Mithramycin for Lung, Esophagus, and Other Chest Cancers

NCT01624090

Description:

Background: - Mithramycin is a drug that was first tested as a cancer therapy in the 1960s. It acted against some forms of cancer, but was never accepted as a treatment. Research suggests that it may be useful against some cancers of the chest, such as lung and esophageal cancer or mesothelioma. Researchers want to see if mithramycin can be used to treat these types of cancer. Objectives: - To see if mithramycin is safe and effective against different chest cancers. Eligibility: - Individuals at least 18 years of age who have lung, esophagus, pleura, or mediastinum cancers. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies and tumor tissue samples will be used to monitor the cancer before treatment. - Participants will receive mithramycin every day for 7 days, followed by 7 days without treatment. Each 14-day round of treatment is called a cycle. - Treatment will be monitored with frequent blood tests and imaging studies. - Participants will continue to take the drug for as long as the side effects are not severe and the tumor responds to treatment.

Detailed Description

      Background:

      Increasing evidence indicates that activation of stem cell gene expression is a common
      mechanism by which environmental carcinogens mediate initiation and progression of thoracic
      malignancies. Similar mechanisms appear to contribute to extra-thoracic malignancies that
      metastasize to the chest. Utilization of pharmacologic agents, which target gene regulatory
      networks mediating stemness may be novel strategies for treatment of these neoplasms. Recent
      studies performed in the Thoracic Epigenetics Laboratory, TGIB/NCI, demonstrate that under
      exposure conditions potentially achievable in clinical settings, mithramycin diminishes stem
      cell gene expression and markedly inhibits growth of lung and esophageal cancer and MPM
      cells in vitro and in vivo. These finding add to other recent preclinical studies
      demonstrating impressive anti-tumor activity of mithramycin in epithelial malignancies and
      sarcomas that frequently metastasize to the thorax.

      Primary Objective:

      -To assess clinical response rates of mithramycin administered as 6 hour intravenous
      infusions in patients with malignancies involving lungs, esophagus, pleura, or mediastinum.

      Eligibility:

        -  Patients with measurable inoperable, histologically confirmed primary lung and
           esophageal carcinomas, thymic neoplasms, germ cell tumors, malignant pleural
           mesotheliomas or chest wall sarcomas, as well as patients with gastric, colorectal or
           renal cancers and sarcomas metastatic to the thorax are eligible.

        -  Patients with germline SNPs in ABCB4 and ABCB11 that are associated with resistance to
           mithramycin-induced hepatotoxicity.

        -  Patients must have had or refused first-line standard therapy for their malignancies.

        -  Patients must be 18 years or older with an ECOG performance status of 0 2, without
           evidence of unstable or decompensated myocardial disease. Patients must have adequate
           pulmonary reserve evidenced by FEV1 and DLCO equal to or greater than 30% predicted;
           pCO(2) less than 55 mm Hg and pO(2) greater than 60 mm Hg on room air ABG.

        -  Patients must have a platelet count greater than 100,000, an ANC equal to or greater
           than 1500 without transfusion or cytokine support, a normal PT, and adequate hepatic
           function as evidenced by a total bilirubin of <1.5 times upper limits of normal (ULN)
           and AST/ALT less than or equal to 3 x ULN. Serum creatinine less than 3 or equal to 1.6
           mg/ml, or creatinine clearance greater than 70 ml/min/1.73m^2.

      Design:

        -  Simon Optimal Two Stage Design for Phase II Clinical Trials targeting an objective
           response rate (RECIST) of 30%.

        -  Patients will be stratified based on location of primary disease (thoracic vs.
           extra-thoracic).

        -  Patients will receive 6 hour infusions of mithramycin at 30 -50 mcg/kg every day for 7
           days, every 21 days (1 cycle). Three cycles will constitute one course of therapy.
           Those patients tolerating 30 mcg/kg infusions during the first cycle will receive
           subsequent cycles of mithramycin at a dose of 50 mcg/kg using the same infusion
           schedule.

        -  Following each course of therapy, patients will undergo restaging studies. Patients
           exhibiting objective response to therapy or stable disease by RECIST criteria will be
           offered an additional course of therapy.

        -  Patients exhibiting disease progression will be removed from study.

        -  Biopsies of index lesions will be obtained at baseline and on day 8 of the second cycle
           of

      therapy for analysis of molecular end-points.

      -Pharmacokinetics will be assessed during cycle 1 and cycle 2 of the first course of
      therapy.
