11013 Background: Results of previous study showed high objective response but short-term activity of apatinib in advanced osteosarcoma. Given the recent success of immunotherapies, combinations of antiangiogenics with immune checkpoint blockers have become an attractive strategy. We aimed to investigate the activity of apatinib in combination with camrelizumab in patients with inoperable high-grade osteosarcoma progressing after chemotherapy. Methods: We did this open-label phase 2 trial in Peking University People’s Hospital. We enrolled patients (≥14 years) with advanced osteosarcoma progressing after chemotherapy. Patients received 500 mg apatinib orally taken once daily plus 200 mg camrelizumab intravenous infusion every 2 weeks until disease progression or unacceptable toxicity. The primary endpoint was 6 month progression-free survival (PFS). All analyses were intention-to-treatment. This trial is registered with ClinicalTrials.gov. (NCT03359018). Results: We enrolled 41 patients between January 1, and September 4, 2018. 20 (48.8%, 95%CI 32.8%-64.8%) of 41 patients were progression free at 6 months. Until final follow-up, the objective response rate was 21.95% (9/41). And the 6-m PFS rate and 4-m PFS rate were 54.32% (95% CI 37.62%-68.33%) and 70.00% (95% CI 53.24%–81.73%) respectively. Median PFS was 6.50 (95% CI 4.23–7.50) months while the median OS has not reached yet. And there were no statistical differences in the response rates or PFS between different PD-L1 expression groups ( P=0.153 and 0.231). Whereas target lesions with only pulmonary metastasis had obviously longer PFS than those lesions located at other places ( P <0.001). We also summarized all those lesions’ progression patterns as follows: slow pulmonary lesions’ progression(N=7), stable disease with lung but new lesions outside lung(N=4) and bone lesions’ progression(N=13), of which we found that there was obvious difference in PFS ( P=0.009) between different progression groups.Toxic effects led to dose reductions, or short interruptions, or both in 20 (48.78%) of 41 patients. There were no treatment-related deaths. Conclusions: The combination of apatinib and camrelizumab obviously prolonged PFS than single apatinib in the treatment for patients with advanced osteosarcoma progressing after chemotherapy. Those with pulmonary metastatic lesions obviously had longer PFS. Whether patients benefit from overall survival needs further observation. Clinical trial information: NCT03359018.

BackgroundResults of our previous study showed high objective response but short-term activity of apatinib in advanced osteosarcoma. We aimed to investigate the activity of apatinib in combination with camrelizumab in patients with inoperable high-grade osteosarcoma progressing after chemotherapy.MethodsThis open-label, phase 2 trial was conducted at Peking University People’s Hospital. We enrolled patients with advanced osteosarcoma progressed after chemotherapy. Patients received 500 mg apatinib orally once daily plus 200 mg camrelizumab by intravenous infusion every 2 weeks until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS) and clinical benefit rate at 6 months, which were based on RECIST V.1.1.Results43 patients were enrolled between January 25 and September 4, 2018. With median follow-up time of 48.3 (Q1, Q3, 30.6, 66.6) weeks, 13 (30.23%, 95% CI 17.2%, 40.1%) of 43 patients were progression free at 6 months and the 6-month PFS rate was 50.9% (95% CI 34.6%, 65.0%). Until final follow-up, the objective response rate was 20.9% (9/43) and two patients with durable disease control were observed. Patients with programmed cell death 1 ligand-1 (PD-L1) tumor proportion score ≥5% and pulmonary metastases tended to have a longer PFS in comparison to the others (p=0.004 and 0.017, respectively). Toxic effects led to dose reductions, or interruptions, or both in 24 (55.8%) of 43 patients and permanent discontinuation in 4 (9.3%) patients. There were no treatment-related deaths.ConclusionsAlthough the combination of apatinib and camrelizumab seemed to prolong PFS in comparison to single agent apatinib in treating advanced osteosarcoma, it did not reach the prespecified target of 6-month PFS of 60% or greater. Overexpression of PD-L1 and the presence of pulmonary metastases only were associated with longer PFS.Trial registration numberNCT03359018.

