AI Technical Summary

Benefits of technology

This combination significantly reduces disease progression, maintains stable disease, and achieves improved overall response rates compared to standard treatments, with a diastereomeric purity of at least 98% ensuring enhanced clinical efficacy.

Problems solved by technology

This in turn leads to suppression of DNA synthesis in the cells, which may lead to cell death by apoptosis.

Clinical Study Design

[0106]A multicenter, randomized, parallel-group, Phase IIb / III study in approximately 440 patients with advanced colorectal cancer is conducted to compare the efficacy of treatment with 6R-MTHF versus LV in combination with 5-FU, oxaliplatin, and bevacizumab.

[0107]This is a randomized, multicenter, parallel-group, Phase IIb / III study to compare the efficacy of arfolitixorin versus LV in patients with advanced CRC treated by 5-FU, oxaliplatin, and bevacizumab.

[0108]Patients will be randomized in a 1:1 ratio to either the investigational arm (arfolitixorin) or the comparator arm (Leucovorin), following the completion of all screening assessments and after confirmation of their eligibility, using a stratified permuted block randomization. Randomization will be stratified for the following baseline factors:[0109]Geographic region (Europe / North America)[0110]Primary tumor location (left colon / right colon / rectal cancer)[0111]Previous adjuvant CRC treatment

Treatment of Patient Diagnosed with Colorectal Cancer

[0188]An 81-year old female (71 kg; 155 cm) was diagnosed with stage IV metastatic colorectal cancer by PET / CT scan. Colorectal adenocarcinoma was verified by biopsy obtained by sigmoidectomy. Three solid tumors (baseline (prior to treatment) CT measurements: 25, 13 and 12 mm) were identified in the abdomen. The patient had previously been treated for colorectal cancer with eloxatin, which had been discontinued prior to the treatment disclosed here.

[0189]The patient received treatment comprising the administration of bevacizumab, oxaliplatin, 5-FU and 6R-MTHF as a second-line therapy. Bevacizumab was administered at a dose of 5 mg / kg by intravenous infusion over 30 to 90 minutes. Following administration of bevacizumab, oxaliplatin was administered at a dose of 85 mg / m2 by intravenous infusion between 15 and 120 minutes. Following oxaliplatin administration, 5-fluorouracil (5-FU) at a dose of 400 mg / m2 was administered by intraven...

Treatment of Patient Diagnosed with Colorectal Cancer

[0191]A 48-year old female (67 kg; 160 cm) was diagnosed with stage IV metastatic colorectal cancer by surgery. Colorectal adenocarcinoma was verified by biopsy obtained by masectomy. Two solid tumors (baseline (prior to treatment) CT measurements: 10 and 16 mm) were identified in the liver and lung. The patient had previously been treated for colorectal cancer with bevacizumab, which had been discontinued prior to the treatment disclosed here.

[0192]The patient received treatment comprising the administration of bevacizumab, oxaliplatin, 5-FU and 6R-MTHF as a second-line therapy. Bevacizumab was administered at a dose of 5 mg / kg by intravenous infusion over 30 to 90 minutes. Following administration of bevacizumab, oxaliplatin was administered at a dose of 85 mg / m2 by intravenous infusion between 15 and 120 minutes. Following oxaliplatin administration, 5-fluorouracil (5-FU) at a dose of 400 mg / m2 was administered by intravenous b...

Abstract

The present invention provides methods for treating patients diagnosed with colorectal cancer and metastatic colorectal cancers in a chemotherapeutic regimen comprising the administration of [6R]-5,10-methylene tetrahydrofolate (6R-MTHF), 5-fluorouracil (5-FU), bevacizumab, and oxaliplatin. The methods reduce disease progression and provide improved overall response rates compared to standard treatments with other folates such as folinic acid.
