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.

中國香港、上海和美國新澤西州:2020920日,星期日:和黃中國醫藥科技有限公司(簡稱「和黃醫藥」或「Chi-Med」)(納斯達克/倫敦證交所: HCM)今日於2020年歐洲腫瘤內科學會(「ESMO」)網上年會上以口頭報告的形式公佈了索凡替尼治療晚期胰腺神經內分泌瘤患者的III期臨床試驗SANET-p的積極結果(摘要編號1156O)。SANET-p研究結果,以及早前已公佈的索凡替尼治療晚期非胰腺神經內分泌瘤的III期臨床試驗SANET-ep的結果今天於《刺針·腫瘤學》上同步發表。

SANET-p研究的主要研究者,中國人民解放軍總醫院第五醫學中心消化腫瘤科主任徐建明教授表示:「索凡替尼在晚期胰腺神經內分泌瘤患者中展現的益處具有重要的統計學及臨床意義。此項研究結果,加上索凡替尼於非胰腺神經內分泌瘤患者中平行研究取得的積極結果,共同支持了索凡替尼成為所有腫瘤來源的高分化神經內分泌瘤患者中具有潛力的治療選擇。」

2020年1月,SANET-p研究的獨立數據監察委員會(「IDMC」)於預設的中期分析中評估研究已經成功達到無進展生存期(「PFS」)這一預設的主要終點,並建議提前終止研究。截至2019 年11 月11 日的數據截止日,共有172名患者被隨機分組(2:1)至接受300 mg 索凡替尼每日一次口服治療(N=113)或安慰劑對照治療(N=59),28 天為一個治療週期。 根據研究者評估,索凡替尼治療組患者的中位PFS 為10.9個月,與之相比,安慰劑組患者則為3.7個月(風險比 [HR] 0.491;95% 置信區間 [CI] 0.391 – 0.755;p = 0.0011)。在大部分主要的胰腺神經內分泌瘤患者亞組中均觀察到了治療療效。 索凡替尼組104例療效可評估的患者中,客觀緩解率(ORR)為19.2%[1],而安慰劑組53例療效可評估的患者中僅為1.9%[2],疾病控制率(DCR)分別為80.8%和66.0%。 該研究中大多數患者分級屬2級,並伴隨沉重的腫瘤負荷,包括肝轉移和多器官受累。治療療效亦得到了盲態獨立影像學審查委員會(BIIRC)的支持,索凡替尼組的中位PFS為13.9個月,而安慰劑組則為4.6個月(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徵,並且與既往研究中的觀察結果一致。 大多數患者均對索凡替尼治療的耐受性良好,索凡替尼組中因治療後出現的不良事件導致的停藥比率為10.6%,安慰劑組為6.8%。

美國食品藥品監督管理局(「FDA」)授予索凡替尼兩項「快速通道」資格,用於治療胰腺和非胰腺神經內分泌瘤。索凡替尼同時獲FDA授予 「孤兒藥」資格認證,用於治療胰腺神經內分泌瘤。基於這兩項研究以及正在進行中的美國多列隊Ib期研究的強有力數據支持,我們計畫向FDA滾動遞交新藥上市申請(NDA),並於其後向歐洲藥品管理局(EMA)提交歐洲上市許可申請(MAA)。索凡替尼用於治療晚期非胰腺神經內分泌瘤的新藥上市申請已於2019年12月獲中國國家藥品監督管理局(「國家藥監局」)納入優先審評。索凡替尼用於治療晚期胰腺神經內分泌瘤的第二項新藥上市申請已獲國家藥監局受理。

 

關於神經內分泌瘤

神經內分泌瘤起源於與神經系統相互作用的細胞或產生激素的腺體。神經內分泌瘤可起源於體內很多部位,最常見於消化道或肺部,可為良性或惡性腫瘤。神經內分泌瘤通常分為胰腺神經內分泌瘤和非胰腺神經內分泌瘤。獲批的靶向治療包括索坦®(蘋果酸舒尼替尼)和飛尼妥®(依維莫司),用於治療胰腺神經內分泌瘤或高度分化的非功能性胃腸道或肺神經內分泌瘤。

據Frost & Sullivan公司估計,2018年美國神經內分泌瘤新診斷病例為19,000例。值得關注的是,與其他腫瘤相比,神經內分泌瘤患者的生存期相對較長。因此,據估計2018年美國神經內分泌瘤患者約141,000名。

