Conditions: Pancreatic Cancer
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 18
Healthy volunteers: no

Brief summary:
The primary objective of this study is to:

-Test the activity/response rate per RECIST 1.1 criteria of anetumab ravtansine in patients with advanced pancreatic cancer who stain for mesothelin expression

The secondary objectives of this study are to:

* Time to Progression (TTP) defined as time from study treatment to RECIST 1.1 progression, or death (others going off study will be censored)
* Toxicity in pancreatic cancer patients (at 6.5 mg/kg dose)

Detailed description:
This is a non-randomized, open-label, multicenter, Phase II study to evaluate the efficacy and safety of intravenous anetumab ravtansine (BAY 94-9343), an anti-mesothelin antibody drug conjugate, in pretreated mesothelin-expressing advanced pancreatic cancer.

At the time of the start of study treatment, the patients will have pretreated advanced pancreatic cancer that also overexpresses mesothelin as determined by immunohistochemistry (IHC).

A maximum of 30 patients will be enrolled in a minimax, Simon 2-stage design with a single early stopping rule for lack of efficacy. The target population is those patients with pancreatic cancer who have failed an earlier treatment. All patients will be treated with an anti-mesothelin immuno-conjugate, in this single arm, non-randomized trial and all patients treated with at least one dose of Anetumab will be included. The endpoint is any response using the RECIST 1.1 criteria.

Arms:
arm 1: Patients with advanced metastatic pancreatic cancer who have measurable disease

Interventions: intervention 1: anetumab ravtansine
Intervention descriptions: intervention 1: Patients will receive anetumab ravtansine IV infusion at a dose of 6.5 mg/kg (recommended Phase II dose) on Day 1 of a 21-day cycle

Patients will be treated and undergo imaging scan every 6 weeks.    
RECIST 1.1 criteria to be used for response  
Descriptive statistics of RR (response rate) + 95% CI  
Time to Progression calculated by K-M method  
All patients treated with at least one dose of Anetumab to be included  
A maximum of 30 patients will be enrolled in a minimax, Simon 2-stage 
design with a single early stopping rule for lack of efficacy.  The target 
population is those patients with pancreatic cancer who have failed an 
earlier treatment.  All patients will be treated with an anti-mesothelin 
immuno-conjugate, in this single arm, non-randomized trial.  The 
endpoint is any response using the RECIST 1.1 criteria.  
The minimax, Simon 2-stage design testing 5% null hypothesis versus a 
21% alternative requires a maximum of 30 patients.  If there are no 
patients exhibiting any response among the first 20, which indicates a 
response rate less than 5%, then the trial will terminate early.  If there is at 
least one response among the first 20 (indicating response rate of at least 
5%), then the trial will accrue an additional 10 patients for a maximum of 
30. Four or more responses out of 30 will reject the null hypothesis in 
favor of the 21% response alternative.  These criteria have significance 
level (alpha) 0.1 and power 90%.  The probability of stopping early is 
36% if the response rate is 5% or lower.  The expected sample size is 
26.4.  
Methodology  
Primary efficacy will be assessed based on radiological tumor evaluation 
by contrast-enhanced computed tomography (CT) or contrast-enhanced 
magnetic resonance imaging (MRI) of chest/abdomen/pelvis. During 
treatment as well as active follow-up, tumor imaging will be performed 
with the same modality to the extent possible, every 6 weeks during the 
first 6 months after the start of study treatment, every 9 weeks until the 
end of year 2, and every 12 weeks thereafter until RECIST confirmed 
radiological disease progression or end of study.   
Safety evaluations will be done at full screening, at each clinic visit during 
the treatment period, and at the safety follow-up visit. The National 
Cancer Institute’s Common Terminology Criteria for Adverse Events 
(NCI-CTCAE) version 4.03 will be used to grade severity of adverse 
events (AEs).

Introduction  
3.1  
Background  
Mesothelin is a membrane associated differentiation antigen present on normal mesothelial 
cells and overexpressed in a vast majority of ductal pancreatic adenocarcinomas, 
mesotheliomas, and adenocarcinomas of the ovary.  The biological function of mesothelin 
remains unknown and mesothelin-deficient mice have no obvious phenotype of defect. 
Mesothelin is an internalizing antigen and shows a restricted expression profile in normal 
tissue making it an excellent target for antibody directed cytotoxic drug delivery.  
BAY 94-9343, anetumab ravtansine, is an antibody-drug conjugate consisting of a fully 
human IgG1 antibody (MF-T, BAY 86-1903) directed at the mesothelin antigen and 
conjugated to a synthetic cytotoxic anticancer agent, maytansine derivative (DM4, BAY 
1006640) as toxophore through a reducible disulfide linker (SPDB).  Preclinical efforts have 
shown specific effects on mesothelin positive cell lines and in xenograft models including 
activity in pancreatic BxPC3 xenograft model.  Toxicology studies showed a number of 
important signals but specifically skin toxicity.  
Human phase 1 and PK studies were performed showing terminal phase half-life values of the 
ADC and Total Antibody were approximately 5.5 to 6 days. Plasma DM4 and DM4-Me 
concentrations declined with a half-life of approximately 3 days and 5.5 days at the MTD. DM4-
Me pharmacokinetics exhibited moderate to high variability and exposure increased in a 
substantially more than dose proportional manner in the dose range studied.  
The safety results from the dose escalation part of the first-in-human study 15051 in 45 
patients with advanced cancer (BAY 94-9343 dose range, 0.15-7.5 mg/kg q3w) were as 
follows: 1) The non-tolerable dose of BAY 94-9343 was 7.5 mg/kg q3w; the non-tolerable 
toxicities at 7.5 mg/kg q3w were corneal toxicity (blurry vision and keratitis due to corneal 
epitheliopathy), peripheral neuropathy and increase in serum amylase and lipase; 2) The 
maximum tolerated dose was 6.5 mg/kg q3w; the only dose-limiting toxicity observed at this 
dose level was the asymptomatic Grade 3 increase in serum AST/ALT; 3) The most common 
treatment-emergent adverse events at least possibly related to BAY 94-9343 were fatigue, 
nausea, vomiting, anorexia, peripheral neuropathy, myalgia, weakness and diarrhea. The most 
common treatment-emergent lab abnormalities were lymphopenia, hypoalbuminemia, 
hyponatremia, hyperglycemia and hypokalemia; 4) at doses below the non-tolerated dose, the 
TEAEs were mostly mild and not clinically significant except for cardiac chest pain, 
hypertension, grade 3 increase in ALT and AST, and decrease in platelets and sodium.  
The safety results from the MTD Expansion 6.5 mg/kg q3w cohort, which evaluated the MTD 
for BAY 94-9343 determined in the dose escalation cohorts were as follows: 1) BAY 94-9343 
at 6.5 mg/kg given IV once every 3 weeks was considered tolerable in the two cohorts of 
subjects with ovarian cancer (n=20) and pleural or peritoneal mesothelioma (n=12); 2) 
Overall, 16 of 32 (50%) subjects treated at 6.5 mg/kg q3w have required dose reduction to 5.5 
mg/kg q3w and 4 (25%) of these subjects required another dose reduction to 4.5 mg/kg; 3) the 
safety finding of particular relevance was the high incidence of corneal toxicity (blurred 
vision and keratitis with vision impairment due to corneal epithelial microcysts or deposits in 
12 of 32 subjects) causally attributed to BAY 94-9343; 4) although being fully reversible in 
the vast majority of cases, the corneal toxicity invariably necessitated lengthy treatment 
interruption and dose reduction; 5) otherwise the safety profile of BAY 94-9343 in the MTD

Expansion 6.5 mg/kg q3w cohort was very similar to that observed in dose escalation cohorts 
up to and including the Cohort 9 (6.5 mg/kg q3w), with mostly mild TEAEs and remarkably 
low incidence of drug-related SAEs.  One patient in a Japanese cohort with pancreatic cancer 
developed drug-induced liver injury.    
We will therefore pursue the 6.5 mg/kg dose, as having an acceptable incidence of corneal 
toxicity and keratitis and as the phase II dose in use for current studies.  
3.2  
Rationale of the study  
The need for new treatments for pancreatic cancer is great.  At the MTD of 6.5 mg/kg Q3W, 
anetumab ravtansine has demonstrated a tolerable safety profile and efficacy in pancreatic 
cancer.  If this study shows promise, with at least 21% of treated patients showing RECIST 
response, or prolonged delay in progression compared with historical controls, this would 
suggest the potential to impart large clinical benefit and warrant larger controlled trials.  
4.  
Study objectives  
The primary objective of this study is to:  
• 
Test the activity/response rate per RECIST 1.1 criteria of anetumab ravtansine in patients 
with advanced pancreatic cancer who stain for mesothelin expression  
  
