Trial Information

Phase I Study of Vorinostat in Combination With 13-Cis-Retinoic Acid in Patients With Refractory/Recurrent Neuroblastoma


PRIMARY OBJECTIVES:

I. To determine the maximum-tolerated dose of vorinostat in combination with isotretinoin in
patients with high-risk refractory or recurrent neuroblastoma.

II. To define the toxicities of vorinostat administered in combination with cisRA.

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetics of vorinostat given as a pediatric suspension.

II. To describe the relationship of vorinostat pharmacokinetics to the occurrence of
systemic toxicity.

III. To determine the pharmacokinetics of cisRA given in combination with vorinostat.

IV. To describe histone acetylation levels in peripheral blood mononuclear cells after
different doses of vorinostat.

V. To describe, within the context of a Phase I study, the response rate of vorinostat
combined with cisRA in patients with recurrent/refractory neuroblastoma.

VI. To describe the toxicity and response rate of vorinostat at the determined maximal
tolerated dose combined with cisRA in patients ages 22-30 years of age at study entry with
recurrent/refractory neuroblastoma.

OUTLINE: This is a multicenter, dose-escalation study of vorinostat.

Patients receive oral isotretinoin twice daily on days 1-14, oral suspension* of vorinostat
once daily on days 1-4 of course 1, and oral capsules of vorinostat once daily on days 1-4
and 8-11 of course 2 and subsequent courses. Treatment repeats every 28 days for up to 12
courses in the absence of disease progression or unacceptable toxicity.

EXPANSION COHORT 1 (≤ 21 years of age): Once the maximum-tolerated dose (MTD) has been
determined, patients are treated at that dose level as above.

EXPANSION COHORT 2 (22-30 years of age): Patients receive isotretinoin as above and
vorinostat at the MTD on days 1-3 and 8-10.

Treatment repeats every 28 days for up to 12 courses in the absence of disease progression
or unacceptable toxicity. Patients may undergo peripheral blood mononuclear cells collection
for pharmacokinetics and histone acetylation studies.

After completion of study therapy, patients are followed up periodically.

NOTE: *Patients less than 10 years of age are encouraged to continue to use oral suspension
beyond course 1.
