Study Endpoints

Primary Endpoints

Overall Survival: All Randomized Population
From randomization to death or last known date alive (up to 1331 days for Docetaxel arm and up to 1271 days for Docetaxel + Custirsen arm)

Overall survival time is defined as the number of days from the date of randomization until the date of death from any cause. Participants who did not achieve the event (death) at the time of the analysis or who dropped out before completing the survival follow-up period will be censored at the date they were last known to be alive (i.e., right censored). Partial or missing dates of death or last contact were imputed.

Overall Survival: Stratified by Histology - Squamous vs. Non-Squamous
From randomization to death or last known date alive (up to 1331 days for Docetaxel arm and up to 1271 days for Docetaxel + Custirsen arm)

Overall survival time is defined as the number of days from the date of randomization until the date of death from any cause. Participants who did not achieve the event (death) at the time of the analysis or who dropped out before completing the survival follow-up period will be censored at the date they were last known to be alive (i.e., right censored). Partial or missing dates of death or last contact were imputed.

Survival in the intent-to-treat population
3.4 years

To determine whether the survival for patients randomized to the investigational arm (cabazitaxel/prednisone plus custirsen) is consistent with longer survival as compared to patients randomized to the control arm (cabazitaxel/prednisone).

Survival in the poor-prognosis patient population
2.7 years

To determine whether the survival for patients randomized to the investigational arm (cabazitaxel/prednisone plus custirsen) and identified as having poor prognosis is consistent with longer survival as compared to patients randomized to the control arm (cabazitaxel/prednisone) and identified as having poor prognosis.

Kaplan-Meier Estimates for Time to Death (Overall Survival)
Randomization (approximately Day -12) to longest survival follow-up (Day 971).

Time from the date of randomization to death from any cause. After stopping treatment, patients were followed every 4 weeks until disease progression and then followed every 12 weeks until death.

Safety and Tolerability of Custirsen (OGX-011) in Combination With Either Docetaxel/Prednisone or Mitoxantrone/Prednisone as Second-line Chemotherapy.
Subjects were followed for safety from enrollment for up to 8 months (9 three-week cycles plus 30 days after end of treatment)

Safety and tolerability were based on Adverse Events (AE) and Serious Adverse Events (SAE) graded using National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE). The CTCAE has 5 grades with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1=Mild AE; Grade 2=Moderate AE; Grade 3=Severe AE; Grade 4=Life-threatening or disabling AE; and Grade 5=Death related to AE.

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.

Individually-corrected QT interval (QTcI)
Up to 23.5 hours after the start of study drug infusion on Day 7

The primary ECG variable and endpoint for this study is the time-matched change from baseline in QTcI method on day 7 at each time point. Holter ECGs will be performed at baseline (day -1) and prior to the start of infusion on day 7 and 1, 2 (end of infusion), 2.5, 3, 4, 5, 6, 8, 12, 16, 20, and 23.5 hours after the start of infusion.

To evaluate the impact of custirsen on paclitaxel pharmacokinetics
0, 1, 2, 3, 3.25, 3.67, 4.5, 6, 8, 12, 24 and 48 hours after the start of paclitaxel infusion

Frequently asked questions about Custirsen, paclitaxel and carboplatin

What is custirsen, paclitaxel and carboplatin?

Custirsen, paclitaxel and carboplatin is a combination treatment regimen that pairs the investigational antisense drug custirsen with two chemotherapy agents, paclitaxel and carboplatin. It has been studied in cancer, including non-small cell lung cancer, and is being developed by Achieve Life Sciences, Inc. (ticker QUIT).

What does custirsen target?

Custirsen targets clusterin, encoded by the CLU gene. It is an antisense inhibitor, an RNA-based therapy designed to bind clusterin RNA and reduce clusterin production. In this regimen it is combined with paclitaxel and carboplatin chemotherapy in patients with cancer.

Who makes custirsen, paclitaxel and carboplatin?

Custirsen, paclitaxel and carboplatin is being developed by Achieve Life Sciences, Inc., which trades under the ticker QUIT. The company is the sponsor associated with the clinical development program for custirsen in combination with chemotherapy.

What phase is custirsen, paclitaxel and carboplatin in?

Custirsen, paclitaxel and carboplatin is in Phase 1 development. Custirsen itself has also been studied in Phase 3 trials in non-small cell lung cancer and prostate cancer. It is an investigational agent and is not described as FDA approved for this combination regimen.

What clinical trials is custirsen, paclitaxel and carboplatin in?

The Phase 1 trial NCT01497470 studied custirsen with paclitaxel in cancer patients to assess the impact of custirsen on paclitaxel blood levels. Related custirsen trials include the Phase 3 NSCLC study NCT01630733, the Phase 3 prostate cancer study NCT01578655, and the cardiac repolarization study NCT01874561.

Is custirsen the same as custirsen sodium or OGX-011?

Yes. Custirsen is also known as custirsen sodium and by the designation OGX-011. The combination regimen custirsen, paclitaxel and carboplatin refers to the same custirsen compound given alongside those two chemotherapy drugs.
