Brief Summary:
This is a randomized, double-blind, placebo-controlled study comparing the safety and efficacy of 2 dosage regimens of palovarotene versus placebo in preventing disease progression in pediatric subjects with multiple osteochondromas (MO).

Condition or disease Intervention/treatment Phase
Exostoses, Multiple Hereditary Drug: Palovarotene 2.5 mg Drug: Palovarotene 5.0 mg Other: Placebo Phase 2

Detailed Description:
Multiple osteochondromas is a rare condition where children develop multiple benign cartilage-capped bony tumors called osteochondromas on bones throughout the body, resulting in pain, deformity, limb length discrepancy, disability, and eventually arthritis and possible malignancy. The primary objective is to compare the efficacy of two dosage regimens of palovarotene with placebo to prevent the formation of new osteochondromas in pediatric MO subjects with exostosin 1 or exostosin 2 gene mutations. Osteochondroma formation will be assessed by whole body magnetic resonance imaging (MRI). Secondary efficacy objectives are to compare the effect of palovarotene on the volume of osteochondromas as assessed by MRI; and on the annualized rate of new or worsening deformities and MO-related surgeries. The overall safety of palovarotene and the effects of palovarotene on linear growth, bone growth plates, bone mineral density, quality of life, and pain due to osteochondromas will also be studied.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 240 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Multicenter, randomized, double-blind, placebo-controlled
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Efficacy and Safety Study of Palovarotene in Subjects With Multiple Osteochondromas
Actual Study Start Date : April 20, 2018
Estimated Primary Completion Date : January 2021
Estimated Study Completion Date : February 2021

Arm Intervention/treatment
Experimental: Palovarotene 2.5 mg daily regimen Drug: Palovarotene 2.5 mg
Subjects will receive a weight-adjusted dose equivalent of 2.5 mg palovarotene, once daily, for up to 24 months.

Experimental: Palovarotene 5.0 mg daily regimen Drug: Palovarotene 5.0 mg
Subjects will receive a weight-adjusted dose equivalent of 5.0 mg palovarotene, once daily, for up to 24 months.

Placebo Comparator: Placebo regimen Other: Placebo
Subjects will receive placebo, once daily, for up to 24 months.

Primary Outcome Measures :
  1. Annualized rate of new osteochondromas [ Time Frame: Month 24 ]
    The annualized rate of new osteochondromas as assessed by whole body magnetic resonance imaging (MRI).

Secondary Outcome Measures :
  1. Total volume of osteochondromas [ Time Frame: Months 12 and 24/end-of-treatment (EOT) ]
    The change from baseline in the total volume of osteochondromas as assessed by whole body MRI.

  2. Annualized rate of new or worsening deformities [ Time Frame: Months 12 and 24/EOT ]
    The annualized rate of new or worsening deformities as assessed by radiographic imaging of both upper and lower limbs.

  3. Annualized rate of MO-related surgeries [ Time Frame: Months 12 and 24/EOT ]
    The annualized rate of MO-related surgeries. Surgeries include surgical excisions of a symptomatic osteochondroma and surgical procedures to correct a joint deformities or functional limitations.

  4. Palovarotene area under the concentration-time curve (AUC) [ Time Frame: Month 1 ]
    Determination of AUC at steady-state assessed during treatment.

  5. Palatability [ Time Frame: Day 1 and Month 1 ]
    The palatability of the drug product versus placebo when sprinkled onto specific foods as assessed by a five-point hedonic face scale.

Other Outcome Measures:
  1. Safety of Palovarotene: Monitoring of adverse events [ Time Frame: Study Day 1; and from Months 1 to 30/ET at every subject contact ]
    Monitoring of adverse events.

  2. Volume of osteochondroma cartilage cap [ Time Frame: Months 12 and 24 ]
    Change from baseline in the total volume of cartilage cap of osteochondromas as assessed by whole body MRI

  3. Annualized rate of new or worsening functional limitations [ Time Frame: Months 12 and 24/EOT ]
    The annualized rate of new or worsening functional limitations. Functional limitations are defined as restrictions in joint range of motion.

  4. PedsQL [ Time Frame: Months 6, 12, 18, and 24/EOT ]
    The Pediatric Quality of Life Inventory (PedsQL, version 4.0) questionnaire to assess quality of life.

  5. PROMIS Global Health Scale [ Time Frame: Months 6, 12, 18, and 24/EOT ]
    The Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference pediatric item bank to assess the effect of pain on daily activities.

  6. FPS-R [ Time Frame: Months 6, 12, 18, and 24/EOT ]
    The Faces Pain Scale - Revised (FPS-R) to assess pain intensity.
