Frontline fulvestrant in combination with palbociclib demonstrated an improvement in progression-free survival at 1 year compared with fulvestrant and placebo alone in patients with endocrine-sensitive hormone receptor-positive, HER2-negative metastatic breast cancer, which met the primary end point of the phase 2 FLIPPER trial.

Osimertinib reduced the risk for central nervous system death or progression by 82% in patients with early-stage EGFR mutated non–small cell lung cancer following complete tumor resection.

Frontline pembrolizumab plus chemotherapy significantly improved overall survival, progression-free survival, and objective response rates compared with chemotherapy alone in patients with locally advanced unresectable or metastatic esophageal cancer.

Treatment with AMG 160 showed a manageable safety profile with preliminary efficacy in patients with metastatic castration-resistant prostate cancer.

The addition of tucatinib to trastuzumab and capecitabine in patients with HER2-positive metastatic breast cancer with and without brain metastases resulted in statistically significant and clinically meaningful improvements in progression-free and overall survival.

Lenvatinib plus pembrolizumab showed early antitumor activity and tolerability in previously treated patients with advanced solid tumors.

Ipatasertib combined with abiraterone acetate plus prednisone led to a significantly superior radiographic progression-free survival and antitumor activity compared with placebo plus abiraterone/prednisone in patients with metastatic castration-resistant prostate cancer with PTEN loss.

Long-term follow-up of patients with locally advanced or metastatic urothelial carcinoma treated with enfortumab vedotin monotherapy showed encouraging results, with half of patients still alive at 12 months and approximately one-third alive at 18 months.

BLU-945, an investigational precision therapy, elicited robust antitumor activity in multiple preclinical models of triple-mutated EGFR-positive non–small cell lung cancer .

Zarnie Lwin, MBBS, FRACP, discusses the results of the LEAP-005 trial in advanced solid tumors.

Stephen Johnston, MA, PhD, FRCP, discusses the results of the phase 3 monarchE study examining the addition of abemaciclib to endocrine therapy in patients with high-risk early hormone receptor–positive, HER2-negative breast cancer.

Regorafenib extended progression-free survival at 24 weeks compared with placebo for patients with Ewing sarcoma in the phase 2 REGOBONE study. However, the oral multi-kinase inhibitor failed to meet the study’s primary endpoint of non-progression at 8 weeks.

Olaparib induced a significantly longer duration of overall survival, compared with enzalutamide or abiraterone plus prednisone, in men with metastatic castration-resistant prostate cancer who had tumors with at least 1 alteration in BRCA1, BRCA2, or ATM and whose disease had progressed during previous treatment with a next-generation hormonal agent.

Potent and durable clinical activity was shown with pralsetinib as treatment of patients with RET-mutant advanced medullary thyroid cancer, regardless of the line of therapy.

The combination of amivantamab and lazertinib demonstrated high response rates and was well tolerated in treatment-naïve and osimertinib-resistant patients with advanced EGFR-mutant non–small cell lung cancer.

Dual inhibition of both VEGFR and EGFR with the combination of apatinib and gefitinib in the first-line treatment of patients with advanced EGFR-mutant non–small cell lung cancer demonstrated superior progression-free survival.

An acceptable safety profile coupled with pharmacokinetic and pharmacodynamic data for the DART molecule MGD019 were reported during the European Society for Medical Oncology Virtual Congress 2020 from results of a first-in-human study.

The combination of osimertinib and bevacizumab did not prolong progression-free survival in patients with advanced adenocarcinoma who had EGFR T790M mutations compared with osimertinib alone

The investigational drug sotorasib demonstrated promising antitumor activity in patients with non-small cell lung cancer that harbor the KRAS p.G12C mutation, an aberration for which no targeted treatment has yet been approved.

Overall survival benefits of frontline maintenance treatment with avelumab in patients with advanced urothelial cancer were found to be positively associated with biomarkers of immune activity and negativity linked with biomarkers of tumor homeostasis and chronic inflammation.

Quality of life according to patient-reported outcomes was not reduced despite treatment toxicities in those with ovarian, primary peritoneal, or fallopian tube cancer treated with niraparib versus placebo in the PRIMA/ENGOT-OV26/GOG-3012 trial.

The addition of abemaciclib to endocrine therapy led to a significant reduction in the risk of invasive disease versus endocrine therapy alone in patients with high-risk early hormone receptor–positive, HER2-negative breast cancer.

Post-operative radiotherapy was linked with a nonstatistically significant increase in disease-free survival in patients with completely resected stage IIIAN2 non–small cell lung cancer and thus cannot be recommended as a standard of care for this population.

Neoadjuvant chemotherapy with intense dose-dense epirubicin, paclitaxel, and cyclophosphamide demonstrated significant benefit in the treatment of patients with HR+/HER2- breast cancer.

The addition of neoadjuvant atezolizumab to nab-paclitaxel plus doxorubicin and cyclophosphamide significantly improved pathologic complete responses in patients with stage 2 or stage 3 triple-negative breast cancer, compared with placebo plus chemotherapy.

Overall survival was significantly improved in patients who received hepatic arterial infusion chemotherapy with oxaliplatin, fluorouracil, and leucovorin compared with transarterial chemoembolization.
