Brief summary
This clinical study will help determine if giving OGX-011 (custirsen sodium) in combination with gemcitabine (GEM) and cisplatin (CIS) or carboplatin (CARB) is a safe and effective treatment for patients with lung cancer. This study will help to assess the safety and anti-tumor effect of OGX-011 when given to patients in combination with GEM and CIS/CARB.
Detailed description
OGX-011 is an experimental drug that has been shown to increase the effectiveness of commonly used cancer therapies such as chemotherapy, radiation and hormone therapy in several kinds of cancer types in animals. OGX-011 is being studied in the treatment of cancer patients in combination with chemotherapy. In humans, OGX-011 in combination with hormone therapy has been shown to decrease the tissue levels of a protein called clusterin, which can be overproduced in cancer cells. Clusterin has been found to block cell death and makes cells more resistant to cancer therapy. Gemcitabine (GEM), cisplatin (CIS) and carboplatin (CARB) have been approved by Health Canada and the Food and Drug Administration in the United States for the treatment of patients with lung cancer. OGX-011 was administered as a 2-hr intravenous (IV) infusion on Days -7, -5, and -3 prior to Cycle 1, then weekly on Days 1, 8, 15 of each 21-day cycle; GEM was infused IV after OGX-011 on Days 1 and 8; either CIS or CARB was infused IV after GEM on Day 1 of each cycle. Six cycles of treatment were planned. Most patients received OGX-011 at 640 mg, but 3 patients received OGX-011 at 480 mg dose; OGX-011 dose groups were combined due to the small number of patients who received 480 mg.
Interventions
Custirsen sodium (OGX-011) was to be infused intravenously over 2 hours on Days -7, -5, and 3 of Cycle 1 (pretreatment loading dose). OGX 011 was then to be infused for 2 hours weekly on Days 1, 8, and 15 of a 21-day cycle. Gemcitabine (GEM) was to be infused intravenously for 30 minutes on Days 1 and 8 and either cisplatin (CIS) or carboplatin (CARBO) were to be infused intravenously on Day 1 of this 21-day cycle. Patients were to receive a maximum of 6 cycles (1 cycle = 21 days)

|---|---|---|
| Objective Response Rate of OGX-011 in Combination With Gemcitabine/Platinum-based Regimen | Based on assessments at baseline and after Cycles 2, 4, and 6. All subjects were followed for survival for a minimum of 3 years after the first dose of OGX-011 or until death. | Per RECIST Criteria V 1.0 and based on radiographic evaluations a subject was defined as having an objective response (OR) if the subject achieved either a confirmed partial response (PR) or confirmed complete response (CR). The evaluations were conducted after every two cycles of treatment for a maximum of 6 cycles. CR: disappearance of clinical/radiological evidence of tumor. PR: \>= 30% decrease in the sum of the longest diameter of target lesions. SD: did not fulfill the criteria for CR or PR but not progressive disease. |

|---|---|---|
| Overall Survival | All subjects were followed for a minimum of 3 years after the first dose of OGX-011 or until death. | Overall survival was defined as time from date of first treatment with OGX-011 to the date of death from any cause. Overall survival was censored at date of last contact for subjects who were still alive at end of study. |
| Effect of OGX-011 on Serum Clusterin Levels | Blood samples were collected at baseline and prior to infusion on Cycle 2 Day 1 and Cycle 3 Day 1 | To measure the effect of OGX-011 on serum clusterin levels. The drug substance, OGX-011, is an antisense product designed to bind to clusterin mRNA, resulting in the inhibition of the production of human clusterin protein. Therefore, serum clusterin levels were expected to decrease. |
