Who may be able to join
- ELIGIBILITY CRITERIA (STEP 1): Patients must have histologically documented dedifferentiated liposarcoma (DDLPS). Patients with mixed well-differentiated/dedifferentiated liposarcoma (WD/DD LPS) tumors are eligible provided there is a histologically confirmed DDLPS component at some point during the treatment course
- Disease must be metastatic or locally advanced and surgically unresectable, in the opinion of the treating investigator
- Note: Intact retinoblastoma protein (RB) can be assumed in DDLPS. In a query of project Genomics Evidence Neoplasia Information Exchange (GENIE) (American Association for Cancer Research [AACR]), including 286 DDLPS tumors, the rate of RB1 mutation in DDLPS was 1.37%. Therefore, molecular testing to determine intact Rb is not required
- ELIGIBILITY CRITERIA (STEP 1): Patients must have at least one lesion that is measurable per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria to be eligible for this study. Previously radiated lesions should not be used as target lesions unless there is documented evidence of disease progression of that lesion after radiation
- ELIGIBILITY CRITERIA (STEP 1): Patients may have received any number of prior systemic treatment lines for DDLPS, including none
- ELIGIBILITY CRITERIA (STEP 1): Patients may not have received prior treatment with CDK4/6 inhibitors (including, but not limited to: palbociclib, ribociclib or abemaciclib) or anti-PD-1/anti-PD-L1 antibodies

About this study
Official title: Official Title A Randomized Phase 2 Trial With a Safety Lead-In to Evaluate Palbociclib Versus Palbociclib and Cemiplimab for the Treatment of Advanced Dedifferentiated Liposarcoma
This phase II trial compares the effect of treatment with palbociclib alone to treatment with palbociclib plus cemiplimab for treating patients with dedifferentiated liposarcoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Palbociclib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Cemiplimab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. The combination of these two drugs may be more effective in shrinking or stabilizing advanced dedifferentiated liposarcoma compared to palbociclib alone.
Read the detailed description
PRIMARY OBJECTIVES:
- To perform a safety lead-in among 6 patients to confirm that the combination of palbociclib and cemiplimab is safe and tolerable.
II. To evaluate whether palbociclib in combination with cemiplimab (Arm 2) demonstrates a superior progression-free survival (PFS) compared to palbociclib monotherapy (Arm 1) for patients with advanced dedifferentiated liposarcoma (DDLPS).
SECONDARY OBJECTIVES:
- To evaluate the toxicity profile in and across each treatment arm as determined by both Common Terminology Criteria for Adverse Events (CTCAE) and Patient Reported Outcomes (PRO)-CTCAE criteria.
II. To evaluate and compare the objective response rate (ORR) and duration of response (DOR) in and across each treatment arm.
III. To evaluate and compare the overall survival (OS) in and across each treatment arm.
IV. To evaluate and compare progression-free rate at 12 weeks (PFR12) in and across each treatment arm.
EXPLORATORY OBJECTIVES:
- To collect genomic sequencing data previously collected as standard of care, including data on CDK4 copy number (as determined by fluorescence in situ hybridization [FISH] or other molecular testing).
II. To conduct multiplex immunohistochemistry using archival tumor tissue (where available) to define densities of infiltrating immune cell subsets and tumor and immune cell major histocompatibility complex (MHC) and PD-L1 expression.
III. To perform an exploratory analysis to evaluate for any relationship between CDK4 copy number and (a) the tumor immune microenvironment as defined by multiplex immunohistochemistry and (b) clinical outcomes from study treatment.
IV. To explore efficacy and toxicity endpoints, including PFS and ORR, for patients who progress on palbociclib monotherapy and crossover to the palbociclib plus cemiplimab combination.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive palbociclib orally (PO) on study. Patients will be allowed to cross over to Arm II following documentation of disease progression. Patients undergo magnetic resonance imaging (MRI) or computed tomography (CT) scans throughout the trial. Patients may also undergo blood sample collection on study.
ARM II: Patients receive palbociclib PO and cemiplimab intravenously (IV) on study. Patients undergo MRI or CT scans throughout the trial. Patients may also undergo blood sample collection on study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival (PFS)
Efficacy analyses will be based on intention to treat principles. PFS will be compared between the two treatment arms using Kaplan-Meier methods. The hazard ratio, median PFS, and estimated PFS rates at 12, 24, 36, and 48 months will be estimated along with corresponding 95% confidence intervals. A log-rank test will be used to compare the PFS distributions between the two treatment arms in this cohort. Cox proportional hazards models will also be used to assess the impact of treatment arm on PFS when stratifying on the stratification factors.
Measured: The time from randomization to the first documentation of disease progression or death, assessed up to 48 months.
Secondary outcomes (4)
Incidence of adverse events
Patients will be evaluated for adverse events using the National Cancer Institute Common Toxicity Criteria for Adverse Events version 5.0. Summary statistics (e.g., mean, median, standard deviation) and frequency tables will be used to describe the distributions of adverse events. Rates of adverse events occurring in the treatment arm will be compared to the control arm with chi-squared tests (or suitable alternative) used for comparisons where applicable. Tolerability will also be evaluated, summarizing rates of dose delays or modifications, reasons patients end treatment, and time to end of active treatment.
Measured: Up to 2 years
Duration of response (DoR)
Defined for all evaluable patients who have achieved an objective response as the date at which the patient's earliest best objective status is first noted to be either a complete response or partial response to the earliest date progression is documented, or death if no prior evidence of disease progression. The distribution of DoR will be estimated using the method of Kaplan-Meier.
Measured: up to 2 years
Overall survival (OS)
Defined as the time from randomization to death due to any cause. Patients who are alive will be censored at last follow-up for OS. The distribution of survival time will be estimated using the method of Kaplan-Meier. OS will be compared between treatment arms using the log-rank test. OS medians, survival rates and hazard ratio will be estimated along with 95% confidence intervals.
Measured: up to 2 years
Progression free rate at 12 weeks (PFR12)
Defined as the proportion of evaluable patients who are alive and without evidence of disease progression 12 weeks after initiation of study therapy. The final PFR12 point estimate and corresponding 95% confidence interval calculated using Clopper-Pearson method.
Measured: At 12 weeks
