In a phase 1-2 trial, teclistamab, a bispecific antibody targeting CD3 on T-cell surfaces and B-cell maturation antigen on myeloma cells, showed durable responses in heavily pretreated patients with relapsed or refractory multiple myeloma. Daratumumab, a monoclonal antibody targeting CD38 protein, has shown survival benefit in patients with multiple myeloma.

Current second-line treatments for immune thrombocytopenia (ITP) require long-term administration. Ianalumab, a monoclonal antibody targeting B cells, is being assessed as a short-course second-line therapy in ITP.

Treatment of chronic lymphocytic leukemia (CLL) currently consists of two main approaches - continuous therapy with Bruton's tyrosine kinase inhibitors and fixed-duration regimens combining venetoclax with either CD20 antibodies or Bruton's tyrosine kinase inhibitors. Comparisons of these two therapeutic approaches are lacking.

Chronic granulomatous disease (CGD) is a severe monogenic immunodeficiency caused by damaging variants in genes required for microbicidal NADPH oxidase activity. Autosomal recessive p47phox-deficient CGD (p47-CGD) is predominantly caused by a two-nucleotide deletion in exon 2 (delGT) of NCF1. We developed PM359, an autologous CD34+ hematopoietic stem-cell therapy in which prime editing is used to correct delGT. Two participants received PM359 after myeloid conditioning with busulfan: neutrophils and platelets engrafted promptly in both patients. Adverse events were consistent with myeloid conditioning with busulfan. NADPH oxidase activity was observed in neutrophils within 1 month and was maintained for 6 months and 4 months as of the last follow-up visit in Participants 1 and 2, respectively. These results support further investigation of prime editing of CD34+ cells to treat p47-CGD. (Funded by Prime Medicine; ClinicalTrials.gov number, NCT06559176.).

Prophylactic treatment for hemophilia B necessitates lifelong, regular intravenous factor IX infusions. Gene therapy offers the possibility of a single-dose treatment that produces durable endogenous factor IX expression and disease control. Etranacogene dezaparvovec comprises an adeno-associated virus serotype 5 (AAV5) vector and the highly active Padua factor IX variant. The primary analysis of this study showed that etranacogene dezaparvovec reduced annualized bleeding rates and adverse events were mainly of low-grade severity. Final data from 5 years of follow-up are now available.

Patients with plasmacytomas that are noncontiguous with bone marrow (true extramedullary myeloma) are at high risk for disease progression or relapse. Phase 1 of the RedirecTT-1 study showed promising efficacy with dual-antigen targeting of myeloma with talquetamab (anti-G protein-coupled receptor family C group 5 member D) plus teclistamab (anti-B-cell maturation antigen) in patients with triple-class-exposed relapsed or refractory multiple myeloma, including those with true extramedullary myeloma.

Multidose human papillomavirus (HPV) vaccination is efficacious, yet the vaccine has been underused globally. Emerging data suggest that a single dose may provide protection. Whether a single dose of HPV vaccine would provide similar protection to two doses is uncertain.
