Waltham, Mass., August 18, 2021 – Immunitas Therapeutics (“Immunitas”), a single cell genomics-based therapeutics company, today announced the completion of a $58 million Series B financing led by Agent Capital with participation from Medical Excellence Capital (MEC), 120 Capital, Solasta Ventures, Mirae Asset, Ono Venture Investment, The Mark Foundation for Cancer Research, NS Investment, BrightEdge (American Cancer Society), and The Leukemia & Lymphoma Society Therapy Acceleration Program® (LLS TAP). Existing investors Alexandria Venture Investments, Evotec, Leaps by Bayer, M Ventures, Novartis Venture Fund (NVF), and founding investor Longwood Fund also joined the round. As part of the financing, Geeta Vemuri, PhD, MBA, Managing Partner and
Founder of Agent Capital, and Brian Halak, PhD, on behalf of MEC will join the Immunitas Board of Directors.

“Immunitas has made tremendous strides in the past year. This Series B financing is a key inflection point for the company and will enable us to drive IMT-009 rapidly into the clinic, while continuing to build and validate our pipeline of novel oncology programs,” said Jeffrey Goldberg, Chief Executive Officer of Immunitas Therapeutics. “Our single cell technology platform allows our team to incorporate insights from human biology throughout the discovery and
development process, enabling us to rapidly move towards serving patients in need.”

The Series B funding will be used to advance Immunitas’ lead program, IMT-009, a CD161 inhibitor, into the clinic to treat both solid tumors and hematological malignancies. Both blockade and knockout of CD161 in preclinical systems have shown enhanced tumor-killing, increases in critical cytokines, and increased survival. The company expects to file its first Investigational New Drug application (IND) in 1H 2022 for IMT-009. This financing builds on the $39 million
Series A financing secured in 2019. Immunitas Therapeutics was founded by Kai Wucherpfennig, MD, PhD, DanaFarber Cancer Institute, K. Dane Wittrup, PhD, the Massachusetts Institute of Technology (MIT), Mario Suvà, MD, PhD, Massachusetts General Hospital (MGH), and Aviv Regev, PhD, MIT.

“Immunitas is focused on creating impactful therapies that modulate oncology targets, driven by a cross-functional
platform that combines single cell analysis computation and molecular and cellular biology to rapidly identify and
validate new targets,” said Geeta Vemuri of Agent Capital. “This approach is well suited to provide powerful
translational insights into biomarker and indication selection with long-term potential beyond IO.”

In addition, Amanda Wagner, MBA, has been appointed Chief Business Officer in recognition of her significant contributions to the company’s business and corporate development.
