| 参加者の流れ/Participant flow | 全登録例131例のうち、66例が標準治療A群(以下、A群とする)に、65例が試験治療B群(以下、B群とする)に割り付けられた。このうち、A群では治療非施行1例及び不適格例1例が、B群では治療非施行1例が除外され、FASはA群で64例、B群で64例であった。
安全性解析の一環として、全治療例におけるプロトコール治療のコース数を算出した。最終コース数の中央値はA群2.0コース、B群4.0コースであった。最小値及び最大値はそれぞれ、A群1コース及び28コース、B群1コース及び31コースであった。 A群ではFAS 64例中60例が、B群では同64例中62例が試験治療を中止した。最も多かった中止理由はA、B群ともにプロトコール治療無効と判断であった[A群46例(71.9%)、B群33例(51.6%)]。次いで、A群では患者希望(有害事象と関連が否定できる)が7例(10.9%)、B群では有害事象によりプロトコール治療の継続不可が25例(39.1%)であった。 |
Of the 131 patients enrolled, 66 patients were assigned to standard treatment group A (hereinafter referred to as Group A) and 65 patients to study treatment group B (hereinafter referred to as Group B). Of these, one treatment-naive and one ineligible patient were excluded from Group A, and one treatment-naive patient was excluded from Group B, therefore FAS was 64 patients in Group A and 64 patients in Group B.
As part of the safety analysis, the number of protocol treatment courses was calculated for all treated patients. The median number of the previous courses was 2.0 in Group A and 4.0 in Group B. The minimum and maximum values were one course and 28 courses in Group A, one course and 31 courses in Group B, respectively. Sixty of 64 FAS patients in Group A and 62 of 64 FAS patients in Group B discontinued the study treatment. The most common reason for discontinuation was failure of protocol treatment in both Groups A and B [46 patients (71.9%) in Group A and 33 patients (51.6%) in Group B]. The next most common reason was patient preference (not related to adverse events) in seven patients (10.9%) in Group A, and unable to continue protocol treatment due to adverse events in 25 patients (39.1%) in Group B. |

Phase III part: - The incidence of adverse events was evaluated as the secondary endpoint. In Group A, common events included hypoalbuminemia in 33 patients (50.8%), malaise in 20 patients (30.8%), anemia in 17 patients (26.2%), and increased creatinine in 17 patients (26.2%).

Phase II part:
- Six-month progression-free survival rate was evaluated as the primary endpoint. The number of events was 29 in Group A and 16 in Group B. The 6-month progression-free survival rate and its 80% CI were 22.4% [13.2, 33.2)] in Group A and 64.4% [53.4, 73.5] in Group B, respectively. - Response rate was evaluated as the secondary endpoint. The number, proportion, and its 95% CI of patients with a best overall response of either complete response (CR) or partial response (PR) were five patients in Group A (10.2% [3.4, 22.2]) and 12 patients in Group B (24.5% [13.3, 38.9]). Phase III part: - Overall survival was evaluated as the primary endpoint. The number of events was 42 (65.6%) in Group A and 33 (51.6%) in Group B. The median survival and its 95% CI were 14.7 months [11.4, 18.7] in Group A and 23.1 months [16.7, -] in Group B. Twelve-month survival rate and its 95% CI were 58.6% [45.1, 69.8] in Group A, 71.4% [58.5, 80.9] in Group B, and 24-month survival rate and its 95% CI were 32.9% [21.1, 45.3] in Group A and 47.7% [34.3, 60.0] in Group B. For the stratified log-rank test, the difference was statistically significant (p = 0.0310) at the 5% significance level of alpha (one sided). Using the stratified Cox regression model, the adjusted hazard ratio of Group B against Group A and its 90% CI were 0.63 [0.42, 0.95]. Therefore, study treatment B significantly improved overall survival compared with standard treatment A. - The subgroup analysis of overall survival was conducted as the exploratory analysis of the primary endpoint. The subgroup factors were histological type (squamous cell carcinoma, non-squamous cell carcinoma), PS (0, 1), clinical stage (stage IIIB, stage IV, postoperative recurrence), sex (male, female), EGFR gene mutation or ALK gene translocation (absence, presence), number of prior chemotherapy regimens (1, 2), smoking history (absence, presence), and PD-L1 (28-8) expression rate (three categories: 0, 1-49, and >= 50%). In the subgroup analysis, study treatment B also significantly improved overall survival compared with standard treatment A, except for the number of prior chemotherapy regimens (2) and PD-L1 (28-8) expression rate (>= 50%), where the number of patients was small. There appeared to be no interaction between subgroup factor. - Progression-free survival was evaluated as the secondary endpoint. The number of events was 54 (84.4%) in Group A and 55 (85.9%) in Group B. The median progression-free survival and its 95% CI were 3.1 months [2.0, 3.9] in Group A and 6.7 months [3.8, 9.4] in Group B. Six-month progression-free survival rate and its 95% CI were 26.4% [16.0, 37.9] in Group A, 56.3% [43.3, 67.4] in Group B, Twelve-month progression-free survival rate and its 95% CI were 15.8% [7.9, 26.3] in Group A and 22.6% [13.2, 33.5] in Group B, and 24-month progression-free survival rate and its 95% CI were 12.1% [5.2, 22.0] in Group A and 15.4% [7.6, 25.7] in Group B. For the stratified log-rank test, the difference was statistically significant (p = 0.0095) at the 5% significance level of alpha (two sided). Using the stratified Cox regression model, the adjusted hazard ratio of Group B against Group A and its 95% CI were 0.58 [0.39, 0.88]. Therefore, study treatment B significantly improved progression-free survival compared with standard treatment A. - Response rate was evaluated as the secondary endpoint. Regarding the best overall response, CR was not observed in any patients in Group A and in one patient (1.8%) in Group B, PR was observed in eight patients in Group A (14.0%) and in 22 patients in Group B (40.0%), and the response rate and its 95% CI were eight patients in Group A (14.0%, 95% CI [6.3, 25.8]) and 23 patients in Group B (41.8%, 95% CI [28.7, 55.9]). The Fisher's exact test for the response rate was p = 0.0014, indicating a statistically significant difference. Therefore, study treatment B significantly improved the response rate compared with standard treatment A. |
