Emily M. Leproust, Ph.D., CEO and co-founder of Twist Bioscience commented: “In launching Revelar Biotherapeutics, we assembled an experienced executive leadership team with a proven track record of successful clinical and corporate development together with access to a series of antibody therapeutic leads. This transaction allows Twist to participate in the rapid advancement of therapeutic antibodies while remaining focused on our current opportunities in our core business as well as our biopharma and DNA data storage verticals. We look forward to having our first Twist Biopharma-discovered antibody enter clinical studies in 2022, pending the necessary requirements.”

“In parallel with the development of the antibody to treat SARS-CoV-2, which we believe has the potential to be delivered subcutaneously, we intend to build a pipeline of novel therapeutics by leveraging the robust Twist Biopharma antibody discovery and optimization platform,” commented David Scheer, chairman of the board of Revelar Biotherapeutics. “Pairing Twist’s ability to identify single domain and multifunctional antibodies combined with the broad development expertise of the Revelar team sets the stage to move the needle in treating unmet medical needs.”

Twist Bioscience granted a license to Revelar for the exclusive development of an antibody lead along with a series of back up compounds for the potential treatment of SARS-CoV-2. Twist may receive success-based milestone payments totaling over $100 million for the achievement of key development, regulatory and commercial milestones, as well as mid-single digit royalties on any future net sales. In addition, Revelar may license up to five additional antibody therapeutics over the next four years, each of which will be subject to additional upfront, milestone and royalty payments to Twist.

Twist has committed to invest up to $10 million in seed funding based on Revelar’s progress in the development of the lead antibody and the potential licensing of additional antibody therapeutics. In exchange for its cash investment, the antibody, and its back-up compounds, Twist received significant minority ownership in Revelar.

Revelar’s executive leadership team includes Glenn Marina (CEO), Kevin Malobisky (chief regulatory and quality officer), Laurence Smith (CFO and general counsel), and Rodrigo Mesquita (vice president of operations and project management). The board will be comprised of David Scheer (chairman), Paul Fonteyne, Brett Giroir, Emily Leproust (Twist Bioscience’s CEO and co-founder) and Patrick Finn (Twist Bioscience’s chief commercial officer).

“Building on data from a peer-reviewed publication in Science, Twist Biopharma optimized an antibody that neutralizes all known SARS-CoV-2 variants of concern,” said Glenn Marina, CEO of Revelar. “We look forward to completing preclinical and CMC development in support of filing an Investigational New Drug (IND) application that supports the initiation of clinical studies.”
