11547 Background: Anlotinib, a multitargeted tyrosine kinase inhibitor, had been prove to be effective for the treatment of advanced or metastatic soft tissue sarcoma(STS) faild anthracycline chemotherapy. With the lack of prospective data of combination of PDL-1 inhibitor and antiangiogenic agent, we designed a phase 1b study to investigated the efficacy and safety of anlotinib plus TQB2450 in patients with STS. Methods: Eligible patients (age 18-70, ECOG 0-1, with histopathologically confirmed advanced STS, at least one measurable lesion according to RECIST 1.1, and previously received front-line anthracycline chemotherapy) were included and received anlotinib (12mg qd, D1-14, 21d/cycle) plus TQB2450 (1200 mg, IV, D1, 21d/cycle) until disease progression or intolerable toxicities.The primary endpoint was objective response rate (ORR), secondary endpoints included safety, overall survival (OS), progression-free survival (PFS), disease control rate (DCR). Results: From January 2019 to January 2021, 30 pts were enrolled1, 12 alveolar soft part sarcoma and 18 others (7 synovial sarcoma, 4 leiomyosarcoma, 5 undifferentiated pleomorphic sarcoma, 1 fibrosarcoma and 1 epithelioid sarcoma). ORR by RECIST was 36.7%, DCR was 83.3%, 11/30 pts had PR, 14/30 (46.7%) had SD, 5/30 (16.7%) PD. Median PFS was 9.6 m in all pts and 4.9m. in non-ASPS, respectively. Median OS in non-ASPS was 10.27m, while mOS in all pts and both mPFS and mOS in ASPS had not been reached. Notably, to ASPS pts, ORR was 75%, and DCR was 100%. The most common 1-2 grade treatment-related adverse reaction (TRAE) was hypothyroidism (19/30,63.3%)，hypercholesterolemia (16/30, 53.3%) and hypertriglyceridemia (16/30, 53.3%), the most common ≥3 grade TRAEs were hypertriglyceridemia (3/30, 10%). 6 SAE (20%) occurred, including 2 pneumothorax, 1 Immune associated hapatic injury, 1 hypotension, 1 Immune myocarditis and 1 diabetic ketoacidosis. Conclusions: The combination of anlotinib and TQB2450 showed promising activity in second-line treatment of advanced STS, especially in ASPS, with well tolerance and acceptable toxicity.

e22518 Background: There is no standard therapy for soft tissue sarcoma (STS) patients progressing after first-line chemotherapy. Anlotinib significantly prolonged PFS in advanced STS patients in the earlier results of ALTER0203. In view of regional differences, we further analysis results from Affiliated Sixth People’s Hospital, Shanghai Jiaotong University, one center in this IIB trial. Methods: Patients aged from 18 to 70 with advanced STS, progressing after anthracycline-based chemotherapy (not adapted to alveolar soft part sarcoma (ASPS) and clear cell sarcoma (CSC)), angiogenesis inhibitor naive, at least one measurable lesion according to RECIST 1.1, were eligible. Patients were randomised in a 2:1 ratio to receive anlotinib (12 mg per day 2 weeks on and 1 week off) or placebo. Primary endpoint was progression free survival (PFS). Secondary endpoints were overall response rate (ORR), disease control rate (DCR). Results: This center of ALTER0203 enrolled 48 eligible patients who received either anlotinib (n = 32) or placebo (n = 16). Leiomyosarcoma (LMS) (13/48), ASPS (12/48), synovial sarcoma (SS) (11/48) were major subtypes. The median PFS was 1.57 months (95% CI: 1.19-1.95) for placebo versus 6.27 months (95% CI: 1.89-10.65) for anlotinib ( P= 0.009). ORR was 0% (0/16) for placebo versus 18.75% (6/32) for anlotinib ( P= 0.16); DCR was 18.75% (3/16) for placebo versus 56.25% (18/32) for anlotinib ( P= 0.02). The most common adverse events (AEs) were hypertension, elevated TSH, hypertriglyceridaemia (HTG). The most common Grade ≥3 AEs were menstrual disorder, hypertension, gamma glutamyl transferase (GGT) elevation and lipase elevation. Conclusions: The efficacy and safety of anlotinib is further confirmed in advanced STS patients regarding regional differences. Clinical trial information: NCT02449343. [Table: see text]

