Brief Title
Phase IIA Open Label Study to Evaluate Efficacy and Safety of BL-8040 Followed by (hATG), Cyclosporine and Methyprednisolone in Adult Subjects With Aplastic Anemia or Hypoplastic Myelodysplastic Syndrome
Official Title
A Phase IIA, Open-label Study Designed to Evaluate Efficacy and Safety of BL-8040 Followed by Anti-Thymocyte Globulin (hATG), Cyclosporine and Methylprednisolone in Adult Subjects With Aplastic Anemia (AA) or Hypoplastic Myelodysplastic Syndrome (MDS)
Brief Summary
An open label single arm study to assess efficacy and safety of BL-8040 on top of standard
immunotherapy regimen of hATG, cyclosporine and steroids in patients with Hypoplastic MDS and
AA over the course of a six month (180 day) treatment period.
Detailed Description
This will be an open-label, single arm, phase IIa study in subjects with AA or Hypoplastic
MDS.
Eligible subjects will receive subcutaneous (SC) injections of BL-8040 monotherapy over 10
days. From Day 11 through Day 14, subjects will receive hATG, Methylprednisolone and
Cyclosporine. From Day 15 until Day 30 (of the first month), subjects will continue treatment
only with Methylprednisolone and Cyclosporine. Cyclosporine will continue daily through Month
6/Day 30 (M6/D30) (end of study treatment). Beginning on M2/D1, BL-8040 will be administered
daily as part of the maintenance period for the first 5 days of each month through M6. All
BL-8040 injection courses will be given at the site, as either an inpatient or outpatient per
the treating physician's decision.
The primary objective of the study is to determine the efficacy of the treatment with BL-8040
on top of the standard immunotherapy regimen of: hATG, cyclosporine, and steroids in patients
with Hypoplastic MDS and AA. Safety and efficacy will be assessed at defined time-points
throughout the study. Duration of response and overall survival will be assessed as a part of
the long term FU. A maximum of 25 patients will be enrolled in the study. Subjects will be
equally distributed between the disease populations.

Description: BL-8040 0.75mg/kg will be administered Subcutaneously (SC ) on Days 1-10, then on first 5 days of months 2-6. Standard therapy: hATG: Days 11-14: 40mg/kg/day IV over 6-8 hours, in all AA subjects, or in MDS subjects less than 55 years old. 35mg/kg/day IV over 6-8 hours in MDS subjects 55 years and older. Standard therapy: methylprednisolone: Days 11-14: 40mg/kg/day IV over 6-8 hours, in all AA subjects, or in MDS subjects less than 55 years old. 35mg/kg/day IV over 6-8 hours in MDS subjects 55 years and older. Standard therapy: cyclosporine: 5mg/kg/day orally, given in 2 divided doses, starting on day 11 and continuing through Month 6 Day 30 (end of treatment)

Eligibility Criteria
Inclusion Criteria:
1. Adult men and women aged 18 and older
2. Patient must have the ability to understand the requirements of the study and provide
informed consent.
3. Patients with the diagnosis of severe AA, who are not currently candidates for an
allogeneic stem cell transplant, fulfilling the following criteria:
1. BM cellularity < 30% and
2. Peripheral blood (PB) showing at least two of the following criteria:
Absolute neutrophil count (ANC) < 0.5 k/µL Platelet count < 30 k/µL Absolute
reticulocyte count < 60,000/µL
4. Patients with recurrent/relapsed AA will be eligible for the trial as long as they
were not previously refractory to hATG-based therapy and the relapse occurred > 3
months after response.
5. Patients with Hypoplastic MDS defined as MDS with marrow cellularity of:
- < 30% for patients < 60 years,
- < 20% for patients ≥ 60yrs.
6. Patients must have been off of cytotoxic, immunosuppressive (except steroids), or
targeted therapy, including standard and investigational treatments for AA, for at
least 1 week or 5 half-lives whichever comes later, prior to entering this study, and
have recovered from the toxic effects of that therapy to Grade 1 or less.
7. Adequate organ function as defined below:
• Liver function:
a. Total bilirubin < 2.0 mg/dL (34 µmol/L) b. AST and/or ALT <3 x ULN
- Kidney function: creatinine < 2.5 x ULN.
8. ECOG performance status of ≤ 2.
9. Women of childbearing potential and all men must agree to use an approved form of
contraception (e.g. oral, transdermal patch, implanted contraceptives, intrauterine
device, diaphragm, condom, abstinence or surgical sterility) prior to study entry and
for the duration of study participation through 30 days after the last dose of the
last treatment drug. Pregnancy testing is not required for post-menopausal or
surgically sterilized women.
10. Subject is able and willing to comply with the requirements of the protocol.
11. Subject or a legal guardian is able to voluntarily provide written informed consent.
Exclusion Criteria:
- 1. Known allergy or hypersensitivity to any of the test compounds, materials or
contraindication to test product.
2. Patients who have had any major surgical procedure within 14 days of Day 1. BM
biopsy is not considered a major surgical procedure.
3. Pregnant women are excluded from this study because the agents used in this study
have the potential for teratogenic or abortifacient effects. Because there is an
unknown but potential risk for adverse events in nursing infants secondary to
treatment of the mother with these agents, breastfeeding should be discontinued if the
mother is being treated on this trial.
4. Seropositive for HIV antibodies (HIV1 and HIV2), Hepatitis C antibody (Hep C Ab) or
a Hepatitis B carrier (positive for Hepatitis B surface antigen [HBsAg]).
5. Life expectancy of ≤ 2 months. 6. Subjects with a clinically significant or
unstable medical or surgical condition or any other condition that cannot be
well-controlled by the allowed medications permitted in the study protocol that would
preclude safe and complete study participation, as determined by medical history,
physical examinations, ECG, laboratory tests or chest X-ray. Such conditions may
include:
• Unstable cardiovascular conditions at Baseline including but not limited to:
- Symptomatic ischemia, or
- Uncontrolled clinically significant conduction abnormalities (e.g., ventricular
tachycardia on antiarrhythmic agents are excluded; 1st degree atrioventricular
(AV) block or asymptomatic left anterior fascicular block/right bundle branch
block (LAFB/RBBB) will not be excluded); or
- Congestive heart failure (CHF) NYHA Class ≥ 3, or
- Myocardial infarction (MI) within 3 months. • Presence of active, uncontrolled
infection. • Known central nervous system illness (e.g., Alzheimer's disease).
- A gastrointestinal disorder that may affect the absorption of study
medication.
- Use of alcohol or drug use that may interfere with the patient's ability to
participate in the study.
- Unstable psychiatric disorder that would render the patient unable to comply
with study requirements.
- Any malignancies in the 3 years prior to Baseline, excluding basal cell
carcinoma, in situ malignancy, low-risk prostate cancer, cervical cancer
after curative therapy.
- A co-morbid condition that, in the Investigator's opinion, renders the
subject at high risk for treatment complications.
7. Unable to comply with study requirements in the opinion of the
Investigator.
