Summary

Background

Surufatinib showed superior efficacy in extrapancreatic neuroendocrine tumours (NETs) in the phase 3 SANET-ep study. In SANET-p, we aimed to assess the efficacy and safety of surufatinib in patients with advanced pancreatic NETs.

Methods

SANET-p was a multicentre, randomised, double-blind, placebo-controlled, phase 3 study, done in 21 hospitals across China. Eligible patients were adults (aged 18 years or older) with progressive, advanced, well differentiated pancreatic NETs, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and progression on up to two kinds of previous systemic regimens for advanced disease. Patients were randomly assigned (2:1) via an interactive web response system to receive 300 mg of surufatinib or placebo, taken orally once per day in consecutive 4-week treatment cycles until disease progression, intolerable toxicity, withdrawal of consent, poor compliance, use of other antitumour medication, pregnancy, loss to follow-up, or if the investigator deemed discontinuation in the patient’s best interest. Randomisation was done centrally using stratified block randomisation (block size three), stratified by pathological grade, previous systemic antitumour treatment, and ECOG performance status score. Patients, investigators, research staff, and the sponsor study team were masked to treatment allocation. Crossover to surufatinib was permitted for patients in the placebo group with disease progression. The primary endpoint was investigator-assessed progression-free survival in the intention-to-treat population, which included all patients in randomisation. A pre-planned interim analysis was done at 70% of the predicted progression-free survival events. This study is registered at ClinicalTrials.govNCT02589821.

Findings

Between Feb 18, 2016, and Nov 11, 2019, of 264 patients who were screened, 172 (65%) patients were randomly assigned to receive surufatinib (n=113) or placebo (n=59). The median follow-up was 19·3 months (95% CI 9·3–19·4) in the surufatinib group and 11·1 months (5·7–35·9) in the placebo group. The median investigator-assessed progression-free survival was 10·9 months (7·5–13·8) for surufatinib versus 3·7 months (2·8–5·6) for placebo (hazard ratio 0·49, 95% CI 0·32–0·76; p=0·0011). The trial met the early stopping criteria at the interim analysis and was terminated on recommendation from the independent data monitoring committee. The most common grade 3 or worse treatment-related adverse events were hypertension (43 [38%] of 113 with surufatinib vs four [7%] of 59 with placebo), proteinuria (11 [10%] vs one [2%]), and hypertriglyceridaemia (eight [7%] vs none). Treatment-related serious adverse events were reported in 25 (22%) patients in the surufatinib group and four (7%) patients in the placebo group. There were three on-treatment deaths in the surufatinib group, including two deaths due to adverse events (gastrointestinal haemorrhage [possibly treatment-related] and cerebral haemorrhage [unlikely to be treatment-related]), and one death attributed to disease progression. One on-treatment death in the placebo group was attributed to disease progression.

Interpretation

Surufatinib significantly improves progression-free survival and has an acceptable safety profile in patients with progressive, advanced pancreatic NETs, and could be a potential treatment option in this patient population.

Summary

Background

Therapeutic options for advanced neuroendocrine tumours (NETs) are limited. We investigated the efficacy and safety of surufatinib (HMPL-012, sulfatinib) in patients with extrapancreatic NETs.

Methods

SANET-ep was a randomised, double-blind, placebo-controlled, phase 3 trial undertaken at 24 hospitals across China. Patients (aged 18 years or older) with unresectable or metastatic, well differentiated, extrapancreatic NETs, with an Eastern Cooperative Oncology Group performance status of 0 or 1, and progression on no more than two types of previous systemic regimens were enrolled. Patients were centrally randomly assigned (2:1) using stratified block randomisation (block size 3) via an interactive web response system to receive oral surufatinib at 300 mg per day or matching placebo. Randomisation was stratified by tumour origin, pathological grade, and previous treatment. Patients, investigators, research staff and the sponsor study team were masked to treatment allocation. Crossover to the surufatinib group was allowed for patients in the placebo group at disease progression. The primary endpoint was investigator-assessed progression-free survival, which was analysed in the intention-to-treat population. A preplanned interim analysis was done at 70% of predicted progression-free survival events. This study was registered with ClinicalTrials.govNCT02588170. Follow-up is ongoing.

