Findings from the phase 1 CHRYSALIS study showed that patients with advanced EGFR-mutant non–small cell lung cancer who were treatment naïve or resistant to osimertinib therapy had high response rates when treated with the combination of amivantamab and lazertinib.

Positive safety, pharmacokinetic, and pharmacodynamic data were reported for the first-in-human phase 1 dose-escalation trial of MGD019 during the European Society for Medical Oncology Virtual Congress 2020 as well as preliminary antitumor activity in select tumor types.

Patients with NTRK fusion–positive solid tumors and baseline CNS metastases demonstrated durable intracranial activity with entrectinib, according to results of a small subpopulation analysis presented at the 2020 ESMO Virtual Congress.

Patients with completely resected stage IIIAN2 non–small cell lung cancer should not be recommended for post-operative radiotherapy, according to results from the phase 3 LungART trial that were presented during the ESMO Virtual Congress 2020, due to nonstatistically significant increase in disease-free survival versus those treated in the control group.

Findings from the phase 3 monarchE trial reported at the ESMO Virtual Congress 2020 showed that the risk of invasive disease with ​abemaciclib plus endocrine therapy was significantly reduced versus endocrine therapy alone in patients with high-risk early hormone receptor-positive, HER2-negative breast cancer.

Petros Grivas, MD, PhD, discusses the challenge with biomarker discovery currently in the treatment landscape of urothelial carcinoma.

The pathologic complete responses were significantly improved with neoadjuvant atezolizumab in combination with nab-paclitaxel plus doxorubicin and cyclophosphamide compared with placebo and chemotherapyin patients with stage 2 or stage 3 triple-negative breast cancer.

Patients with HR-positive, HER2-negative breast cancer experienced significant benefit when treated with neoadjuvant chemotherapy with intense dose-dense epirubicin, paclitaxel, and cyclophosphamide.

A significant improvement in overall survival was observed with the addition of hepatic arterial infusion chemotherapy to oxaliplatin, fluorouracil, and leucovorin compared with transarterial chemoembolization in patients with unresectable hepatocellular carcinoma.

Abemaciclib in combination with tamoxifen led to an improvement in overall survival compared with abemaciclib alone in patients with hormone receptor–positive, HER2-negative metastatic breast cancer. Notably, the benefit of the combination was observed across all subgroups in the study, according to findings from the final OS analysis of the nextMONARCH trial presented during the 2020 European Society of Medical Oncology Virtual Congress.
