Material Changes and Developments
- EMA Validation: The EMA has validated the MAA for momelotinib based on data from key Phase III trials, specifically the pivotal MOMENTUM trial.
- Trial Success: The MOMENTUM trial met all primary and key secondary efficacy endpoints, including Total Symptom Score (TSS) reduction, Transfusion Independence (TI) rate, and Splenic Response Rate (SRR).
- Regulatory Timeline: A regulatory action by the EMA's Committee for Medicinal Products for Human Use (CHMP) is anticipated by year-end 2023.
- US Status: A New Drug Application (NDA) is under review by the US FDA, with a Prescription Drug User Fee Act action date set for June 16, 2023.
Outlook, Risks, and Management Commentary
Management Commentary: GSK highlights momelotinib's differentiated mechanism of action, inhibiting JAK1, JAK2, and ACVR1 pathways. If approved, it would be the only medicine addressing key manifestations of myelofibrosis, including anaemia, symptoms, and splenomegaly. Updated 48-week data from the MOMENTUM trial is scheduled for presentation at the American Society of Hematology (ASH) Annual Meeting in December 2022.
Risks and Contingencies: The filing includes a cautionary statement regarding forward-looking statements. Actual results may differ materially due to risks described in the 2021 Form 20-F, Q3 2022 results, and potential impacts of the COVID-19 pandemic. Approval by regulators is not guaranteed.
