Patients with liver-dominant metastatic or primary hepatic soft tissue sarcomas (STS) have poor prognosis. Surgery can prolong survival, but most patients are not surgical candidates, and treatment response is limited with systemic chemotherapy. Liver-directed therapies have been increasingly employed in this setting, and Yttrium-90 trans-arterial radioembolization (TARE) is an understudied yet promising treatment option. This is a retrospective analysis of 35 patients with metastatic or primary hepatic STS who underwent TARE at a single institution between 2006 and 2020. The primary outcomes that were measured were overall survival (OS), liver progression-free survival (LPFS), and radiologic tumor response. Clinical and biochemical toxicities were assessed 3 months after the procedure. Median OS was 20 months (95% CI: 13.9–26.1 months), while median LPFS was 9 months (95% CI: 6.2–11.8 months). The objective response rate was 56.7%, and the disease control rate was 80.0% by mRECIST at 3 months. The following correlated with better OS post-TARE: liver disease control (DC) at 6 months (median OS: 40 vs. 17 months, p = 0.007); LPFS ≥ 9 months (median OS: 50 vs. 8 months, p < 0.0001); ECOG status 0–1 vs. 2 (median OS: 22 vs. 6 months, p = 0.042); CTP class A vs. B (median OS: 22 vs. 6 months, p = 0.018); and TACE post-progression (median OS: 99 vs. 16 months, p = 0.003). The absence of metastases at diagnosis was correlated with higher median LPFS (7 vs. 1 months, p = 0.036). Two grade 4 (5.7%) and ten grade 3 (28.6%) laboratory toxicities were identified at 3 months. There was one case of radioembolization-induced liver disease and two cases of radiation-induced peptic ulcer disease. We concluded that TARE could be an effective and safe treatment option for patients with metastatic or primary hepatic STS with good tumor response rates, low incidence of severe toxicity, and longer survival in patients with liver disease control post-TARE.

10062 Background: Trabectedin (T) is a marine-derived alkaloid used to treat advanced soft tissue sarcomas (STS) after ifosfamide and/or anthracyclins failure. Since then, the FSG evaluated the clinical benefit in re-administrating T after an initial hold, either medically indicated or upon patient’s request. Methods: Following an online request, clinical and histopathological data were collected from six centers of the FSG who declared to have rechallenged patients. Baseline data were collected and analyze will be used. Results: From 1999 to 2011, 49 pts with T drug holiday have been identified (26 male/ 23 female), with a median age of 50 y [23-75]. Most frequent histotypes were: myxoid liposarcoma (18, 36.7%), leiomyosarcomas (13, 26.5 %) and well-differentiated/dedifferentiated liposarcoma (9, 18%). WHO grade were 1 in 14 (29%), 2 in 19 (39%) and 3 in 5 (10%) pts respectively. Patients who had a maximum of 2, 3 or 4 therapeutic sequences (TS) with T (drug-holiday and rechallenge) were 41/49 ,7/49 and 1/49 respectively. Median number of cycles for 1, 2, 3 and 4 TS were 7 [3-21], 6 [2-30], 6 [2-9] and 6. Median total number of cycles was 15 [6-43]. Median duration of drug-holiday for 1, 2 and 3 TS were 11 [3-91], 7 [2-29] and 4 months [1-5]. Grade 3-4 toxicities incidence decreased with the number of TS (occurred in 36%, 29%, 14% and 0% of pts with 1, 2, 3 and 4 TS) as well as mean T dose per cycle (1.3 mg/m², 1.2 mg/m², 1.1 mg/m² and 1.1 mg/m² for TS 1, 2, 3, 4). Efficacy decreased with number of TS (Number of CR/PR/SD/PD were 1 (2%)/15 (31%)/33 (67%)/0 for TS1; 0/4 (8%)/29 (59%)/16 (3%) for TS2; 0/1 (14%)/2 (29%)/4 (57%) for TS3 and 0/0/0/1(100%) for TS4). Median overall survival was 5.0 y [2.7-7.3] since T introduction, and 1.5 y [0.1-4.8], 0.8 y [0.5-1.3] and 0.6 y following 2nd, 3rd and 4th T reintroduction respectively. Objective response after TS2 were seen in 4 cases of grade 1 sarcomas. Conclusions: Due to the lack of cumulative toxicities over time with T, its rechallenging in responding patients to T (no progression under T) have to be considered in advanced STS.

