Precigen Reports 3rd Quarter 2022 Financial Results and Progress of Clinical Programs.

GERMANTOWN, Md: Precigen, Inc. (Nasdaq: PGEN), a biopharmaceutical company specializing in the development of innovative gene and cell therapies to improve the lives of patients, today announced third quarter 2022 financial results and progress of clinical programs.

"Focusing and prioritizing our portfolio has led to rapid progression of our clinical programs. We are exceptionally pleased with the pace and results we are seeing from our portfolio, especially for the PRGN-2012 AdenoVerse Immunotherapy study in RRP, and are excited to showcase data at an investigator-led virtual R&D event in January. We expect the data will make a compelling case for the potential of PRGN-2012 to address the underserved RRP patient population and provide validation for the highly differentiated, first-in-class AdenoVerse therapeutic platform," said Helen Sabzevari, PhD, President and CEO of Precigen. "We also have multiple data presentations at ASH in December, which will highlight continued safety and efficacy of the UltraCAR-T platform."

"Precigen continues to exercise financial prudence and we believe our cash runway is sufficient to advance our clinical priorities into Q4 2023," said Harry Thomasian Jr., CFO of Precigen. "Utilizing proceeds from the sale of Trans Ova, through today, we have been able to retire $144.0 million of the outstanding convertible notes due in July 2023. Retiring this debt, combined with our efforts to streamline and improve our operational efficiencies, further strengthens our financial position and significantly reduces our interest burden through the term of the notes."