The secondary objectives of this study are to:  
• 
Time to Progression (TTP) defined as time from study treatment to RECIST 1.1 
progression, or death (others going off study will be censored)   
• 
Toxicity in pancreatic cancer patients (at 6.5 mg/kg dose)  
5.  
Study design  
5.1  
Design overview  
This is a non-randomized, open-label, multicenter, Phase II study to evaluate the efficacy and 
safety of intravenous anetumab ravtansine (BAY 94-9343), an anti-mesothelin antibody drug 
conjugate, in pretreated mesothelin-expressing advanced pancreatic cancer.  
At the time of the start of study treatment, the patients will have pretreated advanced 
pancreatic cancer that also overexpresses mesothelin as determined by immunohistochemistry 
(IHC).  Mesothelin testing will be performed centrally.  
A maximum of 30 patients will be enrolled in a minimax, Simon 2-stage design with a single 
early stopping rule for lack of efficacy.  The target population is those patients with pancreatic 
cancer who have failed an earlier treatment.  All patients will be treated with an anti-
mesothelin immuno-conjugate, in this single arm, non-randomized trial and all patients treated 
with at least one dose of Anetumab will be included.  The endpoint is any response using the 
RECIST 1.1 criteria.  
The minimax, Simon 2-stage design testing 5% null hypothesis versus a 21% alternative 
requires a maximum of 30 patients.  If there are no patients exhibiting any response among 
the first 20, which indicates a response rate less than 5%, then the trial will terminate early. If 
there is at least one response among the first 20 (indicating response rate of at least 5%) then 
the trial will accrue an additional 10 patients for a maximum of 30. Four or more responses 
out of 30 will reject the null hypothesis in favor of the 21% response alternative.  These

criteria have significance level (alpha) 0.1 and power 90%.  The probability of stopping early 
is 36% if the response rate is 5% or lower.  The expected sample size is 26.4.  
The start of the treatment period is defined by first administration of study drug (anetumab 
ravtansine). Patients will receive anetumab ravtansine IV infusion at a dose of 6.5 mg/kg 
(recommended Phase II dose [RPIID]) on Day 1 of a 21-day cycle. Treatment will be 
continued until death or occurrence of PD as defined by Response Evaluation Criteria in Solid 
Tumors (RECIST) v1.1 and assessed by blinded radiology review, or clinical progression, or 
until another criterion for withdrawal from the study is met.   
Patients who discontinue study treatment for any reason other than confirmed radiological PD 
will be followed for progression during active follow-up (which includes the safety follow-up 
period) until confirmed PD for this patient is observed.  
All patients who end study treatment for any reason will be followed for OS and the start of 
any new anti-cancer treatment every 3 months during the long-term follow-up period until 
data maturation for the OS final analysis is reached, or until death, consent withdrawal or end 
of study, whichever occurs first.  
Primary efficacy will be assessed based on radiological tumor evaluation by contrast-
enhanced computed tomography (CT) or contrast-enhanced magnetic resonance imaging 
(MRI) of chest/abdomen/pelvis. During treatment as well as active follow-up, tumor imaging 
will be performed with the same modality to the extent possible, every 6 weeks during the 
first 6 months after the start of study treatment, every 9 weeks until the end of year 2, and 
every 12 weeks thereafter until RECIST confirmed radiological disease progression or end of 
study.   
Safety evaluations will be done at full screening, at each clinic visit during the treatment 
period, and at the safety follow-up visit. The National Cancer Institute’s Common 
Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03 will be used to grade 
severity of adverse events (AEs).  
Patients will be contacted to assess survival status every 3 months during long-term follow-
up.  In addition, extra survival sweep contacts will be conducted at the time of PFS final 
analysis and prior to OS final analysis to ensure that long-term follow-up data is current.

22. 
Any prohibited prior or concomitant therapy (see Table 2-8 in Section 8.1).  
6.3  
Withdrawal of patients from study  
6.3.1 Screening failure  
6.3.1.1  
Prescreening failure  
A patient whose tumor tissue is tested by IHC for mesothelin overexpression and whose result 
is not moderate (2+) and stronger (3+) mesothelin overexpression in at least 30% of the tumor 
cells, or who fails to meet any of the other eligibility criteria for prescreening, is regarded as a 
“prescreening failure”. These patients should not undergo any further screening procedures.  
6.3.1.2  
Full screening failure  
A patient who passes the prescreening, including the mesothelin overexpression testing, 
but for any other reason (e.g., failure to satisfy the remaining selection criteria) terminates 
the study before enrollment is regarded as a “full screening failure”. See Section 11.1 for 
data to be collected for screening failures.  
Re-starting the defined set of screening procedures to enable the “screening failure” patient’s 
participation at a later time point is not allowed – with the following exceptions:  
• 
The patient had successfully passed the screening procedures, but could not start 
subsequent treatment on schedule.  
• 
Initial screening occurred too early to complete the required washout period after prior 
therapy.  
• 
The in- / exclusion criteria preventing the patient’s initial attempt to participate have been 
changed (via protocol amendment).  
• 
Equivocal screening results require further testing for clarification even if, for logistical 
reasons, the further testing cannot be performed within the allocated time window (e.g. 
equivocal laboratory creatinine clearance requiring formal creatinine clearance 
measurement).  
• 
Resolution of toxicity, now meeting all criteria  
In any case, the investigator has to ensure that the repeated screening procedures do not 
expose the patient to an unjustifiable health risk. Also, for re-screening, the patient has to 
resign the main consent document (for the full study), even if it was not changed after the 
patient’s previous screening.

6.3.2  Withdrawal criteria  
All patients who enter the study should complete all phases of the study unless they are screen 
failures or meet the criteria for withdrawal. Phases of the study include:  
1. Prescreening  
2. Full screening  
3. Registration  
4. Treatment  
5. Safety follow-up  
6. Active follow-up  
7. Long-term follow-up  
Study treatment discontinuation (i.e., discontinuation during the treatment period) does not 
constitute withdrawal from the study.  
Every effort should be made to retain patients who discontinue the treatment period for any 
reason. These patients are to be encouraged to remain on the study for follow-up of primary, 
secondary and other objectives (i.e., continue in the safety follow-up, active follow-up and/or 
long-term follow-up periods).  
Patients are expected to participate in the follow-up unless they explicitly object. Withdrawal 
of consent to treatment should be documented in the patient’s medical record. If the patient 
does not wish to be followed up further, this additional consent withdrawal for follow up 
would have to be documented, too.  
Withdrawal from study treatment, active follow-up and long-term follow-up  
Patients withdrawn from the study treatment phase of the study should be followed for 
primary, secondary and other objectives (i.e. continue in the safety follow-up, active followup 
and/or long-term follow-up periods) (see Figure 2-1 for withdrawal criteria).

Withdrawal criteria  
PATIENTS MUST BE WITHDRAWN FROM THE STUDY TREATMENT IF ANY OF THE FOLLOWING 
OCCURS:  
• 
At their own request or at the request of their legally acceptable representative. At any time during the study and 
without giving reasons, a patient may decline to participate further. The patient will not suffer any disadvantage as 
a result.  
• 
If, in the investigator's opinion, continuation of the study treatment would be harmful to the patient's well-being.  
• 
At the specific request of the sponsor and in liaison with the investigator (e.g. obvious non-compliance, safety 
concerns).  
• 
Confirmed radiological PD as per RECIST criteria.  
• 
Clinical progression as assessed by investigator. Occurrence of unacceptable toxicity to anetumab ravtansine (see 
also Section 7.3.2).  
• 
CTCAE Grade 4 hypersensitivity and acute infusion reaction.  
• 
An adverse reaction deemed sufficiently serious to warrant discontinuation of treatment by the investigator or his 
designated associate(s).   
• 
Development of a secondary malignancy.  
• 
Patient starts treatment with any other anti-cancer therapy or any other prohibited medication as per Section 8.1.  
• 
Positive serum β-HCG test consistent with pregnancy. Pregnancy should be reported along the same timelines as 
an SAE.   
• 
Use of illicit drugs or other substances that may, in the opinion of the investigator or his designated associate(s), 
have a reasonable chance of contributing to toxicity or otherwise confound the results.   
• 
Development of any intercurrent illness or situation which may, in the judgment of the investigator, affect 
assessments of clinical status and study endpoints to a relevant degree.   
• 
Lost to follow-up.  
• 
Death.  
Patients must be withdrawn from treatment with anetumab ravtansine if any of the following occurs:  
• 
CTCAE Grade 4 non-hematological AE and Bayer Grade 4 corneal toxicity (see Table 2-6) (except at the 
investigator’s discretion in case of certain Grade 4 abnormality of laboratory assessments, such as abnormal 
laboratory assessments without corresponding clinical symptoms, or abnormal laboratory assessments that can be 
easily clinically managed).  
• 
If any type of TEAE requiring dose modification does not resolve to Grade ≤ 1 (or Hb ≥ 8 g/dL in case of anemia) 
within 6 weeks after the last dose of anetumab ravtansine.  
• 
Delay in anetumab ravtansine administration of 3 weeks (max. 6 weeks between 2 infusions of study drug).  
• 
TEAE requiring dose reduction when already at the 4.5 mg/kg Q3W dose level (minimum dose).  
•

