Cara Therapeutics Initiates Phase 1 Clinical Trial of Novel Analgesic, CR845

SHELTON, Conn., April 28 /PRNewswire/ -- Cara Therapeutics, Inc. today announced that it has initiated a Phase 1 clinical trial of its long-acting peripheral kappa opioid receptor agonist, CR845. The Phase 1a single-center clinical trial will evaluate the safety, tolerability, pharmacokinetic profile, and pharmacological activity of CR845 in a double-blind, randomized, placebo-controlled, single escalating intravenous dose study in 58 healthy male and female volunteers.

The company is also developing oral and subcutaneous formulations of CR845.

About CR845

In preclinical studies, CR845 was highly selective for the peripheral kappa opioid receptor. Animal studies indicate that CR845 is effective in treating pain of inflammatory, neuropathic and visceral origin and exhibits analgesic efficacy for up to 18 hours after a single dose. Analgesic activity was seen after intravenous, subcutaneous, or oral administration. Unlike currently marketed opioids, CR845 did not inhibit intestinal transit (ileus) or elicit signs of addiction in animal models. Preclinical studies also indicate that CR845 possesses anti-itch activity.
