The team is comprised of growth-oriented executives with a long track record of value creation across industries, including life sciences, bringing over 100 years of combined investing and operating experience to this business combination.

Comera Overview

Comera is leading a compassionate new era in medicine and applying a deep knowledge of formulation science and technology to transform essential biologic medicines from intravenous (IV) to SQ forms. The goal of this approach is to provide patients with the freedom of self-injectable care, reduce institutional dependency and drive cost savings across the healthcare system. The biologics market is substantial in size and growing rapidly. Currently, seven out of the top 10 global medicines are biologics¹ and, by 2025, it is expected that the global market for biologics will reach over $420 billion.²

To drive this transformative approach, Comera is applying its innovative formulation platform, SQore, to develop a portfolio of proprietary SQ therapeutics with the goal of lowering healthcare costs, making it easier for patients to administer their medicines, and ultimately enhancing patients’ lives. Comera will also continue to collaborate with pharmaceutical and biotechnology companies, applying its SQore platform to partners’ biologic medicines to deliver enhanced formulations that facilitate self-injectable care.

The Comera team includes compassionate pharmaceutical executives, patient-centric medical doctors, and industry-leading experts in pharmaceutical product development, colloid chemistry, and interfacial dynamics that complement its leadership in traditional protein chemistry. The Company’s combined protein and small molecule capability leverages a mechanistic understanding of protein-protein and protein-solvent interactions to tailor excipient selection for specific formulation needs. This unique scientific foundation supports the SQore platform for formulation work.

OTR and Comera Comments

“We are very excited to support Comera as it develops a new generation of bio-innovative medicines, which are intended to expand patient access, safety, and convenience, reducing healthcare costs while improving quality of life,” said Nicholas J. Singer, Chairman and Chief Executive Officer of OTR. Mr. Singer continued: “We believe the transaction with Comera will enable an attractive entry point and valuation for OTR’s investors within the biologics market with the potential for significant upside as Comera executes on its business plan.”

“There is tremendous opportunity in this multi-billion dollar market to transform the patient treatment experience. We are excited to welcome OTR as partners through this transaction and look forward to our evolution as a public company. This will play a key role in advancing our innovative platform, pipeline, and partnerships to provide essential biologic medicines in subcutaneous forms,” said Jeff Hackman, President and Chief Executive Officer of Comera.

“Patients battling illnesses with intravenous infusion therapies often turn their lives upside down to access therapy at infusion centers, and costly, intense treatment regimens can also disrupt quality of life and impact compliance. At Comera, we are devoted to helping our patients live a full life regardless of their prognosis,” said Neal Muni, M.D., Chief Operating Officer of Comera.
