About this study

A total of 207 subjects will be randomized into the study which will employ a double-blind placebo-controlled setting to assess the efficacy and safety of G-CSF + BL-8040 as compared to G-CSF + placebo.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

      • Total Bilirubin ≤ 2.0 x ULN unless the subject has Gilbert disease.
    • Coagulation test:
      • INR or PT: ≤ 1.5 x ULN unless subject is receiving anticoagulant therapy, as long as PT or PTT is within therapeutic range of intended use of anticoagulants;
      • aPTT: ≤ 1.5 x ULN unless subject is receiving anticoagulant therapy, as long as PT or PTT is within therapeutic range of intended use of anticoagulants.
  • Female subjects must be of non-childbearing potential or, if of childbearing potential, must have a negative serum pregnancy test at screening and negative urine/serum pregnancy test within 72 hours prior to G-CSF first administration.
  • Women of childbearing potential must agree to use 2 methods of effective contraception: One barrier method (e.g., diaphragm, or condom or sponge, each of which are to be combined with a spermicide) and one hormonal method, unless she uses a highly effective method. Highly effective methods of contraception include:
    • Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, transdermal;
    • Progestogen-only hormonal contraception associated with inhibition of ovulation: oral, injectable, implantable;
    • Intrauterine device (IUD);
    • Intrauterine hormone-releasing system (IUS);
    • Bilateral tubal occlusion;
    • Vasectomised partner;
    • Sexual abstinence.
    • These methods must be used prior to study entry and for the duration of study participation through 30 days after the last dose of study treatment. Non-childbearing potential is defined as (by other than medical reasons):
      • ≥ 45 years of age and has not had menses for over 2 years;
      • Amenorrheic for > 2 years without a hysterectomy and oophorectomy and a Follicle Stimulating Hormone (FSH) value in the postmenopausal range upon pretrial (screening) evaluation.
      • Post hysterectomy, bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation at least 6 weeks prior to screening. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure; otherwise the subject must be willing to use two adequate barrier methods throughout the study, starting with the Screening Visit, through 30 days after the last dose of study drug. Information must be captured appropriately within the site's source documents.
  • Male subjects must agree to use an adequate method of contraception starting with the first day of G-CSF treatment through 30 days after the last dose of study drug.
