A Study of Pertuzumab in Combination With Herceptin in Patients With HER2 Positive Breast Cancer.

Draft scope assessment: unclear. Attached because the study's own record names HER2 and names HER2. The study was not selected for this indication by its sponsor, and its eligibility has not been reconciled against this page in full. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

primary · POSTED

pCR was defined as an absence of invasive neoplastic cells at microscopic examination of the tumor remnants after surgery following primary systemic therapy. Based on the type of breast cancer participants were categorized as those with 1. Operable breast cancer, 2. Inflammatory breast cancer and 3. Locally advanced breast cancer. Participants with invalid/missing pCR assessments were defined as non-responders.

ITT Population; Analysis was performed according to initial randomization. Number (n) equal (=) number of participants included in the specified type of breast cancer.

pCR was defined as an absence of invasive neoplastic cells at microscopic examination of the tumor remnants after surgery following primary systemic therapy. Participants were classified as Estrogen and/or Progesterone positive (+ve), Estrogen and/or Progesterone negative (-ve) or receptor status unknown. Participants with invalid/missing pCR assessments were defined as non-responders.

ITT Population; Analysis was performed according to initial randomization. n = number of participants included in the specified hormone receptor status.

secondary · POSTED

Tumor assessments were made based upon the Response Evaluation Criteria in Solid Tumors (RECIST) criteria - version 1.0. The clinical response at each cycle up to the last assessment prior to surgery was derived for primary breast tumor using the following algorithm: CR: if measurement of '0' is noted at a given cycle as compared to baseline measurement which is greater than (\>)0 at screening or cycle 1 Day 1; PR: if measurement is at least a 30 percent (%) decreased compared to baseline levels . (Reference= baseline size or sum of sizes); SD: if measurement at a given cycle is not sufficient shrinkage to qualify for neither PR nor sufficient increase to qualify for PD compared to baseline levels. PD: if lesion is at least a 20 % increase from measurements at baseline.

ITT Population; Analysis was performed according to initial randomization. Number of participants analyzed = participants evaluable for this outcome.
