Summary
Uveal melanoma (UM) is a rare type of melanoma, with an incidence of 4.4 cases per million in Europe each year. During recent years, different treatment approaches have been tested in patients with metastatic UM. Responses have been reported primarily with localized treatment in patients with a limited number of liver metastases. In cases of diffuse liver involvement or extrahepatic disease, systemic therapies are justified. However, to date, systemic therapies such as targeted therapy with selumetinib or conventional chemotherapy have failed in metastatic UM.
Neo-TB is a Phase II, single arm, multicentre clinical trial designed to evaluate efficacy and safety of tebentafusp used as a single agent in patients with metastatic uveal melanoma with resectable / potentially resectable liver metastasis and absence of extrahepatic disease.
The main questions it aims to answer are:
1. Which is the capacity of tebentafusp used as a single agent to generate pathological complete response (pCR) in patients with metastatic uveal melanoma with resectable liver metastasis and absence of extrahepatic disease.
2. Which is the efficacy of tebentafusp used as a single agent to maintain disease control and delay relapse / progression.
3. Which is the safety of tebentafusp used as a single agent in metastatic uveal melanoma.
The main hypothesis is that neoadjuvant treatment with Tebentafusp could achieve 20% pathological complete response (pCR) in patients with metastatic uveal melanoma with resectable/potentially resectable liver metastasis and absence of extrahepatic disease. It is assumed that untreated patients would not present a pCR (response rate of 1%).
