Aisa Pharma Orphan Status for Cilnidipine
FDA has granted Aisa Pharma an orphan drug designation for its investigational drug AISA-021 (cilnidipine) and its use in treating systemic sclerosis (SSc), a rare and severe autoimmune disease affecting approximately 175,000 Americans. SSc has the highest mortality rate among autoimmune diseases, according to the company, and it is marked by its debilitating symptoms, including severe pain and compromised organ function.
The designation is based on preliminary data from an ongoing Phase 2 study, which indicates that AISA-021 may offer significant benefits over existing treatments. Aisa Pharma says the study has shown promising results, including improvements in overall disease severity, pain management, gastrointestinal symptoms, skin ulcers, disability, and breathing difficulties. Additionally, the data suggest a lower incidence and severity of side effects compared to current therapies, with improved efficacy in preventing Raynaud’s attacks, it says.
Aisa Pharma says it has scheduled a Pre-IND meeting this month to discuss AISA-021’s development for both SSc secondary Raynaud’s Phenomenon. The company says it is also awaiting further results from initial drug screenings performed by the NIH, which assessed AISA-021’s potential as a non-opioid analgesic and found no evidence of abuse liability or addictive potential.
AISA-021, a form of cilnidipine, is known for its increased selectivity for N-type calcium channels and is already used for hypertension in certain Asian countries, the company says.
