Brief Summary:
Patients with breast cancer are commonly treated with taxane chemotherapy. Some very common side effects of taxanes, such as anemia and peripheral neuropathy, are often as not well addressed during treatment, resulting in dose reductions, dose delays and early discontinuation (collectively called relative dose intensity) of these chemotherapy agents in 15-80 % of patients on these drugs. This reduction in relative dose intensity (RDI) results in worse clinical outcomes such as progression free and overall survival. Pre-clinical studies in mouse models subjected to standardized chemotherapy regimens containing paclitaxel or oxaliplatin have shown that the nutritional supplement Epidiferphane™ reduces both neuropathy and anemia. This study will investigate whether the use of Epidiferphane™ in patients with breast cancer receiving taxane chemotherapy results in an attenuation of the side effects experienced, as well as an improvement in tumor response rate. The safety and maximum tolerated dose of Epidiferphane™ in this patient population will also be determined in this study.

Arm Intervention/treatment
Experimental: Epidiferphane + taxane chemotherapy Drug: Epidiferphane

During the phase I portion of the study, subjects will be assigned to take either two (half target dose) or four (full target dose) Epidiferphane tablets orally three times daily following a 3 + 3 design. Three subjects will be sequentially enrolled at each of the 2 dose levels (beginning with the half target dose) until at least one dose-limiting toxicity (DLT) occurs. Dosing escalation will be stopped if two or more DLTs occur at either dose level. The maximum tolerated dose will be one dose level lower than the dose level at which 2 or more DLTs occur. Dose escalation will occur separately for each of the two taxane regimens (weekly paclitaxel or docetaxel every 3 weeks).

All subjects in the phase II portion of the study will receive the maximum tolerated dose determined in the phase I portion of the study for their taxane regimen.

Subjects in both portions of the study will receive treatment with Epidiferphane for a maximum of three months.


Drug: Taxane Chemotherapy
All subjects on both phases of the study will be concurrently treated with a taxane regimen containing either paclitaxel given weekly or docetaxel given every 3 weeks. The choice of taxane regimen will be determined by the treating physician prior to consenting to participate in this trial.




Primary Outcome Measures :
  1. Cmax of Epidiferphane's components [ Time Frame: 24 hours ]

    The Cmax of each of Epidiferphane's components will be based on blood concentration measured prior to taxane chemotherapy administration, as well as at 1, 2 and 24 hours after taxane chemotherapy administration.

    The Cmax of each of Epidiferphane's components will be the blood concentration measured prior to taxane chemotherapy administration, as well as at 1, 2 and 24 hours after taxane chemotherapy administration.


  2. Cmax of taxanes [ Time Frame: 24 hours ]
    The Cmax of the taxane chemotherapy agents given will be based on blood concentrations measured prior to taxane chemotherapy administration, as well as at 1, 2 and 24 hours after taxane chemotherapy administration.

  3. Concentration at 24 hours (C24 hours) of Epidiferphane's components [ Time Frame: 24 hours ]
    The C24 hours of each of Epidiferphane's components will be based on blood concentration measured 24 hours after taxane chemotherapy administration.

  4. Concentration at 24 hours (C24 hours) of taxanes [ Time Frame: 24 hours ]
    The C24 hours of the taxanes given will be based on blood concentration measured 24 hours after taxane chemotherapy administration.

  5. Maximum tolerated dose of Epidiferphane in patients with breast cancer who are being treated with taxanes [ Time Frame: 4 months ]
  6. Change in Common Terminology Criteria for Adverse Events (CTCAE) v5.0 grade 2 or higher neuropathy [ Time Frame: 4 months ]
  7. Change in Common Terminology Criteria for Adverse Events (CTCAE) v5.0 grade 1 or higher anemia [ Time Frame: 4 months ]

Secondary Outcome Measures :
  1. Effect of Epidiferphane on quality of life, as measured by the EORTC QLQ-C30 scale [ Time Frame: 3 months ]
    The EORTC QLQ-C30 measures ability to perform everyday activities and whether the subject has experienced select physical symptoms on a scale of 1-4 (with 1 meaning "Not at all" and 4 meaning "Very much"), as well as overall quality of life and overall healt over the past week on a scale from 1-7 (with 1 meaning "Very Poor" and 7 meaning "Excellent").

  2. Effect of Epidiferphane on quality of life, as measured by the FACT-Taxane scale [ Time Frame: 3 months ]
    The FACT-Taxane measures various aspects of physical, social, emotional, and functional well-being, as well as whether the subject has experienced select physical symptoms over the past 7 days, on a scale of 0-4 (with 0 meaning "Not at all" and 4 meaning "Very much").

  3. Tumor response rate [ Time Frame: 3 months ]
    Determine the effect of Epidiferphane on tumor response rate, as measured by RECIST (Response Evaluation Criteria in Solid Tumors) v1.1 criteria or pathologic tumor response at surgery

  4. Effect of Epidiferphane on the neuropathy marker NF-kB [ Time Frame: 3 months ]
  5. Effect of Epidiferphane on the neuropathy marker VEGFA [ Time Frame: 3 months ]
  6. Effect of Epidiferphane on the neuropathy marker Nrf2 [ Time Frame: 3 months ]
  7. Effect of Epidiferphane on the neuropathy marker IL18 [ Time Frame: 3 months ]
