A Trial of LNS8801 With or Without Pembrolizumab in Patients With Refractory Melanoma

The goal of this clinical trial is to understand if a new drug called LNS8801 can safely treat patients with melanoma. The primary question to be answered is what is the average length of time during which melanoma does not grow or spread after starting treatment with LNS8801? Researchers will compare LNS8801 taken alone or LNS8801 taken together with another drug called pembrolizumab to other therapies as decided by the treating doctor. 135 patients will be randomly (like flipping a coin) placed in 3 treatment groups. In the first group (LNS8801 only) - Patients will take 125mg tablet of LNS8801 by mouth once per day every day for up to 2 years. In the second group (LNS8801 + pembrolizumab) - Patients will take 125mg tablet of LNS8801 by mouth once per day plus 200 mg of pembrolizumab by IV infusion once every 3 weeks for up to 2 years. In the third group, called Physician's Choice (PC), patients will receive chemotherapy (dacarbazine or temozolomide) or immunotherapy (pembrolizumab, nivolumab/relatlimab or nivolumab/ipilimumab) as determined by their treating physician. How often the patient visits the clinic visits will depend on the treatment group. Besides returning to the clinic for treatment, the patient will undergo periodic safety assessments and other required study procedures such as imaging assessments.

NeoLIPA: Neoadjuvant LTX-315 in Combination with Pembrolizumab in Resectable Stage III/IV Melanoma

This clinical trial aims to evaluate the effectiveness of a new treatment approach for patients with stage III or IV melanoma that has spread to other parts of the body but can still be surgically removed. The study combines two treatments: LTX-315 and pembrolizumab. Melanoma that has spread to other parts of the body can often be treated with surgery. Despite surgery, there is a high risk of the cancer coming back. Pembrolizumab, an immune checkpoint inhibitor, can reduce this risk when given after surgery. Recent studies have shown that giving pembrolizumab before surgery, along with post-surgery treatment, might be more effective than giving it only after surgery. However, many patients still experience cancer recurrence. Combining pembrolizumab with LTX-315, which triggers a different immune response, might improve the treatment\'s effectiveness and reduce the risk of cancer progression before surgery. This is an open-label Phase II study, meaning both the researchers and participants will know which treatments are being given. The study will be conducted at a single center and will involve about 27 participants. They will receive LTX-315 and pembrolizumab before their planned surgery to see if this combination could be more effective than pembrolizumab alone. The primary goal is to assess the tumors response to the neoadjuvant (pre-surgery) treatment, specifically looking at the rate of pathological complete response (pCR), where no cancer is detected in the removed tumor tissue.
