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.

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.

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.

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. Clinical trial information: NCT01900743.

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.

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.

The Italian Sarcoma Group performed this retrospective analysis of patients with advanced soft tissue sarcoma, pretreated with ≥1 anthracycline-based treatment, and treated with trabectedin every three weeks. Primary endpoint was to describe real-life use of trabectedin across Italy. Secondary endpoints included objective response rate (ORR) and safety. Overall, 512 patients from 20 Italian centers were evaluated. Leiomyosarcoma (37.7%)/liposarcoma (30.3%) were the most prevalent histological types (abbreviated as L-sarcoma). Patients received a median of four trabectedin cycles (range: 1–40), mostly as a second-line treatment (~60% of patients). The ORR was 13.7% superior (p < 0.0001) in patients with L-sarcoma compared with patients with non-L-sarcoma (16.6% vs. 9.0%). Median progression-free survival (PFS) was 5.1 months, whereas median overall survival (OS) was 21.6 months. Significantly better PFS and OS were observed in patients with L-sarcoma, those with objective responses and/or disease stabilization, treated in an early line and treated with reduced dose. Bone marrow toxicity (61.4%) and transaminase increases (21.9%) were the most common grade 3/4 adverse events. The results of this real-life study suggest that trabectedin is an active treatment, which is mostly given as a second-line treatment to patients with a good performance status and high-grade, metastatic L-sarcoma (clinical trial information: NCT02793050).

Study Results

Purpose Sarcomas are among the most proangiogenic malignancies in preclinical models. Phase I study results for ABT-510, which inhibits angiogenesis via a novel thrombospondin-mimetic mechanism, suggested activity in soft tissue sarcoma (STS) patients. This phase II study further evaluated the safety and efficacy of ABT-510 in advanced STS patients. Patients and Methods Patients with metastatic or unresectable STS were randomly assigned to treatment with one of two ABT-510 dose schedules (20 mg once a day [20 mg], n = 42; or 100 mg twice a day [200 mg], n = 46), which were self-administered subcutaneously in 28-day treatment periods. End points included progression-free survival (PFS), objective response rate (ORR), overall survival (OS), and safety. Results Median PFS for the 20-mg arm was 94 days, with 4- and 6-month PFS rate estimates of 42% and 24%, respectively. Median PFS for the 200-mg arm was 64 days, with 4- and 6-month PFS rate estimates of 41% and 32%, respectively. Although only one objective response was noted, stable disease was observed in 52% (20 mg) and 48% (200 mg) of patients. Median OS was 431 days (20 mg) and 295 days (200 mg). ABT-510 was well tolerated. Rare treatment-related grade 3 or 4 adverse events were one event each of hypotension, deep vein thrombosis, and hypophosphatemia. ABT-510 pharmacokinetics were dose proportional, time independent, and consistent with those in previous studies. Conclusion ABT-510 had a favorable safety profile, and the rate of disease control and OS times were encouraging. However, with low ORR and lack of dose response, the study failed to yield compelling evidence of strong single-agent activity in STS.
