Immune checkpoint inhibitors or anti-claudin 18.2 antibodies? A network meta-analysis for the optimized first-line therapy of HER2-negative gastric cancer. (PubMed, Ther Adv Med Oncol)
For the overall survival (OS) analysis, no statistically significant differences were observed between pembrolizumab [hazard ratios (HR) = 1.00, 95% CI: 0.94-1.07], sintilimab (HR = 0.99, 95% CI: 0.89-1.09), sugemalimab (HR = 0.98, 95% CI: 0.87-1.10), tislelizumab (HR = 0.97, 95% CI: 0.87-1.09), zolbetuximab (HR = 0.98, 95% CI: 0.91-1.07), and nivolumab (HR = 1.00). In addition, anti-claudin-18.2-targeted therapies presented similar OS (HR = 0.99, 95% CI: 0.95-1.04) and PFS (HR = 1.01, 95% CI: 0.91-1.12) compared to immunotherapy, although their toxicity profiles were distinct. Our network meta-analysis showed no significant difference in PFS, OS, or ORR between different checkpoint inhibitors or between immunotherapy and anti-claudin-18.2-targeted therapies in the first-line treatment of HER2-negative, unresectable, or metastatic gastric cancers.

Advances and challenges of first-line immunotherapy for non-small cell lung cancer: A review. (PubMed, Medicine (Baltimore))
As a result of great achievements in clinical trials, 6 programmed death-1 inhibitors (sintilimab, camrelizumab, tislelizumab, pembrolizumab, cemiplimab, and nivolumab), 2 programmed death-ligand 1 inhibitors (sugemalimab and atezolizumab), and 1 cytotoxic T lymphocyte-associated antigen-4 inhibitor (ipilimumab) have been approved as first-line treatment for mNSCLC by the US Food and Drug Administration. Results from first-line trials have shown that almost all driver-negative mNSCLC are treated with ICIs and significantly prolong patient survival; however, the low response rate and adverse reactions to immunotherapy remain to be addressed. Here, we summarize the use of ICIs, including monotherapy and combination therapy, in the first-line treatment of mNSCLC in recent years and discuss the low response rate and adverse reactions of ICIs as well as the challenges and expectations for the first-line treatment of mNSCLC in the future.

Comparison of the profiles of first-line PD-1/PD-L1 inhibitors for advanced NSCLC lacking driver gene mutations: a systematic review and Bayesian network meta-analysis. (PubMed, Ther Adv Chronic Dis)
For the PD-L1 non-selective patients, sintilimab plus chemotherapy (sinti-chemo) provided the best OS [hazard ratio (HR) = 0.59, 95% confidence interval (CI):0.42-0.83]. Nivolumab plus bevacizumab plus chemotherapy (nivo-bev-chemo) was comparable to atezolizumab plus bevacizumab plus chemotherapy (atezo-bev-chemo) in prolonging PFS (HR = 0.99, 95% CI: 0.51-1.91)...Subgroup analysis showed pembrolizumab plus chemotherapy (pembro-chemo) ranked first in OS in subgroups of PD-L1 < 1%, non-squamous, no CNS metastases, with or without smoking history, and ranked second in OS in subgroups of PD-L1 ⩾ 1% and PD-L1 1-49%. Cemiplimab and sugemalimab plus chemotherapy ranked first in OS and PFS for squamous subgroup, respectively. For patients with CNS metastases, nivolumab plus ipilimumab plus chemotherapy (nivo-ipili-chemo) and camrelizumab plus chemotherapy provided the best OS and PFS, respectively...Addition of bevacizumab consistently provided with favorable PFS results in patients of all PD-L1 levels. Cemiplimab was the best option in squamous subgroup and nivo-ipili-chemo in CNS metastases subgroup due to their advantages in OS.

The Cost-Effectiveness of Sugemalimab Plus Chemotherapy as First-Line Treatment for Metastatic Squamous and Non-squamous NSCLC in China. (PubMed, Adv Ther)
Sugema + chemo was not cost-effective as a first-line treatment for either metastatic squamous or metastatic nonsquamous NSCLC in Chinese patients compared with placebo + chemo. However, we found that sugema + chemo would be cost-effective in patients with metastatic squamous and non-squamous NSCLC when sugemalimab's price was decreased by > 39.0% and 64.8%, respectively.