Background: Myxofibrosarcoma is a type of soft-tissue sarcoma that is associated with high rates of local recurrence and distant metastases. The first-line treatment for metastatic soft-tissue sarcoma has conventionally been doxorubicin-based. Recent evidence suggests that myxofibrosarcoma may be molecularly similar to undifferentiated pleomorphic sarcoma (UPS), which is particularly sensitive to gemcitabine-based therapy. The goal of this study was to evaluate the activity of gemcitabine-containing regimens for the treatment of metastatic myxofibrosarcoma refractory to doxorubicin. Material and Methods: We retrospectively evaluated seven consecutive cases of metastatic myxofibrosarcoma at our institution treated with gemcitabine-based therapy in the second-line setting, after progression on doxorubicin. Baseline clinical and baseline characteristics were collected. Primary endpoints were objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). Results: After progression on first-line doxorubicin, a partial, or complete radiological response was observed in four of seven patients who received gemcitabine-based chemotherapy. With a median follow-up of 14 months, median progression-free and overall survival were 8.5 months and 11.4 months, respectively. Conclusions: Gemcitabine-based chemotherapy was associated with encouraging response rates in this cohort, similar to those seen in UPS. Both entities could be studied together for novel gemcitabine-based regimens.

11021 Background: After we demonstrated the activity of REG in pts with advanced non-adipocytic STS (MirTLO 2016), we conducted a dedicated study in pts previously treated with PAZ+chemo. Methods: We report here the 5th cohort of a double-blind randomized phase 2 trial (NCT01900743). Pts were treated with regorafenib (160mg/d, 21/28d) or placebo (PB). Pts receiving placebo were offered optional cross-over in case of centrally confirmed disease progression. The primary endpoint was centrally-reviewed RECIST-based progression-free survival (PFS), evaluated on the intent-to-treat dataset. A total of 24 events was required to ensure a 90%-power for HR = 0.33 (median PFS, 3·6 vs 1·2 months), with a 1-sided α = 0·1. Overall survival (OS) was a secondary endpoint. Results: From 12/2015 to 10/2017, 37 pts were randomized (18 REG vs 19 PB) and included in the final analysis. The median age was 60 (36-76). There were 28 women (76%). All pts had a performance status 0 or 1. Histological subtypes included 24 leiomyosarcoma (11 vs 13, in REG and PB, respectively), 1 synovial sarcoma (REG), 12 other sarcoma (7 vs 5). All pts had previously been treated with PAZ +chemo (including doxorubicin: 19 vs 17; ifosfamide: 11 vs 3; trabectedin: 11 vs 9; and dacarbazine: 7 vs 6), with 2-6 prior lines. The median relative dose intensity of REG was 0·86, range 0·41-1. Out of 19 pts assigned to placebo, 13 switched to REG after progression. There was no reported objective response. We observed a significant benefit of REG compared to PB in terms of PFS (HR = 0·38; 95%CI, 0·19-0·76; p = 0·007; median PFS = 2·1 vs 1·1 months, respectively), and OS despite the cross-over (HR = 0·41; 95%CI, 0·17-0·98; p = 0·04; median OS = 18·6 vs 8·2 months). Before cross-over, the most common clinically significant grade 3 or higher adverse events were diarrhea (4 vs 0), dyspnea (3 vs 1), arterial hypertension (2 vs 0), hand-foot skin reaction (2 vs 0). Conclusions: The present study demonstrates that regorafenib has a clinically meaningful anti-tumor activity in pts with non-adipocytic soft tissue sarcoma pretreated by both chemotherapy and pazopanib, improving PFS and OS.

