Brief 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.

Conditions

Malignant Melanoma Stage III

Keywords

Outcome Measures

Primary Outcomes (2)

• Safety of patients as measured by the adherence to the timelines in the study protocol

  A treatment arm will be declared as not safe if 8/10 patients develop gr 3-4 adverse events or if 2/10 patients develop longlasting (\>6 months) gr 3-4 adverse events.

  6 months

• Feasability of patients as measured by the adherence to the timelines in the study protocol

  A treatment arm will be declared as not feasible if 2/5 or 4/10 patients cannot adhere to the planned time of surgery (week 6 +/- 1 week) due to treatment related adverse events.

  6 weeks

Secondary Outcomes (15)

• Pathologic response rates (pPR, near-pCR, and pCR).

  At 6 weeks

• Frequency of treatment-related toxicities as measured according to CTCAE 5.0.

  At 6 weeks

• Radiologic response rate according to RECIST 1.1 criteria

  At 6 weeks

• Relapse Free Survival (RFS)

  Up to 3 years after treatment

• RNA signatures associated with pathologic response and RFS for each arm (by RNAseq and NanoString gene expression analysis).

  Up to 3 years after treatment

Drug: Domatinostat; Drug: Nivolumab

C

EXPERIMENTAL

For IFN-gamma low patients: patients will receive pre-surgically 2 courses nivolumab 240 mg (q3weeks) + domatinostat 200 mg BID, on days 1-14 (q3weeks)

Drug: Domatinostat; Drug: Nivolumab

D

EXPERIMENTAL

For IFN-gamma low patients: patients will receive pre-surgically 2 courses nivolumab 240 mg (q3weeks) + ipilimumab 80 mg (q3weeks) + domatinostat. Patients in arm D will start with once daily (OD) dosing scheme of domatinostat 200 mg, on days 1-14 (q3weeks). Based on safety data of the first 5 patients in this arm, the next patients will be treated with either a higher dosing scheme (200 mg BID, days 1-14, q3weeks), a lower dosing scheme (100 mg OD, days 1-14, q3weeks), or the same dosing scheme (200 mg OD, days 1-14, q3weeks).

Drug: Domatinostat; Drug: Nivolumab; Drug: Ipilimumab

Interventions

Domatinostat DRUG

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).

• Patient willing to undergo quadruple tumor biopsies and extra blood withdrawal during screening, week 3 and in case of relapse.
• The biopsies at screening should contain at least 30% tumor cells in order to get a reliable IFN-gamma signature
• No immunosuppressive medications within 6 months prior trial registration.

• 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.

• History of allergy to study drug components;
• History of severe hypersensitivity reaction to any monoclonal antibody.
