An Open-Label, First-in-Human Phase 1/2, Dose-Escalation and Dose-Expansion/ Combination Therapy Study to Investigate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of SB-4826 as a Single Agent in Adult Participants With Locally Advanced or Metastatic Solid Tumors or Non-Hodgkin Lymphomas and in Combination With Rituximab in Adult Participants With Non-Hodgkin Lymphomas.
The goal of this clinical trial is to learn what dose of the drug SB-4826 can be given safely in patients with solid tumors and non-Hodgkin lymphomas. This drug will be used alone in patients with solid tumors, and will be used alone or in combination with rituximab in patients with non-Hodgkin lymphomas. The main questions this clinical trial aims to answer are: What is the maximum dose of SB-4826 that can be used safely in patients with solid tumors and non-Hodgkin lymphomas, and will it work? How does SB-4826 work in people with cancer? How is SB-4826 absorbed, broken down, and excreted by the body? Participants will: Take drug SB-4826 every other day for up to 1 year; keep a diary of when they take SB-4826 at home; visit the clinic for checkups, tests, and fill out study questionnaires.
