A higher incidence of somatically acquired genetic alterations, including damaging mutations in ZMYM3 leading to genomic instability, as well as deletions in MAP3K7, BNIP3L, RB1, and NEIL3, and gain of MYC, may lead to more aggressive prostate cancer in Black/African American men.

I-Mab Biopharma and ABL Bio, Inc set their sights on adding the bispecific antibody, TJ-CD4B, to the expanding armamentarium for patients with various types of advanced and metastatic solid cancers.

The development of novel therapies aimed at tumors with RET alterations in non-small cell lung cancer and thyroid cancers sets the stage for a future tumor-agnostic role for this molecularly targeted approach.

Samuel Ahuno discusses bringing precision medicine in cancer care to Ghana.

Dual inhibition of the MAPK pathway using the BRAF and MEK inhibitors dabrafenib and trametinib, respectively, resulted in durable clinical benefit for patients with BRAF V600E mutant low- and high-grade glioma.

Selpercatinib demonstrated a favorable safety profile, characterized by low-grade treatment-emergent adverse effects, manageable early onset toxicity, and low rates of treatment discontinuation, in patients with RET-altered advanced solid tumors.

Paz Polak, PhD, discusses research that evaluated cancer genomes in Ghana through the use of liquid biopsies.

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.

Conflicting results regarding the benefit of adjuvant CDK4/6 inhibition in early-stage hormone receptor–positive, HER2-negative breast cancer have prompted many questions regarding patient selection and treatment duration, which many hope will be answered with ongoing biomarker research.

The FDA has approved a new biweekly dosing regimen of 500 mg/m2 as a 120-minute intravenous infusion for cetuximab (Erbitux) for patients with KRAS wild-type, EGFR-expressing colorectal cancer or squamous cell carcinoma of the head and neck.

Tanya Dorff, MD, discusses how the FDA approvals of olaparib and rucaparib have paved the way for additional research with PARP inhibitors in metastatic castration-resistant prostate cancer.

Ulrich Steidl, MD, PhD, discusses translational research efforts that have been made with targeting leukemia stem cells and ongoing clinical trials that are examining novel therapeutic targets in myeloid malignancies and beyond.

The RET inhibitor TPX-0046 demonstrated encouraging preliminary activity, which included objective responses, and an acceptable toxicity profile when used in patients with RET-driven advanced solid tumors.

Thomas C. Krivak, MD, discusses the significance of HRD in ovarian cancer, approved and prospective HRD tests, and considerations for genomic testing in this population.