Abstract This randomized, open-label, multi-center phase 2 study (ClinicalTrials.gov, number NCT03116152) assessed sintilimab, a PD-1 inhibitor, versus chemo in patients with advanced esophageal squamous cell carcinoma (ESCC) refractory to first-line (1L) chemotherapy. The primary endpoint was overall survival (OS), while exploratory endpoint was the association of biomarkers with treatment efficacy. The median OS in the sintilimab group was significantly prolonged compared with that of the chemotherapy group, (objective response rates 12.6% and 6.3 %, respectively). Incidence of treatment-related adverse events of grade 3–5 was lower with sintilimab than with chemotherapy (20.2 vs. 39.1 %). Patients with high TCR clonality and low mTBI showed the longest median OS (15.0 mo), while patients with low NLR at 6 wk post-treatment had a significantly prolonged median OS compared with those with high NLR. High expression of T-follicular helper cells or activated B-cell signature was significantly associated with longer progression-free survival in the sintilimab group.

6034 Background: Anlotinib is a novel multi-target tyrosine kinase inhibitor that has previously shown clinical antitumor activity in various cancers, including the phase I study on female genital tumors. This phase II study (ChiCTR1800020116) aims to further evaluate the safety and efficacy of anlotinib, in those patients with recurrent advanced cervical cancer. Methods: Eligible patients were advanced cervical cancer who had received at least two previous lines of chemotherapy. Patients were given anlotinib (12 mg/day) from day 1 to day 14 in a 21-day cycle until disease progression or had unacceptable toxic effects. The primary endpoint of this study was objective response rate (ORR) and the secondary endpoints were progression-free survival (PFS), overall survival (OS) and safety. Results: Between 2018 December and 2019 October, 41 patients (female) were enrolled. As of January 15, 2020, median follow-up duration, from randomization to data cutoff, was 2.6 months (range, 0.7-10.3). Therapeutic evaluation showed the ORR was 32.1% (95%CI, 13.7%-50.6%) and the median PFS was 3.9 months (95% CI, 1.3%-6.5%). The most frequently reported adverse events were lymphocyte count decreased, anemia, hand-foot syndrome, blood uric acid increased, blood creatinine increased, blood thyroid stimulating hormone increased. All frequently occurring AEs were grade 1 or 2. High grade AE was only observed in 1 patient with white blood cells urine positive of grade 3. Neither unexpected safety signals nor treatment related death occurred. Conclusions: Anlotinib showed a promising activity with an acceptable safety profile for patients with recurrent advanced cervical cancer. Clinical trial information: ChiCTR1800020116.

4076 Background: C+A combination therapy displayed high objective response rate, disease control rate, and durable response with a manageable safety profile in patients (pts) with advanced HCC. Here we performed an updated analysis of OS to characterize the OS benefit of C+A in HCC pts. Methods: 70 pts in first-line cohort and 120 pts in second-line cohort were enrolled. Median OS and 2-year OS rate were evaluated via updated data (data cutoff, 3 January, 2021). Median time from enrollment to data cutoff of the total population (N = 190) was 29.1 months (range, 24.0-33.7). Results: OS events had occurred in 58.6% pts in first-line cohort and 60.0% pts in second-line cohort. The median OS was 20.1 months (95% CI, 14.9-NR) and 2-year OS rate was 43.3% (95% CI, 31.3-54.7) in first-line cohort. The median OS was 21.8 months (95% CI, 17.3-26.8) and 2-year OS rate was 44.6% (95% CI, 35.5-53.3) in second-line cohort. Conclusions: Long-term follow-up of C+A demonstrated remarkable survival benefit in advanced HCC pts, which further suggested that C+A is a promising combination therapy in advanced HCC pts.

