Brief Summary:
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 treatmentampampamp39s 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

Detailed Description:
This is a single arm single center open-label phase II study to assess the effect of neoadjuvant LTX-315 in combination with pembrolizumab in patients with clinically detectable and resectable stage III-IV melanoma
Clinically detectable fully resectable stage III or oligometastatic IV melanoma can be cured with surgery but has a very high risk of local or systemic recurrence The risk of recurrence can be significantly reduced by adjuvant treatment with a PD-1 inhibitor Due to the mode of action of PD-1 inhibitors stimulating tumor reactive T cells there is reason to believe that their effect is enhanced if given before definitive surgery and removal of tumor reactive T cells in the tumor microenvironment Indeed it was recently shown that the effect is greatly improved if three doses of pembrolizumab are administered prior to surgery neoadjuvant followed by 15 doses in the adjuvant setting compared to giving 18 doses adjuvant
Several studies have shown that pathologic complete response pCR after neoadjuvant treatment correlates with recurrence-free survival RFS The pCR rate neoadjuvant pembrolizumab is only modest 20 and for 8 of the patients disease progression in the neoadjuvant phase precludes the planned surgery
LTX-315 is an oncolytic peptide generated from a host defense peptide and has both a direct killing activity and immunomodulatory properties By inducing cell lysis and immunogenic cell death LTX-315 can lead to increased T-cell infiltration broadened repertoire of tumor antigens and increased diversity of T-cell clones and thus has the potential to enhance the effect of pembrolizumab Furthermore the addition of LTX-315 to neoadjuvant pembrolizumab can lower risk of disease progression precluding surgery
