Condition(s) targeted: Cancer; Pain

Intervention: oxycodone (Drug); pregabalin (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: Associazione Progetto Oncologia UMAN.A

Official(s) and/or principal investigator(s):
Gabriella Farina, MD, Principal Investigator, Affiliation: Fatebenefratelli and Ophtalmic Hospital


The aim of the study is to assess tolerability and activity of oxycodone and pregabalin in combination for the treatment of oncological neuropathic pain with two different strategies.

Clinical Details

Official title: Randomized Phase II Trial Evaluating Activity and Tolerability of Fixed Dose of Oxycodone and Increasing Dose of Pregabalin Versus Increasing Dose of Oxycodone and Fixed Dose of Pregabalin for the Treatment of Oncological Neuropathic Pain

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Achievement of analgesia (decrease of at least 1/3 of pain intensity) assessed by NRS scale

Secondary outcome:

Pain control rate

Reduction of Break Through Pain number

Record of adverse events

Reduction of allodynia in patients presenting it at T0

Patient satisfaction

Assessing whether COMT and mu blood polymorphisms are associated to response

Detailed description: Neuropathic pain is frequently diagnosed as a complication of cancer pain. While opioids are the mainstay of cancer pain management,their efficacy in neuropathic pain seems to be less then optimal,and adjuvant drugs, mainly anticonvulsants and antidepressants,are often combined with opioids in the analgesic regimen of patients with neuropathic cancer pain. This approach is suggested by well-established guidelines, but the analgesic benefit and the safety of pregabalin and oxycodone in combination is not yet documented. The aim of this study is to assess the activity and tolerability of the addition of pregabalin to oxycodone in the treatment of patients with neuropathic pain due to neoplasm.