Abstract Background: The evidence that albumin-bound paclitaxel (nab-paclitaxel) is safe and efficacious for the treatment of many types of malignant tumors is continuously increasing. However, the clinical data and evidence of nab-paclitaxel and gemcitabine in metastatic soft tissue sarcoma (STS) treatment are rare.Methods: The data of 17 patients with metastatic STS who received nab-paclitaxel/ gemcitabine chemotherapy between January 2019 and February 2020 were retrospectively reviewed. All patients were treated with nab-paclitaxel/ gemcitabine only after doxorubicin-based chemotherapy had failed. We evaluated the median progression-free survival (m-PFS), disease control rate (DCR), objective response rate (ORR) and adverse events (AEs) in these patients.Results: The m-PFS was 6 months (95% CI, 2–9 months), ORR was 41.2% and DCR was 70.6%. The average change in target lesion diameter from baseline was -19.06±45.74%. While the majority of the treatment patients experienced grade 1 or 2 AEs, grade 3 or 4 AEs were not common, but included neutropenia (17.6%), fatigue (11.8%), anemia (11.8%), leukopenia (11.8%), nausea (5.9%), peripheral neuropathy (5.9%), diarrhea (5.9%), and thrombocytopenia (5.9%). No treatment-related deaths occurred. Conclusion: Nab-paclitaxel/ gemcitabine combination chemotherapy is comparatively effective in the treatment of STS, demonstrates low toxicity, and is worthy of further study.

e22550 Background: Olaratumab is a humanized monoclonal anti platelet-derived growth factor receptor α antibody that has been approved in combination with doxorubicin for the treatment of patients with metastatic soft tissue sarcoma (STS). The purpose of this retrospective study was to assess the clinical efficacy in STS patients treated with olaratumab in a real-world setting in Austria. Methods: Retrospectively collected, longitudinal data from patients treated between November 2016 and September 2018 at 9 Austrian centers were obtained from respective medical charts. Eligible patients were all patients who received at least one dose of olaratumab. Parameters of most interest collected were response rates, progression-free survival (PFS) and overall survival (OS). Results: Altogether 55 patients were included into analysis. Median age was 58 years. In total, 65.5% (n = 36), 21.8% (n = 12) and 12.7% (n = 7) received olaratumab as first-, second- or ≥ third-line treatment, respectively. Olaratumab was administered either in combination with doxorubicin (81.8%, n = 45) or liposomal doxorubicin (16.4%, n = 9); 1 patient received olaratumab as upfront monotherapy. Median PFS and OS were 2.6 and 11.4 months. The objective response rate was 11.4 % and the disease control rate was 40.9 %. Conclusions: In this real-world analysis outcome was less pronounced compared to the results of the Phase Ib/II approval trial ( Tap WD et al. Lancet 2016). Thus, the results of the ongoing phase III trial (NCT02451943) are urgently needed to confirm the efficacy of the combination of olaratumab and doxorubicin in STS patients.

Introduction Soft tissue sarcoma(STS) is a rare and heterogeneous group of disorders with dismal outcomes in metastatic setting. Pazopanib and oral metronomic chemotherapy (OMT) have been evaluated as therapeutic options in this cohort. Materials and methods We conducted a retrospective, single center study evaluating 45 patients with unresectable and/or metastatic STS, who received pazopanib or oral metronomic regimen as per instituitonal protocol between January 2013 and December 2019. An informal cost minimisation analysis was conducted for both OMT and pazopanib arms, considering equivalent outcomes for both (PFS and OS). Results Median PFS in OMT and Pazopanib groups was 4.13 months and 3.53 months,respectively (HR1.31, 95% CI:0.68–2.51, p = 0.41) Only one patient in the OMT group achieved an objective response (partial response) and no objective response was noted in the pazopanib group. The incidence of grade III/IVtoxicities was higher with pazopanib than with OMT (p = 0.08). There were no toxicity related deaths noted in either arm. Conclusions Our study demonstrates that OMT have a similar progression free survival (PFS) and overall survival (OS) in metastatic STS. This study raises the possibility that OMT might be an equally efficacious and less toxic alternative to pazopanib, without compromising survival outcome especially in LMIC.

