Abstract

Disclosed herein are formulations and methods of administering formulations to starve cells of nutrients, such as amino acids. The formulations can be substantially devoid of one or more non-essential amino acids. A formulation disclosed herein can be given to a subject to treat a disease, for example, cancer. Removing a particular amino acid or a combination of amino acids from the diet of a subject can lead to improved treatment of various diseases, including cancer. Reduction of amino acid levels in a subject reduces the production of proteins, metabolites, lipids, or nucleic acid that can promote cancer growth and metastasis.

Claims (19)

1. A composition for treating a patient with cancer comprising in unit dosage form:

a) a non-essential amino acid comprising glutamate or a salt thereof in an amount from about 4% to about 8% (w/w), wherein the non-essential amino acid or the salt thereof is not part of a polypeptide;

b) a first essential amino acid comprising histidine or a salt thereof in an amount from about 3% to about 7% (w/w) and a second essential amino acid comprising isoleucine or a salt thereof in an amount from about 2% to about 6% (w/w), wherein the first essential amino acid or the salt thereof and the second essential amino acid or the salt thereof are not part of a polypeptide; and

c) a pharmaceutically acceptable excipient,

wherein the composition is devoid of two non-essential amino acids that are serine and salts thereof and glycine and salts thereof.

2. The composition of claim 1 , further comprising a third essential amino acid or a salt thereof, wherein the third essential amino acid or the salt thereof is present in the composition in a different amount from the first essential amino acid or the salt thereof and the second essential amino acid or the salt thereof.

3. The composition of claim 1 , wherein the composition is further devoid of proline and salts thereof.

4. The composition of claim 1 , wherein the composition is further devoid of cysteine and salts thereof.

5. The composition of claim 1 , wherein the unit dosage form has a weight of about 12 grams.

6. The composition of claim 1 , wherein the composition is in a powder form.

7. The composition of claim 1 , wherein the composition further comprises from about 2% to about 5% (w/w) of a K + source.

8. The composition of claim 7 , wherein the K + source comprises potassium citrate, potassium phosphate, potassium chloride, potassium sulfate, potassium gluconate, potassium bicarbonate, potassium aspartate, potassium acetate, potassium orotate, potassium bromate, potassium benzoate, potassium hydroxide, potassium iodide, or a hydrate thereof.

9. The composition of claim 1 , wherein the composition further comprises from about 1% to about 4% (w/w) of a Mg 2+ source.

10. The composition of claim 9 , wherein the Mg 2+ source comprises magnesium citrate, magnesium fumarate, magnesium acetate, magnesium aspartate, magnesium threonate, magnesium glycinate, magnesium chloride, magnesium sulfate, magnesium oxide, magnesium malate, magnesium orotate, magnesium gluconate, magnesium stearate, magnesium carbonate, or a hydrate thereof.

11. The composition of claim 1 , wherein the composition further comprises taurine, a hydrate thereof, or a salt thereof from about 0.05% to about 2% (w/w).

12. The composition of claim 1 , wherein the composition is further devoid of glutamine and salts thereof.

13. The composition of claim 1 , wherein the composition is further devoid of glutamine and salts thereof, and cysteine and salts thereof.

14. The composition of claim 1 , wherein the composition further comprises a flavorant.

15. The composition of claim 1 , wherein the composition further comprises a sweetener.
