Testing the Addition of Cemiplimab to Palbociclib for the Treatment of Advanced Dedifferentiated Liposarcoma
I. 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:
I. 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 8 weeks (PFR8) in and across each treatment arm.
EXPLORATORY OBJECTIVES:
I. 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.

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. | The time from randomization to the first documentation of disease progression or death, assessed up to 48 months. |

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. | 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. | 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. | up to 2 years |
Progression free rate at 8 weeks (PFR8) | Defined as the proportion of evaluable patients who are alive and without evidence of disease progression 8 weeks after initiation of study therapy. The final PFR8 point estimate and corresponding 95% confidence interval calculated using Clopper-Pearson method. | At 8 weeks |
