Intravenous Ascorbic Acid Supplementation in Neoadjuvant Chemotherapy for Breast Cancer

June 25, 2018 updated by: Pop Catalin Florin, MD, Academic Emergency County Hospital Sibiu

Phase I/II Randomized Study to Evaluate the Role of Intravenous Ascorbic Acid Supplementation to Conventional Neoadjuvant Chemotherapy in Women With Breast Cancer

Forty years ago clinical studies conducted by Ewan Cameron and Linus Pauling suggested that intravenous (IV) and oral ascorbic acid (AA) may diminish symptoms and could improve survival in terminal cancer patients. Previous phase I and II clinical trials have found that high dose (1.5g/kg ) iv AA is well tolerated in cancer patients. This is a phase I/II, randomized study of parenteral administration of Ascorbic Acid (AA) as a supplement to the conventional neo-adjuvant chemotherapy in women with breast cancer.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Vitamin C Supplement

Ascorbic Acid (AA) with neoadjuvant chemotherapy. Participants received an initial loading dose of 1,5 g Ascorbic Acid (i.v in 100 ml sterile water) on Day 1 followed by 0,75g Ascorbic Acid (i.v in 100 ml sterile water) on Day 2-4 at each chemotherapy cycle and concomitant neoadjuvant chemotherapy regimens administered at the choice of treating physician.

Ascorbic Acid is administered intravenously before neoadjuvant therapy in D1

1,5 g ascorbic acid dissolved in 100 ml sterile water, and 0,75 g ascorbic acid dissolved in 100 ml sterile water.
Other Names:
  • Chemotherapy
  • Vitamin C
Active Comparator: Placebo

Placebos (normal saline (0.9%) with neoadjuvant chemotherapy. 100 ml normal saline 0.9% (placebo) will be administered (i.v) by the same scheme as Ascorbic Acid on Day 1 and respectively Day 2-4 at each chemotherapy cycle.

Concomitant neoadjuvant chemotherapy regimens administered at the choice of treating physician.

100 ml normal saline 0.9%
Other Names:
  • Normal Saline
  • Saline 0.9%
