IPI-504 in NSCLC Patients With ALK Translocations

IPI-504 blocks a protein that is in cancer cells and is also in normal cells. This protein is called Heat Shock Protein-90 (Hsp90). Hsp90 helps protect certain other proteins from being destroyed by cells. These proteins can mutate to give off signals that allow cancer cells to keep growing. By blocking the function of Hsp90, we hope that the cancer cell will block the mutated protein and cause the cancer cells to die. This drug have been used in other research studies and in the laboratory and information from those other research studies suggests that thsi drug may help to treat lung cancer with ALK mutations. In this research study, we are looking to see what effects IPI-504 has in patients with lung cancer who have an ALK mutation.

* Participants will receive the study drug (IPI-504) twice weekly for two weeks followed by 10 days without study treatment. This 3-week period is called a cycle. Participants will receive a total of 4 doses per cycle. On the days the participant receives study drug, they will come to the clinic and be given the IPI-504 by being. Participants will continue to receive study drug for additional cycles as long as they are benefiting from it and do not experience any severe side effects.
* Participants will have CT scans to assess the size and location of their tumor. They may also have a PET scan or a combination of PET/CT scans. Imaging will be done at the beginning of treatment and every five to six weeks while on study to assess how the tumor is responding to IPI-504.
* The following tests and procedures will be done on the prior to the first dose of IPI-504: physical examination, vital signs, routine blood tests, EKGs, serum or urine pregnancy test (for women of child-bearing potential).
* After the first dose of IPI-504, the following tests and procedures will be done: EKGs, vital signs (pulse only).
* For all other visit days throughout the study, the following exams, tests and procedures will be done: physical examination, vital signs, blood tests, tumor imaging assessments, MRI of the brain (if applicable), review of medications and answer questions about any side effects or changes in health.
* After the final dose of study drug the following tests and procedures will be done within 30 days: physical examination, ECOG Performance status, blood tests, review of medications and answer questions about any side effects of changes in health.

Eligibility Criteria:
Inclusion Criteria:

* Patients must have pathologically confirmed diagnosis of Stage IIIb (with malignant pleural or pericardial effusion), Stage IV, or recurrent NSCLC.
* Patients must have demonstrated ALK mutation
* There is no requirement for a minimum or maximum number of prior therapies, however, patients must have refused, be intolerant to or already received at least on standard systemic therapy for lung cancer
* Measureable disease by RECIST criteria. If a patient has received radiation therapy then measurable disease must be outside the radiation field.
* 18 years of age or older
* Life expectancy of at least 3 months
* ECOG performance status of 0-2
* Baseline studies for determining eligibility, except for ALK mutation status, must be completed within 30 days of first study dose.
* CT scan must be completed within 28 days prior to first study dose
* Women of child-bearing potential (WBCP) defined as a sexually mature woman who has not undergone a hysterectomy or who has not been naturally post-menopausal for at least 24 consecutive months must have a negative serum or urine pregnancy test within 2 weeks of first study dose
* All WCBP and all sexually active male patients must agree to use adequate methods of birth control throughout the study

Exclusion Criteria:

* Treatment for NSCLC with any approved or investigational product within 2 weeks of Cycle 1, Dose 1 for any small molecule therapy; within 4 weeks of Cycle 1, Dose 1 for any biologic or any conventional chemotherapy.
* Concurrent radiation therapy is not permitted
* Use of a medication or food that is clinically relevant CYP3A inhibitor or inducer within 2 weeks prior to Cycle 1, Dose 1
* Laboratory values as outlined in the protocol
* Baseline QT corrected using Fridericia's correction method (QTcf) \> 470ms. Patients with left bundle branch block are eligible regardless of QTcf, as long as serum troponin is normal or undetectable
* Presence of active infection or systemic use of antibiotics within 72 hours of treatment
* Significant co-morbid condition or disease which in the judgment of the investigator would place the patient at undue risk or interfere with the study
* Women who are pregnant or lactating
* Previous treatment with 17-AAG, DMAG, or other known Hsp90 inhibitor
* Sinus bradycardia secondary to intrinsic conduction system disease. Patients with sinus bradycardia secondary to pharmacologic treatment may enroll if withdrawal of the treatment results in normalization of the resting heart rate to within normal limits
* Active keratitis or keratoconjunctivitis
* Alkaline phosphatase \> 1.5 x ULN. Patients with bone metastases and an alkaline phosphatase level \> 1/5 x ULN and less than or equal to 3 x ULN are eligible if they meet the criteria outlined in the protocol
* Prothrombin time (PT) and partial thromboplastin time (PTT) \> 1.5 x ULN unless the patient is receiving warfarin. If the patient is receiving warfarin, the international normalized ratio must be within therapeutic range
* Patients with clinically active brain metastasis or an uncontrolled seizure disorder, ongoing spinal cord compression, or carcinomatous meningitis. Patients with clinically stable brain metastasis are eligible.
* Patients with prior hepatic resection or hepatic-directed therapy
