“We are extremely pleased to partner with Humanigen in the fight against COVID-19 and to use our unique position as a US-based manufacturer to help simplify and secure a key part of their supply chain,” said Kristin DeFife, Ph.D., Sr. VP of Operations & Site Head at Ajinomoto Bio-Pharma Services. “Through this collaboration we uphold our mission to improve the health of humankind, and our employees take great pride in knowing that our efforts may ultimately help patients survive this devastating disease.”

Under the terms of the agreement, Aji Bio-Pharma will provide drug product aseptic fill finish services for Humanigen at its San Diego facility.
