Brief summary: The proposed investigation is a Phase 1 trial to determine the safety, tolerability, and maximum tolerated dose (MTD) of the combination of pioglitazone ( and carboplatin patients with advanced or metastatic solid malignancies.

Detailed description: * In Part I of the study, the maximum tolerated dose (MTD) will be determined. During part I, Cycle 1, days 1-28, pioglitazone will be administered once daily. On cycle 1, day 8, the first dose of carboplatin will be administered. On cycle 2, day 1, both carboplatin and pioglitazone will be administered. Cycles 2 and onward are 21-day cycles, with pioglitazone administered once daily and carboplatin administered once every 3 weeks. Part I of the study will end when the MTD has been determined in a minimum of 6 patients.
* In Part II of the trial, an MTD Expansion Cohort may be utilized to further characterize the safety profile and pharmacodynamics of the drug. Patients in the MTD Expansion Cohort will receive carboplatin alone on cycle 1, day 1. Over days 15-21 of the cycle pioglitazone will be administered alone. On cycle 2, day 1, both carboplatin and pioglitazone will be administered.

Cycle 2 and onward are 21-day cycles, with pioglitazone administered once daily and carboplatin administered once every 3 weeks.

Eligibility criteria: Inclusion Criteria:

* Histologically confirmed malignancy that is not curable with standard approaches and where carboplatin is appropriate therapy.
* During Part I of the trial (MTD determining phase), measurable or evaluable disease is acceptable. For Part II of the trial (expanded cohort) only, participants must have measurable disease by RECIST criteria version 1.1.
* Participants enrolled in Part II of the trial (expanded cohort) must have disease that is amenable to biopsy with reasonable safety and also be willing to undergo at least two serial tumor biopsies for correlative biomarker investigation as defined in Section 8.2.2.
* Any number of prior therapies are permitted. Prior carboplatin is allowed. Patients who have documented allergy to carboplatin may receive carboplatin with desensitization.

  * Age ≥18 years old.
  * ECOG performance status ≤ 1 (Appendix A).
  * Participants must have normal organ and marrow function as defined below:

    * Absolute neutrophil count ≥1,500/L
    * Hematocrit ≥ 27
    * Platelets ≥100,000/L
    * Total bilirubin within normal institutional limits
    * AST (SGOT)/ALT (SGPT)≤ 2.5 X institutional upper limit of normal
    * Creatinine within normal institutional limits or creatinine clearance ≥ 60 mL/min/1.73 m2 for subjects with creatinine levels above institutional normal.
* Able to swallow oral medication.
* Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
* Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

Participants who exhibit any of the following conditions at screening will not be eligible for admission into the study.

* Subjects who have been treated with standard chemotherapy or molecularly targeted agents within the past 3 weeks prior to trial first drug administration.
* Subjects who were receiving experimental therapies must wait 3 weeks from their last dose prior to enrolling. Subjects treated with nitrosoureas or mitomycin C cannot be enrolled until 6 weeks has elapsed since their last treatment.
* Extensive prior radiotherapy on more than 25% of the bone marrow, or prior bone marrow/stem cell transplantation. Prior radiation for local disease management is allowed if last fraction was completed at least 4 weeks prior to trial entry.
* Subjects who have undergone a major surgical procedure within the 6 weeks prior to trial entry.
* History of untreated central nervous system (CNS) metastases. Subjects with a history of prior treated brain metastasis are eligible provided that 1 month following treatment they are stable by CT scan without evidence of cerebral edema, and have no requirements for corticosteroids.
* Diabetic patients who are currently requiring oral hypoglycemic agents or insulin therapy.
* Patients who are currently receiving rosiglitazone or pioglitazone, or who have received dosing with any other agent known to be a PPAR agonist within 3 months prior to study entry.
* Left ventricular ejection fraction ≤ 50% on ECHO or MUGA
* Uncontrolled concomitant illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
* Pregnant or nursing women.
* Known HIV positivity, active hepatitis C, or active hepatitis B.
* Patients with ≥ CTCAE Grade 2 peripheral neuropathy.
* Subjects with a known history of gastrointestinal disorder (such as partial esophageal, gastric, small or large bowel obstruction), surgery or malabsorption that could potentially impact the swallowing or the absorption of the study drug.
* Patients taking CYP2C8 inhibitors and inducers (rifampin, gemfibrozil, trimethoprim, montelukast, and quercetin) are excluded from the trial.
* Other significant disease that in the Investigator's opinion would exclude the subject from the trial.
