Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma | Biological: IOV-2001 Drug: Low dose IL-2 Drug: High dose IL-2 Drug: IL-2 | Phase 1 Phase 2 |
This study involves patients receiving nonmyeloablative (NMA) lymphocyte depleting (LD) preparative regimen prior to infusion of IOV-2001 followed by IL-2 administration.
In Phase 1, patients meeting the eligibility criteria will be enrolled and will receive treatment with IOV-2001 followed by low dose IL-2 or high dose IL-2.
After completion of Phase 1, the recommended Phase 2 dose (RP2D) will be evaluated in selected patient cohorts defined in the Phase 2 part of the study.

Ages Eligible for Study: | 18 Years to 70 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |

Exclusion Criteria:
- Patients who have received an organ allograft or prior cell transfer therapy within 20 years.
- Patients with known or suspected transformed disease (ie, Richter's Transformation).
- Patients who received treatment with any systemic chemotherapy, immunotherapy, targeted small molecule inhibitors, or other biologic agents within 30 days or 5 half-lives, whichever is shorter, of IOV-2001 infusion with the exception of ibrutinib or acalabrutinib

- Patients who have active systemic infections requiring systemic ABX, autoimmune anemia or thrombocytopenia, coagulation disorders, or other active major medical illnesses of the cardiovascular, respiratory, or immune system.
-
Patients who are seropositive for any of the following:
- Human immunodeficiency virus (HIV)-1 or HIV-2 antibodies
- Hepatitis B antigen (HbsAg) or anti-hepatitis B core total antibodies (anti-HbcAb), or hepatitis C antibody (HCVAb)
- Patients with active and chronic fungal, bacterial, or viral infection requiring IV treatment
