If random glucose ≤ 160 mg/dL (or ≤ 8.9 mmol/L), fasting value does not need to be obtained.~* Additional Agent-Specific Requirements~  * Patients must be able to swallow capsules.~ * For patients with CNS metastatic disease, any baseline neurologic deficits (including seizure) must be stable for at least one week prior to study enrollment.~* Ability to understand and/or the willingness of the patient (or parent or legally authorized representative, if minor) to provide informed consent, using an institutionally approved informed consent procedure.~Exclusion Criteria:~* Patients must not be receiving any of the following concomitant medications:~  -- Pharmacologic doses of systemic corticosteroids unless for CNS metastatic disease. For patients with CNS metastatic disease receiving corticosteroids, they should be on a stable or decreasing dose over the 7 days prior to registration Section 3.1.6.7 of protocol document. For all patients, receipt of systemic physiologic replacement steroids, topical and/or inhaled corticosteroids is acceptable.~* Patients receiving medications that are strong inhibitors or inducers of CYP3A4 within 7 days of enrollment (refer to Appendix B, Table 10 for prohibited medications)~* Patients receiving medications that cause significant QTc prolongation as outlined in Table 12 of Appendix B.~* Patients who have had tumor molecular testing with sequencing of the RB1 gene and were found to have RB1 mutation or loss will be excluded.~* Patients with a history of pneumonitis will be excluded.~* Pregnant participants will not be entered on this study given that the effects of palbociclib and ganitumab on the developing human fetus are unknown.~* Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with palbociclib and ganitumab, breastfeeding mothers are not eligible.~* Participants of child-bearing or child-fathering potential must agree to use adequate contraception (hormonal birth control; intrauterine device; double barrier method; or total abstinence) throughout their participation, including up until 30 days after last dose of palbociclib or ganitumab, whichever was administered last.~* History of allergic reactions attributed to compounds of similar chemical or biologic composition to palbociclib or ganitumab.~* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.~* Participants with a personal history of any of the following: syncope due to an intrinsic cardiac etiology (note that syncope due to vasovagal episodes or dehydration/orthostasis would NOT exclude a participant), pathologic ventricular arrhythmias (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest.~* Patients with known HIV, hepatitis B, and/or hepatitis C (testing not required as part of screening).~* Patients with a known history of type 1 or type 2 diabetes mellitus.~* Patients with gastrointestinal disease or disorder that could interfere with absorption of palbociclib, such as bowel obstruction or inflammatory bowel disease.~* Patients \< 40 kg will be excluded given use of palbociclib at non-weight / non-BSA based flat dosing.

- Maximum Age: 50 Years
- Healthy Volunteers: f

Study Arms:
- PALBOCICLIB and GANITUMAB (Type: EXPERIMENTAL): 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).

Based on this trial design, predict the completion outcome and termination type (if applicable).