Stability of the reconstituted solution  
Exposure to bright light should be avoided; standard room illumination does not necessitate 
any precautions.  
The reconstituted solution is physically and chemically stable for 24 h at room 
temperature and between 2°C and 8°C. However, unless administered immediately, for 
microbiologic consideration, the reconstituted solution should be stored between 2°C and 
8°C and used within 6 h according to USP 797 “Pharmaceutical Compounding – Sterile 
preparations”. If not reconstituted under aseptic conditions, the solution should be used 
immediately or stored at 2°C to 8°C and used within 1 h, according to USP 797.  
If frozen or stored above 25°C (77°F), the solution should be discarded.  
Stability of the diluted solution  
Exposure to bright light should be avoided; standard room illumination does not necessitate 
any precautions.  
Stability investigations have shown that if diluted under aseptic conditions, concentrations 
between 0.1 and 3.0 mg/mL are stable for the period of use (24 h) at room temperature and 
between 2°C and 8°C. However, unless administered immediately, for microbiologic 
consideration, diluted solution should be stored between 2°C and 8°C and used within 6 h 
according to USP 797 “Pharmaceutical Compounding – Sterile preparations”.  
If not diluted under aseptic conditions, the solution should be used immediately or stored at 
2°C to 8°C and used within 1 h, according to USP 797.  
If frozen or stored above 25°C, the solution should be discarded.  
Refer to IB for anetumab ravtansine for details regarding drug properties and formulation.  
7.3  
Dosage and administration  
7.3.1  Administration of anetumab ravtansine  
After reconstitution and dilution (as described in Section 7.2.1), anetumab ravtansine will be 
administered as a 1-hour IV infusion every 3 weeks on Day 1 of each 21-day cycle until 
confirmed radiological PD by RECIST 1.1, clinical progression as assessed by investigator, or 
any other criteria for withdrawal of treatment.  
The individual dose will be 6.5 mg/kg per infusion from Cycle 1 onwards. In obese patients, 
anetumab ravtansine dose should be calculated considering a maximum weight of 100 kg.  
Strict IV administration has to be ensured to avoid local intolerance reactions. After 
completion of the 1-hour anetumab ravtansine infusion, the infusion line will be rinsed with 
≥ 100 mL of 0.9% saline solution to be administered as a short infusion.  
See Section 9.1 for details on scheduled administrations. 
 
7.3.2  Dose modification  
The NCI-CTCAE v4.03 will be used to assess toxicities; in addition, a Bayer grading system 
(see Table 2-6 and Table 2-7) will be used to assess corneal toxicity.

TEAE requiring dose modification (temporary treatment interruption, dose reduction, or 
permanent discontinuation of treatment) will be defined as any of the events described below 
that is possibly, probably, or definitely related to anetumab ravtansine and occurs anytime 
during the study (not only in Cycle 1).  
The dose reduction levels of anetumab ravtansine will follow pre-defined dose levels shown 
in Table 2-2.  
 
Table 2-2  
Dose levels of anetumab ravtansine  
Dose level 1 (starting dose):  
6.5 mg/kg Q3W  
Dose level -1:  
5.5 mg/kg Q3W  
Dose level -2:  
4.5 mg/kg Q3W  
Q3W = Every 3 weeks  
  
7.3.2.1  
Hematological toxicities  
Dose modifications for hematological toxicity  
• 
If treatment modification is required due to a hematological TEAE, and the 
continuation of treatment is appropriate, the anetumab ravtansine dose will be adjusted 
as described in Table 2-3 and Table 2-4 below.  
• 
G-CSF and other hematopoietic growth factors may be used during the study in the 
management of acute toxicity such as febrile neutropenia when clinically indicated per 
ASCO Recommendations for Therapeutic Use of CSF (26) or at the discretion of the 
investigator; however, they may not be substituted for a required dose reduction.  
• 
Blood transfusions and therapy with IV or subcutaneous erythropoietin-stimulating 
agents (epoetin alpha, darbepoetin alpha) are allowed per institution guidelines but may 
not be used as substitute for a required dose reduction (see also Table 2-8).  
• 
Platelet transfusion may be used during the study in the management of acute toxicity 
such as hemorrhage or bleeding events, however they may not be used as substitute for 
a required dose reduction.

ALT = Alanine aminotransferase; AST = Aspartate aminotransferase; CTCAE = Common 
Terminology Criteria for Adverse Events; Q3W = Every 3 weeks; TEAE = Treatment-emergent 
adverse event  
a 
AST and/or ALT increase of CTCAE Grade 2 with concomitant increase in total bilirubin of 
CTCAE Grade 2 will be treated as a CTCAE Grade 3 event.  
b 
Treatment will be discontinued if the TEAE fails to resolve to Grade ≤ 1 within 6 weeks after the 
last dose of anetumab ravtansine.  
c 
Dose reduction by 1 dose level translates to a change from 6.5 mg/kg Q3W to 5.5 mg/kg Q3W, or 
from 5.5 mg/kg Q3W to 4.5 mg/kg Q3W. Not more than 2 dose reductions from the starting dose 
level are permitted.  
  
The anetumab ravtansine dose reduction due to non-hematological TEAE will be done as 
described below:  
• 
If the patient experienced a TEAE requiring dose reduction at the 6.5 mg/kg Q3W 
dose level, the subsequent anetumab ravtansine dose should be reduced to 5.5 mg/kg 
Q3W.  
• 
If the patient experienced a TEAE requiring dose reduction at the 5.5 mg/kg Q3W 
dose level, the subsequent anetumab ravtansine dose should be reduced to 4.5 mg/kg 
Q3W.  
After dose reduction, there could be no intra-patient dose escalation irrespective of the type of 
TEAE that has led to dose reduction in this patient.  
 
7.3.2.3  
Miscellaneous toxicities  
IV infusion reaction and other hypersensitivity events  
If a patient experiences a CTCAE Grade 2 or Grade 3 anetumab ravtansine infusion reaction 
or other CTCAE Grade 2 or Grade 3 hypersensitivity event deemed at least possibly related to 
anetumab ravtansine, the infusion of anetumab ravtansine will be interrupted.  
If treatment interruption is caused by a CTCAE Grade 2 or Grade 3 anetumab ravtansine 
infusion reaction or other CTCAE Grade 2 or Grade 3 hypersensitivity event deemed at least 
possibly related to anetumab ravtansine, treatment may be re-started at the time determined at 
the investigator’s discretion. Re-treatment should be at the infusion rate reduced by 50%, along 
with anti-allergic prophylaxis (e.g. anti-histamines, acetaminophen, and/or corticosteroids) 
chosen at the investigator’s discretion or according to the institutional guidelines.  
Miscellaneous toxicities requiring dose modification  
For any toxicity ≤ Grade 2 assessed as related to anetumab ravtansine by the investigator, 
dose modification should be considered. Such toxicities might be ≤ Grade 2 toxicities which 
interfere with the activities of daily life, such as long lasting fatigue, or anorexia, or corneal 
toxicity with vision impairment etc. A dose change might be necessary in order to ensure the 
patient’s compliance. These toxicities may be declared “TEAE requiring treatment 
modification” after consultation between the investigator and the sponsor.

Dose modifications for corneal toxicity  
For the TEAE of corneal morphology changes and the best corrected visual acuity (BCVA) 
changes (blurred vision), the Bayer severity grading system (see Table 2-6 and Table 2-7) will 
be used to assess the severity of TEAEs requiring modification of anetumab ravtansine 
treatment.  
TEAE of corneal morphology changes deemed to be at least possibly related to anetumab 
ravtansine would require modification of anetumab ravtansine treatment (dose reduction or 
permanent discontinuation of treatment) according to the following principles (see Table 2-6).

