Brief summary: Background:

- PF-02341066 and PF-00299804 are drugs that specifically target certain proteins that may be more active in cancer cells than normal cells, in particular in non-small cell lung cancer. Both drugs seem to be able to stop the growth of or kill cancer cells. Researchers want to combine them to see if they are a safe and effective treatment for advanced non-small cell lung cancer.

Objectives:

- To test the safety and effectiveness of PF-02341066 and PF-00299804 for advanced non-small cell lung cancer.

Eligibility:

- Individuals at least 18 years of age with advanced non-small cell lung cancer that has not responded to standard treatments.

Design:

* Participants will be screened with a medical history and physical exam. They will also have blood and urine tests, and imaging studies. Heart and lung function tests and an eye exam may also be given.
* The first cycle of treatment will be 28 days. Every cycle after the first will be 21 days. Participants may have up to 17 cycles of treatment.
* Participants will take both study drugs as tablets. Twelve hours after the first dose, participants will take only the PF-02341066. This dose schedule will remain the same throughout the study.
* Participants will be monitored with frequent blood and urine tests and imaging studies. Tumor biopsies will be taken as needed. Those in the study will keep a diary to record any symptoms or side effects of taking the study drugs.
* After 17 cycles of treatment, or after stopping the study drugs early for any other reason, participants will have a final followup visit.

Detailed description: BACKGROUND:

* Approximately 85% of lung cancer is defined histologically as NSCLC and the majority of patients present with inoperable locally advanced (Stage IIIB) or metastatic (Stage IV) disease for which no curative treatment is available.
* Patients with disease progression on or after first-line treatment with platinum-based doublets may be candidates for second-line treatment.
* Recent evidence strongly implicates EGFR activating somatic mutations as a mechanism of tumorigenesis and a determinant of sensitivity to EGFR TKIs in NSCLC.
* Despite the dramatic initial response to gefitinib and erlotinib, about 50% of NSCLC tumors develop resistance due to secondary activating mutations in EGFR itself, including the EGFR T790M gatekeeper mutation, and more than 20% of acquired resistance is due to an increase in mesenchymal-epithelial transition factor (c-Met) signaling.
* There is evidence from a limited number of tumors from patients with acquired resistance to EGFR-TKIs that both T790M and cMET resistance mechanisms can occur in the same patient at different metastatic sites and even in different fractions of the same lesion.
* Tumors with acquired resistance to erlotinib and gefitinib might be vulnerable to a combination of PF-00299804 a second generation EGFR TKI which is also an inhibitor of T790M mutation, and PF-02341066 which is an inhibitor of c- Met/Hepatocyte Growth Factor Receptor (HGFR).

OBJECTIVES:

- To define the recommended Phase 2 dose (RP2D) of combined PF-02341066 plus

PF-00299804 in patients with advanced Non-Small Cell Lung Cancer (NSCLC).

* To assess the overall safety and tolerability, plasma pharmacokinetics (PK) and clinical activity of combined PF-02341066 plus PF-00299804.
* To analyze potential predictive and pharmacodynamic biomarkers in tumor and blood in patients with advanced NSCLC who have acquired resistance to erlotinib or gefitinib

ELIGIBILITY:

* Dose Escalation Phase: Adults with histologically documented diagnosis of NSCLC that is locally advanced or metastatic, after failure of either at least one chemotherapy regimen or treatment with erlotinib or gefitinib.
* Expansion Phase: Adults with histologically documented diagnosis of NSCLC that is locally advanced or metastatic, with acquired resistance to erlotinib or gefitinib, and must have one lesion amendable to biopsy.
* All pathology samples will be reviewed at the NCI.

DESIGN:

* Phase 1, multi-center, open-label, non-randomized trial of combined oral PF- 02341066 and oral PF-00299804 in patients with advanced NSCLC. Trial consists of two phases.
* Dose Escalation Phase: Patients will be treated with varying doses of combined PF- 02341066 plus PF-00299804. Tumor biopsy is not required.
* Expansion Phase: Two expansion cohorts will run concurrently following completion of the Dose Escalation Phase. Both cohorts will enroll patients with locally advanced or metastatic NSCLC with acquired resistance to erlotinib or gefitinib, which is defined as progression following an initial response (complete or partial) or stable disease for at least six months while on erlotinib or gefitinib.
* The dose escalation phase and the dose expansion phase can run concurrently insofar as the dose expansion phase can enroll before completion of the dose escalation phase provided that the dose used in the expansion phase has already been tested in the escalation phase and has been declared safe; i.e., for each specific safe dose the escalation phase is followed by the expansion phase.
* Tumor biopsy is mandatory for Expansion Phase entrance, however, all patients will be treated with study drugs irrespective of the biomarker identified which will be analyzed retrospectively. The mandatory biopsy in the Expansion Phase is necessary in order to identify acquired mutations that change over time.
* Expansion cohort 1 will continue to evaluate safety, tolerability and PK of the drug combination PF-02341066 plus PF-00299804.
* Expansion cohort 2 will enroll patients who are either untreated by prior PF- 00299804 or who have progressed on single agent PF-00299804 administered in an ongoing clinical trial. Patients who are previously untreated with PF-00299804 will be treated sequentially; i.e., first with single agent PF-00299804 until progression, then with the combination of PF-02341066 plus PF-00299804. Those who progressed with single agent PF-00299804 on another clinical trial will be treated with the combination PF-02341066 plus PF-00299804.

* Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
* Use of drugs or foods that are known potent CYP3A4 inhibitors within 7 days prior to the first dose of study medication, including but not limited to itraconazole, ketoconazole, miconazole, clarithromycin, erythromycin, indinavir, nefazodone, amprenavir, delavirdine, nelfinavir, ritonavir, saquinavir, diltiazem, verapamil and grapefruit juice.
* Use of drugs that are known potent CYP3A4 inducers within 12 days prior to the first dose of study medication, including but not limited to carbamazepine, phenobarbital, phenytoin, rifabutin, rifabutin, rifampin, tipranavir, ritonavir, and St. John s wort.
* Concurrent use of drugs that are CYP3A4 substrates with narrow therapeutic indices, including but not limited to pimozide, aripiprazole, triazolam, ergotamine and halofantrine.
* Concurrent use of drug that are highly dependent on CYP2D6 metabolism including S-metoprolol, propafenone, timolol, amitriptyline, clomipramine, desipramine, imipramine, paroxetine, haloperidol, risperidone, thioridazine, codeine, flecainide, mexilletine, tamoxifen, venlafaxine.

Dextromethorphan, a CYP2D6, substrate is allowed if medically indicated and no suitable alternative anti-tussive medication is available. However, the dose of dextromethorphan may need to be modified. In a clinical study in healthy volunteers who were extensive metabolizers (A7471039) PF-00299804 increased mean total exposure (AUC(last) and C(max)) of dextromethorphan 855% and 874%, respectively, following concomitant administration with PF-00299804 45 mg compared to exposure of administration of dextromethorphan alone. Extensive metabolizers comprise approximately 80% of the population, with ultra-, intermediate-, and poor-metabolizers accounting for the remaining portion of the general population. Therefore, if no alternative is available dextromethorphan dosing should be initiated at a lower dose (approx 25%) with close monitoring of patient clinical status. Dose increases or decreases of dextromethorphan may be considered based upon individual patient tolerability.

Lidocaine may be used systemically with clinical monitoring (including telemetry).

Opiates such as morphine, oxycodone, dihydrocodeine, hydrocodone, and tramadol can be used as substitutes to replace codeine. Use of these opiates should be monitored for altered analgesic effect during treatment as they may be partly metabolized by CYP2D6.
