A Phase 1/2 Open-Label Study Evaluating the Safety and Efficacy of ST-067 in Combination With CD19-Directed CAR T-Cell Therapy in Patients With Relapsed/Refractory (R/R) Large B-Cell Lymphoma (LBCL)
This phase I/II trial tests the safety, side effects, and best dose/regimen of ST-067 in combination with CD19-directed chimeric antigen receptor (CAR) T-cell therapy (liso-cel) and how well it works in treating patients with large B-cell lymphoma (LBCL) that has come back after a period of improvement (recurrent) or LBCL that has not responded to previous treatment (refractory). ST-067 is an engineered variant of the human cytokine interleukin-18 that may help the immune system kill cancer cells. Lisocabtagene maraleucel (liso-cel) is an autologous CAR T-cell therapy prepared using the person's own immune system (a group of cells, tissues, and organs that protect the body from attack by bacteria, viruses, and cancer cells) to fight the cancer. Giving ST-067 in combination with liso-cel may better treat patients with relapsed/refractory LBCL.
• Male or female \>= 18 years of age at the time of consent
• Patients with LBCL (including diffuse large B-cell lymphoma \[DLBCL\] not otherwise specified \[including DLBCL arising from indolent lymphoma\], high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B) with at least 2 lines of systemic therapy and an Food and Drug Administration (FDA)-approved indication for treatment with liso-cel

• Adequate cardiac function, defined as left ventricular ejection fraction (LVEF) \>= 40% as assessed by echocardiogram or multiple uptake gated acquisition (MUGA)
• Women of reproductive potential (defined as all women physiologically capable of becoming pregnant) must agree to use suitable methods of contraception for at least 30 days after the last dose of study therapy (ST-067)
