The OlympiAD Phase III study (NCT02000622) established the clinical benefits of olaparib tablet monotherapy (300 mg twice daily) over chemotherapy treatment of physician’s choice (TPC) in patients with a germline BRCA1/2 mutation (gBRCAm) and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who had received ≤2 chemotherapy lines in the metastatic setting. Here, we report pre-specified analyses of data from Asian (China, Japan, Korea and Taiwan) patients in the study. All patients were randomized 2:1 to olaparib tablets (300 mg twice daily) or single-agent chemotherapy TPC (21-day cycles of either capecitabine, eribulin or vinorelbine). The primary endpoint was progression-free survival assessed by blinded independent central review. The prevalence of gBRCAm in the OlympiAD Asian subgroup screened for study recruitment was 13.5%. Patient demographics and disease characteristics of the Asian subgroup (87/302 patients) were generally well balanced between treatment arms. Asian patients in the olaparib arm achieved longer median progression-free survival, assessed by blinded independent central review, versus the chemotherapy TPC arm (5.7 vs 4.2 months; HR = 0.53 [95% CI: 0.29–0.97]), which was consistent with findings in the global OlympiAD study population. Findings on secondary efficacy and safety/tolerability outcome measures in Asian patients were also similar to those observed in the global OlympiAD study population. The OlympiAD study was not powered to detect race-related differences between treatment groups; however, the consistency of our findings with the global OlympiAD study population suggests that previously reported findings are generalizable to Asian patients.

This trial compared the efficacy of antiplatelet therapy with prasugrel or clopidogrel in patients with non–ST-segment elevation MI or unstable angina. Although prasugrel provides more intense platelet inhibition, clinical outcomes were similar with the two drugs. Clinical-practice guidelines for patients with acute coronary syndromes consisting of unstable angina or myocardial infarction without ST-segment elevation recommend a strategy of early invasive management (angiography within 48 to 72 hours with provisional revascularization) for patients at moderate to high risk. 1 , 2 However, analyses from clinical trials and national registries have shown that many such patients are treated medically without revascularization and that such patients have poorer long-term cardiovascular outcomes than those who undergo revascularization. 3 – 6 Even though patients with acute coronary syndromes who receive only medical therapy have an increased-risk profile, they have been underrepresented in large-scale, contemporary, randomized . . .

Up to 30% of patients with metastatic castration-resistant prostate cancer have deleterious mutations in genes involved in homologous recombination repair of DNA damage. The use of the PARP inhibitor olaparib in such patients was associated with longer progression-free survival and a longer time to pain progression than control therapy.

In an open-label, randomized, noninferiority trial, dolutegravir-based antiretroviral therapy was compared with standard care in children and adolescents starting first- or second-line therapy for HIV type 1 infection. Dolutegravir-based ART was superior to standard-care ART.

In a multicenter trial in 566 patients with critical illness who had delirium, the use of haloperidol or ziprasidone, as compared with placebo, had no significant effect on the duration of delirium or coma. Side effects and extrapyramidal disorders occurred at similar rates in all groups.

Among patients who had mutations in BRCA1 or BRCA2 and were at high risk for disease progression, those who were assigned to a year of olaparib adjuvant therapy had 3-year invasive disease–free survival of 86%, as compared with 77% among those who were assigned to placebo. Few patients stopped olaparib owing to side effects.

The PROfound trial showed that olaparib prolonged imaging-based progression-free survival among patients whose tumors contained defects in the homologous recombination repair genes BRCA1 , BRCA2 , or ATM . With longer follow-up, the trial now shows that olaparib prolonged overall survival in these patients. Toxic effects included anemia, nausea, and asthenia.

In 556 patients with previously untreated lung cancer bearing EGFR mutations, osimertinib and the first-generation EGFR inhibitors erlotinib and gefitinib had similar response rates, but osimertinib resulted in longer progression-free survival and had somewhat less toxicity.

In women with hormone-receptor–positive metastatic breast cancer that had progressed after endocrine therapy, palbociclib plus fulvestrant was associated with progression-free survival of more than 9 months, as compared with less than 4 months with fulvestrant alone. Approximately 80% of breast cancers express estrogen receptors, progesterone receptors, or both. Endocrine therapies are the mainstay of treatment for these hormone-receptor–positive cancers, substantially reducing the relapse rate after presentation with early-stage cancer. 1 Despite advances in endocrine therapy, many women have a relapse during or after completing adjuvant therapy. The care of these women remains a considerable clinical challenge. Single-agent treatment with an aromatase inhibitor or tamoxifen has shown limited clinical benefit. 2 , 3 The selective estrogen-receptor degrader fulvestrant has modest activity in this population of patients, 4 , 5 and the development of effective therapies that can reverse resistance to endocrine therapy . . .

PROpel met its primary endpoint showing statistically significant improvement in radiographic progression-free survival with olaparib plus abiraterone versus placebo plus abiraterone in patients with first-line metastatic castration-resistant prostate cancer (mCRPC) unselected by homologous recombination repair mutation (HRRm) status, with benefit observed in all prespecified subgroups. Here we report the final prespecified overall survival analysis. This was a randomised, double-blind, phase 3 trial done at 126 centres in 17 countries worldwide. Patients with mCRPC aged at least 18 years, Eastern Cooperative Oncology Group performance status 0–1, a life expectancy of at least 6 months, with no previous systemic treatment for mCRPC and unselected by HRRm status were randomly assigned (1:1) centrally by means of an interactive voice response system–interactive web response system to abiraterone acetate (orally, 1000 mg once daily) plus prednisone or prednisolone with either olaparib (orally, 300 mg twice daily) or placebo. The patients, the investigator, and study centre staff were masked to drug allocation. Stratification factors were site of metastases and previous docetaxel at metastatic hormone-sensitive cancer stage. Radiographic progression-free survival was the primary endpoint and overall survival was a key secondary endpoint with alpha-control (alpha-threshold at prespecified final analysis: 0·0377 [two-sided]), evaluated in the intention-to-treat population. Safety was evaluated in all patients who received at least one dose of a study drug. This study is registered with ClinicalTrials.gov, NCT03732820, and is completed and no longer recruiting. Between Oct 31, 2018 and March 11, 2020, 1103 patients were screened, of whom 399 were randomly assigned to olaparib plus abiraterone and 397 to placebo plus abiraterone. Median follow-up for overall survival in patients with censored data was 36·6 months (IQR 34·1–40·3) for olaparib plus abiraterone and 36·5 months (33·8–40·3) for placebo plus abiraterone. Median overall survival was 42·1 months (95% CI 38·4–not reached) with olaparib plus abiraterone and 34·7 months (31·0–39·3) with placebo plus abiraterone (hazard ratio 0·81, 95% CI 0·67–1·00; p=0·054). The most common grade 3–4 adverse event was anaemia reported in 64 (16%) of 398 patients in the olaparib plus abiraterone and 13 (3%) of 396 patients in the placebo plus abiraterone group. Serious adverse events were reported in 161 (40%) in the olaparib plus abiraterone group and 126 (32%) in the placebo plus abiraterone group. One death in the placebo plus abiraterone group, from interstitial lung disease, was considered treatment related. Overall survival was not significantly different between treatment groups at this final prespecified analysis. Supported by AstraZeneca and Merck Sharp & Dohme.