8074 Background: ABT-869 is a novel orally active, potent and specific inhibitor of vascular endothelial growth factor and platelet derived growth factor receptor tyrosine kinases. Methods: This ongoing, open-label, randomized, multicenter phase 2 trial of ABT-869 at 0.10 mg/kg daily (Arm A) and 0.25 mg/kg daily (Arm B) until progressive disease (PD) or intolerable toxicity, was initiated to assess antitumor activity and toxicity of ABT-869 in patients (pts) with NSCLC. Eligibility criteria included locally advanced or metastatic NSCLC; ≥ 1 prior systemic treatment, and ≥1 measurable lesion by RECIST criteria. The primary endpoint was the progression free (PF) rate at 16 wks. Secondary endpoints were objective response rate (ORR), time to progression (TTP), progression free survival (PFS) and overall survival (OS). CT scans were assessed by the investigator and centrally; central assessment results are provided. Results: 138 patients (pts) were enrolled from 08/07–10/08 from 27 centers with interim data available for 94 pts (Arm A, n=43; Arm B; n=51). Median age was 64 years and 62 years in Arm A and B respectively. For the interim analysis population (Arm A, n=24; Arm B, n=24), 16 (33.3%) pts were PF at 16 wks: 7 (29.2%) in Arm A and 9 (37.5%) in Arm B. The ORR in Arm A (n=30) was 0% and 7.3% in Arm B (n=41). The median TTP and median PFS were 110 and 109 days, and 112 days and 108 days in Arm A and B, respectively. The most common adverse events (AEs) in Arm A were fatigue (35%), nausea (21%), and anorexia (21%), and in Arm B were hypertension (51%), fatigue (51%), diarrhea (43%), anorexia (41%), nausea (31%), proteinuria (31%) and vomiting (26%). The most common grade 3/4 toxicities in the Arm A were fatigue (7%), ascites (5%), dehydration (5%), pleural effusion (5%), and in the Arm B were hypertension (23%), fatigue (8%), PPE syndrome (8%), dyspnoea (6%) and stomatitis (6%). Most AE's were mild/moderate and reversible with interruptions/dose reduction/or discontinuation of ABT-869. Conclusions: ABT-869 demonstrates an acceptable safety profile and appears to be active in NSCLC patients. [Table: see text]

e18046 Background: Platinum and non-platinum doublet chemotherapy has similar efficacy in advanced NSCLC patients (pts). Bevacizumab (B) improves outcomes when added to platinum doublets, but its safety and efficacy in combination with non-platinum doublets is unknown. This study was designed to test the combination of B, docetaxel (D), and gemcitabine (G) in first-line treatment of advanced NSCLC. Methods: Pts with metastatic, non-squamous NSCLC, PS 0-1, and measurable disease by RECIST were enrolled in this open-label, single arm phase II trial. Pts received D (75 mg/m2) on d1, G (900 mg/m2) on d1 & 8, and B (15 mg/kg) on d1 every 21d for up to 6 cycles, followed by B maintenance until progression or 12 mos total. Pts received growth factor d9. CT scans were performed every 6 wks. The primary endpoint was 1-yr progression-free survival (PFS), with secondary endpoints of safety, objective response rate (ORR), overall PFS, and overall survival (OS). Pts with tumor cavitation, untreated brain metastases, and hemoptysis were excluded. Planned enrollment was 46. Results: 13 pts were enrolled from 12/2009 to 4/2011. Pt characteristics: Median age 63 (35-69), 85% male, PS 0 (38%), PS 1 (62%). The median # of cycles of chemotherapy was 6 (1-6), median # cycles of B was 4 (1-15), with 2 pts coming off study prior to the first evaluation (1 grade 5 encephalopathy, 1 grade 4 febrile neutropenia). 5 pts (38%) had chemo dose reduction and 4 (31%) discontinued treatment for toxicity. 3 pts (23%) discontinued B prior to progression, 2 for tumor cavitation and 1 for grade 1 hemoptysis. The grade 3-5 non-hematologic toxicity rate was 69%, with 6 pts (46%) hospitalized with pneumonitis/pneumonia felt possibly related to study drugs. At this point enrollment was halted for safety concerns. The 1-yr PFS was 8%, and the median PFS was 6.9 mos (95% CI 2.0-NYR). 11 pts were evaluable for response, and 6 pts had partial responses for an ORR of 55%. The median OS was NYR with median follow up of 10.9 mos. Conclusions: The combination of B, D, and G was not tolerable at the doses and schedule used in this study. A formal phase I trial is needed if this combination is to be investigated further.