在中國,2018年約有67,600例神經內分泌瘤新診斷病例。按照中國的發病率與流行率比例(incidence to prevalence ratio)估算,中國總共或有高達300,000名神經內分泌瘤患者。[3]

 

關於索凡替尼

索凡替尼(surufatinib)是一種新型的口服酪氨酸激酶抑制劑,具有抗血管生成和免疫調節雙重活性。索凡替尼可通過抑制血管內皮生長因子受體(VEGFR)和成纖維細胞生長因子受體(FGFR)以阻斷腫瘤血管生成,並可抑制集落刺激因子1受體(CSF-1R),通過調節腫瘤相關巨噬細胞,促進機體對腫瘤細胞的免疫應答。索凡替尼獨特的雙重機制能產生協同抗腫瘤活性,使其為與其他免疫療法的聯合使用的理想選擇。

和黃醫藥目前擁有索凡替尼在全球範圍內的所有權利。

 

索凡替尼開發計畫

美國與歐洲神經內分泌瘤研究:在美國,索凡替尼於2020年4月被授予快速通道資格,用於治療胰腺和非胰腺神經內分泌瘤,並於2019年11月被授予「孤兒藥」資格認證,用於治療胰腺神經內分泌瘤 。美國新藥上市申請正在準備中,並其後將向歐洲藥品管理局提交歐洲上市許可申請。以上申請均是基於已完成的SANET-ep和SANET-p研究,以及索凡替尼在美國治療非胰腺和胰腺神經內分泌瘤患者的現有數據(clinicaltrials.gov 註冊號NCT02549937)。

中國非胰腺神經內分泌瘤研究:2019年11月,國家藥監局受理了索凡替尼用於治療非胰腺神經內分泌瘤新藥上市申請,並於2019年12月納入優先審評。該新藥上市申請獲成功的SANET-ep研究數據支持。SANET-ep是一項關於索凡替尼治療晚期非胰腺神經內分泌瘤患者的中國III期臨床試驗,而這些患者目前尚無有效治療方法。2019年6月,該研究IDMC評估認為,共198名患者參與的中期分析成功達到PFS這一預設主要療效終點並提前終止研究。該項研究的積極結果於2019年ESMO年會上以口頭報告的形式公佈(clinicaltrials.gov 註冊號NCT02588170),並於2020年9月在《刺針·腫瘤學》上發表。[4]索凡替尼治療組患者的中位PFS 為9.2個月,與之相比,安慰劑組患者則為3.8個月(HR 0.334;95% CI 0.223 – 0.499;p <0.0001)。

中國胰腺神經內分泌瘤研究:2016年,和黃醫藥在中國啟動了一項關鍵性III期註冊研究SANET-p,入組患者為低級別或中級別晚期胰腺神經內分泌瘤患者。2020年1月,該研究IDMC評估中期分析已經成功達到PFS這一預設主要療效終點並建議提前終止研究(clinicaltrials.gov 註冊號NCT02589821),國家藥監局已受理索凡替尼的第二項新藥上市申請。該項研究的結果已於2020年ESMO網上年會上公佈,並同步發表於《刺針·腫瘤學》[5]

中國膽道癌研究:2019年3月,和黃醫藥啟動了一項IIb/III期臨床試驗,旨在對比索凡替尼和卡培他濱治療一線化療失敗晚期膽道癌患者的療效和安全性。該研究的主要終點為總生存期(OS)(clinicaltrials.gov 註冊號:NCT03873532)。

免疫聯合療法:我們達成了數個合作協議,以評估索凡替尼與PD-1單克隆抗體聯合療法的安全性、耐受性和療效,包括已於中國獲批的替雷利珠單抗(BGB-A317, 由百濟神州有限公司開發)、拓益®(特瑞普利單抗, 由上海君實生物醫藥科技股份有限公司開發)和達伯舒®(信迪利單抗, 由信達生物製藥(蘇州)有限公司開發)。

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.

