Brief summary

The purpose of this study is to determine whether NK012 is safe and effective in the treatment of refractory solid tumors

Detailed description

This is a Phase I dose-escalation study of the intravenous administration of NK012 in patients with refractory solid tumors. Patients will receive NK012 as an intravenous infusion over 30 minutes on Day 1 followed by a 20-day observation period for a total of 21 days (3 weeks) per cycle. Two patient populations will be evaluated separately: patients with UGT1A1\*28 genotype homozygous wild type (wt/wt) and heterozygous (wt/\*28) variants as one group, and patients with UGT1A1\*28 homozygous variant (\*28/\*28) as another group.

Interventions

Inclusion criteria

* Histologically confirmed malignant solid tumor for which there are no known regimens or protocol treatments of higher efficacy or priority * Failed conventional therapy for the cancer or have a malignancy for which a conventional therapy does not exist * Recovered from all acute adverse effects of prior therapies, excluding alopecia (hair loss) * Life expectancy of at least 12 weeks and an EOCG performance status of 0 or 1 * 18 years of age or older * Adequate kidney, liver, and bone marrow function * Ability to understand and the willingness to sign a written informed consent document

Exclusion criteria

* Have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or have not recovered from adverse effects due to agents administered more than 4 weeks earlier * Receiving any other investigational agent * 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 * History of allergic reactions attributed to compounds of similar chemical composition to NK012 * Concurrent serious infections (i.e., requiring an intravenous antibiotic) * Pregnant women or women of childbearing potential who are not using methods to avoid pregnancy; a negative pregnancy test (urine or serum) must be documented at baseline and before every NK012 administration for women of childbearing potential; no breast-feeding while on study * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, unstable angina pectoris or psychiatric illness/social situations that would limit compliance with study requirements * Significant cardiac disease * History of serious ventricular arrhythmia * Positive for anti-HbsAg, anti-HCV, anti-HIV, or anti-syphilis antibodies

Design outcomes

Primary

MeasureTime frameDescription
Dose-limiting toxicity of NK012 in patients with UGT1A1*28 (wt/wt and wt/*28) genotypeAt the end of Cycle 1 (each cycle is 21 days)
Maximum tolerated dose of NK012 in patients with UGT1A1*28 (wt/wt and wt/*28) genotypeAt the end of Cycle 1 (each cycle is 21 days)
Recommended phase II dose of NK012 in patients with UGT1A1*28 (wt/wt and wt/*28) genotypeAt the end of Cycle 1 (each cycle is 28 days)After MTD was determined, the administration schedule was changed to every 28 days per cycle, considering patient safety.
