FDA gene therapy approval and pediatric voucher catalyst
FDA has approved Rocket Pharmaceuticals’ gene therapy Kresladi (marne-cel), targeting leukocyte adhesion deficiency type I, according to an FDA March approvals update from Rocket. The company said the treatment is its first BLA to pass through CBER this year and that it expects to launch by year-end. Alongside the approval, FDA issued a rare pediatric disease priority review voucher tied to the gene therapy. The voucher mechanism can accelerate review timelines for future therapies, which makes it a strategic lever for Rocket as it advances its platform and pipeline. Rocket also positioned the manufacturing and commercialization path as the next milestone after the CBER decision, with near-term execution focused on launch readiness and patient access planning.

Pivotal immunotherapy signals in solid tumors
A phase II GETNE-DUTHY study is advancing a new combination approach for advanced thyroid cancer using checkpoint blockade with durvalumab and tremelimumab. The trial is led by Capdevila, Hernando, and Molina-Cerillo, and evaluates whether the dual PD-(L)1 and CTLA-4 strategy can improve outcomes in a setting with limited durable options. Separately, researchers reported preclinical/clinical immunotherapy modulation tied to colorectal cancer, where circulating glycocholic acid (GCA) appears to influence response to immune checkpoint therapy. The work frames GCA as a potential biomarker or combination lever for improving immunotherapy efficacy. Together, the updates underscore a continuing focus on refining checkpoint inhibitor combinations and identifying actionable biology that could widen the proportion of patients who respond.

Epigenetic reactivation strategy in AML
Researchers at The Jackson Laboratory (JAX) reported that an epigenetic strategy can restore tumor suppressor activity in acute myeloid leukemia models. In a Science Translational Medicine paper, the team showed KDM4 inhibition can reactivate the tumor suppressor ZBTB7A, reducing leukemia burden in mice. The work used a combined FISHnCRISP workflow—fluorescence in situ hybridization plus flow cytometry with CRISPR editing—to identify ZBTB7A as silenced in AML cells and to map regulatory mechanisms. The data indicated AML cells carry a longer ZBTB7A regulatory tail that recruits ZFP36L2, while KDM4-mediated chromatin packaging further suppresses the gene. The authors emphasized the dual impact: restoring a gene-silencing axis rather than solely pursuing cytotoxicity, while maintaining largely preserved normal blood formation in the models.

Bioengineering platform for fast-acting covalent protein drugs
A Westlake University team disclosed a high-throughput engineering platform aimed at creating fast-acting covalent protein therapeutics. The approach, published in Science, describes a selection system designed to identify covalent binders with rapid functional effects. The platform—led by principal investigators Bobo Dang and Ting Zhou at Westlake Laboratory—targets a practical bottleneck in covalent biologics: scaling the design and screening of candidates efficiently while preserving the desired speed and specificity of covalent engagement. The report signals a push toward next-generation biologics that combine potency with temporal control, potentially expanding covalent chemistry use beyond traditional small-molecule settings.

Targeted nanomedicine aimed at overcoming colon cancer resistance
Researchers engineered an iRGD-PLGA nanocomplex designed to target colon cancer drug resistance. The platform combines iRGD tumor-targeting behavior with PLGA delivery chemistry and is positioned to address resistance and metastatic spread, which remain major constraints for effective treatment. The disclosure frames the strategy as a targeted nanomedicine approach intended to improve delivery to resistant tumor populations and enhance therapeutic effect when conventional regimens fail. The report adds to the growing set of nanoparticle-and-ligand designs aimed at directing payloads to difficult-to-treat tumor microenvironments.
