Nearly a full month ahead of the PDUFA date, ADC Therapeutics SA said Friday the FDA has granted accelerated approval for Zynlonta (loncastuximab tesirine), a CD19-targeted antibody-drug conjugate for the single-agent treatment of adults with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy. The approved indication includes the treatment of patients with diffuse large B-cell lymphoma not otherwise specified and those with DLBCL arising from low grade lymphoma and high grade B-cell lymphoma, which ADC's CEO Chris Martin said would be an important point of differentiation for the product.
