ASCO Annual Meeting

Ghassan K. Abou-Alfa, MD, discusses the efficacy of ivosidenib in IDH1-mutant cholangiocarcinoma based on the results of the phase 3 ClarIDHy study.

Jennifer Litton, MD, highlights responses to talazoparib seen in patients with BRCA1/2-positive, early triple-negative breast cancer.

Ibrutinib plus venetoclax produced a complete response and complete response with incomplete bone marrow recovery rate of 56% in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma.

Cetuximab added to mFOLFOXIRI induced superior depth of response than mFOLFOXIRI plus bevacizumab in treatment-naïve patients with RAS wild-type metastatic colorectal cancer.

The novel BCL-2 inhibitor lisaftoclax elicited encouraging responses with acceptable tolerability in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma and other hematologic cancers.

The chemotherapy regimen of FOLFOXIRI plus bevacizumab was found to be preferred in terms of antitumor activity compared with FOLFOXIRI plus cetuximab in patients with RAS wild-type, BRAF V600E–mutant metastatic colorectal cancer.

The combination of pertuzumab and trastuzumab elicited a 37% disease control in patients with ERBB2/ERBB3-expressed, mutated, or -amplified uterine cancer.

The antibody-drug conjugate sacituzumab govitecan retained benefit in progression-free survival, overall survival, and objective response rate over physician’s choice of therapy, regardless of the chemotherapy agent used.

The frontline combination of pembrolizumab plus axitinib continued to show a survival benefit over single-agent sunitinib in patients with renal cell carcinoma.

Treatment with intra-tumoral SD-101 in combination with pembrolizumab and paclitaxel resulted in a non-statistically significant increase in estimated pathological complete response rates in patients with high-risk, HER2-negative stage II/III breast cancer across 3 HER2-negative biomarker signature groups.

Although prolonged treatment with bevacizumab for up to 30 months is feasible with consistent safety data for patients with primary epithelial ovarian, fallopian tube, or peritoneal cancer, the regimen did not improve survival over the standard 15 month treatment regimen.

Mirvetuximab soravtansine in combination with bevacizumab yielded durable responses in patients with recurrent, platinum agnostic ovarian cancer, a population in need of more effective, non-platinum treatments.

Larotrectinib has demonstrated efficacious responses and disease control in patients with TRK fusion–positive central nervous system tumors.

Lenvatinib and pembrolizumab continued to yield meaningful and durable responses in patients with advanced melanoma who had progressed on previous PD-L1 inhibitor treatment.

Lifileucel has demonstrated promising long-term responses in patients with heavily pretreated advanced or metastatic melanoma who have progressed following PD-1 and PD-L1 inhibition.

Nivolumab monotherapy, or in combination with ipilimumab, continued to demonstrate durable improvements in overall survival compared with ipilimumab alone in patients with previously untreated advanced melanoma.

Selpercatinib demonstrated evidence of preliminary efficacy and safety in pediatric patients with advanced RET-altered solid tumors.

Selpercatinib improved overall response rates in most patients with RET-mutated medullary thyroid cancer irrespective of prior systemic therapy.

Neoadjuvant nivolumab in combination with platinum-doublet chemotherapy significantly improved pathological complete response rates and had a greater depth of pathological response compared with chemotherapy alone in patients with resectable non–small cell lung cancer.

Adjuvant treatment with gefitinib delayed early relapse in patients with completely resected EGFR-mutant non–small cell lung cancer. However, the EGFR inhibitor did not significantly improve disease-free survival or overall survival compared with cisplatin/vinorelbine.

Patients with early-stage breast cancer who have ultralow risk disease indicated by a 70-gene signature demonstrated have an excellent survival prognosis regardless of clinical risk.

The combination of pyrotinib plus trastuzumab, docetaxel, and carboplatin (TCbH) significantly improved the total pathological complete response rate over TCbH alone in the neoadjuvant treatment of patients with HER2-positive breast cancer.

Pertuzumab plus trastuzumab, and nab-paclitaxel used as neoadjuvant therapy in patients with HER2-positive locally advanced breast cancer induced a pathologic complete response similar to that achieved with docetaxel, carboplatin, trastuzumab, and pertuzumab, with less treatment-related toxicities.

The autologous CAR T-cell product CART-ddBCMA was found to elicit a 100% objective response rate in patients with relapsed/refractory multiple myeloma, with deep and durable responses noted in those with poor prognostic factors.

A de-escalated course of neoadjuvant therapy of trastuzumab and pertuzumab with or without added weekly paclitaxel for only 12 weeks yielded high response rates and significant survival in patients with HER2-positive, hormone receptor–negative early breast cancer.

The addition of durvalumab to neoadjuvant anthracycline and taxane–based chemotherapy was found to significantly improve survival in patients with early triple-negative breast cancer.

Patients with stage III melanoma who progressed following placebo-based treatment in the first part of the phase 3 EORTC 1325/KEYNOTE-054 trial and crossed over to receive pembrolizumab post-recurrence derived a 38.8% overall response rate and a 32% overall 3-year progression-free survival rate.
