5564 Background: Cabozantinib (C) may enhance response to immune checkpoint inhibitors (ICIs) by promoting an immune-permissive microenvironment and has shown encouraging activity in combination with ICIs in tumor types including RCC and HCC. C and atezolizumab (A) have shown low objective response rates as monotherapy in metastatic castration-resistant prostate cancer (mCRPC) (Smith JCO 2012; Kim JCO 2018). COSMIC-021 (NCT03170960), a multinational phase 1b study, is evaluating the combination of C + A in various solid tumors. We report results for Cohort 6 in mCRPC. Methods: Eligible patients (pts) were required to have radiographic progression in soft tissue after enzalutamide and/or abiraterone, measurable disease, and an ECOG PS of 0 or 1. Prior chemotherapy for mCSPC was permitted. Pts received C 40 mg PO QD and A 1200 mg IV Q3W. CT/MRI scans were performed Q6W for the first year and Q12W thereafter. The primary endpoint is ORR per RECIST 1.1. Other endpoints include safety, ORR per irRECIST, duration of response (DOR), PFS, and OS. Results are presented for the first 44 pts enrolled. Results: Median follow-up as of Dec 20, 2019 was 12.6 mo (range 5, 20) for the 44 mCRPC pts. Median age was 70 y (range 49, 90), 50% had ECOG PS 1, 34% had visceral metastases, and 61% had extrapelvic lymph node metastases. 27% had prior docetaxel and 52% had 2 prior novel hormonal therapies. The most common any grade treatment-related adverse events (TRAEs) were fatigue (50%), nausea (43%), decreased appetite (39%), diarrhea (39%), dysgeusia (34%), and PPE (32%). One grade 5 TRAE of dehydration was reported in a 90 y/o. Median duration of treatment was 6.3 mo. ORR per RECIST 1.1 among all 44 pts was 32% (2 CRs [4.5%] and 12 PRs [27%]); 21 (48%) pts had SD resulting in a disease control rate of 80% in all pts. One pt with PD per RECIST 1.1 had an irPR per irRECIST. ORR per RECIST 1.1 was 33% in 36 pts with high-risk disease (visceral and/or extrapelvic lymph node metastases). Median DOR for all pts with response per RECIST 1.1 was 8.3 mo (range 2.8, 9.8+). 17 (50%) of 34 pts with post-baseline PSA evaluation had a decrease in PSA. In 12 responders with post-baseline PSA evaluation, 8 (67%) had a PSA decrease ≥50%. Tumor PD-L1 expression will also be reported. Conclusions: The combination of C + A had a tolerable safety profile and demonstrated clinically meaningful activity with durable responses in men with mCRPC. Given the encouraging activity in these pts, especially in those with high-risk disease, further evaluation of C + A in men with mCRPC is being pursued. Clinical trial information: NCT03170960 .

5582 Background: Patients that have previously failed radiotherapy for prostate cancer is usually limited to systemic therapy due to morbidity from salvage prostatectomy. We reviewed the outcomes following focal salvage ablative therapy with HIFU or cryotherapy within the UK’s HEAT and ICE registries. Methods: 356 consecutive patients underwent focal ablative treatment after initial radiation treatment failure (28/1/2004-1/10/2019, 194 (54.5%) underwent HIFU (posterior recurrence) and 162 (45.5%) underwent cryotherapy (mostly anterior or T3b). Primary outcome was failure-free survival (FFS) defined as no systemic therapy, whole-gland treatment, metastases or prostate cancer-specific death. Secondary outcomes were adverse events and overall survival. Results: Median (IQR) age was 69years (65-73) and PSA (IQR) was 4.0ng/ml (1-7-7.2). Overall median (IQR) follow-up was 41.3 months (21.4-58.5). Quadrant ablation was performed in 128 (36.0%), hemi-ablation performed in 64 (18.0%), hockey-stick in 5 (1.4%) and 159 (43.8%) had unknown ablative patterns. Due to histological or MRI proven recurrence/residual disease, 31 (8.7%) underwent further focal salvage re-treatment. FFS (95%CI) at 3 and 6 years were 81% (76-87%) and 75% (68-83%) respectively. Median (IQR) time to failure was 15.5 months (19.7). Overall survival (95%CI) at 3 and 6 years were 97% (95-100%) and 88% (81-96%) respectively. Prostate-specific mortality was 2.8%. Overall 3 (0.8%) patients were managed for fistula formation, 16 (4.5%) were treated for UTIs. Conclusions: Salvage focal ablative therapy for radio-recurrent prostate cancer is safe and provides good short to medium-term oncological control. The FORECAST study is awaited to further determine oncological outcomes in this cohort.

