Clinical Trial Summary

DONIMI is a phase 1b trial testing the combination of domatinostat + nivolumab or nivolumab monotherapy in IFN-gamma signature high patients and of domatinostat + nivolumab or domatinostat + nivolumab + ipilimumab in IFN-gamma signature low patients with de-novo or recurrent macroscopic stage III cutaneous or unknown primary melanoma.

The trial will include 45 stage III cutaneous or unknown primary melanoma patients with RECIST 1.1 measurable de-novo or recurrent disease (short axis lymph node metastasis ≥1.5cm).

NanoString IFN-gamma signature high patients will be randomized to be treated pre-surgically for 6 weeks with nivolumab (arm A; 10 patients) or domatinostat + nivolumab (arm B; 10 patients).

IFN-gamma signature low patients will be randomized to be treated pre-surgically for 6 weeks with domatinostat + nivolumab (arm C; 10 patients) or domatinostat + nivolumab + ipilimumab (arm D; 15 patients). Patients will be stratified according to center.

Post-surgery (starting at week 12), the patients will start with adjuvant nivolumab or pembrolizumab for 52 weeks according to institute's standard. BRAF V600E/K mutation positive patients with no pathologic response after neoadjuvant therapy may also receive adjuvant BRAF + MEK inhibition if commercially available and according to the patient's and the treating physician's decision.

Follow-up after the adjuvant therapy will be for 2 years, according to the institutes' standard.

Toxicity and pathologic response rates will be descriptive. In case of 2/5 or 4/10 patients not undergoing their lymph node dissection at week 6 +/- 1 week due to treatment related toxicity, this arm will be declared unfeasible.

• Patient is capable of understanding and complying with the protocol requirements and has signed the Informed Consent document.

Exclusion Criteria:

Distantly metastasized melanoma

• Uveal or mucosal melanoma.

• History of in-transit metastases within the last 6 months.

• No measurable lymph node lesion according to RECIST 1.1.

• Subjects with any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications, except for subjects with vitiligo or resolved childhood asthma/atopy.

• Patients with any active gastrointestinal disorder that could interfere with the absorption of domatinostat (as per judgement of the investigator), such as ulcerative colitis, Crohn's disease, diabetic gastroparesis, or other syndromes characterized by malabsorption.

• Prior CTLA-4 or PD-1/PD-L1 targeting immunotherapy.

• Prior targeted therapy targeting BRAF and/or MEK.

• Prior radiotherapy.

• Patients will be excluded if they test positive for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody), indicating acute or chronic infection; if treated and being at least one year free from HCV patients are allowed to participate.

• Patients will be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).

• Allergies and Adverse Drug Reaction:

• History of allergy to study drug components;

• History of severe hypersensitivity reaction to any monoclonal antibody.

• Underlying medical conditions that, in the Investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of toxicity or adverse events.

• Patients with a marked baseline prolongation of QT/QTc interval, e.g., repeated demonstration of a QTc interval >450 msec (Grade 1 NCI-CTCAE); Long-QT-Syndrome) and patients receiving agents known to prolong the QT interval and known risk of Torsades de Pointes.

• Patients with significant current cardiovascular disease including:

• Unstable angina pectoris within 6 months prior to screening

• Uncontrolled hypertension

• Congestive heart failure (New York Heart Association (NYHA) Class III or IV) related to primary cardiac disease

• Conditions requiring anti-arrhythmic therapy (patients with status post pace maker implantation can be included)

• Symptomatic ischemic or severe valvular heart disease, or a myocardial infarction within 6 months prior to the trial entry

• Women who are pregnant or lactating

• Use of other investigational drugs before study drug administration 30 days and 5 half-times before trial registration.

Intervention

Drug:
• Domatinostat
Patients in arm B and C will receive domatinostat 200 mg BID, days 1-14 q3weeks. Patients in arm D will start with once daily (OD) dosing scheme of domatinostat 200mg, d1-14 q3wks. Based on safety data of the first 5 patients in this arm, the next patients will be treated with either a higher dosing scheme (200mg BID, d1-14, q3wks), a lower dosing scheme (100mg OD, d1-14, q3wks) or the same dosing scheme (200mg OD, d1-14, q3wks).
• Nivolumab
2 courses nivolumab 240 mg q3weeks
• Ipilimumab
2 courses ipilimumab 80 mg q3weeks