Findings

Between Dec 9, 2015, and March 31, 2019, 198 patients were randomly assigned to surufatinib (n=129) or placebo (n=69). Median follow-up was 13·8 months (95% CI 11·1–16·7) in the surufatinib group and 16·6 months (9·2–not calculable) in the placebo group. Investigator-assessed median progression-free survival was 9·2 months (95% CI 7·4–11·1) in the surufatinib group versus 3·8 months (3·7–5·7) in the placebo group (hazard ratio 0·33; 95% CI 0·22–0·50; p<0·0001). As the trial met the predefined criteria for early discontinuation of the study at the interim analysis, the study was terminated early, as recommended by the independent data monitoring committee. The most common treatment-related adverse events of grade 3 or worse were hypertension (47 [36%] of 129 patients in the surufatinib group vs nine [13%] of 68 patients in the placebo group) and proteinuria (25 [19%] vs zero). Treatment-related serious adverse events were reported in 32 (25%) of 129 patients in the surufatinib group and nine (13%) of 68 patients in the placebo group. Treatment-related deaths occurred in three patients in the surufatinib group (disseminated intravascular coagulation and hepatic encephalopathy, liver injury, and death with unknown reason) and one patient in the placebo group (cachexia and respiratory failure).

Interpretation

Progression-free survival was significantly longer in patients given surufatinib compared with patients given placebo, and surufatinib has a favourable benefit-to-risk profile in patients with progressive, advanced, well differentiated extrapancreatic NETs. Our results suggest that surufatinib might be a new treatment option for this population.

Background

Surufatinib, a kinase inhibitor targeting vascular endothelial growth factor receptors, fibroblast growth factor receptor 1 and colony stimulating factor-1 receptor, has demonstrated superior efficacy in extra-pancreatic neuroendocrine tumors (NETs) in a prior phase III study (ESMO 2019 Abs. LBA76). Here we report results from a parallel study of surufatinib in pancreatic NETs (pNETs).

 

Methods

The study evaluated the efficacy and safety of S in Pts with well-differentiated (pathological grade 1 or 2), progressive, unresectable or metastatic pNETs. Pts were randomized in a 2:1 ratio to receive S or P, 300 mg, orally, once daily, until disease progression or intolerable adverse events. Crossover at disease progression was allowed. The primary endpoint was investigator-assessed progression-free survival (PFS).

 

Results

By the cutoff date on 11 November 2019 for the pre-planned interim analysis, 172 Pts were randomized, 113 pts to S and 59 to P. Baseline characteristics were well balanced. The study met the primary endpoint; investigator-assessed median PFS was 10.9 vs. 3.7 months in S and P arms, respectively, with hazard ratio (HR)=0.491; 95% confidence interval [CI]: 0.319–0.755; p=0.0011. Analysis by a blinded independent radiology committee confirmed PFS improvement (13.9 vs. 4.6 months; HR=0.339; 95% CI: 0.209–0.549; p<0.0001). The investigator-assessed objective response rate was 19.2% with S and 1.9% with P (p=0.0021). Most common (≥5% in either arm) grade ≥3 treatment-emergent adverse events (TEAEs) were hypertension (38.9% in S arm vs. 8.5% in P arm), proteinuria (9.7% vs. 1.7%), hypertriglyceridaemia (7.1% vs. 0), alanine aminotransferase increased and gamma-glutamyltransferase increased (both 2.7% vs. 5.1%). TEAEs leading to drug discontinuation occurred in 10.6% pts vs. 6.8% pts in S and P arm respectively.

 

Conclusions

Surufatinib significantly improved the PFS in Pts with progressive, well-differentiated advanced pNETs. The safety profile was manageable and consistent with observations in prior studies. Surufatinib represents a promising treatment option in the armamentarium against pNETs.

