This financing round will enable Adaptam to further develop its programs and enter the preclinical phase in multiple oncology indications. As part of the round, Salvatore Cappadona, PhD, and Pablo Cironi, PhD, both from Criteria Bio Ventures, joined the board of directors.

Adaptam is developing first-in-class antibody-based therapeutic programs, including ADCs and bispecific antibodies, that target novel glyco-immune checkpoints, selectively expressed in immunosuppressive myeloid cells.

"Immunosuppressive myeloid cells within tumors present one of the toughest challenges in immunotherapy today. Our goal is to neutralize this obstacle by developing therapies that specifically target these cells, offering patients new hope where traditional approaches have failed," said Asis Palazon, PhD, founder, CEO and CSO of Adaptam. "The support from Criteria Bio Ventures enables us to take a step forward in achieving our mission. We are now actively planning our next funding round to support IND-enabling studies."

Immunotherapy has transformed cancer treatment, offering new solutions to patients worldwide. However, a significant number still fail to respond to these therapies or develop resistance over time. This lack of efficacy is primarily due to the immunosuppressive nature of the tumor microenvironment (TME), which hampers the immune system’s ability to effectively target and destroy cancer cells. Among the main contributors to this immunosuppression are myeloid cells, particularly TAMs, which play a crucial role in inhibiting T-cell responses. This challenge is particularly pronounced in patients with solid tumors, where these myeloid cells create an environment that prevents immune cells from mounting an effective anti-tumoral response.

"We are thrilled to support Adaptam in its mission to transform cancer treatment by targeting the immunosuppressive cells within the TME. The scientific breakthroughs achieved by Prof. Asis Palazon and his team have laid the groundwork for potentially life-changing therapies," said Pablo Cironi, PhD, chairman of the Adaptam board. "With this strong foundation, we believe Adaptam is well-positioned to deliver new, effective treatments for patients with solid tumors, addressing critical gaps in current immunotherapy options."

"Adaptam’s differentiated approach at the intersection of myeloid-mediated immunosuppression and glycobiology represents a one-of-a-kind vision uniquely positioned to unlock the next frontier in cancer immunotherapy. We are proud to have partnered with Asis Palazon to build this exciting new venture and support its next phase of development. We are confident that Adaptam’s emerging pipeline offers a game-changing opportunity to transform cancer treatment for many patients," said Salvatore Cappadona, PhD, board member of Adaptam.

Adaptam originated from research conducted by Prof. Asis Palazon and his team at CIC bioGUNE in Bilbao, Spain, with expert insights from Criteria Bio Ventures on the ideation, corporate strategy and operational setup of the company. Asis Palazon also received a Caixa Research Health grant from "la Caixa" Foundation in 2021. Some of the core structural and mechanistic discoveries of immune-modulating glycan-binding proteins and their interactions with immune cells were previously published in Nature Communications.

"CIC bioGUNE’s long-standing leadership in glycobiology provided the scientific foundation for Adaptam and we have supported the company from its earliest steps through to today’s preclinical maturation," said Prof. Jesús Jiménez-Barbero, scientific director of CIC bioGUNE.
