  Purpose

Background:

Standard therapy for mesothelioma is a combination of the drugs pemetrexed and cisplatin. However, the benefits of this treatment are limited, and in most treated patients the disease continues to worsen.

SS1(dsFV)PE38 is a genetically engineered drug. It contains an antibody that binds to a certain protein on mesothelioma cells and a toxin (type of poison) made from a product of a bacterium called Pseudomonas aeruginosa. It is hoped that the antibody will attach to the cancer cells, allowing the toxin to enter and kill the cells.

Objectives:

To find out if SS1(dsFV)PE38, together with pemetrexed and cisplatin is safe and tolerable in patients with mesothelioma.

To determine the maximum tolerated dose of SS1(dsFV)PE38 (the highest dose that does not cause unacceptable side effects).

To see if SS1(dsFV)PE38 given with pemetrexed and cisplatin has any effect on patients tumors.

To learn how the body breaks down SS1(dsFV)PE38.

Eligibility:

Patients 18 years of age and older with epithelial pleural mesothelioma whose disease cannot be cured with surgery, and have not had prior treatment with chemotherapy.

Design:

Treatment with pemetrexed, cisplatin and SS1(dsFV)PE38 in two 21-day cycles as follows:

  • Day 1 - Intravenous (through a vein) infusions of pemetrexed and cisplatin.
  • Days 1 and 2 - Intravenous solution to prevent dehydration that might occur with SS1(dsFV)PE38.
  • Days 1, 3 and 5 Intravenous infusion of SS1(dsFV)PE38. Small groups (3 to 6) of patients are given SS1(dsFV)PE38 at a certain dose level. If the first group experiences no significant side effects, the next group a higher dose. This continues in succeeding groups until the maximum tolerated study dose (highest dose that patients can be given safely) is determined.

Continuing standard treatment with additional cycles of pemetrexed and cisplatin.

Evaluations during the treatment period:

  • Physical examination, including vital signs and body weight checks, and pregnancy test for women who can become pregnant.
  • Questions about medications and side effects.
  • Blood and urine tests.
  • Disease evaluation with CT, chest X-ray, and possibly PET scans, lung function tests, pulse oximetry, performance of daily activities and quality-of-life questionnaires.

Post-treatment evaluations:

  • Clinic visits at months 1, 3, 6, 12, 15, 18 and 21 for physical examination and disease assessment.
  • End-of-study visit for blood tests, vital signs and weight measurements, disease assessment, electrocardiogram, pregnancy test for women who can become pregnant

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria
  • INCLUSION CRITERIA:

Subjects must meet all of the following criteria to be eligible to participate in the study:

Subjects must have histologically confirmed epithelial or biphasic pleural mesothelioma not amenable to potentially curative surgical resection. However, patients with biphasic tumors that have a predominantly sarcomatoid component will be excluded.

Measurable disease

Subjects must be greater than or equal to 18 years old

Karnofsky Performance Status (KPS) of greater than or equal to 70

Life expectancy of greater than 3 months, as assessed by the principal investigator.

Adequate organ function with:Hepatic function: serum transaminases (either ALT or AST) or bilirubin, less than or equal to Grade 1, unless due to cancer or Gilbert s disease; less than or equal to Grade 2, if due to cancer

Renal function: serum creatinine clearance greater than or equal to 60mL/min as estimated by Cockroft-Gault formula.

Bone marrow function: ANC of at least 1,500/mm (3), Platelet count at least 100,000/mm (3)

Pulmonary Function: FEV (1) greater than or equal to 50 percent of predicted value (post-pleural drainage and bronchodilation if these are indicated)

Must be able to understand and sign informed consent

Female and male subjects agree to use an approved method of contraception during the study

EXCLUSION CRITERIA:

Subjects must not be pregnant or breast feeding

Prior radiotherapy (except palliative extra-thoracic localized radiotherapy) or biologic therapy for malignant pleural mesothelioma within 4 weeks

Prior systemic chemotherapy for malignant pleural mesothelioma

Documented and ongoing central nervous system involvement with their malignant disease (history of CNS involvement is not an exclusion criterion but the CNS metastases should have been adequately treated (radiation or surgical resection) and subjects are free from symptoms for 3 months off steroids).

Clinically significant heart disease (New York Heart Association Class III or IV)

Active bacterial or fungal infection.

Baseline coagulopathy greater than or equal to Grade 3 unless due to anticoagulant therapy

Surgery or pleurodesis within 2 weeks

HIV positive serology (due to increased risk of severe infection and unknown interaction of SS1(dsFv)PE38 with antiretroviral drugs)

Hepatitis B surface antigen positivity

Subjects with other (non-mesothelioma) cancers who meet eligibility criteria and have had less than 5 years of disease-free survival will be considered on a case-by-case basis

Uncontrolled, symptomatic, intercurrent illness including but not limited to: infections requiring systemic antibiotics, unstable angina pectoris, cardiac arrhythmia, psychiatric illness, or social situations that would limit compliance with study requirements.
