Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Phase I (Tosedostat + Capecitabine) | * The phase I study will be conducted in the standard 6-patient-per-cohort dose de-escalation fashion.~* Tosedostat by mouth daily Days 1-21 of each 21-day cycle. Dose Level 0 (starting dose) = 120 mg PO daily and Dose Level -1 = 60 mg PO daily. All 6 patients in the Phase 1 received 120 mg starting dose of tosedostat.~* Capecitabine 1000 mg/m\^2 by mouth BID Days 1-14 of each 21-day cycle~* Fresh tissue biopsy: Patients who have a partial response at the end of cycle 2 will be required to undergo biopsy if deemed safe for the patient and tissue is feasible to obtain. | 6 | 6 | OG000 |
| Group 2 | Phase II (Tosedostat + Capecitabine) | * Tosedostat (dose determined by Phase I portion of study) by mouth daily Days 1-21 of each 21-day cycle~* Capecitabine by mouth BID Days 1-14 of each 21-day cycle~* Fresh tissue biopsy: Patients who have a partial response at the end of cycle 2 will be required to undergo biopsy if deemed safe for the patient and tissue is feasible to obtain. | 10 | 10 | OG001 |

- Title
- Number of Participants With a CA19-9 Response
- Description
* CA19-9 is a tumor marker that is used in the management of pancreatic cancer. Rising CA19-9 levels may mean the tumor is growing and decreasing CA19-9 levels may mean the tumor is shrinking or the amount of cancer in the body is decreasing~* A CA19-9 response means that the tumor marker has decreased over baseline (before treatment started) levels