中國香港、上海和美國新澤西州:2020917日,星期四:和黃中國醫藥科技有限公司(簡稱「和黃醫藥」或「Chi-Med」)(納斯達克/倫敦證交所: HCM)今日宣佈,中國國家藥品監督管理局(「國家藥監局」)已受理索凡替尼(surufatinib)用於治療晚期胰腺神經內分泌瘤的新藥上市申請。

此次新藥上市申請是基於成功的SANET-p臨床研究數據。SANET-p是一項索凡替尼以晚期胰腺神經內分泌瘤為適應症的III 期關鍵性研究,而這些患者目前尚無有效的治療方法。該研究於2020年1月完成中期分析並取得積極結果後提前終止。索凡替尼在該研究中改善了無進展生存期(「PFS」),此積極結果將在2020年歐洲腫瘤內科學會(「ESMO」)年會上發表(摘要編號1156O)。這是索凡替尼第二次獲受理新藥上市申請。此前,國家藥監局於2019年11月受理了索凡替尼的首個新藥上市申請用於治療非胰腺神經內分泌瘤,並於2019年12月將該新藥上市申請納入優先審評。

和黃醫藥目前擁有索凡替尼在全球範圍內的所有權利。索凡替尼正在中國和美國作為單藥療法或作為與免疫療法的聯合療法,開展多種實體瘤研究。

2020年4月,美國食品藥品監督管理局(FDA)對索凡替尼用於治療非胰腺和胰腺神經內分泌瘤開發項目授予快速通道資格。和黃醫藥已啟動美國新藥上市申請的準備工作,並計畫於2020年底開始滾動遞交申請。此外,和黃醫藥計畫於2021年遞交歐洲上市許可申請。

 

關於神經內分泌瘤

神經內分泌瘤(NET)起源於與神經系統相互作用的細胞或產生激素的腺體。神經內分泌瘤可起源於體內很多部位,最常見於消化道或肺部,可為良性或惡性腫瘤。神經內分泌瘤通常分為胰腺神經內分泌瘤和非胰腺神經內分泌瘤。獲批的靶向治療包括索坦®(蘋果酸舒尼替尼)和飛尼妥®(依維莫司),用於治療胰腺神經內分泌瘤或高度分化的非功能性胃腸道或肺神經內分泌瘤。

據Frost & Sullivan公司估計,2018年美國神經內分泌瘤新診斷病例為19,000例。值得關注的是,與其他腫瘤相比,神經內分泌瘤患者的生存期相對較長。此外,據估計2018年美國神經內分泌瘤患者約141,000名。

在中國,2018年約有67,600例神經內分泌瘤新診斷病例。按照中國的發病率與流行率比例(incidence to prevalence ratio)估算,中國總共或有高達300,000名神經內分泌瘤患者。

 

關於索凡替尼

索凡替尼(surufatinib)是一種新型的口服酪氨酸激酶抑制劑,具有抗血管生成和免疫調節雙重活性。索凡替尼可通過抑制血管內皮生長因子受體(VEGFR)和成纖維細胞生長因子受體(FGFR)以阻斷腫瘤血管生成,並可抑制集落刺激因子1受體(CSF-1R),通過調節腫瘤相關巨噬細胞,促進機體對腫瘤細胞的免疫應答。索凡替尼獨特的雙重機制能產生協同抗腫瘤活性,使其為與其他免疫療法的聯合使用的理想選擇。

和黃醫藥目前擁有索凡替尼在全球範圍內的所有權利。

 

索凡替尼開發計畫

中國非胰腺神經內分泌瘤研究:2019年11月,國家藥監局受理了索凡替尼用於治療非胰腺神經內分泌瘤新藥上市申請,並於2019年12月納入優先審評。該新藥上市申請獲成功的SANET-ep研究數據支持。SANET-ep是一項關於索凡替尼治療晚期非胰腺神經內分泌瘤患者的中國III期臨床試驗,而這些患者目前尚無有效治療方法。2019年6月,該研究獨立數據監察委員會(「IDMC」)評估認為,共198名患者參與的中期分析成功達到無進展生存期(「PFS」)這一預設主要療效終點並提前終止研究。該項研究的積極結果於2019年ESMO年會上以口頭報告的形式公佈(clinicaltrials.gov 註冊號NCT02588170)。 

中國胰腺神經內分泌瘤研究:2016年,和黃醫藥在中國啟動了一項關鍵性III期註冊研究SANET-p,入組患者為低級別或中級別晚期胰腺神經內分泌瘤患者。2020年1月,該研究IDMC評估中期分析已經成功達到PFS這一預設主要療效終點並建議提前終止研究(clinicaltrials.gov 註冊號NCT02589821),國家藥監局已受理索凡替尼的第二項新藥上市申請。該項研究的結果將於2020年ESMO年會上公佈。

