Frequently asked questions about SB-509

What is SB-509 used for?

SB-509 is an investigational small molecule being developed for Type 1 Diabetes Mellitus and Amyotrophic Lateral Sclerosis (ALS). In clinical trials, it has also been studied in patients with diabetic polyneuropathy, a complication of diabetes. It is currently in Phase 2 clinical development.

Who makes SB-509?

SB-509 is being developed by Sangamo Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol SGMO. The company has conducted multiple clinical trials of SB-509 in diabetic neuropathy and ALS.

What phase is SB-509 in?

SB-509 is in Phase 2 clinical development. All four clinical trials for SB-509 have been completed, with no active trials currently ongoing. The drug remains investigational and has not been approved by regulatory authorities.

What clinical trials is SB-509 in?

SB-509 has been studied in four completed Phase 2 clinical trials. These include NCT00476931 and NCT01079325 in diabetic neuropathy, NCT00665145 in stem cell mobilization for diabetic neuropathy, and NCT00748501 in amyotrophic lateral sclerosis (ALS). Total enrollment across these trials was 394 participants.

Is SB-509 the same as a gene therapy?

SB-509 is classified as a small molecule therapeutic, not a gene therapy. It is being developed by Sangamo Therapeutics for the treatment of Type 1 Diabetes Mellitus and Amyotrophic Lateral Sclerosis. The drug has been evaluated in randomized, active-controlled clinical trials.
