Lung Cancer Clinical Trial
Intratumoral Cisplatin for Resectable NSCLC
Summary
PRIMARY OBJECTIVE:
To identify the maximum tolerated dose (MTD) of intratumoral cisplatin, delivered during a single bronchoscopy with cone-beam CT confirmation, in a dose escalation protocol
DESIGN: 3+3 dose escalation.
Full Description
Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death in the United States. Even for early stage disease, the rate of recurrence following surgical resection is as high as 50%. Although neoadjuvant therapy, administered before surgery, for early stage lung cancer is associated with a survival benefit, it is rarely used due to the systemic toxicity of intravenous (IV) cytotoxic chemotherapy. IV immunotherapies are also being evaluated in combination with systemic therapies in the neoadjuvant setting. However, only a minority of patients respond to immunotherapy. One of the most common reasons for failure of immunotherapy is lack of presentation of tumor antigens to the immune system, a problem that may be potentially addressed with cytotoxic agents.
Over the last several years, case series have demonstrated the feasibility and safety of delivering cisplatin directly into lung tumors. Given the current knowledge of safety and tolerability of intratumoral cisplatin, coupled with the potential to achieve immune priming that may help address systemic micrometastases, the investigators postulate that intratumoral cisplatin will be well-tolerated, and potentially effective, neoadjuvant therapy for patients with early stage, resectable, non-small cell lung cancer.
Eligibility Criteria
Inclusion Criteria:
Age ≥18 years.
Eastern Cooperative Oncology Group performance status 0 or 1
Patients must have adequate organ and marrow function as defined below:
Leukocytes ≥3,000/microliter
Platelets ≥100,000/microliter
Total bilirubin ≤ institutional upper limit of normal (ULN)
Aspartate aminotransferase /Alanine aminotransferase ≤3 × institutional upper limit of normal
Creatinine ≤ institutional ULN
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
Have known or suspected clinical stage I-IIb NSCLC after computed tomography (CT) and/or positron emission tomography at time of enrollment
Presence of a target lesion with a minimum volume of 1.0 cm3, (approximately1.2 cm in diameter) and ≤ 5.0 cm in diameter
Agreement from a cardiothoracic surgeon, following review of past medical history, medications, pulmonary function testing, and CT scan that patient is likely to be a surgical candidate and that, after considering known possible adverse events, delivery of intratumoral cisplatin is unlikely to adversely affect surgical feasibility
Rapid on-site cytopathologic examination (ROSE) performed during the procedure returns likely NSCLC (per the determination of a trained, attending, cytopathologist). No research procedures will be performed if ROSE is non-diagnostic
A CT scan of the chest (with or without contrast) within 1 month of the screening visit
Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria:
Use of an investigational agent within 30 days of the screening visit
IV chemotherapy within the 30 days of the screening visit
Pregnancy/lactation (pregnancy test to be performed by pre-op as part of standard of care for women of child-bearing age as defined by University of Vermont Medical Center Policy
History of prior radiation to the study lesion
History of allergic reaction to cisplatin or its derivatives
Patients with uncontrolled intercurrent illness
Physician determination that patient would not be appropriate for study
