We used the simian immunodeficiency virus (SIV)/rhesus macaque model to study events that underlie sexual transmission of human type 1 (HIV-1). Four female rhesus macaques were inoculated intravaginally with SIVmac251, and then killed 2, 5, 7, 9 d later. A technique detected polymerase chain reaction-amplified SIV in situ showed first cellular targets for lamina propria cervicovaginal mucosa, immediately subjacent epithelium. Phenotypic localization studies demonstrated many infected cells...

Crizotinib confers improved progression-free survival compared with chemotherapy in anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC), but progression invariably occurs. We investigated the efficacy and safety of alectinib, a potent selective ALK inhibitor excellent CNS penetration, patients crizotinib-refractory ALK-positive NSCLC.Alectinib 600 mg was administered orally twice daily. The primary end point objective response rate (ORR) by central independent...

Non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion (Exon20ins) mutations exhibits inherent resistance to approved tyrosine kinase inhibitors. Amivantamab, an EGFR-MET bispecific antibody immune cell-directing activity, binds each receptor's extracellular domain, bypassing at the inhibitor binding site.CHRYSALIS is a phase I, open-label, dose-escalation, and dose-expansion study, which included population EGFR Exon20ins NSCLC. The primary end...

Adagrasib, an oral small-molecule inhibitor of mutant KRAS G12C protein, has shown clinical activity in pretreated patients with several tumor types, including colorectal cancer. Preclinical studies suggest that combining a epidermal growth factor receptor antibody could be effective strategy.In this phase 1-2, open-label, nonrandomized trial, we assigned heavily metastatic cancer to receive adagrasib monotherapy (600 mg orally twice daily) or (at the same dose) combination intravenous...
