TRIO030 Protocol v. 3.0 – Rationale for Amendment
TRIO030 protocol was amended due to the following reasons:

Enrollment difficulties faced by participating sites in some of the cohorts defined in the study

Updated data from the most current Investigator´s Brochure

Administrative changes, clarification and other minor edits
TRIO030 protocol was amended as follows:

Sections 1.3.1, 3.1, 4.1, 4.2, 5.3.2.1, 5.3.3, 5.3.4, 5.4.1, 5.4.2, 5.5.2, 6.3, 6.4.3, 6.4.5, 6.5.7.1, 
8.6, and Appendix 2: Wording modified to allow patients candidates for neoadjuvant therapy 
to participate on the trial, as long as patients and Investigators are willing to start such 
therapy once treatment with darolutamide is completed and to undergo a biopsy prior to 
starting neoadjuvant therapy. 

Sections 1.2 and 5.5.1: Sections have been updated as per safety data from Amendment 1 to 
Investigator’s Brochure version 3.0, dated 22-Dec-2017.

Sections 3.2, 6.3, and 6.5.7.1: Allowance of 2 cores for screening samples if 3 are not feasible.

Sections 3.1, 3.2, 6.1.2.2: Allowance of a minimum of 8 evaluable patients per cohort.

Sections 3.1, 6.3, and 6.4.1: Wording added to clarify that patients enrolled but never treated 
will be discontinued from study.

Section 3.3: Potential reasons for the premature termination of the study by the sponsor 
were added. 

Sections 4.1 and 4.2: Criterion modified to allow patients with T1 ≥ 1.0 cm.

Section 4.2: Modifications done on exclusion criteria related to previous or concurrent anti-
cancer treatments. 

Section 5.5.3: Conditions required to consider vasectomised male partner as a highly 
effective contraceptive method were added as a footnote.

Sections 6.3 and 6.4.3: Wording added to allow Pre-surgery visit to take place the same day 
as BC surgery/pre-NAST biopsy.

Section 6.4.3: Section was modified to request that laboratory safety tests are available and 
reviewed in the Pre-surgery visit before surgery is performed.

Section 8.5: Wording modified to perform interim review of data at given time points 
depending on the recruitment, for example once 20, around 35 and once all patients have 
been enrolled and undergone the EoS as per protocol.

Term darolutamide utilized throughout the protocol instead of ODM-201 for consistency with 
Investigator’s Brochure.

TRIO Project Team updated as per latest changes in its composition.


Term “patient” utilized throughout the protocol to refer to women participating in the study, 
instead of other terms (e.g. “subject”).

Abbreviation change (HR+ to substitute ER+ where applicable).

Acronym “NAST” was utilized throughout the protocol to refer to Neoadjuvant Systemic 
Therapy.

“Pre-NAST biopsy” utilized throughout the protocol to refer to biopsy to be performed prior 
to start of neoadjuvant treatment in patients who are candidates for such therapy.

Figure 1: Surgery visit name changed to “BC sugery/pre-NAST biopsy”.

Table 2: Schedule of Procedures: footnotes 1 and 12 revised to clarify the timelines for tumor 
samples collection at screening.

Protocol Title
A Presurgical Tissue-Acquisition Study to Evaluate Molecular Alterations in Human Breast 
Cancer Tissue Following Short-Term Exposure to the Androgen Receptor Antagonist
Darolutamide (ODM-201)
Protocol #
TRIO030
Study Duration
Enrollment is expected to run over a 12-month period approximately. The overall study is 
expected to last around 14 months (from First Patient In until Last Patient Last Visit).
Sponsor/Study 
Chair
This is a TRIO-sponsored study which will be chaired by Dr. Dennis Slamon (Professor of 
Medicine, Chief, Division of Hematology-Oncology, UCLA's Department of Medicine, CA, 
USA). The study is financially supported by Bayer.
Participating 
Investigators/Sites
Approximately 20 sites in North America and Europe will participate in the study. 
Target Population
Women with early-stage breast cancer (BC) candidates for surgery as primary treatment 
modality or candidates for neoadjuvant treatment who accept to undergo a second biopsy 
before starting such therapy.
Background and 
Rationale
Despite progresses made in diagnostic techniques and treatments for BC, there is still a 
significant number of patients undergoing treatment for early BC (EBC) who will relapse or 
patients with advanced BC that do not respond or progress to their treatments. The medical 
need for new and potentially more active and better tolerated agents in BC remains very 
high.
Endocrine treatment is one of the strategies with a major therapeutic value in patients with 
estrogen-receptor (ER) positive tumors. Although, the role of ER and progesterone receptor 
(PgR) is well established in BC as predictive and prognostic factors, little is known about the 
clinical significance of the androgen receptor (AR). Preclinical studies show that the 
androgen signaling pathway plays a critical role in the development of normal and malignant 
breast tissue. AR is expressed in approximately 80% and 60% of primary and metastatic BC, 
respectively. Its expression varies across the different subtypes, approximately 84-95% in 
ER+ tumors, 50-63% in ER-/HER2+ cases and 10-53% in TNBC. 
In ER+ BC it has been suggested that acquired resistance to antiestrogen therapies could 
result from adaptation from estrogen dependence to androgen dependence. Recently, 
clinical reports of AR antagonism have been promising, especially in TNBC. Bicalutamide and 
enzalutamide have been tested in phase II trials in TNBC and have shown promising clinical 
activity. 
These developments in combination with an improved understanding of AR signaling in 
different BC subtypes led to the renewed interest in targeting AR. However, the value of AR
antagonists in the management of BC, the molecular alterations that occur after exposure to 
these agents and whether there are biomarkers useful to predict their effectiveness, still 
need to be fully elucidated. Increased understanding of AR blockade and its potential value 
in different BC subtypes and clinical testing of newer and more potent AR antagonists like 
darolutamide, is thus timely and necessary. 
The current study will enroll EBC female patients with differing BC subtypes, with the intent 
of characterizing the molecular alterations in BC tissue before and after a short-term 
exposure to darolutamide. Darolutamide is a new AR antagonist, that thus far has been 
found to be very well-tolerated.
Studying the biological mechanisms in which darolutamide targets the AR in BC will be 
crucial in understanding its potential role in this disease, as well as providing the foundation 
for the rational development of darolutamide in the disease. Molecular profiling of tumor 
samples before and after darolutamide treatment may permit the identification of patients 
likely or unlikely to respond to the agent based on the biological and molecular 
characteristics of their tumors. 
Since it is essential to evaluate the molecular effects of darolutamide in tumors not exposed 
to chemotherapy or radiation, patients with untreated primary breast tumors amenable to a

Page 12
pre-treatment biopsy followed by a post-darolutamide sample at definitive surgery or 
prior to starting neoadjuvant systemic therapy (NAST) represent an ideal population to 
study. Although no direct benefit from the treatment with darolutamide is expected in the 
participating patients, the good tolerability and favourable safety profile of darolutamide at 
the selected dose, the proposed brief duration of treatment, and the fact that patients 
enrolled in the study will not be required to undergo any delay in definitive surgery/start of 
neoadjuvant therapy, should ensure the safety and ethical set-up of the trial.
Objectives 
Primary Objective:
To identify the molecular alterations that occur in human BC tissue, following short-term 
exposure to darolutamide in female patients with EBC.
Secondary Objectives:
To evaluate the safety and tolerability of short-term exposure to darolutamide in female 
patients with EBC.
Study Design
This is a multi-center, open-label, tissue-acquisition study involving up to 60 patients with 
early-stage invasive BC. 
Patients with (a) suspicion of invasive BC based on clinical and/or radiological findings, or 
(b) a confirmation of invasive BC based on previous cytology/core/incisional biopsy will be 
invited to participate in the study: (a) In cases without pathological confirmation of BC 
diagnosis, signature of patient informed consent form (PICF) before BC confirmation 
biopsy is preferred to allow the collection of study-specific biopsies to be conducted.  
(b) For patients who have already had a confirmatory biopsy, they may also participate in 
the study if willing to undergo a subsequent study-specific biopsy procedure according to 
the protocol or if their diagnostic biopsy has been done according to the protocol 
requirements (in terms of number of cores/tissue, fresh frozen collection, etc). 
At time of PICF signature, patients will be registered in the study. Primary tumor samples will 
be collected by core needle biopsy or incisional biopsy (excisional biopsy will not be 
allowed). A minimum of three cores of tissue using a 14-gauge needle is recommended (or 
equivalent amount with an incisional biopsy). Two of the cores will be snap-frozen and the 
third one should be prepared in paraffin according to site’s practice. In cases, it is not
possible to provide enough material, collection of 2 cores (or equivalent amount with 
incisional biopsy) will be acceptable: one core will be snap-frozen and the other one will be 
prepared in paraffin.
To be able to assess the molecular alterations after darolutamide exposure in different BC 
subtypes, patients being either triple-negative, or HR+/HER2 negative, or HER2 positive will 
be enrolled in the study (up to 20 patients with each of these subtypes, with an acceptable 
minimum of 8 evaluable patients in each cohort if enrollment of recommended 20 patients 
is not feasible for any reason).
Eligible patients will be enrolled and receive darolutamide at a dose of 600 mg (2 × 300 mg 
tablets) b.i.d. to a daily dose of 1,200 mg. Protocol treatment should start within 5 days of 
enrollment, and within 42 days of the study-specific tumor sample collection. Minimum 
duration of treatment with darolutamide is 14 days with a recommended maximum 
duration of 21 days. It is recommended that the BC surgery/pre-NAST biopsy date is defined 
prior to starting protocol treatment. The start date of darolutamide (Day 1) will be derived 
as minus 14 to 21 days from the scheduled BC surgery/pre-NAST biopsy date. If for some 
reason BC surgery/pre-NAST biopsy takes place more than 21 days after treatment start (e.g. 
scheduling issues, delays, etc.), it is acceptable that patient receives darolutamide for more 
than 21 days and up to a maximum of 35 days. Patient should continue protocol treatment 
until the day prior to BC surgery/pre-NAST biopsy or “nil per os” (npo) is ordered. In these 
cases it is strongly recommended to have BC surgery/pre-NAST biopsy performed as soon as 
possible after 21 days of treatment are completed. Also, in any case that treatment is 
extended beyond 21 days, TRIO Medical Monitor should be contacted to discuss 
continuation of treatment and the need for assessments.
At the time of BC surgery (if NAST is not indicated), or before NAST starts if indicated, BC 
tissue will be collected: two cores (or an equivalent amount of tissue), one fresh-frozen and

one paraffin-embedded.

Protocol Treatment
Darolutamide will be given at a dose of 600 mg (2 × 300 mg tablets) b.i.d. corresponding to a 
daily dose of 1,200 mg.
The following timelines will be considered for darolutamide administration:

Darolutamide shall be administered starting within 5 days of enrollment.

No more than 42 days should elapse from the day the study-specific tumor sample 
is taken at initial diagnosis (or in a subsequent procedure) to the day of the first 
intake of darolutamide.

Minimum duration of treatment will be 14 days prior to BC surgery or to the pre-
NAST biopsy (if NAST is indicated).

A maximum duration of 21 days of treatment is recommended. . It is recommended 
that the date of BC surgery/pre-NAST biopsy is defined prior to starting protocol 
treatment. The start date of darolutamide (Day 1) will be derived as minus 14 to 21 
days from  the scheduled BC surgery/pre-NAST biopsy date.

