Received at least 2 prior lines of systemic therapies and not eligible to receive additional standard of care therapies. 4. An Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤ 2 at screening. 5. Adequate organ function within 3 days of the first dose of study intervention. 6. A negative blood pregnancy test within 7 days prior to first dose of study intervention (for women of childbearing potential). Exclusion Criteria: 1. Receiving an investigational product or participating in any other type of medical research judged not to be compatible with this study. 2. Grade \> 1 neuropathy 3. History of interstitial lung disease (ILD)/pneumonitis requiring treatment or any evidence of active ILD/pneumonitis. 4. Use of: 1. Chemotherapy, radiotherapy, small molecule, investigational, and biologic agents (including CD79b-directed agents) within 28 days (or at least 5 half-lives, whichever is shorter), prior to the first dose of the study intervention. 2. Any live or live-attenuated vaccine within 28 days before the first dose of the study intervention. 5.
