Application Number:	15/865,847
Patent Claims:	1. A method of treating a human diagnosed with a solid tumor, which method comprises: a) on Day 1, administering an IV bolus containing 10-1000 mg/m.sup.2 5-fluorouracil (5-FU) or a fluorinated pyrimidine base, followed, either simultaneously or after a period of 10 min-4 hours, by b) administering two or more IV boluses, interspaced by a period of 10-60 minutes, each containing 5-1000 mg/m.sup.2 [6R]-5,10-methylenetetrahydrofolate (6R-MTHF) on Day 1, followed by c) administering a continuous infusion of 5-FU or a fluorinated pyrimidine base over a period of 46 hours, or until the end of Day 2, followed by d) optionally administering one IV bolus containing 5-1000 mg/m.sup.2 6R-MTHF before the end of Day 1, followed by e) on Day 2, optionally administering one or more IV boluses each containing 5-1000 mg/m.sup.2 6R-MTHF, wherein step (b) is optionally repeated up to 4 times on Day 1 with an interval of 10 min-4 hours between each repetition, and wherein step (e) is optionally repeated up to 4 times on Day 2 with an interval of between 10 min-60 min between each bolus being administered, and wherein all steps (a)-(e) are optionally repeated every 2 weeks for up to eight (8) cycles. 2. The method according to claim 1, wherein the solid tumor is a cancer form selected from colon cancer, stomach cancer, breast cancer, bowel cancer, gallbladder cancer, lung cancer (specifically adenocarcinoma), colorectal cancer (CRC) including metastatic CRC, head and neck cancer, liver cancer, osteosarcoma and pancreatic cancer. 3. The method according to claim 1, wherein the two or more IV boluses of step (b) administered on Day 1 each contains from 20-250 mg/m.sup.2 6R-MTHF, such as from 30-240mg/m.sup.2, such as from 30-120 mg/m.sup.2 or such as about 30 mg/m.sup.2 or such as about 60 mg/m.sup.2 or such as about 120 mg/m.sup.2 6R-MTHF. 4. The method according to claim 1, wherein the solid tumor is a CRC including metastatic CRC. 5. The method according to claim 1, wherein step (a) is preceded by administering one or more anticancer drugs on Day 1 as an IV bolus or as an infusion over a period of 1-4 hours. 6. The method according to claim 5, wherein the anticancer drug is selected from oxaliplatin, irinotecan and bevacizumab. 7. The method according to claim 6, wherein the one or more anticancer drugs administered on Day 1 is oxaliplatin. 8. The method according to claim 5, wherein the one or more anticancer drugs administered on Day 1 is oxaliplatin in combination with bevacizumab. 9. The method according to claim 1, wherein at least two boluses of 6R-MTHF are administered on Day 2 under step (e). 10. The method according to claim 8, wherein up to four boluses of 6R-MTHF are administered with an interval of 20-30 min between each bolus. 11. The method according to claim 9, wherein up to four boluses of 6R-MTHF are administered with an interval of 20-30 min between each bolus. 12. The method according to claim 1, wherein the 6R-MTHF is a lyophilisate or a salt. 13. The method according to claim 1, wherein the 6R MTHF has a diastereomeric purity of greater than 98% diastereomeric excess. 14. The method according to claim 1, comprising performing and repeating steps (a) to (e) over a total treatment period of at least 8 weeks. 15. The method according to claim 14, comprising performing and repeating steps (a) to (e) over a total treatment period of at least 16 weeks. 16. The method according to claim 1 whereby said method retards progression of said solid tumors. 17. The method according to claim 14 whereby said method retards progression of said solid tumors. 18. The method according to claim 15 whereby said method retards progression of said solid tumors. 19. The method according to claim 1 whereby no statistically significant progression of said solid tumors is observed. 20. The method according to claim 14 whereby no statistically significant progression of said solid tumors is observed. 21. The method according to claim 15 whereby no statistically significant progression of said solid tumors is observed. 22. The method according to claim 1, wherein the fluorinated pyrimidine base is selected from the group consisting of 2'-deoxy-5-fluorouridine and 5'-deoxy-5-fluorouridine. 23. The method according to claim 1, wherein steps (a) and (c) comprise administering 5-FU.
