F1 Oncology to Present Data That Expands on Proof of Novel Point of Care Approach for CAR-T Therapies in Solid Tumor Malignancies

Data Presented at 2019 AACR Annual Meeting Supports Novel
Conditionally Active Biologics CAR-T Technology

ATLANTA–(BUSINESS WIRE)–F1 Oncology, Inc., a biotechnology company discovering and developing
adoptive cellular therapies (ACTs) for solid tumors, will present four
abstracts at the American Association of Cancer Research (AACR) 2019
Annual Meeting in Atlanta from March 29-April 3, 2019 that support novel
technologies to treat solid tumor malignancies.

F1 Oncology is developing these novel CAB-CAR-T therapies to target
solid tumors while minimizing the potential of on-target, off-tumor
activity. The four abstracts provide insight into the use of the
company’s proprietary CAB-CAR-T technology to increase the potential
safety of CAR-T therapeutics by turning the negative effects of the
tumor microenvironment (TME) into activating signals. They will
highlight proof of concept studies of same-day, point of care CAR-T and
use bioinformatics data driven methods to discover protein domain
combinations capable of selectively expanding CAR-T cells.

“The data to be presented highlight scientific progress that may greatly
simplify CAR-T therapy for solid tumor malignancies in the future,” said
Gregory Frost, Ph.D., Chairman and CEO of F1 Oncology. “The teams have
also made significant progress in our understanding of CAB-CAR-T’s role
in adoptive cellular therapy for solid tumors, and we look forward to
seeing the progress from ongoing clinical studies with these programs
through collaborators in Shanghai.”

The abstracts are available in the program section of the annual AACR
meeting website, and details for the poster presentations are as follows:

• Same day transduction and in vivo expansion of chimeric antigen
  receptors and synthetic driver constructs for adoptive cellular therapy

  Examining
  the relationship between limiting the ex vivo expansion time and less
  differentiated CAR-T products with enhanced effector function, as well
  as the development of a point of care approach to ACT and its
  potential to reduce the complexity of CAR-T cell immunotherapy.
