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.

On October 27, 2025 OncoNano Medicine, Inc. ("OncoNano") reported encouraging first-in-human results from Part 1 of its Phase 1 ON-5001 trial evaluating ONM-501, a dual-acting STING agonist, as monotherapy and in combination with Libtayo (cemiplimab), Regeneron’s PD-1 inhibitor, in patients with advanced solid tumors and lymphomas. The findings were shared during a poster presentation at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in Boston, Massachusetts.

ONM-501 is designed to activate the STING pathway and stimulate both innate and adaptive immune responses within the tumor microenvironment. By linking a cyclic dinucleotide (cGAMP) to a proprietary polymer, ONM-501 prolongs STING activation and overcomes key limitations of earlier STING agonists. In preclinical models, this approach produced durable anti-tumor responses without triggering systemic inflammation, an effect now supported by emerging clinical results.

In the dose-escalation and dose-finding study, ONM-501 was well tolerated and demonstrated early signs of clinical benefit. Among 39 patients treated (15 with ONM-501 monotherapy and 24 in combination with cemiplimab), no dose-limiting toxicities were observed, and the most common adverse events were mild fatigue and injection-site reactions. Systemic interferon-γ levels remained within normal limits across all cohorts.

In the monotherapy arm, one patient achieved an objective response and three patients had prolonged stable disease, including a case of recurrent, immunotherapy-refractory uveal melanoma with disease control lasting over one year (390 days). In the combination arm, five patients experienced objective responses, including two complete in patients with cutaneous squamous cell carcinoma (cSCC).

"These data provide the first clinical evidence that sustained STING activation through our proprietary polymer conjugate can drive meaningful immune responses in solid tumors," said Kartik Krishnan, MD, PhD, Chief Executive Officer of OncoNano Medicine. "The safety profile and emerging efficacy signals, particularly in patients with advanced cutaneous malignancies, highlight the potential of ONM-501 to expand the reach of STING-based immunotherapy."

Part 2 of the ON-5001 study (NCT06022029) is now open and enrolling patients with advanced basal cell carcinoma, cutaneous squamous cell carcinoma and melanoma.

About ONM-501
ONM-501 is a dual-activating agonist of the stimulator of interferon genes ("STING") pathway composed of cGAMP (the endogenous activator of STING) linked to a proprietary pH-activated polymer (the OMNI polymer). ONM-501 is presently being studied in a Phase 1 clinical trial (ON-5001). In preclinical models, the dual activation of STING by ONM-501 has been shown to lead to a direct anti-tumor effect, as well as leading to an anti-tumor immune response over an extended period of time. Development of ONM-501 was funded in part by the Cancer Prevention and Research Institute of Texas.

The contributing teams utilized a novel approach, implanting patient-derived thymic cells generated via direct differentiation of induced pluripotent stem cells (iPSCs) into thymectomized and humanized immune-deficient mice, along with matched tumor tissues from a patient with metastatic melanoma. The key finding was that tumors implanted in mice with human thymic tissue grew significantly slower compared to tumors implanted in control and in humanized mice without thymic tissue. Viable melanoma content was also significantly decreased in mice bearing thymic organoids, associated with an increase in intra-tumoral activated T-cells. Whole gene sequencing identified multiple candidate neoantigens that were eliminated in cancer cells in thymus-bearing mice, suggesting a more effective identification and T-cell-driven tumor clearance.

"An experiment is only as good as the models used to conduct it. Over the last 15 years, we have generated increasingly complex laboratory and mouse models that can bear both human immune and cancer cells, which we call humanized mice, to realize the promise of immune therapy. A fundamental limitation of humanized mice, generated with donor blood stem cells and implanted with mismatched patient tumors, is that the fidelity of the interaction between the immune and tumor cells is limited by lack of the organ that facilitates immune cell education, the thymus," said Dr. Jimeno.

"Here we report the successful generation of a novel model that incorporates functional thymic organoids derived from iPSC generated using patient peripheral blood with tumors from the same patient, providing an important step towards improved personalized models," remarked Dr. Russ.

"These results represent meaningful advance in oncology, both from a therapeutic and a diagnostic point of view, as iPSC thymic cells have the potential to serve as a cell therapy for cancer, alone or along immune agents, the patient derived xenograft model can improve new drug development by more accurately identifying promising drugs and vaccines, and it will allow for personalized medicine by testing which immune therapy is more likely to work for a specific patient," added Dr. Jimeno. "We have a lot of work ahead, but I am looking forward to extending our interdisciplinary work into the future to realize this potential."

"Tolerance Bio is proud to collaborate with Dr. Jimeno and Dr. Russ, and their superb teams at U. Colorado and U. Florida. Their work lays the foundation for the use of iPSC thymic cells in immune diseases, including cancer," said Dr. Francisco Leon, M.D., Ph. D., CEO of Tolerance Bio. "The changes in the tumor growth kinetics provide critical proof of principle for the ability of iPSC thymic cells to reconstitute a T cell immune system in vivo with beneficial functional consequences. As we advance towards the clinic, we have developed a robust manufacturing process for our allogenic, off-the-shelf iPSC thymic cell product, and we plan to initiate pre-investigational new drug (IND) studies in the near future."
