Brief summary:
This study was a phase III, multicenter, triple-blind, equivalency clinical trial to determine the therapeutic efficacy and safety between Pertuzumab® (CinnaGen Co.) compared to originator pertuzumab in HER2-positive early breast cancer patients.

Patients were stratified dynamically for random assignment to treatment with either Pertuzumab® (CinnaGen Co.) or originator pertuzumab, and received neoadjuvant TCHP regimen every 3- weeks.

Detailed description:
This study was a phase III, multicenter, triple-blind , equivalency clinical trial to determine the therapeutic efficacy and safety between Pertuzumab® (CinnaGen Co.) compared to originator pertuzumab in HER2-positive early breast cancer patients.

Patients stratified dynamically according to two factors: type of breast cancer (inflammatory, locally and operable) and estrogen/ progesterone receptor (ER/PR) (positive or negative) with 1:1 allocation ratio.

Study drugs were administered intravenously on a 3-weekly schedule and were given consecutively on the same day in the following sequence: trastuzumab, followed by pertuzumab, carboplatin, and docetaxel (TCHP regimen).

The primary endpoint was breast pCR (bpCR). Secondary efficacy endpoints included total pCR (tpCR); objective response rate (ORR) and rate of breast-conserving surgery (BCS) for patients for whom mastectomy was planned before treatment (T2-3).

During this study, adverse events (AEs) were monitored continuously. As an adverse event of special interest (AESI), left ventricular ejection fraction (LVEF) decreased was monitored and assessed by echocardiography throughout the study. Immunogenicity was also assessed.

Arms: arm 1: Study drugs are administered intravenously on a 3-weekly schedule and given consecutively on the same day in the following sequence: trastuzumab, followed by pertuzumab, carboplatin, and docetaxel. Trastuzumab is given at an initial dose of 8 mg/kg, followed by 6 mg/kg; pertuzumab® (CinnaGen Co.) is given at an initial dose of 840 mg, followed by 420 mg. Carboplatin is administered at a dose of AUC6 (area under the plasma concentration-time curve) and docetaxel is given at 75 mg/m2. arm 2: Study drugs are administered intravenously on a 3-weekly schedule and given consecutively on the same day in the following sequence: trastuzumab, followed by pertuzumab, carboplatin, and docetaxel. Trastuzumab is given at an initial dose of 8 mg/kg, followed by 6 mg/kg; Perjeta® is given at an initial dose of 840 mg, followed by 420 mg. Carboplatin is administered at a dose of AUC6 (area under the plasma concentration-time curve) and docetaxel is given at 75 mg/m2.
Interventions: intervention 1: Trastuzumab intervention 2: Pertuzumab intervention 3: Carboplatin intervention 4: Docetaxel
Intervention descriptions: intervention 1: An initial dose of 8 mg/kg, followed by 6 mg/kg every 3-weeks intervention 2: An initial dose of 840 mg, followed by 420 mg every 3-weeks intervention 3: A dose of AUC6 (area under the plasma concentration-time curve) every 3-weeks intervention 4: 75 mg/m2 every 3-weeks

Introduction
Background and Rationals for the Study
Breast cancer
Breast cancer is a disease in which certain cells in the breast become abnormal and divide
uncontrollably to form a tumor. Breast cancer is the second most commonly diagnosed cancer
in women. About one in eight women in the United States will develop invasive breast cancer
in her lifetime. Researchers estimate that more than 230,000 new cases of invasive breast
cancer will be diagnosed in U.S. women in 2015 (1).
Some genes and the proteins can determine how a breast cancer behaves and how it might
respond to a specific treatment. Human epidermal growth factor receptor 2 (HER2) is one of
the such genes that can play a role in the development of breast cancer (2). The amplification
of the HER2 gene leads to overexpression of the receptor, which is linked to the development
of many types of human cancers including breast, ovarian and those of the gastrointestinal tract
(3).
Human epidermal growth factor receptor 2 (HER2) is overexpressed in 25% to 30% of breast
cancers, suggesting a role for overexpression in tumorigenesis. This overexpression is most
commonly the result of gene amplification. Several lines of evidence support the role of HER2
overexpression in the pathogenesis and poor clinical outcome of human tumors. A number of
these studies have shown that breast cancers that overexpress HER2 have a more aggressive
course and higher relapse and mortality rates (4).
Knowledge of HER2 status is a prerequisite when considering a patient's eligibility for
Herceptin (trastuzumab) therapy. Accurate assessment of HER2 status is essential to ensure
that all patients who may benefit from Herceptin are correctly identified. There are several
assays available to determine HER2 status: the most common in routine clinical practice are
immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) (5).
Treatment
According to the studies, the most common and prevalent type of breast cancer would be breast
cancers with positive esterogen/progestrone receptors. Endocrine treatment for breast cancers
with positive non metastatic hormonal receptor includes tamoxifen and aromatase inhibitors
(anastrazole, letrozole and exemestane). (6, 7)