Recommended measures in case of eye dryness and ocular hypertension  
Changes in tear production as evaluated by the Schirmer test and in intraocular pressure (IOP) 
are not expected to occur as a direct consequence of anetumab ravtansine therapy. However, 
IOP may increase in some patients as a consequence of the therapy with topical steroid 
eyedrops. Since these drugs may be required to manage the corneal epitheliopathy syndrome, 
IOP will be monitored during this study for patients receiving topical steroid eyedrops.  
Changes in IOP should be managed by the investigator following exam by an 
ophthalmologist. The remedial therapy should be chosen at investigator’s discretion or 
according to the institutional standards; therapeutic measures can include modification of the 
type or posology of topical steroid eye drop, initiation of topical IOP lowering drugs and any 
other therapeutic options according to the local SoC. Ophthalmological monitoring should be 
maintained until the IOP has returned to normal values.  
Reductions in tear production evaluated by the Schirmer test, while not being a part of the 
corneal epitheliopathy syndrome, are a risk factor for developing ocular surface disease 
including corneal epithelial defects. Therefore, the tear production will be evaluated in this 
study to determine if changes in this parameter may be helpful to identify patients at higher 
risk of developing the corneal epitheliopathy syndrome. Abnormal values in the Schirmer test 
should be evaluated and managed by the investigator following exam by an ophthalmologist 
to provide adequate protection to the corneal epithelium. The remedial therapy for the 
treatment-emergent changes in the Schirmer’s test (dry eye) should be chosen at 
investigator’s discretion or according to the institutional standards. These measures may 
include topical lubricants such as eye drops and ointments, punctual occlusion, use of 
therapeutic contact lenses and any other treatment approaches according to the local SoC.

7.3.2.4  
Continuation of treatment with anetumab ravtansine  
Treatment with anetumab ravtansine could be re-started at the appropriate dose if the TEAE 
requiring dose modification has resolved to Grade < 2 within 6 weeks after the last dose of 
anetumab ravtansine.  
 
7.3.2.5  
Permanent discontinuation of anetumab ravtansine due to TEAEs  
See Section 6.3.1.2 for withdrawal criteria.  
7.4  
Drug logistics and accountability  
All study drugs will be stored at the investigational site in accordance with GCP and GMP 
requirements and the instructions given by the clinical supplies department of the sponsor, 
and will be inaccessible to unauthorized personnel. Special storage conditions and a complete 
record of batch numbers and expiry dates can be found in the sponsor’s study file; the site-
relevant elements of this information will be available in the investigator site file. The 
personnel will use the study drug only within the framework of this clinical study and in 
accordance with this protocol. Receipt, distribution, return and destruction (if any) of the 
study drug must be properly documented according to the sponsor’s agreed and specified 
procedures.  
The Yale Cancer Center (YCC) will be the coordinating center for the distribution of drugs or 
supplies to the participating institution(s). The Investigational Drug Service (IDS) at Yale-
New Haven Hospital will be employed to serve as the central pharmacy.  Distribution of 
drugs and supplies will be conducted in adherence with the established policies of Yale-New 
Haven Hospital and Medical Center  
The study drug will be provided by Bayer and shipped to the IDS at Yale-New Haven  
Hospital which will then distribute to the collaborating sites. Drug vials will be provided by 
Bayer with a generic non-study specific label on the cartons containing the vials. Any study 
specific labeling to the vials to meet local requirements will need to be done by the IDS.  The 
vials will be distributed to collaborating sites as required by IDS.  
The number of vials used will be recorded on the appropriate treatment dispensing form. 
Reasons for dose delay and reduction will be recorded in the source documents and on the 
CRF.  
Treatment accountability on patient level must be verified at every cycle, starting on C1D1. 
The monitor will review overall drug accountability and destruction per the site 
documentation only.  
Written instructions on medication destruction will be made available to affected parties as 
applicable.

7.5  
Treatment compliance  
The administration of anetumab ravtansine will be performed in the clinic on Day 1 of each 
21-day cycle for anetumab ravtansine. Each administration must be recorded on the CRF and 
Drug Dispensing / Accountability Form.  
Reasons for dose delay, reduction, or omission will also be recorded in the source documents 
and on the CRF.  
An adequate record of receipt, distribution, and return of all study drugs must be kept in the 
form of a Drug Accountability Form.  
The preparation and administration of anetumab ravtansine will be performed by members of 
the investigator team during hospitalization and site visits. These persons will ascertain and 
document that the patient receives all treatments as planned.  
Patient compliance with the treatment and protocol includes willingness to comply with all 
aspects of the protocol, and to have blood collected for all safety evaluations. At the 
discretion of the principal investigator or sponsor, a patient may be discontinued from the 
study treatment for non-compliance with visits or study drug.

Non-study therapy  
8.1  
Prior and concomitant therapy  
Any medication which is considered necessary for the patient’s welfare, and which is not 
expected to interfere with the evaluation of the study treatment, may be given at the discretion 
of the investigator. In general, patients should be closely monitored for side effects of all 
concomitant medications regardless of elimination path, especially those with narrow 
therapeutic indices, such as warfarin, phenytoin, quinidine, carbamazepine, phenobarbital, 
cyclosporine, and digoxin. From signing of consent for full study to safety follow-up visit, all 
concomitant medications (including start/stop dates, dose, frequency, route of administration 
and indication) must be recorded in the patient’s source documentation, as well as on the 
appropriate pages of the CRF. At prescreening and during active follow-up period, only 
concomitant medications that are administered to treat AEs related to study-specific 
procedures are mandatory to be reported. Administration of contrast media for protocol-
specified radiological procedures (CT scan or MRI) does not need to be reported on the 
concomitant medication CRF page, unless there is an AE related to the contrast medium 
injection (e.g. allergic reaction).  
Prohibited prior and concomitant therapies and permitted concomitant therapies are listed in 
Table 2-8 and Table 2-9, respectively.

Prophylactic standard anti-emetics  
May be administered according to standard practice: 
dexamethasone plus 5-HT3 blockers, such as granisetron, 
ondansetron, or an equivalent agent, are allowed on “as 
needed” basis.  
Treatment with non-conventional therapies 
(for example herbs, except St John’s Wort, 
or endpoints, in the opinion of the 
investigator. acupuncture), and 
vitamin/mineral supplements 
Acceptable provided that they do not interfere 
with the study  
Bisphosphonates or denosumab, with supplement 
of calcium and vitamin D  
Palliative (e.g. analgesics) and supportive care 
(e.g. nutritional therapy) for other disease-related 
symptoms and for toxicity associated with 
treatment  
 
Strong P-gp inhibitors (e.g. amiodarone, 
azithromycin, captopril, carvedilol, 
clarithromycin, conivaptan, cyclosporine, 
diltiazem, dronedarone, erythromycin, 
felodipine, itraconazole, ketoconazole, 
lopinavir and ritonavir, quercetin, quinidine, 
ranolazine, ticagrelor, verapamil)  
DM4-Me (metabolite of DM4) is a P-gp substrate.   
Caution should be exercised with concomitant administration of 
strong P-gp inhibitors. If anetumab ravtansine must be co-
administered with a strong P-gp inhibitor, then the patient 
should be carefully monitored or the strong P-gp inhibitor 
replaced at investigator’s discretion.  
 
Narrow therapeutic index medications   
Patients taking narrow therapeutic index medications should be  
monitored proactively, if these medications cannot be avoided.  
 
Beta blockers or digoxin   
Permitted for patients with cardiac arrhythmias requiring therapy  
5-HT3 = 5-hydroxytryptamine (serotonin); DM4 = Derivatives of maytansine 4; DM4-Me = Methyl-DM4; ILD 
= Interstitial lung disease; PD = Progressive disease; P-gp = Permeability glycoprotein  
  
All prior anti-cancer therapies, and all concomitant therapies including ophthalmological 
therapies as of full screening will be recorded on the CRF. At prescreening and during active 
follow-up period, only concomitant medications that are administered to treat AEs related to 
study-specific procedures are mandatory to be reported.  
8.2  
Post-study therapy  
At the end of study treatment, further therapy is at the discretion of the investigator.  
No results are available from human interaction studies between anetumab ravtansine and 
other chemotherapies. No data are available to evaluate the potential interaction between 
anetumab ravtansine and radiation treatment. Therefore, when administering these agents 
after study treatment is withdrawn, it should be taken into consideration that anetumab 
ravtansine, DM4 or DM4-Me levels may be detectable for several weeks and could interact 
with chemotherapy and radiotherapy including palliative radiotherapy as outlined in Table 2-9 
following discontinuation of anetumab ravtansine.

