Intratumoral Targeted Hyperthermia Therapy (THT) for Cutaneous Metastatic Melanoma

Brief Summary

This device phase I/II, first in human, early feasibility study (EFS), open-label, single-arm trial aims to evaluate the safety, tolerability, and preliminary efficacy of Gold Nanorod (GNR)-enabled sub-ablative targeted hyperthermia therapy (THT) in patients with unresectable stage 3C/3D/4M1 cutaneous metastatic malignant melanoma that have failed to respond to systemic checkpoint and localized intra-tumoral immunotherapy. The study will involve up to 10 participants with stable or progressive cutaneous and/or subcutaneous skin lesions (Immune Stable Disease (iSD) or Immune Confirmed/Unconfirmed Progressive Disease (iCPD/iUPD)). GNRs, when administered via intra-tumoral injection and activated by NIR light, generate localized heat through a process called THT. This approach selectively targets tumor cells while minimizing damage to surrounding healthy tissue. In this study, 10 participants will receive two THT treatments spaced 7 days apart. The primary objective of this study is to assess the safety and tolerability of THT treatment.
