PalboSarc: Trial of Palbociclib in Second Line of Advanced Sarcomas With CDK4 Overexpression.
Study Details
Study Description
Brief Summary
Non-randomized, open, two-cohort, phase II, multicenter national clinical trial. 20 sites in Spain.
Cohort 1 includes soft-tissue sarcoma and osteosarcoma (21 patients), while Cohort 2 includes chordoma patients only (19 patients).
Palbociclib will be administered orally at a dose of 125 mg once a day for 21 consecutive days followed by 7 rest days to comprise a complete cycle of 28 days. Treatment will continue until disease progression, development of unacceptable toxicity, non-compliance, withdrawal of consent by the patient or investigator decision.
The main goal is to determine progression-free survival rate (PFSR) according to RECIST 1.1 at 6 months.

Outcome Measures
Primary Outcome Measures
- Progression free survival (PFS) rate [At 6 months]
Efficacy measured through the progression free survival (PFS) rate at 6 months, evaluated with RECIST 1.1 criteria.
Secondary Outcome Measures
- Overall response rate (ORR) [6 months]
Efficacy measured through the overall response rate (ORR) (complete response [CR] and partial response [PR]), evaluated with RECIST 1.1 criteria. The evaluation criteria will be based on the identification of target lesions in baseline and their follow-up until tumor progression.
- Efficacy measured through response according to Choi criteria measured through response according to Choi criteria: [6 months]
Efficacy measured through response according to Choi criteria. The evaluation criteria will be based on the identification of target lesions in baseline and their follow-up until tumor progression.
- Efficacy measured through median PFS [6 months]
Efficacy measured through median PFS.
- Efficacy measured through PFS rate at 3 months [3 months]
Efficacy measured through PFS rate at 3 months.
- Overall survival (OS) [2 years]
Overall survival (OS) measured from the date of treatment initiation with palbociclib until date of death, whichever the cause.
- Clinical Benefit Rate (CBR) [6 months]
Clinical Benefit Rate (CBR). Patients having shown complete response, partial response, or disease stabilization during 6 months or more, showing clinical improvement symptoms, will be considered as having experienced clinical benefit.
- Palbociclib safety profile [1 year]
Palbociclib safety profile, through the evaluation of adverse events (type, incidence, severity, timing of appearance, related causes) observed in physical explorations and laboratory tests. Toxicity will be assessed and tabulated using NCI-CTCAE 4.0 (first cohort; STS and osteosarcoma) and 5.0 (second cohort; chordomas).
