Abstract

Provided herein are pharmaceutically acceptable sodium thiosulfate and pharmaceutical compositions thereof. Also provided herein are methods for determining the total non-purgeable organic carbon in a sodium thiosulfate-containing sample. Further provided herein are methods for producing pharmaceutically acceptable sodium thiosulfate. Still further provided herein are methods of treatment comprising the administration of pharmaceutically acceptable sodium thiosulfate.

Claims (20)

1. A method for treating platinum-induced ototoxicity, comprising administering to a subject having platinum-induced ototoxicity, a platinum coordination complex in combination with pharmaceutical grade sodium thiosulfate pentahydrate, wherein the pharmaceutical grade sodium thiosulfate pentahydrate contains no greater than about 8 ppm of non-purgeable organic carbon, contains no greater than about 0.05 ppm of mercury, contains no greater than about 2 ppm of aluminum, contains no greater than about 0.003% by weight of selenium, contains no less than about 98% by weight and no greater than about 102% by weight of sodium thiosulfate on an anhydrous basis measured by ion chromatography, has a water content between 32% and 37% by weight, has a heavy metal content of no greater than about 10 ppm, contains no greater than about 200 ppm of chloride, contains no greater than about 0.001% by weight of sulfide, contains no greater than about 0.002% by weight of iron, contains no greater than about 0.01% by weight of calcium, contains no greater than about 0.005% by weight of potassium, contains no greater than about 0.1% of sulfite, contains no greater than about 0.5% of sulfate, contains no greater than about 3 ppm of arsenic, contains no greater than about 0.001% by weight of lead, has total aerobic count of microbial load of no greater than about 100 CFU/g, has total yeast and mold count of no greater than about 20 CFU/g, contains no greater than about 0.02 EU/mg of bacterial endotoxins, contains no greater than about 0.002% by weight of nitrogen compounds, contains no greater than about 0.005% by weight of insoluble matter, contains no greater than 0.01% by weight of residual anti-caking agent, and contains no greater than ICH Q3C (R3) limits of organic volatile impurities.

2. The method of claim 1 , wherein the platinum coordination complex is cisplatin, satraplatin, or carboplatin.

3. The method of claim 2 , wherein the platinum coordination complex is cisplatin.

4. The method of claim 2 , wherein the platinum coordination complex is satraplatin.

5. The method of claim 2 , wherein the platinum coordination complex is carboplatin.

6. The method of claim 1 , wherein the administration is oral.

7. The method of claim 1 , wherein the administration is topical.

8. The method of claim 1 , wherein the administration is intradermal, dermal or transdermal.

9. The method of claim 1 , wherein the administration is intravenous or subcutaneous.

10. The method of claim 1 , wherein the administration is rectal.

11. A method for treating platinum-induced nephrotoxicity, comprising administering to a subject having platinum-induced nephrotoxicity, a platinum coordination complex in combination with pharmaceutical grade sodium thiosulfate pentahydrate, wherein the pharmaceutical grade sodium thiosulfate pentahydrate contains no greater than about 8 ppm of non-purgeable organic carbon, contains no greater than about 0.05 ppm of mercury, contains no greater than about 2 ppm of aluminum, contains no greater than about 0.003% by weight of selenium, contains no less than about 98% by weight and no greater than about 102% by weight of sodium thiosulfate on an anhydrous basis measured by ion chromatography, has a water content between 32% and 37% by weight, has a heavy metal content of no greater than about 10 ppm, contains no greater than about 200 ppm of chloride, contains no greater than about 0.001% by weight of sulfide, contains no greater than about 0.002% by weight of iron, contains no greater than about 0.01% by weight of calcium, contains no greater than about 0.005% by weight of potassium, contains no greater than about 0.1% of sulfite, contains no greater than about 0.5% of sulfate, contains no greater than about 3 ppm of arsenic, contains no greater than about 0.001% by weight of lead, has total aerobic count of microbial load of no greater than about 100 CFU/g, has total yeast and mold count of no greater than about 20 CFU/g, contains no greater than about 0.02 EU/mg of bacterial endotoxins, contains no greater than about 0.002% by weight of nitrogen compounds, contains no greater than about 0.005% by weight of insoluble matter, contains no greater than 0.01% by weight of residual anti-caking agent, and contains no greater than ICH Q3C (R3) limits of organic volatile impurities.

12. The method of claim 11 , wherein the platinum coordination complex is cisplatin, satraplatin, or carboplatin.

13. The method of claim 12 , wherein the platinum coordination complex is cisplatin.

14. The method of claim 12 , wherein the platinum coordination complex is satraplatin.

15. The method of claim 12 , wherein the platinum coordination complex is carboplatin.

16. The method of claim 11 , wherein the administration is oral.

17. The method of claim 11 , wherein the administration is topical.

18. The method of claim 11 , wherein the administration is intradermal, dermal or transdermal.

19. The method of claim 11 , wherein the administration is intravenous or subcutaneous.

20. The method of claim 11 , wherein the administration is rectal.