Treatment will be given until the day prior to the BC surgery, or the day before pre-
NAST biopsy or when npo is ordered, whichever occurs first. 

If for some reason BC surgery/pre-NAST biopsy takes place more than 21 days after 
treatment start, it is acceptable that patient receives darolutamide for more than 
21 days and up to a maxiumum of 35 days; patient should continue protocol 
treatment until the day prior to BC surgery/pre-NAST biopsy or npo is ordered. In 
these cases it is strongly recommended to have BC surgery/pre-NAST biopsy done 
as soon as possible after 21 days of treatment are completed. Also, in any case 
that treatment is extended beyond 21 days, TRIO Medical Monitor should be 
contacted to discuss continuation of treatment and the need for assessments.

Statistical Methods 
Up to 60 patients (a minimum of 8 evaluable patients and up to 20 patients in each breast 
cancer subtype: triple-negative, HR+/HER2 negative, HER2 positive) will be required for the 
performance of the molecular studies and possible hypothesis generation. 
A patient will be considered evaluable if the following criteria are met:
Minimum duration of treatment with darolutamide is of 14 days, with a minimum of 10 
consecutive days of treatment prior to the definitive BC surgery/pre-NAST biopsy. 
Mandatory tumor tissue is collected at screening and at BC surgery/pre-NAST biopsy
according to the protocol and submitted to the central lab.
Adequacy for molecular assessment of the tumor tissue collected before and after the 
protocol treatment initiation. The adequacy will be evaluated by the central lab.
Assessment of patient evaluability, safety and distribution of patients with respect to 
hormone receptor status and HER2 status will be performed by the Study Steering 
Committee (SSC) at given time points depending on the recruitment, primarily planned once 
20, around 35 and once all patients have been enrolled and undergone the EoS per protocol. 
This will allow for the SSC to ascertain that the appropriate number of evaluable patients is 
being accrued, that more or less patients may be required, or in the extreme case, that 
accrual should close if the patient evaluability rate is very low and/or safety concerns arise.
The SSC will define the evaluability of patients that discontinue treatment more than 3 days 
before surgery: molecular analyses may be taken into consideration for the decision about 
the evaluability of such patients.
Study Populations
Intention-to-treat (ITT) Population: the ITT population includes all patients who are 
enrolled in the study regardless of whether they have been treated or not.
Safety Population: the Safety population includes all patients who have taken at least one

1. BACKGROUND AND RATIONALE
1.1
Disease Overview
Breast cancer (BC) is the second most common cancer in the world and by far, the most frequent 
cancer among women.1 In the United States (US), approximately 246,000 new BC cases and 40,000 
deaths due to this disease are expected to occur in women during 2016. This represents 29% of all 
cancers diagnosed annually in women and 14% of deaths due to cancer annually in women.2
BC is a highly heterogeneous disease with marked differences regarding molecular, biological and 
clinical features. Molecular subtypes have been described with corresponding differences in 
prognosis and response to treatments. The current classification is based on the expression of 
estrogen and progesterone receptors (ER and PgR respectively) and HER2, and BC are broadly 
divided into three subtypes: HR+/HER2 negative, HER2+ and triple negative BC (TNBC). The 
characterization of which subtype of BC a patient has, allows to adapt the different treatment 
modalities due to their predictive value and has also prognostic implications. 
Despite progress made in diagnostic techniques and treatments for BC, there is still a significant 
number of patients undergoing treatment for early BC (EBC) who will relapse or patients with 
advanced BC whose tumor will not respond to standard treatments or progress after them. The 
medical need for new and potentially more active and better tolerated agents in BC remains very 
high. 
1.2
Investigational Medicinal Product Overview
Darolutamide (ODM-201) is a new AR antagonist that is being jointly developed by Bayer AG and 
Orion Corporation for the treatment of castration-resistant prostate cancer (CRPC). As of the version 
date of this protocol, it has not been marketed or authorized to be marketed in any country.
Darolutamide potently inhibits testosterone binding to AR and retains antagonistic properties in cells 
expressing increased AR levels better than bicalutamide. Darolutamide diminishes AR-signaling by 
inhibiting testosterone mediated nuclear localization of AR more efficiently than bicalutamide. It
shows antiandrogenic and antitumor activity in in vitro and in vivo models of CRPC and in clinical 
studies in patients with metastatic CRPC (mCRPC).
Darolutamide is a 1:1 mixture of 2 pharmacologically active diastereomers: ORM-16497 and ORM-
16555 which are able to interconvert. Steady-state plasma concentrations of darolutamide are
reached by 7 days of repeated dosing. The mean elimination half-life is in the range of 11.5-16.1 
hours.
Data from an in vivo mass balance study in rats suggests that about two-thirds of oral darolutamide
dose is excreted in feces and the remaining amount in urine. After a single dose, excretion is almost 
complete by 48 hours post-dose.
In general, the potential for darolutamide to inhibit CYP reaction pathways in vitro in human liver 
microsomes is low. The CYP450 induction potential of darolutamide was evaluated in vitro in 
primary cultures of human hepatocytes and a risk of weak to moderate CYP3A4 induction by 
darolutamide was observed.
In vivo data from study 17726 indicates that co-administration of rifampicin -a strong CYP3A4 
inducer- (600 mg, fasted state) and a single dose of darolutamide (600 mg; 2 tablets of 300 mg) 
together with food, resulted in a 3-and 2-fold decrease of AUC (0-72) and Cmax of darolutamide to 
28% and 48% respectively. Therefore, repeated co-administration of strong or moderate CYP3A4 
inducers (e.g. carbamazepine, phenobarbital, St. John's Wort) with darolutamide is expected to 
reduce darolutamide plasma concentrations. The concomitant intake of these substances during 
study treatment should hence be avoided.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 18
In vitro data indicate that darolutamide is a substrate of P-glycoprotein (P-gp) and Breast cancer 
resistance protein (BCRP). Therefore administration of strong inhibitors of P-gp (e.g., verapamil, 
dronedarone) and BCRP (e.g., pantoprazole, eltrombopaq) may increase the plasma concentrations 
of Darolutamide and should be used with caution. However, in vivo data from Study 17726 showed 
that co-administration of itraconazole –a strong CYP3A4 and P-gp inhibitor- (200 mg) and a single 
dose of darolutamide (600 mg; 2 tablets of 300 mg) together with food, resulted in a 1.7-fold 
increase in AUC (0-72) and a 1.4-fold increase of C max of darolutamide. This indicates that co-
administration of darolutamide with a strong CYP3A4 or P-gp inhibitor does not result in a clinically 
relevant increase of darolutamide (ODM-201) plasma concentrations.
Plasma concentration of drugs that are sensitive P-gp or BCRP substrates might be increased by 
darolutamide. Medicinal products that are sensitive substrates for P-gp (e.g., digoxin) or BCRP (e.g.,
methotrexate) should be used with caution when co-administered with darolutamide. In vivo data 
shows that the administration of 600 mg of darolutamide b.i.d. over 4 days prior to administration 
of a single dose of 5 mg rosuvastatin, a BCRP substrate, together with food resulted in a 5.2-fold 
increase in mean exposure (AUC) of rosuvastatin and a 4.9-fold increase in maximum serum 
concentration (Cmax). This indicates that co-administration of darolutamide can increase the plasma 
concentrations of other concomitant BCRP substrates (e.g. methotrexate, sulfasalazine, fluvastatin, 
atorvastatin).
As of 04 January 2017, darolutamide has been given to 173 patients with CRPC. Until now, 
darolutamide has been studied in 6 clinical studies. The majority of the phase I/II studies were 
conducted in mCRPC patients. One phase I study was conducted in healthy male volunteers with a 
single administration of darolutamide. Non-metastatic CRPC patients are being investigated in an
ongoing phase III study (ARAMIS trial).
Antitumor activity of darolutamide was evaluated in 3 studies in mCRPC. They have shown that 
darolutamide has antitumor activity at all dose levels as evaluated by Prostate Specific Antigen 
(PSA), circulating tumor cells and soft and bone lesion imaging. PSA decline ≥ 50% was observed at 
12 weeks in 74% of chemotherapy-naïve patients treated with darolutamide.
Darolutamide has thus far been found to be well-tolerated and to have negligible blood-brain barrier 
penetration. The integrated safety data from clinical trials showed 93.9% of patients developed at 
least 1 adverse event (AE) and grade 3 or higher AEs were reported in 28% of patients. The most 
common AEs have been fatigue in 26.8% of patients and back pain in 22% of patients. The most 
common AEs considered related to protocol treatment by the Investigator have been fatigue (9.8%) 
and hot flush (4.3%). The majority of AEs were classified as grade 1 (59.7% of the events) and grade 
2 (31.2% of the events). Of the serious adverse events (SAEs) reported in clinical trials (27.4 %) none 
of them was considered related to the protocol treatment by the Investigator or by the Sponsor.
In summary, the results indicate that darolutamide exhibits a good safety and tolerability profile and 
promising antitumor activity in men with CRPC.
Additional information on the clinical efficacy, safety, pharmacology of darolutamide is provided in 
the darolutamide Investigator brochure (IB).  
1.3
Rationale
1.3.1
Rationale for Conducting the Study
The androgen receptor (AR) is a member of the nuclear steroid hormone receptor family, which also 
includes ER and PgR. These are critical components of signaling pathways and regulate gene 
expression. AR expression in BC has long been noted and is the most common nuclear hormone 
receptor. AR is expressed in approximately 80% and 60% of primary and metastatic BC, respectively.3
Its expression varies across the different subtypes, approximately 84-95% in ER+ tumors, 50-63% in 
ER-/HER2+ cases and 10-53% in TNBC.3

