An IND is a request for authorization from the FDA to administer an investigational drug or biological product to humans. Signature Biologics applied for the IND for Signature Cord Prime™ to begin clinical study of the product, working towards a full Biologics Licensing Application (BLA) with FDA’s Center for Biologics Evaluation and Research (CBER).

“This represents a push for regenerative medicine as the first hUC [human umbilical cord] product of its kind to receive approval to be studied in osteoarthritis of the knee,” said Dr. Neil Riordan Ph.D., CEO of Signature Biologics. “We are pleased that FDA has enabled us to proceed and we are grateful for the partnership.” The FDA granted IND approval based on multicenter, retrospective clinical evidence from 135 knees treated with Signature Cord™ that demonstrated both safety and statistically significant reduction in pain and improvement in function.

Osteoarthritis is the most common form of arthritis, affecting more than 32.5 million Americas and more than 500 million worldwide. According to the CDC, OA was the second most costly health condition treated at US hospitals in 2013, at $16.5 billion or 4.3% of the combined costs for all hospitalizations. In 2015, the US financial cost of OA was estimated to reach $200 billion annually or 1.1% of GDP. Knee replacement surgeries required in the U.S. are growing every year and are expected to rise to 1.28 million Americans by 2030.
