Sotorasib showed anticancer activity in patients with KRAS p.G12C-mutated advanced solid tumors in a phase 1 study, and particularly promising anticancer activity was observed in a subgroup of patients with non-small-cell lung cancer (NSCLC). ⋯ In this phase 2 trial, sotorasib therapy led to a durable clinical benefit without new safety signals in patients with previously treated KRAS p.G12C-mutated NSCLC.

Randomized Controlled Trial Multicenter Study
Adjuvant Olaparib for Patients with BRCA1- or BRCA2-Mutated Breast Cancer.
Poly(adenosine diphosphate-ribose) polymerase inhibitors target cancers with defects in homologous recombination repair by synthetic lethality. New therapies are needed to reduce recurrence in patients with BRCA1 or BRCA2 germline mutation-associated early breast cancer. ⋯ Among patients with high-risk, HER2-negative early breast cancer and germline BRCA1 or BRCA2 pathogenic or likely pathogenic variants, adjuvant olaparib after completion of local treatment and neoadjuvant or adjuvant chemotherapy was associated with significantly longer survival free of invasive or distant disease than was placebo. Olaparib had limited effects on global patient-reported quality of life. (Funded by the National Cancer Institute and AstraZeneca; OlympiA ClinicalTrials.gov number, NCT02032823.).

Randomized Controlled Trial Multicenter Study Comparative Study
Rituximab versus Mycophenolate Mofetil in Patients with Pemphigus Vulgaris.
Rituximab and mycophenolate mofetil are used to treat pemphigus vulgaris, but they have not been adequately compared in clinical trials. ⋯ Rituximab was superior to mycophenolate mofetil in producing sustained complete remission at 52 weeks in patients with pemphigus vulgaris. Rituximab resulted in a greater reduction in glucocorticoid use than mycophenolate mofetil, but more patients in the rituximab group had serious adverse events. Further trials are needed to determine the comparative efficacy and safety of rituximab and mycophenolate mofetil beyond 52 weeks of treatment. (Funded by F. Hoffmann-La Roche; PEMPHIX ClinicalTrials.gov number, NCT02383589.).

Randomized Controlled Trial Multicenter Study Comparative Study
Hypothermia versus Normothermia after Out-of-Hospital Cardiac Arrest.
Targeted temperature management is recommended for patients after cardiac arrest, but the supporting evidence is of low certainty. ⋯ In patients with coma after out-of-hospital cardiac arrest, targeted hypothermia did not lead to a lower incidence of death by 6 months than targeted normothermia.

Safety and Efficacy of Single-Dose Ad26.COV2.S Vaccine against Covid-19.
The Ad26.COV2.S vaccine is a recombinant, replication-incompetent human adenovirus type 26 vector encoding full-length severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein in a prefusion-stabilized conformation. ⋯ A single dose of Ad26.COV2.S protected against symptomatic Covid-19 and asymptomatic SARS-CoV-2 infection and was effective against severe-critical disease, including hospitalization and death. Safety appeared to be similar to that in other phase 3 trials of Covid-19 vaccines. (Funded by Janssen Research and Development and others; ENSEMBLE ClinicalTrials.gov number, NCT04505722.).
