"We are very pleased with the continued strong momentum of our U.S. launch of OGSIVEO for adults with desmoid tumors. In the second quarter, we also completed the submission of our NDA for mirdametinib in NF1-PN, which positions us to potentially have our second medicine available for patients in 2025," said Saqib Islam, Chief Executive Officer of SpringWorks. "Our focus for the second half of 2024 will be to drive broader adoption of OGSIVEO, to advance our commercial preparations for the launch of mirdametinib for children and adults with NF1-PN, to continue advancing OGSIVEO and mirdametinib through the European regulatory process, and to progress our emerging portfolio for patient populations with high unmet needs."
Recent Business Highlights and Upcoming Milestones
OGSIVEO (Nirogacestat)
Strong commercial execution of the OGSIVEO launch, with net product revenue of $40.2 million in the second quarter of 2024.
In May 2024, SpringWorks introduced OGSIVEO 150 mg and 100 mg tablets in blister packaging, which was developed to enhance patient convenience with OGSIVEO.
A Marketing Authorization Application (MAA) for nirogacestat for the treatment of adult patients with desmoid tumors is under review with the European Medicines Agency (EMA).
Additional data from the Phase 3 DeFi trial of nirogacestat in adults with desmoid tumors highlighting consistent safety and efficacy across subgroups of high-risk patient populations and updated ovarian toxicity resolution data supporting the transience of ovarian toxicity were presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.
SpringWorks expects to present long-term follow-up data from the Phase 3 DeFi trial at a medical conference in the second half of 2024.
SpringWorks expects to report initial data from the Phase 2 trial evaluating nirogacestat as a monotherapy in patients with recurrent ovarian granulosa cell tumors in the second half of 2024.
SpringWorks is continuing to support several industry and academic collaborator studies evaluating nirogacestat as part of B-cell maturation antigen (BCMA) combination therapy regimens across treatment lines in patients with multiple myeloma.
Mirdametinib
SpringWorks completed the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for mirdametinib for the treatment of children and adults with NF1-PN.
The Company expects to complete the submission of an MAA for mirdametinib for the treatment of children and adults with NF1-PN in the European Union in the second half of 2024.
Data from the pediatric and adult cohorts of the Phase 2b ReNeu trial were presented in an oral presentation at the 2024 ASCO (Free ASCO Whitepaper) Annual Meeting and were also featured at the 2024 Global NF Conference and at the International Symposium on Pediatric Neuro-Oncology (ISPNO) 2024 meeting. Results showed robust objective response rates confirmed by blinded independent central review, deep responses, significant reductions in pain, improvement in other quality of life measures, and a manageable and tolerable safety profile were achieved across both the pediatric and adult cohorts. SpringWorks expects to publish the ReNeu trial results in a peer-reviewed journal in the second half of 2024.
A poster evaluating the dispersible tablet of mirdametinib in children with NF1-PN in the ReNeu trial was presented at the ISPNO 2024 meeting. Patients and caregivers reported high acceptability scores for ease of swallowing and willingness to take the dispersible tablet formulation, indicating that this formulation provides an acceptable option for children or adults with swallowing difficulties.
Initial data from the Phase 1/2 trial evaluating mirdametinib in patients with pediatric low-grade gliomas (pLGG) were presented at the ISPNO 2024 meeting. Results from 23 patients enrolled in the Phase 1 portion of the study suggested that mirdametinib, which has high blood brain barrier penetration, has encouraging clinical activity in patients with recurrent/progressive pLGG across a variety of MAPK pathway aberrations. The Phase 2 portion of the study is ongoing and recruiting patients.
Emerging Pipeline
A Phase 1b trial evaluating brimarafenib (BGB-3245) in adult patients with RAF mutant solid tumors is ongoing; additional data from the dose expansion portion of the study is expected to be presented in the first half of 2025. Brimarafenib is an investigational, selective RAF dimer inhibitor being developed by MapKure, LLC, a joint venture between SpringWorks and BeiGene, Ltd.
Patients continue to be enrolled in several combination therapy oncology programs: a Phase 1/2a study of brimarafenib and mirdametinib in MAPK mutant solid tumors, a Phase 1b trial of brimarafenib and Amgen’s EGFR inhibitor, panitumumab, in colorectal and pancreatic cancer patients with known MAPK pathway mutations, and a Phase 1b trial of mirdametinib with BeiGene’s RAF dimer inhibitor, lifirafenib, in adult patients with NRAS mutant solid tumors.
SpringWorks initiated a Phase 1a trial of SW-682, an investigational novel, oral, potent, and selective pan-TEAD inhibitor, in Hippo-mutant solid tumors in the second quarter of 2024.
General Corporate
In July, SpringWorks appointed Martin Mackay, Ph.D. to the Company’s Board of Directors. Dr. Mackay is a highly accomplished R&D executive with more than 30 years of pharmaceutical and biotech R&D experience, including leadership roles at Pfizer, AstraZeneca and Alexion.
Second Quarter 2024 Financial Results
Product Revenue: OGSIVEO net product revenue was $40.2 million in the second quarter of 2024.
Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $57.8 million for the second quarter of 2024, compared to $47.0 million for the comparable period of 2023. The increase in SG&A expense was primarily attributable to commercial activities supporting the U.S. launch of OGSIVEO, as well as commercial readiness activities to support the U.S. launch of mirdametinib, if approved.
Research and Development (R&D) Expenses: R&D expenses were $44.4 million for the second quarter of 2024, compared to $35.9 million for the comparable period of 2023. The increase in R&D expenses was primarily attributable to an increase in costs related to drug manufacturing, clinical trials, other research, consulting and professional services, and an increase in employee costs associated with headcount growth.
Net Loss Attributable to Common Stockholders: SpringWorks reported a net loss of $39.9 million, or $0.54 per share, for the second quarter of 2024. This compares to a net loss of $77.9 million, or $1.25 per share, for the comparable period of 2023.