Two target therapy method for breast cancer treatment include HER2 pathway and
angiogenesis pathway. Studies shows that although prescription of Bevacizumab with
angiogenesis inhibitor mechanism pathway can increase clinical complete response in patients
with breast cancer, but still hasn’t been approved the usefulness of the drug in increasing
survival (8-10).
Several murine monoclonal antibodies against the extracellular domain of the HER2 protein
were found to inhibit the proliferation of human cancer cells that overexpressed HER2, both in
vitro and in vivo (11). In 1980, one monoclonal antibody was made against HER2 and named
Trastuzumab. In 1998, trastuzumab (Herceptin®; Genentech Inc. South San Francisco, CA) as
a humanized monoclonal antibody directed against the extracellular domain of HER2 was
approved as adjuvant treatment for breast cancer and treatment of metastatic breast cancer (12).
In a study which has been done by Buzdar et al, the efficacy level of Trastuzumab was assessed
along with chemotherapy regimen. Clinical complete response in Trastuzumab arm was 65.2%
comparing to 26.3% in non-Trastuzumab chemotherapy regimen arm. The 3 years’ survival
rate was 100% in Trastuzumab arm comparing to 85.3% in non-Trastuzumab chemotherapy
regimen arm (4).
In a meta-analysis study, which was done in 2012 and included 12000 patients, efficacy of
Trastuzumab chemotherapy regimen was assessed by non-Trastuzumab chemotherapy regimen
and confirmed prescription of Trastuzumab increases overall survival in 12 months. Although
prescription of Trastuzumab less than 6 months, showed level of increment of overall survival
(13).
Pertuzumab
Recently, new treatments with HER2 targeting have been developed and Pertuzumab as a
monoclonal humanized antibody which connect to different epitope of HER2 external receptor
(subgroup II) is one of them (14). Pertuzumab prevents HER2 dimerization with other HER
receptors, especially HER3 (15).
Like Trastuzumab, Pertuzumab also induce antibody-dependent cellular cytotoxicity (ADCC)
pathway. Since Pertuzumab and Trastuzumab attach to different epitopes of HER2 and have
complementary effect, concurrent prescription of these two drugs causes more inhibition in
HER2 signaling and anti tumor activity comparing to single use of them (16, 17). Efficacy of

Clinical Trial Protocol
CinnaGen Co.
Trastuzumab-Pertuzumab regimen in patients with HER2+ breast cancer patients has been
shown in phase II trials (18-20).
In 2012, phase III clinical trial of Trastuzumab and Pertuzumab (CLEOPATRA) has been
assessed safety and efficacy of Docetaxel and Trastuzumab plus Pertuzumab comparing to
placebo as fist line treatment in HER2+ metastatic breast cancer patients. In this study, 808
patients in 204 centers were treated and the median of Progressive Free Survival (PFS) in
Pertuzumab arm showed 6.1 months’ increment compared to placebo arm. Furthermore, in this
study, the ratio of treatment reponse in Pertuzumab arm showed 10.8% improvement compared
to the placebo arm and reached to 80.2% (21).
Study on assessing safety and efficacy of neoadjuvant Pertuzumab and Trastuzumab in women
with locally advanced breast cancer or HER2+ inflammation (NeoSphere study) caused
accelerated approval in using this medication in neoadjuvant treatment. This phase II study
conducted with 4 arms to assess effect of Docetaxel, Trastuzumab and Pertuzumab in different
regimen. (19).
In 2013, another study with the aim of assessing the heart complications in neoadjuvant therapy
combination of Trastuzumab and Pertuzumab for HER2+ breast cancer patients were done and
checked the chemotherapy regimen with or without Antracycline. In this study, 225 patients
were assessed and according to the results, heart complications did not show statistical
significance difference between 3 treatment arm and the most treatment response (66.2%) was
related to Docetaxel, Trastuzumab and Pertuzumab and carboplatin (22).
Pharmacological propertis
Pertuzumab is a recombinant humanised monoclonal antibody that specifically targets the
extracellular dimerization domain (subdomain II) of the human epidermal growth factor
receptor 2 protein (HER2), and thereby, blocks ligand-dependent heterodimerisation of HER2
with other HER family members, including EGFR, HER3 and HER4. As a result, pertuzumab
inhibits ligand-initiated intracellular signalling through two major signal pathways, mitogen-
activated protein (MAP) kinase and phosphoinositide 3-kinase (PI3K). Inhibition of these
signalling pathways can result in cell growth arrest and apoptosis, respectively. In addition,
pertuzumab mediates antibody-dependent cell-mediated cytotoxicity (ADCC).

While pertuzumab alone inhibited the proliferation of human tumour cells, the combination of
pertuzumab and trastuzumab significantly augmented antitumour activity in HER2-
overexpressing xenograft models (21).

Rationale for the Study
Different studies showed enhanced anti tumor activity of Pertuzumab along with trastuzumab
in breast cancer patients. Due to high price of this antibody and due to not availability of this
drug in Iran’s drug list, the CinnaGen Co.decided to produce this drug. This study has been
designed as a neoadjuvant treatment in patients with HER2+ breast cancer and patients
randomized in 2 gropus receiving Pertuzumab (manufactured by CinnaGen Co.) and Perjeta
(Refrence drug, manufactured by Genentech). Patients in this study will receive Docetaxel,
Trastuzumab and Pertuzumab and carboplatin regimen every 3 weeks for 6 periods in the form
of IV.
The most important objectives of this study would be efficacy and safety comparison of
Pertuzumab (manufactured by CinnaGen Co.) and Perjeta manufactured by Genentech in
neoadjuvant setting for HER2+ breast cancer patients.

