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 | Dasatinib 100 mg Once Daily (QD) | Participants were administered an oral dose of 100 mg dasatinib tablet QD. Participants continued to receive the study drug as long as tolerated or until progressive disease (PD), defined as appearance of new lesion/s, or \>=20% increase in the sum of the longest diameter (LD) of target lesions, relative to the smallest sum LD recorded since treatment start, or unequivocal progression of existing non-target lesions. | 30 | 48 | OG000 |
| Group 2 | Dasatinib 100 mg or 70 mg Twice Daily (BID) | Participants were administered an oral dose of 100 mg dasatinib tablet BID for a total daily dose (TDD) of 200 mg which was later decreased to 70 mg BID for a TDD of 140 mg. Of the 47 treated participants in the BID group, 25 received 100 mg and 22 received 70 mg of dasatinib as their starting doses. Participants continued to receive the study drug as long as tolerated or until progressive disease (PD), defined as appearance of new lesion/s, or \>=20% increase in the sum of the longest diameter (LD) of target lesions, relative to the smallest sum LD recorded since treatment start, or unequivocal progression of existing non-target lesions. | 34 | 47 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants With Disease Progression
- Description
Disease progression: progression of target lesions or unequivocal progression of non-measurable lesions/disease as evaluated by computed tomography (CT) scan or magnetic resonance imaging (MRI), not as evaluated by bone scan (non-measurable lesions included visceral and bone lesions), loss of PSA response (only for participants who achieved a PSA response) or Investigator-defined clinical progression based on physical examination, history, symptoms, and ECOG-PS. For participants who did not progress or die, date of last PSA measurement or tumor assessment was used, whichever occurred first.
- Time frame
- Prior to treatment with the study drug, Week 12 and every 12 weeks thereafter and at the end of the treatment.
- Population
- All treated participants.
