Efficacy Study of Apremilast (CC-10004) in Subjects With Erosive Hand Osteoarthritis

A Phase 2, Multicenter, Randomized, Doubleblind, Placebo-controlled, Parallel-group,Efficacy Study of Apremilast (CC-10004)in Subjects With Erosive Hand Osteoarthritis

STUDY DESIGN:

This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group, efficacy and safety study in 30 patients with erosive osteoarthritis of interphalangeal joints. The study is composed of 4 phases: a pre-randomization phase for up to 35 days followed by a 91-day randomized, double-blind two arm treatment phase, followed by a 77-day open label treatment phase for all study participants and a 28-day observational follow-up phase. Efficacy of the double blind and open label phase will be assessed at study day 84 and 168 after treatment start respectively.

STUDY DURATION:

The study length will be approximately 231 days for individual patients. With approximately a 12 month recruitment period the study is planned to last from January 2010 until July 2011 (19 months).

STUDY OBJECTIVES:

The primary objective is to evaluate the 84-day efficacy of apremilast 20 mg twice per day [BID], subsequent to a 7-day dose titration, compared with placebo, for the treatment of the symptoms of erosive hand osteoarthritis. Further objectives are to evaluate the effects on pain, disease activity, structural damage, quality of life, safety and tolerability.

Description

Inclusion Criteria:

• Must have at least two bone erosions detectable in conventional radiographs of the hands at the first carpo-metacarpal joint (CMC), proximal and/or distal interphalangeal joints
• Must have active disease at screening and randomization with at least two swollen and tender PIP and/or DIP joints; with the same two joints affected at both screening and randomization.
• Must have a patients self assessment of pain at baseline of at least 40% on a VAS
• Must have negative rheumatoid factor (RF) and anti-CCP antibody
• Must be able to adhere to the study visit schedule and other protocol requirements
• Male subjects (including those who have had a vasectomy) must agree to use barrier contraception (latex condoms) when engaging in reproductive sexual activity with Females of Childbearing Potential (FCBP)while on study medication and for at least 28 days after taking the last dose of study medication
• Females of childbearing potential (FCBP) must have a negative urine pregnancy test at Screening and Baseline and must be willing to use one highly-effective form of birth control when engaging in reproductive sexual activity while on study medication and for at least 28 days after taking the last dose of study medication (§ A female of childbearing potential is a sexually mature female who 1) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for at least 24 consecutive months (ie, has had menses at any time during the preceding 24 consecutive months).

Must meet the following laboratory criteria:

Exclusion criteria:

• History of any clinically significant cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal, hematologic, immunologic, or other major diseases

• History or Diagnosis of Fibromyalgia
• Evidence of gout, pseudogout or hemochromatosis
• Any injury, medical or surgical procedure to the affected joint(s) that may interfere with evaluation of the target hand OA joint(s)
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study
• Pregnant or lactating female
• History of active Mycobacterium tuberculosis infection within 3 years prior to the screening visit. Infections that occurred > 3 years prior to entry must have been effectively treated