Prevention of nausea
Recommened to be premedicated with a serotonin antagonist (8-16 mg Ondansetron with 1-2
mg Granisetron), Neurokinin inhibitor (125 mg Aperpitant) and Dexametasone (8mg) in the
day of chemotherapy.
Diarrhea
It is recommened to use Loperamide (4mg and then 2 mg every 4 hours up to 16 mg daily) till
12 hours after cessation of diarrhea.
Prevention of infusion related recations
Dexamethasone 8 mg PO bid for 3 days, starting one day prior to each Docetaxel
administration. Pre treatment usually is not used for Pertuzumab and carboplatin, however in
the case of flu-like side effects within 24 hours after Trastuzumab administration; it is
recommened to use Acetaminophen or NSAID.
Dose Adjust in Hepatic or Renal impairment
Docetaxel should not be administered to patients with bilirubin more than ULN or with
transaminase more than 1.5 times ULN and alkaline phosphatase more than 2.5 times ULN.
Each dose of Carboplatin should be caculated according to kidney activity and based on the
Calvert formula.

Sample Size
Using an equivalence margin of 0.2, a sample size of 96 subjects in each one of both
Pertuzumab (CinnaGen Co.) and Perjeta® (Genentech Co.) groups achieves 80% power to
detect bioequivalence for the difference between groups. The actual difference is considered
zero. The PCR efficacy for Perjeta® group is 0.66 (22, 24, 25). Two-way independent T-test
with 5% significance level will be used to analyze the results. Considering 10% dropout, final
sample size is considered 107 in each group.
Recruitment
This study has two arms and 214 patients will be enrolled (107 patients in each arm)
1) Group 1: Patients who receive Pertuzumab (Manufactured by CinnaGen Co.) every 3
weeks with Trastuzumab, Carboplatin, Docetaxel
2) Group 2: Patients who receive Perjeta® (Manufactured by Genentech) every 3 weeks with
Trastuzumab, Carboplatin, Docetaxel
Randomization
Patients will be dynamically randomized to different groups during the study using
Minimization method (with a 90% random component). The two main variables on which the
balance is performed will be as follows:
1- ER/PR: ER/PR+, ER/PR-
2- Type of breast cancer: operable, locally advanced, inflammatory
At the beginning of the study, each patient will receive a unique code in order to be recognized
during the study. The assigned code consists of 4 letters (corresponding to the first two letters
of the first name and the first two letters of the surname), three digits (center code), the first
three letters of the generic drug name (which is PER-) and 3 digits (corresponding to
randomization code). For example: ABCD001PER-001.
Each Pertuzumab package which will be used for a patient's treatment during the study and
will be recognized by a unique 3-digit code similar to the randomization code (this number
includes two English letters and a number which will be unique for each subjetcs).
Blinding
48


Both Pertuzumab drugs in this study are not identifiable by patients and treatment group. Since
the administration route of this drug is IV infusion, patients’ blinding in medication groups
would be possible. Furthermore, persons who are doing the data analysis are not aware of
patients’ grouping.
Patients’ groups and type of their medications will not disclose to investigators and will be in
the stamped pocket and will be provided to investigator of each site. Persons who are doing
analysis are not aware of grouping.
Data Collection Methods
Data collection will be electronic-based and the data will be recorded in eCRF. Adequate
attention will be given to collect accurate and valid data. Investigators are responsible for
completing the eCRF in study centers. The sites will be equipped with personal computers or
tablets. Only the investigator or the person assigned by the investigator will have access to the
database for data entry.
Data Management
The principal investigator, investigators, and other personnel assigned by the investigators will
be responsible for eCRF data entry. Each investigator will be given a specific username and
password. The PI and investigators must not disclose the data obtained from the study. All of
the Investigators are responsible for keeping the study data safe. Sending and receiving the
patients' information must be done considering safety and security procedures. Trial CRO is
responsible for planning a monitoring which will be conducted by qualified personnel in order
to check the eCRF for discrepancies with the patients’ source documents. The monitors or
auditors are not able to change eCRF data. However, they can make queries for blatant mistakes
in data entry and the investigator is responsible for rectifying such mistakes or answering to
the queries. The history of modification in eCRF data will be recorded meticulously and can
be observed by the monitors or auditors.
Data Monitoring
The objectives of the data quality control are:

To ensure the existence of the patients and the respect of ethics (including signed
patient informed consent)
49



To detect the issues (including systematic errors) as early as possible for appropriate
measures to be taken

To ensure the validity of the data
To meet these objectives, quality control should be applied via the following activities:
The schedule of site quality control evaluation, performed by the monitoring team must be
explained to the investigators at the time of site initiation visit and agreed upon. QC will be
performed in study sites by the monitoring team who are in charge of planning for action plans
to improve study site quality.
QC of the study site will be carried out during two main monitoring visits (30% and 70% of
study completion) and several periodic monitoring visits throughout the study.
In every monitoring visit the following items will be evaluated according to a pre-prepared
check list and the quality control report will be completed.

eCRF forms will be assessed in terms of completeness, the quality of data entry and
accordance with source data.

