Data from the open-label phase 3 HOPE-B trial (NCT03569891) demonstrate that the treatment of patients with hemophilia B with etranacogene dezaparvovec (Hemgenix; CSL Behring) is superior to prophylactic factor IX treatment on annualized bleeding rate, with a favorable safety profile.

2. Bellicum Walks Away From GoCAR-T Cell Clinical Trials in Prostate Cancer, Solid Tumors

Another serious adverse event (AE) and dose-limiting toxicity is the latest blow to Bellicum Pharmaceuticals, who accounced it would halt progress on its clinical trials for its 2 GoCAR-T cell therapy candidates, BPX-601 and BPX-603. The latest in what has been a few rocky years for the biotech, this news has the company considering "strategic alternatives" for its path forward.

3. Robert J. Hopkin, MD, on Assessing ST-920 for Fabry Disease

The associate professor of clinical pediatrics at Cincinnati Children's Hospital Medical Center discussed Sangamo Therapeutics’ gene therapy, ST-920, and the phase 2 STAAR clinical trial. In addition, Hopkin discussed preliminary findings from kidney biopsies, the potential implications for patients if ST-920 is approved, and future plans for further research for the gene therapy.

4. JW Therapeutics Announces New Phase 2 Trial of Relma-Cel in Large B-cell Lymphoma

An open-label, prospective, single-arm phase 2 clinical trial (NCT05590221) of relmacabtagene autoleucel injection (relma-cel; JW Therapeutics) has been initiated in China, according to an announcement. The trial is aimed at assessing the autologous anti-CD19 CAR-T cell immunotherapy in a population of 20 individuals with high-risk large B-cell lymphoma (LBCL) as the first-line treatment and first patient infusion.

5. LHON Gene Therapy Continues to Show Efficacy and Safety at 3 Years Post Treatment

GenSight Biologics’ lenadogene nolparvovec (Lumevoq; GS010), an investigational adeno-associated viral (AAV) vector-based gene therapy being evaluated for the treatment of Leber hereditary optic neuropathy (LHON) in the phase 3 REFLECT clinical trial (NCT03293524), has demonstrated sustained efficacy and safety in 3-year follow-up data, with the best outcomes in patients who received bilateral treatment.