11551 Background: Based on the central role played by the vascular endothelial growth factor receptor (VEGFR) in immunosuppression, we assessed the activity and safety of VEGFR inhibitor pazopanib plus anti-PD-L1 blockade durvalumab in soft tissue sarcoma (STS). Methods: We did a single-arm, single-center, phase 2 study that enrolled patients with metastatic or locally advanced STS aged 19 years or older, ECOG PS 0-1, with at least one measurable lesion, and received at least one previous line of systemic therapy. Patient were given pazopanib 800 mg orally daily and durvalumab 1500 mg intravenously for 60 min every 3 weeks. The primary endpoint was investigator-assessed objective response. Results: Between September 2019 and October 2020, 47 participants were enrolled, of whom 46 (97.9%) were evaluable for the efficacy analyses. With a median follow up of 12.3 months, complete and partial response (PR) was achieved in 1 (2.2%) and 12 (26.1%) patients, resulting in 28.3 % of objective response rate. Median time to achieve PR was 1.4 months and median duration of response was 11.0 months. The most common treatment-related adverse events of any grade include fatigue (20 [42.6%]), anorexia (17 [36.2%]), diarrhea (17 [36.2%]), and AST elevation (16, [34.0%]). Thirty-one patients (67.3%) had progressive disease, and the median progression free survival was 8.6 months (95% CI 3.6-13.6). Conclusions: Durvalumab and pazopanib showed encouraging activity in patients with advanced STS. Molecular predictors with whole exome and RNA sequencing will be presented. Clinical trial information: NCT03798106.

Abstract Background Pazopanib, a multitargeted tyrosine kinase inhibitor, is recommended as the standard treatment for refractory soft tissue sarcoma (STS). However, there are comparatively few molecular determinants for predicting pazopanib efficacy. Based on correlative studies regarding the predictive impact of PD-L1, we investigated the clinical relevance of PD-L1 expression and evaluated its value for predicting pazopanib efficacy. Methods Tumour tissues from patients with advanced STS who went on to receive pazopanib were assessed for PD-L1 expression. Immunohistochemistry was performed using an anti-PD-L1 antibody, and the PD-L1 tumour proportion score (TPS) was calculated as the percentage of at least 100 viable cells with positive expression, defined as TPS ≥ 1%. ResultsAmong the 67 patients, 8 (11.9%) achieved partial response and a median progression-free survival (PFS) of 4.8 months (95% CI 3.8-5.7). PD-L1 expression in tumour cells was detected in 13 (19.4%) cases and the TPS scores ranged from 1‒100%, as follows: 0 (n=54, 80.6%), 1‒9% (n=3, 4.5%), 10‒49% (n=9, 13.4%), and ≥50% (n=1, 1.5%). PD-L1 positive tumours exhibited a poorer response to pazopanib treatment than the PD-L1 negative tumours (0% vs 14.8%, P=0.07). PD-L1-positive tumours had significantly shorter PFS than the PD-L1-negative tumours (median PFS 2.8 vs 5.1 months, P=0.003), and PD-L1 positivity was an independent predictor of poor response to pazopanib treatment (HR 2.77, 95% CI; 1.45-5.56, P=0.006). ConclusionWe identified that PD-L1 expression can help predict the clinical outcome of patients with advanced STS treated with pazopanib. Based on our study, stratification should be actively considered in order to identify patients who will benefit from pazopanib or further therapeutic strategies for future clinical trials.