Informed consent forms signed by the patient and the physician for all the patients
who have gone through the screening visit

Evaluation of key variables regarding the wrong and missing data
Statistical Analysis
Statistical analysis of data will be conducted by the study statistical consultant. Additionally,
the available data will be evaluated separately by the Trial CRO representative and the results
will be compared. The final analysis will be assessed by the Steering Committee prior to
submission to the Food and Drug Administration.
It should also be noted that in order to prevent any bias in the analysis, all the results will be
reviewed in joint meetings with Trial CRO on behalf of Dr. Hamed Hosseini and approved by
the Trial CRO team.
50


Statistical Methods
The primary endpoints will be analysed for Per-protocol population. Moreover, primary
endpoints and secondary endpoints in intention-to-treat/FAS population will be assessed and
for comparison of primary endpoints, sensisitivity anlysis will be applied.
All adverse events analysis was conducted based on the Saftey population
1. Per-protocol population: All randomized patients who treated with trial drugs and does not
have a major violation with protocol.
2. Intention- to – treat population: All randomized patients who were allocated to treatment
groups and received at least one dose of study drug. The patients were analyzed based on their
treatment group which was randomized.
3. Safety population: All patients who randomly received at least one dose of the drugs. The
patients were analyzed based on the randomized received drugs.
Missing Data
Graphical methods (standard tables and figures) will be used to recognize potential outliers.
Then, the analyses will be conducted including/excluding outliers. Finally, the results of the
two model will be compared considering the effect of outliers.
Both pre-protocol and FAS/ITT populations (with and without imputation) will be reported for
the primary endpoint analysis. In case there is no final answer, the worst-case scenario “NO
PCR” will be applied. Then, the results will be comaprd and if there was any significant
differences, the reason will be evaluated.
Covariate Adjustment
Since the randomization method in this study is Minimization, the results of patients who will
be randomly assigned to one of the treatment groups at the beginning of the study will be
compared with that of other patients who will assigned to their treatment group using
Minimization method during the study.
Patient Characteristics and Baseline Comparisons
Descriptive statistics of thew data will be presented in the study. For categorical variables,
number and percentage of patients in each category, and for continuous variables, mean,
standard deviation, and quartiles will be calculated.
51


Primary Endpoint Analysis
Primary endpoint (pCR) analysis, will be conducted using a two-sided 95% confidence interval
with equivalence margin of 0.2. Equivalence of Pertuzumab (CinnaGen Co.) and Perjeta® will
be concluded if the resulted 95% confidence interval for the difference will be within the
predetermined range (-0.2, 0.2)
Secondary Endpoint Analysis
The clinical response rate and tpCR in both treatment groups will be calculated and compared
using the ratio test.
The conserving surgery rate in both treatment groups will be calculated and their comparison
will be done using the ratio test.
Safety Endpoint Analysis
All adverse events data will be descriptively analyzed.
Adverse events: The number and percentage of adverse events caused by treatment will be
classified by organ system class and preferred term will be applied. Laboratory data of
hematology and biochemistry will be graphically displayed to show the trend of changes
between treatment groups.
Frequency of abnormal parameters will be reported in each visit. Furthermore, clinical
significant items will be determined in the study. Change in vital sign parameters will be
determined in each visit and change from Normal to Abnormal for physical evaluation will be
evaluated.
Immunogenicity Analysis
Samples for immunogenicity assessment (antidrug antibody [ADA] and neutralizing antibody
[nAb]) will be collected prior Pertuzumab administration in all visits. All patients in each
treatment arm will be assessed for ADA formation to Pertuzumab. In Institute Pasteur, with
validated kit, ADA formation will be detected and characterized. These tests will be done in 3
following steps:

A screening assay to detect anti-Pertuzumab antibodies;

A confirmatory assay for the samples that were positive in previous step

A titration assay to determine antibody titers
52


53


Monitoring
The purpose of monitoring is to assuring conducting the trial according to protocol and GCP
standards.
Monitor should prepare a written report for each visit to sponsor and PI. This report should
include monitor’s name, date of visit, center name, summary of visit, important findings,
deviations, final conclusion, and CAPA.
Site Initiation Visit (SIV)
SIV will be performed to ensure that the facility and medications required for the trial are
available in the study site and the investigators and staff involved in the study are aware of
study objectives and GCP principles.
In the SIV, the role of the monitor, CRA, project manager, and the auditor will be defined
clearly. After the introduction of the roles and responsibilities, staff will be taught the protocol
details including timelines, sample size, eligibility criteria, protocol conformity, deviation, and
reporting. The training should be documented. The eCRF details, ICD process, source
documentation, randomization and serious adverse event reporting will be discussed and
documented as well.
Site Monitoring Visit
Site monitoring visit will be performed to ensure the conduct of the study according to
approved protocol and GCP principles.
Before the trial starts, monitoring visits will be planned for each study site and will be
confirmed by the PI and other investigators through email or letter. The monitoring visits
during the study will be scheduled in order to visit when the planned recruitment of patients
will be in its 30% and 70% progress. Sponsor is responsible for the 30% monitoring visit and
“Trial” CRO is in charge of the 70% visit. In each visit, study elements will be monitored
including source data, consent forms, trial medicinal products accountability, adverse events,
protocol compliance, team qualification, and training. The monitoring report will be prepared
and reported to both PI and sponsor preferably in an arranged meeting.
54


