  Purpose
ALTU-238 is a long acting crystalline formulation of recombinant human growth hormone (rhGH) that is being developed for the treatment of growth hormone deficiency in adults and children. ALTU-238 is designed to require fewer injections than the currently available formulations of rhGH.

Condition Intervention Phase
Adult Growth Hormone Deficiency Drug: ALTU-238 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II, Multi-Center, Multi-Dose, Randomized, Open-Label, Parallel Group Study of an Extended-Release, Crystalline Formulation of Recombinant Human Growth Hormone (ALTU-238) in Growth Hormone Deficient Adults to Determine Pharmacokinetics, Pharmacodynamics, and Drug Safety

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Growth hormone deficient men and women ages 18-60 years with a hypothalamic and/or pituitary structural lesion or longstanding idiopathic GHD
  • Growth hormone deficiency as determined by pituitary testing within the last five years by either of the two following tests:

    1. Insulin hypoglycemia (glucose < 50 mg/dL) with maximum GH < 5 ng/mL (5 µg/L) by radioimmunoassay or < 2.5 µg/L, if measured by immunoradiometric assay
    2. Arginine-GHRH infusions with maximum GH < 5 ng/mL (5 µg/L) or < 2.5 µg/L, if measured by immunoradiometric assay
  • Women must be of non-child bearing potential (hysterectomy, tubal ligation, or IUD are acceptable) during the three months prior to entering the study, or post-menopausal (no menses for one year or more), or six to twelve months without menses and β-estradiol levels < 20 pg/mL
  • Glucocorticoid use is allowed provided the subject has been on physiologic (<7.5 mg prednisone or equivalent/day) replacement doses for at least 3 months
  • Free thyroxine (T4) within the normal range at Screening. If the subject is receiving thyroid hormone replacement therapy, the dose must be stable for at least 6 weeks prior to Screening
  • Willing and able to provide written informed consent
  • BMI 20 - 36 kg/m2

Exclusion Criteria:

  • Any previous or ongoing clinically significant illness that, in the opinion of the investigator, could prevent the subject from completing the study
  • Any history of cancer within the past 5 years, except for dermal squamous and basal cell carcinoma with documented 6-month remission. Subjects with a more recent history of successfully treated cervical carcinoma in situ will not be excluded provided there is documented 12-month remission
  • BMI <20 or >36 kg/m2
  • Any allergic or abnormal reaction to human growth hormone
  • Inability of the subject to discontinue use of their regularly prescribed human growth hormone treatment from six weeks prior to Day -1 through the completion of the study
  • Serum creatinine > 1.4 mg/dL
  • Hypocalcemia or hypercalcemia from any cause
  • Hyperparathyroidism, osteomalacia or any other disorder which may affect bone and bone markers including the use of bisphosphonates or other medications for osteoporosis
  • Participation in another clinical trial 30 days prior to screening
  • Demonstrated inability to comply with protocol requirements (e.g. uncooperative attitude, inability to return for follow-up visits, history of medical non-compliance, and/or poor likelihood of completing the study)
  • Blood donation within 56 days of the screening visit
  • Plasma donation within seven days of the screening visit
  • Positive serum pregnancy test
  • Women of child bearing potential
  • Abuse of alcohol; to be determined by principal investigator
  • Abuse of prescription or illicit drugs; to be determined by principal investigator