GEMSTONE-303: Prespecified progression-free survival (PFS) and overall survival (OS) final analyses of a phase III study of sugemalimab plus chemotherapy vs placebo plus chemotherapy in treatment-naïve advanced gastric or gastroesophageal junction (G/GEJ) adenocarcinoma (ESMO 2023)
Methods Eligible pts with previously untreated, no known HER2-positive status, PD-L1 expression ≥5%, unresectable advanced or metastatic G/GEJ adenocarcinoma were randomized 1:1 to receive suge/placebo (1200 mg, Q3W, IV) + CAPOX (capecitabine, 1000 mg/m2, PO, BID, D1-14, Q3W; oxaliplatin, 130 mg/m2, IV, Q3W; max 6 cycles). Table: LBA79 PD-L1 Expression Level >=5% Suge+CAPOX Placebo+CAPOX N=241 N=238 PFS (Months) Median (95% CI) 7.62 (6.37, 7.89) 6.08 (5.06, 6.44) P-value =10% N=130 N=128 PFS (Months) Median (95% CI) 7.79 (6.77, 9.99) 5.52 (4.83, 6.67) P-value 0.0001 HR (95% CI) 0.58 (0.43, 0.77) OS (Months) Median (95% CI) 17.81 (14.36, 21.16) 12.45 (9.89, 13.86) P-value 0.0022 HR (95% CI) 0.64 (0.48, 0.85) Conclusions Sugemalimab in combination with CAPOX demonstrates statistically significant and clinically meaningful improvements in PFS and OS, with a manageable safety profile. These findings support suge+CAPOX as new first-line treatment option for pts with PD-L1 expression ≥5%, advanced G/GEJ adenocarcinoma.

Interim survival analysis of the randomized phase III GEMSTONE-302 trial: sugemalimab or placebo plus chemotherapy as first-line treatment for metastatic NSCLC. (PubMed, Nat Cancer)
In this study, 479 treatment-naive patients with stage IV squamous or non-squamous NSCLC without known EGFR sensitizing mutations, ALK, ROS1 or RET fusions were randomized (2:1) to receive 1,200 mg of sugemalimab (n = 320) or placebo (n = 159) every 3 weeks in combination with platinum-based chemotherapy for up to four cycles, followed by maintenance therapy with sugemalimab or placebo for squamous NSCLC and sugemalimab or placebo plus pemetrexed for non-squamous NSCLC. As of 22 November 2021, the prespecified interim OS analysis showed significant improvement with the addition of sugemalimab to chemotherapy (median OS = 25.4 versus 16.9 months; hazard ratio = 0.65; 95% confidence interval = 0.50-0.84; P = 0.0008). Sugemalimab plus chemotherapy provided superior PFS and OS compared to placebo plus chemotherapy, supporting the use of sugemalimab as a first-line treatment option for metastatic NSCLC.

A trial-based cost-utility analysis of sugemalimab vs. placebo as consolidation therapy for unresectable stage III NSCLC in China. (PubMed, PLoS One)
From the perspective of Chinese healthcare system, sugemalimab consolidation therapy was not a cost-effective strategy in cCRT and sCRT patients with unresectable stage III NSCLC. Given that the sugemalimab PAP was available, sugemalimab consolidation therapy became a cost-effective option.

Sugemalimab: First Approval. (PubMed, Drugs)
In December 2021, sugemalimab was approved in China for the first-line treatment of epidermal growth factor receptor (EGFR) gene mutation and anaplastic lymphoma kinase (ALK) negative metastatic non-small cell lung cancer (NSCLC) administered in combination with pemetrexed and carboplatin for non-squamous NSCLC and in combination with paclitaxel and carboplatin for squamous NSCLC. Clinical studies assessing sugemalimab for the treatment of several other cancers, including liver cancer, gastric cancer, oesophageal cancer, Hodgkin lymphoma and extranodal natural killer/T cell lymphoma are underway in China, the US and Australia. This article summarizes the milestones in the development of sugemalimab leading to this first approval for the first-line treatment of EGFR gene mutation and ALK-negative metastatic NSCLC.

High efficacy of PD-1 inhibitor after initial failure of PD-L1 inhibitor in Relapsed/Refractory classical Hodgkin Lymphoma. (PubMed, BMC Cancer)
PD-L1 monotherapy may not be sufficient to block the PD-1 pathway; PD-L2 was expressed in HRS and background cells in cHL. The immunologic function of the PD-L2 pathway in anti-tumor activity may be underestimated in R/R cHL. Further study is needed to elucidate the anti-tumor mechanism of PD-1 inhibitor and PD-L1 inhibitor treatment.

[VIRTUAL] Platinum-based chemotherapy (chemo) with CS1001, an anti-PD-L1 antibody, for first-line advanced non-small cell lung cancer (NSCLC): Preliminary results from phase Ib cohorts of CS1001-101 study. (ASCO 2020)
Pts with non-squamous (nsq)-NSCLC received 4-6 cycles of CS1001 (1200 mg, IV, Q3W), carboplatin (AUC = 5), and pemetrexed (500 mg/m2), followed by maintenance therapy with CS1001 and pemetrexed. Pts with squamous (sq)-NSCLC received CS1001 (1200 mg, IV, Q3W), carboplatin (AUC = 5), and paclitaxel (175 mg/m2), followed by maintenance therapy with CS1001... The combination of CS1001 and platinum-based chemo regimen demonstrated promising anti-tumor activity with a tolerable safety profile. The results of this study support further evaluation of CS1001 and platinum-based chemo in 1L NSCLC. Currently, a randomized phase III study (NCT03789604) of this treatment regimen in pts with chemo-naive advanced NSCLC is recruiting pts in China.