中國膽道癌研究:2019年3月,和黃醫藥啟動了一項IIb/III期臨床試驗,旨在對比索凡替尼和卡培他濱治療一線化療失敗晚期膽道癌患者的療效和安全性。該研究的主要終點為總生存期(OS)(clinicaltrials.gov 註冊號:NCT03873532)。

免疫聯合療法:我們達成了數個合作協議,以評估索凡替尼與PD-1單克隆抗體聯合療法的安全性、耐受性和療效,包括已於中國獲批的替雷利珠單抗(BGB-A317, 由百濟神州有限公司開發)、拓益®(特瑞普利單抗, 由上海君實生物醫藥科技股份有限公司開發)和達伯舒®(信迪利單抗, 由信達生物製藥(蘇州)有限公司開發)。

中國香港、上海和美國新澤西州:202094星期 和黃中國醫藥科技有限公司(簡稱「和黃醫藥」或「Chi-Med」)(納斯達克/倫敦證交所:HCM)在美國、歐洲和日本啟動了一項呋喹替尼治療轉移性結直腸癌患者的III期註冊研究FRESCO-2。首名患者已於2020年9月3日在美國接受給藥治療。

FRESCO-2是一項在轉移性結直腸癌患者中開展的隨機、雙盲、安慰劑對照的多中心臨床試驗。該研究的主要終點是總生存期(OS)。該項大型III期臨床試驗計畫於10個國家的約130個研究中心開展患者招募。有關該研究的更多詳情可登陸clinicaltrials.gov,檢索註冊號NCT04322539查看。

美國食品藥品監督管理局(「FDA」)於2020年6月授予呋喹替尼快速通道資格,開發用於治療轉移性結直腸癌患者。根據我們與FDA達成的協議,呋喹替尼的臨床數據(包括已在中國患者中完成的FRESCO III期研究,以及若取得積極結果的此項FRESCO-2研究),將可用於支持呋喹替尼用於治療三線或以上轉移性結直腸癌患者的新藥上市申請(NDA)。FRESCO-2的研究設計亦已通過歐洲藥品管理局(EMA)與日本醫藥品和醫療器械局(PMDA)的審閱及認可。

 

關於結直腸癌

結直腸癌是始於結腸或直腸的癌症,為全球第三大常見癌症,在2018年造成超過86萬人死亡[1]。據估計,2020年美國預計新增15萬人確診結直腸癌以及5.3萬例死亡[2]。在歐洲,結直腸癌是第二大常見癌症,2018年估計有49萬例新增病例和24萬例死亡[3]。在日本,結直腸癌是最常見的癌症,2018年估計有15萬例新增病例和5.7萬例死亡[4]

 

關於呋喹替尼

呋喹替尼是一種高選擇性強效口服血管內皮生長因子受體(「VEGFR」)1、2及3的抑制劑。VEGFR抑制劑在限制腫瘤的血管生成中起到了至關重要的作用。呋喹替尼的獨特設計使其激酶選擇性更高,以達到更低的脫靶毒性、更高的耐受性及對靶點更穩定的覆蓋。迄今,呋喹替尼在患者中的耐受性普遍良好,並且臨床前研究中展示出的較低的藥物間相互作用的可能性,或使其非常適合與其他癌症療法聯合使用。

和黃醫藥擁有呋喹替尼在中國以外區域的所有權利,並與禮來公司(「禮來」)在中國範圍內合作。

 

呋喹替尼治療轉移性結直腸癌

呋喹替尼於2018年9月獲中國國家藥品監督管理局(國家藥監局)批准在中國銷售,並於2018年11月下旬由禮來以商品名愛優特®進行商業推廣。愛優特®適用於既往接受過氟嘧啶、奧沙利鉑和伊立替康治療的轉移性結直腸癌患者,包括既往接受過抗VEGF治療和/或抗表皮生長因子受體(EGFR)治療(RAS野生型)的患者。在中國416例轉移性結直腸癌患者中開展的呋喹替尼III期關鍵性註冊研究FRESCO的研究成果已於2018年6月在《美國醫學會雜誌》(JAMA)上發表(clinicaltrials.gov註冊號:NCT02314819)。

