Study of Zoledronic Acid, Pravastatin, and Lonafarnib for Patients With Progeria
Hutchinson-Gilford Progeria Syndrome (Progeria) is a rare autosomal disease that results in premature death at a median age of 13 years due to cardiovascular and cerebralvascular compromise. The mutation for this disease has been identified and results in a mutant form of lamin A that cannot be de-farnesylated. This study evaluates the combination of pravastain (a statin), lonafarnib (a farnesyltransferase inhibitor) and zoledronic acid (a bisphosphonate) in an open label phase II efficacy trial in children with Progeria. These agents all target farnesylation pathways at different points. Patients with genetically confirmed progeria will be eligible for this protocol. Treatment will be initiated for 24 months duration. Clinical and biologic parameters will be examined to assess response.

|Official Title:||An Open Label Phase II Trial of Zoledronic Acid, Pravastatin, and Lonafarnib for Patients With Hutchinson-Gilford Progeria Syndrome(HGPS) and Progeroid Laminopathies|
- To evaluate the therapeutic effects of the combination of zoledronic acid, pravastatin and lonafarnib in patients with HGPS. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To describe any acute and chronic toxicities associated with treating progeria patients with the combination of zoledronic acid, pravastatin and lonafarnib. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- To investigate which clinical and laboratory studies are needed to monitor or alter therapy to prevent unacceptable toxicity. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
- To assess the pharmacokinetics of lonafarnib in patients with progeria. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To assay for the inhibition of HDJ-2 farnesylation in Peripheral Blood Leukocytes (PBL). [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To assay for changes in research-based potential markers of efficacy such as levels of prelamin A, mature lamin A, progerin, and HP1 in protein isolated from PBL. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To assess changes in leptin levels, glucose utilization, skeletal abnormalities including bone mineral density and X-ray finding, joint contracture and function, and growth [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To assess changes in auditory function, dental anomalies, dermatologic changes including hair density, nutrition with calorie analysis and energy expenditure, body composition analysis by DXA scan, and cardiovascular structure and function. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
- To compare and incorporate clinical and laboratory data obtain from this study with that obtained during the single agent lonafarnib trial as well as the pilot combination trial of zoledronic acid, pravastatin and lonafarnib [ Time Frame: 2 years ] [ Designated as safety issue: No ]
|Study Start Date:||August 2009|
|Estimated Study Completion Date:||June 2017|
|Estimated Primary Completion Date:||June 2017 (Final data collection date for primary outcome measure)|
Drug: Lonafarnib, Zoledronic Acid, and Pravastatin
Lonafarnib: Lonafarnib dosing will begin at 150 mg/m2 by mouth twice daily. Lonafarnib will be orally administered without planned breaks, approximately every 12 hours, for a period of 24 months. For patients unable to swallow capsules, the capsules can be opened and dissolved into Ora Blend SF or Ora-Plus.
Zoledronic Acid: Zoledronic acid will be administered intravenously at week one, and months 6, 12, 18 and 24 of this treatment trial. Treatment will consist of one infusion over a 30 minute period.
Pravastatin: Pravastatin will be orally administered once daily without planned breaks, approximately every 24 hours, for a period of 24 months. The drug may be taken with meals. For patients unable to swallow pills, pills can be crushed into food. Pravastatin will be dosed according to the patient weight. Patients less than 10 kg will receive 5 mg pravastatin orally, once daily. Patients weighing 10 kg or greater will receive 10 mg pravastatin daily.
