exposure and safety 
experience in Part A. The dose of lurbinectedin during Parts A and 
B will be 3.2 mg/m² for all patients when administered without 
itraconazole. If toxicity occurs, the appropriate intra-patient dose
level (DL) reductions will be implemented in the subsequent cycle. 
This DL reduction will be according to Table S3.

based on exposure and safety experience in Part A.
ITZ, itraconazole; LRB, lurbinectedin; TR, test-reference; R; randomized; RT, 
reference-test.
In Part A, three patients will be enrolled to Sequence 1 (TR: Test-
Reference) and will receive itraconazole with lurbinectedin in Cycle 
1 followed by two consecutive cycles of lurbinectedin alone (the 
last cycle being optional for patients with clinical benefit according 
to the Investigator’s criteria). Enrollment for Part A will be 
sequential. Once the first patient enrolled has completed Cycle 1 
and Cycle 2, the second and the third patients could be enrolled 
simultaneously, after the evaluation of lurbinectedin total PK 
parameters, and if no unacceptable or life-threatening toxicities 
have occurred for this first patient. However, if toxicity occurs, the 
appropriate dose reductions will be implemented with the second 
and third patients based on the PK and safety information of first 
patient. 
The dose of lurbinectedin when given in combination with 
itraconazole for the initial three patients in Part A will be 0.8 
mg/m². However, if lurbinectedin exposure in the first patient of 
Part A does not allow an adequate PK assessment, the lurbinectedin 
dose of the following patients may be increased accordingly.
Upon exposure and safety assessments in Part A, the dose of 
lurbinectedin to be co-administered with itraconazole in Part B can 
be readjusted accordingly. This decision will be made by the 
Sponsor and the study Investigators. Therefore, the planned dose of 
lurbinectedin, when given with itraconazole for the remaining eight 
patients in Part B, will be based on the acceptability of the PK and 
safety results from the first three patients in Part A. If the initial 
three patients in Part A do not experience adverse events (AEs) 
which might require a dose-reduction, the dose of lurbinectedin may 
still be adjusted (based on the assumption of dose-proportional 
pharmacokinetics) to produce plasma lurbinectedin area under the 

CL_0363 3.0

Protocol PM1183-A-018-20
curve (AUC) values that are comparable to those when 
lurbinectedin is given in the absence of itraconazole. However, if 
toxicity occurs in the initial three patients in Part A, the appropriate 
dose-reduction of lurbinectedin will be implemented in Part B 
accordingly.
If the safety and PK data obtained from the three patients in Part A 
(at least from Cycle 1) is deemed acceptable, as defined in the study 
protocol, Part B of this study will begin enrollment. Therefore, once
Part A is completed, patients in Part B will be enrolled based on the
review of the safety following completion of the first cycle of the 
previous patient(s), and will be randomized in a 1:1 ratio to 
Sequence 1 (as used in Part A) or Sequence 2 (RT: Reference-Test; 
lurbinectedin + itraconazole in Cycle 2).
Patients will receive lurbinectedin until disease progression, 
unacceptable toxicity, consent withdrawal or while it is considered 
to be in their best interest, and for a maximum of three cycles.
Treatment with lurbinectedin outside this study could be continued 
under a Compassionate Use Agreement after the completion of the 
optional third study cycle.

lurbinectedin infusion), and supplied at the study center on Day 1,
following 
recommendations 
at 
the 
Summary 
of 
Product 
Characteristics (SmPC). On Day 1 (i.e., day of lurbinectedin 
infusion), itraconazole will be given immediately prior to the start of 
the lurbinectedin infusion.
In fact, itraconazole should be 
administered after obtaining the itraconazole pharmacokinetic (PK)
sample #1 and before the start of lurbinectedin infusion (-15 min to -
1 min).
In case of lurbinectedin delay (≤2 days), itraconazole could be 
administered during a maximum of 14 days.
Part A:
All patients will receive itraconazole plus lurbinectedin in Cycle 1 
and lurbinectedin alone in Cycles 2 and 3 (this last cycle being 
optional for patients with clinical benefit).
Part B:
Patients will be randomly assigned to the corresponding sequences:
Sequence 1 (TR) (same used in Part A):

Cycle 1: Itraconazole + lurbinectedin

Cycle 2: Lurbinectedin alone

Cycle 3: Lurbinectedin alone (optional)
Sequence 2 (RT):

Cycle 1: Lurbinectedin alone

Cycle 2: Itraconazole + lurbinectedin

Cycle 3: Lurbinectedin alone (optional)
DOSE
Itraconazole co-administration cycle:

Itraconazole: 200 mg (two capsules of 100 mg) orally (p.o.) 
once daily.

Lurbinectedin: 0.8 mg/m² as a 1-hour (-5/+20 min) i.v. infusion 
on Day 1 on Part A. Dose on Part B will depend on PK and 
safety outcomes in Part A.
Single agent lurbinectedin cycle:
3.2 mg/m² as a 1-hour (-5/+20 min) i.v. infusion on Day 1. 
PROPHYLACTIC
MEDICATION
All patients, will receive standard antiemetic prophylaxis before each 
treatment infusion (i.e., 30 ± 5 minutes before lurbinectedin 
administration), i.v. as follows:

Corticosteroids 
i.v. 
(according 
to 
institutional 
standard 
antiemetic doses, at least dexamethasone i.v. 8 mg, or 
equivalent, maximum 20 mg/day of dexamethasone or 
equivalent). If feasible, the medication and dose administered in 
Cycle 1 should be maintained in Cycle 2.

Serotonin (5-HT3) antagonists (ondansetron at least 8 mg i.v. 
and no more than 16 mg of ondansetron).
If necessary, in addition to the above, the duration of treatment with 
5-HT3 antagonists and/or dexamethasone could be extended orally (if 
needed) (i.e., 4-8 mg/day for three consecutive days) and/or 10 mg of 
metoclopramide orally every eight hours could be added.
Aprepitant or any other NK-1 antagonist or related Substance P-
antagonists (except for rolapitant) are forbidden while on

study medication and until 31 days after the last administration 
of lurbinectedin, unless the Investigators, with the Sponsor 
agreement, consider it will not interfere with study procedures 
of patient safety. 
DRUG-DRUG 
INTERACTIONS
In vitro studies with human microsomes have shown that CYP3A4 
is the major CYP isoform involved in the metabolism of 
lurbinectedin. The estimated contribution of the other CYP 
isoenzymes to the lurbinectedin metabolism is considered to be 
negligible. Therefore, concomitant drugs which induce or inhibit 
any of these cytochromes, especially CYP3A4, should be carefully 
monitored or avoided, whenever is possible.
A potentially significant interaction with aprepitant is suggested by 
available phase II data from ovarian cancer patients and phase I data 
from the PM1183-A-008-13 study. Lurbinectedin clearance was 

CL_0363 3.0
Page 15 of 93
Protocol PM1183-A-018-20
reduced by around 30%, approximately, in the presence of 
aprepitant. Although all patients eventually recovered, the use of 
aprepitant is currently forbidden in all phase II/III lurbinectedin
studies.
EVALUABILITY 
OF PATIENTS
Part A: An evaluable patient for Part A should have completed 
sufficient study procedures until Day 8 of Cycle 1 (i.e., most 
itraconazole administration and PK assessments).
Part B: An evaluable patient for the main objective of the study 
(e.g., assessment of lurbinectedin PK) should have provided 
sufficient and interpretable PK parameters (e.g., AUC0-t should 
cover at least 80% of AUC0-∞) of Cycle 1 and 2. Evaluable patients 
should have received the first two complete cycles regardless dose 
delays or reductions.
For Part A and Part B, the compliance of itraconazole will be 
confirmed based on a patient’s diary, the drug accountability and
the expected individual plasma concentration at the steady state.
EVALUATION 
CRITERIA
Primary endpoint
Plasma exposure to lurbinectedin: Plasma dose-normalized Cmax
and AUC0-∞of lurbinectedin will be compared between Cycle 1 and 
Cycle 2. Pharmacokinetic analyses will be evaluated in plasma by 
standard non-compartmental methods, or population methods, if 
necessary. 
Secondary endpoints

Secondary PK parameters:
o Differences in dose-normalized total AUC0-t and Cmax and in 
Cl, Vss and T1/2 of lurbinectedin between Cycle 1 and Cycle 2 
will be explored.
o Differences in dose-normalized unbound AUCu,0-∞, AUCu,0-t
and Cu,max and in CLu, Vss,u and T1/2,u of lurbinectedin between 
Cycle 1 and Cycle 2 will be explored.
o Differences in ratios between total AUC0-∞, AUC0-t and Cmax, 
of main lurbinectedin metabolites relative to parent drug
between Cycle 1 and Cycle 2 will be explored. Additional PK 
parameters will be calculated if deemed appropriate.

Safety: patients will be evaluable for safety if they have 
received at least one partial or complete infusion of 
lurbinectedin. AEs, serious adverse events (SAEs) and 
laboratory abnormalities will be graded according to the NCI-
CTCAE v.5. Additionally, treatment compliance, in particular 
dose reductions requirements and/or treatment delays due to 
AEs, and reasons for treatment discontinuation will also be 
described.

Pharmacogenetics:
the 
presence 
or 
absence 
of 
PGt 
polymorphisms in genes relevant for lurbinectedin disposition 
(distribution, metabolism and excretion) from a single blood 
sample collected at any time during the trial (but preferably at 
the same time as the pre-treatments PK sample on Day 1 of 
Cycle 1), which will be stored to explain individual variability in 
main PK parameters in future analyses.

CRITERIA FOR 
TREATMENT 
CONTINUATION
Patients may continue treatment with lurbinectedin as long as no 
unacceptable toxicity and/or progression of the disease occurred, 
and for a maximum of three cycles. Thereafter, treatment with 
lurbinectedin can continue under a Compassionate Use Agreement.
In Part A and Part B, patients assigned to Sequence 1 (TR)
(lurbinectedin + itraconazole in Cycle 1), after Cycle 1 the 
administration of a new cycle should be delayed if the criteria in 
Table S2 are not met on the corresponding Day 1. Re-assessments 
will be performed periodically at intervals of at least 72 hours but 
not more than one week. Lurbinectedin administration should be 
delayed until recovery of these parameters. A maximum delay of 14 
days from the theoretical due date will be allowed for recovery from 
treatment-related adverse events. If recovery has not occurred after 
that period, the patient should discontinue the treatment, except in 
case of obvious patient benefit at the criteria of the Investigator and 
upon agreement with the Sponsor. 
In Part B, patients assigned to Sequence 2 (RT) (lurbinectedin + 
itraconazole in Cycle 2), criteria for treatment continuation should 
be investigated on Day 15 of Cycle 1 in order to confirm 
itraconazole administration start on Day -4 of Cycle 2, assuring that 
the continuation criteria will be finally met on Day 1 of Cycle 2 
assessment. In case of detected abnormalities on Day 15 in 
sequence RT, these assessments should be repeated every 48-72 
hours until recovery to retreatment criteria. Initiation of itraconazole 
will be delayed for a maximum of 14 days to ensure that pre-
treatment with itraconazole is fulfilled. If recovery has not occurred 
after that period, the patient should discontinue the treatment, 
except in case of obvious patient benefit at the criteria of the 
Investigator and upon agreement with the Sponsor.
Re-treatment criteria for lurbinectedin administration should be met 
on Day 1 of Cycle 2.
Any patient having any grade ≥ 3 laboratory abnormalities and/or 
treatment-related AEs after Cycle 2 or Cycle 3 is suggested to have 
the relevant tests re-assessed at intervals of at least 72 hours but not 
more than one week.
If they were not met, treatment will be delayed for a maximum of 2 
days to evaluate continuation of lurbinectedin administration, with 
re-treatment criteria being checked every 24 hours. During this time 
the patient will continue receiving itraconazole. If after 2 days of 
delay the patient does not meet the criteria for treatment 
continuation, itraconazole will be stopped and the patient will be 
considered not evaluable for the trial.

(except in case of obvious patient benefit at the criteria of the Investigator and upon agreement 
with the Sponsor).
Sequence 2 (RT):
If a patient does not meet the requirements for treatment continuation on Day 15 of Cycle 1, 
treatment with itraconazole will be withheld until recovery for a maximum of 14 days after the 
theoretical treatment date. If recovery has not occurred after a delay of > 14 days, discontinue 
treatment (except in case of obvious patient benefit at the criteria of the Investigator and upon 
agreement with the Sponsor).
If a patient does not meet the requirements for treatment continuation on Day 1 of Cycle 2, 
treatment with lurbinectedin will be withheld until recovery for a maximum of 2 days after the 
theoretical treatment date. During this time, the patient will continue receiving itraconazole. If 
recovery has not occurred after a delay of > 2 days, itraconazole will be stopped and the patient 
will be considered not evaluable for the trial.

DOSE REDUCTION
Patients may continue in the study treatment at a lurbinectedin 
reduced dose if they present any of the following:

Grade 4 thrombocytopenia or grade 3 thrombocytopenia 
concomitantly with grade ≥3 bleeding.

Two dose delays or prolonged (> one week) dose delay due to 
treatment-related adverse events.

Grade ≥
3 treatment related non-hematological toxicity.
Exceptions are: grade ≥3 nausea and/or vomiting not optimally 
treated, grade 3 fatigue lasting < two days, grade 3 diarrhea 
lasting < one day or non-optimally treated, isolated grade 3 
transient ALT/AST elevations which are rapidly reversible and 
not leading to subsequent delays, and non-clinically relevant 
isolated biochemical abnormalities.

Grade 4 neutropenia or any grade febrile neutropenia. 
Up to two lurbinectedin dose reductions are allowed per patient. 
Patients who continue to experience treatment-related toxicity 
and/or dose delays after two dose reductions must be withdrawn 
from the study. Once the dose has been reduced for an individual 
patient, it will not be re-escalated under any circumstances.
Lurbinectedin dose reduction levels are shown in Table S3.

of lurbinectedin unbound fraction (fu).                                         
PHARMACOGE-
NETICS
In order to explore factors that may help explain individual
variability in the main PK parameters, the presence or absence of
germline mutations or polymorphisms will be analyzed in leukocyte
DNA extracted from a blood sample obtained at any time during the 
study, but preferably before infusion start along with PK sample #1 
on Day 1 of Cycle 1.
STATISTICAL 
METHODS
This clinical pharmacology study is designed to assess the impact of 
itraconazole co-administration on lurbinectedin PK parameters 
administered alone.
Analysis populations:
The PK population will include all patients enrolled in Part A and B 
who have sufficient and interpretable PK parameters to calculate the 
non-compartmental PK parameters. Only the patients in Part B who 
have completed the two cycles and have sufficient and interpretable 
PK assessments will be included in the statistical comparison to 
assess the effect of itraconazole on the PK of lurbinectedin.
The safety population will include all patients who received at least 
one dose of lurbinectedin. Patients who have received at least one 
dose of itraconazole but who did not receive any dose of 
lurbinectedin will be excluded from the safety population. The 
analysis of data from these patients will be performed separately
e.g., by means of narratives). The safety population will be used for 
all safety evaluations.
Sample size:
A block randomization (1:1 ratio) will be performed only in Part B.
At least 11 patients (three patients in Part A followed by eight 
patients in Part B) are expected to complete all study procedures,
including the collection of sufficient and interpretable PK 
assessments. Although at least 11 patients will be enrolled in this 
study; it is estimated that complete data from eight patients will be 
sufficient to estimate the drug-drug interaction of itraconazole on
the PK of lurbinectedin. In case of patient replacement, a new 
patient number will be provided and he/she will be assigned to the 
same sequence as the patient being replaced.
This study was designed to assess the potential effects of 
itraconazole on the PK of lurbinectedin in patients with advanced 
malignancies. A sample size of eight patients was based on 
feasibility and clinical considerations. Based on previous studies, 
the intra-subject coefficient of variation (CV) of lurbinectedin PK 
parameters is estimated to be more than 30%. The precision (half-
width) of the 90% CI for [(lurbinectedin + itraconazole) / 
lurbinectedin alone] comparison on the log-scale will extend 0.389 
from the observed differences in means, assuming that the intra-
subject CV around 40%. This half-width corresponds to a 90% CI 
in the range of 70% and 147% assuming the ratio of the means 
equal to unity for each PK parameter. This 90% CI will be used to 
help with the interpretation of the results.

