Drug: thalidomide

Study type


Funder types



Details and patient eligibility



Patients with chronic hepatitis C, genotype 1 and non-responders to standard treatment for hepatitis C.


  1. ascertain the rate of sustained response in patients with hepatitis C, genotype 1 with peginterferon + ribavirin resistance.
  2. To know the response rate in 12 weeks
  3. Describe the tolerance and safety of thalidomide in combination with peginterferon and ribavirin.


The single arm study will:

  1. Thalidomide 200 mg and peg-interferon alfa 2b (based on weight: 50-120 mcg / week) + ribavirin (based on weight: 1000-1200mg / day)

Be tracked for 24 weeks after treatment.

Suspended treatment of 12 weeks in patients who have failed a drop of HCV RNA> 2 log.

Patients who have been suspended for any reason, the treatment will be followed during 24 weeks, to assess safety parameters.



10 estimated patients
