Recent Business Highlights and Upcoming Milestones

OGSIVEO^® (Nirogacestat)

• Strong execution in the first full quarter of launch, with net product revenue of $21.0 million in the first quarter of 2024.
• Received U.S. Food and Drug Administration (FDA) approval of a Supplemental New Drug Application (NDA) for OGSIVEO 150 mg and 100 mg tablets in new blister packaging, which have been developed to enhance patient convenience with OGSIVEO. The blister packs are expected to be on the market in mid-May 2024.
• Received validation from the European Medicines Agency (EMA) on a Marketing Authorization Application (MAA) for nirogacestat for the treatment of adult patients with desmoid tumors in February 2024.
• Additional data from the Phase 3 DeFi trial of nirogacestat in adults with desmoid tumors were accepted for presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. An abstract describing the onset and resolution of ovarian toxicity for desmoid tumor patients treated with nirogacestat was selected as an oral presentation to be delivered on May 31, 2024. Two additional sub-group analyses evaluating nirogacestat in desmoid tumor patients with poor prognostic factors and in those with adenomatous polyposis (APC) mutations will also be presented on June 1, 2024.  
• On track 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.
• 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

• Initiated rolling submission of an NDA to the FDA for mirdametinib for the treatment of children and adults with NF1-PN in March 2024. SpringWorks expects to complete the NDA submission in the second quarter of 2024 and expects to file an MAA with the EMA for mirdametinib for the treatment of children and adults with NF1-PN in the European Union the second half of 2024.
• Data from the pediatric and adult cohorts of the Phase 2b ReNeu trial were accepted for oral presentation as a rapid oral abstract at the 2024 ASCO Annual Meeting on June 3, 2024. SpringWorks also expects to publish the ReNeu trial results in a peer-reviewed journal in 2024.

Emerging Pipeline

• On track to present additional data from the dose expansion portion of the Phase 1b trial evaluating brimarafenib (BGB-3245) in adult patients with RAF mutant solid tumors in the second half of 2024. 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 the dose escalation phase of the SpringWorks-sponsored Phase 1/2a combination study of brimarafenib and mirdametinib.
• MapKure initiated a Phase 1b combination trial of brimarafenib with panitumumab, a monoclonal antibody targeting Epidermal Growth Factor Receptor in colorectal and pancreatic cancer patients with known MAPK pathway mutations; patient dosing is currently underway.
• Dose expansion in adult patients with NRAS mutant solid tumors is ongoing in the BeiGene-sponsored Phase 1b trial evaluating mirdametinib in combination with BeiGene’s RAF dimer inhibitor, lifirafenib.
• On track to initiate 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

• The U.S. Patent and Trademark Office has recently issued five new patents for OGSIVEO. The U.S. patent portfolio for OGSIVEO now includes 21 Orange Book listed patents, providing protection into 2043.

First Quarter 2024 Financial Results

• Revenues: OGSIVEO net product revenues were $21.0 million in the first quarter of 2024, the first full quarter of the U.S. launch.
• Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $60.1 million for the first quarter of 2024, compared to $44.2 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.
• Research and Development (R&D) Expenses: R&D expenses were $53.6 million for the first quarter of 2024, compared to $33.5 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 $87.4 million, or $1.18 per share, for the first quarter of 2024. This compares to a net loss of $73.4 million, or $1.18 per share, for the comparable period of 2023.