中国香港、上海和美国新泽西州:2020920日,星期和黄中国医药科技有限公司(简称“和黄医药”或“Chi-Med”)(纳斯达克/伦敦证交所: HCM)今日于2020年欧洲肿瘤内科学会(“ESMO”)线上年会上以口头报告的形式公布了索凡替尼治疗晚期胰腺神经内分泌瘤患者的III期临床试验SANET-p的积极结果(摘要编号1156O)。SANET-p研究结果,以及早前已公布的索凡替尼治疗晚期非胰腺神经内分泌瘤的III期临床试验SANET-ep的结果今天于《柳叶刀·肿瘤学》上同步发表。

SANET-p研究的主要研究者,中国人民解放军总医院第五医学中心消化肿瘤科主任徐建明教授表示:“索凡替尼在晚期胰腺神经内分泌瘤患者中展现的益处具有重要的统计学及临床意义。此项研究结果,加上索凡替尼于非胰腺神经内分泌瘤患者中平行研究取得的积极结果,共同支持了索凡替尼成为所有肿瘤来源的高分化神经内分泌瘤患者中具有潜力的治疗选择。”

2020年1月,SANET-p研究的独立数据监察委员会(“IDMC”)于预设的中期分析中评估研究已经成功达到无进展生存期(“PFS”)这一预设的主要终点,并建议提前终止研究。截至2019 年11 月11 日的数据截止日,共有172名患者被随机分组(2:1)至接受300 mg 索凡替尼每日一次口服治疗(N=113)或安慰剂对照治疗(N=59),28 天为一个治疗周期。 根据研究者评估,索凡替尼治疗组患者的中位PFS 为10.9个月,与之相比,安慰剂组患者则为3.7个月(风险比 [HR] 0.491;95% 置信区间 [CI] 0.391 – 0.755;p = 0.0011)。在大部分主要的胰腺神经内分泌瘤患者亚组中均观察到了治疗疗效。 索凡替尼组104例疗效可评估的患者中,客观缓解率(ORR)为19.2%[1],而安慰剂组53例疗效可评估的患者中仅为1.9%[2],疾病控制率(DCR)分别为80.8%和66.0%。 该研究中大多数患者分级属2级,并伴随沉重的肿瘤负荷,包括肝转移和多器官受累。治疗疗效亦得到了盲态独立影像学审查委员会(BIIRC)的支持,索凡替尼组的中位PFS为13.9个月,而安慰剂组则为4.6个月(HR 0.339;95% CI 0.209 – 0.549;p <0.0001)。

索凡替尼具有可控的安全性特征,并且与既往研究中的观察结果一致。 大多数患者均对索凡替尼治疗的耐受性良好,索凡替尼组中因治疗后出现的不良事件导致的停药比率为10.6%,安慰剂组为6.8%。

美国食品药品监督管理局(“FDA”)授予索凡替尼两项“快速通道”资格,用于治疗胰腺和非胰腺神经内分泌瘤。索凡替尼同时获FDA授予 “孤儿药”资格认证,用于治疗胰腺神经内分泌瘤。基于这两项研究以及正在进行中的美国多列队Ib期研究的强有力数据支持,我们计划向FDA滚动递交新药上市申请(NDA),并于其后向欧洲药品管理局(EMA)提交欧洲上市许可申请(MAA)。索凡替尼用于治疗晚期非胰腺神经内分泌瘤的新药上市申请已于2019年12月获中国国家药品监督管理局(“国家药监局”)纳入优先审评。索凡替尼用于治疗晚期胰腺神经内分泌瘤的第二项新药上市申请已获国家药监局受理。

 

关于神经内分泌瘤

神经内分泌瘤起源于与神经系统相互作用的细胞或产生激素的腺体。神经内分泌瘤可起源于体内很多部位,最常见于消化道或肺部,可为良性或恶性肿瘤。神经内分泌瘤通常分为胰腺神经内分泌瘤和非胰腺神经内分泌瘤。获批的靶向治疗包括索坦®(苹果酸舒尼替尼)和飞尼妥®(依维莫司),用于治疗胰腺神经内分泌瘤或高度分化的非功能性胃肠道或肺神经内分泌瘤。

据Frost & Sullivan公司估计,2018年美国神经内分泌瘤新诊断病例为19,000例。值得关注的是,与其他肿瘤相比,神经内分泌瘤患者的生存期相对较长。因此,据估计2018年美国神经内分泌瘤患者约141,000名。

在中国,2018年约有67,600例神经内分泌瘤新诊断病例。按照中国的发病率与流行率比例(incidence to prevalence ratio)估算,中国总共或有高达300,000名神经内分泌瘤患者。[3]

 

