Bruton tyrosine kinase (BTK) enzyme inhibitors used to treat B-cell cancers, including chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma, also produce resistance by causing mutations in the protein. Now, a study on the BTK degrader NX-2127 showed the compound could be effective in eliminating BTK regardless of its mutations.
NX-2127 showcased early efficacy in the form of responses with an acceptable toxicity profile in patients with relapsed or refractory B-cell malignancies, according to data from the ongoing phase 1 NX-2127-001 trial.
The FDA has placed a partial clinical hold on the phase 1 NX-2127-001 trial investigating the novel BTK degrader NX-2127 in patients with relapsed/refractory B-cell malignancies.
