• Status: Withdrawn
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of the study is to determine whether the ability of MEK162 to antagonize MEK activation in NS HCM patients, who usually have upstream mutations in the Ras-Raf-Mek-Erk pathway that lead to MEK activation, would be beneficial over a 6 month treatment period in hypertrophy regression.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Array BioPharma; Array Biopharma, now a wholly owned subsidiary of Pfizer

Criteria

Inclusion:

• Male and female Noonan syndrome patients with confirmed cardiac hypertrophy, age 18 to 65 years of age included, and in general good health as determined by past medical history, physical examination, vital signs, electrocardiogram, and laboratory tests at screening.

• Cardiac hypertrophy is defined by left ventricular wall thickness greater than or equal to 12 mm by echocardiography or MRI, or the change in wall thickness is accompanied by an associated increase in left ventricular mass which is defined by echo or MRI as greater than 134 g/m2 and 110 g/m2 in men and women, respectively.

• Subjects must weigh at least 45 kg to participate in the study, and must have a body mass index (BMI) within the range of 18 - 34 kg/m2.

Exclusion criteria:

• Primary Long QT syndrome or a history of significant ECG abnormalities judged by the investigators to be inappropriate for participation in the current study.

• History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.

• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant.

• Sexually active males must use a condom during intercourse while taking the drug during treatment, for 5 half lives after stopping treatment and should not father a child in this period.

• Use of any prescription drugs other than beta-blockers, diuretics, CCB, amiodarone, disopyramide, herbal supplements, within four (4) weeks prior to initial dosing, and/or over-the-counter (OTC) medication, dietary supplements (vitamins included) within two (2) weeks prior to initial dosing. If needed, (i.e. an incidental and limited need) paracetamol or acetaminophen is acceptable, but must be documented in the Concomitant medications/Significant non-drug therapies page of the eCRF.

Other protocol-defined inclusion/exclusion criteria may apply.