Protocol PM1183-A-018-20
Plasma exposure to lurbinectedin:
Only patients who completed the study with sufficient and 
interpretable PK parameters will be included in the statistical 
comparison of plasma exposure to lurbinectedin.
Descriptive statistics will be used to summarize pharmacokinetic 
data.
The primary parameter of interest for the statistical analysis will be 
plasma dose-adjusted AUC(0-∞) (if data do not permit so, AUC(0-t)
will be used) of lurbinectedin. The analysis will compare the log-
transformed AUC for lurbinectedin administered in combination 
with itraconazole (Test) to the lurbinectedin alone (Reference). 
A mixed-effects model will be fit to the data with log-transformed 
AUC as the dependent variable, treatment (Test or Reference), 
period and sequence as fixed effects, and patient (sequence) as a 
random effect. The estimated least square means and intrasubject 
variability from the mixed-effects model will be used to construct 
90% CIs for the difference in means on the log scale between 
treatments (Test or Reference). The adjusted mean differences and 
the 90% CIs will be exponentiated to obtain estimates of the ratio of 
adjusted geometric means (Test/Reference) and 90% CIs for the 
ratios.
A large difference (e.g. two-fold difference shown from CIs and 
least square means) will be considered to show evidence on whether 
itraconazole co-administration has a clinically relevant effect on 
lurbinectedin exposure.
Secondary PK parameters:
Similar models used for the primary endpoint will be fit to the data 
with dose-normalized AUC(0-t) and Cmax and in Cl, Vss and T1/2 of 
lurbinectedin or metabolite to parent exposure PK parameters ratio, 
as the dependent variable. Results will also be assessed graphically.
Plasma protein binding:
A similar model used for the primary endpoint will be fit to the data 
with dose-normalized AUCu as the dependent variable.
Safety:
Descriptive statistics will be used to characterize the profiles of 
drug-related AEs, drug-related deaths, SAEs, clinical laboratory 
data, drug-related delays and/or treatment discontinuations.  All 
AEs will be graded according to NCI-CTCAE v.5. Tables will be 
displayed by study part, sequence and treatment (Test or 
Reference).
Pharmacogenetics:
Descriptive statistics will be used to summarize pharmacogenetic 
data at the time of planned analysis.
PLANNED TRIAL 
PERIODS
(individually per 
patient)
Patients will be evaluated at scheduled visits in three study periods:

Pre-treatment (screening): from signature of the ICF to the 
day of first administration of the study treatment (itraconazole 
or lurbinectedin).

Treatment: from first administration of the study treatment 
(itraconazole or lurbinectedin) to the last dose of lurbinectedin 
plus 31 days (end-of-treatment, EOT) (maximum of three 
cycles).

Follow-up: after EOT, patients with treatment-related toxicities 

CL_0363 3.0
Page 21 of 93
Protocol PM1183-A-018-20
> grade 2 will be followed every four weeks until recovery to at 
least grade 1 or stabilization of all treatment-emergent AEs, or 
until the start of a new antitumor therapy, until the continuation 
of treatment outside this study under a Compassionate Use 
Agreement or death, whichever occurs first.
Patients will be considered to be on-study from the signature of the 
ICF to the end of the follow-up period. Patients will be considered 
to be on-treatment for the duration of their treatment and until the 
day of EOT, immediately before the start of the follow-up period. 
An end-of-treatment (EOT) visit will be performed within 31 days 
(±10 days) after administration of the last dose of lurbinectedin, 
unless the patient dies or starts any new antitumor therapy outside 
this clinical study, in which case the EOT visit should be performed 
immediately before the start of the new therapy (ideally the day 
before or the same day).
PLANNED TRIAL 
PERIODS (for the 
whole study)
The total duration of the study will be approximately 22 months, 
including approximately an 18-month enrolment period. 
Planned start date (first patient on study): 3Q2020.
Planned enrollment period: approximately 18 months.
Planned end-of-study date (clinical cutoff): 31 (±10) days after the 
date of the last lurbinectedin administration for last patient/last 
cycle, or when confirmation of evaluability of at least eight patients 
in Part B, whichever occurs last. 
Patients who meet the continuation criteria and obtain a clear 
clinical benefit with lurbinectedin after the completion of the first 
two study cycles, according to the Investigator’s criteria may 
continue treatment outside this study under a Compassionate Use 
Agreement after the completion of the optional third study cycle. 
Should the patient continue under a Compassionate Use Agreement, 
the treating center must request authorization to the relevant Health 
Authorities and notify the Sponsor in due time.

Registration = confirmation of eligibility and inclusion; Day 1 = the day of lurbinectedin administration (with infusion start) of cycle 1 or 2; Day 8 = seven days after the lurbinectedin administration of 
cycle 1 or 2 (±2 days); Day 15 = fourteen days after the lurbinectedin administration of cycle 1 or 2 (±2 days).
* Permitted windows for assessments before Day 1 of Cycle 1:
If physical examination, ECOG PS, vital signs, Hematology, Biochemistry-A, Biochemistry-B, CLcr (provided only if serum creatinine levels are above ULN) and Coagulation were assessed >10 days before Day 1 
of Cycle 1, the tests must be repeated the day before or the Day 1 (always prior to lurbinectedin infusion).
If pregnancy test was done >7 days before Day 1 of Cycle 1, the test must be repeated the day before or the Day 1 (always prior to lurbinectedin infusion). 
A patient should only be treated if eligibility criteria are still met according to assessments performed closest to treatment start.
Permitted windows for assessments after Day 1 of Cycle 1:
A ± 2-day time window will be allowed for Hematology, Biochemistry-A and CLcr (provided only if serum creatinine levels are above ULN) on Day 8 and Day 15, and for vital signs on Day 8 of Cycle 1.
A -1 day window will be allowed for physical examination, ECOG PS, vital signs, Hematology, Biochemistry-A, and Biochemistry-B, CLcr (provided only if serum creatinine levels are above ULN) and Pregnancy 
test on Day 1 of Cycle 2 and further cycles (always prior to lurbinectedin infusion).
A + 2 days window for Day 1 lurbinectedin administration of Cycle 3.
If a drug administration is delayed beyond the permitted protocol window, assessments planned for the original administration day must be repeated on the day the dose is finally administered.
a Should treatment be administered more than ten days after the screening tests, repeat these tests prior to the first infusion and if clinically indicated. Height needs to be measured at baseline only. BSA will not be 
reported at the EOT. BSA calculated according to DuBois formula (see Appendix 4).
b Any patient having any grade ≥ 3 laboratory abnormalities and/or treatment-related AEs is suggested to have the relevant tests re-assessed at intervals of at least 72 hours but not more than one week until recovery 
to at least grade 2 has been documented.
c Repeat during treatment period and at EOT if clinically indicated.
d Calculated CLcr [Cockcroft and Gault’s formula] should be provided only if serum creatinine levels are above ULN.
e ECG should be done in triplicate (at screening, Day 1 and at EOT visit) and allow rhythm definition (at least 30 seconds of duration), PR interval and QT interval (raw and corrected by HR using Bazett’s 
formula). On Day 1, 5 minutes before SOI (-25 to -1 min before preinfusion PK samples collection) and 1 hour after EOI (-15 to -1 min before the PK sample collection), both will be done in triplicate.
f A previous LVEF assessment could be used if was made within 28 days prior to screening and during treatment period and at EOT will be repeated only if clinically indicated.
g Randomization apply for study Part B only.
h Itraconazole for self-administration and the patient’s diary should be given to the patient on Day -5 with a -2/+1 day time window (i.e., from Day -7 to Day -4). 
i Corticosteroids i.v. (according to institutional standard antiemetic doses, minimum dose of 8 mg/day and maximum dose of 20 mg/day of dexamethasone sodium phosphate or equivalent); If feasible, anti-emetic 
medication and dose administered in Cycle 1 should be maintained in Cycle 2. Serotonin (5-HT3) antagonists (ondansetron at least 8 mg i.v. and no more than 16 mg of ondansetron) (i.e., 30 ± 5 minutes before

j If patient does not fulfill inclusion criteria (Cycle 1 in TR sequence) in Day 1 assessments and lurbinectedin administration is postponed no more than two days, itraconazole should not be discontinued.
k The study center will contact the patients (via telephone or other methods) to remind them or confirm that they have taken the morning dose of itraconazole when they are not at the study center.
l Blood sample for genotyping will be collected at any time during the study but preferably just before infusion start in Cycle 1, only if written IC for the pharmacogenetic sub-study is given.
m Serial peripheral venous blood samples for determination of lurbinectedin (total and unbound), lurbinectedin metabolites (i.e., M1 and M4) and itraconazole (as well as, its active metabolite, hydroxy-itraconazole) 
plasma concentrations will be collected at the time points indicated in Section 8.1.1, Table 9.
n Clinical assessment of the patient’s signs and symptoms (including nurses’ assessment and patient-reported issues) should continue on an ongoing basis throughout the study and be reported at least every cycle as 
AEs. Only information on SAEs that occurred after signature of the informed consent and up to Day -5 is required before treatment start. Grading should be as per the NCI-CTCAE v.5. Signs and symptoms will be 
assessed by the Sponsor as all the events ongoing during the screening period, except for prior history conditions, which should be reported in the medical history form. Ongoing events during the screening period 
are those present at any time between the informed consent date and the first drug administration, regardless of if they may be resolved or not at the date of Cycle 1 Day 1.
o The “AE form” will be used only for events that occur after the first drug infusion or any event related to a study procedure within the study period (according to ICH guidelines); and to report ‘ongoing’ baseline 
conditions in case of any significant change (improvement or worsening) during the study.
p Patients will be followed every four weeks until recovery to at least grade 1 or stabilization of all treatment-emergent AEs, or until the start of a new antitumor therapy, until the continuation of treatment outside 
this study under a Compassionate Use Agreement or death, whichever occurs first.

INTRODUCTION
1.1
INFORMATION ON THE STUDY DRUG: LURBINECTEDIN
Lurbinectedin is a novel synthetic chemical entity composed of a pentacyclic skeleton 
formed by two fused tetrahydroisoquinoline rings with an additional tetrahydro--
carboline moiety (Figure 1).
Lurbinectedin is an inhibitor of oncogenic transcription. It recognizes specific 
sequences in the minor groove of the DNA where it forms adducts that ultimately lead 
to the generation of double-strand breaks (DSBs). Additionally, it induces the specific 
degradation of transcribing RNA Pol II and the eviction of transcription factors from the 
promoters of actively transactivated genes. It is specifically active in tumors addicted to 
transcription. The generation of DSBs triggers an extended delay in the transition 
through phase S of the cell cycle with an arrest in the phases G2/M, leading to tumor 
cell death by apoptosis.
In vitro, lurbinectedin demonstrated cytotoxic effects against a broad selection of tumor 
types with half maximal inhibitory concentration (IC50) values in the range of 1-10 nM. 
Although selectivity was also seen, a clustering of sensitive tumors has not been 
identified. Lurbinectedin also exhibited antitumor activity against different murine 
models of xenografted human-derived tumor types. Lurbinectedin has been tested as a 
single agent or in combination with different drugs in solid tumors; while antitumor 
activity in hematological tumors was deemed negligible, lurbinectedin has shown 
activity in different solid tumors; some of the most responsive tumor types were breast, 
small cell lung cancer (SCLC), ovarian and endometrial cancer. 
Based on current clinical data, the toxicity of lurbinectedin is predictable, reversible and 
manageable. The most relevant toxicity is reversible myelosuppression with a nadir 
occurring in the middle of the second week after Day 1 infusion in an every-three-week 
cycle; overall, the incidence of febrile neutropenia is below 20% in all ongoing Phase II 
trials.

1.1.2
Non-clinical Data
The pentacyclic skeleton of lurbinectedin is mostly responsible for DNA minor groove 
recognition and binding. Lurbinectedin reacts with exocyclic amino group of guanines 
in the minor groove of DNA forming a covalent bond. Lurbinectedin preferentially 
binds the following triplet of bases: AGC>CGG>TGG>AGG>GGC (the middle 
guanine being the site for covalent adducts formation), in the promoter of actively 
transcribed genes [1].  
From the mechanistic point of view, lurbinectedin is an inhibitor of oncogenic 
transcription, inducing the eviction of oncogenic transcription factors from their binding 
sites within the chromatin and their redistribution within the nucleus [2]. Secondarily, 
Lurbinectedin inhibits active transcription through specific and rapid degradation of 
transcribing RNA Pol II, preventing RNA Pol II elongation and consequently RNA 
synthesis, as observed in several human tumor cell lines [1].
Phosphorylated histone H2AX is detected in lurbinectedin-treated cells extracts after the 
disappearance of RNA Pol II, indicating the presence of DSBs. In the process of 
generation of DSBs, the nucleotide excision repair (NER) machinery has a relevant role 
[1, 3]. The presence of the lurbinectedin-DNA adduct in a DNA strand causes that the 
XPF/ERCC1 nuclease of the NER system, instead of repairing the affected strand, 
generates breaks on the opposite DNA strand generating DSBs [1]. Indeed, 
lurbinectedin is less potent in NER-deficient cells than in NER-proficient cells. 
Resistance to DNA alkylators and platinum treatments is often accompanied by 
increased NER activity, suggesting that these platinum-resistant tumor cells could be 
sensitive to lurbinectedin. In vitro, lurbinectedin showed enhanced and similar activity 
towards two cisplatin-resistant ovarian carcinoma cell lines and oxaliplatin-resistant 
colon carcinoma cell lines [3, 4].
DSBs need to be repaired by the Homologous Recombination (HR) System. The non-
homologous end joining (NHEJ) and HR repair pathways have been investigated in 
different cell systems in the activity of lurbinectedin [4, 5]. Lurbinectedin is more active 
against homologous recombination-deficient (HRD) cell lines such as BRCA mutated 
cells [4, 6, 7]. HR deficient cells have a sensitive profile, 50 to 100 times higher than 

