      Abstract
      Background
      Given the synergy effect of immunotherapy and anti-angiogenic therapy in advanced NSCLC, FDA approved atezolizumab plus bevacizumab and chemotherapy as first-line treatment. However, chemo-free first-line strategy of PD-1/PD-L1 inhibitor combining angiogenesis modulator remains to be explored. This is the first trial evaluating sintilimab (anti-PD-1) plus anlotinib (multi-target TKI against tumor angiogenesis and proliferation) in treatment-naive advanced NSCLC patients and is one arm of Phase I anlotinib-based trial (NCT03628521).

      Methods
      Treatment-naive, stage IIIB/IV NSCLC patients aged 18-75 with ECOG PS 0-1 were eligible. Patients with EGFR, ALK or ROS1 mutations were excluded. Participants were given intravenous sintilimab (200mg q3w) and oral anlotinib (12mg/d 2 weeks on/1 week off) until progression or unacceptable toxicity. The primary endpoints were ORR and safety. The secondary endpoints included DCR, PFS and OS. AEs were graded according to CTCAE v4.0.

      Results
      From September-2018 to February-2019, 22 patients were enrolled. Most were male (95.5%), former/current smokers (63.6%) and squamous cell histology (54.5%). 4 had baseline brain metastases. All patients have received at least once tumor assessment as of Jul-3th-2019. Among all, 16 achieved confirmed PR, 6 achieved SD, ORR was 72.7% (49.8%, 89.3%) and DCR was 100% (84.6%, 100%). 6 month PFS rate is 93.8% (95%CI: 63.23%, 99.10%). Overall, sintilimab and anlotinib was well tolerated. 6 (27.3%) had grade 3 and above treatment related adverse event (TRAE). The most common TRAE included fecal occult blood, hyperuricemia, hyponatremia, foot-hand syndrome, etc. 21 patients had baseline PD-L1-evaluated and 18 patients got TMB status (details in table). Notably, 5 of 6 SD patients developed cavities inside, suggesting a synergetic anti-tumor effect from combination regimen.

      Conclusion

      In this interim analysis, sintilimab plus anlotinib showed high ORR (72.7%) and DCR (100%) with tolerable safety profile, supporting worthy of further development from this convenient chemo-free regimen in first line setting.

      MA25.09 - Navigating Anlotinib Precision Therapy Through the Genetic Profiling of Circulating DNA in Non-Small Cell Lung Cancer Patients (Now Available) (ID 1055)

      Background

      Anlotinib is an oral multi-targeted anti-angiogenic drug, and its clinical predictor for non-small cell lung cancer (NSCLC) patients is still elusive. The aim of this study is to screen predictor for anlotinib via non-invasive genetic profiling of plasma cell free DNA and circulating tumor DNA (cfDNA & ctDNA).

      Method

      Tumor-specific target capture to profile the circulating DNA of ALTER0303 (Evaluating NSCLC clinical anti-tumor efficacy through anlotinib therapy) study participants. Acquired mutations were screened out via comparing genetic profiling between baseline (BL) and progression disease (PD), and were used for anlotinib stratification. Based on the sequencing data at BL, tumor mutation index (TMI) was established from three independent predictors germline and somatic mutation burden (G+S MB), nonsynonymous and synonymous mutation burden (N+S MB) and unfavorable mutation score (UMS), and was used for predicting anlotinib responders. In addition, TMI combined with IDH1Exon4 mutation status also be examined for serving as predictor for anlotinib stratification.

      Result

      Our data firstly indicated no benefit (NB, PFS ≤ 45 days) patients can be mainly excluded via analysis of ARID1A and BRCA2 genetic profiling. Secondly, for the no durable benefit (NDB, 45 days < PFS ≤ 130 days) and durable clinical benefit (DCB, PFS > 130 days) patients, harboring lower mutation burden (G+S MB, N+S MB, and UMS) received more benefit from anlotinib therapy. Subsequently, we found the predictor-TMI can predict anlotinib responders upon discovery cohort (Median PFS: 210 days vs 126 days; p = 0.0238; AUC = 0.77), and validation cohort (Median PFS: 210 days vs 127 days; p = 0.0352) and all patients (Median PFS: 210 days vs 127 days; p = 0.0044) more effectively. Furthermore, the IDH1Exon4 mutation was identified as an unfavorable factor to anlotinib therapy under TMI-based stratification. Lastly, the TMI plus IDH1Exon4 mutation status predict response to anlotinib significantly (Median PFS: 210 days vs 127 days, p < 0.0001, AUC = 0.90; Median OS: 423 days vs 162 days, p < 0.0001, AUC = 0.80).

