Description of intervention(s) / exposure
Treatment: Drugs - BTCT4465A (Mosunetuzumab) IV
Treatment: Drugs - Atezolizumab
Treatment: Drugs - BTCT4465A (Mosunetuzumab) SC

Experimental: Dose Escalation - Participants will receive BTCT4465A (Mosunetuzumab) via intravenous (IV) infusion or subcutaneous (SC) injection as a single-agent or in combination with atezolizumab. Dose escalation will be guided by the observed incidence of DLTs at each dose level.

Experimental: Dose Expansion - Participants will receive BTCT4465A (Mosunetuzumab) as a single-agent or in combination with atezolizumab.


Treatment: Drugs: BTCT4465A (Mosunetuzumab) IV
Participants with B-cell NHL and CLL will receive BTCT4465A (Mosunetuzumab) via IV infusion.

Treatment: Drugs: Atezolizumab
Participants assigned to an atezolizumab combination group will receive atezolizumab 1200 mg administered as an IV infusion in combination with BTCT4465A (Mosunetuzumab).

Treatment: Drugs: BTCT4465A (Mosunetuzumab) SC
Participants with B-cell NHL and CLL will receive BTCT4465A (Mosunetuzumab) via SC injection.
