Secured $105M non-dilutive financing, extends cash runway into H2 2029, funds Phase 2 development.

Spero Therapeutics has secured $105 million in non-recourse, non-dilutive financing from affiliates of Healthcare Royalty, a business of KKR. The proceeds will primarily fund the Phase 2 development of SP001, Spero's lead immunology candidate, a third-generation anti-CD40L monoclonal antibody in-licensed from Innovent Biologics. The transaction strengthens Spero's balance sheet and extends its expected cash runway into the second half of 2029. The stock price declined about 9% on Tuesday pre-market.
