About

The goal of this study is to determine whether a significant pharmacokinetic interaction exists between rapamycin and sorafenib.

This study will also look at the toxicity of the combination of rapamycin and sorafenib and the antitumor activity of the combination in subjects with advanced cancers.

Enrollment: 34 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

  • total bilirubin less than or equal to 1.5 x ULN
  • creatinine less than or equal to 1.5 x ULN

34 participants in 4 patient groups

A

Experimental group

Description:

Sorafenib two times a day every day for 28 days. Beginning on Day 15 (Week 2), rapamycin will be taken once a week until the end of the cycle (Day 28). After Day 28, weekly rapamycin and daily sorafenib will continue until disease progression or serious side effects are experienced.

Treatment:

Drug: Sorafenib

Drug: Rapamycin

Drug: Rapamycin

B

Experimental group

Description:

Sorafenib two times a day every day for 28 days. Beginning on Day 15 (Week 2), rapamycin will be taken every day until the end of the cycle (Day 28). After Day 28, rapamycin and sorafenib can continue to be taken daily until the cancer gets worse or serious side effects are experienced.

Treatment:

Drug: Sorafenib

Drug: Rapamycin

C

Experimental group

Description:

Rapamycin once a week starting on Day 1. Beginning on Day 15 (Week 2), sorafenib will be taken twice a day every day until the end of the cycle (Day 28). After Day 28, weekly rapamycin and daily sorafenib will continue until disease progression or serious side effects are experienced.

Treatment:

Drug: Sorafenib