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 19
The role of AR in BC still needs to be fully elucidated, differently from the well-known ER and PgR. 
Preclinical studies show that the androgen signaling pathway plays a critical role in the development 
of normal and malignant breast tissue. Epidemiologic studies suggest that increased levels of 
circulating androgens are associated with an increased risk for BC, primarily ER/PgR-positive BC.4
AR expression in ER+ BC associates with improved outcomes, but AR seems to be oncogenic in the 
tamoxifen-resistant setting.3 Approximately 30 to 50% of all ER+ BC tumors display de novo
resistance to standard endocrine therapies and most metastatic ER+ tumors do eventually acquire 
resistance over time.5 AR positivity increases resistance to tamoxifen in BC models in vitro and in 
vivo.6 Thus, it is possible that acquired resistance to antiestrogen therapies could result from 
adaptation from estrogen dependence to androgen dependence.7  
In the case of TNBC, signaling through the AR may play a role in pathogenesis. Studies which have 
focused on AR expression in TNBC have provided conflicting results in regards to the prognostic 
value of AR expression.8 While some studies suggest that AR expression is a favorable prognostic 
factor in patients with TNBC, others suggest that it predicts reduced survival in early TNBC.8, 9
Irrespective of this, AR might represent a new target in TNBC, which has so far a worse prognosis
and very limited standard therapeutic options, none of them targeted.
As a result of these findings, AR has emerged as a potential useful marker for the further 
subclassification of BC and as a potential therapeutic target.
Modulation of AR signaling, either inhibitory or stimulatory, has previously been explored in BC with 
somewhat contrasting results. Androgen therapy has historically been used but largely abandoned in 
the 1970s due to its toxicity and the emergence of ER-directed therapies.
More recently, clinical reports of AR antagonism have been promising, especially in TNBC. 
Bicalutamide has been assessed in a phase II, single-arm trial in AR+, ER- advanced BC, and showed 
clinical benefit rate of 19% with a good safety profile.10 Some newer drugs like enzalutamide, have 
also been tested in TNBC. A phase II study in AR+ TNBC proved that this therapy was well-tolerated 
and showed promising clinical activity in selected patients.11
These developments in combination with an improved understanding of AR signaling in different BC
subtypes led to the renewed interest in targeting AR. However, the value of AR antagonists in the 
management of BC, the molecular alterations that occur after exposure to these agents and whether 
there are biomarkers useful to predict their effectiveness, still need to be fully elucidated. Increased 
understanding of AR blockade and its potential value in different BC subtypes and clinical testing of 
newer and more potent AR antagonists like darolutamide, is thus timely and necessary.
Translational Oncology Research Laboratories (TORL, at University of California Los Angeles, US) has 
conducted cell viability studies in 49 BC cell lines exposed to different concentrations of 
darolutamide. The studies have shown that cell lines belonging to each of the three BC subtypes 
(HR+, HER2+, TN) responded different to darolutamide. Responses are mainly seen in cell lines 
expressing AR but also in some lines that lack AR expression, suggesting that AR expression may not 
be the only biomarker predicting response to darolutamide (unpublished).
The current study will enroll EBC female patients with differing BC subtypes, with the intent of 
characterizing the molecular alterations in BC tissue before and after short-term exposure to the 
antiandrogen darolutamide. Studying the biological mechanisms in which darolutamide targets the 
AR in BC will be crucial in understanding its potential role in this disease, as well as providing the 
foundation for the rational development of darolutamide in the disease. Such information may 
suggest that darolutamide be combined with other modalities; for example, if treatment with the 
drug is discovered to affect multiple signaling pathways. Molecular profiling of tumor samples before 
and after darolutamide treatment may permit the identification of patients likely or unlikely to 
respond to the agent based on the biological and molecular characteristics of their tumors. Since it is 
essential to evaluate the molecular effects of darolutamide in tumors not previously exposed to 
chemotherapy or radiation, patients with untreated primary breast tumors amenable to a pre-

Page 20
treatment biopsy followed by a post-darolutamide sample at definitive surgery or prior to starting 
neoadjuvant systemic therapy (NAST) represent an ideal population to study. Male patients will not 
be enrolled due to pathological and biological differences in male breast cancer.12
Although no direct benefit from the treatment with darolutamide is expected in the participating 
patients, the good tolerability and favourable safety profile of darolutamide at the selected dose, the 
proposed brief duration of treatment, and the fact that patients enrolled in the study will not be 
required to undergo any delay in definitive surgery or start of NAST if indicated, should ensure the 
safety and ethical set-up of the trial.
1.3.2
Rationale for Regimen and Dose Selection
In TRIO030, darolutamide will be given at a dose of 600 mg (2 × 300 mg tablets) b.i.d. to a daily dose 
of 1,200 mg. Darolutamide should be taken with food since exposure and Cmax are reduced in fasting 
conditions. 
Darolutamide has been studied in doses ranging from 100 mg to 900 mg b.i.d. in a phase I dose 
escalation and dose finding study. No dose-limiting toxicities were observed in this study and the 
maximum tolerated dose was not reached. Systemic exposure to darolutamide increased dose-
proportionally in the dosing range from 100 to 700 mg b.i.d. At 900 mg b.i.d. dose there was no 
further increase in Cmax or AUC observed when compared to 700 mg b.i.d. Based on the results of 
this phase I study, the recommended dose was 600 mg b.i.d. for further development. At the dose of 
600 mg b.i.d. most AEs were grade 1-2 and assessed by the Investigators as not related to protocol 
treatment. 
Therefore, the dose selected in the study is considered as safe and is the dose that is being used in 
current darolutamide trials in patients with other primary cancer sites.
2. OBJECTIVES
2.1
Primary Objective

To identify the molecular alterations that occur in human BC tissue, following short-term 
exposure to darolutamide in female patients with EBC.
2.2
Secondary Objectives

To evaluate the safety and tolerability of short-term exposure to darolutamide in female 
patients with EBC.
3. STUDY DESIGN
3.1
Overall Study Design and Plan: Description
This is a multi-center, open-label, tissue-acquisition study involving up to 60 patients with early-
stage invasive BC. 
Female patients with (a) suspicion of invasive BC based on clinical and/or radiological findings, or (b) 
those who have a confirmation of invasive BC based on previous cytology/core/incisional biopsy will 
be invited to participate in the study:
(a) In cases without pathological confirmation of BC diagnosis, signature of patient informed 
consent form (PICF) before BC confirmation biopsy is preferred to allow the collection of study-
specific biopsies to be conducted. 

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 21
(b) For patients who have already had a confirmatory biopsy, they may also participate in the 
study if willing to undergo a subsequent study-specific biopsy procedure according to the 
protocol or if their diagnostic biopsy has been done according to the protocol requirements (in 
terms of number of cores/tissue, fresh frozen collection, etc.; refer to section 6.5.7.1).
At time of PICF signature, patients will be registered in the study. Primary tumor samples will be 
collected by core needle biopsy or incisional biopsy (excisional biopsy will not be allowed). A 
minimum of three cores of tissue using a 14-gauge needle is recommended (or equivalent amount 
with an incisional biopsy). Two of the cores will be snap-frozen and the third one should be prepared 
in paraffin according to site’s practice. In cases that it is not possible to provide enough material, 
collection of 2 cores (or equivalent amount with incisional biopsy) will be acceptable; one core will 
be snap-frozen and the other one will be prepared in paraffin. 
After all screening procedures and confirmation of eligibility, patients will be enrolled and will begin 
intake of darolutamide. To be able to assess the molecular alterations after darolutamide exposure 
in different BC subtypes, female patients being either triple-negative, or HR+/HER2 negative, or 
HER2 positive will be enrolled in the study. Up to 20 patients with each of these subtypes will be 
included (refer to section 6.1.2.2 for further details on the enrollment according to BC subtype). 
However, a minimum of 8 evaluable patients in each cohort is considered acceptable if enrollment of 
20 patients is not feasible within a cohort for any reason.
Eligible patients will be enrolled and receive darolutamide at a dose of 600 mg (2 × 300 mg tablets) 
b.i.d. corresponding to a daily dose of 1,200 mg. Protocol treatment should start within 5 days of 
enrollment and within 42 days of the study-specific tumor sample collection. Patients enrolled, but 
not treated, will be discontinued from study and managed as per the site’s standard of care (SoC).
Minimum duration of treatment with darolutamide is 14 days with a recommended maximum 
duration up to 21 days. It is recommended that the BC surgery/pre-NAST biopsy date is defined prior 
to starting protocol treatment. The start date of darolutamide (Day 1) will be derived as minus 14 to 
21 days from the scheduled BC surgery/pre-NAST biopsy date. Treatment will be taken until the day 
prior to the BC surgery (if NAST is not indicated) or the day before NAST starts if indicated; or when 
the patient is ordered to stop all oral intake, whichever occurs first (refer to section 5.3.2.1). If for 
some reason surgery takes place more than 21 days after treatment start (e.g. surgery scheduling 
issues, surgery delays, etc.) it is acceptable that patient receives darolutamide for more than 21 days 
and up to a maximum of 35 days. Patient should continue protocol treatment until the day prior to 
BC surgery/pre-NAST biopsy or “nil per os” (npo) is ordered. In these cases it is strongly 
recommended to have BC surgery/pre-NAST biopsy performed as soon as possible after 21 days of 
treatment are completed.
At the time of BC surgery (if NAST is not indicated), or before NAST starts if indicated, BC tissue will 
be collected: two cores (or an equivalent amount of tissue), one fresh-frozen and one paraffin-
embedded.
End of Study (EoS) visit will occur 30 days (+/- 3 days) after the patient's last intake of darolutamide.
In case protocol treatment-related AEs/SAEs ongoing at the time of the EoS visit, monitoring of these 
events will continue as clinically indicated until (a) the events have resolved or (b) the events have 
reached a status which, in the Investigator’s opinion, is unlikely to resolve due to the nature of the 
condition and/or the patient’s underlying disease. 
Treatment for BC including NAST (if applicable), definitive surgery, and adjuvant therapy will be at 
the Investigator’s discretion.

BC= Breast cancer
* In cases with absence of a pathological confirmation of BC diagnosis, PICF signature prior to the biopsy for BC
confirmation is preferred. For patients who already had such confirmatory biopsy, they may also participate in the study if 
willing to undergo a subsequent study-specific biopsy procedure according to the protocol or if their diagnostic biopsy has 
been done according to the protocol requirements (in terms of number of cores/tissue, fresh frozen collection, etc.).
3.2
Number of Patients and Investigational Sites
Up to 60 patients will be enrolled in the study, from approximately 20 sites in North America and 
Europe, with an acceptable minimum of 8 evaluable patients in each if enrollment of 20 patients is 
not feasible within a cohort for any reason. The list of Investigators participating in the study will be 
maintained in TRIO’s Clinical Trial Management System. 
3.3
Study End 
The study will end once the last patient undergoes the EoS visit and all data required for the analyses
have been observed, collected and cleaned. The trial may be prematurely terminated at any time by 
Ethics Committees (EC)/Institutional Review Boards (IRB), competent authorities, or the sponsor. 
Potential reasons for premature termination of the study by the sponsor are (not exhaustive):

Regulatory authority decision

Change in opinion of the EC/IRB

Drug safety concerns

Manufacturer’s decision to discontinue development of darolutamide

Inability to run the study because of operational issues (e.g., low recruitment)
If the study is prematurely terminated or discontinued, TRIO will promptly notify the Investigators 
and all other relevant parties.
4. PATIENT SELECTION
Patients can be enrolled in the study only if the eligibility criteria are met. This study can fulfill its 
objectives only if appropriate patients are enrolled. Patients who fail to meet all inclusion criteria or 
fulfill at least one exclusion criteria cannot be enrolled in the study. The sponsor will not grant any 
eligibility waivers.

5. TREATMENT
5.1
Protocol Treatment: Darolutamide
Darolutamide is the only protocol treatment in the trial and is considered an Investigational 
Medicinal Product (IMP). Darolutamide will be supplied to the investigational sites as 300 mg tablets, 
free of charge.
For the purpose of this trial, the Single Reference Document to be used for darolutamide is the IB.
5.2
Protocol Treatment Management
5.2.1
Packaging and Labeling
Darolutamide is provided as coated immediate-release 0.3 g (300 mg) tablets, in a high-density 
polyethylene (HDPE) white opaque plastic bottle containing 140 tablets.
Clinical supplies will be affixed with a clinical label in accordance with applicable regulatory 
requirements, and include a statement regarding its limitation to investigational use only. 
5.2.2
Storage and Accountability
Study drugs must be stored according to labeled requirements, at room temperature not exceeding 
30°C in a secure, limited-access location. Receipt and dispensing of trial medication must be 
recorded by an authorized person at the site. Clinical supplies may not be used for any purpose 
other than that stated in the protocol.
The Investigator/designee is responsible for keeping accurate records of the clinical supplies 
received from the Sponsor or designee, the amount administered or dispensed to and returned by 
the patients, and the amount remaining at the conclusion of the trial.
TRIO will provide appropriate documents that must be completed for drug accountability and 
destruction/return.
5.2.3
Drug Return/Destruction
Patients must return all unused medication and empty containers to the Investigator/designee. 
Unused/expired darolutamide should be destroyed locally (where requirements permit) once 
accountability is performed and drug supplies are reconciled. Procedures for proper disposal of 
darolutamide should be applied according to standards established at each site.