TPS8112 Background: MM remains incurable and patients (pts) typically relapse or become refractory to current treatments. Novel regimens are needed to improve pt outcomes. Elo is a humanized monoclonal IgG1 antibody targeting the cell surface glycoprotein CS1, which is highly expressed on >95% of MM cells. Len/Dex is approved for treatment of relapsed MM and an objective response rate (ORR) of ~60% was reported in phase III trials of this combination in RR MM. In a phase II study (N=73) of Elo (10 or 20 mg/kg) in combination with Len/Dex in pts with RR MM, the 10 mg/kg group (n=36) demonstrated an ORR of 92% and median progression-free survival (PFS) that was not reached after a median follow-up of 14.1 months. Encouraging activity was seen in patients with high-risk cytogenetics and/or stage 2-3 disease. Based on these data, a randomized, open-label phase III trial has been initiated to determine if the addition of Elo to Len/Dex will improve PFS in patients with RR MM compared with Len/Dex alone. Methods: Pts (N=640) with RR MM and 1-3 prior therapies are eligible, including pts with mild or moderate renal impairment. Pts are randomized in a 1:1 ratio to receive 28-day cycles of Len 25 mg PO (days 1-21) and Dex 40 mg PO (days 1, 8, 15 and 22) with or without Elo. Elo dose and schedule is 10 mg/kg IV on days 1, 8, 15, 22 in the first 2 cycles and on days 1 and 15 in subsequent cycles. Dex 8 mg IV + 28 mg PO is used during the weeks with Elo. Treatment will continue until disease progression, death, or withdrawal of consent. Patients will be followed for tumor response every 4 weeks until progressive disease and then survival every 12 weeks. The primary endpoint is PFS (90% power for a hazard ratio [experimental to control arm] of 0.74) and the secondary endpoints are ORR and overall survival. Exploratory endpoints are safety, time to response, duration of response, time to subsequent therapy, health-related quality of life, and pharmacokinetics and immunogenicity of Elo. Potential biomarkers will also be assessed. As of January 10th, 2012, 107 pts were enrolled and 68 pts were treated. NCT01239797.

426 Background: In an open-label, phase IV study of sunitinib as 1st-line treatment (Tx) in Chinese pts with mRCC, median progression-free survival (PFS) and overall survival (OS) were 61.7 and 133.4 wk, respectively; objective response rate (ORR) was 31.1% (Ann Oncol 2012;23:851P). We retrospectively investigated correlations between on-Tx hypertension (HTN), neutropenia (N), and thrombocytopenia (T) and efficacy endpoints in pts from this trial. Methods: HTN was defined by either maximum systolic blood pressure ≥140 mm Hg (S-HTN) or maximum diastolic blood pressure ≥90 mm Hg (D-HTN). Using CTCAE assessment, N grade ≥2 and T grade >1 were used as cut-points for the analyses. Median PFS and OS were estimated by Kaplan−Meier method. The log-rank test was used to compare PFS and OS between groups with and without HTN, N grade ≥2, or T grade >1. Fisher’s exact test was used for ORR. Results: 102 pts were included in the HTN analyses, 60% with S-HTN versus 40% without S-HTN. Pts with S-HTN had greater ORR and longer PFS and OS than pts without S-HTN (Table). (Results were similar with D-HTN; see Table.) 103 pts were included in the N and T analyses, 67% with N grade ≥2 versus 33% with N grade <2, and 56% with T grade >1 versus 44% with T grade ≤1. Pts with N grade ≥2 had significantly greater ORR and significantly longer PFS and OS than pts with N grade <2 (Table). Pts with T grade >1 had greater ORR and significantly longer PFS and OS than pts with T grade ≤1 (Table). Conclusions: The developments of N grade ≥2 and T grade >1 during Tx with sunitinib were significantly associated with better outcome. Median PFS was more than twice as long for pts with S-HTN as for those without S-HTN, but the association did not reach statistical significance. [Table: see text]

