About This Trial

Background Information and Rationale: Trastuzumab is a humanized monoclonal antibody that acts extracellularly on the erbB-2 receptor.Trastuzumab is a recombinant humanized IgG1 monoclonal antibody against the human epidermal growth factor receptor 2 (HER2/erbB-2),which has shown in both in vitro assays and in animals, to inhibit the proliferation of human tumour cells that overexpress erbB-2. Additionally, trastuzumab is a potent mediator of antibody-dependent cell-mediated cytotoxicity (ADCC). In vitro, trastuzumab-mediated ADCC has been shown to be preferentially exerted on erbB-2 overexpressing cancer cells compared with cancer cells that do not overexpress erbB-2. Trastuzumab has emerged as a widely accepted standard of care for erbB-2-positive disease. (Metastatic/ adjuvant/neoadjuvant. Our current hypothesis suggests that the cells which are disseminated at the time of surgery will encounter an inhospitable environment which will be anti-HER in nature. Therefore combining the above mentioned streams of thought, we would like to assess the effect of a short pre-operative course of Trastuzumab on breast cancer relapse. The study is proposed in HER2 positive patients with operable breast cancer. Objectives : Primary: The primary objective of the study is to see the effect of short duration of peri-operative Trastuzumab on disease-free survival in comparison in all patients Secondary: The safety of the pre-operative therapies including the early post operative morbidity 1. Overall survival (OS) in all patients and in pathologically node positive patients. 2. The level of circulating tumor cells (CTCs) in the peripheral blood assessed before starting pre-operative therapy and at the same time point in the control arm, level of CTCs 10 minutes prior to start of surgery, during surgery and 10 days after surgery on 40 consecutive consenting patients (20 in each arm). The levels of circulating chromatin will also be estimated at the same time points as CTC for these 40 patients. 3. Evaluation of the paraffin blocks for pTEN loss6-8 and p95ErbB2 truncated form of HER2 on 100 consecutive consenting patients (50 in each arm).9-11 Study Design : This is phase 3, randomized Double blinded parallel group study of Trastuzumab in pre operative setting in operable breast cancer patients. Approximately 1000 patients with Women with HER2neu positive, T1/T2/T3 and N0/N1. clinical T4 and/or N2 disease who are considered operable by the treating surgeon with histopathological diagnosis on core biopsies, will be included in the study. Patients with T4 or N2 (locally advanced and large operable for neo-adjuvant chemotherapy) will not be included. All node positive patients will receive single injection of Depot Inj. Progesterone 500 mg deep IM 4 -14 days prior to surgery Patients will be stratified, before randomization for Tumor size, menopausal status, and affordability for Trastuzumab and centre of the study. These patients will then be randomized 1:1 to receive the following Intervention arm: .A single dose of Trastuzumab (Herceptin, Hoffman La Roche) at 8 mg/Kg as a 90 minute intravenous infusion in 250 ml of normal saline, in the window period of 10-15 4 to 14 days (both days inclusive) prior to the planned date of surgery. Control arm: A 90 minute intravenous infusion of saline as placebo All patients will thereafter receive standard post-operative adjuvant therapy as per local institutional practice including hormonal therapy, chemotherapy and radiation therapy.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Carcinoma Breast Stage I, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 1,100 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
