Peripheral Neuropathy Due to Chemotherapy

IncobotulinumtoxinA (Xeomin®, Merz) (INA) will be reconstituted with preservative-free normal saline to a dilution of 5mL:100 units. Study participants will receive 50u INA (total volume 2.5mL) injected into each limb, max 2 limbs per subject (either bilateral hands or bilateral feet.) Study participants will receive one series of injections during the trial. In the hands, INA will be injected across the palmar surface of the digits in a grid like pattern covering a total of 25 sites per limb (0.1mL/site). In the feet, INA will be injected across the dorsal surface of the foot in a grid like pattern covering a total of 25 sites per limb (0.1mL/site). Injections will be performed intradermally using a 5/16-inch, 32-g needle

Botulinum Toxin A for the Treatment of Chemotherapy Induced Peripheral Neuropathy

The primary outcome of this study will be the change pain as measured by the NPS at 8 weeks post intervention as compared to baseline NPS scores. The NPS is a validated scale that is used to classify patient's neuropathic pain. It includes assessment of global pain intensity and pain unpleasantness, two items addressing the location of the pain as deep or surface, and six items addressing the specific qualities of neuropathic such as sharp, hot, dull, cold, sensitivity, and itchy.

Change pain as measured by the NPS at additional time points: 2weeks, 4 weeks, 12 weeks, 6 months when compared to baseline scores.

Change in the pain characteristics as measured by each NPS domain when compared to baseline at additional time points: 2weeks, 4 weeks, 8 weeks, 12 weeks, 6 months. Domains include: assessment of global pain intensity and pain unpleasantness, two items addressing the location of the pain as deep or surface, and six items addressing the specific qualities of neuropathic such as sharp, hot, dull, cold, sensitivity, and itchy.

Change in the Neuropathic Pain Impact on Quality of Life (NePIQoL) score at time points: 2 weeks, 4 weeks, 8 weeks, 12 weeks, 6 months. The NePIQoL is a validated scale comprised of 42 items organized into 7 categories of questions affecting quality of life: symptoms, relationships, psychological, social activity, physical change, personal care, overall health and overall quality of life