No specific pre-medication is required. Based on the available data on latest vesion of IB, there are 
no special warnings and precautions for use of darolutamide.
5.3.2
Standard Treatment Schedule
5.3.2.1 Dosage and Administration
Darolutamide will be given at a dose of 600 mg (2 × 300 mg tablets) b.i.d. to a daily dose of 
1,200 mg.
The following timelines will be considered for darolutamide administration (refer to Figure 1: Study 
Schema):

Darolutamide shall be administered starting within 5 days of enrollment.

No more than 42 days should elapse from the day the study-specific tumor sample is taken 
at initial diagnosis (or in a subsequent procedure) to the day of the first intake of 
darolutamide (Note: for patients who already had their initial diagnostic biopsy prior to 
registration and this procedure has been done according to the protocol requirements, the 
42- day window should be counted from the date of such biopsy).

Minimum duration of treatment will be 14 days prior to BC surgery or to the pre-NAST 
biopsy (if NAST is indicated) (Note: a day of treatment is considered as any day where the 
patient takes any darolutamide intake)

A maximum duration of 21 days of treatment is recommended. It is recommended that the 
date of BC surgery/pre-NAST biopsy is defined prior to starting protocol treatment. The start 
date of darolutamide (Day 1) will be derived as minus 14 to 21 days from  the scheduled BC 
surgery/pre-NAST biopsy date.

Treatment will be given until the day prior to the BC surgery, or the day before pre-NAST 
biopsy or when npo is ordered, whichever occurs first. 

If for some reason BC surgery/pre-NAST biopsy takes place more than 21 days after 
treatment start, it is acceptable that patient receives darolutamide for more than 21 days 
and up to a maximum of 35 days; patient should continue protocol treatment until the day 
prior to BC surgery/pre-NAST biopsy or npo is ordered. In these cases it is strongly 
recommended to have BC surgery/pre-NAST biopsy done as soon as possible after 21 days of 
treatment are completed. Also, in any case that treatment is extended beyond 21 days, TRIO 
Medical Monitor should be contacted to discuss continuation of treatment and the need for 
assessments.

The first day of darolutamide administration in the study is considered Day 1. On or prior to 
Day 1 the patient will be provided with a bottle with 140 tablets containing 300 mg of 
darolutamide each (enough for 35 days of treatment at a daily dose of 1,200 mg). Patient 
will be instructed that the last protocol treatment intake should be the one in the morning 
of the Pre-surgery visit. The last darolutamide intake will be on the day prior to BC surgery, 
or the day before pre-NAST biopsy when the Pre-surgery visit should occur. Exceptions to 
this rule are when patient is ordered to stop oral intake before the day prior to BC 
surgery/pre-NAST biopsy, when BC surgery/pre-NAST biopsy is planned for a Monday or the 
day following a holiday, or in case that performing Pre-surgery visit on the same day of BC 
surgery/pre-NAST biopsy is required by site due to logistical reasons or patient’s/physician’s 
convenience (refer to section 6.4.3 for guidance). 
Darolutamide should be taken approximately at the same time each day, twice a day. It is 
recommended that darolutamide be taken with food; recommendation is to take it with breakfast 
and dinner each day. Patients will ingest darolutamide whole tablets with water. No tablet should be 
ingested if it is broken, cracked, or otherwise not intact.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 27
If the patient misses an intake or vomits following darolutamide administration, the missed/vomited
dose should be skipped and the patient should take the next intake when scheduled. No “make-up 
dose” or increased dosing should occur.
If a patient accidentally or intentionally takes a higher daily dose than the one recommended per
protocol and up to 1,800 mg (i.e. up to 6 × 300 mg tablets), protocol treatment should continue as 
scheduled without any dose reduction or skip. For example, if by mistake the patient takes 4 tablets 
in the first daily intake she can still take 2 tablets in the second daily intake since a total daily dose of 
1,800 mg is not exceeded. The Medical Monitor should be contacted for any dose taken that 
exceeds 1,800 mg daily.
5.3.2.2 Treatment Compliance
The administration of the protocol treatment should be recorded in the appropriate sections of the 
electronic case report form (eCRF).
Additionally, treatment compliance will be assessed at each visit that may occur during treatment 
phase (see section 6.4.2) and at Pre-surgery visit, and it should be properly documented in source 
documents. Patients will complete a diary (Appendix 2) to document their daily intakes. They will be 
instructed to return all unused drugs (partially used and empty containers) and their diary at each 
visit during the treatment period (if any) and at Pre-surgery visit. Site staff will perform 
accountability of the returned drug and will assess compliance of the patient. Site staff must ensure 
that the patient clearly understands the directions for self-medication and follows the schedule
adequately.
5.3.3
Protocol Treatment Discontinuation
Patients are treated until the day before BC surgery/pre-NAST biopsy (if NAST will be given), or when 
patient is ordered to stop oral intake, whichever occurs first. 
The Investigator will also discontinue protocol treatment if any of the following conditions is met:

Intercurrent illness or a change in patient´s condition or unacceptable toxicity that warrants 
protocol treatment discontinuation according to Investigator’s judgment

Any event, condition, criterion which would warrant discontinuation of darolutamide as per 
section 5.4, including Grade 3 or higher protocol-treatment related AE

Any event, condition, reason which would warrant darolutamide to be held for more than 
the maximum acceptable delay of 7 consecutive days

Patient receives non-protocol anticancer therapy at any time during the protocol treatment

Patient’s decision to withdraw protocol treatment

Lost to follow up

Death

Pregnancy 

Investigator’s decision

Discontinuation of the study by the sponsor (refer to section 3.3)
The reason and date of protocol treatment discontinuation for all patients will be documented in the 
eCRF (e.g. AE, lost to follow-up, etc.). The Investigator will attempt to complete all discharge 
procedures at the time a patient is discontinued from the study including an assessment of the AEs, 
collect all study-related materials from the patient (i.e. patient diary), and will complete the EoS
form. Patients are free to discontinue their participation in the study at any time, without prejudice 
to further treatment.

Surgery and (Neo) Adjuvant Systemic Therapy
BC surgery, NAST and post surgical BC treatments are left at the discretion of the Investigator and 
are not considered protocol treatments.
5.4
Adverse Events Management and Treatment Schedule Adjustments 
5.4.1
General Rules
Regular assessment and monitoring of AEs is required from PICF signature, throughout protocol
treatment period and at least up until surgery or BC pre-NAST biopsy if patient will receive NAST.
Toxicity will be assessed utilizing the National Cancer Institute Common Terminology Criteria for AEs
(NCI CTCAE) v4.03. For toxicities not specifically listed in the NCI CTCAE, the following grading will 
apply for assessing severity:

Grade 1: Mild

Grade 2: Moderate 

Grade 3: Severe

Grade 4: Life-threatening 

Grade 5: Death related to AE
Patients will be instructed to notify their physician immediately for any and all AEs.
Doses of protocol treatment may be modified (delayed or reduced) in case of clinically significant 
toxicities that are considered by the Investigator to be related to protocol treatment, according to 
the guidance in section 5.4.2. Assessment of causality (chronology, confounding factors, 
concomitant medications, diagnostic tests, and previous experience with the protocol treatment)
should be conducted by the Investigator prior to dose modification and/or delay whenever possible.
All dose modifications should be based on the AE requiring the greatest modification and should be 
properly documented in source documents and the eCRF.
5.4.2
Guidance for Darolutamide Dose Modifications
A patient who experiences a treatment-related Grade 3 or higher AE must be withdrawn from 
protocol treatment and should proceed to surgery/pre-NAST biopsy, and undergo EoS visit.
In the case of a grade 1-2 treatment-related AE, the Investigator should contact the Medical Monitor 
in case it is considered that a dose reduction or treatment hold is required due to the related AE.
Refer to Table 1: Dose Modifications.

5.5
Concomitant Medications and Procedures
Concomitant medications and procedures to be documented in patients’ medical sources and 
collected in eCRF include any medication or therapeutic procedure (e.g. prescription drugs, over-the-
counter drugs, herbal/homeopathic remedies, nutritional supplements, blood transfusions, etc.) 
used by a patient from 7 days prior to enrollment until the EoS visit.
Patients will be instructed to consult with the Investigator before taking any medications (including 
over-the-counter medications).  
Supportive medications may be provided prophylactically or therapeutically per Investigator
discretion.
Any concomitant treatment not listed in the section 5.5.2 is considered permitted in the study and 
may be prescribed as clinically appropriate during the study.
Concomitant therapies will be assessed at all visits and must be recorded on the appropriate eCRF
according to the rules in section 6.5.4.
5.5.1
Precautions – Drug Interactions

Drugs metabolized via CYP3A4 enzyme: Darolutamide may decrease the plasma 
concentrations of concomitantly given drugs which are mainly metabolized via CYP3A4 
enzyme (e.g., simvastatin, verapamil, dronedarone). Although the clinical significance of this 
potential interaction is not fully known, the concomitant intake of these substances during 
study treatment should be avoided. In case patients must continue receiving them, they
should be monitored for signs of decreased efficacy of these concomitant medications.
In vivo data from study 17726 indicates that co-administration of rifampicin -a strong 
CYP3A4 inducer- resulted in a significant decrease of darolutamide plasma concentrations.
Therefore, repeated co-administration of strong or moderate CYP3A4 inducers (e.g. 
carbamazepine, phenobarbital, St. John's Wort) with darolutamide is expected to reduce 
darolutamide plasma concentrations. Thus, the concomitant intake of these substances 
during study treatment should also be avoided.

P-gp and BCRP inhibitors/substrates: In vitro data indicate that darolutamide is a substrate 
of P-gp and BCRP. Therefore administration of strong inhibitors of P-gp (e.g. verapamil,

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 30
dronedarone) and BCRP (e.g., pantoprazole, eltrombopaq) may increase the plasma 
concentrations of darolutamide and should be used with caution. Despite this fact, in vivo
data from study 17726 showed that co-administration of darolutamide with itraconazole -a 
strong CYP3A4 and P-gp inhibitor- does not result in a clinically relevant increase of 
darolutamide plasma concentrations. In any case, caution is recommended.
Plasma concentration of drugs that are sensitive P-gp or BCRP substrates might be increased
by darolutamide. Therefore sensitive substrates for P-gp (e.g., digoxin) should be used with 
caution when co-administered with darolutamide. Co-administration of darolutamide can 
also increase the plasma concentrations of other concomitant BCRP substrates (e.g. 
methotrexate, sulfasalazine, fluvastatin, atorvastatin). Therefore, the patients should be 
closely monitored for signs and symptoms of increased exposure to such BCRP substrates.
Dose modification of BCRP substrates should be considered based on the prescriber
information or such compounds should be avoided.
Refer to the section “Drug Development and Drug Interactions: Table of Substrates, Inhibitors and 
Inducers” of the FDA website for a list of potential interactions (as of the date of this protocol
available at: 
http://www.fda.gov/Drugs/DevelopmentApprovalProcess/DevelopmentResources/DrugInteractions
Labeling/ucm093664.htm
5.5.2
Prohibited Treatments and/or Procedures
Patients are prohibited from receiving the following therapies from the time of PICF signature until 
BC surgery/pre-NAST biopsy:

Investigational agents other than the protocol treatment.