The primary efficacy variable is progression-free survival (PFS) based on assessment of the 
investigator’s review. For definition and analysis of the primary variable and for description 
of secondary and other variables, please refer to Section 10.2.  
9.4.1  
Radiological tumor assessments  
The first radiological (contrast-enhanced CT/MRI of chest/abdomen/pelvis) tumor evaluation 
will be conducted during full screening within 28 days before the start of study treatment (see 
flow chart in Section 9.1). Pre-study CT/MRI may be acceptable as a baseline scan if done 
within 28 days, if evaluable for RECIST measurement in TIMC. Baseline CT/MRI should be 
obtained prior to start of treatment. A sole positron emission tomography (PET) scan without 
a diagnostic CT/MRI is not acceptable for radiological evaluation of target lesions; findings 
must be confirmed by CT or MRI. Although PET scan findings may be used as supportive 
evidence of tumor assessment, the CT or MRI results will be the definitive and documented 
data for the study. All subsequent scans should be done with the identical method and 
technique (e.g. slice thickness, field of view) to those obtained at baseline. These screening 
images will be reviewed to confirm there are measurable lesions in TIMC.  If focal 
neurological symptoms are present at screening, a CT scan or MRI of the brain is required to 
rule out brain metastasis by the investigator. All additional suspected sites of disease should 
be imaged (e.g. cervical lymph nodes, bone etc.).  
During treatment as well as active follow-up, tumor imaging and local assessments will be 
performed for the following time points: every 6 weeks for the first 6 months after the start of 
study treatment, every 9 weeks until the end of year 2, and every 12 weeks thereafter until 
confirmed radiological disease progression or end of study. Visit window of +/- 7 days is 
allowed. MRI shall be performed instead of CT when local regulations do not permit the use 
of CT as requested per protocol schedule.  
All images need to be sent to the Yale Diagnostic Radiology (YDR) Precision Metrics service 
immediately after they are obtained.

Investigators will determine treatment response locally at each investigational site according 
to RECIST 1.1 criteria. Preferably all scans should be interpreted by the same 
radiologist/investigator during the study.  
In the event of locally suspected progression, the imaging will be reviewed by radiology and 
investigator.  Radiological confirmation by independent blinded evaluation is required before 
a final decision to stop the treatment is made. The site should also wait for the review results 
before administering the next dose of treatment. In case of uncertain radiological disease 
progression, the patient may stay on treatment at the investigator’s discretion until 
progression is definitely confirmed by review on the subsequent tumor assessment.  
When the review assessment confirms progression, study treatment should be stopped 
permanently and patient will enter safety follow-up (safety follow-up visit to be scheduled 30 
(+/-7) days after the last administration of study treatment) and long-term follow-up period.  
In the event the review assessment does not find progression, the severity and clinical 
significance of local PD finding should be assessed. If patient has not significantly clinically 
deteriorated and has no toxicity requiring withdrawal, the patient should continue on 
treatment and further imaging should be conducted as per protocol required timelines. If 
patient has clinically deteriorated or has toxicity such that keeping patient on treatment would 
be against patient’s interest, the study treatment should be stopped permanently. The patient 
will enter the safety follow-up (safety follow-up visit to be scheduled 30 (+/-7) days after the 
last administration of study treatment) and active follow-up period.  
The PD events for the primary endpoint of this study, and the time point and best response 
values for the secondary response endpoints, will be determined by independent blinded 
reviewers according to RECIST criteria.  
The final evaluation of treatment response will be done by Yale Diagnostic Radiology  
Precision Metrics review retrospectively. The reviewer will determine the response per 
RECIST 1.1 criteria of each patient as of each time point. Responses of CR and PR will be 
confirmed by repeated observation per mRECIST criteria. Confirmed responses of CR and 
PR will be dated per mRECIST criteria.  
In case a patient discontinues study for reasons other than confirmed disease progression and 
does not want to enter or stay in the active-follow-up, information on locally confirmed date 
of progression should be collected during long-term follow-up. Progression results not 
documented by collected imaging will be classified as clinical progression and used in 
sensitivity analysis.  
9.4.2  
Survival  
Patients will be contacted for survival every 3 months (±14 days) during long-term follow-up 
until data maturation for the OS final analysis is reached, death, withdrawal of consent, lost to 
follow-up or the end of study, whichever occurs first (see flow chart in Section 9.1). In 
addition, extra survival sweep contacts will be conducted at the time of PFS final analysis and 
prior to OS final analysis to ensure that long-term follow-up data is current.

9.5.1  
Adverse events  
9.5.1.1. Definition of adverse event (AE)  
In a clinical study, an AE is any untoward medical occurrence (i.e. any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a patient or 
clinical investigation subject after providing written informed consent for participation in the 
study. Therefore, an AE may or may not be temporally or causally associated with the use of 
a medicinal (investigational) product.  
A surgical procedure that was planned prior to the start of the study by any physician treating 
the patient should not be recorded as an AE (however, the condition for which the surgery is 
required may be an AE).  
New lesions or disease progression per se should not be regarded as AEs. Instead, the 
associated signs and symptoms should be recorded as AEs.  
In the following differentiation between medical history and AEs, the term “condition” may 
include abnormal e.g. physical examination findings, symptoms, diseases, laboratory, ECG.  
• Conditions that started before signing of informed consent for full study and for 
which no symptoms or treatment are present until signing of informed consent for 
full study are recorded as medical history (e.g. seasonal allergy without acute 
complaints).  
• Conditions that started before signing of informed consent for full study and for 
which symptoms or treatment are present after signing of informed consent for full 
study, at unchanged intensity, are recorded as medical history (e.g. allergic 
pollinosis).  
• Conditions that started or deteriorated after signing of informed consent for full study 
will be documented as AEs. This includes intercurrent illnesses.  
9.5.1.2 Definition of serious adverse event (SAE)  
An SAE is classified as any untoward medical occurrence that, at any dose, meets any of the 
following criteria (a – f):  
a. Results in death.  
b. Is life-threatening. The term ‘life-threatening’ in the definition refers to an event in 
which the patient was 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.  
c. Requires inpatient hospitalization or prolongation of existing hospitalization.  
A hospitalization or prolongation of hospitalization will not be regarded as an SAE if 
at least one of the following exceptions is met:  
–The admission results in a hospital stay of less than 12 hours.  
–The admission is pre-planned.

1. The existence of a highly likely alternative explanation, e.g. mechanical bleeding at 
surgical site.  
or  
2. Non-plausibility, e.g. the patient is struck by an automobile when there is no 
indication that the drug caused disorientation that may have caused the event; cancer 
developing a few days after the first drug administration.  
An assessment of “yes” indicates that that the AE is reasonably associated with the use of the 
study treatment.  
Important factors to be considered in assessing the relationship of the AE to study treatment 
include:  
• 
The temporal sequence from drug administration: The event should occur after the 
drug is given. The length of time from drug exposure to event should be evaluated in 
the clinical context of the event.   
• 
Recovery on drug discontinuation (de-challenge), recurrence on drug re-introduction  
(re-challenge): Patient’s response after de-challenge or re-challenge should be 
considered in view of the usual clinical course of the event in question.   
• 
Underlying, concomitant, intercurrent diseases:   
Each event should be evaluated in the context of the natural history and course of the 
disease being treated and any other disease the patient may have.   
• 
Concomitant medication or treatment:   
The other drugs the patient is taking or the treatment the patient receives should be 
examined to determine whether any of them might have caused the event in question.   
• 
Known response pattern for this class of drug: Clinical/preclinical.   
• 
Exposure to physical and/or mental stresses: The exposure to stress might induce 
adverse changes in the recipient and provide a logical and better explanation for the 
event.   
• 
The pharmacology and pharmacokinetics of the study treatment:   
The pharmacokinetic properties (absorption, distribution, metabolism and excretion) 
of the study treatment, coupled with the individual patient’s pharmacodynamics 
should be considered.   
• 
The assessment is not possible.   
Causal relationship to protocol-required procedure(s)  
The assessment of a possible causal relationship between the AE and protocol-required 
procedure(s) is based on the question whether there was a “reasonable causal relationship” to 
protocol-required procedure(s).  
Possible answers are “yes” or “no”.

9.5.1.4  
Assessments and documentation of adverse events  
AEs observed, mentioned upon open questioning by a member of the investigator team or 
spontaneously reported by the patient will be documented in the patient’s records and on the 
appropriate CRF. AEs will be documented in an event-based manner, using NCI-CTCAE 
version 4.03 guidelines. In addition, since the NCI-CTCAE may not adequately capture the 
severity of new corneal epitheliopathy, an alternative severity grading system for ocular 
adverse drug reactions will be used (see Table 2-6 and Table 2-7).  
9.5.1.5  
Reporting of serious adverse events  
The definition of SAEs is given in Section 9.5.1.1. Each SAE must be followed up until 
resolution or stabilization by submission of updated reports to the designated recipient.  
It is not mandatory to report new SAEs occurring after the protocol-defined observation 
period, however, at the investigator’s discretion these may be reported if considered 
potentially relevant. In such cases, the SAEs will be processed by the sponsor according to all 
applicable regulations.

