ST-067 in Combination With CD19-Directed CAR T-Cell Therapy (Liso-cel) in Relapsed/Refractory Large B-Cell Lymphoma

Summary

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.

* 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)
* Males who have partners of reproductive potential must agree to use an effective barrier contraceptive method for at least 90 days after the last dose of study therapy (ST-067)
* Ability to understand and provide informed consent
* Able and willing to comply with study visit schedule and procedures, including tumor biopsy where feasible and with acceptable risk

Exclusion Criteria:

* Planned use of out-of-specification liso-cel product
* History of another malignancy. The following are exceptions to this criterion:

  * Adequately treated basal cell or squamous cell carcinoma of the skin.
  * In situ prostate, ductal breast carcinoma breast, and cervical carcinoma.
  * Adequately treated papillary, noninvasive bladder cancer.
  * Other adequately treated stage 1 or 2 cancers currently in complete remission.
  * Any other cancer that has been in remission for \>= 2 years
* Planned use of therapeutic doses of corticosteroids (\> 20 mg/day prednisone or equivalent) or other systemic immunosuppression within 7 days prior to leukapheresis or within 72 hours prior to liso-cel infusion. Topical and/or inhaled steroids are permitted
* Prior treatment with any CD19 CAR T-cell therapy
* For allogeneic hematopoietic cell transplant recipients, active graft versus host disease (GVHD) and/or systemic GVHD therapy within 30 days prior to planned leukapheresis
* Known active hepatitis B (detectable hepatitis B deoxyribonucleic acid \[DNA\]) or hepatitis C (detectable hepatitis C ribonucleic acid \[RNA\])
* Known human immunodeficiency virus (HIV) infection
* Pregnant or breastfeeding women
* Prior treatment with any IL-1 or IL-18 agonist and/or biosimilar agents, or an investigational agent within 4 weeks or 5 half-lives, whichever is shorter, prior to start of lymphodepletion
* Active autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., ulcerative colitis, Crohn's disease\], celiac disease, or other serious chronic gastrointestinal conditions associated with diarrhea, autoimmune vasculitis, systemic lupus erythematosus, Wegener syndrome \[granulomatosis with polyangiitis\], myasthenia gravis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.) requiring immunosuppressive therapy. The following are exceptions to this criterion:

  * Vitiligo.
  * Alopecia.
  * Hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement.
  * Type 1 diabetes mellitus.
  * Psoriasis not requiring systemic treatment.
  * Conditions considered to be low risk of serious deterioration by the PI
* History of any one of the following cardiovascular conditions within the past 6 months, unless clearance by a cardiologist is obtained: class III or IV heart failure as defined by the New York Heart Association (NYHA), cardiac angioplasty or stenting, myocardial infarction, or unstable angina. History of other clinically significant cardiac disease that, in the opinion of the PI or designee, is a contraindication to study treatment is also excluded
* Significant electrocardiogram (ECG) abnormalities, including unstable cardiac arrhythmia requiring medication, second-degree atrioventricular (AV) block type II, third-degree AV block, \>= grade 2 bradycardia, or QT interval corrected using Fridericia's formula \> 500 ms irrespective of gender
* History or presence of clinically relevant central nervous system (CNS) pathology, such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, or psychosis that in the opinion of the PI is a contraindication to study treatment.
