CD4-Directed Chimeric Antigen Receptor T-cells for the Treatment of Patients with Relapsed or Refractory CD4+ Hematologic Cancers
This phase I trial tests the safety, side effects, and best dose of CD4-directed chimeric antigen receptor engineered T cells (CD4CAR) in treating patients with CD4+ leukemia or lymphoma that has come back (relapsed) or that does not respond completely to treatment (refractory). CD4CAR is a type of chimeric antigen receptor (CAR) T cell therapy. CAR T cell therapy uses the body's own immune cells, called T cells, to try and kill cancerous cells. T cells fight infections and can also kill cancer cells in some cases. T cells will be removed from blood, changed in a laboratory, and then given back by intravenous infusion. While in the laboratory, new genetic material will be put into the T cells using a virus. T cells that have genetic material added are called genetically changed T cells. If the genetically changed T cells recognize and attach to cancer cells, they may have the ability to kill them.

- Adequate venous access for apheresis and no other contraindications for leukapheresis
- CONDITIONING CHEMOTHERAPY: Specific organ function criteria for cardiac, renal, and liver function must be similar to initial inclusion values
- CONDITIONING CHEMOTHERAPY: Review of co-morbidities to confirm no major changes in health status (examples of major changes include heart attack, stroke, and any major trauma)
- CONDITIONING CHEMOTHERAPY: Planned infusion dose was successfully manufactured and met release criteria
- CD4CAR INFUSION: Afebrile and not receiving antipyretics, and no evidence of active infection
- CD4CAR INFUSION: Specific organ function criteria for cardiac, renal, and liver function must be similar to initial inclusion values. The following tests do not need repeated: an echocardiogram if within 6 weeks of initial assessment, and the PFT if completed within 6 months from day 0
- CD4CAR INFUSION: Negative pregnancy testing (if applicable)
- CD4CAR INFUSION: If previous history of corticosteroid chemotherapy, subject must be off all but adrenal replacement doses 3 days before the CD4CAR infusion
Exclusion Criteria
- Pregnant or lactating women. The safety of this therapy on unborn children is not known. Female study participants of reproductive potential must have a negative serum or urine pregnancy test prior to initiation of conditioning chemotherapy, per research sites’ clinical policy
- Uncontrolled active infection necessitating systemic therapy
- Active hepatitis B or hepatitis C infection. Active hepatitis C is defined as the hepatitis C antibody is positive while quantitative hepatitis C virus (HCV) ribonucleic acid (RNA) results exceed the lower detection limit. Note the following subjects will be eligible: * Subjects with a history of hepatitis B but have received antiviral therapy and have non-detectable viral DNA for 6 months prior to enrollment are eligible * Subjects seropositive for HBS antibodies due to hepatitis B virus vaccine with no signs or active infection (Negative HBs Ag, HBc and HBe Ags) are eligible * Subjects who had hepatitis C but have received antiviral therapy and show no detectable hepatitis C virus (HCV) viral RNA for 6 months are eligible * If hepatitis C antibody test is positive, then patients must be tested for the presence of antigen by reverse transcription-polymerase chain reaction (RT-PCR) and be hepatitis C virus ribonucleic acid (HCV RNA) negative
- Concurrent use of systemic glucocorticoids in greater than replacement doses (unless as a part of a standard of care salvage therapy or conditioning protocol), or steroid dependency defined in rheumatological and pulmonary diseases as uninterrupted corticosteroid intake for more than a year at a dosage of 0.3 mg/kg/day or greater, and where the underlying disease worsens on temporary stoppage of steroid therapy, with symptoms of steroids withdrawal (eg, lethargy, headache, weakness, pseudorheumatism, emotional disturbances, etc) precipitated by the temporary stoppage. Subjects who receive daily corticosteroids in replacement doses can be included in the study. The replacement doses are defined as following: * Hydrocortisone 25mg/day or less * Prednisone 10mg/day or less * Dexamethasone 4mg or less Note: Recent or current use of inhaled glucocorticoids is not exclusionary, as this route pertains extremely minimal systemic penetration
- Any previous treatment with any gene therapy products
- Any uncontrolled active medical disorder that would preclude participation as outlined in the opinion of the treating investigator and/or study chair
- Human immunodeficiency virus (HIV) infection
- Patients declining to consent for treatment
- Subjects who have received or will receive live vaccines within 30 days before the first experimental cell treatment. Inactivated seasonal flu vaccination is allowed
- Subjects with active autoimmune diseases who need systematic treatments (such as disease modifying agents, corticosteroids and immunosuppressive drugs) in the last 2 years. Note: Replacement therapy (thyroxine, insulin or physiological corticosteroid replacement therapy (up to10 mg of oral daily prednisone or equivalent in hydrocortisone and dexamethasone) to treat adrenal dysfunction or pituitary dysfunction) is not considered as systematic therapy. Subjects who need inhalation corticosteroid therapy can be included in this trial. Subjects with vitiligo or in long-term remission of pediatric asthma or allergic diseases can be included in this trial
- Subjects with a history of mental disorders or drug abuse that may influence treatment compliance
- Active malignancy not related to a T-cell malignancy that has required therapy in the last 3 years or is not in complete remission. Exceptions to this criterion include successfully treated non-metastatic basal cell or squamous cell skin carcinoma, or prostate cancer that does not require therapy. Other similar malignant conditions may be discussed with and permitted by the Principal Investigator
- Participation in another clinical study with an investigational product within the past 18 months

PRIMARY OBJECTIVES:
I. To identify dose-limiting toxicities of anti-CD4 CAR T-cells (CD4CAR) and the recommended phase II dose.
II. Describe toxicity profile of CD4CAR within the scheduled dose escalation.
SECONDARY OBJECTIVES:
I. To determine the duration of in vivo persistence of the CD4CAR, including:
Ia. Evaluate trafficking of CD4CAR cells to tumor sites in bone marrow and lymph nodes and relation to efficacy;
Ib. Determine if cellular or humoral host immunity develops against the murine anti-CD4, and assess correlation with loss of detectable CD4CAR (loss of engraftment);
Ic. Evaluate the relative subsets of CD4CAR T cells (central memory T-lymphocyte [Tcm], effector memory T-lymphocyte [Tem], and type 1 regulatory T-cell [Tregs]).
II. Describe CD4CAR associated cytokine production.
III. Determine the effect of undergoing hematopoietic cell transplantation (HSCT) within three months of receiving CD4CAR in patients who become eligible to undergo the procedure.
IV. Tissue banking for future research.
V. Document any preliminary evidence of objective antitumor activity.
VI. Evaluate biomarkers and cytokines in relation to toxicity and efficacy including cerebrospinal fluid (CSF) levels.
VII. Examine for T cell function upon T cell recovery.
OUTLINE: This is a dose escalation study.
Patients undergo leukapheresis on days -42 to -35, receive fludarabine and cyclophosphamide intravenously (IV) on days -4 to -2, and receive CD4CAR IV over 20-30 minutes on day 0 on trial. Patients may undergo blood sample collections throughout the trial, echocardiography (ECHO) during screening and as clinically indicated, as well as bone marrow aspiration and biopsy and tissue sample collection as clinically indicated.
After completion of study treatment, patients are followed up quarterly for 2 years and then up to twice a year for 13 years.
