Assessing Real-World Racial Differences Among Patients With Metastatic Triple-Negative Breast Cancer in US Community Practices.

Objective: Real-world data characterizing differences between African American (AA) and White women with metastatic triple-negative breast cancer (mTNBC) are limited. Using 9 years of data collected from community practices throughout the United States, we assessed racial differences in the proportion of patients with mTNBC, and their characteristics, treatment, and overall survival (OS).

Methods: This retrospective study analyzed de-identified data from 2,116 patients with mTNBC in the Flatiron Health database (January 2011 to March 2020).

Safety and immunovirologic outcomes with maraviroc combination regimens in patients with a history of past treatment failures and virologic resistance in Brazil: an open-label, multicenter phase 3b study.

Maraviroc is a first-in-class chemokine coreceptor type-5 (CCR5) antagonist with demonstrated immunovirologic activity in treatment-experienced (TE) patients with CCR5 (R5)-tropic HIV-1; however, experience in regimens containing newer antiretroviral agents is limited. The primary objective of this 96-week open-label, noncomparative, multicenter Phase 3b study (NCT00478231) was to assess the safety of maraviroc in combination with optimized background therapy (OBT), which could include recently introduced agents such as darunavir and raltegravir in TE patients in Brazil with R5 HIV-1 and limited therapeutic options. Immunovirologic activity was a secondary endpoint.
