In patients with locally advanced or metastatic urothelial carcinoma, atezolizumab and chemotherapy improved median progression-free survival by 1.9 months compared with placebo and chemotherapy. However, no overall survival benefit was seen, according to results of the phase III IMvigor130 trial presented at the 2019 ESMO Congress.

In the phase III PROfound trial, olaparib improved radiographic progression-free survival compared to either abiraterone acetate or enzalutamide in men with heavily pretreated metastatic castration-resistant prostate cancer, who had homologous recombination repair gene alterations, according to findings presented at the 2019 ESMO Congress.

Strong objective responses rates were seen in the phase I/II LIBRETTO trial, which studied RET inhibition with selpercatinib in patients with&nbsp;<em>RET</em>-mutant medullary thyroid cancer and for those with other&nbsp;<em>RET</em>&nbsp;fusion-positive thyroid cancer. The registrational findings were recently presented at ESMO Congress 2019.

Three clinical trials presented at the 2019 ESMO Congress show that the tropomyosin receptor kinase&nbsp;inhibitor larotrectinib continues to show anti-tumor activity, including long-lasting objective responses and low toxicity, according to results from an integrated analysis.

Results from the phase III MONARCH 2 trial showed that the addition of the CDK4/6 inhibitor abemaciclib to fulvestrant improved overall survival by 9.4 months compared with fulvestrant and placebo in patients with hormone receptor&ndash;positive, HER2-negative advanced breast cancer who progressed on prior endocrine therapy, according to data presented at the 2019 ESMO Congress.

A subgroup of patients with triple-negative breast cancer who had immune cell PD-L1 expression, by the SP142 immunohistochemistry assay had responses to atezolizumab and nab-paclitaxel, regardless of whether they had primary or metastatic disease, according to an exploratory biomarker substudy of IMpassion130.

Patients with advanced hormone receptor&ndash;positive, HER2-positive breast cancer had improved progression-free survival when receiving the CDK4/6 inhibitor abemaciclib and endocrine therapy with trastuzumab compared with trastuzumab and chemotherapy, according to findings from the randomized phase II monarcHER trial.¹

Frontline atezolizumab plus&nbsp;carboplatin plus etoposide has shown an improvement in overall survival over&nbsp;placebo plus CP/ET in&nbsp;the treatment of patients with extensive-stage small cell lung cancer, according to updated results from the phase III IMpower133 trial.

Ribociclib with fulvestrant resulted in a clinically significant overall survival benefit compared with placebo in postmenopausal patients with hormone receptor&ndash;positive, HER2-negative advanced breast cancer, according to findings from the phase III MONALEESA-3 trial presented at the 2019 ESMO Congress.
