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 | Larotrectinib | Pediatric patients (up to 21 years old) with Infantile fibrosarcoma (IFS) harboring an NTRK gene fusion who have been enrolled in the SCOUT study (Bayer Study ID: 20290; NCT02637687) and treated with larotrectinib. | 0 | 51 | OG000 |
| Group 2 | External Controls | External historical control patients treated with at least one chemotherapy-based regimen, pooled from the Institut Curie (CURIE) database (N=18) and the Cooperative Weichteilsarkom Studiengruppe (CWS) database (N=24). | 1 | 42 | OG001 |
