Phase 2
Completed
- Conditions
- Hypoparathyroidism
- Interventions

- Registration Number
- NCT02152228

Inclusion Criteria
- Confirmed diagnosis of primary hypoparathyroidism for more than 1 year.
- Currently taking >1.0 grams of Calcium/day with a correlate alpha D3 dose.
- 25(OH)D levels ≥ 20 ng/ml.
- Signed informed consent.
- BMI 18 - 30 kg/m2, inclusive.
- Full blood count should be within the reference range as per WHO criteria. Minor abnormalities will be assessed by the Principle Investigator and after discussion with sponsor patients may still be entered if these are felt to be of "no clinical importance". Abnormalities due to hypoparathyroidism related are acceptable and will not constitute exclusion.
- Patients with significant liver function impairment (liver enzymes above x3 the upper limit of normal range as per WHO criteria) will be excluded.
- Subjects able to adhere to the visit schedule and protocol requirements.
Exclusion Criteria
- Haemoglobin <12 g/dL (females)/ <13gm/dL (males) [lower limit of reference range 12-15 & 13-17]
- Impaired renal function
- impaired liver function; ALT >38 international units per liter (IU/L), or ALP>125 IU/L
- Significant drug or alcohol abuse as assessed by the Principal Investigator
- Allergy to soy bean products
- Presence of kidney or urinary tract stones
- Concurrent therapy that, in the Investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study medication.
- Treatment with any investigational product within the last 30 days, enrollment or intention to enroll in any active study involving the use of investigational devices or drugs.
- Presence of any other condition or circumstance that, in the judgment of the Investigator, might increase the risk to the patient or decrease the chance of obtaining satisfactory data to achieve the objectives of the study.
- Active infections
- Pregnancy or suspected pregnancy. Female subjects must have a negative serum pregnancy test at screening and be willing and able to use a medically acceptable method of birth control (reliable use of oral contraceptive, non-hormonal intrauterine device with condom, or diaphragm with condom, or condom with spermicide) from the screening visit through the study termination visit or declare that they are abstaining from sexual intercourse from the screening visit through the study termination visit or are surgically sterile (have undergone bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) or post-menopausal. Postmenopausal women are defined as women with menstruation cessation for 12 consecutive months prior to signing of the informed consent form.

- Primary Outcome Measures
Name Time Method Number of participants with adverse events up to 17 weeks safety will be measured by monitoring and recording adverse events related to hyper- and hypocalcemia
Reduction in use of exogenous calcium supplement and/or alpha D3 supplement up to 17 weeks Tolerability- The rate of discontinuation of patients' participation in the study due to adverse events up to 17 weeks Peak Plasma Concentration (Cmax)of treatment at baseline and time-points post-dose To study the pharmacokinetic profile of PTH absorption
Plasma calcium levels at baseline and 60 minutes post-dose
- Secondary Outcome Measures
Name Time Method Patient quality of life up to 17 weeks Patients will report a Quality Of Life (QOL) review
The volunteers' compliance to treatment up to 17 weeks Compliance to treatment defined as proportion taking \>80% study medication (good), 60-80% (satisfactory) and \<60% (poor)
