Study Arms (2)

Placebo

PLACEBO COMPARATOR

In this study, 60 subjects will be randomized to receive either PRO 140 or placebo in a 1:1 ratio (i.e. 30 subjects per arm). PRO 140 or placebo will be administered as a 350 mg subcutaneous injection. Placebo will be administered -2/-3 days before the stem cell infusion, on the day of stem cell infusion (Day 0) and thereafter on days 7, 14, 21, 28, 42, 56, 70, 84 and 98 as per the study schedule of assessments. Each vial of the Placebo contains 5mM Histidine, 15 mM Glycine, 95 mM Sodium Chloride, 0.3% (w/v) Sorbitol, 0.005% (w/v) Polysorbate 20 at a pH of 5.5. Each 350 mg dose of placebo consist of 2 SC injections of placebo (5mM Histidine, 15 mM Glycine, 95 mM Sodium Chloride, 0.3% (w/v) Sorbitol, 0.005% (w/v) Polysorbate 20 at a pH of 5.5) of 2 X 1 mL/inj. on opposite sides of abdomen.

Drug: Placebo

350 mg Pro140

EXPERIMENTAL

In this study, 60 subjects will be randomized to receive either PRO 140 or placebo in a 1:1 ratio (i.e.,30 subjects per arm). PRO 140 or placebo will be administered as a 350 mg subcutaneous injection. PRO 140 will be administered -2/-3 days before the stem cell infusion, on the day of stem cell infusion (Day 0) and thereafter on days 7, 14, 21, 28, 42, 56, 70, 84 and 98 as per the study schedule of assessments. Each vial of the PRO 140 product contains 1.4 mL antibody at 175 mg/ml in a buffer containing 5 mM L-histidine, 15.0 mM glycine, 95 mM sodium chloride, 0.3% (w/v) sorbitol, 0.005% (w/v) polysorbate 20 (Tween 20®), and sterile water for injection, at pH of 5.5. Each 350 mg dose of PRO 140 will consist of 2 SC injections of PRO 140 (2 X 1 mL/inj.) on opposite sides of abdomen.

Drug: PRO 140

Interventions

PRO 140 is a humanized IgG4,κ monoclonal antibody (mAb) to the chemokine receptor CCR5.

Also known as: Humanized monoclonal antibody to CCR5
350 mg Pro140

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects must meet all of the following criteria to be included in the study:
  • Patients diagnosed with AML or MDS per below:
  • Patients with a history of histologically or pathologically confirmed diagnosis of AML and \< 5% blasts in the peripheral blood or bone marrow (per bone marrow aspiration and/or biopsy within 6 weeks prior to screening) scheduled to undergo allogeneic stem-cell transplantation
  • Patients with a histologically or pathologically confirmed diagnosis of MDS with \< 10% blasts in the bone marrow (per bone marrow aspiration and/or biopsy within 6 weeks prior to screening) scheduled to undergo allogeneic stem-cell transplantation
  • Eastern Cooperative Oncology Group (ECOG) performance status score ≤ 2
  • Patients must have normal organ function as defined below:
  • Myeloablative allogeneic HCT:
  • Males and females, age ≥18 and ≤ 65 years of age
  • Total bilirubin ≤ 2 mg/dL (except in patients with Gilbert's Syndrome)
  • AST/ALT ≤ 3 times institutional upper limit of normal (except in patients with leukemic infiltration of liver)
  • Serum creatinine ≤ 2 mg/dL and creatinine clearance ≥ 60 ml/hr
  • Diffusing capacity of the lung for carbon monoxide (DLCO) \> 50% predicted with no symptomatic pulmonary disease
  • Cardiac ejection fraction ≥ 50%. If between 40-49% a cardiology consult is required
  • Clinically normal resting 12-lead ECG at screening visit or, if abnormal, considered not clinically significant by the PI
  • Patients must have a reasonable expectation of ≥ 6 months survival
  • +6 more criteria

You may not qualify if:

  • Subjects meeting any of the following criteria will be excluded from the study:
  • Patients not expected to be available for follow-up for at least 114 days after transplant
  • Patients who have received prior allogeneic stem cell-transplantation
  • Patients who receive post-transplant high dose cyclophosphamide
  • Patients with active central nervous system (CNS) involvement by malignant cells
  • Patients receiving other investigational drugs for GVHD. Co-enrollment in other clinical trials that do not include experimental GVHD therapies is allowed.
  • Prior use of any experimental or approved CCR5 modulator including maraviroc and PRO 140
  • Patients with uncontrolled bacterial, viral or fungal infections including diagnosis of acute viral hepatitis (defined as any active infection with hepatitis A or a new diagnosis of hepatitis B or C within 24 weeks of dosing)
  • Currently active second malignancy other than non-melanoma skin cancers
  • Presence of fluid collection (ascites, pleural or pericardial effusion) that interferes with methotrexate clearance or makes methotrexate use contraindicated
  • Patients who are HIV positive
  • Females who are pregnant, lactating, or breastfeeding, or who plan to become pregnant during the study
  • Subjects on chronic steroid therapy \> 5 mg/day within 2 weeks of screening except for inhaled, nasal, or topical steroids
  • Any other clinical condition that, in the Investigator's judgment, would potentially compromise study compliance or the ability to evaluate safety/efficacy
