Antheia Announces New Financing and Plans to Construct Pilot Plant Facility for Biomanufacturing

Financing will support new plant at Antheia headquarters to accelerate scale up for company’s pipeline of plant-based compounds; plant expected to be operational by 2023

MENLO PARK, Calif.June 22, 2022 /PRNewswire/ — Antheia, a synthetic biology company enabling next-generation plant-inspired medicines, today announced $40 million in venture debt financing from Oxford Finance LLC and Silicon Valley Bank, alongside plans to construct a new pilot scale biomanufacturing facility. The financing will support Antheia’s expansion with a 14,700 square-foot pilot plant located next to Antheia’s headquarters in Menlo Park, CA. The new pilot plant will enable the company to significantly improve efficiency and support the scale up of its growing portfolio of products.

“Pilot plants are an essential component of scaling with biomanufacturing, and high-quality pilot plant capacity is increasingly scarce in the U.S.,” said Zack McGahey, Chief Operating Officer at Antheia. “As we advance our entire pipeline of pharmaceutical candidates, investing in our own on-site facility will be critical for optimizing strain performance and improving efficiency as we move to industrial scale production.”

The planned facility will provide Antheia with 500L of additional fermentation capacity to support the scale up of various active pharmaceutical ingredient (API) candidates. By utilizing this facility, the company anticipates two to four months of time savings per run, improved customer engagement through accelerated sampling and validation timelines, and increased utilization rates. Antheia will begin construction in 2023 with the goal to be operational by the end of 2023.

“Antheia is utilizing synthetic biology to create both existing and new medicines in more controlled and economical ways,” said Christopher A. Herr, Senior Managing Director at Oxford Finance. “We are pleased to partner with Silicon Valley Bank to support Antheia’s facility expansion and its growing pipeline of products.”

“We’re thrilled to support Antheia and their mission to disrupt the traditional agricultural-based supply chain and accelerate the discovery of new medicines,” said Peter Sletteland, Director of Life Science and Healthcare at Silicon Valley Bank. “As lenders with a focus on the longer-term growth trajectory, we are excited about the company’s future.”

Antheia aims to transform the supply chain for plant-based APIs that are critical to the development of many essential medicines, yet reliant on fragile, unpredictable, inefficient, and costly agriculture-based sources. Using synthetic biology, Antheia is developing several classes of plant-based APIs that can’t be manufactured through synthetic chemistry, including analgesics, neurotransmitter inhibitors, sedatives, chemotherapeutics, and antiinfectives. This financing enables Antheia’s strategic investment in a pilot plant, which will be instrumental in optimizing the scale-up process for the company’s pipeline of plant-based compounds, which is aligned with the FDA and WHO lists of essential medicines.

In addition to the announcement of its new pilot plant, Antheia has also joined the Association for Accessible Medicines (AAM). The AAM was founded to improve access to safe, high-quality, and effective medicines to all and is well aligned with Antheia’s mission to transform pharmaceutical supply chains to ensure equitable access to critical medicines.