All investigators will be thoroughly instructed and trained on all relevant aspects of the 
investigator’s reporting obligations for SAEs. This information, including all relevant contact 
details, is summarized in the investigator site file. This information will be updated as 
needed.  
The investigator must report immediately (within 24 hours of the investigator’s awareness) all 
SAEs occurring during the observation period defined in Section 9.5.1.3 to the Yale Center 
for Clinical Investigation (YCCI) Project Manager as detailed in the instructions for SAE 
reporting included in the Investigator File. For this, an AE page in the CRF as well as the 
complementary pages provided in the Investigator File must be completed for each SAE.   
SAEs occurring after the protocol-defined observation period will be processed by the 
sponsor according to all applicable regulations.  
If disease progression leads to signs and symptoms that meet the criteria for seriousness (see 
Section 9.5.1.1), the associated signs and symptoms should be reported as SAE, not the 
underlying cause (i.e. “progressive disease” should not be recorded as SAE). In this case, 
disease progression should be mentioned on the SAE form as “alternative explanation”. 
If a new primary malignancy is noted at any time before end of active follow-up, it must be 
reported as an SAE, whether or not it is assessed as related to study treatment.  
For documentation of laboratory findings as SAE, please refer to Section 9.5.3.1.  
Notification of the IECs / IRBs  
Notification of the IECs / IRBs and Bayer Health Care about all relevant events (e.g. SAEs, 
suspected, unexpected, serious adverse reactions [SUSARs]) will be performed by the 
sponsor and/or by the investigator according to all applicable regulations and local policies.  
All SAEs, whether originating at Yale or at collaborating sites, meeting the criteria for prompt 
reporting will be reported to the Yale University Human Investigation Committee (HIC) as 
per IRB Policy 710.  
The Yale University HIC prompt reporting criteria are: Unexpected (in terms of nature, 
specificity, severity, or frequency) AND related or possibly related to participation in the 
research AND the research places subjects or others at greater risk of harm (including 
physical, psychological, economic, legal, or social harm) than was previously known or 
recognized. Collaborating sites should report adverse events to their local IRB per 
institutional policy.

Notification of the authorities  
The processing and reporting of all relevant events (e.g. SAEs, SUSARs) to the authorities 
will be done by the sponsor according to all applicable regulations.  
Sponsor’s notification of the investigational site  
The sponsor will inform all investigational sites about reported relevant events (e.g. SUSARs) 
according to all applicable regulations.  
9.5.1.5  
Expected adverse events  
For this study, the applicable reference document for anetumab ravtansine is the most current 
version of the IB.  
Overview listings of frequent events that have occurred so far in the clinical development are 
shown in the current IB. If relevant new safety information is identified, the information will 
be integrated into an update of the IB and distributed to all participating sites.  
The expectedness of AEs will be determined by the sponsor according to the applicable 
reference document and according to all local regulations.  
9.5.1.6  
Adverse events of special safety interest  
Anetumab ravtansine is an investigational drug and current knowledge of the AEs associated 
with this compound is limited.  
As with any new chemical entity, there is always potential for unexpected AEs, including 
hypersensitivity reactions.  
Corneal disorders are considered as AEs of special interest. Specific dose modification 
schemes are defined in Section 7.3.2.1. An alternative severity grading system for ocular 
adverse drug reactions will be used in addition to NCI-CTCAE version 4.03 criteria, since the 
NCI-CTCAE may not adequately capture the severity of these novel adverse reactions (see 
Table 2-6 and Table 2-7).  
There is no need to report corneal toxicities as SAEs unless they meet the criteria for an SAE 
as defined in Section 9.5.1.1; however these events will need to be closely monitored and 
reviewed, and documented timely and accurately both in source data and on the CRF. Details 
of ophthalmologic examination will be documented on the “ophthalmologic examination” 
CRF page and in case AEs occur, also on “AE” CRF page, ensuring the reporting 
terminology used on those pages matches and reflects the source.  
9.5.2  Pregnancies  
The investigator must report to the sponsor any pregnancy occurring in a female study patient 
during her participation in this study. The outcome of the pregnancy should be followed up 
carefully, and any outcome of the mother and the child at delivery should be reported.  
The child’s health should be followed up until 4 weeks after birth.

For a pregnancy in the partner of a male study patient, all efforts will be made to obtain 
similar information on course and outcome, subject to the partner’s consent.  
For all reports, the forms provided are to be used. The investigator should submit them within 
the same timelines as an SAE.  
9.5.3  
Further safety  
9.5.3.1  
Laboratory evaluations  
Safety laboratory analyses will be performed locally according to the schedule summarized in 
the flow chart of Section 9.1.  
Complete blood count: Hemoglobin, hematocrit, platelet count, white blood cell count 
(WBC). WBC must include differential including neutrophil, lymphocyte, monocyte, 
basophil, and eosinophil counts.  
Electrolyte and chemistry panel: sodium, potassium, chloride, bicarbonate, calcium, 
phosphorus, glucose (fasting or random/unspecified), AST, ALT, gamma-glutamyl 
transferase (GGT), bilirubin (total and direct), ALP, uric acid, total protein, albumin, 
lipase, amylase, lactic dehydrogenase (LDH), blood urea nitrogen (BUN) or urea, and 
creatinine.  
Coagulation panel: PTT, and PT or PT-INR.  
Urinalysis: Only dipstick test will be done, and complete urinalysis (e.g. microscopic 
analysis of the urine sediment) will only be done if the dipstick results are indicative 
or clinically indicated.  
Serum pregnancy test in WOCBP. Test should be repeated at least every 6 weeks until 
safety follow-up visit. Postmenopausal women who have not had periods for more 
than 1 year without an alternative medical cause or surgically sterilized women will 
not be required to undergo a serum pregnancy test (this information should be 
recorded under medical history on the CRF).  
eGFR according to the MDRD abbreviated formula (see Appendix 16.6).  
An isolated laboratory abnormality that meets the criteria for a CTCAE Grade 4 classification 
is not reportable as an SAE, unless the investigator assesses that the event meets standard 
International Conference on Harmonization (ICH) criteria for an SAE (see SAE definition in 
Section 9.5.1.1). All laboratory abnormalities, including CTCAE Grade 4 abnormalities, will 
be documented on the laboratory CRF.  
9.5.3.2  
Physical examination   
Physical examinations will be performed according to the schedule summarized in the flow 
chart of Section 9.1. Clinically significant abnormal physical examination findings are 
recorded either as medical history or as AEs (see Section 9.5.1.1).  
Complete physical examination  
Complete physical examination of all organ systems per usual standards.

Brief physical examination  
Brief physical examination includes, but is not limited to, review of organ systems and 
physical areas of symptomatic concern or investigator’s degree of suspicion for any 
abnormality. After Cycle 1, brief physical examinations are only mandatory on Day 1 of each 
cycle and are optional as per local practice at Day 8 and Day 15 visits.  
9.5.3.3  
ECOG Performance Status  
Change of ECOG PS will be measured for safety reason; grading definitions are given in 
Appendix 16.1. ECOG PS will be assessed at prescreening, full screening, on Day 1 of each 
cycle and at safety follow-up visit (see flow chart in Section 9.1).  
9.5.3.4  
Vital signs  
Body weight, height, heart rate, blood pressure, body temperature, and respiratory rate will be 
assessed according to the schedule summarized in the flow chart of Section 9.1. Any 
clinically relevant measurements or changes are to be reported as AEs (e.g. weight gain or 
loss, hypertension, tachycardia, bradycardia, etc.).  
9.5.3.5  
12-lead ECG  
12-lead ECGs will be performed according to the schedule summarized in the flow chart of 
Section 9.1. The overall interpretation of the ECG (normal/abnormal, clinical relevance) and 
the ECG diagnosis will be documented in the source documents and on the CRF. This review 
should be completed by a qualified physician and signed and dated at the time of review.  
9.5.3.6  
Cardiac function  
Cardiac function test is mandatory. It will be measured by EchoCG or MUGA scan at full 
screening and on C2D1, C4D1, and afterwards at the investigator’s discretion based on 
clinical need (see flow chart in Section 9.1). EchoCG shall be performed instead of MUGA 
when local regulations do not permit the use of MUGA as requested per protocol schedule.  
9.5.3.7  
Ophthalmologic examinations  
Corneal toxicity has been identified as a TEAE of special interest for which a causal 
relationship with anetumab ravtansine has been deemed probable by the investigators in 
Phase I trial. A detailed ophthalmologic examination (visual acuity [BCVA according to 
ETDRS, or Snellen, or Landolt C or other charts], IOP, dry eye test [Schirmer test] and slit 
lamp) will be done for all patients during full screening within 3 weeks before the start of 
study treatment (see flow chart in Section 9.1). Visual acuity test and slit lamp examination 
will be repeated before infusion in every cycle except C1D1, and at safety follow-up visit, or 
more frequently at investigator’s discretion (important to refer to Table 2-6 and Table 2-
7).   
IOP measurement is to be repeated during anetumab ravtansine therapy if the patient receives 
steroid eye drops as treatment for eye toxicity. IOP measurements should be repeated at two 
weeks and six weeks after starting topical corticosteroids for any subjects who are treated 
with topical corticosteroids for more than ten days. If neither the two week nor the six week 
IOP evaluation reveal elevated IOP (i.e., IOP increase by ≥ 7 mmHg), the frequency of IOP

