MAVERICK trial data challenges prophylactic cranial irradiation in SCLC

Presented at WCLC 2026 in Seoul, the Phase III MAVERICK trial in limited or extensive stage small cell lung cancer (SCLC) showed no difference in preliminary overall survival between MRI surveillance alone versus MRI plus prophylactic cranial irradiation (PCI), with better cognitive failure-free survival favoring the MRI-alone arm. Looking ahead, potential FDA approvals in Q4 2026 include a first-in-class B7H3-targeted ADC for SCLC and a PD-1 x VEGF bispecific antibody for non-small-cell lung cancer (NSCLC).

FDA approves camizestrant for ESR1-mutant HR+ metastatic breast cancer; KOLs weigh ctDNA-guided switching

Community oncologists are digesting the FDA approval of camizestrant (Etcamah) for HR-positive metastatic breast cancer with an emergent ESR1 mutation detected in ctDNA before radiographic progression - the first approval built on treating a resistance mutation ahead of imaging progression (SERENA-6). Separately, results of the ELEVATE combination study of elacestrant plus everolimus in ER-positive, HER2-negative previously treated advanced breast cancer were published in Clinical Cancer Research.

New CRC Trial Opens; Early GPC3 CAR-T Data Published

Phase 1 results for the investigational GPC3-targeted CAR-T therapy TAK-102 in GPC3+ solid tumors (72.7% HCC) showed manageable safety with no DLTs, but limited efficacy, with a disease control rate of 45.5% consisting of stable disease. Separately, the new NEST-3 trial is now open in the US, evaluating neoadjuvant immunotherapy (BOT/BAL) for patients with mismatch repair proficient high-risk stage II/III colorectal cancer.

NECTIN4 Expression Linked to Enfortumab Vedotin Response

A re-analysis of the pivotal EV-301 trial data shows higher NECTIN4 expression was associated with improved response to enfortumab vedotin (ORR 45.8% vs 20.0%), a finding now undergoing prospective validation in the EVOKE trial. In prostate cancer, a Pan Prostate Cancer Group analysis of 959 genomes identified eight mutational footprints explaining 85% of cases, with four footprints associated with shorter time to metastasis. Discussions also center on the optimal sequencing of ¹⁷⁷Lu-PSMA-617 (Pluvicto) earlier in the treatment pathway and the limitations of PSMA PET/CT, which can miss microscopic nodal metastases despite its high accuracy.

New Myeloma Trial Tests MRD-Guided ASCT De-escalation

A new randomized controlled trial from CoMMitTrials is evaluating an MRD-guided approach in newly diagnosed multiple myeloma, testing time-limited bispecific antibody therapy for MRD-positive patients and de-escalation of ASCT for MRD-negative patients after quad induction. In Waldenström Macroglobulinemia, a discrete choice experiment with 1455 patients found that response duration and temporary toxicity most influence patient treatment preferences. Additionally, sales projections for 2025 place Darzalex as the second highest-selling oncology drug worldwide.

Early XmAb18968 data in AML/T-ALL; PRC2 inhibitor discontinued

A phase 1 study of the investigational CD38xCD3 bispecific T-cell engager XmAb18968 in relapsed/refractory AML and T-ALL showed early activity, including MRD-negative remissions, with no grade ≥3 CRS or neurotoxicity. Separately, development of the investigational PRC2 inhibitor pociredir was discontinued following an FDA class-wide risk re-assessment related to secondary hematologic malignancies. Other new data includes a SEER analysis of MPN epidemiology and a retrospective comparison of conditioning regimens for autologous stem cell transplant in Primary CNS Lymphoma.
