Brief Summary:


- 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.


- To see if mithramycin is safe and effective against different chest cancers.


- Individuals at least 18 years of age who have lung, esophagus, pleura, or mediastinum cancers.


  • 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.

Arm Intervention/treatment
Experimental: 1/mithramycin
Single agent intravenous (IV) mithramycin
Drug: Mithramycin
30 mcg/kg intravenous (IV) over 6 hours once daily for 7 days, to be repeated every 21 days (one cycle) until disease progression or unacceptable toxicity
Other Name: Mithracin

Primary Outcome Measures :
  1. Number of Participants With an Objective Response (Complete Response + Partial Response) [ Time Frame: Every 8 weeks until disease progression or unacceptable toxicity, over an average of 4 months. ]
    Objective response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete Response (CR) 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 (PR) is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesion, taking as reference the smallest sum on study (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 progressions). Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Secondary Outcome Measures :
  1. Number of Participants With Serious and Non-Serious Adverse Events [ Time Frame: Date treatment consent signed to date off study, approx. 9 mos & 6 days DL1 30 mcg/kg thoracic group, 2 mos & 16 days DL1 30 mcg/kg extra-thoracic group, 5 mos & 26 days DL-1 25 mcg/kg thoracic group, & 20 days DL-1 25 mcg/kg extra-thoracic group ]
    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.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
  • Diagnosis: 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
  • Histologic confirmation of disease in the Laboratory of Pathology, Center for Cancer Research (CCR), National Cancer Institute (NCI), National Institutes of Health (NIH).
  • Disease amenable to biopsy via percutaneous approach or other minimally invasive procedures such as thoracoscopy, bronchoscopy, laparoscopy, or gastrointestinal (GI) endoscopy
  • Age >18
  • Eastern Cooperative Oncology Group (ECOG) status 0-2.
  • Patients must have had or refused first-line standard chemotherapy for their inoperable malignancies.
  • Patients must have had no chemotherapy, biologic therapy, or radiation therapy for their malignancy for at least 30 days prior to treatment. Patients may have received localized radiation therapy to non-target lesions provided that the radiotherapy is completed 14 days prior to commencing therapy, and the patient has recovered from any toxicity. At least 3 half-lives must have elapsed since monoclonal antibody treatment. At least six weeks must have elapsed between mitomycin C or nitrosourea treatment.
  • Patients must have adequate organ and marrow function as defined below:

    a) Hematologic and Coagulation Parameters:
