Seres Therapeutics has secured a $250 million senior secured debt facility from Oaktree Capital Management, with $110 million received at closing. This financing supports the commercial launch of VOWST™ and advances the company’s pipeline.
The initial $110 million will retire $53 million of existing debt, leaving around $50 million for operations. The loan carries an interest rate of SOFR + 7.875%, capped at 12.875%, maturing in six years with a possible three-year extension.
With VOWST's FDA approval in April 2023, Seres aims to lead in microbiome therapeutics. The partnership with Oaktree is vital for Seres’ growth, addressing significant medical needs.
Seres Therapeutics announced that the FDA has approved VOWST (fecal microbiota spores, live-brpk), the first orally administered microbiota-based therapeutic for preventing recurrent C. difficile infection (CDI) in adults post-antibacterial treatment. The approval follows the successful Phase 3 ECOSPOR III study, which indicated that 88% of treated patients were recurrence-free at eight weeks. VOWST is expected to be available in June 2023, with a milestone payment of $125 million to Seres from Nestlé Health Science linked to the FDA approval. The joint commercialization effort aims to address a significant unmet medical need as recurrent CDI is a leading cause of hospital-acquired infections. The product does not treat CDI but aims to prevent its recurrence.
