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 | Arm A (Pazopanib Hydrochloride, Ascorbic Acid) | Patients receive pazopanib hydrochloride PO QD on days 1-28 and ascorbic acid IV three times per week. Treatment repeats every 28 days for up to 10 cycles in the absence of disease progression or unacceptable toxicity. | 0 | 1 | OG000 |
| Group 2 | Arm B (Pazopanib Hydrochloride) | Patients receive pazopanib hydrochloride PO QD on days 1-28. Treatment repeats every 28 days for up to 10 cycles in the absence of disease progression or unacceptable toxicity. | 1 | 3 | OG001 |

- Title
- Overall Response Rate
- Description
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by CT scan, PET/CT, or MRI: Complete Response (CR), Disappearance of all target lesions and all target lymph nodes must have reduction in short axis to \<1.0 cm; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions plus the sum of the short axis of all the target lymph nodes at current evaluation; Overall Response (OR) = CR + PR. Will be compared using a Chi-Square test.
