A Study of TQB3820 in Patients With Hematological Malignancies

A Phase I Study to Evaluate the Tolerability and Pharmacokinetics of TQB3820 in Relapsed or Refractory Multiple Myeloma (R/R MM) or Relapsed or Refractory Indolent B-cell Non-Hodgkin's Lymphoma (R/R B-NHL)

TQB3820 is a novel cereblon-modulating agent. Upon binding to cereblon, a substrate receptor in the cullin4 E3 ligase complex, TQB3820 promotes recruitment, ubiquitination, and subsequent proteasomal degradation of the hematopoietic transcription factors Ikaros (IKZF1) and Aiolos (IKZF3). Modulation of Aiolos and Ikaros expression has the potential to correct multiple aspects of the immune dysregulation mediated by B cells.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: TQB3820 tablets; TQB3820 tablets are administrated orally on Days 1-28 of each 28-day treatment cycle. Dose escalation of TQB3820 will be based on evaluation of clinical safety and tolerability and guided by accumulating PK data.	Drug: TQB3820 tablets; TQB3820 is a novel cereblon-modulating agent.