Study Close-Out
Study close-out visit will be performed to ensure the proper documentation of the data and
return of the medicinal product and the equipments related to the trial.
After the last visit of the last participant, site close-out will be scheduled in a meeting and
in the presence of the investigator. The site close-out visit will start with a brief meeting
with the investigator and a decision will be made regarding the disposal of the remaining
investigational medicinal product. The study documents will be archived at the trial site.
A copy all safety reports will remain with the investigator and one copy will be rendered
to the sponsor. There will be a brief closure meeting with the investigator at the site and
the site close-out report will be prepared after the visit.
55


Adverse Events
Adverse Event will be considered any medical event presented by the subjects involved in the
study, which do not necessarily have a causal relation with the treatment in study. It will be
reported as an adverse effect any symptom, sign (including any abnormal laboratory
determination) or temporary disease associated to the use if the drug in study, whether they are
or not etiologically related to it. The medical conditions present before the beginning of the
study will only be considered as adverse events if they worsen during the study and cannot be
attributable to the natural evolution of the disease.
Adverse drug reaction (ADR)—The World Health Organization defines an ADR as “any
response to a drug which is noxious and unintended, and which occurs at doses normally used
in man for prophylaxis, diagnosis, or therapy of disease, or for the modification of
physiological function.”
AEs will be considered a Serious Adverse Event (SAE) if the event:
Results in death;
Implies a death risk;
Requires hospitalization;
Extends prior hospitalization;
Results in persistent or significant incapacity;
Produces a congenital anomaly or malformation, or
Requires medical or surgical intervention to avoid a permanent damage.
AEs Classification Based on Severity:
AEs will be classified according to its severity in relation to the guidelines established in the
Common Terminology Criteria for Adverse Events (CTCAE, version 5.0, published on
November 27, 2017). Grade refers to the severity of the AE. The CTCAE displays Grades 1
through 5 with unique clinical descriptions of severity for each AE based on this general
guideline:
Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only;
intervention not indicated.
Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting
ageappropriate instrumental ADL*.
56


Grade 3: Severe or medically significant but not immediately life-threatening;
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care
ADL**.
Grade 4: Life-threatening consequences; urgent intervention indicated.
Grade 5: Death related to AE.
* A Semi-colon indicates ‘or’ within the description of the grade.
* Activities of Daily Living (ADL)
*Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the
telephone, managing money, etc.
**Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet,
taking medications, and not bedridden.
AE classification based on its relation with the treatment (Causality assessment):
In order to establish the relation between the AE or the DAR and the treatment in study,
the following definitions will be considered:
Certain: a clinical event including alterations in the laboratory tests manifesting with
a reasonable temporal sequence related to the administration of the drug and cannot be
explained by the current disease, or by other drugs or substances. The response to the
drug suppression (released; dechallenge) should be clinically plausible. The event
should be final from a pharmacological point of view, using, if necessary, a conclusive
re-exposure procedure.
Probable/Likely: a clinical event, including alterations in the laboratory tests
manifesting with a reasonable temporal sequence related to the administration of the
drug, which is unlikely to be attributed to the current disease, or other drugs and
substances, and which when releasing the drug (dechallenge) a clinically reasonable
response appears. No information on re-exposure (rechallenge) is required to assign
this definition.
Possible: a clinical event, including alteration in the laboratory tests manifesting with
a reasonable temporal sequence related to the administration of the drug, but can also
be explained by the concurrent disease, or by other drugs and substances. The
information regarding the release of the drug may be missing or unclear.
57


Unlikely: a clinical event, including alterations in the laboratory tests manifesting with
an improbable temporal sequence related to the administration of the drug, and can be
explained in a more plausible way by the concurrent disease, or by other drugs or
substances.
Conditional/Unclassified: a clinical event, including alterations in the laboratory tests,
notified as an adverse reaction, of which it is essential to obtain more data in order to
make a proper evaluation, or the additional data are under examination.
Non evaluable/Unclassifiable: a notification that suggests an adverse reaction, but
cannot be judged because the information is insufficient or contradictory and cannot be
verified or completed in its data.
58


AEs Recording
All the undesirable and unexpected AEs that follow the administration of the drug will be
accurately recorded in the medical record of the patient and in the corresponding section of the
CRF. The event description should be recorded, as well as the temporal sequence regarding to
the administration of the drug, its duration, the procedures performed for the diagnosis if
appropriate, the results of the repeated exposure and the qualification made by the Researcher
as regards its severity and its relation to the administered drug.
AE Reporting Responsibilities
Principle Investigator Responsibilities
The investigator must report any SAE/R, which results in death or is life-threatening, to the
sponsor and IEC within the maximum of 24 hours by fax, email or etc.
The investigator must immediately and not later than seven calendar days report those
SAE/Rs which are not life-threatening or do not result in death but may put subjects in
danger or require intervention (medical or surgical) to prevent life-threatening outcomes.
These SAE/R need to be reported to the sponsor and IEC as soon as possible but not later
than seven calendar days of having taken notice of the SAE/R.
The investigator should report to the sponsor and IEC all predictable adverse events of
investigational medicinal product including for example injection site reactions, in case of
patient withdrawal from study or adverse event with a greater frequency than expected.
Sponsor Responsibilities
SUSARs which result in death, or are life-threatening; need to be reported by the sponsor
as soon as possible but not later than seven calendar days, to IEC and IFDA, using CIOMS
form (Suspect Adverse Reaction Report Form). A follow-up report is to be submitted within
15 calendar days.
The sponsor must report SUSARs which are not life-threatening or do not result in death,
but may put subjects in danger or require intervention (medical or surgical) to prevent life-
threatening outcomes, as soon as possible but not later than 15 calendar days, to IEC and
IFDA, using CIOMS form (Suspect Adverse Reaction Report Form). The follow-up report
considering the relation between the investigational medicinal product and an adverse event
is to be submitted as soon as possible.
59


