Subjects are randomized to have the second bone biopsy done 1,2, or 4 years after the start of PTH.

Cohort 1 was treated with HPTH therapy on original protocol. Cohort 1 participants who consented to the new protocol and were treated with HPTH on the new protocol were followed for safety outcomes only. The Safety population of Cohort 1 consisted of 7 participants.

Cohort 1 (HPTH on Old Study) and Received HPTH on New Study

Cohort 2 consists of participants previously treated with conventional care (CC) throughout the original protocol. Cohort 2 participants who received at least one dose of HPTH on the new protocol were included in safety population. Cohort 2 safety population includes 5 participants.

Cohort 2 (CC on Old Study) and Treated With HPTH on New Study

Cohort 3 consists of new participants (i.e. not previously enrolled) that consented to the revised protocol. The Cohort 3 safety population includes 19 subjects who received any HPTH on the new study.

Participants (in Cohorts 2 and 3) were randomized to receive their second bone biopsy at year 1, 2, or 4 after the start of HPTH therapy. For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced due to the early termination of the study, so the 2-, and 4-year biopsies were collapsed into one biopsy year group. Cn.BV/TV is one of 8 primary endpoints measured from the bone biopsy. The changes in Cn.BV/TV outcome between two time-points are being reported. The unit of measure is a z-score. Z-scores are normed to standard populations to a mean of zero and a standard deviation of 1. The normal range for a z-score is from -2 to 2. Values above or below this normal range are considered worse outcomes.

Cohort 2 consists of participants previously treated with conventional care (CC) throughout the original protocol. Cohort 3 consisted of all new participants. Efficacy outcomes were only analyzed for Cohorts 2 and 3. (Cohort 1 consisted of previously enrolled participants who were on HPTH therapy on the original protocol and continued on HPTH on the new study as a separate group. These participants were not randomized to a bone biopsy year, nor did they have additional biopsies performed. Cohort 1 participants were followed for safety outcomes only. )

Change in Bone Biopsy Cancellous Bone Volume (Cn.BV/TV)

Participants (in Cohorts 2 and 3) were randomized to receive their second bone biopsy at year 1, 2, or 4 after the start of HPTH therapy. For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced due to the early termination of the study, so the 2-, and 4-year biopsies were collapsed into one biopsy year group. Ct.Po.N is a bone biopsy measure that assess the amount of holes in the cortical bone within a predetermined area of cortical bone. The changes in Cn.BV/TV outcome between two time-points are being reported. Cortical bone with a higher number of holes may be at greater risk of fracture. The n's in the outcome measure table refer to the number of complete records (non-missing baseline and post-baseline measures).

Change in Total Number of Cortical Pores Per mm^2 (Ct.Po.N)

Participants (in Cohorts 2 and 3) were randomized to receive their second bone biopsy at year 1, 2, or 4 after the start of HPTH therapy. For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced due to the early termination of the study, the 2-, and 4-year biopsies were collapsed into one biopsy year group. Cn.BFR/BS, measured from the bone biopsy, is the cancellous bone formation rate per unit of bone surface where cancellous refers to the spongy structure of the bone. The changes in Cn.BFR/BS between two time-points are being reported. The unit of measure is a z-score. Z-scores are normed to standard populations to a mean of zero and a standard deviation of 1. The normal range for a z-score is from -2 to 2. Values above or below this normal range are considered worse outcomes.

Change in Cancellous Bone Formation Rate Per Unit of Bone Surface (Cn.BFR/BS)

Following their baseline bone biopsy, 5, 5, and 2 participants were randomized to receive their second bone biopsy at years 1, 2, and 4 after the start of HPTH therapy, respectively. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced in size due to withdrawal and the early termination of the study, the 2-, and 4-year biopsies were collapsed into one biopsy year group. Cn.MS/BS is measured from the bone biopsy. This measure demonstrates the percentage of the cancellous bone surface that is actively forming bone. The region of interest is the predefined area of total bone that is being measured. The changes in Cn.MS/BS between two time-points are being reported.

Cohort 1 consisted of previously enrolled participants who were on HPTH therapy, were re-consented, and allowed to continue on the current study as a separate group. These participants were not randomized to a bone biopsy year, nor did they have additional biopsies performed. Cohort 1 participants were followed for safety outcomes only. Cohort 2 were previously enrolled participants on conventional care, were re-consented, re-enrolled, and randomized to a biopsy year. Cohort 3 consisted of all new participants consent, enrolled and randomized to a biopsy year. Efficacy outcomes were only analyzed for Cohorts 2 and 3 combined.

Participants (in Cohorts 2 and 3) were randomized to receive their second bone biopsy at year 1, 2, or 4 after the start of HPTH therapy. For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose.

Perceived interference is measured using seven separate items that assess the degree to which fatigue in the past week was judged to interfere with general level of activity, ability to bathe and dress, normal work activity, ability to concentrate, relations with others, enjoyment of life, and mood. The interference ratings were summed to yield a total interference score ranging from 0 (no perceived interference due to fatigue) to 70 (maximum possible perceived interference due to fatigue).

Perceived Interference (PI) of the Fatigue Symptom Inventory (FSI)

Severity is measured using four separate items of the FSI questionnaire that assesses how the participant felt on their most, least, and average fatigue days in the past week as well as current fatigue. Participants score their level of fatigue for each item on an 11-point scale (0=not at all fatigued, 10=as fatigued as I could be). An average is taken of sum of these 4 scores. The average severity score can range from 0 to 10. A higher average severity score indicates that the participant is experiencing more severe fatigue.

Severity is measured using four separate items of the FSI questionnaire that assesses how the participant felt on their most, least, and average fatigue days in the past week as well as current fatigue. Participants score their level of fatigue for each item on an 11-point scale (0=not at all fatigued, 10=as fatigued as I could be). The composite severity score reflects the sum of these 4 scores. The composite severity scores can range from 0 to 40. A higher composite severity scores indicates that the participant is experiencing more severe fatigue.

The Bodily Pain (BP) domain scores are derived from the SF36 Health Survey taken by the participant. The SF-36 is a validated questionnaire assessing 4 physical domains: physical function, physical role limitations, bodily pain, and general health, and 4 mental domains: vitality, emotional role limitations, social function and mental health. From the 36 questions asked, a scoring tool derives SF36 domain scores for each of the eight domains. These domain scores are scaled to range from 0 to 100 with a population mean of 50 and a standard deviation of 10. Lower scores indicate more disability; and, higher scores indicate less disability. The BP domain scores indicate to what extent a participant's bodily pain hinders their performance of daily activities.
