Sponsor:

Cedars-Sinai Medical Center

Information provided by (Responsible Party):

Shlomo Melmed, MD

Brief Summary:

This phase 2 multicenter, open-label clinical trial will evaluate safety and efficacy of 4 weeks of oral seliciclib in patients with newly diagnosed, persistent, or recurrent Cushing disease. Funding Source - FDA Office of Orphan Products Development (OOPD)

Condition or disease

Intervention/treatment

Seliciclib

Phase

PHASE2

Detailed Description:

This phase 2 multicenter, open-label clinical trial will evaluate safety and efficacy of oral seliciclib in patients with newly diagnosed, persistent, or recurrent Cushing disease. Up to 13 subjects will be treated with 80 mg each day for 4 weeks. The study will also evaluate effects of seliciclib on quality of life and clinical signs and symptoms of Cushing disease.

If a woman is participating in the trial then one form of contraception is sufficient (pill or diaphragm) and the partner should use a condom. If oral contraception is used in addition to condoms, the patient must have been practicing this method for at least two months prior to screening and must agree to continue the oral contraceptive throughout the course of the study and for 3 months after the study has ended. Male patients who are sexually active are required to use condoms during the study and for three months afterwards as a precautionary measure (available data do not suggest any increased reproductive risk with the study drugs)

        • * Patients with prolonged QTcF on screening electrocardiogram (QTcF \>450 msec)
