Clinical Trial Summary

This is an open-label, randomized, multi-site, Phase II, interventional trial designed to evaluate the efficacy, tolerability, and safety of BNT111 + cemiplimab in anti-programmed death protein 1 (PD-1)/anti-programmed death ligand 1 (PD-L1)-refractory/relapsed patients with unresectable Stage III or IV melanoma. The contributions of BNT111 and cemiplimab will be delineated in single agent calibrator arms. Patients will be randomized in a 2:1:1 ratio to Arm 1 (BNT111 + cemiplimab) and calibrator Arm 2 (BNT111 monotherapy), and Arm 3 (cemiplimab monotherapy). Patients in single agent calibrator arms (Arms 2 and 3), who experience centrally verified disease progression under single agent treatment, may be offered addition of the other compound to the ongoing treatment after re-consent.

• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Patients must sign the written informed consent form (ICF) before any screening procedure.

• Patients must be aged = 18 years on the date of signing the informed consent.

• Patients must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests, and other requirements of the trial.

• Patients must have histologically confirmed unresectable Stage III or IV (metastatic) cutaneous melanoma and measurable disease by RECIST 1.1.

• Patients must have confirmed disease progression on/after an approved anti-PD-1/PD-L1 regimen for melanoma as defined by RECIST 1.1.

1. Previous exposure to approved anti-PD-1/PD-L1 containing regimen for at least 12 consecutive weeks and

2. Current radiological progression to be confirmed by two scans 4 to 12 weeks apart. If progression is accompanied by new symptoms, or deterioration of performance status not attributed to toxicity, one scan is sufficient and

3. Inclusion into this trial must be within 6 months of confirmation of disease progression on anti-PD-1/PD-L1 treatment, regardless of any intervening therapy.

• Patients should have received at least one but no more than five lines of prior therapy for advanced disease.

• Patients must be able to tolerate additional anti-PD-1/PD-L1 therapy (i.e., did not permanently discontinue anti-PD-1/PD-L1 therapy due to toxicity).

• Patients must have known B-Raf proto-oncogene (BRAF) mutation status.

• Patients with BRAF V600-positive tumor(s) should have received prior treatment with a BRAF inhibitor (alone or in combination with a mitogen-activated protein kinase kinase [MEK] inhibitor).

• Note: Considering the possible negative impact of a prior BRAF/MEK therapy on immune system targeting therapies, patients with BRAF V600-positive tumors with no clinically significant tumor-related symptoms or evidence of rapid PD may be eligible for participation. This should be based on investigator assessment AND provided they are ineligible for, intolerant to, or have refused BRAF V600 mutation targeted therapy after receiving the information on possible other therapies including BRAF/MEK inhibitor-based therapy during the informed consent process.

• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) = 1.

• Adequate bone marrow function, as defined by hematological parameters (as defined in the protocol).

• Patients must have serum lactate dehydrogenase (LDH) = upper limit of normal (ULN).

• Patient should have adequate hepatic function, as defined in the protocol.

• Patient should have adequate kidney function, assessed by the estimated glomerular filtration rate (eGFR) = 30 mL/min using the chronic kidney disease epidemiology collaboration (CKD-EPI) equation.

• Patient should be stable with adequate coagulation, as defined in the protocol.

• Patients must provide the following biopsy samples:

1. All patients: must provide a tumor tissue sample (formalin fixed paraffin-embedded [FFPE] blocks/slides) from a fresh biopsy collected before Visit C1D1, or archival tissue. The archival tissue can be an FFPE block (not older than 3 years) or freshly cut slides (special storage conditions and immediate shipment to specialty lab are required), preferably derived from advanced disease stage.

2. Patients at selected trial sites: After additional consent, patients must be amenable to pre-treatment and on-treatment peripheral blood mononuclear cell (PBMC) sampling and optional biopsy. If amenable, patients should provide a PBMC sample and optionally a biopsy which contains tumor tissue after failure/stop of last prior trial treatment.

• Women of childbearing potential (WOCBP) must have a negative serum (beta-human chorionic gonadotropin [beta-hCG]) at screening. Patients that are postmenopausal or permanently sterilized can be considered as not having reproductive potential. Female patients of reproductive potential must agree to use highly effective contraception during and for 6 months after the last trial drug administration.

• WOCBP must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during trial starting at screening, during the trial and for 6 months after receiving the last trial treatment.

• A man who is sexually active with a WOCBP and has not had a vasectomy must agree to use a barrier method of birth control, e.g., either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository, and all men must also not donate sperm during the trial and for 6 months after receiving the last trial treatment.