CL_0363 3.0
Page 34 of 93
Protocol PM1183-A-018-20
parental lines, possibly due to the persistence of unrepaired DSB during the S phase and 
the subsequent increase in apoptosis [5].
As a final consequence of its mechanism of action, lurbinectedin induces delayed 
transition through the phase S of the cell cycle and a final arrest in the G2/M phases, 
triggering tumor cell death by apoptosis [8].  
Lurbinectedin has demonstrated strong in vitro antineoplastic activity in several human 
cancer cell lines, representative of prostate, pancreas, ovary, non-small cell lung cancer 
(NSCLC) and SCLC, liver, leukemia, lymphoma, kidney, gastric, colon and breast 
tumor cell lines, with 50% inhibitory concentration (IC50) values ranging from 0.3 to 
64.5 nM. Moreover, in a dedicated panel composed of 15 human SCLC cell lines, the 
compound showed compelling cytotoxic activity, with an average IC50 of 0.65 nM. 
The in vivo antitumor activity of lurbinectedin was also demonstrated in a panel of 
different types of human-derived experimental tumors. Statistically significant tumor 
volume reduction has been observed in several xenograft models such as SCLC, 
NSCLC, glioma, breast, gastric, kidney, ovary and pancreas tumors. After treatment, 
molecular analysis of these tumors showed a significant increase of γ-H2AX as well as 
a reduction of tumor-associated macrophages (TAMs) [4]. The antitumor effect of the 
drug has been demonstrated in mice bearing different patient-derived xenografts of 
pancreatic ductal carcinoma and in mice bearing orthotopic tumors (pancreas, ovary and 
Ewing sarcoma): in all these models, the drug caused a significant tumor size reduction 
compared to placebo-treated animals.
Lurbinectedin presents a marked effect on tumor microenvironment by inhibiting 
transcription and secretion of tumor-growth promoting cytokines by TAMs [9]. In vivo, 
synergistic anti-tumor effect was demonstrated for the combination of lurbinectedin and 
immune checkpoint blockade (anti-PD1 antibody and anti-CTLA4 antibody) in a 
murine fibrosarcoma MCA205 model [10].
Liver microsomal fractions from human, as well as from other animal species (i.e. 
mouse, rat, guinea pig, dog and non-human primates [NHP]), were incubated with 
unlabeled or 14C1-lurbinectedin. Results showed that lurbinectedin was stable in the 
liver microsomes from these species in the absence of NADPH-regenerating system, 
indicating that the metabolism of lurbinectedin is NADPH-dependent. After the 
incubation period (10 min), 14C1-lurbinectedin was nearly or completely metabolized in 
liver microsomes from NHP, mouse and human, indicating that lurbinectedin undergoes 
an intense and rapid NADPH-dependent microsome-mediated metabolism. The NHP 
was the preclinical specie that exhibit the most qualitatively and quantitatively human-
similar microsome-mediated metabolism.
Experiments performed with human microsomes (both genders) and selective chemical 
inhibitors and inhibitory monoclonal antibodies directed against CYP1A2, 2A6, 2B6, 
2C8, 2C9, 2C19, 2D6, 2E1, and 3A4 pointed to CYP3A4 as the main CYP isoform 
involved in the phase I metabolism of lurbinectedin. The involvement of other CYPs in 
the microsome-mediated metabolism of lurbinectedin was demonstrated to be negligible 
[11, 12].
The interaction of lurbinectedin on several human ATP-binding cassette (ABC) efflux 
transporters, namely BCRP (ABCG2), BSEP (ABCB11) and MDR1 (ABCB1/P-gp), as 
well as several human uptake transporters, namely MATE1 (SLC47A1), OATP1B1 
(SLCO1B1), OATP1B3 (SLCO1B3), OAT1 (SLC22A6), OAT3 (SLC22A8), OCT1 

CL_0363 3.0
Page 35 of 93
Protocol PM1183-A-018-20
(SLC22A1) and OCT2 (SLC22A2) were evaluated in in vitro studies. Results have 
shown lurbinectedin is substrate of MDR1 (ABCB1) transporter.
In vitro, the percent of lurbinectedin bound to human plasma proteins was very high 
(>99%) and independent of drug concentration. Lurbinectedin binds to both human 
serum albumin and α-1-acid glycoprotein (AAG), with higher affinity to AAG. In vitro 
binding to AAG is linear and non-saturable at clinically relevant concentrations.
In non-clinical species (rat, dog, and monkey), lurbinectedin exhibits low to moderate 
plasma clearance (from 1 to 10 L/h/kg) and large volume of distribution (from 2 to 56 
L/Kg). The elimination half-life was long (from 9 to 22 h).
In non-clinical toxicity studies, lurbinectedin reversibly affected the hematopoietic 
system, mainly reducing reticulocytes and white blood cells and inducing a slight 
anemia, as well as bone marrow (BM) depletion and atrophy of the lymphoid system. 
Hepatotoxicity was observed mainly in rats and was characterized by markedly 
increased liver function tests, hepatocellular necrosis and biliary damage. 
Hepatotoxicity was less pronounced in dog studies. 
Other target organs, mainly identified in rats, were atrophy of the gastrointestinal (GI) 
mucosa, adrenal gland cortical hypertrophy and kidney cortical tubular vacuolization. In 
summary, the main toxic effects of lurbinectedin – transient BM suppression and 
hepatotoxicity – are rather commonly seen with cytotoxic drugs.
Injection site lesions were also seen in studies regardless of the animal studies used. 
These lesions were characterized by perivascular hemorrhage, inflammation, edema and 
chronic phlebitis, necrosis and ulceration. 
More information is available in the Investigator’s Brochure (IB) of lurbinectedin.
1.1.3
Clinical Data
Up to the cut-off date of 15 January 2020 (date of last IB), a total of 2474 patients had
been included in PharmaMar clinical studies evaluating lurbinectedin; 975 of them 
(39.4%) were treated with lurbinectedin as single-agent; three phase 1 studies in solid 
and hematological tumors at different regimes [day 1, days 1 and 8, and days 1-3 in 
cycles of 3 weeks (q3wk)], five phase 2 studies in different tumor types [pancreatic, 
ovarian, breast, NSCLC and selected aggressive solid tumors including SCLC] and one 
phase 3 study in ovarian cancer.
1.1.3.1 Phase I Trials
Currently, this program comprises four single-agent studies, three in solid tumors (one 
ongoing in Japanese patients) (Table 1) and one in acute leukemia patients, six phase Ib 
combination studies with gemcitabine (GEM), capecitabine, doxorubicin (DOX), 
cisplatin, paclitaxel with or without bevacizumab (BEV), and irinotecan in patients with 
selected advanced solid tumors. 
The First-in-Human (FiH) study (PM1183-A-001-08) was conducted in patients with 
advanced and refractory solid tumors and evaluated lurbinectedin intravenously (i.v.)
infused over one hour every three weeks (q3wk). Thirty-three patients were included 
and thirty-one patients were treated. The recommended dose (RD) was stablished at an 
equivalent dose of 4.0 mg/m2/q3wk [13]. Since lurbinectedin clearance was found to be 
unrelated to body surface area (BSA), all patients in the RD expansion cohort were 
treated at a flat dose (FD) of 7.0 mg q3wk (equivalent to 4 mg/m2). However, further 

CL_0363 3.0

Protocol PM1183-A-018-20
linear regression showed a strong correlation between neutropenia and its severity with 
the systemic exposure (area under the concentration-time curve – AUC), and for this 
reason, lurbinectedin prescriptions are currently calculated against BSA; moreover, 
phase Ib trials started with a FD and were amended to use a BSA-based dose. In this 
study (and subsequent studies), the median terminal plasma half-life (T1/2) was around 
60 hours, with a plasma clearance (CL) close to 12 L/h though large inter-individual 
variability exists. Urinary excretion of unaltered lurbinectedin was almost negligible 
regardless of dose; the mean percentage of unaltered drug recovered in urine at the 
recommended dose was 0.23% [13].
The most relevant toxicity found in the FiH trial was reversible myelosuppression, 
notably grade 4 non-febrile neutropenia in 40% of patients treated at the RD in Cycle 1. 
Neutropenia was generally predictable and short-lasting and rarely caused treatment 
delays with nadir usually occurring during the second week. No cases of febrile 
neutropenia occurred in this study, although patient selection might have played a role. 
Also, at the RD, treatment was generally well tolerated, with no grade 4 transaminase 
increases observed (in contrast to what occurred above the RD). No unexpected 
toxicities occurred in this study, and there were no signs of cumulative toxicity. All 
patients at this dose level were treated with standard antiemetic prophylaxis to control 
grade 2 nausea and/or vomiting [13].
There was one partial response as per the Response Evaluation Criteria in Solid Tumors 
(RECIST v. 1.0) in pancreatic cancer and three disease stabilizations (SD) at the RD 
lasting ≥ 4 months (two in soft tissue sarcomas, one in melanoma) [13]. 
To explore the feasibility of an alternative schedule (Day 1 and 8, q3wk), a second 
phase I trial (PM1183-A-005-11) was started in advanced non-colorectal cancer patients 
following a prospective FD escalation. The RD was 5 mg FD on Day 1 and 8 q3wk.
Myelosuppression limited further dose escalation; in contrast to the FiH trial, grade 4 
neutropenia lasted longer and there were more drug-related dose delays/omissions [14]. 
Based on the results from single-agent phase I clinical trials in solid tumors, the Day 1 
q3wk schedule was assessed as more convenient with better compliance, and was  
selected for further clinical trials.

With regards to lurbinectedin antitumor activity in hematological tumors, the only 
available information comes from one phase I trial (PM1183-A-002-10), where the 
clinical activity of lurbinectedin was considered negligible from the clinical point of 
view in patients with advanced acute leukemia. For this reason, drug development in 
this hematological disease is not warranted.
1.1.3.2 Human Mass Balance Study
In the human mass balance study (PM1183-A-015-16), near complete recovery of 
administered radioactivity (94.3±8.7%) was achieved within 500-hour post-dose 
following a single mass dose of 4.29±0.23 mg of [14C1]-lurbinectedin (radioactive dose 
of 74.28±8.62 µCi) administered as 1-hour i.v. infusion. The majority of radioactivity 
was excreted in feces (88.7±10.1%) with minimal excretion in urine (5.6±2.0%). Whole 
blood to plasma ratio of parent-related [14C]-radioactivity based upon mean AUC0-last
were found to be 0.68 indicating larger distribution in plasma.
The mean plasma lurbinectedin time to peak (tmax) and plasma [14C]-radioactivity was 
found to be similar (1.2 h). Mean plasma [14C]-radioactivity Cmax, AUC0-last and AUC0-
inf were 1.4, 1.6 and 1.9-fold higher as compared to parent compound. Mean plasma 
[14C]-radioactivity t1/2 (55-hour) was 1.2-fold longer than plasma lurbinectedin t1/2 (47-
hour). Mean plasma clearance and volume of distribution of parent compound were 
found to be 1.7- and 2.1-fold higher than plasma [14C]-radioactivity. According to 
AUC0-last comparison, lurbinectedin constituted approximately 62% of the total [14C]-
radioactivity in plasma, thus suggesting that parent compound is the main circulating 
moiety in plasma.
Among the five known lurbinectedin metabolites (M1 to M5), all were detected but only 
four (M1, M4 (PM030047), M3 (PM01158), and M2 (PM030036)) were quantified in 
plasma. M5 (PM030779) could not be quantified, but its presence in plasma, at low 
levels (around its LLOQ of 0.1 mg/mL), was demonstrated.
Up to 10-hour after the end of infusion, 88.7% of the total [14C]-radioactivity in plasma 
can be attributed to lurbinectedin (70.2%) plus these four metabolites (18.5%). Based on 
these results, M1 and M4 (PM030047) were the major metabolites accounting for 10% 
and 7.3% of circulating radioactivity, respectively, thus representing 14.3% and 10.4% 
of the parent compound in plasma.

1.1.3.3 Phase II Trials
As of 15 January of 2020, five phase II clinical studies had explored the efficacy of 
lurbinectedin in specific solid tumor types and settings (Table 3): PM1183-B-001-10 in 
pancreatic cancer as second-line therapy post GEM-based failure; PM1183-B-002-11 in 
platinum-resistant/refractory ovarian cancer; PM1183-B-003-11 in previously treated 
BRCA1/2-associated metastatic breast cancer (MBC); PM1183-B-004-13 in NSCLC,
and PM1183-B-005-14 in selected advanced solid tumors.
Four of these studies initially evaluated single-agent lurbinectedin at the RD and 
schedule determined in the FiH study (PM1183-A-001-08), i.e., 7.0 mg FD as a 1-h i.v. 
infusion q3wk. In addition, study PM1183-B-004-13 evaluated lurbinectedin in 
combination with GEM at the RD and schedule defined in a previous phase I study 
(PM1183-A-004-10), i.e., lurbinectedin 3.0 mg FD + GEM 800 mg/m2 both on Day 1 
and Day 8 q3wk. However, protocol amendments were implemented to change the fixed 
dose in these studies to a BSA-based dose, as a conservative approach after knowledge 
of data suggesting BSA-related toxicity. The fifth study (PM1183-B-005-14) evaluated
lurbinectedin at a BSA-based dose of 3.2 mg/m2 as a 1-h i.v. infusion q3wk.

1.1.3.4 Phase III Program
As of 15 January 2020, one completed phase III study (PM1183-C-004-14, CORAIL) 
had compared the efficacy of lurbinectedin in platinum-resistant ovarian cancer against 
standard topotecan or pegylated liposomal doxorubicin (PLD). No significant 
differences between treatment arms were found for secondary efficacy endpoints of this 
trial. Lurbinectedin showed an improvement in terms of safety profile compared to the 
control arm.
The other
phase
III clinical study is currently ongoing
(PM1183-C-003-14, 
ATLANTIS). This study had completed recruitment. The aim of this study is to 
compare the combination of lurbinectedin with DOX vs. treating physician choice 
(topotecan or CAV) as a second line in SCLC. 
1.1.3.5 Population Pharmacokinetic and Pharmacodynamic (PKPD) Modeling
A population pharmacokinetic model of lurbinectedin was developed by pooling data 
from all studies (including drug combination studies) and it is regularly updated.
A population pharmacokinetic three-compartment model with linear elimination and 
linear distribution adequately fits the PK data. The model estimated a mean (standard 
deviation [SDev]) CL of 12.3 (7.0) L/h, a half-life (HL) of 47.2 (31.5) hours and a wide 
volume of distribution at steady state (Vss) of 436 (250) L. All these PK parameters 
showed high variability (coefficient of variation [CV] about 50%) among patients. The 
lurbinectedin PK showed linearity among the dose range explored (0.5-4.5 mg/m2).
Baseline covariates affecting lurbinectedin CL are albumin, alpha 1-acid glycoprotein, 
BSA, the presence of strong (voriconazole) or moderate (aprepitant or fluconazole) 

CL_0363 3.0
Page 41 of 93
Protocol PM1183-A-018-20
CYP3A4 inhibitors, and cardiac function measured by left ventricular ejection fraction 
(LVEF). The use of strong (voriconazole) or moderate (fluconazole or aprepitant) 
CYP3A4 inhibitors reduced lurbinectedin CL by approximately 40% and 20%, 
respectively. Therefore, the use of CYP3A4 inhibitors should be carefully monitored or 
avoided, whenever possible. 
Renal elimination of lurbinectedin was minor in the FiH trial. In addition, the 
population PK model did not establish any relationship between lurbinectedin CL and 
CLcr or creatinine levels. Age and race were found to have no effect over lurbinectedin
PK, although the number of elderly patients (>75 years) and non-Caucasian patients was 
small.
Lurbinectedin-induced neutropenia and thrombocytopenia population PKPD models 
showed that baseline ANC and platelet count are by far the covariates with the greatest 
effect on the incidence of neutropenia and thrombocytopenia. With a baseline absolute 
neutrophil count (ANC) value of 2.0 x 109/L (currently the lower limit of ANC for 
inclusion is 1.5 x 109/L), and a platelet count of 135 x 109 (currently the lower limit of 
platelet count for inclusion is 100 x 109/L), the incidence of grade 3/4 neutropenia and 
thrombocytopenia were estimated to be around 69% and 13%, respectively, in the first 
cycle. Simulations performed at 3.2 mg/m2 showed a lower neutropenia and 
thrombocytopenia incidence compared to the previous RD of 7.0 mg FD. The results of 
the simulation also showed that BSA-dosing reduced the variability caused by BSA 
compared to 5.7 mg FD. The presence of ascites or the use of CYP3A4 inhibitors would 
increase the incidence of neutropenia, while the use of G-CSF would decrease it 
markedly. Additionally, breast cancer patients showed less risk of developing 
thrombocytopenia, while the use of strong CYP3A4 inhibitors, ascites or pancreatic 
cancer increased this risk. The population PK model of lurbinectedin showed that CL 
increases with BSA, and the population PKPD models for neutropenia and 
thrombocytopenia showed myelosuppression would be decreased by BSA dosing. 
Therefore, the use of a BSA-dosing strategy for lurbinectedin has been resumed in 
ongoing and planned trials.
1.2
OVERALL STUDY RATIONALE
Lurbinectedin is extensively metabolized by the cytochrome P450 enzymes, primarily 
CYP3A4. Thus, potent inducers or inhibitors of this enzyme may alter the plasma 
concentrations of lurbinectedin. This study is designed to examine the PK and safety of 
lurbinectedin when co-administered with itraconazole, a strong CYP3A4 inhibitor, in 
comparison with lurbinectedin alone. The results of this study may be used to support 
future clinical studies in patients and prescribing information in future labeling.
1.3
PHARMACOGENETIC SUB-STUDY RATIONALE
Germline genetic variants may influence exposure and toxicity (i.e. disposition, 
metabolism and safety) to lurbinectedin. In order to explore the potential impact of 
genetic factors that may account for inter individual variability in the main PK
parameters, blood sample for germline DNA extraction will be collected and stored for 
future pharmacogenetic (PGt) analysis. One blood sample obtained at any time during 
the study, but preferably just before infusion start along withPK sample #1 on Day 1 of 
Cycle will be obtained.

