Valink Therapeutics

Valink Therapeutics is a clinical-stage biotechnology company developing antibody-drug conjugates (ADCs) for solid tumors using its proprietary ValiLinker technology — a site-specific conjugation platform that precisely attaches cytotoxic payloads to antibodies at defined positions, improving ADC stability, homogeneity, and therapeutic index compared to conventional random-conjugation approaches. Founded in 2020 and headquartered in Houston, Texas, Valink raised $20.5 million total including an $11.8 million Pre-Series A in October 2025 to advance its pipeline into clinical trials.\n\nValink's pipeline centers on VLT-03 (targeting solid tumors in Phase I trials) and VLT-01 (targeting solid tumors with brain metastases, addressing the significant unmet need in CNS-penetrating oncology therapeutics). The ValiLinker conjugation technology enables precise drug-to-antibody ratios and reduces off-target toxicity that has historically limited ADC tolerability — the platform differentiates Valink from earlier ADC developers by addressing the conjugation chemistry precision that drives therapeutic index improvements in this modality.\n\nIn 2025, Valink competes in the ADC space with Seagen (acquired by Pfizer), ImmunoGen (acquired by AbbVie), Daiichi Sankyo (partnered with AstraZeneca), and numerous clinical-stage biotech ADC developers. ADC development has become one of the most active areas in oncology after the commercial success of Enhertu (trastuzumab deruxtecan) demonstrated the potential of the modality. Valink's site-specific conjugation differentiation targets the technical limitations of first-generation ADCs that created toxicity issues. The 2025-2026 strategy focuses on Phase I dose escalation for VLT-03, building clinical proof-of-concept for the ValiLinker platform, and positioning for partnership or licensing discussions with large pharma.
