Indication: Relapsed or refractory diffuse large B-cell lymphoma (DLBCL)

Phase: I/II

Summary: A multicentre, open-label study to evaluate the safety, efficacy, tolerability and pharmacokinetics of COLUMVI® (glofitamab) as a single agent in patients with relapsed/refractory B-cell non-Hodgkin's lymphoma (n=468).

The Swiss approval of COLUMVI® (glofitamab) is based on the results of the single-arm, pivotal phase II study extension in patients with relapsed or refractory diffuse large B-cell lymphoma who have previously received at least two lines of systemic therapy, including an anti-CD20 antibody and an anthracycline (n=145).

The following efficacy data refer to the subgroup of patients who were pretreated with CD19-targeted CAR-T cell therapy (n=47/145), of whom there were 34 with DLBCL NOS, 6 with tFL, 4 with HGBCL and 3 with PMBCL. 88.5% of patients were already refractory during CAR-T therapy.

After a median follow-up time of 12.6 months, the overall response rate was 55.3% (n=26/47) and the proportion of patients with complete response was 40.4% (n=19/47). The remissions (complete or partial) were achieved after a short time: median after two treatment cycles (42 days). Complete remissions continued even after the end of the time-limited therapy: median for 14.4 months.

The most common adverse event in the 145 patients was cytokine release syndrome (CRS, 63%), which was generally of low severity (grade 3–4: 4%). Other common adverse events (≥ 20%) were neutropenia, anaemia, thrombocytopenia and skin rash.

Results were published in Dickinson et al., Glofitamab for Relapsed or Refractory Diffuse Large B-Cell Lymphoma. N Engl J Med. 2022 Dec 15;387(24):2220-2231.