OVERALL STUDY DESIGN
3.1
STUDY DESIGN
This is a prospective, open-label, two-way crossover, phase Ib drug-drug interaction 
study in patients with advanced solid tumors.
The study will include a pre-treatment (screening) phase followed by a treatment phase 
consisting of two lurbinectedin cycles, one cycle in combination with itraconazole and 
one cycle of lurbinectedin as single agent (in different order depending on the study 
sequence), and one additional third cycle of lurbinectedin as a single agent for patients 
who meet the continuation criteria and obtain a clinical benefit after the first two cycles, 
and then follow-up of adverse events if any.
Patients who meet the continuation criteria and obtain a clinical benefit after the first 
two cycles according to the Investigator’s criteria will have the opportunity to continue 
treatment under a Compassionate Use Agreement after the completion of the optional 
third study cycle.
Patients will be treated as outpatients. At the discretion of the Investigator, patients may 
be admitted to the study center on Day –1 or Day 1 and monitored, at least, until 
completion of the Day 1 PK blood sample collections.
Patients will receive a maximum of three cycles: two consecutive cycles of 
lurbinectedin, one cycle with and one cycle without itraconazole co-administration (in 
different order depending on the study Sequence 1 or Sequence 2 of treatment), 
followed by a third cycle with lurbinectedin alone (this last optional for patients with 
clinical benefit). Lurbinectedin will be administered as a 1-hour (-5/+20 min) i.v. 
infusion q3wk via a central or peripheral vein.
In the co-administration cycles, itraconazole will be administered orally once daily in 
the morning after breakfast during 12 consecutive days, self-administered at home from 
Day -4 (i.e., four days before lurbinectedin infusion) until Day 8 (i.e., seven days after 
lurbinectedin infusion), and supplied at the study center on Day 1, following 

CL_0363 3.0
Page 43 of 93
Protocol PM1183-A-018-20
recommendations at the Summary of Product Characteristics (SmPC). On Day 1 (i.e., 
the day of lurbinectedin infusion), itraconazole will be given immediately prior to 
starting the lurbinectedin infusion. In fact, itraconazole should be administered after 
obtaining the itraconazole pharmacokinetic (PK) sample #1 and before the start of 
lurbinectedin infusion (-15 min to -1 min).
In case of lurbinectedin delay (≤ 2 days), itraconazole could be administered during a 
maximum of 14 days.
This study will consist of two parts (Figure 2): Part A and B. The dose of lurbinectedin 
when given in combination with itraconazole for the initial three patients in Part A will 
be 0.8 mg/m², and in Part B is susceptible to be adjusted properly if deemed necessary 
based on exposure and safety experience in Part A. The dose of lurbinectedin during 
Parts A and B will be 3.2 mg/m² for all patients when administered without 
itraconazole. If toxicity occurs, the appropriate intra-patient dose level (DL) reductions 
will be implemented in the subsequent cycle. This DL reduction will be according to
Table 8.

In Part A, three patients will be enrolled to Sequence 1 (TR: Test-Reference) and will
receive itraconazole with lurbinectedin in Cycle 1 followed by two consecutive cycles 
of lurbinectedin alone (the last cycle being optional for patients with clinical benefit
according to the Investigator’s criteria). 
Enrollment for Part A will be sequential. Once the first patient enrolled has completed 
Cycle 1 and Cycle 2, the second and the third patients could be enrolled simultaneously, 
after the evaluation of lurbinectedin total PK parameters, and if no unacceptable or life-
threatening toxicities have occurred for this first patient. However, if toxicity occurs, the 
appropriate dose reductions will be implemented with the second and third patients
based on the PK and safety information of first patient.
The dose of lurbinectedin when given in combination with itraconazole for the initial 
three patients in Part A will be 0.8 mg/m². However, if lurbinectedin exposure in the 
first patient of Part A does not allow an adequate PK assessment, the lurbinectedin dose 
of the following patients may be increased accordingly.
Upon exposure and safety assessments in Part A, the dose of lurbinectedin to be co-
administered with itraconazole in Part B can be readjusted accordingly. This decision 
will be made by the Sponsor and study Investigators.

CL_0363 3.0
Page 44 of 93
Protocol PM1183-A-018-20
Therefore, the planned dose of lurbinectedin, when given with itraconazole for the 
remaining eight patients in Part B will be based on the acceptability of the PK and 
safety results from the first three patients in Part A. If the initial three patients do not 
experience adverse events (AEs) which might require a dose reduction, the dose of 
lurbinectedin may still be adjusted (based on the assumption of dose-proportional 
pharmacokinetics) to produce plasma lurbinectedin AUC values that are comparable to 
those when lurbinectedin is given in the absence of itraconazole. However, if toxicity 
occurs in the initial three patients in Part A, the appropriate dose-reduction of 
lurbinectedin will be implemented in Part B accordingly.
If the safety and PK data obtained from the three patients in Part A is deemed 
acceptable as defined in the protocol, Part B of this study will begin enrollment. 
Therefore, once Part A is completed, patients in Part B will be enrolled based on the 
review of the safety following completion of the first cycle of the previous patient(s),  
and will be randomized in a 1:1 ratio to Sequence 1 (as used in Part A) or Sequence 2 
(RT: Reference-Test; lurbinectedin + itraconazole in Cycle 2). 
In Part A, all patients will receive itraconazole plus lurbinectedin in Cycle 1 and 
lurbinectedin alone in Cycles 2 and 3 (this last cycle being optional).
In Part B, patients will be randomly assigned to the corresponding sequences:

Sequence 1 (TR) (same used in Part A):
o
Cycle 1: Itraconazole + lurbinectedin
o
Cycle 2: Lurbinectedin alone
o
Cycle 3: Lurbinectedin alone (optional)

Sequence 2 (RT):
o
Cycle 1: Lurbinectedin alone
o
Cycle 2: Itraconazole + lurbinectedin
o
Cycle 3: Lurbinectedin alone (optional)
Lurbinectedin will be administered to 11 evaluable patients and for a maximum of three 
cycles, while considered to be on the patient’s best interest or until PD, unacceptable 
toxicity, intercurrent illness of sufficient magnitude to preclude safe continuation of the 
study, patient’s refusal and/or non-compliance with study requirements, a protocol 
deviation with an effect on the risk/benefit ratio of the clinical study, more than two  
lurbinectedin dose reduction due to AEs related to lurbinectedin (unless clear clinical 
benefit has been documented and always with the Sponsor’s agreement) or any other 
reason at the physician’s judgment that precludes lurbinectedin continuation.
If the patient meets the continuation criteria and shows a clear clinical benefit after the 
first two cycles, treatment with lurbinectedin may continue outside this study under a 
Compassionate Use Agreement at the same dose based on Investigator’s decision and 
upon agreement with the Sponsor. Then, the treating center must request authorization 
to the relevant Health Authorities and notify the Sponsor in due time. In order to avoid a 
treatment discontinuation, during the Compassionate Use Agreement authorization an 
additional third cycle with lurbinectedin is allowed.
All adverse events (AEs) will be graded according to the National Cancer Institute 
Common Terminology Criteria for Adverse Events (NCI-CTCAE) v.5. Treatment 
delays, dose reduction requirements and reasons for treatment discontinuation will be 
monitored throughout the study. The safety profile of patients will be monitored 

CL_0363 3.0
Page 45 of 93
Protocol PM1183-A-018-20
throughout the treatment and up to 31 days (±10 days) after the last lurbinectedin
infusion (end of treatment, EOT), until the patient starts a new antitumor therapy or 
until the date of death, whichever occurs first. Any treatment-emergent AEs will be 
followed until recovery to at least grade 1 or stabilization of symptoms or until the start 
of a new antitumor therapy, until the continuation of treatment outside this study under 
a Compassionate Use Agreement or death, whichever occurs first. After treatment 
discontinuation, patients will be followed until resolution or stabilization of all 
toxicities, if any.
Patients will be evaluated at scheduled visits on three study periods: pre-treatment 
(screening), treatment (one cycle of lurbinectedin in combination with itraconazole and 
two as a single agent and the third cycle optional) and follow-up of adverse events if 
any (see Section Schedule of Assessments and Procedures). 
3.2
STUDY DESIGN RATIONALE
Lurbinectedin is a genotoxic agent and should not be administered to healthy subjects. 
Therefore, this study will enroll patients with locally advanced or metastatic solid 
tumors. The crossover design reduces treatment bias and permits intra-subject 
comparisons and control.
The dose of 3.2 mg/m2 of lurbinectedin administered as a 1-hour (-5/+20 min) infusion 
every 3 weeks will be given to patients when they are not given the itraconazole co-
administration. Studies of single-agent lurbinectedin given as same dose regimen have 
shown activity in several tumor types including endometrial cancer, breast cancer, and 
specially SCLC.
In the itraconazole co-administration cycle, the oral administration in the morning after 
breakfast following recommendations at the SmPC will start with self-administration at 
home on Day -4 (four days before lurbinectedin infusion) and until Day 8 (seven days 
after lurbinectedin infusion), and supplied at the study center on Day 1. On Day 1 (day 
of lurbinectedin infusion), itraconazole will be given immediately prior to the start of 
the lurbinectedin infusion. In case of lurbinectedin delay (≤2 days), itraconazole could 
be administered during a maximum of 14 days.
There is a consensus that itraconazole is the most appropriate replacement for 
ketoconazole, given its strong CYP3A4 inhibition, extensive clinical experience in 
drug-drug interaction (DDI) studies and low QTc prolongation potential as well as its 
well-known safety profile [15, 16]. 
Itraconazole safety profile is characterized by mild and transient liver enzymes 
elevations reported in <5% of patients with chronic dosing, with an estimated frequency 
of 1:500.000 for clinically relevant hepatotoxicity [15]. Short-term dosing with 
itraconazole (i.e., ≤14 days), as done in DDI studies, is considered to be associated with 
a very low risk of liver injury compared to chronic treatment. The risk of QTc 
prolongation with itraconazole administration, especially at limited dose (i.e., ≤200 mg 
qd), is low based on in vitro data and clinical experience [15]. The only safety concern 
associated with itraconazole is the risk of decreased cardiac contractility [17]. Thus, 
itraconazole use in patients with ventricular dysfunction or history of heart failure 
should be avoided. Therefore, only patients with left ventricular ejection fraction 
(LVEF) within normal range (according to institutional standards) are allowed to 
participate in the present DDI study.

CL_0363 3.0
Page 46 of 93
Protocol PM1183-A-018-20
The proposed itraconazole regimen is expected to produce sustained inhibition of 
CYP3A4 activity and ABCB1 (P-gp) transport over the entire lurbinectedin PK profile. 
The total daily dose given in a single dose (i.e., 200 mg once daily) on the morning 
during 12 days (8 days after the lurbinectedin infusion start) will produce a consistent 
degree of inhibition of CYP3A4 activity and ABCB1 (P-gp) transport during each day 
of lurbinectedin-itraconazole co-administration [15, 16].
The exposure of lurbinectedin given as a 1-hour i.v. infusion when co-administered with 
itraconazole, a strong CYP3A4 inhibitor, will be assessed. Previously, a dose of 1.3 
mg/m2 administered over 1 hour  without concomitant administration of inhibitors of 
CYP3A4 activity, produced lurbinectedin concentrations in plasma that were 
measurable for at least 160 hours after start of the infusion (FiH study, PM1183-A-001-
08). A 0.8 mg/m2 dose of lurbinectedin co-administered with itraconazole is expected to 
produce measurable concentrations in samples collected for at least the initial 160 
hours. The plasma exposure values of lurbinectedin at 0.8 mg/m2 are not expected to 
exceed those observed following administration of 3.2 mg/m2 of single-agent 
lurbinectedin given over 1 hour since the concomitant administration of aprepitant 
(CYP3A4 moderate inhibitor) decreased the mean plasma clearance of lurbinectedin by 
only 30% (study PM1183-A-008-13).
The PK (and safety) of itraconazole will be assessed sequentially in the first three
patients (Part A) in order to confirm the above statements. The regimen of itraconazole 
used in Part A (12 days 200 mg qd) will be the same as the regiment to be used in Part 
B of the study in order to facilitate the extrapolability of the itraconazole effects on the 
PK (and safety) of lurbinectedin reported in Part A.
Patients will receive i.v. corticosteroids (according to institutional standard antiemetic 
doses, minimum dose of 8 mg/day and maximum dose of 20 mg/day of dexamethasone 
sodium phosphate or equivalent) 30 ± 5 min before the infusion of lurbinectedin during 
Cycles 1 and 2. The optional treatment with additional antiemetic drugs on Day 1 of 
Cycles 1 and 2 is allowed, but should be identical across Cycle 1 and 2 for a given 
patient when possible to minimize intra-subject variability in the PK of lurbinectedin. 
Ondansetron is the recommended serotonin (5-HT3) antagonist, since it is metabolized 
by multiple hepatic cytochrome P450 enzymes. Its metabolic clearance is less likely to 
be influenced by the co-administration of itraconazole, relative to a serotonin receptor 
antagonist that is predominately metabolized by a single cytochrome P450 enzyme.
A 505-hour blood sample collection period is sufficient to assess the potential effects of 
itraconazole on lurbinectedin systemic exposure. In order to confirm the presence of 
measurable itraconazole exposure and provide an abbreviated profile of plasma 
concentrations of itraconazole, six samples will be collected in the cycle during which 
patients receive itraconazole, as detailed in the Schedule of Assessments and Procedures
section. 
3.3
PRIMARY ENDPOINT
3.3.1
Plasma exposure to lurbinectedin
Plasma dose-normalized Cmax and AUC0-∞of lurbinectedin will be compared between 
Cycle 1 and Cycle 2. Pharmacokinetic analyses will be evaluated in plasma by standard 
non-compartmental methods, or population methods, if necessary.

SECONDARY ENDPOINTS
3.4.1
Secondary PK parameters

Differences in dose-normalized total AUC0-t and Cmax and in Cl, Vss and T1/2 of 
lurbinectedin between Cycle 1 and Cycle 2 will be explored.

Differences in dose-normalized unbound AUCu,0-∞, AUCu,0-t and Cu,max and in CLu, 
Vss,u and T1/2,u of lurbinectedin between Cycle 1 and Cycle 2 will be explored.

