Treatment: Drugs - Daratumumab

Experimental: Dose Exploration Phase: Forimtamig (Dose 1) + Carfilzomib - Participants will receive Dose 1 of forimtamig, subcutaneous (SC) injection in combination with carfilzomib, intravenous (IV) infusion until disease progression.

Experimental: Dose Exploration Phase: Forimtamig (Dose 2) + Carfilzomib - Participants will receive Dose 2 of forimtamig, SC injection in combination with carfilzomib, IV infusion until disease progression.

Experimental: Dose Exploration Phase: Forimtamig (Dose 3) + Carfilzomib - Participants will receive Dose 3 of forimtamig, SC injection in combination with carfilzomib, IV infusion until disease progression.

Experimental: Dose Exploration Phase: Forimtamig (Dose 1) + Daratumumab - Participants will receive Dose 1 of forimtamig, SC injection in combination with daratumumab, SC injection until disease progression.

Experimental: Dose Exploration Phase: Forimtamig (Dose 2) + Daratumumab - Participants will receive Dose 2 of forimtamig, SC injection in combination with daratumumab, SC injection until disease progression.

Experimental: Dose Exploration Phase: Forimtamig (Dose 3) + Daratumumab - Participants will receive Dose 3 of forimtamig, SC injection in combination with daratumumab, SC injection until disease progression.

Experimental: Dose Expansion Phase: Forimtamig - Participants will receive forimtamig, SC injection at a fixed dose determined during dose exploration phase until disease progression or completion of 12 months of treatment, whichever occurs first.

Experimental: Dose Expansion Phase: Forimtamig + Carfilzomib - Participants will receive forimtamig, SC injection at a fixed dose determined during dose exploration phase in combination with carfilzomib, IV infusion until disease progression.

Experimental: Dose Expansion Phase: Forimtamig + Daratumumab - Participants will receive forimtamig, SC injection at a fixed dose determined during dose exploration phase in combination with daratumumab, SC injection until disease progression.


Treatment: Drugs: Forimtamig
Forimtamig will be administered SC at different doses during dose exploration phase. Forimtamig will be administered at a fixed dose determined during dose exploration phase in dose expansion phase.

Treatment: Drugs: Carfilzomib
Carfilzomib will be administered via IV infusion in combination with forimtamig.

Treatment: Drugs: Daratumumab
Daratumumab will be administered via SC injection in combination with forimtamig.

Summary
Brief summary
The purpose of this study is to evaluate the safety, tolerability, and preliminary anti-tumor
activity of forimtamig when administered alone or in combination with carfilzomib or
daratumumab or other combination partners in participants with relapsed or refractory
multiple myeloma (r/r MM). The study consists of two phases: a dose exploration phase and a
dose-expansion phase.
