BioVersys AG, a Swiss antibiotic developer, has expanded a collaboration with GSK Plc to accelerate development of a candidate product for tuberculosis. The product, alpibectir, has reached Phase 2a and shown an ability to increase the efficacy of ethionamide, an existing antibiotic. GSK will take an equity stake in a Series C financing extension for the company, raising the total proceeds from the round to CHF 44.9 million ($49.4 million). The size of the equity stake wasn’t disclosed. The new agreement was announced on 7 May.
