PURPOSE Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer. Early-stage, high-risk patients with TNBC are treated with chemotherapy and pembrolizumab per the KEYNOTE-522 regimen. This report examines real-world clinical effectiveness and toxicity of this regimen. METHODS This 19-site retrospective analysis included all patients who received at least one dose of the KEYNOTE-522 regimen. Safety, efficacy, and health care encounters were collected. RESULTS 675 patients from 19 sites in the United States who received chemotherapy and pembrolizumab for early-stage TNBC were included. 547 (81.0%) patients underwent surgery and 250 (54.7%) patients had a pathologic complete response (pCR). No baseline characteristics were predictive of pCR status. 224 patients (33.2%) had an adverse drug event resulting in ≥1 dose reduction of chemotherapy and were significantly more likely to have residual disease. Immune-related adverse events (irAEs) were observed in 388 (57.5%) patients and grade 3+ irAEs were observed in 176 (26.1%) patients. There was no difference in pCR status between provider's choice chemotherapy schedules. There was no difference of pCR rate between Black and White patients (55.6% v 51.6%, P = .489). White patients were significantly more likely to have any grade and grade 3+ irAEs. Older patients (age ≥65 years) had similar pCR rates compared with younger patients; however, older patients were significantly more likely to have grade 3+ irAEs. CONCLUSIONS In this multi-institutional real-world cohort, we observed a lower pCR rate, higher rates of toxicity, frequent emergency health care utilization, and the reporting of rare irAEs at higher frequency than the KEYNOTE-522 regimen. These findings have important implications for clinical management of patients with early-stage TNBC and warrant further validation with real-world data sets.

ABSTRACT Interactions between clinical pharmacists and industry partners continue to evolve as health care increases in complexity and technology assumes a more dominant role. To address the corresponding ethical challenges, the 2025 Industry Relations Committee of the American College of Clinical Pharmacy (ACCP) was charged with updating the 2008 ACCP position statement, Pharmacists and Industry: Guidelines for Ethical Interactions . This update expands its perspective, reflecting the broader and more influential roles pharmacists play across the health care ecosystem. All clinical pharmacist–industry interactions should be grounded in improving patient care. Through this lens, six recommendations are provided: (1) Pharmacists should not engage in industry partnerships or collaborations that might unduly influence objectivity, independence, or fairness in clinical and professional judgments; (2) Pharmacists should disclose and mitigate financial, consulting, or other relationships that constitute potential conflicts of interest and should not participate in activities where an existing conflict cannot be resolved; (3) Pharmacists who participate in industry‐sponsored research should follow accepted ethical, regulatory, and scientific standards; (4) Pharmacists providing continuing education programs or developing drug information materials should maintain control of content; ensure their content is fair, balanced, and free from bias; and disclose and mitigate any conflicts; (5) Formal instruction on ethical interactions with industry professionals should begin early and continue through all stages of pharmacist education, training, and professional development; (6) Pharmacists should maintain the confidentiality and privacy of patients and other health care professionals when working with industry partners. Questions to guide personal industry interactions are provided. This paper does not detail every emerging area (e.g., artificial intelligence, social media), but recommendations are applicable wherever clinical pharmacists leverage their professional expertise. By maintaining a critical, discerning, and ethical approach to industry collaborations, clinical pharmacists can uphold professional obligations while contributing to the advancement of evidence‐based practice, ultimately prioritizing patient welfare.
