According to updated data from the phase 1b COSMIC-021 trial, treatment with cabozantinib and atezolizumab continued to demonstrate clinically meaningful activity in previously treated patients with locally advanced or metastatic castration-resistant prostate cancer, including those with high-risk clinical features.

Patients with previously treated HER2-positive metastatic breast cancer experienced a clinically meaningful and statistically significant improvement in progression-free survival with fam-trastuzumab deruxtecan-nxki vs standard of care trastuzumab emtansine in the DESTINY-Breast03 trial.

In patients with persistent, recurrent, or metastatic cervical cancer the addition of pembrolizumab to chemotherapy with or without bevacizumab significantly improved survival and response rates.

Compared with a placebo, adjuvant pembrolizumab led to a significant reduction in the risk of disease recurrence or death in patients with resected, high-risk stage II melanoma.

In previously untreated patients with metastatic or unresectable melanoma, the addition of relatlimab to nivolumab prolonged benefit beyond initial treatment and first progression and reduced the risk of progression or death after the next line of systemic therapy vs nivolumab alone.

Osimertinib (Tagrisso) plus bevacizumab does not produce a superior progression-free survival (PFS) benefit over osimertinib monotherapy in patients with non-squamous non-small cell lung cancer harboring an EGFR mutation. However, for patients who have a history of smoking or an exon 20 deletion, the combination may prove beneficial.

In a presentation at the 2021 ESMO Congress, researchers discussed how nivolumab plus ipilimumab showed superior efficacy results after a 5-year follow-up in comparison to single-agent sunitinib.

An exploratory subgroup analysis of the CheckMate 9ER trial discussed at the 2021 ESMO Congress showed significant benefits to progression-free survival for patients with renal cell carcinoma on nivolumab and cabozantinib regardless if they had prior nephrectomy.

Theodore W. Laetsch, MD, an attending physician at the Cancer Center at Children’s Hospital of Philadelphia, discusses the efficacy of larotrectinib in patients with TRK-fusion cancers.

Cabozantinib is a feasible perioperative treatment and induced responses in patients with intermediate and poor-risk metastatic renal cell carcinoma.

In Western patients with HER2-positive gastric/gastroesophageal junction cancer Fam-trastuzumab deruxtecan-nxki as a second-line treatment elicited a 38% confirmed objective response rate.

Pathological complete response rates and event-free survival in patients with treatment-naïve triple-negative breast cancer were improved with The addition of carboplatin to neoadjuvant paclitaxel followed by doxorubicin and cyclophosphamide.

In patients with metastatic or locally advanced urothelial carcinoma harboring FGFR alterations, erdafitinib (Balversa) in combination with cetrelimab displayed clinically meaningful responses.

Compared indirectly with real-world data of patients treated with standard of care, mobocertinib, a novel EGFR tyrosine kinase inhibitor, exhibited clinically meaningful activity in patients with non–small cell lung cancer who harbor EGFR exon 20 insertion mutations following frontline platinum-based chemotherapy.

Mobocertinib displayed a manageable safety profile across 40-mg, 120-mg, and 160-mg dose cohorts, leading to the determination of 160 mg as the maximum tolerated dose and recommended phase 2 dose for further study in Japanese patients with non–small cell lung cancer.

While the benefit is yet to be determined in those with favorable-risk disease, patients with advanced renal cell carcinoma experienced improvements in both progression-free and overall survival after being treated with first-line immunotherapy vs sunitinib.

High responses to single-agent dostarlimab-gxly were seen in patients with endometrial cancer who had a high tumor mutational burden, irrespective of mismatch repair or microsatellite stability status.

Compared with a placebo, darolutamide demonstrated a similar safety profile in men with nonmetastatic castration-resistant prostate cancer (nmCRPC) continuing androgen-deprivation therapy, with comparable adverse event onset and occurrence rates.

Darolutamide was statistically significantly associated with better episodic memory over enzaluamide, according to computerized cognitive assessment in men with metastatic castration-resistant prostate cancer.

Results from the DUNE trial of durvalumab added to tremelimumab in patients with advanced neuroendocrine tumors of gastroenteropancreatic and lung origins showed limited activity, according to a presentation held during the 2020 European Society of Medical Oncology Virtual Congress.

Frontline nivolumab plus chemotherapy induced a statistically significant survival benefit compared with chemotherapy alone in patients with newly diagnosed PD-L1–positive advanced gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma.

Preliminary activity was observed in an unselected group of patients with miscellaneous soft tissue sarcoma treated with trabectedin in combination with durvalumab in the phase 1b TRAMUNE trial. The results presented during the 2020 European Society of Medical Oncology Virtual Congress demonstrate the feasibility of utilizing this combination in soft tissue sarcoma.

Robert L. Coleman, MD, discusses the next steps for tisotumab vedotin following the presentation of findings from the phase 2 innovaTV 204/GOG-3023/ENGOT-cx6 study in patients with previously treated recurrent or metastatic cervical cancer.

Patients with advanced clear cell renal cell carcinoma treated with cabozantinib in combination with atezolizumab in the phase 1b COSMIC-021 study, had promising clinical activity, according to results from the study presented during the 2020 European Society of Medical Oncology Virtual Congress.

Prolonged progression-free survival was observed with pembrolizumab monotherapy in patients with selected rare sarcoma subtypes treated in the phase 2 AcSé basket study, according to a presentation during the 2020 European Society of Medical Oncology Virtual Congress.

In patients with newly diagnosed stage III/IV ovarian cancer, adding atezolizumab to a backbone combination of bevacizumab and chemotherapy did not improve progression-free survival, missing the primary end point of the phase 3 IMagyn050/GOG 3015/ENGOT-OV39 trial presented during the virtual 2020 European Society of Medical Oncology Congress.

In patients with early-stage EGFR mutated non–small cell lung cancer following complete tumor resection, treatment with osimertinib reduced the risk for central nervous system death or progression by 82%, findings presented during the EMSO Virtual Congress 2020.

Patients with endocrine-sensitive hormone receptor–positive, HER2-negative metastatic breast cancer, treated with Frontline fulvestrant in combination with palbociclib experienced improvement in progression-free survival at 1 year compared with fulvestrant and placebo alone, achieving the primary end point of the phase 2 FLIPPER trial.

Larotrectinib as treatment of patients with TRK fusion-positive thyroid cancer had rapid and durable disease control, with the highest response rates observed in the differentiated thyroid cancer population.

The use of molecularly-directed frontline therapy enriched responses in patients with metastatic clear cell renal cell carcinoma, demonstrating clinical evidence to support further use, according to findings from the noncomparative, phase 2, biomarker-driven BIONIKK trial.
