Chimeric antigen receptor (CAR) T-cell therapies are increasingly providing options for care of oncology patients with advanced hematologic malignancies, which has led to two US FDA approvals. However, they are often associated with significant immune related adverse events that require prompt management. These toxicities are mainly cytokine release syndrome and neurotoxicity, and can be managed in an appropriate setting when presenting to nononcologists or internists. ⋯ A management approach can be determined by the severity of the toxicity. Tocilizumab, a humanized monoclonal antibody, was FDA approved for the treatment of cytokine release syndrome, and corticosteroids may be used. Neurotoxicity is generally managed with supportive care and steroidal therapy.

Multicenter Study
Olaparib maintenance monotherapy in platinum-sensitive, relapsed ovarian cancer without germline BRCA mutations: OPINION Phase IIIb study design.
The poly(ADP-ribose) polymerase inhibitor olaparib (Lynparza™) is approved for maintenance treatment of platinum-sensitive relapsed ovarian cancer. OPINION is a single-arm, open-label, multicenter, Phase IIIb study to assess the efficacy and safety of olaparib tablet maintenance therapy in women with high-grade serous or endometrioid platinum-sensitive relapsed ovarian cancer without a germline BRCA1 or BRCA2 mutation. ⋯ The primary end point is investigator-assessed progression-free survival; secondary end points include progression-free survival according to tumor homologous recombination deficiency status. Clinical trial registration: NCT03402841.

Randomized Controlled Trial
Targeted agents or immuno-oncology therapies as first-line therapy for BRAF-mutated metastatic melanoma: a real-world study.
Aim: Targeted therapy (TT) and immuno-oncology (IO) drugs are approved for patients with BRAF mutant metastatic melanoma (MM). We compared real-world outcomes for first-line (1L) TT versus 1L IO to evaluate optimal sequencing. Materials & methods: Physicians-identified BRAF mutant MM patients initiating 1L TT or IO therapies and extracted treatment, disease and clinical outcomes including disease response which were compared between TT and IO and individual regimens. ⋯ IO-treated had a RECIST-determined response rate of 45.9 versus 60.1% for TT and time on treatment of 7.2 versus 11.4 months, respectively. There was no survival difference between cohorts. Conclusion: Despite higher risk patients, 1L TT resulted in higher response rate and longer treatment duration suggesting a preferred 1L sequence.

Randomized Controlled Trial Multicenter Study
MONALEESA clinical program: a review of ribociclib use in different clinical settings.
Ribociclib has received approval in the pre/peri- and postmenopausal disease settings on the basis of the MONALEESA trials. MONALEESA-2 demonstrated that ribociclib plus letrozole significantly improved progression-free survival compared with placebo plus letrozole as first-line therapy in postmenopausal patients with HR-positive, HER2-negative advanced breast cancer. ⋯ This review summarizes the MONALEESA clinical program. ClinicalTrials.gov identifiers: NCT01958021 (MONALEESA-2), NCT02422615 (MONALEESA-3), NCT02278120 (MONALEESA-7).

The Bruton's tyrosine kinase inhibitor ibrutinib represents a highly effective single substance in the treatment of Waldenström's macroglobulinemia. Ibrutinib monotherapy is a valid therapeutic option either in the relapsed or refractory setting or in patients first line, particulary when they are ineligible for chemotherapy. However, the treatment success depends on the genotype. Recent data suggest that ibrutinib in combination with rituximab may partially overcome this genotype dependency.
