About this study

Official title: A Pilot Randomized, Placebo Controlled, Double Blind Study of Omega-3 Fatty Acids to Prevent Paclitaxel Associated Acute Pain Syndrome

Paclitaxel, a widely used chemotherapeutic agent, is associated with several well-known side effects including neuropathy (weakness, numbness and pain) and generalized body aches. The latter has recently been described as paclitaxel-associated acute pain syndrome (P-APS) and often occurs in the first three to four days after administration. It affects about 58-90% of patients. Currently, the mechanism of P-APS is unknown, and there is no standard of care to treat it. However, an intervention with both anti-inflammatory as well as neuroprotective properties would be an ideal candidate for testing in the prevention of P-APS and subsequent development of peripheral neuropathy. Previous studies have suggested that omega-3 fatty acids may act as neuroprotective agents, and there are no currently documented safety concerns with their combined use with paclitaxel.

Therefore, this randomized pilot clinical trial will determine whether omega-3 fatty acids can treat pain in patients with breast or ovarian cancer receiving paclitaxel.

Read the detailed description

One mechanism proposed for P-APS is an early inflammatory process characterized by macrophage activation in both the dorsal root ganglia and peripheral nerve occurring shortly after paclitaxel therapy. Morphologic alterations in DRG satellite cells have been noted and upregulation of proinflammatory cytokines have been hypothesized as early events in the development of neuropathy. Therefore, it is possible that paclitaxel-induced neuropathic pain may be mediated by pro-inflammatory cytokines. If P-APS and chronic neuropathy are indeed part of a continuum, the inflammatory pathway would be a reasonable target for therapy. While the mechanism of how paclitaxel leads to the development of neuropathy is still not understood, it has been hypothesized that its microtubule-stabilizing effects disrupt axonal transport. Intervention with an agent that is both anti-inflammatory as well as neuroprotective is therefore worth exploring.

Long chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are common dietary supplements. They have well established anti-inflammatory properties which serve as the basis for their use in therapeutic trials in inflammatory conditions. Omega -3 fatty acids consumption can attenuate the production of pro-inflammatory metabolites. In addition, it can generate local mediators that facilitate resolution of inflammation. Thus, if P-APS is indeed mediated by inflammation, the anti-inflammatory activity of omega 3 fatty acids may be one mechanism to prevent P-APS. Additionally, given its well established safety profile, it may be an attractive alternative to NSAIDS.

A dose of at least 2.7 g/day of EPA and DHA have been reported to have analgesic effects in inflammatory conditions. The dose of 4 g/day is an FDA-approved dose of omega 3 fatty acids (Lovaza) for the treatment of hypertriglyceridemia and has a well-documented toxicity profile. On the basis of this, a dose of 4 g/day was selected for this study. Lovaza (omega-3-acid ethyl esters) capsules will be used. Each 1-gram capsule contains approximately 465 mg EPA and 375 mg DHA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Omega-3 fatty acidDietary supplement

    Also called Fish oil, n-3 fatty acid, O3FA, Lovaza

    Patients receive omega-3 fatty acid capsules orally beginning 1 week prior to paclitaxel treatment.

    Capsule administration continues until paclitaxel is discontinued or for 12 weeks maximum (whichever comes first).

    Each 1-gram capsule contains approximately 465 mg eicosapentaenoic acid (EPA) and 375 mg docosahexaenoic acid (DHA).

  • PlaceboDietary supplement

    Patients receive placebo capsules orally beginning 1 week prior to paclitaxel treatment.

    Capsule administration continues until paclitaxel is discontinued or for 12 weeks maximum (whichever comes first)

  • PaclitaxelDrug

    Also called Taxol

    Patients will receive, as part of their standard of care, weekly paclitaxel at 70 to 90 mg/m2 intravenously for a minimum of 2 months. Treatment 3 out of 4 weeks is allowed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean severity of pain

    Differences between groups will analyzed via t-tests or Wilcoxon rank-sum tests as appropriate.

    Measured: Up to 1 month after completion of therapy

Secondary outcomes (1)
  1. Incidence of pain or relief

    Fisher's exact test will be used for the incidence variable with 95% confidence intervals.

    Measured: Up to 1 month after completion of therapy