Differences in ratios between total AUC0-∞, AUC0-t and Cmax, of main lurbinectedin 
metabolites relative to parent drug between Cycle 1 and Cycle 2 will be explored. 
Additional PK parameters will be calculated if deemed appropriate.
3.4.2
Safety Profile
Treatment safety, including AEs, serious adverse events (SAEs) and laboratory 
abnormalities will be graded according to the NCI-CTCAE v.5. Additionally, 
treatment compliance, in particular dose reductions requirements and/or treatment 
delays due to AEs, and reasons for treatment discontinuation will also be described.
Patients will be evaluable for safety if they have received at least one partial or 
complete infusion of lurbinectedin.
3.4.3
Pharmacogenetics
The presence or absence of PGt polymorphisms in genes relevant for lurbinectedin 
disposition (distribution, metabolism and excretion) from a single blood sample 
collected (only if written IC given) at any time during the trial (but preferably at the 
same time as the pre-treatments PK sample on Day 1 of Cycle 1), which will be stored 
to explain individual variability in main PK parameters in future analyses.

participation in the clinical study PM1183-A-018-20.
5.
PLAN OF THE STUDY
5.1
PLANNED STUDY PERIODS (FOR THE WHOLE STUDY)
The total duration of the study will be approximately 22 months, including 
approximately an 18-month enrolment period.

Planned start date (first patient on study): 3Q2020.

Planned enrolment period: approximately 18 months.

Planned end-of-study date (clinical cutoff): 31 (±10) days after the date of the 
last lurbinectedin administration for last patient/last
cycle,
or when 
confirmation of evaluability of at least eight patients in Part B, whichever 
occurs last.
Patients who meet the continuation criteria and obtain a clear clinical benefit 
with lurbinectedin after the completion of the first two study cycles, according 
to the Investigator’s criteria may continue treatment outside this study under a 
Compassionate Use Agreement after the completion of the optional third study 
cycle. Should the patient continue under a Compassionate Use Agreement, the 
treating center must request authorization to the relevant Health Authorities and 
notify the Sponsor in due time.
5.2
PLANNED STUDY PERIODS (INDIVIDUALLY PER PATIENT)
Patients will be evaluated at scheduled visits in three study periods:

Pre-treatment (screening): from signature of the ICF to the day of first 
administration of the study treatment (itraconazole or lurbinectedin).

Treatment: from first administration of the study treatment (itraconazole or 
lurbinectedin) to the last dose of lurbinectedin plus 31 days (end-of-treatment, 
EOT) (maximum of three cycles).

CL_0363 3.0
Page 50 of 93
Protocol PM1183-A-018-20

Follow-up of adverse events: after EOT, patients with treatment-related 
toxicities > grade 2 will be followed  every four weeks until recovery to at least 
grade 1 or stabilization of all treatment-emergent AEs, or until the start of a new 
antitumor therapy, until the continuation of treatment outside this study under a 
Compassionate Use Agreement or death, whichever occurs first. 
Patients will be considered to be on-study from the signature of the ICF to the end of 
the follow-up period. Patients will be considered to be on-treatment for the duration of 
their treatment and until the day of EOT, immediately before the start of the follow-up 
period. 
An end-of-treatment visit will be performed within 31 days (±10 days) after 
administration of the last dose of lurbinectedin, unless the patient dies or starts any new 
antitumor therapy outside this clinical study, in which case the EOT visit should be 
performed immediately before the start of the new therapy (ideally the day before or the 
same day).
5.2.1
Discontinuations
5.2.1.1 Treatment Discontinuation
Treatment discontinuation occurs when an enrolled patient ceases to receive the study 
treatment regardless of the circumstances. By convention, the date of EOT is defined as 
31 days after the day of the last dose of lurbinectedin (treatment discontinuation), the 
start of a new antitumor therapy or death, whichever occurs first, in which case the date 
of administration of this new therapy or the date of death will be considered the date of 
EOT.
The primary reason for any treatment discontinuation will be recorded on the patient’s 
electronic Case Report Form (eCRF).
If a patient discontinues treatment, every effort should be made to complete the 
scheduled assessments as appropriate.
5.2.1.2 Reasons for Treatment Discontinuation
Patients will receive the study medication for a maximum of three cycles and while it is 
considered to be in their best interest. Specifically, treatment will continue for a 
maximum of three cycles until:

Disease progression.

Unacceptable toxicity.

Intercurrent illness of sufficient magnitude to preclude safe continuation of the 
study.

Patient’s refusal and/or non-compliance with study requirements.

A protocol deviation with an effect on the risk/benefit ratio of the clinical 
study.

Delay > 14 days due to treatment-related adverse events (unless clear clinical 
benefit has been documented and always with the Sponsor’s agreement).More 
than two lurbinectedin dose reductions due to adverse events related to 
lurbinectedin (unless clear clinical benefit has been documented and always 
with the Sponsor’s agreement).

CL_0363 3.0
Page 51 of 93
Protocol PM1183-A-018-20

Any other reason at the physician’s judgment that precludes lurbinectedin 
continuation. 
5.2.1.3 Study Discontinuation
Study discontinuation occurs when an enrolled patient ceases to participate in the study, 
regardless of the circumstances, prior to completion of the study. Patients have the right 
to withdraw consent at any time; if this is the case, no further study procedures should 
be performed. The Investigator must determine the primary reason for discontinuation. 
The date and reason for a patient’s discontinuation from the study will be recorded on 
the eCRF.
5.2.2
Protocol Deviations
A protocol deviation is defined as any departure from what is described in the protocol 
of a clinical study approved by an Independent Ethics Committee (IEC) and a 
Competent Authority. Therefore, it applies to deviations related to patient inclusion and 
clinical procedures (e.g., assessments to be conducted or parameters to be determined), 
and also to other procedures described in the protocol that concern Good Clinical 
Practice (GCP) guidelines or ethical issues (e.g., issues related to obtaining patients’ 
informed consent, data reporting or Investigator’s responsibilities).
Deviations with no effects on the risk/benefit ratio of the clinical study (such as minimal 
delays in assessments or visits) will be distinguished from those that might have an 
effect on this risk/benefit ratio, such as:

Deviations that might affect the clinical study objectives, such as those involving 
relevant inclusion/exclusion criteria (which could mean that the patient is not 
eligible for the study) and those having an effect on patient evaluability.

Deviations that might affect the patient’s well-being and/or safety, such as an 
incorrect dosing of study treatment due to not following dose adjustment 
specifications or an incorrect preparation of the medication.

Deviations related to the following of GCP guidelines as described in the protocol 
and regulations in force, such as deviations when obtaining informed consent or 
not following the terms established for reporting serious adverse events (SAEs), 
etc.
No deviations that may have an effect on the risk/benefit ratio of the clinical study will 
be authorized. All protocol deviations detected during the study will be appropriately 
documented, and those considered particularly relevant (i.e., those related to ethical 
issues, fulfillment of GCP guidelines and with an effect on the risk/benefit ratio) will be 
notified to the pertinent IEC and, if applicable, to the Competent Authorities as 
established by local regulations.
5.3
REPLACEMENT OF PATIENTS
Patients must be replaced if they are not evaluable for the assessment of the primary 
endpoint (e.g., if they have not sufficient and interpretable PK parameters). 
Evaluable patients for Part A should have completed sufficient study procedures until 
Day 8 of Cycle 1 (i.e., most itraconazole administration and PK assessments). Evaluable 
patients for Part B for the main objective of the study (e.g., assessment of lurbinectedin 
PK) should have provided sufficient and interpretable PK parameters (e.g., AUC0-t

CL_0363 3.0
Page 52 of 93
Protocol PM1183-A-018-20
should cover at least 80% of AUC0-∞) of Cycle 1 and 2. Evaluable patients should have 
received the first two complete cycles regardless dose delays or reductions. 
For Part A and Part B, the compliance of itraconazole will be confirmed based on a 
patient’s diary, the drug accountability and the expected individual plasma 
concentration at the steady state.
Any replacement patient during the treatment phase will be given a new patient number 
and assigned to the same sequence as the not-evaluable patient being replaced. All 
replaced patients who received the study treatment were to be included in the general 
safety.
6.
STUDY ASSESSMENTS AND PROCEDURES
6.1
ELIGIBILITY ASSESSMENTS  
The patient will be allocated a patient number in the eCRF after signing the ICF and 
screening for eligibility begins. This patient number should be used on all future 
documentation and correspondence referring to this patient. During the screening 
period, the Investigator will assess the patient’s eligibility for inclusion in the study by 
conducting the assessments summarized below (Table 4).

6.2
PATIENT REGISTRATION
Eligibility will be checked before registration confirmed by the Sponsor. The patient 
will be a screening failure if not all inclusion criteria are met, if any exclusion criterion 
is met, or if the Sponsor does not approve registration. Regardless of circumstances, 
Investigators will not be allowed to treat any patient before appropriate receipt of the 
Sponsor’s agreement to proceed with registration. A patient should only be treated if 
eligibility criteria are still met according to assessments performed closest to first drug 
administration.
A patient who has been treated without the Sponsor’s agreement may not be considered 
evaluable for the primary endpoint of the study and may need to be replaced (although 
can continue in treatment provided this does not pose a risk to the patient until 
discontinuation for any other reason).
For patients included in the study (all registered patients) but never treated, only 
baseline and off-study visit modules of the eCRF should be completed but serious 
adverse events (SAEs) occurring during screening need to be reported (using paper SAE 
forms).
For screen failures (patients who started screening but were not finally registered), only 
the screening form of the eCRF should be completed but SAEs occurring during 
screening need to be reported (using paper SAE forms).
6.3
PATIENT RANDOMIZATION
This is an open-label study; therefore, blinding of treatment will not be performed.
Block randomization will be used to avoid bias in the assignment of patients to 
treatment sequence group, to increase the likelihood that known and unknown subject 
attributes (e.g., demographic and baseline characteristics) are evenly balanced across 
treatment sequence groups, and to enhance the validity of statistical comparisons across 
treatment sequence groups. Randomization will apply for study Part B only.
6.4
EVALUATIONS DURING TREATMENT
The following assessments will be done while patient is on treatment (Table 5). For a 
more graphic display, please refer to the table Schedule of Assessments and Procedures.

EVALUATIONS AT THE END OF TREATMENT
The end-of-treatment (EOT) visit will be scheduled within 31 days (±10 days) after 
administration of the last dose of lurbinectedin, unless the patient starts a subsequent 
antitumor therapy, in which case the end-of-treatment visit should be performed 
immediately before the start of the new therapy (ideally the day before or the same day).
Patients who meet the continuation criteria and obtain a clear clinical benefit with 
lurbinectedin after the completion of the first two study cycles, may continue treatment 
outside this study under a Compassionate Use Agreement after the completion of the 
optional third study cycle. Should the patient continue under a Compassionate Use 
Agreement, the treating center must request authorization to the relevant Health 
Authorities and notify the Sponsor in due time. Patients, regardless of the reason for 
ending the treatment, will have to undergo at the end of treatment the following 
assessments:

Complete physical examination (BSA and height not needed).

ECOG PS.

Laboratory tests (hematology and biochemistry A and B, and Calculated CLcr).
Calculated CLcr [Cockcroft and Gault’s formula] should be provided only if 
serum creatinine levels are above ULN.

Coagulation (INR) will be repeated only if clinically indicated.

ECG (in triplicate).

LVEF assessment will be repeated only if clinically indicated.

Adverse Events.

Intercurrent events, concomitant disease and therapies.

Pregnancy test in WOCBP.
Adverse events must be reported for 31 days after the last study treatment 
administration. All serious adverse events (SAEs) occurring within 31 days of the last 
study treatment administration or until the start of a new antitumor therapy, until the 
continuation of treatment outside this study under a Compassionate Use Agreement or 
death, whichever occurs first, will be reported. Beyond this period of time, only those 
suspected to be treatment-related SAEs will be reported (Section 8.5.2).
The Sponsor will evaluate all safety information that is spontaneously reported by an 
Investigator beyond the time frame specified in the protocol.
6.6
FOLLOW-UP AFTER END OF-TREATMENT VISIT
After EOT, patients with treatment-related toxicities > grade 2 will be followed  every 
four weeks until recovery to at least grade 1 or stabilization of all treatment-emergent 

CL_0363 3.0
Page 60 of 93
Protocol PM1183-A-018-20

Corticosteroids i.v. (according to institutional standard antiemetic doses, 
minimum dose of dexamethasone 8 mg/day and maximum dose of 20 mg/day 
of dexamethasone or equivalent). If feasible, the medication and dose 
administered in Cycle 1 should be maintained in Cycle 2.

Serotonin (5-HT3) antagonists (ondansetron at least 8 mg i.v. and no more than 
16 mg of ondansetron).
If necessary, in addition to the above, the duration of treatment with 5-HT3 antagonists 
and/or dexamethasone could be extended orally (if needed) (i.e., 4-8 mg/day for three 
consecutive days) and/or 10 mg of metoclopramide orally every eight hours could be 
added (according to institutional guidelines).
For the purpose of safety evaluations, optimum prophylaxis is defined as all the 
aforementioned medications at their respective maximum dose.
Aprepitant or any other NK-1 antagonist or related Substance P-antagonists 
(except rolapitant) are forbidden while on lurbinectedin treatment.
7.4
CRITERIA FOR TREATMENT CONTINUATION 
Patients may continue treatment with lurbinectedin as long as no unacceptable toxicity 
and/or PD occurred, and for a maximum of three cycles. Thereafter, treatment with 
lurbinectedin can continue under a Compassionate Use Agreement.
In Part A and Part B, patients assigned to Sequence 1 (TR) (lurbinectedin + 
itraconazole in Cycle 1), after Cycle 1 the administration of a new cycle should be 
delayed if the criteria in Table 7 are not met on the corresponding Day 1. Re-
assessments will be performed periodically at intervals of at least 72 hours but not more 
than one week. Lurbinectedin administration should be delayed until recovery of these 
parameters. A maximum delay of 14 days from the theoretical due date will be allowed 
for recovery from treatment-related AEs. If recovery has not occurred after that period, 
the patient should discontinue the treatment, except in case of obvious patient benefit at 
the criteria of the Investigator and upon agreement with the Sponsor.
In Part B, patients assigned to Sequence 2 (RT) (lurbinectedin + itraconazole in 
Cycle 2), criteria for treatment continuation should be investigated on Day 15 of Cycle 
1 in order to confirm itraconazole administration start on Day -4 of Cycle 2, assuring 
that the continuation criteria will be finally met on Day 1 of Cycle 2 assessment. In 
case of detected abnormalities on Day 15 in sequence RT, these assessments should be 
repeated every 48-72 hours until recovery to retreatment criteria. Initiation of 
itraconazole will be delayed for a maximum of 14 days to ensure that pre-treatment 
with itraconazole is fulfilled. If recovery has not occurred after that period, the patient 
should discontinue the treatment, except in case of obvious patient benefit at the 
criteria of the Investigator and upon agreement with the Sponsor.
Re-treatment criteria for lurbinectedin administration should be met on Day 1 of Cycle 
2.
Any patient having any grade ≥ 3 laboratory abnormalities and/or treatment-related 
AEs after Cycle 2 or Cycle 3 is suggested to have the relevant tests re-assessed at 
intervals of at least 72 hours but not more than one week.
If they were not met, treatment will be delayed for a maximum of 2 days to evaluate 
continuation of lurbinectedin administration, with re-treatment criteria being checked 
every 24 hours. During this time the patient will continue receiving itraconazole. If 

CL_0363 3.0
Page 61 of 93
Protocol PM1183-A-018-20
after 2 days of delay the patient does not meet the criteria for treatment continuation, 
itraconazole will be stopped and the patient will be considered not evaluable for the 
trial.
If the criteria for treatment continuation are not met as described above, treatment must 
be discontinued and the EOT visit performed.

Protocol PM1183-A-018-20

Contraceptives.
7.6.2 Prohibited Medications/Therapies

Concomitant administration of any other antineoplastic therapy. 

