New US Patent Covering CVT-301 Composition Expands Extensive Patent Estate
CHELSEA, Mass. – Civitas Therapeutics, Inc., a biopharmaceutical company with a lead program in Parkinson’s disease that leverages the ARCUS® respiratory delivery platform, today announced the Unites States Patent and Trademark Office (USPTO) has issued US Patent 8,545,878 entitled “Capsules containing high doses of levodopa for pulmonary use.” This newly issued patent covers the pharmaceutical composition of CVT-301 and has an expiration date of November 16, 2032. US 8,545,878 is one of over 115 issued patents worldwide protecting CVT-301.
“This newly issued patent further fortifies and extends our robust patent estate covering CVT-301,” said Glenn Batchelder, Chief Executive Officer and Co-founder of Civitas. “The ARCUS® platform’s unique capabilities and versatility provide a wealth of opportunities for continued innovation thereby broadening and deepening our patent estate around both the platform and CVT-301.”
Civitas’ lead program, CVT-301, is an inhaled formulation of L-dopa being developed for the rapid and reliable relief from debilitating motor fluctuations (OFF episodes) associated with Parkinson’s disease. Oral L-dopa, used for chronic symptom management, is administered to maintain dopamine levels in the brain above the therapeutic threshold; however, the reliability of oral L-dopa formulations is significantly compromised by delayed and unpredictable absorption and excessive variability in circulating plasma drug concentrations inherent to the oral delivery route. L-dopa remains widely recognized as the most efficacious treatment for Parkinson’s disease symptoms in spite of this intrinsic unreliability, which results in OFF episodes. CVT-301 is being developed as an adjunct PRN therapy to standard oral L-dopa therapy to address OFF episodes as they emerge and enable patients to reliably manage their symptoms.
CVT-301 leverages the ARCUS® platform to optimally deliver a precise dose to the deep lung for rapid and predictable L-dopa absorption. The ARCUS® platform is uniquely able to deliver the necessary L-dopa dose with the required precision. A Phase 1 study in healthy volunteers showed that CVT-301 rapidly achieved target L-dopa plasma levels with a pharmacokinetic (PK) profile supportive of its therapeutic potential. The recently completed Phase 2a double blind placebo controlled dose finding study (CVT-301-002) recapitulated the PK profile in patients, produced rapid and durable improvement in motor function when administered to patients in the OFF state, and was generally safe and well tolerated at all doses tested. Civitas is currently conducting a Phase 2b study to evaluate the efficacy and safety of CVT-301 in treating emergent OFF episodes during one month of continued use. CVT-301 clinical studies conducted to date have been funded in part by grants from The Michael J. Fox Foundation for Parkinson’s Research.
About Parkinson’s Disease
Over one million people in the US and six million people worldwide suffer from Parkinson’s disease, a neurodegenerative disorder caused by diminished production of dopamine in the substantia nigra area of the brain, resulting in progressive impairment of motor function including tremors, rigidity, and difficulty in moving. The unreliability of available medications for symptomatic treatment of Parkinson’s disease remains a significant unmet need. Even when treated with the current standard of care, the majority of Parkinson’s patients continue to experience motor fluctuations. These unpredictable OFF episodes reduce patients’ ability to lead productive, independent lives and are recognized by patients, care givers, and healthcare professionals as one of the most troubling and debilitating issues associated with the disease.
About ARCUS® Platform
The ARCUS® platform is a proprietary dry powder and device combination with a unique ability to deliver a large, precise dose independent of inspiratory flow rate from a simple, breath actuated device.