evaluations can be reduced to every 4 months.  If IOP evaluation reveals an elevated IOP, 
appropriate medical management should be initiated with follow-up appropriate for the 
elevation in IOP. Changes in IOP should be managed by the investigator. The remedial 
therapy should be chosen at investigator’s discretion or according to the institutional 
standards; therapeutic measures can include modification of the type or posology of topical 
steroid eye drop, initiation of topical IOP lowering drugs and any other therapeutic options 
according to the local SoC. Ophthalmological monitoring should be maintained until the IOP 
has returned to normal values.  
Dry eye (Schirmer) tests will be repeated at C1D1 (if screening period Schirmer test is 
conducted within 7 days of starting study treatment, the test does not need to be repeated at 
C1D1), and on treatment prior to C4D1 and C7D1. Schirmer tests may be repeated more 
frequently during treatment at investigator’s discretion (e.g. in case of eye dryness during 
anetumab ravtansine therapy).   
During treatment, ophthalmologic examination can be done up to 7 days before anetumab 
ravtansine infusion.  
9.6  
Other procedures and variables  
9.6.1  Biomarkers  
Preclinical and Phase I evidence suggests that mesothelin expression (or expression level 
above a certain threshold) in human tumors may be required for binding, internalization, and 
anti-tumor activity of anetumab ravtansine. All patients will have formalin-fixed, paraffin-
embedded (FFPE) tumor samples available for IHC determination of mesothelin expression 
at prescreening as a potential predictive biomarker (see also flow chart in Section 9.1). In the 
absence of archival tissue, fresh biopsies may be used if deemed safe by the investigator and 
there is no additional risk for the patient in the investigator’s judgement. Only patients whose 
tumors express mesothelin at staining intensity of moderate (2+) or stronger (3+) in at least 
30% of tumor cells will participate further in this study. Mesothelin levels will be determined 
using an IHC assay (clone SP74).  
In addition to obligatory measurement of mesothelin expression levels, biomarker plasma 
(from whole blood) will be collected on C1D1 pre-dose, C6D1 (+/- 1 cycle), and at end of 
treatment if possible, to be banked for future correlative research.  
Exploratory biomarker analysis may also be performed using additional tumor tissue for 
future studies of scientific interest; these might include alterations in tumor-associated genes 
and to perform gene expression analysis.   
The exploratory biomarkers may include, but are not limited to, DNA sequencing of tumor-
associated genes and gene expression profiling. Next generation sequencing (NGS), and 
RNA, protein or miRNA expression analysis may be performed.  
In addition to the biomarkers listed above, other biomarkers deemed relevant to gain further 
knowledge about the pathomechanism of the disease or about the drug (i.e. mode of action-

related effect or safety of the drug) and/or the pathomechanism of the disease may be 
measured, based on newly emerging data from other ongoing studies and/or literature data.  
Details on the collection, processing, storage and shipment of biomarker samples will be 
provided in separate documents (e.g. sample handling sheets or lab manual).  
9.7  
Appropriateness of procedures / measurements  
The efficacy assessments used in the study include those considered SoC to evaluate 
antitumor activity in patients with advanced or metastatic pancreatic cancer.   
The safety assessments are appropriate and standard to monitor safety and assess toxicity.  
Appropriateness of RECIST criteria. RECIST 1.1 criteria, designed to assess response of 
solid tumors is highly appropriate for determination of the primary endpoint of RR.  
10.  
Statistical methods and determination of sample size  
10.1  
General considerations  
Statistical analysis will be performed using SAS version 9.2 or later; the version used will be 
specified in the SAP.  
In general, continuous variables will be summarized using number of non-missing values (n), 
number of missing values, means, standard deviations, medians, maximum, minimum, and 
interquartile range.  
Ordinal variables will be summarized using n, number of missing values, medians, maximum, 
minimum, and interquartile range.  
Categorical variables will be summarized using n, number of missing values, and 
percentages.  
Time-to-event variables will be summarized using Kaplan-Meier estimates.  
Further details on the statistical analyses will be provided in the SAP.  
10.2  
Variables and planned statistical analyses  
10.2.1  
Population characteristics  
Population characteristics (see Section 9.3) will be reported by summary statistics and 
listings. Further details will be described in the SAP.  
10.2.2  
Primary efficacy variable  
Response rate is defined as time from start of treatment until disease progression (according 
to RECIST, per blinded radiology review) or death. Patients not experiencing death or 
progression will be censored at the last tumor assessment.  
Additional details, including additional censoring rules, will be described in the SAP.

19-September-2018 
Version 4.0  
Page:  64 of 77  
  
 
10.2.2.1 Primary efficacy analysis  
The primary efficacy analysis tests the following hypotheses:  
H0: In patients with advanced or metastatic pancreatic cancer overexpressing mesothelin and 
pretreated with prior chemotherapy, a response per RECIST under treatment with anetumab 
ravtansine at 6.5 mg/kg Q3W would not be seen.  
versus   
HA: In patients with advanced or metastatic pancreatic cancer overexpressing mesothelin and 
pretreated with prior chemotherapy, a response per RECIST under treatment with anetumab 
ravtansine at 6.5 mg/kg Q3W would be seen.  
The minimax, Simon 2-stage design testing 5% null hypothesis versus a 21% alternative 
requires a maximum of 30 patients.  If there are no patients exhibiting any response among 
the first 20 then the trial will terminate early.  If there is at least one response among the first 
20 then the trial will accrue an additional 10 patients for a maximum of 30. Four or more 
responses out of 30 will reject the null hypothesis in favor of the 21% response alternative.  
These criteria have significance level (alpha) 0.1 and power 90%.  The probability of 
stopping early is 36% if the response rate is 5% or lower.  The expected sample size is 26.4.  
Sensitivity analyses will be performed, including analyses to assess the impact of missing 
data and the possibility of survivorship and selection biases. Further details will be described 
in the SAP.  
10.2.2.2  
Safety variables  
Safety variables will include AEs, laboratory changes (hematology, clinical chemistry and 
clinical urinalysis), abnormal findings in physical examination, changes in ECOG PS, 
changes in vital signs (weight, blood pressure, heart rate, respiratory rate, and body 
temperature), changes in ECG, changes in cardiac function test (EchoCG or MUGA scan) and 
changes in ophthalmologic examinations (visual acuity and slit lamp examination, IOP and 
Schirmer test if repeated). All AEs whether considered drug-related or not, will be reported 
on the CRF with a diagnosis, start/stop dates, action taken, whether treatment was 
discontinued, any corrective measures taken, outcome and other possible causes. For all 
events, the relationship to treatment and the intensity of the event according to CTCAE v4.03 
will be determined by the investigator, using the terms and definitions given in Section 
9.5.1.2.  
Definition of treatment-emergent safety events  
The treatment period for safety purposes is defined as the start of study treatment until 
30 days after the last day of study treatment.  
Treatment-emergent safety events (e.g. TEAEs) are safety events which arise or worsen 
during the treatment period.  
Additional details will be described in the SAP.

Safety analysis  
The final safety analysis will be performed at the time of the final primary endpoint analysis..  
All enrolled patients who receive at least 1 dose of treatment will be valid for safety analysis.  
All observations pertinent to the safety of treatment will be recorded on the CRF and included 
in the Clinical Study Report (CSR).  
Descriptive summary tables will be presented for all safety parameters. All TEAEs, 
treatment-emergent and hematological/biochemical toxicities based on laboratory 
measurements, as well as drug-related AEs and SAEs, will be graded by CTCAE v4.03 and 
categorized by MedDRA.  
Results of physical examination, vital signs, ECG, and other safety variables as described in 
the SAP will be summarized. The number (%) of patients who discontinue study drug due to 
AE or for whom a dose reduction or interruption is needed due to AE will also be 
summarized.  
10.2.3  
Other variables  
  
10.2.3.1  
Biomarker variables  
An analysis of mesothelin expression levels in all patients evaluated for mesothelin 
expression will be performed.  Biomarker parameters that may predict response, e.g. 
mesothelin expression levels in tumors and in plasma, may be analyzed by patient, and 
associated with tumor response using descriptive statistics, if appropriate. The association 
between biomarker and selected safety, efficacy, or PK parameters may be graphically 
displayed. Further exploratory statistical analyses may be performed. Biomarker variables 
and analyses will be further described in the SAP.  
10.3  Planned interim analyses  
An interim analysis for RR at the time 20 patients are evaluable will be performed.  
11.  
Data handling and quality assurance  
11.1  
Data recording  
The data collection tool for this study will be via the Yale OnCore system.  Data forms will 
be available within the trial webpage and all data will be entered remotely via web access.  
Non-Yale sites will have access to OnCore for this purpose.  
11.1.1  Source documentation  
The site must implement processes to ensure availability of all required source 
documentation. A source document checklist (not part of this protocol) will be used at the site 
to identify the source data for key data points collected and the monitor will work with the 
site to complete this.

