Brief Summary

This research study is designed to study the combination of two drugs, palbociclib and ganitumab, as a potential treatment for Ewing sarcoma.

The names of the study drugs involved in this study are:

• Palbociclib
• Ganitumab

Detailed Description

This research study involves participants taking a medicine that inhibits proteins in cancer cells called CDK4 and CDK6 (palbociclib) in combination with a medicine that inhibits a protein called IGF-1R (ganitumab). This study is designed to see if these drugs are safe when given together and whether they are effective in treating Ewing sarcoma.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug or drug combination to learn whether the drug(s) works in treating a specific disease. "Investigational" means that the drug or combination is being studied.

The U.S. Food and Drug Administration (FDA) has not approved ganitumab as a treatment for any disease.

The U.S. Food and Drug Administration (FDA) has not approved palbociclib for this specific disease but it has been approved for another cancer.

This research study is:

• Testing whether palbociclib and ganitumab are safe when given together and effective in treating Ewing sarcoma.
• Testing markers in the blood and in tumor tissue to see if there are certain features of the tumor that may indicate this combination of drugs is effective or not effective

Conditions

Ewing Sarcoma; Ewing's Sarcoma Recurrent

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

PALBOCICLIB and GANITUMAB

Participants receive up to 12 cycles of therapy (cycle duration=28 days).

• Palbociclib: Oral, 100mg, daily on days 1-21
• Ganitumab: Intravenous, 18mg/kg, days 1, 15

Per protocol, participants were monitored for dose-limiting toxicity over cycle one according to an interim safety analysis. The safety monitoring rule was triggered after 3 patients had enrolled, prompting an amendment according to Contingency Plan A which was a reduction of the palbociclib dose from 125mg (days 1-21).

Group Type: EXPERIMENTAL

• Patients must have fully recovered (Common Terminology Criteria for Adverse Events [CTCAE] version 5 Grade ≤1) from the acute toxic effects of all prior anti-cancer therapy except organ function as noted in Section 3.1.6. Patients must meet the following minimum washout periods prior to enrollment:
• Myelosuppressive chemotherapy: At least 14 days after the last dose of myelosuppressive chemotherapy (42 days for nitrosourea or mitomycin C).

• At least 42 days must have elapsed if other substantial bone marrow radiation;
• Small molecule biologic therapy: At least 7 days following the last dose of a biologic agent. For agents with known adverse events occurring beyond 7 days, this duration must be extended beyond the time in which adverse events are known to occur. If extended duration is required, this should be discussed and approved by the study chair.
• Monoclonal antibody: At least 21 days must have elapsed after the last dose of antibody.
• Myeloid growth factors: At least 14 days following the last dose of long-acting growth factor (e.g. Neulasta®) or 7 days following short-acting growth factor.

• Stem Cell Infusion or Cellular Therapies: The patient must have no evidence of graft versus host disease and at least 42 days must have elapsed after transplant, stem cell infusion, or cellular therapy.
• Major Surgery: At least 2 weeks from prior major surgical procedure. Note: Biopsy and central line placement/removal are not considered major surgery.
• CDK4/6 and IGF-1R inhibitors: The participant must not have received a prior CDK4/6 inhibitor. Prior therapy with IGF-1R inhibitor is allowed if the patient did not relapse while on IGF-1R therapy. Patients must not have received prior therapy with a combination of CDK4/6 inhibitor and IGF-1R inhibitor.