Any other investigational agents.

Immunosuppressive therapies other than corticosteroids for antiemetic 
prophylaxis, pain control, or low-dose replacement in patients requiring this 
approach. 

Aprepitant or any other NK-1 antagonist or related Substance P-antagonists 
(except rolapitant).

Primary G-CSF prophylaxis.

CYP3A4 inhibitors such as ketoconazole, fluconazole, voriconazole, 
telithromycin, clarithromycin, erythromycin, nafcillin, aprepitant, fosaprepitant, 
verapamil, modafinil, nefazodone, or grapefruit juice.

CYP3A enzyme inducers and/or inhibitors (unless strictly necessary and when 
there is no therapeutic alternative treatments) (see Appendix 3).

Use of any prescription or non-prescription herbal and/or dietary supplements 
within 14 days prior to the first dose of study medication and until 31 days after 
the last administration of lurbinectedin, unless the Investigators, with the 
Sponsor agreement, consider it will not interfere with study procedures of 
patient safety.
7.6.3 Drug-Drug Interactions
In vitro studies with human microsomes have shown that CYP3A4 is the major CYP 
isoform involved in the metabolism of lurbinectedin. The estimated contribution of the 
other CYP isoenzymes to the lurbinectedin metabolism is considered to be negligible. 
Therefore, concomitant drugs which induce or inhibit any of these cytochromes, 
especially CYP3A4, should be carefully monitored or avoided, whenever is possible.
A potentially significant interaction with aprepitant is suggested by available phase II 
data from ovarian cancer patients and phase I data from the PM1183-A-008-13 study. 
Lurbinectedin clearance was reduced by around 30%, approximately, in the presence of 
aprepitant. Although all patients eventually recovered, the use of aprepitant is currently 
forbidden in all phase II/III lurbinectedin studies.
7.7
DRUG ACCOUNTABILITY
The head of the medical institution at each study site (or center) will be the person 
ultimately responsible for drug accountability at the site. The head of the trial site will 
appoint the designee as product storage manager and delegate the control of and 
accountability for the trial drug to him/her. After receipt of the investigational product, 
he/she will keep records to allow a comparison of quantities of drug received and used 
at each site for monitoring purposes.
The investigator or designated study personnel will maintain a log of all itraconazole 
drug dispensed and returned. Drug supplies for each patient will be inventoried and 
accounted for throughout the study.

CL_0363 3.0
Page 64 of 93
Protocol PM1183-A-018-20
All unused drug supplied by the Sponsor will be properly destroyed at the study site. 
Documentation of this procedure must be provided to the Sponsor (or its designee). If 
the Sponsor (or its designee) agrees, unused drug supplies may be returned to the drug 
repository.
7.8
TREATMENT COMPLIANCE
Lurbinectedin will be administered as an i.v. infusion by qualified staff.
The morning doses of itraconazole should be administered after breakfast following the 
SmPC specifications. Patients will self-administer the morning daily doses of 
itraconazole when not at the study center. The study center will contact the patients (via 
telephone or other methods) to remind them or confirm that they have taken the 
morning dose of itraconazole when they are not at the study center. When the patient is 
at the study center, the administration itraconazole is to be supervised and documented 
by the staff. Patients will be requested to keep records of itraconazole when 
administered at home. The patients will be given a diary to record the dates and times 
itraconazole when was administered at home. Diaries will be reviewed at each study 
visit and recorded in the source data system.

STUDY EVALUATIONS
8.1
PHARMACOKINETIC EVALUATIONS
8.1.1 Pharmacokinetic Sample Collection and Handling
Serial peripheral venous blood samples for determination of lurbinectedin (total and 
unbound), lurbinectedin metabolites (i.e., M1 and M4) and itraconazole (as well as, its 
active metabolite, hydroxy-itraconazole) plasma concentrations will be collected at the 
time points indicated in Table 9 and also in the Schedule of Assessments and 
Procedures. The exact dates and times of blood sample collection must be recorded in 
the eCRF.
PK sampling for lurbinectedin will be done always in Cycle 1 and Cycle 2 with a 
schedule of thirteen samples in all patients. PK sampling for itraconazole and hydroxy-
itraconazole will be done in Cycle 1 of Part A and Part B Sequence 1 (TR), and in Cycle 
2 of Part B Sequence 2 (RT) with a schedule of six samples in all patients (Table 9).
Plasma samples for PK analysis of lurbinectedin and itraconazole will be obtained 
through a peripheral vein located in the contra-lateral side to that of the administration 
of lurbinectedin. In any case, the sampling vein has to be different to that in which drugs 
are being administered. Even the last sample must never be collected from the catheter 
used for the drug administration. 
If the blood sample is obtained from a catheter, the first milliliter (mL) of blood will be 
discarded to avoid the dilution of the sample with the solution used to keep it clean. 
Heparin (10 U/mL in normal saline solution) or a slow drip of normal saline solution 
(10 mL/h) can be used to keep the catheter permeable between extractions.
The laboratory manual provides further information regarding handling and shipment of 
plasma samples. Samples will be stored at –80 (±10) ºC.

8.1.2 Analytical Procedures
HPLC-MS/MS determinations of total, unbound plasma concentrations of lurbinectedin 
and total plasma concentration of its main metabolites (i.e., M1 and M4) will be 
performed using validated assays. 
A validated bioanalytical method will be used to measure the itraconazole and hydroxy-
itraconazole plasma concentrations.
8.1.3 Pharmacokinetic Parameters
The time course of metabolite concentration –relative to parent drug, and if possible, 
absolute– will be elucidated up to the maximum possible extent, to obtain the best 
available estimate for metabolite exposure. 
Total and unbound plasma concentration time course of the lurbinectedin and its main 
metabolites will be analyzed by standard non-compartmental methods. Itraconazole 
total plasma concentration time course also will be analyzed by standard non-
compartmental methods. The area under the concentration-time curve (AUC) will be 
calculated using the linear-log trapezoidal rule with extrapolation to infinity. The 
maximum plasma concentration (Cmax) will be obtained directly from the experimental 
data. Terminal half-life (T1/2) will be obtained from the terminal rate constant calculated 
by linear regression using at least 3 observations. Other parameters will be calculated 
including: 
Mean residence time extrapolated to infinity (MRT) corrected by the infusion time. 
It is calculated by dividing the area under the moment curve extrapolated to infinity by 

CL_0363 3.0
Page 66 of 93
Protocol PM1183-A-018-20
the area under the curve extrapolated to infinity and subtracting half the duration of drug 
infusion.
Total body clearance (CL), calculated by dividing the administered dose by the AUC 
with extrapolation to infinity.
Volume of distribution (both at steady state and based on the terminal phase) (Vss and 
Vz, respectively): Vss is an estimate that equals mean residence time times total body 
clearance. Vz, calculated dividing the administered dose by the product of the AUC with 
extrapolation to infinity by the terminal rate constant.
The same analysis will be applied to the metabolites for which the obtained 
experimental data allow it. The potential relevance of the identified metabolites will be 
explored by additional preclinical experiments that will be decided on the basis of the 
results and, if possible, by opportunistic observations based on the study data. 
8.2
PHARMACOGENETICS
Patients will be evaluable for pharmacogenetics if they have signed the ICF and a valid 
9-mL blood sample will be taken for genetic analysis at any time during the study, but 
preferably before infusion start along with PK sample #1 on Day 1 of Cycle 1. 
A genotype evaluation in genes relevant for lurbinectedin metabolism and transport will
be investigated and reported in an independent report in order to determine whether the 
observed differences between patients in PK parameters are related to these genetic 
features.
8.3
SAFETY
Patients will be evaluable for safety if they have received at least part of one 
lurbinectedin infusion. AEs will be graded according to the NCI-CTCAE v. 5.
Treatment compliance, i.e., dose delays, dose reductions and reasons for treatment 
discontinuation, will be monitored throughout the study. 
The safety profile of patients will be monitored throughout the treatment and up to 31 
days (±10 days) after the last treatment infusion (EOT), or until the patient starts a new 
antitumor therapy, until the continuation of treatment outside this study under a 
Compassionate Use Agreement or until the date of death, whichever occurs first.
Any treatment-emergent AEs will be followed until recovery to at least grade 1 or 
stabilization of symptoms or until the start of a new antitumor therapy, until the 
continuation of treatment outside this study under a Compassionate Use Agreement or 
death, whichever occurs first. After treatment discontinuation, patients will be followed 
until resolution or stabilization of all toxicities, if any. Patients having any treatment-
related grade ≥ 3 AEs should have relevant tests re-assessed at intervals of at least 72 
hours but not more than one week (for patients allocated to Sequence 1) at least every 
48-72 hours (for patients allocated to Sequence 2) until recovery to at least grade 2.

ADVERSE EVENT DEFINITIONS
8.4.1 Adverse Event
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product which does not necessarily have a causal 
relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign, (e.g., an abnormal 
laboratory finding), or a disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Illnesses with onset during the study or exacerbations of pre-existing illnesses, including
but not limited to clinically significant changes in physical examination findings and 
abnormal objective tests/procedures findings (e.g., X-ray, ECG) should be recorded. 
The criteria for determining whether an abnormal objective test finding should be 
reported as an AE are as follows:

The test result is associated with clinically significant symptoms, and/or

The test result leads to a change in the study dosing or discontinuation from the 
clinical trial, significant additional concomitant drug treatment or other therapy, 
and/or

The test result leads to any of the outcomes included in the definition of a SAE 
(see definition below), and/or

The test result is considered to be clinically relevant by the Investigator.
For the purpose of this protocol, PD or worsening of the underlying malignancy should 
not be reported as AEs.
8.4.2 Serious Adverse Event 
A SAE is defined as any adverse experience occurring at any dose that:

results in death (is fatal),

is life-threatening,

requires or prolongs inpatient hospitalization,

results in persistent or significant disability or incapacity,

is a congenital anomaly or birth defect, or

is medically significant.

Any suspected transmission via a medicinal product of an infectious agent.
Medical and scientific judgment should be exercised in deciding whether expedited 
reporting is appropriate in other situations, such as an important medical event that may 
not be immediately life-threatening or result in hospitalization but may jeopardize the 
patient or may require intervention to prevent one of the outcomes listed in the above 
definition.
Tumor progression (including associated signs and symptoms) or appearance of new 
tumor lesions cannot be reported as a SAE.

CL_0363 3.0
Page 68 of 93
Protocol PM1183-A-018-20
8.4.3 Death
Death as such is the outcome of a SAE and should not be used as the SAE term itself. 
The cause of death should be recorded as the SAE term instead. When available, the 
autopsy report will be provided to the Sponsor.
8.4.4 Life Threatening Event
A life threatening event is defined as any event in which the subject is at risk of death at 
the time of the event; it does not refer to an event which hypothetically might have 
caused death if it were more severe.
8.4.5 Hospitalization/Prolongation of Hospitalization
Any event requiring hospitalization (or prolongation of hospitalization) that occurs or 
worsens during the course of a patient’s participation in a clinical study must be 
reported as a SAE unless exempted from SAE reporting. Prolongation of hospitalization 
is defined as any extension of an inpatient hospitalization beyond the stay 
anticipated/required for the initial admission, as determined by the Investigator or 
treating physician.
Hospitalizations that do not meet criteria for SAE reporting are: 

Reasons described in the protocol (e.g., investigational medicinal product 
administration, protocol-required investigations). However, events requiring 
hospitalization or prolongation of hospitalization as a result of a complication 
of therapy administration or clinical study procedure will be reported as a SAE.

Hospitalization or prolonged hospitalization for technical, practical or social 
reasons, in the absence of an AE. 

Pre-planned hospitalizations: Any pre-planned surgery or procedure must be 
documented in the source documentation. Only if the pre-planned surgery 
needs to be performed earlier due to a worsening of the condition, should this 
event (worsened condition) be reported as a SAE.
Other situations that MUST NOT be considered as hospitalizations are:

An emergency visit due to an accident where the patient is treated and 
discharged.

When the patient is held 24 h for observation and is finally not admitted.

Planned treatments at sites not associated to a hospital and generally considered 
as minor surgical procedures (i.e. laser eye surgery, arthroscopy, etc…).
8.4.6 Unexpected/Unlisted Adverse Event
An AE is considered unexpected/unlisted when the nature or severity of which is not 
consistent with the applicable reference safety information. The Sponsor will use as 
reference safety information for the evaluation of listedness/expectedness the most 
updated IB for lurbinectedin, and the SmPC for commercially-available itraconazole.

CL_0363 3.0
Page 69 of 93
Protocol PM1183-A-018-20
8.4.7 Adverse Reaction
All untoward and unintended response to an IMP related to any dose administered. This 
definition also covers medication errors and uses outside what is foreseen in the 
protocol, including overdose, misuse and abuse of the product. 
8.4.8 Adverse Events Related to the Study Drug
An AE is considered related to a study drug/IMP if the Investigator's and/or the 
Sponsor’s assessment of causal relationship to the IMP(s) is "Y (yes)" (See section 
8.4.10). The Investigator will assess the causal relationship of the IMP(s) to the SAE. 
The Sponsor may also consider related to the study drug(s)/IMP(s) those events for 
which the Investigator assesses the causal relationship with the IMP(s) as "UK 
(unknown)" when it cannot rule out a role of the IMP(s) in the event.
8.4.9 Expedited Reporting
The Sponsor is responsible for appropriate expedited reporting to the Competent 
Authorities, the Investigators and the IEC according to current legislation.
8.4.10 Assessment of Causal Relationship to the Study Drug
The Investigator must provide an assessment of causality for the IMP according to the 
following criteria:

Y (yes): there is a reasonable possibility that the IMP(s) caused the SAE.

N (not): there is NO reasonable possibility that the IMP(s) caused the SAE and 
other causes are more probable.