      Conclusion

      This study provides circulating DNA sequencing-based stratification for underlying anlotinib responders via non-invasive approach, and thus potentially improve clinical outcome for NSCLC patients at 3rd line.

      P1.01-95 - Efficacy and Safety of Anlotinib in Combination with Chemotherapy as First-Line Therapy in Advanced Non-Small Cell Lung Cancer (NSCLC) Patients (ID 2296)

      09:45 - 18:00  |  Author(s): Chunlei Shi

      • Slides

      Background

      Anlotinib (AL3818) is a novel multi-target angioenesis TKI targeting the VEGFR, FGFR, PDGFR and c-Kit. In the ALTER0303 trial, Anlotinib as third-line treatment significantly improved progress-free survival (PFS) and overall survival (OS) in advanced NSCLC patients. This is the first trial evaluating the combination of chemotherapy and anlotinib in treatment-naive advanced NSCLC and is one arm of Phase II anlotinib-based trial (NCT03628521).

      Method

      Patients with previously untreated EGFR/ALK/ROS1 negative advanced NSCLC were enrolled. Eligible patients received anlotinib (12 mg QD from day 1 to 14 of a 21-day cycle) combined with carboplatin (AUC 5) and pemetrexed (adenocarcinoma, 500mg/m2)/gemcitabine (squamous, 1.0g/m2,day1&8) for four to six cycles (21-day cycle). Maintenance treatment was followed by using pemetrexed and anlotinib (anlotinib alone for squamous) until disease progression or treatment intolerance. The primary outcome was objective response (ORR) and secondary outcomes were PFS, disease control rate (DCR) and OS.

      Result

      Until the 21st March 2019, the curative effect was assessed in 30 enrolled patients according to the RECIST 1.1. Among these patients, eighteen of them achieved PR (all confirmed), eleven of them achieved SD and only one patient developed to disease progression. The objective response rate was 60.0 % while the disease control rate was 96.7 %. The most common Grade 3 adverse events were decreased platelet count (20 %), hypertriglyceridemia (10 %) and oral mucositis (6.67 %). 3 patients showed Grade 4 decrease of platelet count (10 %), and both of them belong to the gemcitabine group.

      Conclusion

      The combination of anlotinib and chemotherapy showed the potential effect and a manageable safety profile in patients with previously untreated EGFR/ALK/ROS1 negative advanced NSCLC.

      Background

      As a promising multi-target tyrosine kinase inhibitor (TKI), anlotinib hydrochloride significantly improved overall survival (OS) and progression-free survival (PFS) in advanced NSCLC patients in the phase 3 trial ALTER0303. Antiangiogenesis therapy combined with EGFR-TKI has shown excellent efficacy and survival benefits in patients with EGFR mutations. This is the first trial evaluating anlotinib plus erlotinib in treatment-naive advanced NSCLC patients and is one arm of Phase II anlotinib-based trial (NCT03628521).

      Method

      Patients with previously untreated, EGFR mutation–positive (exon 19 deletion or L858R) advanced NSCLC were enrolled. Eligible patients received anlotinib (10 mg QD from day 1 to 14 of a 21-day cycle) combined with erlotinib (at a dose of 150 mg once daily) until disease progression or treatment intolerance. The primary outcome was objective response (ORR) and secondary outcomes were PFS, disease control rate (DCR) and OS.

      Result

      Until the 21st March 2019, 26 patients were enrolled. All are under treatment and 17 have received at least one tumor assessment. Among these patients, fifteen of them achieved PR (9 confirmed, the rest waiting for next assessment), two of them achieved SD and no patient developed to disease progression. The objective response rate was 88.2 % while the disease control rate was 100 %.The most common Grade 3 TRAE were rash (15.38 %), oral mucositis (11.54%) and albuminuria (7.69 %), and no grade 4/5 observation.

      Conclusion

      The combination of anlotinib and erlotinib showed the promising efficacy for previously untreated, EGFR mutation–positive advanced NSCLC patients with a manageable safety profile.