All the reports and follow-up results of SAE/R need to be reported to IFDA within maximum
15 calendar days after sponsor awareness of SAE/R.
If the severity or frequency of predictable adverse events, for example, injection site
reactions, results in patient withdrawal from the study, or in case of higher incidence than
expected, the sponsor must report it to IFDA within maximum 15 calendar days.
The sponsor must report all the information regarding the SAE and serious ADR that are
reported during the course of the study and recommendations of investigators related to
increasing of study risk for subjects to Food and Drug Administration of Iran within 15
calendar days.
The sponsor must report to IFDA all recommendations from investigators about possible
increased risk of adverse events or participants, within maximum 15 calendar days.
Follow-up
The Investigator should take all appropriate measures to ensure the safety of the patients,
notably he/she should follow up the outcome of any Adverse Events (clinical signs,
laboratory values or other, etc.) until the return to normal or consolidation of the patient's
condition;
In case of any Serious Adverse Event, the patient must be followed up until clinical recovery
is complete and laboratory results have returned to normal, or until progression has been
stabilized. This may imply that follow-up will continue after the patient has left the study
and that additional investigations may be requested by the Monitoring Team
In case of any SAE brought to the attention of the Investigator at any time after cessation of
Investigational Product and considered by him/her to be caused by the Investigational
Product with a reasonable possibility, this should be reported to the Monitoring Team.
60


Withdrawal of patients
Participants may be withdrawn from the study for any of the following reasons:
Withdrawal of consent by the patient
Noncompliance, including refusal of study medical requirements, refusal of procedures as
stated in the study protocol, or use of prohibited medications
In the case of suspected pregnancy, a pregnancy test for Beta hCG will be requested, and
if the test is positive, the patient will be excluded from the study
Any hematologic, hepatic or renal AEs which needs cessation of study treatment
The occurrence of an undesirable event that causes the investigator to consider the
patient's exclusion from the study
Not possible to follow the patient's condition (Loss to follow-up)

Appendix 1: Informed Consent Form
Informed Consent Form
A Phase III, randomized, two armed, parallel, triple-blind, active controlled, equivalency
clinical trial to determine the therapeutic efficacy and safety between Pertuzumab®
(Manufactured by CinnaGen Co.) compared with active control group treated by Perjeta®
(Pertuzumab, the reference drug, Manufactured by Genentech) in neoadjuvant treatment of
HER 2 positive Breast Cancer patients
Mrs./Miss ………………………………
We invite you to participate in the above-mentioned clinical study. Information about this research is
provided in this sheet, and you are free to join this research or not.
You do not have to make an immediate decision and you are given a deadline to announce your opinion
after consulting the research team and anyone you desire, about participation and your involvement in
this research is entirely voluntarily. Before signing this consent, make sure that you understand all the
information
in
this
form
and
all
of
your
questions
are
answered.
Investigator:
1) I know that purposes of this research are evaluation of the efficacy and safety of Pertuzumab
(Manufactured by CinnaGen Co.) compared to Perjeta® (Manufactured by Genentech)
2) I know that my participation in this study is voluntary and I am not obligated to participate in this
research. I was assured that if I were not willing to participate in this research, I would not be
deprived of routine diagnostic and therapeutic care and my therapeutic relationship with the health
center and my physician will not get affected.
3) I know that even after agreeing to participate in the research, I can resign freely at any time after
informing the researcher, without giving any reason and my withdrawal from the research will not
deprive me of the usual treatment services.
4) This is how my participation is in this study:
Whenever the physician diagnosed that I need to receive Pertuzumab to improve my clinical
conditions, and I consented to receive it, treatment regimen according to the study protocol of will
66


