Purpose:

This pilot phase I trial studies the safety of long-term use of sodium bicarbonate in patients with cancer. Sodium bicarbonate may neutralize tumor acidity and as a result may inhibit the spread of the tumor to other parts of the body (metastases) and improve survival.


Study summary:

PRIMARY OBJECTIVES: I. Determine if the dose concentration of 0.5 g/kg/day sodium bicarbonate is feasible and well tolerated as measured by the proportion of subjects with first evidence of adherence failure. SECONDARY OBJECTIVES: I. Determine if the dose concentration of 0.5 g/kg/day sodium bicarbonate is safe for long term consumption (90 days) as measured by blood pressure, resting pulse rate, and basic metabolic panels to assess metabolic alkalosis. OUTLINE: PHASE I (RUN-IN/ADJUSTMENT): Patients receive sodium bicarbonate orally (PO) dissolved in water thrice daily (TID) or twice daily (BID) on days 1-10. The dose may be adjusted as necessary. PHASE II (LONG TERM): Patients continue to receive sodium bicarbonate PO TID or BID for a total of 90 days in the absence of disease progression or unacceptable toxicity.


Criteria:

Inclusion Criteria: - Any cancer patient enrolled in the study must have a written approval from their oncologist that a notation will be made in the patient's chart for their study participation - Subject without known cognitive impairment, central nervous system (CNS) metastasis, overt psychosis, major depression, or delirium as noted in the oncology medical record - Subject with a Karnofsky performance status scale of 80% or greater at time of consent - Subject has completed initial adjuvant therapy and is not currently receiving or waiting to receive chemotherapy during the next 120 days - Breast cancer subjects may be enrolled if they are receiving hormonal blockade therapy - Subject is not enrolled in any other clinical trials - Subject has a valid working phone number to be contacted with during the study - Subject must be willing to provide urine specimen for pH measurements during scheduled clinical visits - Subject must be willing to provide a 3 mL blood sample for metabolic panels during scheduled clinical visits - Subject does not have uncontrolled hypertension (systolic pressure > 140, diastolic pressure > 90) despite maximal anti-hypertensive therapy - Subject has healthy renal function: creatinine clearance: 88-128 mL/min; glomerular filtration rate (GFR): > 90 mL/min/1.7m^2 based on standard care results no older than 2 weeks; if no data exist, the subject will need to consent to a blood draw for a basic metabolic panel (which measures creatinine) for verification - Subject must be informed of the investigational nature of this study and must sign and written informed consent in accordance with institutional and federal guidelines - Subject is not pregnant or breastfeeding at time of consent; a pregnancy test will be conducted from urine sample on day of consent in premenopausal women - Subject agrees to use medically approved contraception (ie. condoms, oral contraceptive) if premenopausal