Any additional standard or investigational anticancer agents, such as chemotherapy, 
immunotherapy, targeted/biologic therapy, endocrine therapy, etc., even if utilized as 
treatment of non-cancer indications. Darolutamide must be permanently discontinued upon 
initiation of a non-protocol standard or investigational antineoplastic therapy prior to BC 
surgery/pre-NAST biopsy.  
5.5.3
Contraception
WoCBP must agree to use acceptable non-hormonal contraceptive methods of birth control from 
the day of the screening pregnancy test up to 3 months after the last intake of protocol treatment. 
Refer to section 4.1 for the definition of WoCBP.
Acceptable forms of contraception are:
(1) pracZce absZnence† from heterosexual acZvity; 
OR 
(2) use (or have their partner use) acceptable contracepZon during heterosexual acZvity‡:  

Single method (one of the following is acceptable):
o
intrauterine device (IUD)
o
vasectomy of a female patient’s male partner¥

Combination method (requires use of two of the following):
o
diaphragm with spermicide (cannot be used in conjunction with cervical 
cap/spermicide)
o
cervical cap with spermicide (nulliparous women only)  

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 31
o
contraceptive sponge (nulliparous women only) 
o
male condom or female condom (cannot be used together)
†AbsZnence (relaZve to heterosexual acZvity) can be used as the sole method of contracepZon if it is 
consistently employed as the patient’s preferred and usual lifestyle and if considered acceptable by local 
regulatory agencies and Ethics Committees. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, 
post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception. 
‡ If a contraceptive method listed in this section is restricted by local regulations/guidelines, then it does not 
qualify as an acceptable method of contraception for patients participating at sites in this country/region.
¥ Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual 
partner of the WoCBP trial participant and that the vasectomised partner has received medical assessment of 
the surgical success.
6. SCHEDULE OF VISITS AND PROCEDURES
6.1
Patient Inclusion
6.1.1
Informed Consent
A written, dated and signed and freely given informed consent must be obtained prior to any study-
specific procedure.
Prior to any study-specific screening evaluation, the patient will be informed of the nature of the 
study and will be given pertinent information as to the intended purpose, possible benefits, and 
possible adverse experiences. The procedures and possible hazards to which the patient will be 
exposed will be explained.
An approved PICF will then be read and signed by the patient and, when required, a witness, and the 
Investigator or a person designated by the Investigator, as per local regulations. The patient will be 
provided with a copy of the signed PICF.
Patients with a suspicion of invasive BC based on clinical and/or radiological findings or those who 
have confirmation of invasive BC based on previous cytology/core/incisional biopsy deemed 
adequate candidate by the Investigator will be invited to participate in the study. In cases without 
pathological confirmation of BC diagnosis, signature of PICF before BC confirmation biopsy is an 
option to allow the collection of study-specific biopsies to be conducted at the same time as the 
diagnostic biopsy. For patients who have already had a confirmatory biopsy, they may participate in 
the study if their diagnostic biopsy has been done according to the protocol requirements. If their 
diagnostic biopsy has not been done according to the protocol requirement, they may also 
participate in the study if willing to undergo a subsequent study-specific biopsy procedure according 
to the protocol.
The patient may withdraw from the study at anytime without prejudicing future medical treatment. 
In any case, withdrawal should be documented on patient´s clinical records.
If a potential patient is illiterate or visually impaired, the Investigator must provide an impartial 
witness to read the PICF to the patient and must allow for questions. Thereafter, the patient and the 
witness must sign the PICF to attest that informed consent was freely given and understood. 
The PICF will include a statement by which the patient allows the Sponsor’s duly authorized 
personnel, the EC/IRB, and the regulatory authorities to have direct access to her data that will be 
processed according to the confidentiality regulations. 

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 32
If important new information becomes available that may be relevant to the patient’s consent and 
willingness to continue participation in the study, the PICF will be revised and submitted to IRB/IEC
and regulatory authorities (if applicable) for approval/favorable opinion. The new information will be 
then discussed with the patient in a timely manner and if she agrees to continue participation in the 
study, the revised PICF will be signed and dated and the patient will receive a copy.
In line with each local applicable regulations, the source should also support the documentation of 
the consent process, for each patient.
6.1.2
Registration and Enrollment 
6.1.2.1 Registration and Enrollment Procedures
At time of PICF signature patients will be registered in the study and then will undergo screening 
procedures. After all screening procedures and confirmation of eligibility, patients will be enrolled.
The following steps for registering and enrolling a patient are chronologically performed:
1.
The patient must provide written informed consent prior to performing any study-specific 
procedure not considered standard practice by the institution.
2.
The site will ask TRIO for patient’s registration immediately after signature of PICF. A unique 
registration number will be assigned to each patient in the study.
3.
The site will proceed to perform the protocol-required biopsy and all screening procedures 
according to section 6.3. Upon completion of screening procedures, the Investigator or 
his/her delegate will check if the patient meets all eligibility criteria: 
Patients who do not meet all eligibility criteria: sites will have the screen failure form 
completed in Remote Data Capture (RDC) with corresponding screen failure reason 
captured.
Patients who meet all eligibility criteria: sites will enter the screening data in RDC 
which will be reviewed centrally by TRIO. After the review of the eligibility criteria, 
TRIO may address, if necessary, some discrepancies that will have to be answered by 
the site. Once the eligibility central review is completed and discrepancies have been 
resolved (if applicable) TRIO will provide the confirmation that the patient is eligible 
and the site will be able to move forward with the patient’s enrollment in RDC. The 
site will receive a confirmation of enrollment. If the patient is deemed not eligible 
following the central eligibility review, the site will be asked to report the screen 
failure reason in RDC.
6.1.2.2 Enrollment According to BC Subtype
To be able to assess the molecular alterations after darolutamide exposure in different BC subtypes,
patients being either TNBC, or HR+/HER2-, or HER2+ will be enrolled in the study. Up to 20 patients 
with each of these subtypes will be included, with an acceptable minimum of 8 evaluable patients in 
each cohort if enrollment of recommended 20 patients is not feasible within a cohort for any reason.
Subtypes are defined based on local assessment as:

TNBC: ER, PgR and HER2 negative

HR+/HER2-: ER and/or PgR positive and HER2 negative

HER2+: HER2 positive, irrespective of ER/PgR status
ER and PgR positivity is defined according to the American Society of Clinical Oncology/College of 
American Pathologists Guideline Recommendations, as cases with ≥ 1% of tumor cell nuclei that are 
immunoreactive.13

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 33
HER2 positivity is defined as IHC 3+ and/or ISH amplification. HER2 negativity is defined as IHC 0-1 
and/or ISH non-amplification. In case HER2 status is Equivocal, patients will not be assigned to any 
cohort until central review is done and HER2 status is defined as either positive or negative.
Although patient inclusion in each of these three cohorts will be based on local testing, the central 
laboratory (TORL) will also test for ER, PgR and HER2. Assessment of distribution of patients with 
respect to centrally-assessed ER/PgR/HER2 will be done on an ongoing basis by the central 
laboratory and will also be performed by the Study Steering Committee (SSC) once the minimum 
requirement of patients in a cohort have undergone the EoS per protocol. This will allow the SSC to 
ascertain the rates of discordance between local and central testings and determine if more or less 
patients may be required in one or more cohort(s).
6.2
Study Participation Discontinuation
The Investigator has the right to discontinue a patient from protocol treatment or withdraw a 
patient from the study at any time. In addition, patients have the right to voluntarily discontinue 
protocol treatment or withdraw from the study at any time for any reason. 
6.2.1
Discontinuation from Protocol Treatment
Refer to section 5.3.3.
6.2.2
Discontinuation from Study Participation
The primary reason for study participation discontinuation should be documented on the eCRF. 
Reasons for patient´s discontinuation from the study include (but may not be limited to):

Patient is enrolled but does not receive protocol treatment for any reason

Patient completes the study 

Death

Consent withdrawal from entire study participation

Patient non-compliance

Lost to follow-up
Should a patient be enrolled, but has never started protocol treatment, she will be discontinued 
from the trial, and managed according to the site’s SoC.
Should a patient decide to withdraw consent, all efforts will be made to complete and report the 
observations as thoroughly as possible. The Investigator should schedule a visit with the patient, or 
contact the patient by telephone to establish as completely as possible the reason for the 
withdrawal. A complete final evaluation at the time of the patient’s withdrawal should be made with 
an explanation of why the patient is withdrawing from the study. After complete withdrawal of 
consent, no further study procedure is performed and no further data will be collected.
If a patient withdraws consent to the use of study-specific tumor samples:

The Investigator has the responsibility to notify TRIO immediately.

TRIO will ensure that the laboratory(ies) holding the samples is/are informed about the 
withdrawn consent immediately and that samples are either returned to the study site, or 
disposed of/destroyed by the central laboratory as per site’s request/local requirements, 
and the action documented by the central laboratory(ies). 
In the event that analysis/research has already been performed, TRIO or its representatives, in strict 
compliance with the applicable local regulations, should retain the results and associated data for 
regulatory reasons but these will not be used in any subsequent analyses.In the case a patient does

Note: All assessments should be performed within 3 days of the scheduled visit, unless otherwise specified. 
Footnotes:
1: Screening procedures (except PICF signature and screening tumor samples – see footnote 12) to be done within 28 days of enrollment, unless otherwise 
specified
2: Protocol treatment should begin within 5 days of enrollment and no more than 42 days after breast tissue collection. Treatment should last at least 14 
days, and no more than 35 days (recommended maximum duration 21 days). The need for a clinic visit during this period will depend on the duration of 
protocol treatment. If duration of treatment with ODM-201 is 14 to 21 days only the Pre-surgery visit needs to be performed after Day 1, unless otherwise 
clinically indicated. If ODM-201 is taken/expected to be taken for > 21 days (due to planned date of surgery/pre-NAST biopsy, delay in surgery/pre-NAST 
biopsy, etc.) a visit is required as close as possible to Day 21 +/- 3 days (except in case the pre-surgery visit is planned within Day 21 + / - 3 days).
3: The Pre-surgery visit should be performed the day before BC surgery or the day before BC pre-NAST biopsy is performed. The only exceptions should be:

(a) If for some reason the patient is ordered to stop all oral intakes earlier than the day prior to BC surgery/pre-NAST biopsy, the Pre-surgery visit should be 
scheduled on the day patient is ordered to stop oral intake; (b) In case the BC surgery/pre-NAST biopsy is planned for a Monday or the day following a 
holiday; in such cases the Pre-surgery visit should be done on a working day as close as possible to the BC surgery/pre-NAST biopsy (e.g. on a Friday if surgery 
is scheduled on Monday); or (c) In case that performing Pre-surgery visit on the same day of BC surgery/pre-NAST biopsy is required by site due to logistical 
reasons or patient’s/physician’s convenience. Refer to section 6.4.3 for further guidance about the Pre-surgery visit planning and procedures.
4: End of Study visit must be scheduled 30 days (+/- 3 days) after the last intake of darolutamide, even for patients who did not complete the minimum 14 
days of protocol treatment. The EoS will be the last study visit for patients. However, for patients experiencing protocol treatment-related AEs/SAEs that are 
ongoing at the time of the EoS visit, monitoring of these events will continue as clinically indicated until (a) the events have resolved or (b) the events have 
reached a status which, in the Investigator’s opinion, is unlikely to resolve due to the nature of the condition and/or the patient’s underlying disease. 
Frequency of visits will be according to Investigator’s judgment. 
5: There is no window to obtain the signed and dated PICF. Study-specific screening assessments not considered standard practice by the institution must 
start only once the PICF has been obtained. Registration takes place as soon as the patient signs the PICF. After screening procedures and if patient meets all 
eligibility criteria, enrollment will be done according to the process described in section 6.1.2.
6: Complete physical examination will include a complete assessment of body systems (i.e., general appearance, head, eyes, ears, nose, mouth, skin, heart, 
lungs, lymph nodes, gastrointestinal, genitourinary, skeletal, and neurologic). A complete examination of the breast and regional lymph nodes will also be 
done. 
7: Weight, height and blood pressure must be assessed and collected during screening. Afterwards they will be assessed (as well as other vital signs) 
according to the SoC.
8: Within 7 days of enrollment, only in WoCBP. 
9: Hematology: Hemoglobin, WBC, ANC, platelets. Blood chemistry: AST, ALT, total bilirubin, creatinine.
10: Concomitant medication and procedures include any medication or therapeutic procedure used by the patient within 7 days prior to enrollment until the 
EoS visit. Refer to section 6.5.4 for the reporting rules in the eCRF.
11: All unused drugs (partially used and empty containers) and the patient diary will be handed over to Investigators at each treatment visit (if any) and at the 
Pre-surgery visit.
12: Mandatory tissue collection:
-
Pre-treatment: A breast tumor sample must be collected at the time of the initial diagnosis (or in a subsequent procedure) either by core needle or 
incisional biopsy. Excisional biopsy will not be allowed. A minimum of 3 core biopsies using a 14-gauge needle (or the equivalent with an incisional 
biopsy) is recommended (2 fresh-frozen + 1 paraffin-embedded). In cases it is not possible to provide enough material, collection of 2 cores (or 
equivalent amount with incisional biopsy) will be acceptable: one core will be snap-frozen and the other one will be prepared in paraffin. For patients 
who already had such confirmatory biopsy prior to registration, there is no need to repeat it provided that their diagnostic biopsy has been done 
according to the protocol requirements (in terms of number of cores/tissue, fresh frozen collection, etc.). The screening tumor samples must be 
collected before start of treatment with darolutamide at the latest.

Study Visits and Assessments/Investigations
During all visits below, assessments should be done according to the Schedule of Procedures (section 
6.3).
6.4.1
Screening Period
The screening period starts with the registration (at time of PICF signature) and ends when the 
patient is enrolled (following eligibility central review and confirmation by TRIO) or screen failed. 
When scheduling the screening procedures it should be taken into account that treatment with 
darolutamide should start within 42 days of the study-specific tumor sample collection.
During the screening period the following assessments will be done:

Demographics, medical, surgical, disease history

Complete physical examination (including weight, height and blood pressure measurements)

ECOG PS

Serum pregnancy test: only in WoCBP, within 7 days of enrollment (refer to section 4.1 for 
the definition of WoCBP).

Laboratory assessments:
o Hematology: Hemoglobin, WBC, ANC and platelets
o Blood chemistry: AST, ALT, total bilirubin and creatinine

Adverse events assessment. For information on the assessment and collection of AEs refer 
to section 7 and to section 6.3

Concomitant medications

Tumor biopsy (refer to section 6.5.7)
Once all screening assessments have been conducted, the site will request enrollment of patients 
who meet all eligibility criteria through completion of all screening data in RDC (see section 6.1.2.1), 
and TRIO will review patient´s eligibility. No enrollment must take place before formal confirmation 
of eligibility is provided by TRIO to the site.
Once the patient is enrolled, she will be instructed to begin protocol treatment with darolutamide. If 
for some reason the patient does not start their study treatment, she will be discontinued from 
study, and managed as per site’s SoC. 
If for some reason laboratory tests are repeated between these tests done at screening and 
treatment start, the most recent measurement obtained prior to treatment start must be within the 
required values according to the inclusion criteria, to begin protocol treatment.
6.4.2
Treatment Period Visits
Refer to section 5.3.2.1 for timelines regarding protocol treatment. 
The need for a clinic visit during this period will depend on the duration of protocol treatment.
If duration of treatment with ODM-201 is 14 to 21 days, only the Pre-surgery visit needs to be 
performed after Day 1, unless otherwise clinically indicated.

CONFIDENTIAL
Page 39
If ODM-201 is taken/expected to be taken for > 21 days (due to planned date of BC surgery/pre-
NAST biopsy, delay in BC surgery/pre-NAST biopsy, etc.) a visit is required as close as possible to Day 
21 +/- 3 days (except in case the pre-surgery visit is planned within Day 21 + / - 3 days).
During the treatment period visit(s) (if any) the following will be assessed:

Symptom-directed physical examination 

ECOG PS

AEs 

Concomitant medication
6.4.3
Pre-surgery Visit
As a general rule, the Pre-surgery visit will be performed the day before BC surgery or the day before 
pre-NAST biopsy if NAST is indicated.* If after the Pre-surgery visit takes place, the BC surgery/pre-
NAST biopsy planned for the following day is delayed for any reason, the Investigator should contact 
the Medical Monitor to discuss about potential continuation of darolutamide after the Pre-surgery
visit.
During this visit the following assessments will be done:

Complete physical examination 

ECOG PS

Safety laboratory assessments:
o Hematology: Hemoglobin, WBC, ANC and platelets
o Blood chemistry: AST, ALT, total bilirubin and creatinine

AEs

Concomitant medication
Other pre-surgical assessments should be done according to the standard of care (SoC) at the site.
The only exceptions to scheduling the Pre-surgery visit on the day prior to BC surgery/pre-NAST 
biopsy will be in the following cases:
a.
If the patient is ordered to stop all oral intakes earlier than the day prior to BC 
surgery/pre-NAST biopsy. In such case the Pre-surgery visit should be scheduled on 
the day patient is ordered to stop oral intake and all test/assessments should be 
done at that point.
b.
In case the BC surgery/pre-NAST biopsy is planned for a Monday or the day 
following a holiday and the Pre-surgery visit cannot be scheduled the day prior to BC 
sugery/pre-NAST biopsy. In such case the following will be done:
The Pre-surgery visit should be done on a working day as close as possible to 
the BC surgery/pre-NAST biopsy (e.g. on a Friday if surgery is scheduled on 
Monday).
The patient will be instructed to continue with darolutamide intakes until 
the day prior to BC surgery/pre-NAST biopsy or when she is instructed to 
stop all oral intakes, whichever occurs first.

Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 40
c.
In case that performing Pre-surgery visit on the same day of BC surgery/pre-NAST 
biopsy is required by site due to logistical reasons or patient’s/physician’s 
convenience. In such case, it is acceptable that Pre-surgery visit is performed on the 
same day that BC surgery/pre-NAST biopsy takes place, but before any of those 
procedures are performed. The results from the laboratory safety tests must be
available and reviewed by the Investigator before the BC surgery takes place.
*Note: Should they coincide, it is acceptable for the Pre-surgery visit to take place on the day of a 
treatment period visit (if any). In such cases, assessments should be done according to the Pre-
surgery visit requirements.
6.4.4
BC Surgery/Pre-NAST biopsy
Surgery will be done according to site standards. In patients not receving NAST, BC tissue will be 
collected at time of surgery according to section 6.5.7. In patients receiving NAST, a breast tumor 
sample will be collected during the pre-NAST biopsy (refer to section 6.5.7) after completing 
darolutamide and before NAST start. As much as possible, sites should avoid scheduling BC 
surgery/pre-NAST biopsy on Mondays or on the day following a holiday, so that Pre-surgery visit may 
take place the day prior to BC surgery/pre-NAST biopsy according to section 6.4.3.
In the event that a sentinel lymph node biopsy (SLNB) is performed, periareolar injection is to be 
conducted.  The dye/colloid should not be injected into the tumor itself as this may alter the tissue 
and affect the molecular analyses to be performed on tumor tissue sample.  
6.4.5
End of Study Visit
EoS visit must be scheduled 30 days (+/- 3 days) after the last intake of darolutamide, even for 
patients who did not complete the minimum 14 days of protocol treatment.
The primary purpose of this visit is to follow-up any AEs/laboratory abnormality ongoing at the time 
of protocol treatment discontinuation and to assess any new AEs/abnormality that may have 
occurred since protocol treatment discontinuation. Symptom-directed physical examination, ECOG 
PS assessment and hematology/blood chemistry should be done at this visit. All AEs will be collected 
(even if due to neoadjuvant treatment, surgery or adjuvant treatment, regardless of the relationship 
to darolutamide), as well as relevant concomitant treatment according to rules in section 6.5.4.
EoS will be the last study visit with the exception of patients with protocol treatment-related 
AEs/SAEs that are ongoing at the time of the EoS visit. In these cases, monitoring of these events will 
continue as clinically indicated until (a) the events have resolved or (b) the events have reached a 
status which, in the Investigator’s opinion, is unlikely to resolve due to the nature of the condition 
and/or the patient’s underlying disease. Frequency of visits will be according to Investigator´s
judgment.
6.4.6
Unscheduled Visit Procedures
Unscheduled visits may be performed any time to assess or follow AEs, to perform any clinically-
indicated investigation, or at the request of the patient or Investigator.
6.5
Description of Assessments/Investigations
6.5.1
Demographics and Medical History
The Investigator will collect and report in the eCRF demographics and complete history of malignant 
and clinically-significant non-malignant diseases including known hypersensitivity reactions as well 
as clinically-significant symptoms.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 41
6.5.2
Physical Examination and Vital Signs
At screening and at the Pre-surgery visit, physical examinations will include a complete assessment 
of body systems (i.e., general appearance, head, eyes, ears, nose, mouth, skin, heart, lungs, lymph 
nodes, gastrointestinal, genitourinary, skeletal, and neurologic) per SoC at the study site or as 
clinically indicated by symptoms. As well, a complete examination of the breast and regional lymph 
nodes will be done. Weight, height and blood pressure will also be measured at screening, and 
therafter according to SoC.
During protocol treatment and EoS visits, a symptom-directed physical examination will be done.
6.5.3
ECOG Performance Status
Assessment of ECOG PS (Appendix 1) is required to assess patient´s functional status for study 
eligibility purposes and will be performed throughout the study according to the section 6.3.
6.5.4
Adverse Events and Concomitant Treatments Assessment

Adverse events assessment: For information on the assessment and collection of AEs refer 
to section 7 and to section 6.3.

