Details and patient eligibility
About
This study is investigating the optimal dose and the advantage in combining investigational immunotherapy drugs known as Retifanlimab, INCAGN02385 and INCAGN02390 to improve the responses to CAR T-cell therapy. Additionally, the study will investigate that triple checkpoint blockade of PD-1, TIM-3 and LAG-3 molecules will overcome CAR T-cell therapy resistance in patients with suboptimal responses.

-
Adequate organ function as defined below unless attributed to disease involvement.
- liver function (bilirubin < 2mg/dL, AST and/or ALT <3 x ULN)

- TnT or TnI < 2 × Institutional ULN. Participants with TnT or TnI levels between > 1 to 2 × ULN will be permitted if repeat levels within 24 hours are ≤ 1 × ULN.
-
Patients with HIV can be included if they are on appropriate antiretroviral therapy, a CD4+ T-cell counts ≥ 300 cells/µL and no detectable viral load.
-
Age ≥ 18 years of age.
-
Eastern Cooperative Group performance (ECOG) status of 0 to 2.
-
A negative urine pregnancy test is required within 1 week for all women of childbearing potential prior to enrolling on this trial.
-
For females of reproductive potential: use of highly effective contraception for at least 1 month prior to screening and agreement to use such a method during study participation and for an additional 6 months after infusion of study drug.
-
For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner.
-
Willing and able to participate in all required evaluations and procedures in this study protocol including receiving intravenous administration of investigational product and being admitted, when required, for at least 24 hours during investigational product administration.
Exclusion criteria
-
Patients who experienced Grade 3 or higher Cytokine release syndrome (CRS) or Immune cell associated neurotoxicity syndrome (ICANS) with CAR T-cell therapy as per ASTCT criteria.
-
Patients with ongoing CRS or ICANS.
-
Patients who experienced hemophagocytic lymphohistiocytosis (HLH) due to CAR T- cell therapy.
-
Prior allogeneic stem cell transplant within 6 months. The patient should not have any active Graft vs. Host disease (GVH) or should be on immune suppressive agents.
-
Prior treatment with PD-(L)1, TIM-3 or LAG-3 blocking therapy.
-
Any active, concurrent, significant illness or disease (other underlying lymphoma) or clinically significant findings including psychiatric and behavioral problems, medical history and/or physical examination findings that would preclude the patient from participation in the study such as:
- active infection requiring systemic therapy ≤14 days before the first dose of study drug
- unstable angina pectoris, symptomatic congestive heart failure (New York Heart Association [NYHA] II, III, IV;), myocardial infarction ≤6 months prior to first study drug, uncontrolled cardiac arrhythmia e.g., atrial fibrillation/flutter, cerebrovascular accidents ≤6 months before first dose of study drug
- Significant (as defined by study doctor) pulmonary disease or disorder, including interstitial lung disease or history of interstitial lung disease, or active, noninfectious pneumonitis.
- Severe autoimmune disorder with evidence of significant organ damage from autoimmune disorder as defined by study physician.
- any severe or uncontrolled other disease or condition which might increase the risk associated with study participation.
- History of myocarditis as defined by a cardiologist requiring immunosuppressive therapies.
- Clinically significant third space fluid accumulation (i.e., ascites requiring drainage or pleural effusion that is either requiring drainage or associated with shortness of breath) and not related to underlying lymphoma.
-
Vaccination with live, attenuated vaccines within 28 days prior to the first dose of study medication.
-
Patients who develop COVID-19 (SARS-CoV2) infection at any time during screening, should not be enrolled until a negative PCR is confirmed and all clinical symptoms (as applicable) have resolved.
-
Receiving systemic immunosuppressive medications (including, but not limited to, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor agents). The use of inhaled corticosteroids is permitted.
-
Corticosteroids ≥ 10 mg of prednisone within 7 days of first dose of study drug.
Notes:
- Physiologic corticosteroid replacement therapy at doses > 10 mg/day of prednisone or equivalent for adrenal or pituitary insufficiency and in the absence of active autoimmune disease is permitted.
- Participants with a condition (eg, asthma or COPD) that requires intermittent use of bronchodilators, inhaled steroids, or local steroid injections may participate.
- Participants using topical, ocular, intra-articular, or intranasal steroids (with minimal systemic absorption) may participate.
- Brief courses of corticosteroids for prophylaxis (e.g., contrast dye allergy) or study treatment-related standard premedication are permitted.
-
Has known active HBV or HCV infection, or risk of reactivation of HBV or HCV, defined as follows (testing must be performed to determine eligibility):
- Active HBV infection is defined by positive HBsAg and positive total anti-HBc results.
Note: When HBsAg is negative AND HBcAb and/or HBsAb is positive, HBV-DNA should be measured. When HBV-DNA is negative, this participant could be enrolled with close monitoring of HBV activities.
- Active HCV is defined as a positive HCV antibody result and quantitative HCV-RNA results greater than the lower limits of detection of the assay.
Note: Participants positive for HCV antibody will be eligible if they are negative for HCV-RNA. Participants who have had definitive treatment for HCV are permitted if HCV RNA is undetectable.
-
Patients with prior solid organ transplant
-
Breastfeeding or pregnant
-
Any other malignancy known to be active, with the exception of
- Cervical carcinoma of Stage 1B or less
- Non-invasive basal cell or squamous cell skin carcinoma
- Non-invasive, superficial bladder cancer
- Prostate cancer with a current PSA level < 0.1 ng/mL
- Any curable or localized cancer with a CR of > 2 years' duration.
-
Known allergy or hypersensitivity to any component of either retifanlimab, INCAGN02385, or INCAGN02390 study drug formulation (including excipients and additives). Patients with known hypersensitivity to another monoclonal antibody that cannot be controlled with standard measures such as antihistamines and/or corticosteroids will also be excluded.
