Clinical Trial Summary

This trial is a first-in-human drug combination with the first-in-class alkylating histone deacetylase inhibition (HDACi) fusion molecule Tinostamustine (EDO-S101) and the anti-PD-1 monoclonal antibody Nivolumab in patients with refractory, locally advanced or metastatic melanoma.

Description:

Despite improvement of systemic treatment in patients with advanced melanoma, there is still unmet medical need in this group of patients. Tinostamustine is a medication without marketing authorization, while Nivolumab is approved for several tumor entities. The primary objective of this trial is to assesses the safety, tolerability and recommended dose of Tinostamustine in combination with Nivolumab in patients with advanced melanoma.Secondary objectives of this trial in patients with advanced solid tumors are to assess the preliminary efficacy of Tinostamustine when given in combination with Nivolumab and to characterize potential predictive biomarkers of the combination treatment of Tinostamustine and Nivolumab. The trial includeds patients with either histologically or cytologically confirmed inoperable stage III or metastatic stage IV melanoma with an indication for the regular systemic treatment with Nivolumab and a maximum of 1 prior systemic palliative line of treatment.

Eligibility

Inclusion Criteria:

• Written informed consent

• Patients with either histologically or cytologically confirmed inoperable stage III or metastatic stage IV melanoma

• Indication for the regular systemic treatment with the anti-PD-1 monoclonal antibody Nivolumab monotherapy

• Patient received a maximum of 1 prior systemic palliative line of treatment

• ECOG =2

• Patients with brain metastases must have undergone definitive treatment (surgery or radiotherapy) at least 2 weeks prior to starting study drug and be documented as having stable disease by imaging

• Adequate bone marrow, renal and hepatic function

• Adequate contraception

Exclusion Criteria:

• Prior treatment with a PD-(L)1 targeted monoclonal antibody

• Patients who have received systemic treatments or radiotherapy within 2 weeks prior to starting study drug

• Concomittant treatment with systemic steroids at a daily dose equivalent to =10mg of prednisone, or concomittant treatment with immunosuppressive drugs such as methotrexate

• Patients with a prior malignancy are excluded (except non-melanoma skin cancers, and in situ cancers such as the following: bladder, colon,cervical/dysplasia, melanoma, or breast). Patients with other second malignancies diagnosed more than 2 years ago who have received therapy with curative intent with no evidence of disease during the interval who are considered by the Investigator to present a low risk for recurrence will be eligible.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and dose-limiting toxicity	Dose limiting toxicity defined as any of the following AEs (according to CTCAE v 4.03) occurring during the first 42 days of study treatment for each study patient of the safety part of the trial, and regarded to be related (possibly, probably or definitely) to Tinostamustine: CTC °4 neutropenia during = 5 days; Febrile neutropenia; CTC °4 thrombocytopenia or CTC° 3 thrombocytopenia with bleeding; Any other = CTC °4 hematological AE; = CTC °3 AST or ALT elevations for >7 days, or CTC °4 AST/ALT elevations for any duration; = CTC °3 nausea, vomiting or diarrhea despite appropriate pre-medication; Any other = CTC °3 non-hematological study-treatment-related AE, excluding alopecia; = CTC °3 uveitis, pneumonitis, bronchospasm, neurological toxicity, hypersensi-tivity reactions or infusion reactions that result in discontinuation of study treat-ment; Any study treatment-related AE that results in a delay of the administration of Tinostamustine of at least 4 weeks	at 6 weeks
Secondary	Overall safety profile of the tinostamustine/nivolumab drug combination	All adverse events (AE) including laboratory safety parameters according to CTCAE v.4.03	during a maximum 2 years of study treatment plus 100 days thereafter (3 years)
Secondary	Radiological response	Objective tumor response according to RECIST 1.1 and iRECIST	every 8 weeks until progressive disease or end of study (5 years)
Secondary	Progression-free survival	Progression-free survival (PFS, iPFS), defined as the time between registration to the study and the time of disease progression according to RECIST v.1.1 and iRECIST or death of the patient, whatever occurs first	through study completion (5 years)
Secondary	Overall survival	Overall survival (OS) from registration of study participation	through study completion (5 years)
