Sarepta Therapeutics Inc (SRPT)

History and Background

Sarepta Therapeutics, founded in 1980 as AntiVirals Inc., focused initially on antiviral therapies. In 2012, the company shifted its focus to rare genetic diseases, particularly Duchenne muscular dystrophy (DMD), and rebranded as Sarepta Therapeutics. Key milestones include the FDA approval of Exondys 51, the first disease-modifying therapy for DMD, and subsequent approvals of other exon-skipping therapies and gene therapies.

Core Business Areas

• Genetic Therapies: Development and commercialization of gene therapies for rare genetic diseases, focusing on DMD and other neuromuscular conditions.
• RNA-Targeting Therapies: Development and commercialization of RNA-targeting therapies, primarily exon-skipping drugs, for the treatment of DMD.

Leadership and Structure

Sarepta is led by CEO Michael Andrew. The organizational structure includes research and development, commercial operations, manufacturing, and administrative functions. The company has a board of directors overseeing strategic direction.

Key Offerings

• Elevidys: Elevidys is a gene therapy approved for certain DMD patients. It delivers a shortened version of the dystrophin gene to muscle cells. Competitors include solid tumors from patients receiving AAV-mediated gene transfer. The total US market has 40-50k addressable patients. Revenue is projected to be 750M+.
• Exondys 51: Exondys 51 is an exon-skipping drug for DMD patients with mutations amenable to exon 51 skipping. Revenue contribution is in decline. Competitors include other approved exon skipping drugs from Sarepta and potential future gene therapies. No specific market share data readily available.
• Amondys 45: Amondys 45 is an exon-skipping drug for DMD patients with mutations amenable to exon 45 skipping. Revenue contribution is growing at slower pace. Competitors include other approved exon skipping drugs from Sarepta and potential future gene therapies. No specific market share data readily available.

Industry Overview

The rare disease therapeutics market is characterized by high unmet needs, premium pricing, regulatory incentives (orphan drug designation), and increasing investment in gene and RNA-based therapies. There is high unmet need because 95% of rare diseases have no FDA-approved treatments.

Positioning

Sarepta is a leading player in the DMD therapeutics market, holding a dominant position in exon-skipping therapies and a strong presence in gene therapy with Elevidys. The competitive advantage stems from its early mover advantage and expertise in developing therapies for rare genetic diseases.

Total Addressable Market (TAM)

The total addressable market for DMD therapies is estimated to be in the billions of dollars annually. Sarepta is well-positioned to capture a significant portion of this TAM with its portfolio of approved therapies and pipeline of potential new treatments.

Key Competitors

• VRTX
• BMY
• PFE

Competitive Landscape

Sarepta has a strong position in DMD, but faces increasing competition from other pharmaceutical companies developing gene therapies and other novel treatments. Sarepta's advantage is its established infrastructure and expertise in the field.

Myonexus Therapeutics

• Year: 2018
• Acquisition Price (USD millions): 165
• Strategic Rationale: Acquired Myonexus to expand its gene therapy pipeline into limb-girdle muscular dystrophies (LGMDs).

Historical Growth: Sarepta has experienced significant revenue growth in recent years due to the launch and commercialization of its DMD therapies.

Future Projections: Analysts project continued revenue growth for Sarepta, driven by increasing sales of Elevidys and potential future product approvals.

Recent Initiatives: Recent strategic initiatives include expanding manufacturing capacity for gene therapies, advancing clinical trials for new indications, and pursuing strategic collaborations.

Sarepta Therapeutics is a key player in DMD, showing strength in gene and RNA-based therapies. Their early market advantage and pipeline depth are significant positives. However, they face competition, regulatory hurdles, and high R&D expenses which need to be carefully managed to sustain growth.