Concomitant Treatments: Concomitant treatment includes any medication or therapeutic 
procedure (e.g. prescription drugs, over-the-counter drugs, herbal/homeopathic remedies, 
nutritional supplements, blood transfusions, etc.) used by a patient from 7 days prior to 
enrollment until EoS. The concomitant treatments to be collected and reported in the eCRF
are:
o
Any treatment used by the patient within 7 days prior to enrollment
o
After enrollment, only if: 

Medication is given to treat an AE

Medication is listed in sections 5.5.1 or 5.5.2
6.5.5
Laboratory Assessments
At screening:

Hematology: Hemoglobin, WBC, ANC and platelets

Blood chemistry: AST, ALT, total bilirubin and creatinine

Serum pregnancy test: within 7 days of enrollment, only in WoCBP
At the Pre-surgery and EoS visits:

Hematology: Hemoglobin, WBC, ANC and platelets

Blood chemistry: AST, ALT, total bilirubin and creatinine
6.5.6
Assessment of Efficacy
No efficacy assessments are planned in this study.  With the exception of the examination of breast 
and regional lymph nodes according to section 6.5.2, disease assessments will be conducted 
according to the SoC at the study site.  
6.5.7
Tumor Tissue Collection and Molecular Evaluation
All tumor samples will be submitted to the study Central Laboratory and will be stored for up to 20 
years, unless otherwise required per local regulations, Investigator, IRB/IEC and/or the patient.

Page 42
Full details on the analyses to be performed on the biologic samples and procedures for sample 
collection, labeling, storage and shipment/return of biological samples will be described in separate 
document(s) (e.g. Laboratory Manual, Samples Plan).
6.5.7.1 Breast Tumor Tissue Collection
Collection of the following samples is mandatory in the study:

Pre-treatment: A breast tumor sample must be collected at the time of the initial diagnosis 
(or in a subsequent procedure) either by core needle or incisional biopsy. Excisional biopsy 
will not be allowed. 
A minimum of 3 core biopsies using a 14-gauge needle (or the equivalent with an incisional 
biopsy) is recommended to perform the protocol-defined molecular analyses. Once the core 
biopsies have been removed, two of the cores (or equivalent amount of tumor) must be 
immediately snap-frozen using the procedure outlined in the study laboratory manual, then 
stored in liquid nitrogen or at -70 to -80 degrees Celsius at the site. The third sample should 
be prepared in paraffin according to site’s practice. In cases it is not possible to provide 
enough material, collection of 2 cores (or equivalent amount with incisional biopsy) will be 
acceptable: one core will be snap-frozen and the other one will be prepared in paraffin.
In patients with multifocal or multicentric tumors, efforts will be made to obtain samples 
from each discrete lesion.
For patients who already had the confirmatory biopsy prior to registration, there is no need 
to repeat it provided that their diagnostic biopsy has been done according to the protocol 
requirements (in terms of number of cores/tissue, fresh frozen collection, etc.).

BC surgery/Pre-NAST biopsy: An amount of BC tissue equivalent to two cores (or 2 cores of 
tissue) must be collected at the time of the patient’s surgery (if no NAST indicated) or at 
time of the pre-NAST biopsy (if NAST is indicated). The pre-NAST biopsy should be done 
before NAST start. Half of the tissue will be prepared as fresh-frozen, the other half in 
paraffin.  
6.5.7.2 Molecular Evaluation
The primary endpoint of the study is to explore and define the molecular alterations that may occur 
following darolutamide administration through comparisons of BC tissue before and after short-term 
exposure to darolutamide.
At least, the following markers will be assessed on the collected samples. In all experiments, 
appropriate positive and negative controls will be included.

AR

ER

PgR

HER2 

ki67

Cytokeratins 5 and 6
Tissue microarrays will be developed from all tumor specimens. Other in situ assays for activated 
downstream signaling molecules will be performed using tissue sections and/or tissue microarrays. 
Promising candidate genes obtained from the microarray analysis will be validated using the frozen

tissue arrays generated above and using appropriate probes (i.e. antibodies, if available, or nucleic 
acid probes).
Additional assays in example but not limited to Reverse Phase Protein Analysis (RPPA), sequenciation 
of the RNA, immunohistochemistry (IHC) etc. may be performed based on the molecular analysis 
finding and/or in the future as new technology and data become available.
6.5.8
Other Procedures/Assessments
In addition to the protocol-required assessments, the Investigator may perform any clinically 
indicated test and procedure according to SoC (e.g. coagulation test prior to surgery, etc.) although 
these will not be collected in the eCRF.
7. SAFETY MONITORING
7.1
Definitions
7.1.1
Period of Observation
At each visit and any contact during the study and follow-up period, the Investigator or designee will 
inquire about the occurrence of AEs (and corresponding medications administered) and will 
document them in the eCRF.
For the purposes of this study, the period of observation for SAEs and AEs extends from the time the 
patient signs the PICF until the EOS, except for patients that are experiencing AEs or SAEs related to 
darolutamide ongoing at the time of EoS visit. In such cases, these events will be monitored beyond 
the EoS visit as clinically indicated until (a) the events have resolved or (b) the events have reached a 
status which, in the Investigator’s opinion, is unlikely to resolve due to the nature of the condition 
and/or the patient’s underlying disease. 
The Investigator or designee will report the AEs/SAEs in the eCRF (and, if applicable, to TRIO Safety 
Department) when required as per the table below:

7.1.2
Adverse Event
An AE is defined as any untoward medical occurrence, including an exacerbation of a pre-existing
condition, in a patient in a clinical investigation who received a pharmaceutical product. The event 
does not necessarily have to have a causal relationship with this treatment.
Worsening of pre-existing conditions: any pre-existing condition present at baseline, which remains 
unchanged during the trial, does not need to be recorded as an AE.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 44
Any worsening of any pre-existing baseline condition should be reported as an AE in the eCRF. 
Examples of worsening of a preexisting condition that should be recorded as an AE are given below:   

Worsening of condition meets the criteria for an AE or SAE

Action is taken with the investigational drug (e.g. dose is reduced or treatment is 
discontinued)

Treatment is required (concomitant medication is added or changed)

The Investigator believes a patient has shown a clear deterioration from baseline symptoms
Expected fluctuations or expected deterioration of the BC (symptoms of disease progression) should
not be recorded as an AE.
Changes in vital signs, physical examination and laboratory test results: these will only be recorded
as an AE in the eCRF if they are judged clinically relevant by the Investigator or led to protocol 
treatment modifications (dose delay or dose reduction).
Surgical procedures: these are not AEs per se; they are therapeutic measures for conditions that 
require surgery. The condition for which the surgery is required may be an AE. Planned surgical 
measures permitted by the clinical study protocol and the condition(s) leading to these measures are 
not AEs.
Worsening of a sign or symptom of the condition under treatment: these situations (i.e. BC) should 
not be recorded as AEs.
7.1.3
Serious Adverse Events
A SAE is one that at any dose:

Results in death

Is life-threatening1

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability or incapacity2

Is a congenital anomaly or birth defect

Is an important medical event3
1 “Life-threatening” means that the patient was at immediate risk of death at the time of the SAE; it does not 
refer to a SAE that hypothetically might have caused death if it were more severe.
2 “Persistent or significant disability or incapacity” means that there is a substantial disruption of a person’s 
ability to carry out normal life functions.
3 Medical and scientific judgment should be exercised in deciding whether expedited reporting is appropriate 
in situations where none of the outcomes listed above occurred. Important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the patient or may 
require intervention to prevent one of the other outcomes listed in the definition above should also usually 
be considered serious. Examples of such events include allergic bronchospasm requiring intensive treatment 
in an emergency room or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, the development of drug dependency or drug abuse, etc.
7.1.3.1 Disease-related Events
An event that is part of the natural course of the disease under study (i.e. breast cancer) does not
need to be reported as an SAE.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 45
However, if the Investigator considers that there was a causal relationship between treatment with
investigational product or protocol design/procedures and a disease progression, then this must be
reported as an SAE. Any new primary cancer must be reported as an SAE.
7.1.3.2 Planned or Administrative Hospitalization
Patients may be hospitalized for administrative or social reasons during the trial (e.g. long distance
from home to site, etc). These and other hospitalizations planned up to enrollment do not need to
be reported as an SAE but should be properly documented in the source data.
7.1.4
Unexpected Adverse Event
The Darolutamide IB provides an overview of the AEs reported across each clinical trial. 
Any SAE assessed as related to darolutamide but not presented in the IB section 8.6 Undesirable 
effects will be documented by TRIO as a suspected unexpected serious adverse reaction (SUSAR) and 
will be submitted according to applicable local regulations.
7.2
Performing Adverse Event Assessment
7.2.1
Collection of Adverse Event Information
The following information will be collected in the eCRF: Description of event (a single medical 
condition and not a collection of signs/symptoms), start/stop dates, worst grade experienced 
(severity/intensity), seriousness, action taken on protocol treatment and relationship to protocol
treatment.
Intensity of AE: The intensity of AEs will be classified and recorded according to the NCI CTCAE
version 4.03 in the eCRF, or according to the grading defined in section 5.4.1 if the AE is not 
specifically listed in NCI CTCAE.
All adverse clinical experiences, whether observed by the Investigator or reported by the patient, 
must be recorded, with details about the duration and intensity of each episode, the action taken 
with respect to the test drug (refer to section 5.4.2 for recommendations on dose modifications), 
and the patient’s outcome.  The Investigator must evaluate each adverse experience for its 
relationship to the test drug and for its seriousness.
The Investigator must appraise all abnormal laboratory results for their clinical significance. If any 
abnormal laboratory result is considered clinically significant, the Investigator must provide details 
about the action taken with respect to the protocol treatments and about the patient’s outcome.
7.2.2
Assessment of Causality
Medical judgment should be used to determine the relationship, considering all relevant factors, 
including pattern of reaction, temporal relationship, de-challenge or re-challenge, confounding 
factors such as concomitant medication, concomitant diseases and relevant history. Assessment of 
causal relationship must be recorded for each adverse event.
Relationship to study drugs will be reported as either “Yes” or “No”.

Yes: there is a reasonable causal relationship between the IMP administered and the AE.

No: there is no reasonable causal relationship between the IMP administered and the AE.

