  Purpose

The purpose of this study is to compare the pharmacokinetic profile of midazolam given alone and midazolam given after multiple oral doses of 40 mg ridaforolimus.

Part 1 of this study is designed for evaluating CYP3A4 activity following 5 days of dosing of ridaforolimus and is not designed with efficacy endpoints. Part 2 is a compassionate-use extension to give patients an opportunity to receive a clinically active dose of ridaforolimus. Part 2 dosing is open ended with limited data collection.

Primary Outcome Measures:
  • Area Under the Concentration-time Curve (AUC [0-infinity]) of midazolam 2 mg administered alone versus when administered after multiple oral doses of ridaforolimus 40 mg. [ Time Frame: 8 days (Day -2 through Day 5, 24 hrs postdose) ] [ Designated as safety issue: No ]
  • Maximum Concentration (Cmax) of midazolam 2 mg administered alone versus when administered after multiple oral doses of ridaforolimus 40 mg. [ Time Frame: 8 days (Day -2 through Day 5, 24 hrs postdose) ] [ Designated as safety issue: No ]
  • Time to Cmax (Tmax) of a single oral dose of 2 mg midazolam administered alone versus when administered after multiple oral doses of ridaforolimus 40 mg. [ Time Frame: 8 days (Day -2 through Day 5, 24 hrs postdose) ] [ Designated as safety issue: No ]
  • Apparent terminal half-life (t½) of a single oral dose of 2 mg midazolam administered alone versus when administered after multiple oral doses of ridaforolimus 40 mg. [ Time Frame: 8 days (Day -2 through Day 5, 24 hrs postdose) ] [ Designated as safety issue: No ]

Enrollment: 16
Study Start Date: March 2010
Study Completion Date: February 2012
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: All Participants
In Part 1, all participants received a single oral dose of 2 mg midazolam on Day -2. On Days 1-5, all participants received daily single oral doses of ridaforolimus 40 mg ( 4 x 10 mg tablets). On Day 5, all participants received a single oral dose of 2 mg midazolam coadministered with the dose of ridaforolimus. Participants had the option to continue into Part 2 of this study.
Drug: Midazolam
A single oral dose of midazolam 2 mg (1 mL of 2 mg/mL syrup) was given on Day -2 and Day 5.
Drug: Ridaforolimus
Ridaforolimus 40 mg (4 x 10 mg tablets) oral once daily on Days 1 through 5.

Criteria

Inclusion Criteria:

  • participant is male or female

standard therapy does not exist. There is no limit on the number of prior treatment

regimens

  • participant must have a performance status of ≤ 2 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale

year and follicle stimulating hormone (FSH) is in the postmenopausal range at screening), surgically sterilized

(hysterectomy, oophorectomy or tubal ligation) or, if of childbearing potential, must

be willing to use 2 approved methods of contraception (hormonal contraception,

intra-uterine device, diaphragm with spermicide, cervical cap with spermicide or

female condom with spermicide; spermicides alone are not an acceptable method of

contraception) from screening until 30 days following the last dose of study drug.

  • If participant is female and of childbearing potential, she must have a negative serum β-

human chorionic gonadotropin (hCG) pregnancy test at screening and within 24 hrs prior to dosing Part 1/Day -2

  • If participant is male and has female partner(s) of child-bearing potential, he must agree

to use a medically acceptable method of contraception during the study and for 30

days after the last dose of study drug. If the participant's partner is pregnant, the participant

must agree to use a condom. If the participant's partner is of child-bearing potential, he

must use a condom and his partner must additionally use one of the following

methods: hormonal contraception, intra-uterine device, diaphragm with spermicide,

cervical cap with spermicide or female condom with spermicide.