be started and I will allocated in one of the treatment group (one of the treatment group receive
Pertuzumab (Manufactured by CinnaGen Co.) and the next group will receive Perjeta®
(Manufactured by Genentech)). During the study, I have to go to trial site in order to get my treatment
drugs, laboratory test and other interventions of visits. The activity of visits of study include:
Duration of study is 18-20 weeks with pathological sampling test after surgery. With considering
screening visit, I will have 8 visits (each visit is about 15 min without considering time of drug
administration) in this study. The difference between screening and first visit (treatment visit) is
maximum 2 weeks and the difference between other visits is 3 weeks. In screening visit, my health
condition, medical history, height, weight and vital sign will be evaluated by physician. In addition,
one blood sampling (3-5 mm) for general and specific laboratory test (CBC diff,. BUN, Cr, Bilirubin,
ALP, AST, ALT, NA, K, Mg, Ca, P, Cl, Albumin, Glucose, LDH, INR, PTT/aPTT, HIV, HCV,
HBs-Ag, assessment of antibody formation against drug, Unrine analysis, and pregnancy test if it is
required) will be drawn. Other evaluation include Echocardiography, MRI, and ECG. If all of my
lab results, imaging and clinical examination were confirmed by physician and I passed all eligibility
criteria of the study, I can enrolled in the study after signing this consent form. During the study I
will receive these drugs: in each treatment visits I will receive Carboplatin, Docetaxel, Trastuzumab
and one of the Pertuzumab drugs. I know that my allocation to each treatment group will be
randomly. My physician informed me that this blinding of the treatment is scientific and is to
evaluate the efficacy of the drugs. My physician informed me that all of the treatments and
interventions will be based on the routine treatment procedure and I do not need to have any extra
visit of clinic. Regardless of treatment group, I will receive all of the required interventions and
whenever participating in this study will considered not safe for me, I can discontinue the study and
will receive appropriate treatment after my quit. I know that all of the drugs of this study between
two treatment arms are similar and the only difference is related to Pertuzumab group.
In my next visits (visit 1-6), in each one of them, my health condition will be assessed by physician
(investigator). In each visit and before drug administration (every 3 weeks), one blood sampling will
be drawn in specified laboratory and these test include: CBC diff,. BUN, Cr, Bilirubin, ALP, AST,
ALT, NA, K, Mg, Ca, P, Cl, Albumin, Glucose, LDH, assessment of antibody formation against
drug (this test will be done with other lab test and there is no need to give extra blood sample).
In every 6 weeks interval (visit 3, 5, 7), echocardiography test is planned for me. In addition, in first
visit and last visit (visit 7) or any other visit that physician consider necessary, MRI test is planned
for me and there will be laboratory test in last visit which includes similar laboratory test with
previous visits.
In addition, in each visit, questions related to my health condition, other used drugs will be asked. I
know that laboratory and imaging test can be repeated based on the physician discretion.
I am assured that if in any time of the study, I had progress, I can discontinue the study and another
treatment will start for me based on the physician discretion. In addition, if I received less than 3
67


doses of pertuzumab (less than 3 cycle of 6 cycle) due to my condition, I will be withdrawan form
the study and new treatment based on the physician decision will be started for me.
By considering my health condition, I accept that during the study duration and 6 months after that, I
will not try to be pregnant and if there is a chance that I became pregnant or had delay in my
menstrual period, I will forthwith inform my physician (To be sure about pregnancy, there is
pregnancy test in screening, visit 3 and 6)
5) The possible benefits of my participation in this study are as follows:
Pertuzumab is one of the novel drug which has FDA and EMA approval for breast cancer indication.
The efficacy of Pertuzumab in breast cancer before and after surgery is confirmed and addition of this
drug to chemotherapy regimen can increase significantly clinical response without increasing AE
frequency. By participating in this study, I can receive pertuzumab while this drug is not easily
accessable in my country and I do not need to pay any cost for this drug. In addition, I will be examined
and evaluated by the physicians with greater precision and sensitivity regarding my condition and the
side effects of drugs. Also, the effects of my treatment will be carefully evaluated
6) The possible harms and adverse events of my participation in this research are as follows:
It is possible to experience these adverse events after participation in this study, including diarrhea,
cardia issue, hematologic issue, dermatologic issue, gastrointestinal issue, or reduce of white blood
cells, alopecia, nausea, vomiting (most commonly related to chemotherapy regimen drugs and not
necessarily related to Pertuzumab). The mentioned adverse events, can be occurred in both treatment
groups and can be observed by other chemotherapy regimen too. I have to remember that these adverse
events are temporary and after cessation of the tretamnet, all of these adverse events will be disappear
after specific time. In addition, if any AEs were occurred, I or my family should inform the physician as
soon as possible. This AE can be not related to the investigational drug of the study, but should be
reported to the physician of the study.
7) In the case of unwillingness to participate in the research, the usual services (therapeutic,
diagnostic, etc.) for me will be provided. My treatment will be based on the physician decision in
case of unwillingness to participate in the research
8) I know that the researchers of this study will keep all of my information confidential and are only
allowed to publish the overall and collective results of this research without mentioning my name
and my profile.
9) I know that the Ethical Committee in my study is allowed to have access to my information to
monitor my rights.
68


10) I know that I should not pay any costs of the trial drugs and tests including Chemotherapy regimen
drugs, Trastuzumab drugs, Pertuzumab drugs, Pegagen drugs, laboratory test, MRI,
Echocardiography, ECG, pathology test
11) Physician of the study and Mr. Siavash Bakhshian (sponsor representative) has been introduced to
me for answering my questions, and I was told that during the study any time a health problem
occurred to me or if I had a question regarding participation in this research, I can share with him
and ask for guidance.
12) I know that if during and after the research any physical and mental problems arose because of my
participation in this research, it will be the responsibility of the physician to treat the complications
and the related damages.
13) I know that if I have a problem or objection to executors of the research or the research process, I
can contact the ethic Committee of the Tehran University of Medical Sciences at the address of:
Room 605, 6th Floor, Central headquarters of Tehran University of Medical Sciences, Qods Street,

Appendix 3: RECIST 1.1
New response evaluation criteria in solid tumours: Revised RECIST
guideline (version 1.1)
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether
target or non-target) must have reduction in short axis to <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as
reference the baseline sum diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as
reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In
addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5
mm. (Note: the appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for
PD, taking as reference the smallest sum diameters while on study.
Evaluation of non-target lesions
Complete Response (CR): Disappearance of all non-target lesions and normalisation of tumour marker
level. All lymph nodes must be non-pathological in size (<10 mm short axis).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumour marker
level above the normal limits.
Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: the
appearance
of
one
or
more
new
lesions
is
also
considered
progression).

