Clinical Trial Summary

Several open-label studies reported thalidomide efficacy in inducing clinical remission and steroid tapering in refractory Inflammatory Bowel diseases (IBD), both in adults and in children.

This is a randomized placebo controlled (RCT) double blind study, to evaluate the efficacy of thalidomide in inducing clinical remission at 8 weeks in refractory IBD patients aged 2-20 years.

The primary hypotheses of the study is that thalidomide would be more effective than placebo in inducing clinical remission.

The RCT phase is followed by a open-label phase, to further evaluate efficacy and safety of thalidomide in thalidomide responders, with a total follow up of one year.

Description:

Inflammatory bowel diseases (IBD) are particularly debilitating. They present chronic-recurrent symptoms which often seriously affects the patient's quality of life, acute complications which may need surgical interventions and long-term risks as evolution in cancer for ulcerative colitis.

Although onset is most common in the third decade of life, more than one third of IBD cases are diagnosed before age sixteen, and these younger patients, especially with Crohn's disease, are increasing in Western countries. Recent studies in the United Kingdom, Sweden and the United States report an incidence of 5-7 new cases of IBD every year per 100,000 subjects < 16 years of age, with an increasing trend over the last two decades.

IBD-related morbidity causes special concern in childhood-onset cases, since the disease can compromise height and weight development. This is even worsened in patients with poor disease control, which need steroid treatment in multiple courses and/or for a long period of time.

There are various drugs and treatments available for the management of IBD, but some patients, during the course of the illness, become resistant to conventional treatment, or develop serious adverse effects to immunosuppressive drugs.

A particular challenge is represented by those patients (especially children) who fail to respond to conventional treatment, or are steroid-dependent, or suffer from serious side effects from steroids use.

Thalidomide was first marketed in the early 1960s as a sedative drug and sadly gained notoriety because of its teratogenic effect. After few years from this tragedy, thalidomide was rediscovered both as an immunomodulator and as an anti-inflammatory drug, with anti tumor necrosis factor-alfa properties.

Thalidomide is now approved for the treatment of multiple myeloma and erythema nodosum leprorum. It has also been tested, with beneficial effects, in a variety of inflammatory diseases, especially those involving the skin and mucous membranes: recurrent aphthous stomatitis, oral and oesophageal ulcers in HIV, oral and genital ulcers and intestinal symptoms in Behcet's syndrome, graft versus host disease, skin manifestations in systemic lupus erythematosus, sarcoidosis, and tuberculosis. In these diseases, especially in those cases resistant to conventional treatments, thalidomide seems to have a promising role as a secondary therapeutic option.

The safety and efficacy of thalidomide in IBD has been recently evaluated in several open-label studies both adults and children, some of which with a long-term follow up. A total of approximately 200 patients with steroid-resistant or steroid-dependent IBD were treated with thalidomide. Overall, the drug was effective in inducing clinical remission in 20-70% of patients (average of 40%). 60-100% patients (average of 70%) had some clinical response. Steroid-tapering was possible in 60-100% of cases.

The most frequent side effect of thalidomide in IBD cases was neuropathy, which mainly reported as cumulative dose-dependent. Other possible side effects are constipation, sedation, dermatitis, mood disturbance, vertigo, cephalea, hypertension, hormonal alterations.

In the experience of our center, thalidomide was effective in achieving clinical remission in several children, adolescents, and young adults with intractable IBD. From 1998 to 2004 twenty-eight patients with refractory moderate-severe IBD (19 CD, 9 UC) received thalidomide 1.5-2.5 mg/kg/day. Remission was achieved with thalidomide in 21 of 28 (75%) patients (17 with CD, 4 with UC). Mean duration of remission was 34.5 months. Sixteen of 20 (80%) patients suspended steroids. Reversible neuropathy occurred in seven of 28 (25%) patients, but only with cumulative doses over 28 g. Other side effects requiring thalidomide suspension were vertigo/somnolence (one case), and agitation/ hallucinations (one case).

The aim of this study is to evaluate the efficacy of thalidomide therapy in children, adolescents and young adults with refractory Crohn's disease (CD) and ulcerative colitis (UD), with a total follow up of one year.

The study is divided in two phases:

• Phase I: randomized placebo controlled double blind study, to evaluate efficacy of thalidomide in refractory IBD patients, at 8 weeks.

• Phase II: open-label study, to evaluate efficacy and safety of thalidomide in patients responders to Thalidomide in Phase I, with a total follow up of one year.

Analysis will be stratified for Crohn's disease and ulcerative colitis. Given the hypotheses that thalidomide will be effective in inducing clinical remission at 8 weeks in 60% of patients with Crohn's disease, and 55% of patients with ulcerative colitis, compared to 20% of patients with placebo, with a significance of 0.05% and a power of 80%, estimated needed sample size is of 124 patients.