Management of Specific Cases
7.4.1
Medication Errors
In the event of a medication error, the patient should be observed closely for signs of toxicity. 
Medication errors include the accidental or intentional use of darolutamide in a daily dose greater 
than the protocol-specified daily dose. Appropriate supportive treatment should be provided if 
clinically indicated. In case of toxicity derived from the medication error, dose modification 
recommendations from section 5.4.2 should be followed. 
The highest darolutamide dose administered in clinical trials is 1,800 mg daily, with no maximum 
tolerated dose achieved and no dose-limiting toxicity experienced by patients. 
If an AE is associated with (“results from”) a medication error, the corresponding AE should be 
reported as SAE, even if no other seriousness criteria are met.
In cases of a medication error without any associated AE, the medication error should be reported as 
a non-serious AE, using terminology like “accidental or intentional overdose without adverse effect”, 
“medication error without adverse effect” or similar.
7.4.2
Pregnancy
Should a pregnancy occur, the Investigator must discontinue treatment immediately, capture any 
drug exposure during pregnancy, report the pregnancy through the Pregnancy Reporting Form and 
follow the pregnancy until outcome is known. Information related to outcome of the pregnancy, 
delivery, postpartum recovery and the clinical condition of the offspring during the neonatal 
period must also be collected.
Pregnancy is not automatically considered as a SAE, however, it must be reported following SAE 
timeline as detailed in section 7.3.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL

A SAE report must be forwarded to the TRIO if the outcome of the pregnancy results in an 
abortion/miscarriage or the occurrence of any other SAE(s).
7.5
Reporting to Ethics Committees, Regulatory Authorities and other 
Investigators
Prompt notification of SAEs by the Investigator to TRIO is essential so that legal obligations and 
ethical responsibilities towards the safety of patients are met.
TRIO will comply with local regulatory requirements relating to safety reporting to the regulatory 
authorities, IRB/IEC and Investigators.
TRIO will report SAEs and related safety information to the FDA as per the definitions and 
reccomendations in 21 CFR 312 and per the FDA guidance for Industry and Investigators (available at
http://www.fda.gov/downloads/Drugs/.../Guidances/UCM227351.pdf).
Investigator safety reports are prepared for SUSARs according to local regulatory requirements and 
are forwarded to Investigators as necessary.
An Investigator who receives an Investigator safety report describing a SAE(s) or other specific safety 
information (e.g., summary or listing of SAEs) from TRIO will file it with the IB and will notify the 
IRB/IEC, if appropriate according to local requirements.
8. STATISTICAL CONSIDERATIONS
8.1
Study Populations

Intention-to-treat (ITT) Population: The ITT population includes all patients who are enrolled 
in the study regardless of whether they have been treated or not.

Safety Population: The Safety population includes all patients who have taken at least one 
tablet of darolutamide.

Evaluable population: Includes all patients who satisfied all criteria in section 8.5.
8.2
Demographics and Baseline Characteristics
Demographics and baseline characteristics data will be listed and summarized by each BC subtype 
using the ITT population.
8.3
Protocol Treatment
Duration of treatment, duration of exposure, cumulative dose and relative dose intensity will be
summarized by each BC subtype using the Safety population. The patients with dose modifications 
will also be presented, along with reasons for the dose change.
8.4
Safety Evaluation
The assessment of safety will be made on the Safety population and will be based mainly on the 
frequency of AEs. The latest version of the Medical Dictionary for Regulatory Activities (MedDRA) 
will be used to code all AEs to a preferred term and system organ class. AEs will be graded using the
NCI CTCAE v4.03 or according to the applicable grading if the AE is not specifically listed in NCI 
CTCAE. Patient’s incidence of AEs will be tabulated by system organ class, preferred term and 
toxicity grade for each BC subtype. AEs leading to death or drug discontinuation, drug related and
SAEs will also be summarized.
Detailed listings for all AEs will also be provided.

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 48
Laboratory parameters: these will be summarized at baseline, along visits and at the EoS visit by
each BC subtype, graded according to the NCI CTCAE v4.03. Tables of shifts in toxicity will also be
provided.
Other Safety Data: ECOG will be summarized at baseline, along visits and at the EoS visit by BC 
subtype. Tables of shifts in toxicity will also be provided when applicable.
8.5
Sample Size 
The primary objective of this trial is to evaluate molecular alterations occurring in BC tissue following 
short-term darolutamide administration. 
Up to 60 patients (minimum of 8 but up to 20 patients in each BC subtype: triple-negative, 
HR+/HER2 negative, HER2 positive) will be required for the performance of the molecular studies 
and possible hypothesis generation. 
A patient will be considered evaluable if the following criteria are met:

Minimum duration of treatment with darolutamide is of 14 days, with a minimum of 10 
consecutive days of treatment prior to the definitive BC surgery/pre-NAST biopsy. 

Mandatory tumor tissue is collected at screening and at BC surgery/pre-NAST biopsy 
according to the protocol and submitted to the central laboratory.

Adequacy for molecular assessment of the tumor tissue collected before and after the 
protocol treatment initiation. The adequacy will be evaluated by the central laboratory.
Assessment of patient evaluability, safety and distribution of patients with respect to hormone 
receptor status and HER2 status will be performed by the SSC at given time points depending on the 
recruitment, for example once 20, around 35 and once all patients have been enrolled and 
undergone the EoS per protocol. This will allow SSC to ascertain that the appropriate number of 
evaluable patients is being accrued, that more or less patients may be required, or in the extreme 
case, that accrual should close if the patient evaluability rate is very low and/or safety concerns 
arise.
The SSC will define the evaluability of patients that discontinue treatment more than 3 days before 
BC surgery/pre-NAST biopsy; molecular analyses may be taken into consideration for the decision 
about the evaluability of such patients. 
8.6
Molecular Analyses
The molecular analyses will be performed on the evaluable population. Descriptive statistics will be 
used to compare the pre-and post molecular findings.
A correlation analysis between the molecular alterations from the baseline tumor samples and the 
sample collected following administration of darolutamide, during the definitive BC surgery/pre-
NAST biopsy will be conducted.
9. ADMINISTRATIVE, ETHICAL AND REGULATORY STANDARDS
9.1
Steering Committee
The SSC of the trial will be composed of the study Chair(s) and representatives from TRIO. The SSC 
will include also a number of study principal Investigators. Other members may be added after 
consultation with the SSC members. The SSC will be constituted prior to the enrollment of the first 
patient. 

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 49
The SSC will have the sole responsibility for the scientific conduct and integrity of the trial. 
Responsibilities include development and approval of the protocol document, monitoring of accrual, 
compliance and safety during the conduct of the trial. The SSC will be solely responsible for the 
analysis, interpretation and public disclosure of the results of the trial in accordance with the 
statistical plan. The SSC should endeavor to ensure that the study is conducted at all times to the 
standards set out in Guidelines for Good Clinical Practice (GCP). In all of the deliberations of the SSC, 
the rights, safety and well being of the study participants are the most important considerations.
9.2
Ethical Conduct of the Study
This clinical study was designed and shall be implemented and reported in accordance with the
clinical trial protocol, the ICH Harmonized Tripartite Guidelines for Good Clinical Practice, applicable 
local regulations (including European Directives 2001/20/EC and 2005/28/EC and the US Code of 
Federal Regulations Title 21), the Council for International Organizations of Medical Sciences 
(CIOMS), and the ethical principles laid down in the Declaration of Helsinki. This study will be 
conducted under ethical, scientific and medical standards that protect the rights and welfare of 
participants. 
9.3
Institutional Review Board/Independent Ethics Committee (IRB/IEC) 
Each participating institution must provide for the review and approval of this protocol and the 
associated informed consent documents and recruitment material by an appropriate IEC or IRB. The 
IEC/IRB decision concerning the conduct of the study will be made in writing and kept with the 
Investigator study file. A copy of this decision will also be provided to TRIO.
Particular attention is drawn to the Food and Drug Administration (FDA’s requirements for IRBs 
under 21 CFR Part 56). By signing the "Statement of Investigator" form (Form FDA 1572), the 
Investigator provides TRIO with the necessary assurance that an IRB is responsible for the 
initial/continuing review and subsequent approval of the proposed clinical study in accordance with 
these regulations when applicable.
The Investigator will agree to make required progress reports to the IEC/IRB, as well as report any 
SAEs, life-threatening problems or deaths if applicable per local regulations. The IEC/IRB will be 
informed of SAEs in other clinical studies conducted with the study drug by the Investigator or the
Sponsor according to the local regulations. The IEC/IRB must be informed by the Investigator of the 
termination of the study.
9.4
Compliance with the Protocol and Protocol Amendments
Investigators ascertain they will apply due diligence to avoid protocol deviations. Under no 
circumstances should the Investigator contact TRIO or its agents monitoring the trial, if any, to 
request approval of a protocol deviation, as no such authorized deviations are permitted. 
If the Investigator feels a protocol deviation would improve the conduct of the study this must be 
considered a protocol amendment, and unless such an amendment is agreed upon by TRIO and 
approved by the IRB/IEC it cannot be implemented. All significant protocol deviations will be 
recorded and reported in the Clinical Study Report (CSR).
Any modifications to the protocol which may impact on the conduct of the study, potential benefit 
of the patient or may affect patient safety, including changes of study objectives, study design, 
patient population, sample sizes, study procedures, or significant administrative aspects will require 
a formal amendment to the protocol. Such amendment will be agreed upon by TRIO, and approved 
by the Ethics Committee/IRB and Health Authorities where required, prior to implementation. Only 
amendments that are required to eliminate an immediate hazard to patients for patient safety can

TRIO030 Protocol 
Version 3.0 (16 February 2018)
CONFIDENTIAL
Page 50
be implemented prior to IRB/IEC approval. Notwithstanding the need for approval of formal protocol 
amendments, the Investigator is expected to take any immediate action required for the safety of 
any patient included in this study, even if this action represents a deviation from the protocol. In 
such cases, TRIO should be notified of this action and the IRB/IEC at the study site should be 
informed.
9.5
Monitoring, Auditing and Inspecting
TRIO or its representatives must be allowed to visit all study site locations periodically to assess the 
data, quality, and study integrity. On site, they will notably review study records and directly 
compare them with source documents, review regulatory documents, discuss the conduct of the 
study with the Investigator, verify study drug accountability, and verify that the facilities remain 
acceptable.
9.6
Recording, Processing and Retention of Data
The Investigator is responsible for the preparation and maintenance of adequate case histories 
designed to record all observations and other relevant data. All patient data reported on the eCRF
must be derived from source documents and as such be consistent with the source documents, or 
the discrepancies must be explained.
Data will be entered and collected via an electronic data capture system using eCRFs. RDC is a 
validated system designed for entry of data in a way that is attributable, secure, and accurate, in 
compliance with U.S. FDA regulations for electronic records (21 CFR Part 11). Study site staff will 
receive training and have access to a manual for appropriate eCRF completion. All eCRFs should be 
completed by designated, trained site staff. eCRFs should be reviewed and electronically signed and 
dated by the Investigator or authorized designee. Only identified and trained users may view the 
data as their actions become part of the audit trial.
While study sites will be responsible for data entry, TRIO will be responsible for data management of 
this study, including quality checks.
The eCRF must be completed within 7 calendar days of data availability. All requested information 
must be entered on the eCRF. If an item is not available or is not applicable, it must be documented 
as such. The completed eCRF must be reviewed and approved by the Investigator or authorized 
designee. In the event of discrepant data, TRIO will request data clarification from the sites. The sites 
will resolve the discrepancy electronically in the RDC system. eCRF and data clarification 
documentation will be maintained in the RDC system’s audit trail.
At the end of the study, the Investigator will receive patient data, for their site, in a readable format 
on CD, DVD, or other similar storage format that must be kept with the study records. 
Acknowledgement of receipt of the storage disc or similar is required.
The Investigator should retain the study documentation according to ICH-GCP, local regulations or as 
indicated in the contractual agreement whichever is longer.
9.7
Data Protection
Patient confidentiality is strictly held in trust by the participating Investigators, their staff, TRIO or 
affiliates. This confidentiality is extended to cover testing of biological samples and genetic tests in 
addition to the clinical information relating to participating patients.
Patient and Investigator personal data which may be included in the study database shall be treated 
in compliance with all applicable laws and regulations.
