Fasting Mimicking Diet (FMD) in Conjunction With Chemotherapy in Advanced Ovarian Cancer

Study Overview
=================
Brief Summary
-----------------
Rates of grade 3-4 toxicity with carboplatin and paclitaxel chemotherapy range 26-84%. Interventions to reduce toxicity are needed. Short term fasting protects against toxic effects of chemotherapy without decreasing efficacy. In a prospective clinical trial of breast cancer patients randomized to FMD or regular diet during chemotherapy, less antiemetic was required in the FMD group; radiographic and pathologic responses were better in this group. This trial tests whether platinum-taxane chemotherapy combined with a FMD in advanced and recurrent ovarian, fallopian tube and primary peritoneal cancer patients is associated with decreased toxicity and/ or improved tumor response to therapy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Carboplatin and paclitaxel with standard diet<br>Patients receive paclitaxel IV over 3 hours and carboplatin IV over 30 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6-10 cycles in the absence of disease progression or unacceptable toxicity. A standard diet is consumed throughout each cycle of therapy. | Drug: Carboplatin<br>* Given IV<br>Drug: Paclitaxel<br>* Given IV<br>Dietary Supplement: Standard diet<br>* Normal diet<br>|
| Experimental: Carboplatin and paclitaxel with fasting mimicking diet (FMD)<br>Patients receive paclitaxel IV over 3 hours and carboplatin IV over 30 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6-10 cycles in the absence of disease progression or unacceptable toxicity. A fasting mimicking diet (FMD) is consumed beginning 3 days prior to chemotherapy and on the day of chemotherapy (days -2, -1, 0 and 1 of each cycle). | Dietary Supplement: Fasting Mimicking Diet (Xentigen by L'Nutra)<br>* L-Nutra Xentigen is a product which will provide all the food to be consumed by subjects during 3 days prior to chemotherapy and for 24 hours after chemotherapy. Xentigen is a plant-based diet program designed to attain fasting-like effects while providing both macro- and micronutrients to minimize the burden of fasting and adverse effects. The FMD consists of 100% ingredients that are generally regarded as safe (GRAS) and comprises proprietary vegetable-based soups and broths, energy bars, energy drinks, cracker snacks, herbal teas, and supplements. The FMD consists of a 4-day regimen that provides approximately 1100 kilocalories for the first day and approximately 500 kilocalories per day for the second to the fourth day. Subsequently, a day 5 of transition diet (approximately 800 kilocalories) is provided to avoid the refeeding syndrome.<br>Drug: Carboplatin<br>* Given IV<br>Drug: Paclitaxel<br>* Given IV<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To determine whether the combination of standard of care platinum-taxane chemotherapy with a FMD compared to a regular diet is associated with decreased gastrointestinal (GI) toxicity in advanced and recurrent ovarian cancer patients. | Toxicities and adverse events will be graded and summarized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), v5.0 and will be compared between the two study groups. The following toxicity summaries will be used to compare the diet and non-diet group: Any of the following Grade 2+ GI symptomatic toxicities (nausea and vomiting, anorexia, constipation or diarrhea, mucositis, stomatitis) experienced. The NCI CTCAE has a specific scale (graded 1-5) for each toxicity which can be used objectively to compare different drug toxicities. | 6 months | 
| To determine whether the combination of standard of care platinum-taxane chemotherapy with a FMD compared to a regular diet is associated with decreased neurotoxicity in advanced and recurrent ovarian cancer patients. | Toxicities and adverse events will be graded and summarized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), v5.0 and will be compared between the two study groups. The following toxicity summaries will be used to compare the diet and non-diet group: Any Grade 2+ neuropathy experienced. The NCI CTCAE has a specific scale (graded 1-5) for each toxicity which can be used objectively to compare different drug toxicities. | 6 months | 
| To determine whether the combination of standard of care platinum-taxane chemotherapy with a FMD compared to a regular diet is associated with decreased hematologic toxicity in advanced and recurrent ovarian cancer patients. | Toxicities and adverse events will be graded and summarized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), v5.0 and will be compared between the two study groups.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To describe the safety and tolerability of a concurrent FMD, including patient compliance to diet, with platinum-taxane chemotherapy in advanced and recurrent ovarian cancer patients. | Safety will be assessed by measuring and comparing adverse events experienced by patients in each study group. This study will utilize the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 to describe and quantify study subject adverse events. In addition the number of patients that do not complete the FMD during chemotherapy will be recorded. The number of cycles completed with the FMD for each patient in the FMD group will be recorded to determine compliance with the regimen. | 6 months |

| To compare tumor pathologic response to therapy in advanced ovarian cancer patients treated with the combination of platinum-taxane chemotherapy and a FMD versus a regular diet. | Tumor pathologic response in the primary (neoadjuvant) treatment group will be measured using a 3-tier chemotherapy response score (CRS). CRS is assigned on a scale of 1-3 with 3 representing the most complete response to treatment (ie best response) and 1 representing the least robust response to treatment (ie worst response). | 6 months |