Objectives 
To verify the equivalency of Pertuzumab® (Manufactured by CinnaGen Co.) vs. Perjeta® (Pertuzumab, the 
reference drug, Manufactured by Genentech), in neoadjuvant treatment of HER 2 positive Breast Cancer 
patients. 
Primary objective(s): 
Primary objective of this study is to evaluate equivalence of Pertuzumab® (Manufactured by CinnaGen Co.) 
compared to the Perjeta® (Reference drug, Genentech), when added to Carboplatin+Docetaxel+Trastuzumab 
regimen, based on the pathological complete response (pCR) in neoadjuvant treatment setting in HER2+ breast 
cancer patients. 
Secondary objective(s): 
The secondary purposes of this study are to establish the total pathological complete response (tpCR), overall 
response rate (ORR), breast-conserving surgery (BCS) and assess safety of Pertuzumab® (Manufactured by 
CinnaGen Co.) group in comparison with Perjeta® (Reference drug, Genentech) group.

3.2. 
Randomization 
Patients will be dynamically randomized to different groups during the study using Minimization method 
(with a 90% random component). The two main variables on which the balance is performed will be as 
follows: 
1-ER/PR: ER/PR+, ER/PR-     
2-Type of breast cancer: operable, locally advanced, inflammatory   
At the beginning of the study, each patient will receive a unique code in order to be recognized during the 
study. The assigned code consists of 4 letters (corresponding to the first two letters of the first name and 
the first two letters of the surname), three digits (center code), the first three letters of the generic drug name 
(which is PER-) and 3 digits (corresponding to randomization code). For example: ABCD001PER-001. 
3.3. 
Sample size 
Using an equivalence margin of 0.2, a sample size of 96 subjects in each one of both Pertuzumab® 
(CinnaGen Co.) and Perjeta® (Genentech Co.) groups achieve 80% power to detect bioequivalence for the 
difference between groups. The actual difference is considered zero. The PCR efficacy for Perjeta® group 
is 0.66 (22, 24, 25). Two-way independent T-test with 5% significance level will be used to analyze the 
results. Considering 10% dropout, final sample size is considered 107 in each group.

Section 4: Statistical Principles 
4.1. 
Protocol Deviations 
4.1.1. Description of which protocol deviations will be summarized 
The number (and percentage) of patients with major and minor protocol deviations will be summarized by 
treatment group with details of type of deviation provided. No formal statistical testing will be undertaken. 
4.2. 
Analysis populations 
All tests of the effect of treatment on the primary outcome will be conducted on a per-protocol basis. The intent-
to-treat (ITT) patient population includes all patients who signed the informed consent form and underwent 
random assignment. The per-protocol set (PPS) population will be defined as the ITT population excluding 
patients who violated protocols to a considerable extent, including major protocol inclusion/exclusion criteria or 
treatment protocols. Slight deviations may be acceptable. The primary outcome was first evaluated in the PP 
population and then in the ITT population (with and without imputation) as a sensitivity analysis. In case there is 
no final answer, the worst-case scenario “NO PCR” will be applied. Then, the results will be compared and if 
there was any significant differences, the reason will be evaluated. The safety will be assessed in the as-treated 
population, which includes all patients who received at least one dose of the assigned trial treatment.

5.1. 
Recruitment (Information to be included in the CONSORT flow diagram) 
In the “CONSORT” diagram, the number of people screened, eligible, randomized and receiving their 
allocated treatment will be provided. 
5.1.1. Details of how baseline characteristics will be descriptively summarized 
Categorical data will be summarized by numbers and percentages. Continuous data will be summarized by mean 
and SD. Tests of statistical significance will not be reported for the baseline characteristics.

Section 6: Analysis 
6.1. 
Analysis methods 
6.1.1. What analysis method will be used, and how the treatment effects will be presented 
For the primary endpoint, comparison of pathologic complete response (pCR) rate, treatment differences in 
proportions will be calculated and p-value will be reported based on proportion test. Equivalence of Pertuzumab® 
(CinnaGen Co.) and Perjeta® will be concluded if the resulted 95% confidence interval for the difference will be 
within the predetermined range (-0.2, 0.2). 
For the secondary endpoints total Pathological complete response (tpCR), objective response rate (ORR) and 
breast conservation rate (BCS), frequency and proportions, and p-value will be reported based on proportion 
test. 
Adverse events will be reported as incidence rate. Safety will assess on the basis of reports of adverse events, 
laboratory test results, and vital sign measurements. Moreover, the causality assessment of ADR will be reported 
in two groups. 
6.1.2. List and describe each primary and secondary outcome including details of: methods 
used for assumptions to be checked for statistical methods 
   There is no assumption to check based on the proportion test. 
6.2. 
Statistical Software 
The analysis will be carried out using Stata version 14.