关于索凡替尼

索凡替尼(surufatinib)是一种新型的口服酪氨酸激酶抑制剂,具有抗血管生成和免疫调节双重活性。索凡替尼可通过抑制血管内皮生长因子受体(VEGFR)和成纤维细胞生长因子受体(FGFR)以阻断肿瘤血管生成,并可抑制集落刺激因子1受体(CSF-1R),通过调节肿瘤相关巨噬细胞,促进机体对肿瘤细胞的免疫应答。索凡替尼独特的双重机制能产生协同抗肿瘤活性,使其为与其他免疫疗法的联合使用的理想选择。

和黄医药目前拥有索凡替尼在全球范围内的所有权利。

 

索凡替尼开发计划

美国与欧洲神经内分泌瘤研究:在美国,索凡替尼于2020年4月被授予快速通道资格,用于治疗胰腺和非胰腺神经内分泌瘤,并于2019年11月被授予“孤儿药”资格认证,用于治疗胰腺神经内分泌瘤 。美国新药上市申请正在准备中,并其后将向欧洲药品管理局提交欧洲上市许可申请。以上申请均是基于已完成的SANET-ep和SANET-p研究,以及索凡替尼在美国治疗非胰腺和胰腺神经内分泌瘤患者的现有数据(clinicaltrials.gov 注册号NCT02549937)。

中国非胰腺神经内分泌瘤研究:2019年11月,国家药监局受理了索凡替尼用于治疗非胰腺神经内分泌瘤新药上市申请,并于2019年12月纳入优先审评。该新药上市申请获成功的SANET-ep研究数据支持。SANET-ep是一项关于索凡替尼治疗晚期非胰腺神经内分泌瘤患者的中国III期临床试验,而这些患者目前尚无有效治疗方法。2019年6月,该研究IDMC评估认为,共198名患者参与的中期分析成功达到PFS这一预设主要疗效终点并提前终止研究。该项研究的积极结果于2019年ESMO年会上以口头报告的形式公布(clinicaltrials.gov 注册号NCT02588170),并于2020年9月在《柳叶刀·肿瘤学》上发表。[4]索凡替尼治疗组患者的中位PFS 为9.2个月,与之相比,安慰剂组患者则为3.8个月(HR 0.334;95% CI 0.223 – 0.499;p <0.0001)。

中国胰腺神经内分泌瘤研究:2016年,和黄医药在中国启动了一项关键性III期注册研究SANET-p,入组患者为低级别或中级别晚期胰腺神经内分泌瘤患者。2020年1月,该研究IDMC评估中期分析已经成功达到PFS这一预设主要疗效终点并建议提前终止研究(clinicaltrials.gov 注册号NCT02589821),国家药监局已受理索凡替尼的第二项新药上市申请。该项研究的结果已于2020年ESMO线上年会上公布,并同步发表于《柳叶刀·肿瘤学》。[5]

中国胆道癌研究:2019年3月,和黄医药启动了一项IIb/III期临床试验,旨在对比索凡替尼和卡培他滨治疗一线化疗失败晚期胆道癌患者的疗效和安全性。该研究的主要终点为总生存期(OS)(clinicaltrials.gov 注册号:NCT03873532)。

免疫联合疗法:我们达成了数个合作协议,以评估索凡替尼与PD-1单克隆抗体联合疗法的安全性、耐受性和疗效,包括已于中国获批的替雷利珠单抗(BGB-A317, 由百济神州有限公司开发)、拓益®(特瑞普利单抗, 由上海君实生物医药科技股份有限公司开发)和达伯舒®(信迪利单抗, 由信达生物制药(苏州)有限公司开发)。

Background

Fru is a highly selective, novel vascular endothelial growth factor receptor (VEGFR) -1, -2, and -3 tyrosine kinase inhibitor (TKI). In the ph 3 FRESCO study (NCT02314819) that led to its approval in China, Fru 5mg daily, 3 weeks (wks) on 1 wk off, improved the median overall survival in pts with mCRC in third line and beyond when compared to placebo (9.3 v 6.6 months); hazard ratio 0.65 (P < 0.001).

Methods

This is an ongoing ph 1/1b open-label, dose escalation (esc)/exp study conducted in the US. The dose esc was previously reported with confirmation of the approved dose/schedule in China. Here we present the preliminary safety and efficacy data from pts with refractory mCRC (exp) who progressed on all standard therapies including TAS-102 and/or regorafenib (rego).

