SKYSCRAPER-08: A phase III, randomized, double-blind, placebo-controlled study of first-line (1L) tiragolumab (tira) + atezolizumab (atezo) and chemotherapy (CT) in patients (pts) with esophageal squamous cell carcinoma (ESCC)
SKYSCRAPER-08:一线(1L)tiragolumab(tira)+阿替利珠单抗(atezo)和化疗(CT)治疗食管鳞状细胞癌(ESCC)患者(pts)的III期、随机、双盲、安慰剂对照研究
摘要号:245
背景
TIGIT是一种新型免疫检查点抑制剂,可以通过补充PD-L1/PD-1通路进一步放大免疫反应。食管鳞状细胞癌的免疫疗法已证明其抗肿瘤活性。SKYSCRAPER-08(NCT04540211)正在评估tira(抗TIGIT)+atezo(抗PD-L1)联合CT与安慰剂+CT相比作为一线(1L)治疗(tx)在不可切除的局部晚期(LA)、不可切除的复发性或转移性(R/M)ESCC亚洲人群中的疗效和安全性。
方法
符合条件的患者(确认LA或R/M ESCC);Ecog PS 0-1分;在21天1周期(16周期)的第1天,1:1随机接受tira 600 mg+atezo 1200 mg+CT(紫杉醇175 mg/m2+顺铂6080 mg/m2,当地标准治疗)或安慰剂+CT;随后是tira+atezo或安慰剂维持,直到失去临床益处/不可接受的毒性。主要终点:独立审查机构(IRF)评估的无进展生存期(PFS)和总生存期(OS)。次要终点:研究者(INV)评估的PFS、客观缓解率(ORR)、缓解持续时间(DoR)和安全性。
结果
总体而言,461例患者被随机分配(tira+atezo+CT,n=229;安慰剂+CT,n=232)。患者基线特征在两组间基本平衡。截至2022年6月15日,最低生存期随访6.5个月;经IRF评估的tira+atezo+CT组中位PFS为6.2个月,安慰剂+CT组为5.4个月(HR 0.56;95%CI:0.45-0.70;P<0.0001)。截至2023年2月13日,最短生存期随访14.5个月;OS最终分析,tira+atezo+CT组的中位OS为15.7个月,而安慰剂+CT组的中位OS为11.1个月(HR 0.70,95%CI:0.55-0.88;P=0.0024)。INV评估的PFS、IRF评估的ORR和DoR(见下表)。
结论
该研究满足了IRF评估的PFS和OS的两个主要终点,表明tira+atezo+CT组比安慰剂+CT组在PFS和OS方面有统计学意义和临床意义的改善。总的来说,包括PD-L1状态在内的各个亚组都同样观察到获益。安全性与个体的已知风险一致。

Pembrolizumab plus FLOT vs FLOT as neoadjuvant and adjuvant therapy in locally advanced gastric and gastroesophageal junction cancer: Interim analysis of the phase 3 KEYNOTE-585 study
帕博利珠单抗(Pembrolizumab)联合FLOT vs FLOT作为局部晚期胃癌和胃食管结癌的新辅助和辅助治疗:III期KEYNOTE-585研究的中期分析
摘要号:247
背景
3期KEYNOTE-585研究(NCT03221426)评估了新辅助/辅助帕博利珠单抗(pembro)或安慰剂(pbo)+化疗(chemo),然后辅助pembro与pbo治疗局部晚期、可切除的胃癌或胃食管交界处(G/GEJ)癌。设立了一个单独的队列评估pembro+FLOT(FLOT队列),并在第三次中期分析中报告了FLOT队列的安全性和有效性分析结果。
方法
在FLOT队列中,未经治疗的局部晚期可切除G/GEJ癌症患者(pts)以1:1的比例随机分配至新辅助pembro 200 mg IV Q3W(pembro gp)或pbo(pbo gp)Q3W 3个周期+FLOT(多西他赛、奥沙利铂、亚叶酸和5-FU)Q2W,持续4个周期。手术后,pts接受辅助pembro或pbo Q3W 3个周期+FLOT Q2W 4个周期,然后辅助pembro或pbo Q3W 11个周期。评估的终点包括安全性、pCR率(BICR)、EFS(RECIST 1.1,由研究者提供)和ITT中的OS。第三次中期分析的数据截止时间为2023年2月9日。
结果
共有203例患者被随机分配(100 pembro+FLOT;103 pbo+FLOT)。其中,12例(6%)患者为cT1-T2,161例(79%)为cT3,9例(4%)为cT4。140例(69%)基线时为N+,79例(39%)患有GEJ腺癌。IA3的中位随访时间分别为31.6个月和31.1个月。99例中有94例(95%)完成了新辅助治疗,99例中有87例(87%)完成了手术阶段,77例中有45例(58%)完成了辅助治疗。pembro gp和pbo gp的R0切除率分别为79%和80%。
pembro gp的pathCR率为17.0%(95%CI:10.2-25.8),pbo gp为6.8%(95%CI:2.8-13.5),估计差异为10.2%[95% CI,1.3-19.7])。pembro gp未达到中位EFS(95%CI:28.2-NR),pbo gp未达到30.9个月(22.8-NR)(HR 0.79;95%CI:0.52-1.22)。24个月的EFS率分别为66%和57%。两组均未达到中位OS(HR 1.04;95%CI:0.66-1.66)。24个月的OS率分别为72%和73%。Pembro gp与pbo gp在所有阶段的≥3级药物相关AE的发生率分别为76%和63%,严重药物相关AE分别为42%和20%,手术相关AE分别为20%和13%。pembro gp和pbo gp分别有3例(3%)和1例(1%)患者因药物相关AE而死亡。
