Brief Summary:
This is a randomized, double-blind, placebo-controlled, single ascending (SAD), and multiple ascending dose (MAD) study conducted at a single clinical site within the UK. Healthy male and female subjects (on non-child bearing potential) will be enrolled to investigate single inhaled doses of molgramostim at 3 dose levels (Part 1) and multiple inhaled doses at 2 dose levels (Part 2). The 2 doses in the multiple ascending dose regimens will be administered once daily (QD) for 6 consecutive days. The clinical indication for inhaled molgramostim is the treatment of respiratory diseases such as aPAP, bronchiectasis and cystic fibrosis. The Clinical trial will involve 42 healthy participants. The trial is expected to last approximately 4 months.

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Healthy, adult, male or female, 18- 55 years of age, inclusive, at screening.
  2. Life-long non smoker who has not used nicotine containing products.
  3. Body mass index (BMI) ≥ 18.5 and ≤ 32.0 kg/m2 at screening.
  4. Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, spirometry, vital signs, or ECGs, as deemed by the PI.
  5. Females must be of non-child bearing potential who must have undergone one of the following sterilization procedures at least 6 months prior to dosing in Part 1 or prior to the first dose in Part 2:

    • hysteroscopic sterilization;
    • bilateral tubal ligation or bilateral salpingectomy;
    • hysterectomy;
    • bilateral oophorectomy; or be postmenopausal with amenorrhea for at least 1 year prior to dosing in Part 1 or prior to the first dose in Part 2, and FSH serum levels consistent with postmenopausal status as per PI's judgment.
  6. A non vasectomized, male subject must agree to use a condom with spermicide or abstain from sexual intercourse during the study until 90 days beyond the last dose of study medication. (No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to study start. A male who has been vasectomized less than 4 months prior to study start must follow the same restrictions as a non vasectomized male).
  7. If male must agree not to donate sperm from dosing in Part 1 or from the first dose in Part 2, until 90 days following last dose.
  8. Understands the study procedures in the informed consent form (ICF), and be willing and able to comply with the protocol.

Exclusion Criteria:

  1. Subject is mentally or legally incapacitated or has significant emotional problems at the time of screening visit or expected during the conduct of the study.
  2. History or presence of clinically significant medical condition(s) (including ongoing active infections) or psychiatric condition(s) or disease(s) in the opinion of the PI.
  3. History of any illness that, in the opinion of the PI, might confound the results of the study or poses an additional risk to the subject by their participation in the study.
  4. Abnormal spirometry test results, in the opinion of the PI.
  5. History of severe or unexplained adverse reactions during aerosol delivery of any medicinal product.
  6. History or presence of alcoholism or drug abuse within the past 2 years prior to screening.
  7. History or presence of hypersensitivity or idiosyncratic reaction to molgramostim or to related compounds (i.e., Growgen®, Leucomax®, Leukine®, Topleucon™).