This study aimed to analyze changes in the plasma concentration of EGFR-mutated DNA occurring immediately after the start of therapy with EGFR tyrosine kinase inhibitors (TKIs). The study included 30 patients with EGFR mutation-driven non-small cell lung cancer (NSCLC).  Serial plasma samples were collected before intake of the first tablet and at 0.5, 1, 2, 3, 6, 12, 24, 36 and 48 hours after the start of the therapy. EGFR-mutated plasma DNA (EGFR+ ctDNA) was detectable at diagnosis in 25 out of 30 study participants. There were different patterns of changes of the amount of circulating tumor DNA, i.e., the consistent decline of ctDNA content, or continuing increase of the number of circulating EGFR mutant copies, or alternating spikes and drops in the ctDNA concentration. Correlation with the disease outcome was observed only for the measurement performed at 48 hours. Twelve (50%) out of 24 informative patients showed >25% reduction of the ctDNA content at 48 h time point; all these patients demonstrated disease control after 4 and 8-12 weeks of therapy. The remaining 12 individuals showed either stable content of circulating EGFR+ DNA (n = 5) or the elevation of ctDNA concentration (n = 7). 10 of 12 patients with elevated or stable ctDNA level achieved an objective response at 4 weeks, but only 5 of 10 evaluable patients still demonstrated disease control at 8-12 weeks (p = 0.014, when compared to the group with ctDNA decrease). The decline of the amount of circulating EGFR mutant copies also correlated with longer progression-free survival (PFS; 14.7 months vs. 8.5 months, p = 0.013). Conclusion: Monitoring of plasma EGFR-M+ concentration within the first hours of the TKI therapy may be used as an immediate predictor of tumor response to the treatment.

11507 Background: PD1 inhibition has shown limited activity in all comers clinical trials including patients with advanced soft-tissue sarcomas (STS). In the PEMBROSARC study, objective response rate, progression-free (PFS) and overall survival (OS) were respectively 2.1%, 1.4 and 7.1 months respectively (Toulmonde et al. Jama Oncol 2017). We have recently shown that the presence of tertiary lymphoid structures (TLS) may represent a biomarker to select patients who are more likely to benefit from immunotherapy (PetitPrez et al., Nature 2020). We report here the first clinical trial investigating the efficacy of PD1 inhibition in TLS-positive STS. Methods: PEMBROSARC is an open-label multicenter phase II study of pembrolizumab in combination with low-dose cyclophosphamide in pts with STS selected based on the presence of TLS. TLS status has been assessed centrally has previously described (PetitPrez et al., Nature 2020). Eligible patients received pembrolizumab 200mg IV q21 days and cyclophosphamide 50 mg BID 1week on, 1 week off. All patients had confirmed progressive disease at inclusion based on central review of two imaging performed at less than 6 months interval. The primary efficacy endpoint was 6-month non-progression (as per RECIST evaluation criteria v1.1). Based on the following hypotheses: 15% 6-month non-progression rate (H0), 40% acceptable 6-month non-progression rate (H1), 5% type I error rate, 90% power, a total of 29 assessable patients were necessary and 8 patients or more had to be progression-free at 6 months to reach the first endpoint. Results: 240 patients were screened for TLS status between September 2018 and January 2020 in 7 centers of the French Sarcoma Group. Among them, 48 were found to be TLS+ as per central review and 35 were included in the study. The three most frequent histological subtypes were: well-differentiated/dedifferentiated liposarcoma (n = 13); UPS (n = 6), and leiomyosarcoma (n = 4). 30 patients were eligible for efficacy. Of those, as per central imaging review, 13 patients (43.3%) had tumor shrinkage resulting in partial response in 8 patients (26.7%) and stable disease in 5 cases (16.7%). 10 patients had progressive disease. Twelve patients were progression-free at 6 months (40.0% 95%CI = [22.7 – 59.4]).Median PFS and OS were 4.1 months (95%CI, 1.4-9.6) and 14.5 months (95%CI, 8.5- 18.3 months), respectively. Conclusions: With an objective response and a 6-month non-progression rates of 26.7% and 40% respectively versus 2.1% and 4.2% in all comers, the PEMBROSARC study confirms that selection based on TLS status is an efficient approach to tailor immunotherapy in STS patients.