结论
新辅助/辅助pembro+FLOT是可行的,暂时没有新的安全问题。在未经治疗的局部晚期可切除的G/GEJ癌患者中,接受pbo+FLOT治疗的患者相比接受pbo+FLOT治疗的患者在PathCR和EFS上获益更多。

SKYSCRAPER-08: A phase III, randomized, double-blind, placebo-controlled study of first-line (1L) tiragolumab (tira) + atezolizumab (atezo) and chemotherapy (CT) in patients (pts) with esophageal squamous cell carcinoma (ESCC).
Abstract:245
Background:
Inhibition of TIGIT, a novel checkpoint inhibitor, may further amplify immune responses by complementing the PD-L1/PD-1 pathway. Anti-tumor activity has been demonstrated with cancer immunotherapy in ESCC. SKYSCRAPER-08 (NCT04540211) is evaluating the efficacy and safety of tira (anti-TIGIT) + atezo (anti-PD-L1) in combination with CT compared with placebo + CT as 1L treatment (tx) in an Asian population with unresectable locally advanced (LA), unresectable recurrent, or metastatic (R/M) ESCC.
Methods:
Eligible pts (confirmed LA or R/M ESCC; ECOG PS 01; no prior systemic tx) were randomized 1:1 to receive tira 600mg + atezo 1200mg + CT (paclitaxel 175mg/m2 + cisplatin 6080mg/m2, local standard of care) or placebo + CT on Day 1 of each 21-day cycle (cycles 16); followed by tira + atezo or placebo maintenance until loss of clinical benefit/unacceptable toxicity. Primary endpoints: independent review facility (IRF)-assessed progression-free survival (PFS) and overall survival (OS). Secondary endpoints: investigator (INV)-assessed PFS, objective response rate (ORR), duration of response (DoR), and safety.
Results:
Overall, 461 pts were randomized (tira + atezo + CT, n= 229; placebo + CT, n=232). Pt characteristics were generally balanced between arms. As of 15 June 2022 (minimum survival follow-up 6.5 months [mo]; PFS primary analysis), median IRFassessed PFS was 6.2 mo for tira + atezo + CT vs 5.4 mo for placebo + CT (HR 0.56; 95% CI: 0.45, 0.70; P,0.0001). As of 13 Feb 2023 (minimum survival follow-up 14.5 mo; OS final analysis), median OS was 15.7 mo for tira + atezo + CT vs 11.1 mo for placebo + CT (HR: 0.70; 95% CI: 0.55, 0.88; P= 0.0024). INV-assessed PFS, IRF-assessed ORR and DoR are presented in Table. Treatment-related adverse events (TRAEs) occurred in 98.2% of pts (both arms); Grade 3/4 TRAEs in 59.6% (tira + atezo + CT) and 56.4% (placebo + CT) of pts; Grade 5 TRAEs in 2.6% (tira + atezo + CT) and 0.9% (placebo + CT) of pts.