UK (Unknown): only to be used in special situations where the Investigator has 
insufficient information (i.e., the patient was not seen at his/her center). If none 
of the above can be used. 
8.5
ADVERSE EVENT REPORTING PROCEDURES
8.5.1 Reporting of Adverse Events
The Sponsor will collect AEs until 31-day (±10 days) after administration of the last 
dose of lurbinectedin or until the start of a new antitumor therapy, until the continuation 
of treatment outside this study under a Compassionate Use Agreement or until the date 
of death, whichever occurs first. All AEs suspected to be related to the study 
drug(s)/IMP(s) must be followed-up after the time of therapy discontinuation until the 
event or its sequelae resolve or stabilize at an acceptable level to the Investigator and 
the Sponsor.
All AEs, including medication errors and uses outside what is foreseen in the protocol, 
must be recorded in English using medical terminology in the source document and the 
eCRF. Whenever possible, the Investigator will record the main diagnosis instead of the 
signs and symptoms normally included in the diagnoses. 
Investigators must assess severity (grade) of the event following the NCI-CTCAE v.5 
and assign a relationship to each study drug(s)/IMP(s); and pursue and obtain 
information adequate both to determine the outcome and to assess whether it meets the 
criteria for classification as a SAE requiring immediate notification to the Sponsor or its 

CL_0363 3.0
Page 70 of 93
Protocol PM1183-A-018-20
designated representative. The Investigator must provide any relevant information as 
requested by the Sponsor in addition to that on the eCRF.
Abnormal laboratory tests occurring during the study must only be recorded in the AE 
section of the eCRF if the disorder:

Is associated with clinically significant symptoms, and/or

Leads to a change in study dosing (omission, delay or reduction) or discontinuation 
from the study, significant additional concomitant drug treatment or other therapy, 
and/or

Leads to any of the outcomes included in the definition of a SAE.
Otherwise, laboratory results should be reported in the corresponding section of the 
eCRF (e.g. biochemistry, hematology).
8.5.2 Reporting of Serious Adverse Events
The Sponsor will collect SAEs from the time of signing of the ICF and until 31 (±10)
days after administration of the last dose of lurbinectedin or until the start of a new 
antitumor therapy, until the continuation of treatment outside this study under a 
Compassionate Use Agreement or death, whichever occurred first. Beyond this period 
of time, only those SAEs suspected to be related to the IMPs will be collected. 
Nonetheless, the Sponsor must evaluate any safety information related to the clinical 
study that is spontaneously reported by an Investigator beyond the time frame specified 
in the protocol.
All SAEs (as defined above) that have occurred after patient registration, regardless of 
relationship to the study drug(s)/IMP(s), must be reported immediately, and always 
within 24 hours to the Pharma Mar S.A. Pharmacovigilance Department electronically 
by completing the applicable eCRF section. Only in situations of electronic system 
failure or pregnancy exposure during the clinical trial, can SAEs be reported using paper 
on a “SAE form by fax (+34 91 846 6004), e-mailAEincoming@pharmamar.com) or 
telephone (+34 91 823 4562). Out of office hours [Greenwich Meridian Time (GMT)], 
assistance on SAE reporting can be obtained by calling the Pharmacovigilance 
Department at +34 681 263 592. In case of electronic system failure or pregnancy 
exposure during the clinical trial, SAEs initially reported by alternative methods (not 
electronically), must be followed by a completed electronic SAE reporting on eCRF 
from the investigational staff within one working day.
SAEs occurring during the screening phase (from ICF signature to the first study drug 
administration) and after off-study will be reported using a paper “SAE form” that must 
be forwarded as mentioned above always within 24 hours to the Pharma Mar S.A. 
Pharmacovigilance Department by fax or email.
All SAEs suspected to be related to the study drug must be followed until the event or 
its sequelae resolves or stabilizes to at least grade 1, or to an acceptable level according 
to the Investigator and the Sponsor or his/her designated representative.
8.5.3 Reporting of Pregnancy Cases Occurring During the Clinical Study
National regulations require that the Sponsor collect information on pregnancies 
occurring during clinical trials, in which exposure to the study drug at any time during 
pregnancy, via either maternal or paternal exposure, is suspected. 

CL_0363 3.0
Page 71 of 93
Protocol PM1183-A-018-20
Therefore, pregnancy and suspected pregnancy (including a positive pregnancy test 
regardless of age or disease state) of a female patient or the female partner of a male 
patient occurring while the patient is on study drug, or within 31 days of the patient’s 
discontinuation visit, are considered an immediately reportable events.
The investigator will report the following events immediately and always within 24 
hours from first knowledge:

Any occurrence of a pregnancy where any kind of exposure to the study drug is 
suspected.

Possible exposure of a pregnant woman.

All reports of elevated/questionable or indeterminate beta human chorionic 
gonadotropins (β-hCGs).
Immediately after detecting a case of suspected pregnancy in a female clinical trial 
patient, the decision on her continued participation in the clinical trial will be jointly 
taken by the trial patient, the Investigator and the Sponsor with the patient’s best interest 
in mind. A decision to continue the pregnancy will require immediate withdrawal from 
the trial.
Any pregnancy, suspected pregnancy, or positive pregnancy test must be reported to the 
Pharmacovigilance Department at PharmaMar immediately by facsimile using the 
Pregnancy Report Form.
The Investigator will follow the pregnancy until completion/termination, and must 
notify the outcome of the pregnancy to the Pharmacovigilance Department at
PharmaMar within 24 hours of first knowledge as a follow-up to the initial Pregnancy 
report.
For any event during the pregnancy which meets a seriousness criterion (including fetal 
or neonatal death or congenital anomaly), the Investigator will also follow the 
procedures for reporting SAEs (complete and send the SAE form to Sponsor,  
Pharmacovigilance by facsimile within 24 h of the Investigator’s knowledge of the 
event).
All neonatal deaths that occur within 30 days of birth should be reported, regardless of 
causality, as SAEs. In addition, any infant death at any time thereafter that the 
Investigator suspects as related to the in utero exposure to the study drug should also be 
reported to the Pharmacovigilance Department at PharmaMar by facsimile within 24 h 
of the Investigators’ knowledge of the event. 
8.6
ADVERSE EVENTS MONITORING
Safety review will be performed at Pharma Mar, S.A. once the SAE forms have been 
received and the eCRFs have been completed by the Investigator. 
Periodic safety review of clinical data will be performed; however, no formal Data 
Safety Monitoring Board has been appointed for this trial. AEs will be monitored by the 
Investigators and by the study team at Pharma Mar, S.A. The personnel in charge of this 
process are defined in the section “Study Contacts” of this protocol. In general, a 
clinical oncologist, together with a member of the Pharma Mar, S.A. Pharmacovigilance 
Department will review the safety data of this trial on an ongoing basis. 

CL_0363 3.0
Page 72 of 93
Protocol PM1183-A-018-20

SAEs will be collected, assessed and reported as per the applicable Regulations 
by the Pharmacovigilance Department. 
Non-serious AEs will be checked for accuracy against the eCRF during monitoring 
visits by the monitor. 
8.7
EFFICACY
Not applicable.
9.
STATISTICAL METHODS
This clinical pharmacology study is designed to assess the impact of itraconazole co-
administration on lurbinectedin PK parameters administered alone.
9.1
ANALYSIS POPULATIONS
The PK population will include all patients enrolled in Part A and B who have sufficient 
and interpretable PK parameters to calculate the non-compartmental PK parameters. 
Only the patients in Part B who have completed the two cycles and have sufficient and 
interpretable PK assessments will be included in the statistical comparison to assess the 
effect of itraconazole on the PK of lurbinectedin.
The safety population will include all patients who received at least one dose of 
lurbinectedin. Patients who have received at least one dose of itraconazole but who did 
not receive any dose of lurbinectedin will be excluded from the safety population. The 
analysis of data from these patients will be performed separately (e.g., by means of 
narratives). The safety population will be used for all safety evaluations.
9.2
SAMPLE SIZE
A block randomization (1:1 ratio) will be performed only in Part B. At least 11 patients 
(three patients in Part A followed by eight patients in Part B) are expected to complete 
all study procedures, including the collection of sufficient and interpretable PK 
assessments. Although at least 11 patients will be enrolled in this study; it is estimated 
that complete data from eight patients will be sufficient to estimate the drug-drug 
interaction of itraconazole on the PK of lurbinectedin. In case of patient replacement, a 
new patient number will be provided and he/she will be assigned to the same sequence 
as the patient being replaced.
This study was designed to assess the potential effects of itraconazole on the PK of 
lurbinectedin in patients with advanced malignancies. The 90% CI will be used to help 
with the interpretation of the results. A sample size of eight patients was based on 
feasibility and clinical considerations. Based on previous studies, the intra-subject 
coefficient of variation (CV) of lurbinectedin PK parameters is estimated to be more 
than 30%. The precision (half-width) of the 90% CI for [(lurbinectedin + itraconazole) / 
lurbinectedin alone] comparison on the log-scale will extend 0.389 from the observed 
differences in means, assuming that the intra-subject CV around 40%. This half-width 
corresponds to a 90% CI in the range of 70% and 147% assuming the ratio of the means 
equal to unity for each PK parameter. This 90% CI will be used to help with the 
interpretation of the results.

9.3
STATISTICAL ANALYSIS
Descriptive statistics (arithmetic and geometric means, median, SDev, CV% and 95% 
confidence interval [CI], range of value, frequencies and percentages) will be used to 
summarize the data.
9.3.1 Demographics
Descriptive statistics will be used to summarize the patients’ baseline characteristics.
9.3.2 Safety
All AEs will be graded according to NCI-CTCAE v.5. 
Treatment-emergent adverse events (TEAEs) are any adverse event aggravated in 
severity from baseline or having their onset between the first dose of the study drug and 
31-day (±10 days) after the last treatment dose, death or date of further therapy, 
whichever came first. AEs related to the study treatment or with unknown relationship 
occurring more than 31 days after the last dose were also taken into account as TEAEs.
Descriptive statistics will be used to characterize the profiles of drug-related AEs, drug-
related deaths, SAEs, clinical laboratory data, drug-related delays and/or treatment 
discontinuations. Tables will be displayed by study part, sequence and treatment (Test 
or Reference).
9.3.3 Efficacy
Not applicable.
9.3.4 Pharmacokinetics
Plasma exposure to lurbinectedin
Only patients who completed the study with sufficient and interpretable PK parameters 
will be included in the statistical comparison of plasma exposure to lurbinectedin.
Descriptive statistics will be used to summarize pharmacokinetic data.
The primary parameter of interest for the statistical analysis will be plasma dose-
adjusted AUC(0-∞) (if data do not permit so, AUC(0-t) will be used) of lurbinectedin. The 
analysis will compare the log-transformed AUC for lurbinectedin administered in 
combination with itraconazole (Test) to the lurbinectedin alone (Reference). 
A mixed-effects model will be fit to the data with log-transformed AUC as the 
dependent variable, treatment (Test or Reference), period and sequence as fixed effects, 
and patient (sequence) as a random effect. The estimated least square means and 
intrasubject variability from the mixed-effects model will be used to construct 90% CIs 
for the difference in means on the log scale between treatments (Test or Reference). The 
adjusted mean differences and the 90% CIs will be exponentiated to obtain estimates of 
the ratio of adjusted geometric means (Test/Reference) and 90% CIs for the ratios.
A large difference (e.g. two-fold difference shown from CIs and least square means) 
will be considered to show evidence on whether itraconazole co-administration has a 
clinically relevant effect on lurbinectedin exposure.
Secondary PK parameters
Similar models used for the primary endpoint will be fit to the data with dose-

CL_0363 3.0
Page 74 of 93
Protocol PM1183-A-018-20
normalized AUC(0-t) and Cmax and in Cl, Vss and T1/2 of lurbinectedin or metabolite to 
parent exposure PK parameters ratio, as the dependent variable. Results will also be 
assessed graphically.
Plasma protein binding
A similar model used for the primary endpoint will be fit to the data with dose-
normalized AUCu as the dependent variable.
9.3.5 Pharmacogenetics
Descriptive statistics will be used to summarize pharmacogenetic data in a separate 
report.
10. ADMINISTRATIVE SECTION
10.1 ETHICS 
This study will be conducted in accordance with the ethical principles that have their 
origin in the Declaration of Helsinki (Appendix 5) and will be consistent with GCP and 
other applicable regulatory requirements.
The study personnel involved in conducting this study will be qualified by education, 
training and experience to perform their respective task(s).
The study will be conducted in compliance with the protocol. The protocol, any 
amendments, the patient’s diary and the patient ICF will receive IEC approval/favorable 
opinion prior to initiation. The decision of the IEC concerning the conduct of the study 
will be made in writing to the Investigator and a copy of this decision will be provided 
to the Sponsor before commencement of the study.
The Investigator and/or the Sponsor is/are responsible for keeping the IEC informed of 
significant new information about the study drug.
All protocol amendments will be agreed upon by the Sponsor and the Investigator.
Administrative changes of the protocol are minor corrections and/or clarifications that 
have no impact on the way the study is to be conducted.
10.2 MONITORING, AUDITING AND INSPECTING
The study will be monitored by regular site visits and telephone calls to the Investigator 
by the clinical study monitor designated by Pharma Mar, S.A. Source document 
verification may be performed remotely, if required.
During site visits, the study monitor should review original patient records, drug 
accountability records and document retention (study file). Additionally, the monitor 
should observe study procedures and will discuss any problem with the Investigator.
Adequate time for these visits should be allocated by the Investigator. The Investigator 
should also ensure that the monitor is given direct access (as per International 
Conference on Harmonization [ICH] Topic E6 Guideline for Good Clinical Practice, 
GCP) to source documents (i.e., hospital or private charts, original laboratory records, 
appointment books, etc.) of the patient which support data entered in the case report 
forms, as defined in the ICH-GCP.

CL_0363 3.0
Page 75 of 93
Protocol PM1183-A-018-20
Systems and procedures will be implemented to ensure the quality of every aspect of the 
study.
At any time during the course or at the end of the study, the Clinical Quality Assurance 
Department of PharmaMar or external auditors contracted by the Sponsor may conduct 
an onsite or remote audit visit to the centers (ICH-GCP).
Participation in this study implies acceptance of potential onsite or remote inspections 
by national or foreign Competent Authorities.
10.3 PATIENT INFORMED CONSENT
The rights, safety and well-being of the trial patients are the most important 
considerations and should prevail over interests of science and society.
The ICF will include all elements required by ICH, GCP and applicable regulatory 
requirements.
Prior to inclusion into the trial, the Investigator or a person designated by the 
Investigator, must provide the patient with one copy of the Informed Consent Form 
(ICF). This copy must provide written full information about the clinical trial, in a 
language that is non-technical and easily understood. The Investigator should allow the 
necessary time for the patient or his/her legally acceptable representative to inquire 
about the details of the clinical study; then, the ICF must be freely signed and personally 
dated by the patient and by the person who conducted the Informed Consent discussion 
before the beginning of the study. The patient should receive a copy of the signed ICFs 
and any other written information provided to study patients prior to participation in the 
trial.
Participation in the pharmacogenetic sub-study is optional and will need an additional 
ICF signed by the patient. Should the patient decide not to participate in the 
pharmacogenetic sub-study, this will not affect his/her rights to participate in the current 
study.
During a patient's participation in the trial, any updates to the consent forms and any 
updates to the written information will be provided to him/her.
If there is a need to obtain new consent from the patients, the Investigator or a person 
designated by the Investigator should inform the patients of any new information 
relevant to the patients’ willingness to continue participation in the study, before 
obtaining the written consent.
10.4 CONFIDENTIALITY/ PATIENTS IDENTIFICATION
The collection and processing of personal data from patients enrolled in this study will 
be limited to data that are necessary to investigate the efficacy, safety, quality, and 
usefulness of the IMP(s) used in this study. It is the Investigator’s responsibility that 
sufficient information pertaining to the patient’s identity be retained. 
The study monitor, the Sponsor’s auditor, the IEC and the Competent Authorities 
should have direct access to all requested study-related records and agree to keep the 
identity of the study patients confidential.
The data must be collected and processed with adequate precautions to ensure 
confidentiality and compliance with applicable data privacy protection laws and 
regulations.