Results

To date, 24 pts have been treated; age <65 years (62.5%), Caucasian (75%), female (54.2%), and ECOG PS 1 (62.5%). Median number of prior therapies was 4 (range: 1-7), and 7 pts (29.2%) received rego, 11 (45.8%) received TAS-102 and 6 (25.0%) received both rego and TAS-102. 16 pts remain on treatment. The median duration of Fru treatment was 2.8 months (range: 0.7– 10.4). The most frequently reported treatment-related (TR) treatment emergent adverse events (TEAEs) of any grade (Gr)(≥20% of pts) were hypertension (37.5%), proteinuria (29.2%), fatigue (29.2%), hand-foot syndrome (HFS)(29.2%), diarrhea (25.0%), headache (20.8%), stomatitis (20.8%), and elevated alk phos (20.8%). 8 (33.3%) pts reported Gr ≥3 TR TEAEs. Those that occurred in ≥5% of pts were hypertension (25%), proteinuria (8.3%) and fatigue (8.3%). No Gr ≥3 HFS was seen. Preliminary efficacy in pts who had a post-baseline scan and at least 3 months of follow up or discontinued treatment early (n=14) showed stable disease in 11 pts, with a disease control rate of 78.6%.

Conclusions

Fru is generally well-tolerated in heavily pretreated pts with refractory mCRC, with less HFS compared to other VEGFR TKIs. Evidence of anticancer activity was also observed in these pts. The multi-cohort dose exp is ongoing. Fru is being further investigated in refractory mCRC in a global Ph 3 study (NCT04322539).

Background

Surufatinib, a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptors (1,2,3), fibroblast growth factor receptor 1 and colony stimulating factor 1 receptor, has demonstrated superior efficacy in extrapancreatic neuroendocrine tumors (NETs) in a phase III study (SANET-ep, ESMO 2019 Abs. LBA76). The proliferation marker Ki-67 and primary tumor origins are the major prognostic factors in NETs.

Methods

The post-hoc efficacy analysis of surufatinib versus placebo was conducted by Ki-67 subcategory (<3%, 3-10%, >10%) and primary tumor origins (foregut, midgut, hindgut, others or unknown) in patients (pts) with advanced well-differentiated (grade 1 or 2) extrapancreatic NETs. The primary endpoint (progression-free survival [PFS]) and secondary endpoint (objective response rate [ORR]) both by investigator assessment (RECIST1.1) were analyzed.

Results

Median PFS was significantly prolonged with surufatinib compared to placebo in subgroups of Ki-67 3-10% (7.6 vs 4.6 months [mo], hazard ratio [HR] 0.47, P=0.0012), Ki-67 >10% (8.3 vs 2.1 mo, HR 0.14, P<0.0001), foregut (8.4 vs 4.6 mo, HR 0.29, P=0.0001) and hindgut (8.3 vs 2.1 mo, HR 0.35, P=0.0014). There was numerical PFS improvement with surufatinib compared to placebo in the rest subgroups: Ki 67 <3% (13.9 vs 7.4 mo, HR 0.43, P=0.0557), midgut (19.2 vs 8.9 mo, HR not analyzed due to small sample size) and unknown origin (9.2 vs 5.5 mo, HR 0.56, P=0.2943). ORR in the subgroups of Ki-67 <3%, 3-10%, >10% with surufatinib were 4.8%, 7.7%% and 20.0% respectively. There was no objective response in the placebo arm. ORR in the subgroups of foregut, midgut and unknown origin with surufatinib was 18.4%, 16.7% and 10.0% respectively while no response was observed in subgroups of hindgut or other origins.

Conclusions

Surufatinib demonstrated clinically significant benefits for pts with advanced well-differentiated extrapancreatic NETs compared to placebo. Results of this exploratory analysis were consistent with those reported for the SANET-ep primary analysis, and improved outcomes were observed across major subgroups.