Version 4.0  
Page:  66 of 77  
  
 
It is the expectation of the sponsor that all data entered into the CRF has source 
documentation available at the site.  
11.1.2  Data recorded from prescreening and full screening failures  
At minimum, the following data should be recorded in the CRF:  
• 
Demographic information (patient number; year of birth / age; sex; if applicable race / 
ethnicity)  
• 
Date of all informed consent(s)that were signed  
• 
Relevant inclusion/exclusion criteria for prescreening and for full study (if available)  
• 
Reason for premature discontinuation  
• 
Result of mesothelin overexpression level testing (if available)  
• 
Date of last visit.  
These data will be transferred to the respective database.  
For prescreening failures who experienced an SAE related to prescreening procedures, and 
for full screening failures who had signed consent for full study and who experienced an 
SAE, the following data should be collected in the CRF in addition to the data specified 
above:  
• 
All information related to the SAE such as:   
o The SAE itself  
o Concomitant medication 
o Medical history 
o Other information needed for SAE complementary page.  
11.2  
Monitoring  
The study principal investigator and YCCI are responsible for monitoring the performance of 
all of the participating sites.  This will be performed by conducting a study site initiation visit, 
as well as regularly scheduled monitoring visits and/or remote monitoring throughout the life 
of the protocol. At the end of the trial, the monitor will then perform a study site close-out 
visit at all participating sites.   
YCCI will utilize their institution’s initiation, monitoring and close-out visit reports. 
Following each site visit, a visit report will be generated containing information on site 
activities, and a summary of pertinent points and action items together with a copy of the 
follow-up letter will be sent to each investigative site.   
During these monitoring visits, some of the items that will be reviewed are the following:   
• 
Training of the sites   
• 
Site personnel qualifications to participate in the trial

• 
That study related documents are current   
• 
That regulatory compliance is accomplished   
• 
That each subject has signed the informed consent   
• 
That the current and approved protocol is complied with (including reporting and 
logging of all protocol deviations)   
• 
That all SAEs and AEs have been reported to the local regulatory and Ethics/IRB 
Committees, YCCI, and Bayer as appropriate   
• 
That source documentation matches CRFs   
• 
That required procedures for study drug accountability, distribution, and storage are 
followed.   
YCCI will document the required study monitoring activities in a Study Monitoring Plan.  
11.3  
Audit and inspection  
To ensure compliance with GCP and regulatory requirements, the YCCI Office of Quality  
Assurance and Training will audit the trial at least annually or as determined by the Yale 
Cancer Center DSMC. The overall principal investigator, study coordinator and/or data 
manager may request access to all source documents and other study documentation for 
onsite or remote monitoring, audit or inspection.  
Involvement in this study as a participating investigator implies acceptance of potential audits 
or inspections, including source data verification, by representatives designated by the 
Principal Investigator or Yale. The purpose of these audits or inspections is to examine study-
related activities and documents to determine whether these activities were conducted and 
data were recorded, analyzed, and accurately reported in accordance with the protocol, 
institutional policy, and any applicable regulatory requirements.  
In addition, inspections by regulatory health authority representatives and IEC(s)/IRB(s) are 
possible. The investigator should notify the sponsor immediately of any such inspection.  
The Sponsor-Investigator/institution and participating site investigators/institutions agree to 
allow the auditor or inspector direct access to all relevant documents and allocate their time 
and the time of their staff to the auditor/inspector to discuss findings and any issues. Audits 
and inspections may occur at any time during or after completion of the study.  
11.4  
Archiving  
Essential documents shall be archived safely and securely in such a way that ensures that they 
are readily available upon authorities’ request.  
Patient (hospital) files including tumor images will be archived according to local regulations 
and in accordance with the maximum period of time permitted by the hospital, institution or 
private practice. Where the archiving procedures do not meet the minimum timelines required 
by the sponsor, alternative arrangements must be made to ensure the availability of the source 
documents for the required period.  
The reading institution will archive the data for at least 15 years.

The investigator/institution notifies the sponsor if the archival arrangements change (e.g. 
relocation or transfer of ownership).  
The investigator site file is not to be destroyed without the sponsor’s approval.  
The contract with the investigator/institution will contain all regulations relevant for the study 
center.  
12.  
Premature termination of the study  
The sponsor has the right to close this study (or, if applicable, individual segments thereof 
[e.g. treatment arms; dose steps; centers]) at any time, which may be due but not limited to 
the following reasons:   
• If risk-benefit ratio becomes unacceptable owing to, for example, 
o Safety findings from this study (e.g. SAEs)  
o Results of parallel clinical studies 
o Results of parallel animal studies  
(on e.g. toxicity, teratogenicity, carcinogenicity or reproduction toxicity).  
• 
If the study conduct (e.g. recruitment rate; dropout rate; data quality; protocol 
compliance) does not suggest a proper completion of the trial within a reasonable time 
frame.  
The investigator has the right to close his/her center at any time.  
For any of the above closures, the following applies:  
• 
Closures should occur only after consultation between involved parties. Final decision 
on the closure must be in writing.  
• 
All affected institutions (e.g. IEC(s)/IRB(s); competent authority(ies); study center; 
head of study center) must be informed as applicable according to local law.  
• 
All study materials (except documentation that has to remain stored at site) must be 
returned to the sponsor. The investigator will retain all other documents until 
notification is given by the sponsor for destruction.  
• 
In the event of a partial study closure, ongoing patients, including those in post-study 
follow-up, must be taken care of in an ethical manner.  
Details for individual patient's withdrawal can be found in Section 6.3.1.

GCP guidelines and the guiding principles detailed in the Declaration of Helsinki. The study 
will also be carried out in keeping with applicable local law(s) and regulation(s).  
Documented approval from appropriate IEC(s)/IRBs will be obtained for all participating 
centers/countries before start of the study, according to GCP, local laws, regulations and 
organizations. When necessary, an extension, amendment or renewal of the IEC/IRB 
approval must be obtained and also forwarded to the sponsor. The responsible unit (e.g. 
IEC/IRB, head of the study center/medical institution) must supply to the sponsor, upon 
request, a list of the IEC/IRB members involved in the vote and a statement to confirm that 
the IEC/IRB is organized and operates according to GCP and applicable laws and regulations.  
Strict adherence to all specifications laid down in this protocol is required for all aspects of 
study conduct; the investigator may not modify or alter the procedures described in this 
protocol.  
Modifications to the study protocol will not be implemented by either the sponsor or the 
investigator without agreement by both parties. However, the investigator or the sponsor may 
implement a deviation from, or a change of, the protocol to eliminate an immediate hazard(s) 
to the trial patients without prior IEC/IRB/sponsor approval/favorable opinion. As soon as 
possible, the implemented deviation or change, the reasons for it and if appropriate the 
proposed protocol amendment should be submitted to the IEC/IRB/head of medical 
institution/sponsor. Any deviations from the protocol must be explained and documented by 
the investigator.  
Details on discontinuation of the entire study or parts thereof can be found in Section 12.

Response assessment  
Tumor response will be evaluated in this study using the RECIST 1.1 criteria.  
Response Criteria  
Complete response (CR): Disappearance of all target lesions. Disappearance of all 
nontarget lesions and normalization of tumor marker level, if applicable. Any pathological 
lymph nodes (whether target or non-target) must have decreased in size to have a short axis 
of < 10 mm.  
Partial response (PR): At least a 30% decrease in the sum of diameters of target lesions 
taking as reference the baseline sum diameters. No appearance of new lesions. Non-target 
lesions must be stable or can be not evaluable.  
Progressive disease (PD): At least a 20% increase in the sum of diameters of target lesions, 
taking as reference the smallest sum on study = nadir (this includes the baseline sum if that is 
the smallest on study). In addition to the relative increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5 mm. For non-target lesions, unequivocal 
progression of existing lesions represents PD.  
Note: the appearance of one or more new lesions is also considered progression.  
Stable disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD, taking as reference the smallest sum diameters while on study.  
Table below provides an overview how the overall response is assessed.

Calculation of glomerular filtration rate by the Modification of Diet in 
Renal Disease formula  
In accordance with established nephrology practice and guidelines, renal function at baseline 
and throughout the study will be assessed by means of the estimated GFR, calculated using 
the abbreviated MDRD study formula.  
This equation of 4 variables (serum creatinine level, age, sex, and ethnicity) is recommended 
by the National Kidney Foundation for use in individuals 18 years or older. The formula can 
be found at the following website (47).  
Patients with a baseline GFR < 30 mL/min/1.73 m2 calculated by this method will not be 
allowed to participate in the study.
