Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Best Overall Tumor Response | baseline to measured progressive disease (up to 2 years follow-up) | Best response recorded from the start of treatment until disease progression/recurrence using Response Evaluation Criteria In Solid Tumors (RECIST) criteria that defines when participants improve (respond), stay the same (stable), or worsen (progression) during treatment. Complete response (CR) = disappearance of all target lesions. Partial response (PR) = 30% decrease in the sum of the longest diameter of target lesions. Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions. Stable disease (SD) = small changes that do not meet above criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response | time of response to progressive disease or death (up to 2 years follow-up) | The duration of a complete response (CR) or partial response (PR) was defined as the time from first objective status assessment of CR or PR to the first time of progression or death as a result of any cause. Response was determined using Response Evaluation Criteria In Solid Tumors (RECIST) criteria that defines when participants improve (respond), stay the same (stable), or worsen (progression) during treatment. Complete response (CR) = disappearance of all target lesions. Partial response (PR) = 30% decrease in the sum of the longest diameter of target lesions. |
| Progression-Free Survival (PFS) | baseline to measured progressive disease or death (up to 2 years follow-up) | Defined as the time from study enrollment to the first date of disease progression or death as a result of any cause. PFS was censored at the date of the last follow-up visit for participants who were still alive and who had not progressed. |
| Time to Treatment Failure | baseline to stopping treatment (up to 2 years follow-up) | Defined as the time from study enrollment to the first observation of disease progression, death as a result of any cause, or early discontinuation of treatment. Time to treatment failure was censored at the date of the last follow-up visit for patients who did not discontinue early, who were still alive, and who have not progressed. |
| Overall Survival | baseline to date of death from any cause (up to 2 years follow-up) | Overall survival is the duration from enrollment to death. For patients who are alive, overall survival is censored at the last contact. |

Participant flow
Pre-assignment details
Two participants discontinued the trial before receiving study treatment. One due to entry criteria exclusion and one due to withdrawal by subject. Therefore, 44 participants received at least one dose of chemotherapy and are included in the efficacy and safety analyses.

Outcome results
Best Overall Tumor Response
Best response recorded from the start of treatment until disease progression/recurrence using Response Evaluation Criteria In Solid Tumors (RECIST) criteria that defines when participants improve (respond), stay the same (stable), or worsen (progression) during treatment. Complete response (CR) = disappearance of all target lesions. Partial response (PR) = 30% decrease in the sum of the longest diameter of target lesions. Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions. Stable disease (SD) = small changes that do not meet above criteria.
Time frame: baseline to measured progressive disease (up to 2 years follow-up)
Population: All enrolled participants with at least one completed cycle.
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Pemetrexed + Irinotecan | Best Overall Tumor Response | Progressive Disease | 15 participants |
| Pemetrexed + Irinotecan | Best Overall Tumor Response | Unknown | 5 participants |
| Pemetrexed + Irinotecan | Best Overall Tumor Response | Partial Response | 6 participants |
| Pemetrexed + Irinotecan | Best Overall Tumor Response | Stable Disease | 18 participants |
Duration of Response
The duration of a complete response (CR) or partial response (PR) was defined as the time from first objective status assessment of CR or PR to the first time of progression or death as a result of any cause. Response was determined using Response Evaluation Criteria In Solid Tumors (RECIST) criteria that defines when participants improve (respond), stay the same (stable), or worsen (progression) during treatment. Complete response (CR) = disappearance of all target lesions. Partial response (PR) = 30% decrease in the sum of the longest diameter of target lesions.
Time frame: time of response to progressive disease or death (up to 2 years follow-up)
Population: All enrolled participants with at least completed cycle and who had a complete or partial response.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Pemetrexed + Irinotecan | Duration of Response | 236 days |
Overall Survival
Overall survival is the duration from enrollment to death. For patients who are alive, overall survival is censored at the last contact.
Time frame: baseline to date of death from any cause (up to 2 years follow-up)

|---|---|---|
| Pemetrexed + Irinotecan | Overall Survival | 422 days |

Defined as the time from study enrollment to the first observation of disease progression, death as a result of any cause, or early discontinuation of treatment. Time to treatment failure was censored at the date of the last follow-up visit for patients who did not discontinue early, who were still alive, and who have not progressed.
Time frame: baseline to stopping treatment (up to 2 years follow-up)
Population: All enrolled participants with at least one completed cycle.
