Study Details

Study Description

Brief Summary

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, Thoracic and Oncology Surgery Branch (TOSB)/National Cancer Institute (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 malignant pleural mesothelioma (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 single nucleotide polymorphisms (SNPs) in adenosine 5-triphosphate binding cassette subfamily B member 4 (ABCB4), adenosine 5-triphosphate binding cassette subfamily B member 11 (ABCB11), retinal-binding protein (RALBP) or cytochrome P851 (CYP851) 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 Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, without evidence of unstable or decompensated myocardial disease. Patients must have adequate pulmonary reserve evidenced by forced expiratory volume 1 (FEV1) and diffusing capacity for carbon monoxide (DLCO) equal to or greater than 30% predicted; oxygen saturation greater than or equal to 92% on room air. Arterial Blood Gas (ABG) will be drawn if clinically indicated.

• Patients must have a platelet count greater than 100,000, an absolute neutrophil count (ANC) equal to or greater than 1500 without transfusion or cytokine support, a normal prothrombin time (PT)/partial thromboplastin time (PTT), and adequate hepatic function as evidenced by a total bilirubin of <1.5 times upper limits of normal (ULN) and aspartate aminotransferase (AST)/alanine aminotransferase (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 (Response Evaluation Criteria in Solid Tumors (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.

Arms and Interventions

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 Names: Mithracin

Outcome Measures

Primary Outcome Measures

1. Number of Participants With an Objective Response (Complete Response + Partial Response) [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 [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.
