Rucaparib camsylate (CO-338; 8-fluoro-2-{4-[(methylamino)methyl]phenyl}-1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one ((1S,4R)-7,7-dimethyl-2-oxobicyclo[2.2.1]hept-1-yl)methanesulfonic acid salt) is a PARP1, 2 and 3 inhibitor. Phase I studies identified a recommended Phase II dose of 600 mg orally twice daily. ⋯ Comparable to rucaparib development, other PARP inhibitors, such as olaparib, niraparib, veliparib and talazoparib, are developing CDx tests for targeted therapy. PARP inhibitor clinical trials and CDx assays are discussed in this review, as are potential PARP inhibitor combination therapies and likely resistance mechanisms.

Inhibitory ligands on tumor cells and their corresponding receptors on T cells are collectively called immune checkpoint molecules and have emerged as druggable targets that harness endogenous immunity to fight cancer. Immune checkpoint inhibitors targeting CTLA-4, PD-1 and PD-L1 have been developed for the treatment of patients with non-small-cell lung cancer and other malignancies, with impressive clinical activity, durable responses and a favorable toxicity profile. ⋯ The efficacy and safety data for drugs such as ipilimumab, nivolumab, pembrolizumab, atezolizumab and durvalumab are reviewed, along with combination strategies and response evaluation criteria. The toxicity profiles and predictive biomarkers of response are also discussed.

Review Meta Analysis
Rolapitant: a pooled analysis of its efficacy and safety in the prophylaxis of chemotherapy-induced nausea and vomiting.
We conducted a pooled analysis of rolapitant-containing regimens versus control in the prophylaxis of chemotherapy-induced nausea and vomiting. ⋯ Rolapitant-based regimens are associated with higher rates of complete response, no significant nausea and no emesis with highly/moderately emetogenic chemotherapy compared with control regimens.
