The tumor-infiltrating lymphocyte therapy lifileucel was found to elicit durable responses in patients with advanced melanoma who were previously treated with an immune checkpoint inhibitor.

The addition of ipilimumab to nivolumab as an adjuvant treatment failed to improve relapse-free survival in the intent-to-treat and PD-L1 of less than 1% populations compared with nivolumab alone in patients with resected stage IIIB to D/IV melanoma.

Nivolumab plus ipilimumab was found to induce significant antitumor activity when administered to patients with metastatic castration-resistant prostate cancer and immunogenic signature.

Nivolumab in combination with paclitaxel showed clinical activity and a manageable safety profile when used as second-line therapy for patients with Epstein-Barr virus–related, microsatellite instability–high/mismatch repair deficient or PD-L1–positive advanced gastric cancer.

Zenocutuzumab has been shown to block the growth and cause the death of NRG1 fusion–positive cell lines, and to induce tumor shrinkage and durable tumor regression in multiple cancers when used in NRG1 fusion–positive patient-derived xenografts.

Trastuzumab deruxtecan has not only demonstrated efficacy as a potential anti-HER2 therapeutic option for patients with HER2-amplified gastric cancers, but has also shown promise in those with HER2 moderate-, low-, and non-expressing disease.

Abdulraheem Yacoub, MD, discusses the rationale behind examining parsaclisib following suboptimal response to ruxolitinib in patients with myelofibrosis.

Xiuning Le, MD, PhD, discusses the safety findings of the phase 2 ZENITH20-5 study with poziotinib in patients with EGFR- or HER2 exon 20–positive non–small cell lung cancer.

Benjamin Besse, MD, discusses the results of an ad-hoc safety analysis of the phase 1/2 LIBRETTO-001 trial, which examined the use of selpercatinib in patients with RET-altered advanced medullary thyroid cancer and non–small cell lung cancer.

Thomas Urban Marron, MD, PhD, discusses primary objectives of a study examining the use of an adjuvant personalized neoantigen peptide vaccine in several malignancies.

The combination of copanlisib and rituximab was associated with a 48% reduction in the risk of disease progression or death compared with rituximab plus placebo in patients with relapsed indolent non-Hodgkin lymphoma.

Maintaining a healthy lifestyle was found to reduce the likelihood of developing metastatic disease or dying of prostate cancer among men who had a high genetic risk.

The presence of pathogenic or likely pathogenic germline variants in cancer predisposition genes, which were identified in approximately 1 in 5 patients with neuroblastoma and were mostly inherited, was shown to correlate with worse event-free survival and overall survival vs the absence of germline variants.

The CDK9 inhibitor voruciclib demonstrated early activity as a single agent in KRAS-mutant cancer cell lines, and synergistically inhibited growth of KRAS-mutant cancers when used in combination with sotorasib and adagrasib in preclinical models.

Tebentafusp (IMCgp100) resulted in a highly significant and clinically meaningful improvement in overall survival when given as a frontline treatment in patients with metastatic uveal melanoma.

Neoadjuvant treatment with nivolumab combined with chemotherapy led to a significant improvement in pathologic complete response compared with chemotherapy alone in patients with resectable non–small cell lung cancer.

Justin Moyers, MD, discusses real-world data and sociodemographic factors from an early analysis of the National Cancer Database associated with the treatment of adjuvant immunotherapy in stage III melanoma.

Patients with breast cancer who harbor multiple PIK3A-mutant tumors achieved a higher clinical benefit from PI3Kα inhibition compared with single mutant tumors according to response analysis data from the SANDPIPER trial.

The neoadjuvant combination of nivolumab and ipilimumab continues to demonstrate a benefit in RFS compared with the combination given in the adjuvant setting in patients with stage III macroscopic melanoma.

Sheila Figel, PhD, a neuro-oncologic scientist with Roswell Park Comprehensive Cancer Center, discusses preclinical research with canonical and noncanonical that are displayed on the surface of cancer cells.

The combination of nivolumab and ipilimumab provided similar clinical benefit to that of chemotherapy when given as a frontline treatment for patients with advanced non–small cell lung cancer who had stable and treated brain metastases at baseline.

Tiragolumab in combination with atezolizumab (Tecentriq) demonstrated early clinical activity and was found to be well tolerated in patients with advanced solid tumors, including those with metastatic non–small cell lung cancer who were PD-L1 positive and had not received prior checkpoint inhibition.

Leora Horn, MD, MSc, discusses data from an updated analysis of the phase 3 IMpower133 trial, which examined the first-line combination of atezolizumab (Tecentriq), carboplatin, and etoposide in small cell lung cancer.

The HER2-selective TKI tucatinib (Tukysa) demonstrated potent antitumor activity alone and in combination with ado-trastuzumab emtansine (T-DM1; Kadcyla) in HER2-overexpressing breast cancer cell lines and xenograft models.

The oral modified dysfunctional tyrosine SM-88 has demonstrated antitumor activity and appears to broadly effect the immune dynamics of the tumor microenvironment, according to early data from 2 xenograft studies.

Circulating tumor DNA clearance of EGFR mutation may be predictive of prolonged progression-free survival for patients with EGFR-mutant, MET-amplified non–small cell lung cancer with detectable ctDNA at baseline.

Timothy Cragin Wang, MD, discusses the lack of response to checkpoint inhibitors in colorectal cancer.

The FDA is presently spearheading several initiatives in light of COVID-19 aimed at refining the role of RWD in cancer care to guide clinical trial development, procure answers to pressing clinical questions, and support regulatory decisions for in vitro diagnostics.
