What Akamis Bio does

Akamis Bio is a clinical-stage oncology company developing systemically administered, tumor-specific oncolytic immunotherapies based on its proprietary T-SIGn (Tumor-Specific Immuno-Gene) platform. The platform uses a replication-competent chimeric group B adenovirus backbone, optimized via directed evolution, to selectively target epithelial-cell-derived solid tumors after intravenous delivery while sparing healthy tissue, and to deliver immunotherapeutic transgene payloads — including antibodies, bispecifics, chemokines, cytokines, and synthetic constructs — directly into the tumor microenvironment.

The company's lead candidate, NG-350A, drives intratumoral expression of a secreted CD40 agonist monoclonal antibody to activate antigen-presenting cells and recruit T cells, and is currently being evaluated in the Phase 1b FORTRESS trial (NCT06459869) in patients with mismatch repair-proficient (pMMR) locally advanced rectal cancer (LARC). NG-348, a second clinical-stage T-SIGn candidate, expresses membrane-bound CD80 and an anti-CD3 scFv for direct T-cell engagement in metastatic colorectal cancer. In April 2026 the company reported preliminary FORTRESS data showing a 50% composite response rate in the first 10 patients treated with NG-350A plus chemoradiotherapy versus a 25% benchmark for chemoradiotherapy alone, with no new safety signals.

Akamis Bio is pre-revenue with no commercialized products. Its business model relies on advancing pipeline assets through clinical proof-of-concept, securing regulatory designations such as the FDA Fast Track Designation received in October 2025 for NG-350A, and monetizing through regional licensing partnerships — most notably the December 2024 deal granting Xuanzhu Biopharma Greater China rights to NG-350A in exchange for undisclosed upfronts, regulatory and sales milestones, and tiered royalties in the high single- to low double-digit range. The company is led by CEO Howard Davis, PhD, is headquartered in Cambridge, Massachusetts, and has approximately $90 million in cumulative funding as of late 2024.

Core offering

Akamis Bio develops systemically administered, tumor-specific oncolytic immunotherapies using its proprietary T-SIGn (Tumor-Specific Immuno-Gene) platform, which is built on a replication-competent chimeric group B adenovirus backbone optimized via directed evolution to selectively replicate within epithelial-cell-derived solid tumors following intravenous delivery. Its lead clinical-stage candidate, NG-350A, drives intratumoral expression of a CD40 agonist monoclonal antibody to treat pMMR locally advanced rectal cancer, while NG-348 expresses membrane-bound CD80 and anti-CD3 scFv for metastatic colorectal cancer. The company monetizes the platform through licensing deals with pharmaceutical partners (e.g., Xuanzhu Biopharma for Greater China rights) and pursues further co-development partnerships.

Product overview

Akamis Bio is a clinical-stage oncology company developing a portfolio of oncolytic immunotherapies based on its proprietary T-SIGn (Tumor-Specific Immuno-Gene) platform. The platform delivers immunotherapeutic transgene payloads via systemically administered, tumor-specific adenoviral vectors. The company's lead clinical-stage product is NG-350A, which drives intratumoral expression of a CD40 agonist monoclonal antibody for treating pMMR locally advanced rectal cancer (with FDA Fast Track Designation). NG-348 is a second clinical-stage candidate expressing CD80 and anti-CD3 scFv for metastatic colorectal cancer. The T-SIGn platform has also been used in partnership collaborations including with Xuanzhu Biopharma (Greater China licensing agreement) and earlier collaborations with Merck and Cancer Research Institute.
