Fasting Mimicking Diet Program to ImpRovE ChemoTherapy in Hormone Receptor Postive (HR+), HER2- Breast Cancer (DIRECT-2)

DIRECT-2: Fasting Mimicking Diet Program to ImpRovE ChemoTherapy in HR+, HER2- Breast Cancer

In preclinical research, short-term fasting (STF) protects tumor-bearing mice against the toxic effects of chemotherapy, improves the CD8+ effector T-cell intratumor infiltration, while enhancing the chemotherapy efficacy. Short-term use of a "fasting-mimicking diet" (FMD) caused a major increase in the efficacy of cancer treatment in mice comparable to STF. In humans, the investigators recently performed a multicenter randomized phase II trial showing that patients with Human Epidermal growth factor Receptor 2 (HER2) negative breast cancer treated with neoadjuvant chemotherapy and FMD displayed a better radiological response and a better pathological response (90-100% vs <90% tumor cell reduction) than patients treated with chemotherapy without FMD (de Groot, Nat Commun 2020; NCT02126449). Therefore these findings will be validated in a phase 3 trial with the underlying hypothesis that FMD during neoadjuvant chemotherapy for breast cancer improves clinical outcomes, potentially due to improved local immunity.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Fasting Mimicking Diet group
Fasting Mimicking Diet 3 days before and the day of neoadjuvant chemotherapy (ddAC, T)
Fasting mimicking diet by L-Nutra, a 4-day low caloric, low protein, vegetarian diet 3 days prior to and the day of neoadjuvant chemotherapy administration. The FMD will take place every 4 weeks, thus in total 5 times (2x during ddAC, 3x during Paclitaxel) during the neoadjuvant chemotherapy.
Other Names:
  • Xentigen™
No Intervention: Normal Diet group
Standard neoadjuvant chemotherapy (ddAC, T)
