ASCO亮点:聚焦下一代免疫疗法与抗体药物偶联物

Healthcare ASCO Highlights: Spotlight onnext-gen IO & ADCs Innovent: ASCO data reinforce IBI363’s potentialasapotentialnext-generation IO.We view IBI363 as a highly promising candidate in theIO-resistant sq-NSCLCspace, supported by an impressive mPFS of 7.3months in monotherapy, whichisverycompetitivecompared tootherinnovative agents.Innovent plans to initiate a Ph3 trial of IBI363 in IO-resistant sq-NSCLC in 2H25. In3L+CRC,IBI363hasshownsuperior earlyefficacy signals and a more favorablesafetyprofile. IBI363monodeliveredanORRof12.7%andanmOSof16.1months—bothsignificantlyoutperforming fruquintinib.IBI363 also appears even more competitive incombination with bevacizumab.Innovent plans to initiate a Ph3 study ofIBI363 plus bevacizumab in 3L MSS CRC in 2H25, andisalsorunning aPh2 trialofIBI363+ SoCin the first-line setting.Moreover,IBI363 holdsmeaningfulpotentialinmelanoma,particularlyintheimmune-coldsubtypes ofacral and mucosal melanoma.In IO-treatedacral and mucosalmelanomapatients, the drug demonstrated an ORR of 28.4% and mPFSof 5.7 months—substantiallybetterthan currently availablePD-1 mAbs.Innovent has initiated a pivotal Ph2 trialofIBI363vsKeytruda in first-lineacral or mucosal melanoma.3SBio:BIC potentialofSSGJ-707in 1L PD-L1+ NSCLC.SSGJ-707 China Healthcare Sector Jill WU,CFA(852) 3900 0842jillwu@cmbi.com.hk Andy WANG(852) 3657 6288andywang@cmbi.com.hk Cathy WANG(852) 3916 1729cathywang@cmbi.com.hk (707)has demonstrated a 72% ORR in treatment-naïve PD-L1+ NSCLCpatients, notably higher thanAK112/Ivonescimab’s 60% ORR in its Ph1bHARMONi-5trialandBNT327’s47.1%ORRinitsPh1/2trial(NCT05918445). 707 has also showna comparable and manageablesafety profile relative to its peers. Thepotentialreadout of mPFS for 707 inPh2 1L PD-L1+ NSCLCin late 2025 will give us better visibility of its BICpotential.Asgloballythe 2ndPD-(L)1/VEGFbsAbto initiate a Ph3 trial in 1LNSCLC,707has recentlyentered a H2H Ph3 trial vs Keytruda in 1L PD-L1+ NSCLC, with a similar study design toAK112’sHARMONi-2.3SBiorecentlyout-licensed 707’s ex-China rights to Pfizer,securing an upfrontpayment of US$1.25bn, up to US$4.8bn inpotential milestones, andtieredroyalties.We expect Pfizer to accelerate the global development of 707.Henlius:Strong potential ofHLX43(PD-L1 ADC)in bothIO-resistant sq-and nsq-NSCLC. In early clinical data, HLX43 achieved an ORR of40.0% (6/15)in IO-resistant sq-NSCLC and 33.3% (2/6) in IO-resistant nsq-NSCLC—competitive performance compared to other leading assets underdevelopment.In cross-trial comparisons, IBI363(PD-1/IL2)and SKB264(TROP2 ADC)reported ORRs of 43.3% and 30.0%, respectively, in IO-resistant sq-NSCLC, and 28.0% and 22.2% in IO-resistant nsq-NSCLC.HLX43 is currently being evaluated in a Ph2 trial for IO-resistant NSCLC,with additional Ph2 programs ongoing acrossbroadtumor types,i.e.HNSCC,ESCC,HCC,NPC,etc.HLX43isalsobeingexploredincombination with serplulimab(PD-1), which couldbring itspotential use infront-linespendingfurthervalidation.WethinkHLX43presentsacompelling opportunity for global partnerships.