CL_0363 3.0
Page 76 of 93
Protocol PM1183-A-018-20
Explicit consent for the processing of personal data will be obtained from the 
participating patient before data collection, if applicable, and this consent should also 
address the transfer of the data to other entities and countries.
The Sponsor will comply with General Data Protection Regulation (GDPR) (EU) 
2016/679 effective from 25 May 2018 (repealing Directive 95/46/EC of the European 
Parliament and of the Council of 24 October 1995), and applicable regulations on the 
protection of individuals with regards to the processing of personal data and on the free 
movement of such data. 
10.5 ELECTRONIC CASE REPORT FORMS
Electronic case report forms (eCRFs) will be used to record all data for each patient. It 
is the responsibility of the Investigator to ensure that the eCRFs are properly and fully 
completed in English. ECRFs must be completed for all patients who have given 
informed consent and have been enrolled into the study.
A patient’s source documentation comprises all medical records (including but not 
limited to physician/hospital notes, nurses notes, IMP preparation records including 
reconstitution and dilution, IMP administration records) and any original document, and 
as such they should be maintained at the study site.
The data collected in the eCRF will be entered into the Sponsor’s databases which 
comply with GDPR (EU) 2016/679 effective from 25 May 2018 (repealing Directive 
95/46/EC of the European Parliament and of the Council of 24 October 1995) on the 
protection of individuals with regard to the processing of personal data and on the free 
movement of such data.
10.6 INSURANCE
The Sponsor will provide insurance or indemnity in accordance with the applicable 
regulatory requirements.
10.7 RETENTION OF RECORDS
The Investigator/Institution should maintain study documents according to ICH 
Guideline for Good Clinical Practice and as required by applicable regulatory 
requirements.
Essential documents should be retained as per the aforementioned ICH guideline or for 
a longer period of time, if required by the applicable regulations. 
10.8 USE OF INFORMATION AND PUBLICATION
Before the investigators of this study submit a paper or abstract for publication or 
otherwise publicly disclose information concerning the study drug or products, Pharma 
Mar, S.A. must be provided with at least 60 days to revise and approve the proposed 
publication or disclosure to ensure that confidential and proprietary data are protected.
If Pharma Mar, S.A. determines that patentable patient matter is disclosed in the 
proposed publication or disclosure, the publication or disclosure will be withheld for a 
period of time considered convenient. If the study is part of a multicenter study, the first 
publication of the study shall be made in conjunction with the presentation of a joint, 
multicenter publication of the study results with the investigators and the institutions 
from all appropriate sites that are contributing data, analysis and comments. However, if 

CL_0363 3.0
Page 77 of 93
Protocol PM1183-A-018-20
such a multicenter publication is not submitted within 12 months after conclusion, 
abandonment or termination of the study at all sites, the present study may be published 
individually in accordance with the procedure established above.
The order of the coauthors will reflect the relative contribution of each one to study 
development and analysis. Relevant Sponsor personnel who have fully participated in 
the study must be considered for co-authorship of the publication. In general, the order

APPENDIX 2: CONTRACEPTION AND PREGNANCY TESTING 
This document is based on the Heads of Medicines Agencies’ Recommendations Related 
to Contraception and Pregnancy Testing in Clinical Trials, published by the Clinical 
Trial Facilitation Group (CTFG) on 21 September 2020 and available at 
http://www.hma.eu/ctfg.html (accessed 5 January 2021). 
A woman is considered of childbearing potential (WOCBP) following menarche and 
until becoming post-menopausal unless permanently sterile. Permanent sterilization 
methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A 
postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a post-menopausal state in women not using hormonal 
contraception or hormonal replacement therapy. However, in the absence of 12 months 
of amenorrhea, a single FSH measurement is insufficient. Immediately after detecting a 
case of suspected pregnancy in a patient, the decision on her continued participation in 
the clinical trial will be jointly taken by the patient, the Investigator and the Sponsor, 
with the patient’s best interest in mind. A decision to continue the pregnancy will 
require immediate discontinuation any investigational medicinal product (IMP). 
A man is considered fertile after puberty unless permanently sterile by bilateral 
orchidectomy. Fertile male patients included in this study should refrain from fathering 
a child or donating sperm during the study and for four months following the last IMP 
dose. If they have WOCBP partners the male subject should use condom during 
treatment and for four months following the last IMP dose. 
Highly effective birth control methods are:
1. Combined (estrogen and progestogen containing) hormonal contraception 
associated with inhibition of ovulation 1:
a.
oral 
b. intravaginal 
c.
transdermal 
2. Progestogen-only hormonal contraception associated with inhibition of 
ovulation 1: 
a.
oral 
b. injectable
c.
implantable 2
3. Intrauterine device (IUD) 2
4. Intrauterine hormone-releasing system (IUS) 2
5. Bilateral tubal occlusion 2
6. Vasectomized partner 2,3
7. Sexual abstinence 4
8. A combination of male condom with either cap, diaphragm or sponge with 
spermicide (double barrier methods) are also considered acceptable, but not 
highly effective, birth control methods.
1 Hormonal contraception may be susceptible to interaction with the IMP, which may 
reduce the efficacy of the contraception method (see below).
2 Contraception methods that are considered to have low user dependency. 

CL_0363 3.0
Page 82 of 93
Protocol PM1183-A-018-20
3 Vasectomized partner is a highly effective birth control method provided that partner is the 
sole sexual partner of the WOCBP trial participant and that the vasectomized partner has 
received medical assessment of the surgical success. 
4 Sexual abstinence is considered a highly effective method only if defined as refraining 
from heterosexual intercourse during the entire period of risk associated with the study 
treatments. The reliability of sexual abstinence needs to be evaluated in relation to the 
duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic 
abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhea method (LAM) are not 
acceptable methods of contraception. Female condom and male condom should not be used 
together.
Contraception methods with low user dependency should preferably be used, in 
particular when contraception is introduced as a result of participation in this trial. It 
cannot be excluded that the IMP may reduce exposure to substrates of CYP3A through 
enzyme induction; the efficacy of hormonal contraceptives may be reduced if co-
administered with this drug.

Preamble
1.
The World Medical Association (WMA) has developed the Declaration of 
Helsinki as a statement of ethical principles for medical research involving 
human subjects, including research on identifiable human material and data.
The Declaration is intended to be read as a whole and each of its constituent 
paragraphs should be applied with consideration of all other relevant paragraphs.
2.
Consistent with the mandate of the WMA, the Declaration is addressed primarily 
to physicians. The WMA encourages others who are involved in medical 
research involving human subjects to adopt these principles.
General Principles
3.
The Declaration of Geneva of the WMA binds the physician with the words, 
“The health of my patient will be my first consideration,” and the International 
Code of Medical Ethics declares that, “A physician shall act in the patient's best 
interest when providing medical care.”
4.
It is the duty of the physician to promote and safeguard the health, well-being 
and rights of patients, including those who are involved in medical research. The 
physician's knowledge and conscience are dedicated to the fulfilment of this 
duty.
5.
Medical progress is based on research that ultimately must include studies 
involving human subjects.

CL_0363 3.0
Page 88 of 93
Protocol PM1183-A-018-20
6.
The primary purpose of medical research involving human subjects is to 
understand the causes, development and effects of diseases and improve 
preventive, diagnostic and therapeutic interventions (methods, procedures and 
treatments). Even the best proven interventions must be evaluated continually 
through research for their safety, effectiveness, efficiency, accessibility and 
quality.
7.
Medical research is subject to ethical standards that promote and ensure respect 
for all human subjects and protect their health and rights.
8.
While the primary purpose of medical research is to generate new knowledge, 
this goal can never take precedence over the rights and interests of individual 
research subjects.
9.
It is the duty of physicians who are involved in medical research to protect the 
life, health, dignity, integrity, right to self-determination, privacy, and 
confidentiality of personal information of research subjects. The responsibility 
for the protection of research subjects must always rest with the physician or 
other health care professionals and never with the research subjects, even though 
they have given consent.
10.
Physicians must consider the ethical, legal and regulatory norms and standards 
for research involving human subjects in their own countries as well as 
applicable international norms and standards. No national or international 
ethical, legal or regulatory requirement should reduce or eliminate any of the 
protections for research subjects set forth in this Declaration.
11.
Medical research should be conducted in a manner that minimises possible harm 
to the environment.
12.
Medical research involving human subjects must be conducted only by 
individuals with the appropriate ethics and scientific education, training and 
qualifications. Research on patients or healthy volunteers requires the 
supervision of a competent and appropriately qualified physician or other health 
care professional.
13.
Groups that are underrepresented in medical research should be provided 
appropriate access to participation in research.
14.
Physicians who combine medical research with medical care should involve 
their patients in research only to the extent that this is justified by its potential 
preventive, diagnostic or therapeutic value and if the physician has good reason 
to believe that participation in the research study will not adversely affect the 
health of the patients who serve as research subjects.
15.
Appropriate compensation and treatment for subjects who are harmed as a result 
of participating in research must be ensured.

Protocol PM1183-A-018-20
Risks, Burdens and Benefits
16.
In medical practice and in medical research, most interventions involve risks and 
burdens.
Medical research involving human subjects may only be conducted if the 
importance of the objective outweighs the risks and burdens to the research 
subjects.
17.
All medical research involving human subjects must be preceded by careful 
assessment of predictable risks and burdens to the individuals and groups 
involved in the research in comparison with foreseeable benefits to them and to 
other individuals or groups affected by the condition under investigation.
Measures to minimise the risks must be implemented. The risks must be 
continuously monitored, assessed and documented by the researcher.
18.
Physicians may not be involved in a research study involving human subjects 
unless they are confident that the risks have been adequately assessed and can be 
satisfactorily managed.
When the risks are found to outweigh the potential benefits or when there is 
conclusive proof of definitive outcomes, physicians must assess whether to 
continue, modify or immediately stop the study.
Vulnerable Groups and Individuals
19.
Some groups and individuals are particularly vulnerable and may have an 
increased likelihood of being wronged or of incurring additional harm.
All vulnerable groups and individuals should receive specifically considered 
protection.
20.
Medical research with a vulnerable group is only justified if the research is 
responsive to the health needs or priorities of this group and the research cannot 
be carried out in a non-vulnerable group. In addition, this group should stand to 
benefit from the knowledge, practices or interventions that result from the 
research.
Scientific Requirements and Research Protocols
21.
Medical research involving human subjects must conform to generally accepted 
scientific principles, be based on a thorough knowledge of the scientific 
literature, other relevant sources of information, and adequate laboratory and, as 
appropriate, animal experimentation. The welfare of animals used for research 
must be respected.
22.
The design and performance of each research study involving human subjects 
must be clearly described and justified in a research protocol.

institutional affiliations, potential conflicts of interest, incentives for subjects and 
information regarding provisions for treating and/or compensating subjects who 
are harmed as a consequence of participation in the research study.
In clinical trials, the protocol must also describe appropriate arrangements for 
post-trial provisions.
Research Ethics Committees
23.
The research protocol must be submitted for consideration, comment, guidance 
and approval to the concerned research ethics committee before the study 
begins. This committee must be transparent in its functioning, must be 
independent of the researcher, the sponsor and any other undue influence and 
must be duly qualified. It must take into consideration the laws and regulations 
of the country or countries in which the research is to be performed as well as 
applicable international norms and standards but these must not be allowed to 
reduce or eliminate any of the protections for research subjects set forth in this 
Declaration.
The committee must have the right to monitor ongoing studies. The researcher 
must provide monitoring information to the committee, especially information 
about any serious adverse events. No amendment to the protocol may be made 
without consideration and approval by the committee. After the end of the study, 
the researchers must submit a final report to the committee containing a 
summary of the study’s findings and conclusions.
Privacy and Confidentiality
24.
Every precaution must be taken to protect the privacy of research subjects and 
the confidentiality of their personal information.
Informed Consent
25.
Participation by individuals capable of giving informed consent as subjects in 
medical research must be voluntary. Although it may be appropriate to consult 
family members or community leaders, no individual capable of giving informed 
consent may be enrolled in a research study unless he or she freely agrees.
26.
In medical research involving human subjects capable of giving informed 
consent, each potential subject must be adequately informed of the aims, 
methods, sources of funding, any possible conflicts of interest, institutional 
affiliations of the researcher, the anticipated benefits and potential risks of the 
study and the discomfort it may entail, post-study provisions and any other 
relevant aspects of the study. The potential subject must be informed of the right 
to refuse to participate in the study or to withdraw consent to participate at any 
time without reprisal. Special attention should be given to the specific 

CL_0363 3.0
Page 91 of 93
Protocol PM1183-A-018-20
information needs of individual potential subjects as well as to the methods used 
to deliver the information.
After ensuring that the potential subject has understood the information, the 
physician or another appropriately qualified individual must then seek the 
potential subject’s freely-given informed consent, preferably in writing. If the
consent cannot be expressed in writing, the non-written consent must be 
formally documented and witnessed.
  
All medical research subjects should be given the option of being informed 
about the general outcome and results of the study.
27.
When seeking informed consent for participation in a research study the 
physician must be particularly cautious if the potential subject is in a dependent 
relationship with the physician or may consent under duress. In such situations 
the informed consent must be sought by an appropriately qualified individual 
who is completely independent of this relationship.
28.
For a potential research subject who is incapable of giving informed consent, the 
physician must seek informed consent from the legally authorised representative. 
These individuals must not be included in a research study that has no likelihood 
of benefit for them unless it is intended to promote the health of the group 
represented by the potential subject, the research cannot instead be performed 
with persons capable of providing informed consent, and the research entails 
only minimal risk and minimal burden.
29.
When a potential research subject who is deemed incapable of giving informed 
consent is able to give assent to decisions about participation in research, the 
physician must seek that assent in addition to the consent of the legally 
authorised representative. The potential subject’s dissent should be respected.
30.
Research involving subjects who are physically or mentally incapable of giving 
consent, for example, unconscious patients, may be done only if the physical or 
mental condition that prevents giving informed consent is a necessary 
characteristic of the research group. In such circumstances the physician must 
seek informed consent from the legally authorised representative. If no such 
representative is available and if the research cannot be delayed, the study may 
proceed without informed consent provided that the specific reasons for 
involving subjects with a condition that renders them unable to give informed 
consent have been stated in the research protocol and the study has been 
approved by a research ethics committee. Consent to remain in the research must 
be obtained as soon as possible from the subject or a legally authorised 
representative.
31.
The physician must fully inform the patient which aspects of their care are 
related to the research. The refusal of a patient to participate in a study or the 
patient’s decision to withdraw from the study must never adversely affect the 
patient-physician relationship.
32.
For medical research using identifiable human material or data, such as research 
on material or data contained in biobanks or similar repositories, physicians 

CL_0363 3.0

Protocol PM1183-A-018-20
must seek informed consent for its collection, storage and/or reuse. There may 
be exceptional situations where consent would be impossible or impracticable to 
obtain for such research. In such situations the research may be done only after 
consideration and approval of a research ethics committee.
Use of Placebo
33.
The benefits, risks, burdens and effectiveness of a new intervention must be 
tested against those of the best proven intervention(s), except in the following 
circumstances:
Where no proven intervention exists, the use of placebo, or no intervention, is 
acceptable; or
Where for compelling and scientifically sound methodological reasons the use of 
any intervention less effective than the best proven one, the use of placebo, or no 
intervention is necessary to determine the efficacy or safety of an intervention
and the patients who receive any intervention less effective than the best proven 
one, placebo, or no intervention will not be subject to additional risks of serious 
or irreversible harm as a result of not receiving the best proven intervention.
Extreme care must be taken to avoid abuse of this option.
Post-Trial Provisions
34.
In advance of a clinical trial, sponsors, researchers and host country 
governments should make provisions for post-trial access for all participants 
who still need an intervention identified as beneficial in the trial. This 
information must also be disclosed to participants during the informed consent 
process.
Research Registration and Publication and Dissemination of Results
35.
Every research study involving human subjects must be registered in a publicly 
accessible database before recruitment of the first subject.
36.
Researchers, authors, sponsors, editors and publishers all have ethical 
obligations with regard to the publication and dissemination of the results of 
research. Researchers have a duty to make publicly available the results of their 
research on human subjects and are accountable for the completeness and 
accuracy of their reports. All parties should adhere to accepted guidelines for 
ethical reporting. Negative and inconclusive as well as positive results must be 
published or otherwise made publicly available. Sources of funding, institutional 
affiliations and conflicts of interest must be declared in the publication. Reports 
of research not in accordance with the principles of this Declaration should not 
be accepted for publication.
Unproven Interventions in Clinical Practice
37.
In the treatment of an individual patient, where proven interventions do not exist 
or other known interventions have been ineffective, the physician, after seeking 
expert advice, with informed consent from the patient or a legally authorised 

CL_0363 3.0

Protocol PM1183-A-018-20
representative, may use an unproven intervention if in the physician's judgement 
it offers hope of saving life, re-establishing health or alleviating suffering. This 
intervention should subsequently be made the object of research, designed to 
evaluate its safety and efficacy. In all cases, new information must be recorded 
and, where appropriate, made publicly available.
