Light Dosimetry for Photodynamic Therapy With Porfimer Sodium in Treating Participants With Malignant Mesothelioma or Non-Small Cell Lung Cancer With Pleural Disease Undergoing Surgery
This phase I trial studies the side effects and how well light dosimetry system works during photodynamic therapy with porfimer sodium in treating participants with malignant mesothelioma , non-small cell lung cancer or any other malignancy with pleural disease undergoing surgery. Light dosimetry measures the amount of laser light given during photodynamic therapy. Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to light. The activated drug may kill tumor cells. Using light dosimetry for intraoperative photodynamic therapy may help doctors estimate how much light is delivered during photodynamic therapy and decide if the treatment should be stopped or continued.

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- Histologically confirmed malignant mesothelioma , non-small cell lung cancer (NSCLC) or other malignancies with pleural disease without distant disease.
- Subjects must have an Eastern Cooperative Oncology Group (ECOG) scale of 0-2.
- Subjects of child-bearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry and for 6 months after surgery. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
- The subject must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent prior to receiving any study related procedure.
- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
- Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- White blood cell (WBC) \< 4,000.
- Platelet count \< 100,000.
- Total serum bilirubin \> 2 mg/dL.
- Serum creatinine \> 2 mg/dL.
- Alkaline phosphatase \> 3 times the upper normal limit.
- Serum glutamic oxaloacetic transaminase (SGOT) or serum glutamate pyruvate transaminase (SGPT) \> 3 times the upper normal limit.
- 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.
- Pregnant or nursing female subjects.
- Unwilling or unable to follow protocol requirements.
- Any condition which in the investigator?s opinion deems the subject an unsuitable candidate to receive porfimer sodium.
- Received an investigational agent within 30 days prior to enrollment.
Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
