Finding an Effective Dose of GM1 to Reduce or Prevent Neuropathy (Numbness or Weakness) Due to Treatment With Paclitaxel (Phase II)

Description

PRIMARY OBJECTIVES:

I. To obtain data to further support the safety of increasing monosialotetrahexosylganglioside (GM1) doses when given on day 1, concomitantly with paclitaxel. (Early phase) II. To evaluate the preliminary efficacy of GM1 compared with placebo at preventing paclitaxel-induced peripheral neuropathy sensory symptoms as measured by the six individual Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 (QLQ-CIPN20) questions that quantify numbness (N), tingling (T), and pain in the fingers/hands and toes/feet. (Phase II)

SECONDARY OBJECTIVES:

I. To obtain additional data to support the safety of GM1 in the treated population. (Phase II) II. To obtain data to support that GM1 looks promising for preventing/decreasing acute paclitaxel pain syndrome as measured by the Acute Pain Syndrome Questionnaire. (Phase II)

EXPLORATORY OBJECTIVES:

I. Conduct of this clinical trial provides the opportunity to facilitate the better understanding of the natural history of paclitaxel-induced neuropathy, akin to what is being examined in a currently active trial, S1714. (Phase II) II. This clinical trial also provides an opportunity to conduct correlative studies to understand the mechanism of CIPN and/or identify biomarkers of CIPN or GM1 efficacy. (Phase II) III. To obtain efficacy data to assess the impact of GM1 on the anti-tumor activity of paclitaxel as evaluated by progression-free survival and overall survival. (Phase II)

OUTLINE: This is an early phase dose-escalation study of GM1 followed by a phase II study.

EARLY PHASE: Patients receive GM1 intravenously (IV) over 1 hour either once every 7 days, or once every 7 days for 3 doses followed by one week off, prior to paclitaxel administration.

PHASE II: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive GM1 IV 1 hour prior to paclitaxel administration and paclitaxel IV weekly for 12 weeks or 3 weeks on/1 week off for 12 doses.

ARM II: Patients receive placebo IV 1 hour prior to paclitaxel administration and paclitaxel IV weekly for 12 weeks or 3 weeks on/1 week off for 12 doses.
