Momenta Pharmaceuticals, Inc. provided an update on the Company’s clinical trial activities and business operations in light of the COVID-19 pandemic. Momenta remains committed to its development programs, but recognizes the impact and risks imposed by COVID-19 on the global healthcare system. The Company is making all efforts to allow patients currently enrolled in its clinical studies to continue unimpeded and is in close contact with clinical sites to ensure patients have access to the investigational drugs. Momenta has also implemented additional measures to protect the health and safety of patients and healthcare professionals involved with its clinical studies, and to preserve the integrity of its clinical data. Nipocalimab (M281): a fully human anti-neonatal Fc receptor (FcRn) aglycosylated immunoglobulin G (IgG1) monoclonal antibody (mAb). Vivacity-MG is the Company’s Phase 2 clinical study of nipocalimab in generalized myasthenia gravis (gMG). As previously reported, this trial achieved target patient enrollment in February 2020. The Company currently remains on track to report topline data from this study in the third quarter of 2020. Unity, the Company’s global multi-center Phase 2 clinical study of nipocalimab in hemolytic disease of the fetus and newborn (HDFN), continues to enroll patients at sites where they can be safely accommodated. At this time, based on the life-threatening nature of HDFN, the Company does not intend to pause enrollment of the study but anticipates a slower pace of enrollment due to the overall global impact of COVID-19. The Company’s Energy Study, an adaptive Phase 2/3 clinical study of nipocalimab in warm autoimmune hemolytic anemia (wAIHA), has been activating sites globally. The Company will continue to activate sites but has temporarily suspended patient enrollment. M254 (hsIgG): a hypersialylated immunoglobulin designed as a high potency alternative for intravenous immunoglobulin (IVIg). M254 is currently being evaluated in Momenta’s multi-part Phase 1/2 study in idiopathic thrombocytopenic purpura (ITP). Momenta continues to enroll lower dose cohorts in Part B of the ongoing trial, however most of the sites have suspended enrollment due to the COVID-19 pandemic. As a result and in anticipation of slower enrollment, the Company may not be able to report interim data as planned for the second quarter of 2020. The ITP study Parts C and D, which are being evaluated in the context of emerging Part B data, will be delayed until Part B is complete and depending on then-prevailing conditions for clinical trials. The Company also expects that its planned Phase 2 study of M254 in chronic inflammatory demyelinating polyneuropathy (CIDP) will commence in 2021. Momenta is closely monitoring the evolving situation and expects to resume patient enrollment and initiate delayed studies when conditions permit.