492 Background: 3-drug chemotherapy (CT) + BEV (cFOLFOXIRI-BEV) significantly improved efficacy vs FOLFIRI-BEV for 1L mCRC tx, but safety and the impact of subsequent fluoropyrimidine-BEV maintenance tx require further definition. The phase 2 STEAM (NCT01765582) trial assessed efficacy of 1L cFOLFOXIRI-BEV vs FOLFOX-BEV and safety of alternating 2-drug CT (FOLFOX and FOLFIRI) + BEV tx monthly in a sequential sFOLFOXIRI-BEV regimen. Methods: Pts with unresectable, previously untreated mCRC were randomized 1:1:1 to BEV-containing (5 mg/kg) arms (cFOLFOXIRI, sFOLFOXIRI [alternating FOLFOX and FOLFIRI every 4 weeks {q4w}], or FOLFOX q3w) in a 4–6 month induction phase, followed by BEV-containing maintenance tx. Stratification factors included extent of metastatic disease and tumor location. Primary objectives: 1L ORR, 1L progression-free survival (PFS), safety. Secondary objectives: resection and conversion to resectable disease rates, time to 2L PFS, overall survival. ORR was tested with a 1-sided alpha of 5%; tx arms were compared with a stratified 1-sided Cochran-Mantel-Haenszel test. PFS was analyzed descriptively. Results:Among 280 enrolled pts (median age, 57.5 yrs), 186 remainined in the study on July 1, 2015. Efficacy and safety are shown (see Table). Conclusion: While not statistically significant, there was a trend of increased ORR with cFOLFOXIRI-BEV vs FOLFOX-BEV in 1L mCRC tx. Analysis of PFS is ongoing. All 3 regimens were well tolerated. Clinical trial information: NCT01765582. [Table: see text]

TPS597 Background: Deregulation of the FGFR signaling pathway is implicated in various cancers. In iCCA, FGFR genetic aberrations include FGFR2 fusions and, less commonly, FGFR2 M/A. iCCA prognosis is poor, and chemotherapeutic and targeted treatment options are limited. While FGFR2 fusions are acknowledged oncogenic drivers, the oncogenic potential of FGFR2 M/A is less well defined. Derazantinib (DZB) is an investigational, oral small-molecule kinase inhibitor with activity against FGFR1, 2 and 3, which demonstrated antitumor activity in patients with unresectable iCCA with FGFR2 fusions. Based on preliminary efficacy data demonstrating durable responses of > 6 months and a clinically meaningful progression-free survival in a subset of iCCA patients harboring FGFR2 M/A (NCT01752920), the multicenter, multicohort open-label phase 2 study FIDES-01 is evaluating the effect of DZB in separate cohorts of iCCA patients with FGFR2 fusions or FGFR2 M/A. Methods: The new cohort evaluates 300 mg once daily dosing of DZB in patients with unresectable iCCA with FGFR2 M/A per liquid or tissue biopsy-based next generation sequencing and at least one previous systemic therapy. Treatment will continue until progressive disease, intolerance, withdrawal of informed consent, or death. Using a Simon’s two-stage design, the primary endpoint to assess the antitumor activity of DZB is the proportion of patients with PFS at 3 months (PFS3; per RECIST 1.1 central review). Secondary objectives are evaluation of median PFS, objective response rate, duration of response, safety profile, quality of life (incl., QLQ-C30, QLQ-BIL21, EQ-5D), and symptom response from baseline. Current status: The study was initiated in July 2019 with planned enrollment of 43 patients with confirmed FGFR2 M/A. Clinical trial information: NCT03230318.
