Tagworks Pharmaceuticals BV (“Tagworks”), the pioneer of Click-to-Release chemistry for improved systemic therapies, has secured $65 million in a Series A financing round. Ysios Capital and Gilde Healthcare led the funding, joined by Novartis Venture Fund, New Enterprise Associates (NEA), Lightstone Ventures, Meneldor, and Oost NL. The investment will support the advancement of Tagworks’ lead program, TGW101, and the expansion of its proprietary Click-to-Release platform.

Click-to-Release Platform for Controlled Drug Release

Tagworks’ Click-to-Release platform facilitates controlled drug release through an in vivo click reaction triggered by a specific molecule. This innovative approach enables on-target activation of antibody-drug conjugates (ADCs) and immunomodulators, as well as off-target deactivation of radiopharmaceuticals, thereby improving safety and therapeutic efficacy.

The platform allows ADCs to release their payloads in the tumor microenvironment, expanding their applicability beyond internalizing targets and enabling the killing of heterogeneous tumors with varied target expression. Tagworks’ technology also offers precise on-target activation of immunomodulators and off-target deactivation of radiopharmaceuticals, enhancing safety and widening their therapeutic index.

Advancing TGW101 and Expanding Pipeline

The financing will primarily support the development of TGW101, Tagworks’ lead click-cleavable ADC program. TGW101 targets tumor-associated glycoprotein 72 (TAG72), a clinically validated non-internalizing target widely expressed in solid tumors. By enabling controlled drug release and activation within the tumor microenvironment, TGW101 aims to effectively kill tumors with heterogeneous target expression, a challenge faced by current therapies. The proceeds will also contribute to the expansion of Tagworks’ pipeline, which focuses on oncology.

Broad Applications and Intellectual Property

Tagworks possesses a broad intellectual property portfolio for in vivo Click-Conjugation and Click-to-Release technology. The platform is compatible with small molecules, peptides, antibodies, and larger biomolecules, enabling the development of a wide range of toxin and immunomodulator classes. Beyond TGW101, Tagworks is exploring additional programs in ADCs and radiopharmaceuticals at the discovery phase.

Expert Leadership and Investor Support

Tagworks has appointed Chris Martin, DPhil, former CEO of ADC Therapeutics, as the Chairman of the Board, and Jay Feingold, M.D., Ph.D., former Chief Medical Officer of Pyxis Oncology and ADC Therapeutics, as Chief Medical Officer. The company has attracted a strong international syndicate of investors, including Ysios Capital, Gilde Healthcare, Novartis Venture Fund, NEA, and Lightstone Ventures. The collective expertise and financial support will accelerate Tagworks’ development efforts and expansion into transformative cancer therapies.