9518 Background: The benefits of BRAF + MEK inhibition (dual combo) in pts with BRAF V600-mutant ( BRAFV600) melanoma are known. Preclinical data supports inhibiting CDK 4/6 and BRAF + MEK (triple combo) to improve antitumor activity. We report safety and preliminary efficacy from a phase 1b/2 study (NCT01543698) of encorafenib (ENCO; a selective BRAF kinase inhibitor), binimetinib (BINI; a MEK inhibitor), and ribociclib (RIBO; a CDK 4/6 inhibitor). Methods: Phase 1b of this open-label, multicenter study enrolled pts with confirmed BRAFV600advanced solid tumors. Escalating doses of RIBO 100 mg-600 mg QD for 3 wk on/1 wk off were administered with ENCO 200 mg QD + BINI 45 mg BID in successive cohorts (6 pts each) until the maximum tolerated or recommended phase 2 dose (RP2D) was reached. Due to potential pharmacokinetic interactions with RIBO, the ENCO dose was lower than the dual combo RP2D (450 mg QD). Dose escalations followed an adaptive Bayesian model. In phase 2, the triple combo was tested in pts with BRAFV600melanoma naïve to prior BRAF inhibitor treatment; the primary endpoint was objective response rate (ORR) per RECIST v1.1. Results: In phase 1b (n = 21), no dose-limiting toxicities were reported and the triple combo RP2D was ENCO 200 mg QD + BINI 45 mg BID + RIBO 600 mg QD. ENCO AUC was slightly lower than at the dual combo RP2D. In phase 2 (n = 42), 59.5% pts had an ECOG PS of 0 and 43% of pts had elevated lactate dehydrogenase. The most common (≥5%) grade 3/4 toxicities were neutropenia (26.2%), increased alanine transaminase (14.3%), diarrhea (7.1%), and anemia (7.1%). Ten pts (23.8%) discontinued treatment due to an AE, of which 4 were increased transaminases. The confirmed ORR was 52.4%, including 4 complete responses, 18 partial responses, and 15 pts with stable disease. Median duration of exposure in phase 2 was 9.1 mo (range, 0.0-21.6). Median progression-free survival was 9.0 mo (95% confidence interval, 7.0-11.1). Conclusions: Triple therapy with ENCO + BINI + RIBO in this small trial of pts with high disease burden was associated with responses in over half of pts and some evidence of increased toxicity. Clinical trial information: NCT01543698.

<b><i>Purpose:</i></b> As a small-molecule tyrosine kinase inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2), apatinib has shown a survival benefit in multiple solid tumors. This study aims to evaluate the efficacy and safety of apatinib in patients with metastatic, recurrent cervical cancer after failure of radiotherapy and first-line chemotherapy. <b><i>Methods:</i></b> A total of 42 patients between June 2018 and March 2019 were involved in this study. All patients orally received apatinib once daily in a 4-week cycle until disease progression or adverse events that prohibit further therapy. The primary endpoint was progression-free survival (PFS), the secondary endpoints were overall survival (OS), objective response rate (ORR), disease control rate (DCR), health-related quality of life (HRQoL) and adverse events. <b><i>Results:</i></b> During a median follow-up of 13 months, 8 patients achieved a partial response and 24 cases achieved stable disease. None of them reported a complete response. The ORR and DCR were 19.0 and 76.2%, respectively. The median PFS was 6.0 months (95% CI 4.9–7.1), and the median OS was 12.0 months (95% CI 10.1–13.9). The global health score/HRQoL improved significantly following 3-cycle treatment (50.4 ± 12.5 vs. 60.1 ± 11.8; <i>p</i> &#x3c; 0.01). The most frequent grade 3–4 adverse events were hand-foot syndrome, hypertension and fatigue. <b><i>Conclusion:</i></b> Apatinib should be an effective and tolerable treatment option for patients with metastatic, recurrent cervical cancer after failure of radiotherapy and first-line chemotherapy.
