A clinical study of Tebentafusp alone or in combination with Pembrolizumab in suitable participants with pre-treated advanced melanoma.
Descrizione riassuntiva dello studio
Tebentafusp is approved for the treatment of uveal melanoma (melanoma that starts in the eye). In this study, Tebentafusp is an experimental medication, meaning it has not yet been approved by a governmental authority for the treatment of the melanoma types being studied in this trial. The investigational drug helps T-cells (part of the body's immune system) bind to cancer cells that express the markers "HLA-A*02:01" and "gp100" and attack them. This is an open-label study, meaning you will know which treatment you will receive. The study consists of 3 treatment arms. Participants will be assigned equally to the treatment arms: In Arm A, treatment will be with Tebentafusp as monotherapy (single drug). In Arm B, Tebentafusp will be given in combination with Pembrolizumab, another approved medication. Arm C is a choice of other suitable treatments made by the investigator. Options include other standard drug treatments, best supportive care, and other clinical trials for which you would meet the inclusion criteria (except for studies sponsored by Immunocore). The main goal of the study is to investigate whether Tebentafusp improves survival compared to the therapy chosen by the investigator.

Intervento studiato
The study is divided into Phase II and Phase III:
In Phase II of the study, approximately 120 participants will be enrolled and randomly assigned to one of the treatment arms based on a set of predefined criteria. The allocation will be 1:1:1, meaning approximately 40 participants will be enrolled in each treatment arm. This approach aims to ensure the homogeneity of the treatment groups.
After the 120th patient is assigned in Phase II, Phase III of the study will begin. Participants will again be randomly assigned to treatment groups. However, these treatment groups may change based on the data observed in Phase II of the study. In Phase III of this study, approximately 510 participants are expected to be enrolled.
Each phase of this clinical study consists of 3 main sections: pre-screening/screening section, drug administration and treatment section, and follow-up section regarding survival. These sections will be described in more detail below. Pre-screening/screening section: All participants will take part in this section. This section begins after you have signed the patient information and consent form, in which you confirm that you understand the study and wish to participate. In this section, the investigator will review your medical records and examine you to ensure that this study is appropriate for you and that you meet the criteria for participation. As part of this process, various blood tests and radiological examinations (CT, MRI, etc.) will be performed. Additionally, a biopsy of your tumor tissue will be required unless an archived sample is available. After these examinations are completed, you will be randomly assigned to one of the treatment groups in the drug administration and treatment section of the study.
Drug administration and treatment section: Only participants in Arm A and Arm B of the study will undergo a treatment regimen with Tebentafusp (either Tebentafusp alone or Tebentafusp in combination with Pembrolizumab). Participants assigned to Arm C will receive a treatment determined by their treatment team. This may include another clinical trial or local standard treatments. During this time, all participants must attend the scheduled study visits for drug treatment and assessment. At certain times and intervals, as well as depending on the assigned treatment arm, additional blood samples and radiological examinations will be performed. Participants will remain in this section until disease progression occurs or further treatment is no longer possible due to safety or tolerability concerns. The maximum treatment duration is 2 years.
Follow-up section regarding survival: A follow-up regarding survival will be conducted on all participants. The follow-up will continue until the participants' death to determine whether treatment with Tebentafusp prolongs survival. During this section, participants will receive other suitable therapies, both approved and experimental.
