New drug candidate shows promise in treating MS


The results of a new drug candidate showed a reduced relapse rate and lower levels of new brain damage in MS patients. The drug also shows higher levels of safety for patients.

The drug candidate RPC1063, first discovered and synthesized at the Scripps Research Institute, was tested during a six-month Phase 2 study of 258 multiple sclerosis patients. The results of the drug candidate showed a reduction in the relapse rate by up to 53 percent and decreased new brain damage by more than 90 percent in MS patients. The drug also showed a strong safety profile with nearly all participants staying on the drug regimen during the trial period.

Receptos, a San Diego biopharmaceutical company, is developing RPC1063 for approval by the U.S. Food and Drug Administration. The drug candidate is currently in a Phase 3 randomized, double-blind study involving 1,200 relapsing multiple sclerosis patients. The trial is expected to be completed in 2017.

“These data support our labs’ approach at TSRI that discovery of fundamental mechanisms in chemical biology provides the foundation for intelligent intervention in disease processes,” said Ed Rosen, Scripps California.

The new RPC1063 findings were presented at the MS Boston 2014 meeting.
