Safety and Preliminary Evidence of Efficacy of Escalating Doses of Dimiracetam in AIDS Patients With Painful Neuropathy

June 1, 2010 updated by: Neurotune AG

A Double Blind, Parallel-group, Randomized Placebo Controlled, Multicentre Exploratory Study of Dimiracetam in Treatment Induced Painful Neuropathy in Patients With HIV Infection

One hundred consenting AIDS patients suffering from treatment induced painful neuropathy will be blindly randomize to Active and Placebo groups (ratio A/P = 3/2 and will receive increasing oral doses of dimiracetam starting from 400 mg b.i.d. and doubling the dose every two weeks until a maximum of 1600 mg b.i.d. Escalation to the the higher dose is allowed only if the previous dose did not cause tolerability problems. The highest reached dose will be maintained for a total of 8 week treatment. Patients must have a self evaluated pain of at least 4 on a 10 cm visual analog scale (VAS). Primary end point of the study will be the number of Adverse Events (AEs) reported in the placebo versus the active group. Preliminary evidence of efficacy will be sought by comparing active and placebo group as to the intensity of their pain at study onset and at study end. The pain will be evaluated by the VAS the Total Symptoms Score and the Clinical Global Impression

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Exclusion Criteria:

  • pregnant or lactating females;
  • patients with neuropathic pain due to other factors than the ARTs; any clinically significant underlying disease, according to the Investigator's clinical judgement;

  • any current axis I diagnosis including dementia, depression, psychosis, anxiety disorders, mental retardation;
  • participation in the evaluation of any investigational drug within 3 months prior to screening (6 months in the neuropathic pain). Use of an investigational drug other than dimiracetam during the study is not permitted;
  • treatment with neurostimulating devices such as spinal cord stimulation (SCS), acupuncture, homeopathic remedies for pain or any kind of surgical treatment or blockade for the pain in the 4 weeks prior to screening;
  • treatment with any drug for neuropathic pain (NP) after the screening visit; requirement of more than 2 transfusions / month to achieve haemoglobin level > 8 g/dL;
  • history of alcohol abuse (defined according to USDA dietary guidelines) or drug abuse during the last 3 months prior to screening;
  • history of allergic response to neuropathic treatments or history of anaphylaxis or allergic reactions to drugs in general;
  • any abnormality that the Investigator deems to be clinically relevant, either on medical history, physical examination, ECG or in diagnostic laboratory test;
  • subjects likely to be non-compliant or uncooperative during the study according to the Investigator or designee's judgement
