Core Viewpoint - The approval of the new indication for Ivosidenib (依沃西单抗) by Kangfang Biopharma (康方生物) did not positively impact the company's stock price, which fell by 11.83% on April 28 due to concerns over the overall survival (OS) data, which showed clinical benefits compared to Keytruda (K药) but lacked statistical significance [1][4][6]. Summary by Sections Drug Approval and Clinical Data - Ivosidenib received approval for a second indication as a first-line treatment for locally advanced or metastatic non-small cell lung cancer (NSCLC) with PD-L1 positivity (TPS≥1%) and negative for EGFR and ALK mutations [4]. - The approval was based on positive results from the AK112-303/HARMONi-2 clinical trial, which demonstrated a median progression-free survival (PFS) of 11.14 months for Ivosidenib compared to 5.82 months for Keytruda, with a hazard ratio (HR) of 0.51, indicating a 49% reduction in the risk of disease progression or death [4][5]. Overall Survival Analysis - A mid-term analysis at 39% maturity showed that Ivosidenib reduced the risk of death by 22.3% compared to Keytruda, although this result did not achieve statistical significance [6][8]. - The total survival data is considered the gold standard for evaluating the efficacy of cancer therapies, and there are differing opinions on the interpretation of these results [6][9]. Market Reaction and Future Prospects - The market's reaction to the OS data has been viewed as misaligned with the essence of the clinical findings, according to Kangfang's chairman, Xia Yu [6][8]. - The ongoing competition with Keytruda is significant, as lung cancer remains the most prevalent and deadly cancer type in China, with Ivosidenib's performance in clinical trials being closely monitored [9][10]. Upcoming Research - The HARMONi-7 study, conducted by Summit, will further evaluate Ivosidenib against Keytruda in patients with high PD-L1 expression, with a focus on achieving statistically significant benefits in overall survival [10]. - This study is crucial for determining whether Ivosidenib can genuinely challenge Keytruda's dominant position in the market [10].

Core Viewpoint - Kangfang Biopharma's dual antibody drug Ivosidenib has successfully challenged PD-1 monoclonal antibodies in head-to-head trials, indicating potential shifts in the PD-1 market for immunotherapy [1][6]. Company Summary - On April 23, Kangfang Biopharma's stock price reached a historic high of 100 HKD per share following the announcement of Ivosidenib's success in head-to-head trials against BeiGene's Tislelizumab [2]. - Ivosidenib (PD-1/VEGF dual antibody) demonstrated significant clinical benefits in a Phase III clinical trial for advanced squamous non-small cell lung cancer (sq-NSCLC), achieving the primary endpoint of progression-free survival (PFS) [3]. - The trial results showed that Ivosidenib combined with chemotherapy outperformed Tislelizumab combined with chemotherapy, with significant PFS benefits observed in both PD-L1 positive and negative populations [3]. Industry Summary - Ivosidenib is the world's first PD-1/VEGF dual-specific tumor immunotherapy drug, approved for use in China for specific lung cancer patients as of May 2024 [4]. - The drug is currently undergoing head-to-head clinical trials to expand its indications, with successful outcomes potentially leading to significant commercial value [4]. - The PD-1 market is highly competitive, with BeiGene's Tislelizumab holding a leading market share in China, generating revenue of 621 million USD in 2024 [4]. - Merck's Keytruda is the highest-selling PD-1 drug globally, with projected revenues of 29.482 billion USD in 2024 [5]. - Lung cancer remains the most prevalent and deadly malignancy worldwide, with PD-1 combined chemotherapy being the current standard first-line treatment for non-small cell lung cancer [6].

在此次头对头试验中，依沃西联合化疗把替雷利珠单抗联合化疗作为对照组。康方生物表示， HARMONi-6临床试验共入组532例受试者，中央型鳞癌占比约为63%，与真实世界患者分布一致。研究 数据表明，在意向治疗人群(ITT)中，依沃西联合化疗组的患者无进展生存期（PFS）相较对照组，获得 了决定性胜出的阳性结果。 在安全性方面，依沃西组总体表现良好，未发现新的安全性信号。与治疗相关的严重不良反应发生率以 及三级及以上出血事件发生率与对照组相似。 记者注意到，去年依沃西在单药头对头临床试验中战胜帕博利珠单抗（K药），此次也是依沃西第2个 头对头PD-1疗法取得阳性结果的III期临床研究，来自全国共66家临床研究中心参与了此项研究。 肺癌根据癌细胞的形态，可初步分为非小细胞肺癌（NSCLC）和小细胞肺癌(SCLC)。其中NSCLC占比 约85%，它又能进一步被分为三类，分别是腺癌、鳞癌和大细胞癌，肺鳞癌占所有肺癌病例的 25%~30%。 《每日经济新闻》记者了解到，大部分驱动基因突变发生在肺腺癌，肺鳞癌驱动基因突变较少，患者的 生存预后相对较差。随着免疫治疗药物的上市，sq-NSCLC患者的生存期得到明显改善。恒瑞 ...