中国香港、上海和美国新泽西州2020917日,星期四:和黄中国医药科技有限公司(简称“和黄医药”或“Chi-Med”)(纳斯达克/伦敦证交所: HCM)今日宣布,中国国家药品监督管理局(“国家药监局”)已受理索凡替尼(surufatinib)用于治疗晚期胰腺神经内分泌瘤的新药上市申请。

此次新药上市申请是基于成功的SANET-p临床研究数据。SANET-p是一项索凡替尼以晚期胰腺神经内分泌瘤为适应症的III 期关键性研究,而这些患者目前尚无有效的治疗方法。该研究于2020年1月完成中期分析并取得积极结果后提前终止。索凡替尼在该研究中改善了无进展生存期(“PFS”),此积极结果将在2020年欧洲肿瘤内科学会(“ESMO”)年会上发表(摘要编号1156O)。这是索凡替尼第二次获受理新药上市申请。此前,国家药监局于2019年11月受理了索凡替尼的首个新药上市申请用于治疗非胰腺神经内分泌瘤,并于2019年12月将该新药上市申请纳入优先审评。

和黄医药目前拥有索凡替尼在全球范围内的所有权利。索凡替尼正在中国和美国作为单药疗法或作为与免疫疗法的联合疗法,开展多种实体瘤研究。

2020年4月,美国食品药品监督管理局(FDA)对索凡替尼用于治疗非胰腺和胰腺神经内分泌瘤开发项目授予快速通道资格。和黄医药已启动美国新药上市申请的准备工作,并计划于2020年底开始滚动递交申请。此外,和黄医药计划于2021年递交欧洲上市许可申请。

 

关于神经内分泌瘤

神经内分泌瘤(NET)起源于与神经系统相互作用的细胞或产生激素的腺体。神经内分泌瘤可起源于体内很多部位,最常见于消化道或肺部,可为良性或恶性肿瘤。神经内分泌瘤通常分为胰腺神经内分泌瘤和非胰腺神经内分泌瘤。获批的靶向治疗包括索坦®(苹果酸舒尼替尼)和飞尼妥®(依维莫司),用于治疗胰腺神经内分泌瘤或高度分化的非功能性胃肠道或肺神经内分泌瘤。

据Frost & Sullivan公司估计,2018年美国神经内分泌瘤新诊断病例为19,000例。值得关注的是,与其他肿瘤相比,神经内分泌瘤患者的生存期相对较长。此外,据估计2018年美国神经内分泌瘤患者约141,000名。

在中国,2018年约有67,600例神经内分泌瘤新诊断病例。按照中国的发病率与流行率比例(incidence to prevalence ratio)估算,中国总共或有高达300,000名神经内分泌瘤患者。

 

关于索凡替尼

索凡替尼(surufatinib)是一种新型的口服酪氨酸激酶抑制剂,具有抗血管生成和免疫调节双重活性。索凡替尼可通过抑制血管内皮生长因子受体(VEGFR)和成纤维细胞生长因子受体(FGFR)以阻断肿瘤血管生成,并可抑制集落刺激因子1受体(CSF-1R),通过调节肿瘤相关巨噬细胞,促进机体对肿瘤细胞的免疫应答。索凡替尼独特的双重机制能产生协同抗肿瘤活性,使其为与其他免疫疗法的联合使用的理想选择。

和黄医药目前拥有索凡替尼在全球范围内的所有权利。

 

索凡替尼开发计划

中国非胰腺神经内分泌瘤研究:2019年11月,国家药监局受理了索凡替尼用于治疗非胰腺神经内分泌瘤新药上市申请,并于2019年12月纳入优先审评。该新药上市申请获成功的SANET-ep研究数据支持。SANET-ep是一项关于索凡替尼治疗晚期非胰腺神经内分泌瘤患者的中国III期临床试验,而这些患者目前尚无有效治疗方法。2019年6月,该研究独立数据监察委员会(“IDMC”)评估认为,共198名患者参与的中期分析成功达到无进展生存期(“PFS”)这一预设主要疗效终点并提前终止研究。该项研究的积极结果于2019年ESMO年会上以口头报告的形式公布(clinicaltrials.gov 注册号NCT02588170)。 

中国胰腺神经内分泌瘤研究:2016年,和黄医药在中国启动了一项关键性III期注册研究SANET-p,入组患者为低级别或中级别晚期胰腺神经内分泌瘤患者。2020年1月,该研究IDMC评估中期分析已经成功达到PFS这一预设主要疗效终点并建议提前终止研究(clinicaltrials.gov 注册号NCT02589821),国家药监局已受理索凡替尼的第二项新药上市申请。该项研究的结果将于2020年ESMO年会上公布。

中国胆道癌研究2019年3月,和黄医药启动了一项IIb/III期临床试验,旨在对比索凡替尼和卡培他滨治疗一线化疗失败晚期胆道癌患者的疗效和安全性。该研究的主要终点为总生存期(OS)(clinicaltrials.gov 注册号:NCT03873532)。

