The FDA has set a Prescription Drug User Fee Act (“PDUFA”) target date of May 21, 2021.
“The FDA’s acceptance of our BLA and granting of priority review for Lonca is a tremendous accomplishment that brings ADC Therapeutics one step closer to being able to offer patients with relapsed or refractory DLBCL a greatly needed new treatment option in 2021,” said Chris Martin, Chief Executive Officer of ADC Therapeutics. “We look forward to working with the FDA during its review of our BLA submission for Lonca. Our organization remains focused on robust planning for a successful launch next year.”
The BLA submission is based on data from LOTIS 2, the pivotal Phase 2 multi-center, open-label, single-arm clinical trial evaluating the efficacy and safety of Lonca in patients with relapsed or refractory DLBCL following two or more lines of prior therapy. In June 2020, the Company presented maturing data from LOTIS 2 at the virtual 25th Congress of the European Hematology Association. As of the April 6th cutoff date, Lonca demonstrated an overall response rate of 48.3% (70/145 patients) and a complete response rate of 24.1% (35/145 patients). The tolerability profile was manageable with the most common grade ≥3 treatment-emergent adverse events in ≥10% of patients being: neutropenia (25.5%) with low incidence of febrile neutropenia (3.4%), thrombocytopenia (17.9%), GGT increase (16.6%) and anaemia (10.3%).
Data from subgroup analyses of LOTIS 2 will be presented in a poster (abstract #1183) at the upcoming 62nd American Society for Hematology (ASH) Annual Meeting on Saturday, December 5, 2020.
