All I read In the SEC is "The Cubist product pipeline includes our lipopeptide program and our natural products screening program." They are conducting several more clinical trials with Daptomycin but I don't see any news from their research collaboration with Ilypsa to develop a non-antibiotic therapy for Clostridium difficile associated diarrhea (CDAD). Since they had discontinued the development of HepeX-B, I'm afraid they are still looking for new candidates in preclinical.
