Purpose: Telisotuzumab vedotin (Teliso-V) is a c-Met-directed antibody-drug conjugate with a monomethyl auristatin E cytotoxic payload. The phase II LUMINOSITY trial (ClinicalTrials.gov identifier: NCT03539536) aimed to identify the optimal c-Met protein-overexpressing non-small cell lung cancer (NSCLC) population for treatment with Teliso-V (stage I) and expand the selected group for efficacy evaluation (stage II).

We now report final overall survival (OS) data.
Methods: BROCADE3 is a randomized phase 3 study that enrolled patients with BRCA1/2-mutated, HER2-negative advanced breast cancer who received ≤ 2 prior lines of chemotherapy for metastatic disease.
Article Synopsis
- The phase 3 VELIA trial tested the effectiveness of veliparib combined with carboplatin and paclitaxel as a treatment and maintenance option for patients with high-grade serous ovarian carcinoma.
- In a subgroup analysis of 78 Japanese patients, those receiving vtreatment with veliparib showed a median progression-free survival of 27.4 months compared to 19.1 months for the control group, although the results were not statistically significant.
- The study noted differences in the rates of severe side effects between Japanese and non-Japanese patients, suggesting the need for tailored management strategies during treatment.
BRCA-Mutated Advanced Breast Cancer (BROCADE3) is a phase 3 study, evaluating veliparib in combination with carboplatin/paclitaxel with continuation as monotherapy if carboplatin/paclitaxel is discontinued in patients with germline BRCA1/2 mutation-associated, advanced human epidermal growth factor receptor 2-negative breast cancer. The objective of the current analysis was to characterize the veliparib exposure-response relationships for efficacy (progression-free survival [PFS]) and safety in this study. Exposure-efficacy analyses of PFS were conducted using Kaplan-Meier plots and cox proportional hazards (CPH) models using treatment alone or both treatment and exposure as time-dependent predictors to estimate the effect of veliparib in combination with carboplatin/paclitaxel and as monotherapy.

Objective: In the Phase 3 VELIA trial (NCT02470585), veliparib added to carboplatin plus paclitaxel concomitantly and as maintenance for women with newly-diagnosed advanced ovarian cancer significantly improved progression-free survival (PFS) versus chemotherapy alone. Here we present exploratory analyses by paclitaxel dosing schedule and germline BRCA (gBRCA) status.
Methods: Women with untreated ovarian carcinoma were randomized (1:1:1) to: veliparib during chemotherapy and maintenance (veliparib-throughout), veliparib during chemotherapy followed by placebo maintenance (veliparib-combination only), or placebo during chemotherapy and maintenance (control).