Conclusions:
The study met both primary endpoints of IRF-assessed PFS and OS, demonstrating statistically significant and clinically meaningful improvements in PFS and OS for tira + atezo + CT over placebo + CT. Generally consistent benefit was observed across subgroups, including PD-L1 status. The safety profile was consistent with the known risks of the individual tx. Clinical trial information: NCT04540211.
Pembrolizumab plus FLOT vs FLOT as neoadjuvant and adjuvant therapy in locally advanced gastric and gastroesophageal junction cancer: Interim analysis of the phase 3 KEYNOTE-585 study
Abstract:247
Background:
The phase 3 KEYNOTE-585 study (NCT03221426) evaluated neoadjuvant/adjuvant pembrolizumab (pembro) or placebo (pbo) + chemotherapy (chemo) followed by adjuvant pembro vs pbo in locally advanced, resectable gastric or gastroesophageal junction (G/GEJ) cancer. A separate cohort evaluated pembro + FLOT (FLOT cohort). We report results from safety and efficacy analyses of the FLOT cohort at third interim analysis.
Methods:
In the FLOT cohort, patients (pts) with untreated, locally advanced, resectable G/GEJ cancer were randomized 1:1 to neoadjuvant pembro 200 mg IV Q3W (pembro gp) or pbo (pbo gp) Q3W for 3 cycles + FLOT (docetaxel, oxaliplatin, leucovorin, and 5-FU) Q2W for 4 cycles. After surgery, pts received adjuvant pembro or pbo Q3W for 3 cycles + FLOT Q2W for 4 cycles, then adjuvant pembro or pbo Q3W for 11 cycles. Endpoints evaluated included safety, pathCR rate (BICR), EFS (RECIST 1.1, by investigator), and OS in the ITT. Data cut-off at third interim analysis was 09 Feb 2023.
Results:
A total of 203 pts were randomized (100 pembro + FLOT; 103 pbo + FLOT). Among these, 12 (6%) pts had cT1-T2, 161 (79%) had cT3, and 9 (4%) had cT4. 140 (69%) had N+ disease, and 79 (39%) had GEJ adenocarcinoma at baseline. Median follow-up was 31.6 months (mo) and 31.1 mo, respectively, at IA3. A total of 94 of 99 (95%) pts completed the neoadjuvant phase, 87 of 99 (87%) completed the surgery phase, and 45 of 77 (58%) completed adjuvant treatment. The R0-resection rate was 79% vs 80% in the pembro gp vs pbo gp, respectively.
The pathCR rate was 17.0% (95% CI, 10.2-25.8) in the pembro gp and 6.8% (95% CI, 2.8-13.5) in the pbo gp, estimated difference (10.2% [95% CI, 1.3-19.7]). Median EFS was not reached (95% CI, 28.2-NR) in the pembro gp and 30.9 mo (22.8-NR) in the pbo gp (HR 0.79; 95% CI, 0.52-1.22). The 24-mo EFS rates were 66% and 57%, respectively. Median OS was not reached in either group (HR 1.04; 95% CI, 0.66-1.66). The 24-mo OS rates were 72% and 73%, respectively. Grade $ 3 drug-related AE rates in all phases combined were 76% and 63% in the pembro vs pbo gp, with serious drug-related AEs in 42% vs 20%, and surgery-related AEs in 20% vs 13%, respectively. A total of 3 (3%) vs 1 (1%) pt in the pembro vs pbo gp died due to a drug-related AE.
Conclusions:
Neoadjuvant/adjuvant pembro + FLOT was feasible with no new safety concerns.
PathCR and EFS favored pembro + FLOT vs pbo + FLOT in pts with untreated, locally advanced resectable G/GEJ cancer. Clinical trial information: NCT03221426.

Results:
A total of 203 pts were randomized (100 pembro + FLOT; 103 pbo + FLOT). Among these, 12 (6%) pts had cT1-T2, 161 (79%) had cT3, and 9 (4%) had cT4. 140 (69%) had N+ disease, and 79 (39%) had GEJ adenocarcinoma at baseline.

A total of 3 (3%) vs 1 (1%) pt in the pembro vs pbo gp died due to a drug-related AE.
