Gene therapy safety update amid confirmed tumors after Zolgensma
Novartis disclosed additional tumor reports in children treated with Zolgensma (onasemnogene abeparvovec), confirming nine total cases since approval in 2019, including seven newly disclosed reports. The company said two cases show evidence of vector DNA integration into patient DNA and noted the prescribing information already includes a theoretical tumorigenicity risk from AAV vector integration. The disclosure sharpens ongoing post-marketing scrutiny of AAV-based gene therapies, with implications for long-term monitoring, patient counseling, and how regulators and sponsors manage rare-but-serious adverse events when integration signals are detected.

Duchenne gene therapy shows multi-year cardiac safety in pooled trials
A pooled analysis of four clinical trials of delandistrogene moxeparvovec in predominantly young, ambulatory patients with Duchenne muscular dystrophy reported a manageable cardiac safety profile over up to five years of follow-up. The dataset supports continued confidence in longer-term monitoring expectations for gene therapy recipients, where cardiac outcomes are a central concern in DMD. While efficacy endpoints are not detailed in the provided brief, the emphasis on cardiac safety duration reinforces how sponsors are validating systemic risks beyond early post-infusion periods.

Reproductive-to-cancer signal: circulating SDF4 emerges as an SLE biomarker candidate
Researchers reported that stromal cell–derived factor 4 (SDF4) could help diagnose systemic lupus erythematosus and potentially track disease severity. In BMC Immunology analyses, SDF4 levels were higher in SLE samples than in healthy controls, and serum SDF4 showed strong discrimination with an area under the curve of 0.954 in distinguishing SLE from controls. The results position SDF4 as a biomarker that could refine diagnostic and severity assessment workflows, though the study’s clinical utility will depend on external validation, assay standardization, and performance against existing serologic markers.

Cancer therapeutics safety signals: palbociclib linked to rare autoimmune neuropathy mimic
Clinicians described a metastatic breast cancer case in which palbociclib treatment preceded a rare chronic immune-mediated polyradiculoneuropathy with anti-neurofascin antibodies, mimicking CIDP. The report underscores how immune-targeted adverse events can present with overlapping phenotypes, complicating diagnosis and treatment decisions for patients on CDK4/6 inhibitors. For practice, the key takeaway is heightened awareness and early neurology evaluation when new neuropathy symptoms emerge during therapy, as well as careful immune workup to distinguish autoimmune syndromes from treatment-related or paraneoplastic causes.

Cell therapy delivery strategy expands: intraperitoneal CAR-T outperforms IV in preclinical solid tumor models
In solid tumor preclinical experiments, intraperitoneal (i.p.) CAR-T administration produced stronger antitumor effects than standard intravenous (i.v.) delivery. The study reported increased CAR-T persistence both systemically and within the tumor, with improved endpoint measures of tumor control and altered exhaustion-associated receptor expression. The work also used PET-CT tracking with radiolabeled CAR-T cells to compare early biodistribution, supporting the conclusion that local delivery routes can overcome delivery barriers that limit CAR-T effectiveness in solid tumors.
