Brief Summary:

Background:

  • Malignant mesothelioma is a form of cancer that develops on the protective lining that covers the body's internal organs. It most often occurs on the lining of the lungs and chest wall or the lining of the abdomen. There is no known cure for malignant mesothelioma, so researchers are searching for new ways to treat it.
  • Mesothelin is a protein that is found in mesothelioma and other types of cancer cells. An experimental cancer drug called SS1P is designed to attack cells that have mesothelin while leaving healthy cells alone. Researchers want to test how effective SS1P is when it is given with pentostatin and cyclophosphamide. These drugs help suppress the immune system and may make the SS1P more effective.

Objectives:

- To study the effectiveness of SS1P plus two drugs that suppress the immune system to treat malignant mesothelioma.

Eligibility:

- Individuals at least 18 years of age who have malignant mesothelioma in the chest or abdomen.

Design:

  • Participants will be screened with a physical exam, medical history, and blood tests. They will also have imaging studies.
  • The first treatment cycle will last 30 days. Up to three 21-day cycles of treatment will follow.
  • In the first cycle, participants will have pentostatin on days 1, 5, and 9. They will have cyclophosphamide on days 1 through 12. They will have SS1P on days 10, 12, and 14.
  • On the next three cycles, participants will have pentostatin on day 1.They will have cyclophosphamide on days 1 through 4. They will have SS1P on days 2, 4, and 6.
  • Participants will have frequent blood tests and other studies. They will receive all four cycles of treatment as long as there are no severe side effects.
  • Participants will have regular followup visits as directed by the study doctors.

Primary Outcome Measures :
  1. Response Assessment [ Time Frame: 52 months and 4 days ]
    Response was assessed by the European Organization for Research and Treatment of Cancer (EORTC) modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Complete response (CR) is complete disappearance of all target lesions. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions. Progressive disease (PD) disease is at least a 20% increase in the sum of the LD of target lesions. Stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.

  2. Count of Participants With SS1P Antibody Formation [ Time Frame: On last day of last dosing cycle, end of cycle 1 (day 30) ]
    Development of antibodies following treatment with SS1P. The goal was to delay development of antibodies to SS1P so a patient could get a second cycle of therapy with SS1P.

  3. Count of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0) Who Were Administered SS1P and Pentostatin or Cyclophosphamide [ Time Frame: Date treatment consent signed to date off study, approximately 64 months and 26 days ]
    Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

  4. Recommended Phase 2 Dose (RP2D) in Drug Lot FIL129J01 [ Time Frame: Days 1, 3, and 5 of a 21 day cycle ]
    Should any 2 patients within the first 3 to 6 patients experience treatment limiting toxicity requiring cessation of treatment prior to the conclusion of the first cycle, the maximum tolerated dose will have been exceeded and patients will be enrolled to the next lower dose.


Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: 36 months ]
    The Kaplan-Meier was used to determine the probability of overall survival from on-study date until death or last follow-up (calculated from the date of study entry until the date of analysis).

  2. Progression-free Survival [ Time Frame: 36 months ]
    Defined as the time interval from the start of treatment to documented evidence of disease progression. Progressive disease is assessed by the European Organization for Research and Treatment of Cancer (EORTC) modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria, and is at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum on study LD (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. (Note: the appearance of one or more new lesions is also considered progression).

  3. Duration of Response [ Time Frame: up to 2.5 years ]
    DOR is assessed by the European Organization for Research and Treatment of Cancer (EORTC) modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria and is measured from the time measurement criteria is met for complete response or partial response (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Complete response is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to<10mm. partial response is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. Progressive disease is at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum on study LD (this includes the baseline sum if that is the smallest on study).


Other Outcome Measures:
  1. Count of Participants SS1P Cycles Received Following Onstudy [ Time Frame: Cycles 1-6, up to 180 days ]
    Here are the number of participants who had SS1P cycles during cycle 1-6.

  • The effects of SS1(dsFv)PE38, pentostatin, and cyclophosphamide on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (barrier method of birth control; abstinence) for the duration of study therapy and for 3 months after the last dose of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. While hormonal methods of birth control are effective, we ask that female patients who are participating in the study cease hormonal forms of birth control, as these methods of birth control (birth control pills, injections, or implants) may affect the study drug. Patients must be off hormonal forms of birth control for at least 4 weeks prior to initiating the study.
  • Ability to comply with intravenous administration schedule, and the ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA: (All Subjects)

  • Patients with symptomatic 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. However, patients who have had treatment for their brain metastases and whose brain metastatic disease status has remained stable for at least 4-6 weeks without steroids may be enrolled at the discretion of the principal investigator.
  • Uncontrolled medical illness including, but not limited to, ongoing or uncontrolled, symptomatic congestive heart failure (American Heart Association (AHA) Class II or worse), uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Human immunodeficiency virus (HIV) positive patients will be excluded due to a theoretical concern that the degree of immune suppression associated with the treatment may result in progression of HIV infection.
  • Patients with Hepatitis B and C will be excluded.
  • Serum neutralization antibody assay shows greater than or equal to 75% neutralization of the SS1 (dsFv) PE38 activity at 200 ng/ml.
  • Patients may not be receiving any other investigational agents.
  • History of another invasive malignancy in the last two years. Adequately treated noninvasive, non-melanoma skin cancers as well as in situ carcinoma of the cervix will be allowed.
  • Prior treatment with drugs of the immunotoxin class.
  • Patients with tumor amenable to potentially curative therapy as assessed by the investigator.
  • Pregnant women are excluded from this study because SS1(dsFv)PE38, pentostatin, and cyclophosphamide have the potential for teratogenic or abortifacient effects. The agents in the trial may also potentially be secreted in milk and therefore breastfeeding women should be excluded. Because of the potential of teratogenic or abortifacient effects women of childbearing potential and men must agree to use adequate contraception (barrier methods) before, during the study and for a period of 3 months after the last dose of the investigational agent.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to SS1(dsFv)PE38.

INCLUSION CRITERIA: WOMEN AND MINORITIES

-Both men and women and members of all races and ethnic groups are eligible for this trial. Every effort will be made to recruit women and minorities in this study.
