Speedel (Swiss:SPPN.SW - News) today announced that it has reached another significant milestone in the development of its family of renin inhibitors with the successful completion of a Phase IIa proof-of-concept clinical trial with SPP635 for the treatment of hypertension. Based on these positive results, the company is to continue developing SPP635 in Phase II in a special population of diabetic patients with mild-to-moderate hypertension. This compound is the first of a next generation of renin inhibitors following Speedel’s lead product SPP100 (aliskiren, Tekturna/Rasilez[1]), which is partnered with Novartis and recently obtained US marketing approval from the FDA and a positive opinion from the CHMP in Europe[2]. SPP635 is the most advanced compound in the SPP600 series and is one of several new proprietary renin inhibitors invented by Speedel Experimenta, the company’s late-stage research unit.
