SB497115/Placebo will be administered for at least 2 cycles. Additional cycles are permited if: 1) chemotherapy is continued, 2) the subject appears to be benefitting from the study drug, and 3) the subject has not encountered greater than moderate toxicity with the study drug. The maximum number of cycles would be 8.

GSK Clinical Trials

SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 versus placebo as treatment for patients with advanced solid tumors scheduled to receive chemotherapy with carboplatin and paclitaxel every 21 days. Patients will receive SB497115 on days 2-11 of each 21 day cycle for at least 2 cycles of chemotherapy and for a maximum of 8 cycles of chemotherapy.

The objective of this observational study is to evaluate the effectiveness of the dietary supplementation "OnLife" in improving signs and symptoms of chemotherapy-induced peripheral neuropathy (CIPN) in adult patients who have finished adjuvant oxaliplatin-containing regimen (colon cancer) or adjuvant paclitaxel regimen (breast cancer). Furthermore, patient-reported outcomes (PROs) and concomitant medication used for the treatment of neuropathic pain will be assessed.

CIPN is a common side effect of many chemotherapeutic agents and often results in dose limitation, switch to less efficacious agents or even therapy discontinuation. CIPN mainly affects sensory nerves, while motor or autonomic nerve injury is rare. Therefore, most patients with CIPN experience numbness, tingling, hyperesthesia, loss of vibratory perception, and burning pain. Due to the vulnerability of the long nerves, CIPN typically appears in a 'stocking and glove' distribution.

Chemotherapeutic agents that cause CIPN include platinum compounds (e.g., cisplatin, oxaliplatin), antitubulins (vinca alkaloids (e.g., vincristine) and taxanes (e.g., docetaxel, paclitaxel)), proteasome inhibitors (e.g., bortezomib) and immunomodulatory drugs (e.g., lenalidomide).

Platinum compounds are known to accumulate in the dorsal root ganglion (DRG) leading to cell death in sensory neurons. DRG death may account for chronic sensory neuropathy, which manifests primarily as sensory paresthesias, dysesthesias and sensory ataxia most often located in the extremities and persists between cycles. In addition, Oxaliplatin directly regulates the gating of axonal voltage-gated sodium channels, inducing an acute neurotoxicity which is characterized by peripheral nerve hyperexcitability. Symptoms, like sensitivities to touching cold items, discomfort swallowing cold liquids, throat discomfort, and muscle cramps, occur during or shortly after the infusion.

Taxanes are known to cause disruption of microtubule function and therefore microtubule-based axonal transport. In addition, they interfere with macrophage activation in both the DRG and peripheral nerve, as well as microglial activation within the spinal cord. These effects result in a distal axonopathy also referred to as the dying-back phenomenon.

The effectiveness of OnLife® in improving CIPN is based on a patented fatty acid group (FAG) that comprises palmitoylethanolamide (PEA), alpha-linolenic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), linoleic acid, oleic acid, palmitic acid, stearic acid, arachidic acid and myristic acid.

PEA, one main component of OnLife®, is an endogenous fatty acid amide belonging to the class of endocannabinoids and has been shown to have anti-inflammatory, antinociceptive, neuroprotective and anticonvulsant properties. It is synthesized in response to several inflammatory and painful disorders (e.g., intestinal inflammation and neuropathic pain) in order to counteract these pathological states. Clinical research revealed that treatment with exogenous PEA is effective and safe in various neuropathological conditions, including chronic idiopathic axonal neuropathy, diabetic neuropathy, nerve compression syndromes, as well as chemotherapy-induced neuropathic pain.

PEA exerts its analgesic and anti-inflammatory functions in the peripheral nervous system through its action on sensory neurons and on non-neuronal cells involved in inflammation, such as mast cells and macrophages. It indirectly activates cannabinoid receptor signaling by inhibiting the hydrolysis of endocannabinoids. This suppresses nociceptive behaviors and counteracts macrophage and mast cell activation, thereby reducing pain and other inflammatory symptoms. Another biological target of PEA is the nuclear peroxisome proliferator-activated receptor (PPAR)-alpha, expressed in various cells implicated in peripheral nociception, including dorsal DRG neurons and macrophages. Binding of PEA to PPAR-alpha ultimately results in reduced transcription of pro-inflammatory genes (e.g., TNF-alpha, IL-6, COX-2, iNOS) as well as repressed activity of pro-inflammatory transcription factors. In addition, there is some evidence that binding of PEA to PPAR-alpha may modulate excitability of primary sensory neurons by direct and indirect mechanisms.

The other fatty acids included in OnLife® have also been shown to have anti-inflammatory properties.

Currently, a study evaluating the efficacy and safety of OnLife® in patients with CIPN is carried out at the St. Savvas Anticancer Hospital, Athens by Dr. J. Skarlatos. First results suggest that OnLife® is reducing pain, numbness and tingle and improving heat/cold sensitivity as assessed by the physician. PRO, using the DN4 (Douleur Neuropathique 4) questionnaire, revealed a reduction of the score for diagnosing neuropathic pain during OnLife® application. Moreover, no patient showed a product-related side effect (date on file, unpublished).