免疫联合疗法我们达成了数个合作协议,以评估索凡替尼与PD-1单克隆抗体联合疗法的安全性、耐受性和疗效,包括已于中国获批的替雷利珠单抗(BGB-A317, 由百济神州有限公司开发)、拓益®(特瑞普利单抗, 由上海君实生物医药科技股份有限公司开发)和达伯舒®(信迪利单抗, 由信达生物制药(苏州)有限公司开发)。

中国香港、上海和美国新泽西州:202094星期 和黄中国医药科技有限公司(简称“和黄医药”或“Chi-Med”)(纳斯达克/伦敦证交所:HCM)在美国、欧洲和日本启动了一项呋喹替尼治疗转移性结直肠癌患者的III期注册研究FRESCO-2。首名患者已于2020年9月3日在美国接受给药治疗。

FRESCO-2是一项在转移性结直肠癌患者中开展的随机、双盲、安慰剂对照的多中心临床试验。该研究的主要终点是总生存期(OS)。该项大型III期临床试验计划于10个国家的约130个研究中心开展患者招募。有关该研究的更多详情可登陆clinicaltrials.gov,检索注册号NCT04322539查看。

美国食品药品监督管理局(“FDA”)于2020年6月授予呋喹替尼快速通道资格,开发用于治疗转移性结直肠癌患者。根据我们与FDA达成的协议,呋喹替尼的临床数据(包括已在中国患者中完成的FRESCO III期研究,以及若取得积极结果的此项FRESCO-2研究),将可用于支持呋喹替尼用于治疗三线或以上转移性结直肠癌患者的新药上市申请(NDA)。FRESCO-2的研究设计亦已通过欧洲药品管理局(EMA)与日本医药品和医疗器械局(PMDA)的审阅及认可。

 

关于结直肠癌

结直肠癌是始于结肠或直肠的癌症,为全球第三大常见癌症,在2018年造成超过86万人死亡[1]。据估计,2020年美国预计新增15万人确诊结直肠癌以及5.3万例死亡[2]。在欧洲,结直肠癌是第二大常见癌症,2018年估计有49万例新增病例和24万例死亡[3]。在日本,结直肠癌是最常见的癌症,2018年估计有15万例新增病例和5.7万例死亡[4]

 

关于呋喹替尼

呋喹替尼是一种高选择性强效口服血管内皮生长因子受体(“VEGFR”)1、2及3的抑制剂。VEGFR抑制剂在限制肿瘤的血管生成中起到了至关重要的作用。呋喹替尼的独特设计使其激酶选择性更高,以达到更低的脱靶毒性、更高的耐受性及对靶点更稳定的覆盖。迄今,呋喹替尼在患者中的耐受性普遍良好,并且临床前研究中展示出的较低的药物间相互作用的可能性,或使其非常适合与其他癌症疗法联合使用。

和黄医药拥有呋喹替尼在中国以外区域的所有权利,并与礼来公司(“礼来”)在中国范围内合作。

 

呋喹替尼治疗转移性结直肠癌

呋喹替尼于2018年9月获中国国家药品监督管理局(国家药监局)批准在中国销售,并于2018年11月下旬由礼来以商品名爱优特®进行商业推广。爱优特®适用于既往接受过氟嘧啶、奥沙利铂和伊立替康治疗的转移性结直肠癌患者,包括既往接受过抗VEGF治疗和/或抗表皮生长因子受体(EGFR)治疗(RAS野生型)的患者。在中国416例转移性结直肠癌患者中开展的呋喹替尼III期关键性注册研究FRESCO的研究成果已于2018年6月在《美国医学会杂志》(JAMA)上发表(clinicaltrials.gov注册号:NCT02314819)。

2017年12月,和黄医药在美国启动了一项多中心开放标签的I/Ib期临床试验,旨在评估呋喹替尼在美国晚期实体瘤患者中的安全性、耐受性和药代动力学特性(clinicaltrials.gov 注册号:NCT03251378)。用于治疗转移性结直肠癌和转移性乳腺癌患者的概念验证试验于2019年开始。

 

