Brief summary:
This is a Phase 2a, open-label, parallel group, partly randomized dose escalation trial to assess the safety and efficacy of a low dose, an intermediate dose, and high dose MSB0010445 given by intravenous infusion to subjects with advanced (unresectable or metastatic) melanoma in combination with stereotactic body radiation therapy (SBRT).

Detailed description:

Arms:
arm 1: None arm 2: None arm 3: None arm 4: None

Interventions: intervention 1: MSB0010445 (0.3 milligram per kilogram [mg/kg]) intervention 2: MSB0010445 (1.0 mg/kg) intervention 3: MSB0010445 (1.8 mg/kg) intervention 4: MSB0010445 (2.4 mg/kg) intervention 5: Stereotactic Body Radiation Therapy (SBRT)
Intervention descriptions: intervention 1: MSB0010445 will be administered at a single dose of 0.3 mg/kg as intravenous (IV) infusion over approximately 1 hour every 3 weeks (q3w) for the first 12 Weeks as a part of induction phase followed by maintenance dose of 0.3 mg/kg drug every three weeks until significant clinical progression, occurrence of unacceptable toxicity, or withdrawal of consent. The first administration of MSB0010445 will be performed 3 days after the last dose of Stereotactic Body Radiation Therapy (SBRT) to the targeted reference lesion. intervention 2: MSB0010445 will be administered at a single dose of 1.0 mg/kg as IV infusion over approximately 1 hour q3w for the first 12 Weeks as a part of induction phase followed by maintenance dose of 0.3 mg/kg drug every three weeks until significant clinical progression, occurrence of unacceptable toxicity, or withdrawal of consent. The first administration of MSB0010445 will be performed 3 days after the last dose of SBRT to the targeted reference lesion. intervention 3: MSB0010445 will be administered at a single dose of 1.8 mg/kg as IV infusion over approximately 1 hour q3w for the first 12 Weeks as a part of induction phase followed by maintenance dose of 0.3 mg/kg drug every three weeks until significant clinical progression, occurrence of unacceptable toxicity, or withdrawal of consent. The first administration of MSB0010445 will be performed 3 days after the last dose of SBRT to the targeted reference lesion. intervention 4: MSB0010445 will be administered at a single dose of 2.4 mg/kg as IV infusion over approximately 1 hour q3w for the first 12 Weeks as a part of induction phase followed by maintenance dose of 0.3 mg/kg drug every three weeks until significant clinical progression, occurrence of unacceptable toxicity, or withdrawal of consent. The first administration of MSB0010445 will be performed 3 days after the last dose of SBRT to the targeted reference lesion. intervention 5: SBRT will be administered using a dose and schedule recommended based upon the data showing the best abscopal effect using multiple fractions if one site will be targeted subject received 3 fractions (1 per day) of 8 Gray (Gy) each (total: 24 Gy). If the target lesion will be located in the thorax, the maximum total dose administered will be 18 Gy (3 x 6 Gy).