2017年12月,和黃醫藥在美國啟動了一項多中心開放標籤的I/Ib期臨床試驗,旨在評估呋喹替尼在美國晚期實體瘤患者中的安全性、耐受性和藥代動力學特性(clinicaltrials.gov 註冊號:NCT03251378)。用於治療轉移性結直腸癌和轉移性乳腺癌患者的概念驗證試驗於2019年開始。

 

呋喹替尼其他開發計畫

中國胃癌研究:2017年10月,和黃醫藥啟動了FRUTIGA研究。FRUTIGA研究是一項隨機雙盲III期臨床試驗,旨在評估呋喹替尼聯合紫杉醇對比紫杉醇單藥化療治療二線晚期胃癌或胃食管結合部(GEJ)腺癌的療效和安全性。研究計畫納入對一線標準化療無應答的患者。受試者將以1:1的比例隨機分組,接受呋喹替尼聯合紫杉醇或安慰劑聯合紫杉醇治療,並根據胃癌或胃食管結合部腺癌,和體能狀態評分等因素進行分層。研究的主要療效終點為總生存期(OS)。次要療效終點包括無進展生存期(PFS,依據RECIST 1.1進行評估)、客觀緩解率(ORR)、疾病控制率(DCR)、疾病緩解時間和生存質量評分(依據EORTC QLQ-C30,3.0版進行評估)。研究也將探索與呋喹替尼抗腫瘤活性相關的生物標誌物(clinicaltrials.gov 註冊號:NCT03223376)。2020年6月,和黃醫藥完成了一項預設的中期分析,基於預設標準,獨立資料監察委員會(IDMC)建議研究繼續進行。

免疫療法聯合用藥:和黃醫藥已訂立三項合作協定,以評估呋喹替尼與PD-1單克隆抗體聯合療法的安全性、耐受性和療效,包括替雷利珠單抗(BGB-A317, 由百濟神州有限公司開發)、達伯舒®(信迪利單抗,IBI308, 由信達生物製藥(蘇州)有限公司開發)和傑諾單抗(geptanolimab,GB226,由嘉和生物藥業有限公司開發)。

中國香港、上海和美國新澤西州:202093星期四和黃中國醫藥科技有限公司(簡稱「和黃醫藥」或「Chi-Med」)(納斯達克/倫敦證交所:HCM)啟動了一項HMPL-453治療晚期肝內膽管癌(IHCC)患者的II期臨床試驗,肝內膽管癌屬於肝癌的一種。HMPL-453是一種靶向成纖維細胞生長因子受體(「FGFR」)的新型小分子抑制劑。

該研究是一項單臂、多中心、開放標籤的臨床試驗,旨在評估HMPL-453治療至少經過一線全身性治療失敗,並伴有FGFR2融合的晚期肝內膽管癌患者的療效、安全性和藥代動力學特性。

該研究的主要結果指標為客觀緩解率(ORR)。次要結果評估包括初步療效指標,例如疾病控制率(DCR)、到達疾病緩解的時間(TTR)、緩解持續時間(DoR)、無進展生存期(PFS)和總生存期(OS)。該項研究的其他詳情可登錄clinicaltrials.gov,檢索 NCT04353375 查閱。

 

關於肝內膽管癌

肝內膽管癌是一種起源於膽管細胞的癌症[1]。中國每年新增肝癌病例超過39萬例,佔2018年全球新增肝癌病例的近半數[2],[3]。肝內膽管癌是僅次於肝細胞癌的第二常見的肝臟原發性惡性腫瘤,新診斷的肝癌中有10%至20%為肝內膽管癌[4]。肝內膽管癌患者中約有10-15%伴有FGFR2融合[5],[6]。肝內膽管癌患者的長期生存率較肝細胞癌患者低,這可能與較高的局部和遠端轉移傾向以及缺乏有效的全身性治療選擇有關[4]

 

關於成纖維細胞生長因子受體(FGFR)

FGFR是受體酪氨酸激酶的亞族之一。 FGFR信號通路的激活是數個生物過程的關鍵。正常生理情況下,FGF/FGFR信號通路參與胚胎髮育(器官發生和形態發生)、組織修復、血管生成、神經內分泌和代謝平衡。鑑於其在許多重要生理過程中的複雜性和關鍵作用,已發現異常的FGFR信號傳導是腫瘤生長、促進血管生成以及抗腫瘤治療抗性產生的誘因。
