About

The purpose of this study is to determine whether NK012 is safe and effective in the treatment of relapsed small cell lung cancer.

Full description

This is a Phase II, open label, single arm, multicenter study of NK012 in patients with sensitive relapsed SCLC (at least 90 days since first line therapy) or refractory relapsed SCLC (< 90 days since first line therapy). NK012 will be administered by intravenous infusion over 30 minutes once every 28 days (on Day 1 of each cycle). Patients will be screened for UGT1A1 polymorphism prior to enrollment.

Enrollment: 72 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Histologically or cytologically confirmed diagnosis of SCLC, which has relapsed after first line chemotherapy for extensive-stage SCLC or first-line chemoradiotherapy for limited-stage SCLC.
2. Have received one, and only one, prior chemotherapy or chemoradiotherapy regimen for either newly diagnosed extensive-stage disease or limited-stage disease.
3. Prior therapies must be completed at least 4 weeks prior to enrollment and patients must have recovered from all acute toxicities.
4. Measurable disease by RECIST.
5. ECOG performance status of 0-2.
6. At least 18 years of age.
7. Adequate bone marrow function as defined by absolute neutrophil count of greater than or equal to 1,500/mm^3 and platelets of greater than or equal to 100,000/mm^3.
8. AST (SGOT) and ALT (SGPT) levels no greater than 3 x the institutional ULN, and total bilirubin less than or equal to 1.5 x ULN.
9. Serum creatinine less than or equal to 1.5 x ULN, or creatinine clearance greater than or equal to 60 mL/min (Cockcroft-Gault formula) for patients with serum creatinine levels > 1.5 x ULN.
10. Able to understand and show willingness to sign a written informed consent document.

Exclusion criteria

1. Patient has Gilbert's Syndrome.
2. Prior chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study.
3. Lack of recovery from adverse effects due to agents administered more than 4 weeks prior to study entry.
4. Concurrent use of other investigational agent.
5. History of brain metastases or spinal cord compression, unless irradiated a minimum of 4 weeks before study entry and stable without requirement for corticosteroids for > 1 week.
6. Prior exposure to topoisomerase 1 inhibitors (i.e., irinotecan, topotecan, camptothecin).
7. Concurrent serious infections requiring parenteral therapy.
8. Pregnant or of childbearing potential and not using methods to avoid pregnancy. A negative pregnancy test (urine or serum) must be documented at baseline for women of childbearing potential. Patients may not breast-feed infants while on this study.
9. Significant cardiac disease including heart failure that meets New York Heart Association (NYHA) class III and IV definitions, history of myocardial infarction within one year of study entry, uncontrolled dysrhythmias or poorly controlled angina.
10. History of serious ventricular arrhythmia (VT or VF, greater than or equal to 3 beats in a row), QTc greater than or equal to 450 msec for men and 470 msec for women, or LVEF less than or equal to 40% by MUGA or ECHO.