呋喹替尼其他开发计划

中国胃癌研究:2017年10月,和黄医药启动了FRUTIGA研究。FRUTIGA研究是一项随机双盲III期临床试验,旨在评估呋喹替尼联合紫杉醇对比紫杉醇单药化疗治疗二线晚期胃癌或胃食管结合部(GEJ)腺癌的疗效和安全性。研究计划纳入对一线标准化疗无应答的患者。受试者将以1:1的比例随机分组,接受呋喹替尼联合紫杉醇或安慰剂联合紫杉醇治疗,并根据胃癌或胃食管结合部腺癌,和体能状态评分等因素进行分层。研究的主要疗效终点为总生存期(OS)。次要疗效终点包括无进展生存期(PFS,依据RECIST 1.1进行评估)、客观缓解率(ORR)、疾病控制率(DCR)、疾病缓解时间和生存质量评分(依据EORTC QLQ-C30,3.0版进行评估)。研究也将探索与呋喹替尼抗肿瘤活性相关的生物标志物(clinicaltrials.gov 注册号:NCT03223376)。2020年6月,和黄医药完成了一项预设的中期分析,基于预设标准,独立数据监察委员会(IDMC)建议研究继续进行。

免疫疗法联合用药:和黄医药已订立三项合作协议,以评估呋喹替尼与PD-1单克隆抗体联合疗法的安全性、耐受性和疗效,包括替雷利珠单抗(BGB-A317, 由百济神州有限公司开发)、达伯舒®(信迪利单抗,IBI308, 由信达生物制药(苏州)有限公司开发)和杰诺单抗(geptanolimab,GB226,由嘉和生物药业有限公司开发)。

中国香港、上海和美国新泽西州:202093星期四和黄中国医药科技有限公司(简称“和黄医药”或“Chi-Med”)(纳斯达克/伦敦证交所:HCM)启动了一项HMPL-453治疗晚期肝内胆管癌(IHCC)患者的II期临床试验,肝内胆管癌属于肝癌的一种。HMPL-453是一种靶向成纤维细胞生长因子受体(“FGFR”)的新型小分子抑制剂。

该研究是一项单臂、多中心、开放标签的临床试验,旨在评估HMPL-453治疗至少经过一线全身性治疗失败,并伴有FGFR2融合的晚期肝内胆管癌患者的疗效、安全性和药代动力学特性。

该研究的主要结果指标为客观缓解率(ORR)。次要结果评估包括初步疗效指标,例如疾病控制率(DCR)、到达疾病缓解的时间(TTR)、缓解持续时间(DoR)、无进展生存期(PFS)和总生存期(OS)。该项研究的其他详情可登录clinicaltrials.gov,检索 NCT04353375 查阅。

 

关于肝内胆管癌

肝内胆管癌是一种起源于胆管细胞的癌症[1]。中国每年新增肝癌病例超过39万例,占2018年全球新增肝癌病例的近半数[2],[3]。肝内胆管癌是仅次于肝细胞癌的第二常见的肝脏原发性恶性肿瘤,新诊断的肝癌中有10%至20%为肝内胆管癌[4]。肝内胆管癌患者中约有10-15%伴有FGFR2融合[5],[6]。肝内胆管癌患者的长期生存率较肝细胞癌患者低,这可能与较高的局部和远端转移倾向以及缺乏有效的全身性治疗选择有关[4]

 

关于成纤维细胞生长因子受体(FGFR)

FGFR是受体酪氨酸激酶的亚族之一。FGFR信号通路的激活是数个生物过程的关键。正常生理情况下,FGF/FGFR信号通路参与胚胎发育(器官发生和形态发生)、组织修复、血管生成、神经内分泌和代谢平衡。鉴于其在许多重要生理过程中的复杂性和关键作用,已发现异常的FGFR信号传导是肿瘤生长、促进血管生成以及抗肿瘤治疗抗性产生的诱因。

 

关于HMPL‑453

HMPL‑453是一种新型、强效且高选择性的小分子FGFR 1、2和3抑制剂。在临床前研究中, HMPL‑453较同类其他药物相比表现出更强的效力、更高的激酶选择性及更佳的安全性。在中国进行的HMPL-453 I期临床试验的剂量递增阶段已完成患者招募(clinicaltrials.gov 注册号NCT03160833)。在中国晚期恶性间皮瘤患者中进行的II期临床试验患者招募正在进行中(clinicaltrials.gov 注册号NCT04290325)。
