Hoth Therapeutics received a positive conclusion from the European Union Clinical Trials Information System for Part I of its HT‑001 program, a topical gel designed to treat skin toxicities caused by epidermal growth factor receptor inhibitor (EGFRi) cancer therapies. The approval confirms the scientific and regulatory acceptability of the trial design and investigational product, allowing the company to activate sites and begin enrolling patients across several European countries.

The regulatory milestone is a critical de‑risking event for HT‑001. With the Part I conclusion in place, Hoth can move forward with the planned multi‑country enrollment that will run in parallel with its U.S. program. The company expects country‑specific Part II decisions in Hungary, Spain and Poland by January 19 2026, which will enable rapid, coordinated execution of the study and generate the data needed to support future regulatory submissions.

HT‑001 addresses a substantial unmet need. EGFRi therapies are widely used in oncology but frequently cause severe dermatologic side effects that can lead to dose reductions or treatment discontinuation. No FDA or EMA‑approved treatment exists for these toxicities. Interim data from the Phase 2a CLEER‑001 trial showed a 100 % response rate in a primary endpoint, significant reductions in pain and pruritus, and no patients required dose modification or discontinuation of their EGFRi therapy. The topical gel targets Substance P‑driven inflammatory pathways, offering symptom relief without systemic immunosuppression.

The company’s financial position supports the continued development of HT‑001. As of late 2025, Hoth had a market capitalization of roughly $18 million, no debt, and sufficient cash to fund its current studies. The regulatory approval is expected to enhance the company’s European pipeline profile and could accelerate future funding and partnership opportunities, positioning HT‑001 as a key asset in Hoth’s oncology portfolio.

Robb Knie, CEO of Hoth, said the approval marks a “meaningful regulatory inflection point” for the company’s oncology pipeline. He added that regulators have confirmed the acceptability of the application for this cancer‑related indication, underscoring the company’s progress toward delivering a first‑in‑class supportive‑care therapy for patients experiencing EGFRi‑induced skin toxicities.