TPS11583 Background: Soft tissue sarcomas (STS) are rare malignancies with poor prognosis in the metastatic setting. Current standard therapy includes anthracycline based chemotherapy. Cabozantinib is a multikinase inhibitor that has demonstrated efficacy in solid tumors such as renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC). A phase II study of cabozantinib in advanced STS is underway. Cabozantinib in combination with immune checkpoint blockade has shown clinical benefit in several tumor types including HCC, RCC, non-small cell lung cancer, and urothelial carcinoma. Since cabozantinib may alter PD-1 expression in regulatory T-cells and promote an immune permissive environment, we hypothesize that combining cabozantinib with immune checkpoint inhibition is a therapeutic strategy that will be more effective than cabozantinib alone. Additionally, the design of the trial will allow assessment of whether pretreatment with cabozantinib will enhance the efficacy of nivolumab and ipilimumab alone. Methods: This is an open label, multicenter, randomized phase II clinical trial of cabozantinib (60mg orally daily as a single agent, 40mg in combination) with or without combination Ipilimumab (ipi, 1mg/kg IV every 3 weeks for 4 doses) and Nivolumab (nivo, 3mg/kg IV every 3 weeks for four doses, then 480mg IV every 4 weeks) in patients (pts) with unresectable or metastatic STS refractory to up to two lines of chemotherapy. 105 pts with non-translocation driven sarcomas will be enrolled at three US sites and randomized 2:1 to the combination group. Pts will be stratified by prior pazopanib use and balanced for histologies. Patients who progress on arm A will cross over to combination therapy (arm B). The primary efficacy endpoint is objective response rate (ORR) by RECIST 1.1. 35 patients in Cohort A (cabozantinib alone) and 70 patients in Cohort B (cabozantinib plus ipi/nivo) will be required to detect an increase of the ORR from 10% in cohort A to 30% in cohort B with 81% power with a one-sided alpha level of 10%. Key eligibility criteria include: at least 18 years of age, ECOG performance status of 0 or 1, ≤2 prior lines of therapy and measurable disease. Exclusion criteria include: translocation-driven sarcoma except alveolar soft part sarcoma (ASPS), prior immunotherapy, and chronic use of corticosteroids or other immunosuppression. Secondary endpoints are safety, overall and progression free survival, disease control rate, and response rate to ipilimumab and nivolumab after cabozantinib pretreatment. Mandatory tumor biopsies pre-treatment and at 6 weeks will be obtained. Peripheral blood will be collected for circulating immune phenotyping. Enrollment will occur at 3 participating institutions and is expected to be completed in 2022. Clinical trial information: NCT04551430.

Dolastatin 10

Patients:Soft tissue sarcomas are uncommon malignancies with few therapeutic options for recurrent or metastatic disease. Dolastatin-10 (Dol-10) is a pentapeptide anti-microtubule agent that binds to tubulin sites distinct from vinca alkaloids. Based on the novel mechanism of action, limited activity of other anti-microtubular agents, and anti-neoplastic activity in pre-clinical screening of Dol-10, this multi-institutional phase II study was conducted to determine the objective response rate of Dol-10 in recurrent or metastatic soft tissue sarcomas that had not been treated with chemotherapy outside of the adjuvant setting.Methods:Dol-10 was given intravenously at a dose of 400 μg/m2and repeated every 21 days. Toxicities were assessed using the Common Toxicity Criteria (version 2.0). Radiographic studies and tumor measurements were repeated every two cycles to assess response [Miller AB, et al.Cancer1981; 47(1): 207].Results:Dol-10 was associated with hematological toxicity and with some vascular toxicities. There was no significant gastrointestinal, hepatic or renal toxicity. There was one death on study due to respiratory failure. There were no objective responses in 12 patients treated with Dol-10.Discussion:Based on this phase II trial, further study of Dol-10 on this schedule is not recommended in advanced or metastatic soft tissue sarcomas.