562 Background: Cyclin-Dependent Kinase 4/6 inhibitors (CDK4/6i) represent the standard I-II line for hormonal receptors positive/human epidermal growth factor receptor 2 negative metastatic breast cancer (MBC) patients. Metastases directed radiotherapy (RT) for these patients is commonly used with palliative or radical schedules during systemic treatment. Although encouraging preliminary results were published, there is still a lack of robust data on the safety concerning RT during CDK4/6i treatment. Methods: we analyzed at Our Institution 85 consecutive patients treated in I (n=47) and II line (n=38) for MBC with CDK4/6i between April 2017 and September 2019 (22 ribociclib, 63 palbociclib). Overall, 25 (29.4%) patients received metastases directed RT during CDK4/6i treatment, including 14 concomitant (16.5%) and 11 sequential (12.9%). Estimated CDK4/6i half-life is 26 and 30 hours for palbociclib and ribociclib, respectively. Five half-lives are required to reduce drug concentration by 95-97%; thus, we also analyzed CDK4/6i treatment as non-concomitant or sequential to RT. Main endpoints of our analysis were impact of RT on CDK4/6i dose reduction and discontinuation, overall adverse events rate (any grade and grade ≥2), and neutropenia grade ≥2 as per CTCAE scale version 5.0. Results: at a median follow up of 12 months (range 3-29), we observed a CDK4/6i dose reduction in 35 patients (41.2%) and 5 patients (5.9%) discontinued treatment due to adverse events; 82 patients (96.5%) experienced any grade of toxicity, 72 (84.7%) a grade ≥2 and 70 patients (82.4%) neutropenia grade ≥2. We did not observe significant difference in terms of CDK4/6i dose reduction or discontinuation, any grade or grade ≥2 toxicity, neutropenia grade ≥2 in the comparison between patients receiving RT versus no RT and between patients receiving concomitant RT versus sequential RT versus no-RT (Table). Conclusions: our results showed that the prescription of a metastases directed RT during treatment with a CDK4/6i as I-II line for MBC did not significantly impact on dose reduction or discontinuation caused by an exceeding in adverse event rate. Although these promising results, caution should be used and cooperative initiatives strongly encouraged. [Table: see text]

569 Background: Patient-reported outcomes (PROs) of cosmesis after breast-conserving therapy (BCT) are increasingly emphasized as meaningful treatment endpoints but little is known about the relationship between objective measures, mood, and PROs following radiation (XRT). We hypothesized that pre-XRT depression, assessed by Inventory of Depressive Symptomatology Self-Report (IDS-SR), would influence PROs of breast cosmesis 1-year post-XRT independent of objective measures of breast asymmetry. Methods: 98 women were enrolled on two prospective longitudinal studies of breast cosmesis. Percentage breast retraction assessment (pBRA) was used as an objective measure of breast asymmetry pre- and 1 year post-XRT. At the same time points, pBRA was measured and compared with two different PRO ratings of cosmetic outcome (0-10 scale): 1) happiness with cosmesis and 2) perceived differences in treated vs. untreated breast. We performed univariate and multivariate analysis to evaluate the relationship between PROs, pBRA, IDS-SR scores, clinical, tumor, and treatment characteristics. Results: Among subjects, 50% were African American. Mean age was 56.45 years. At 1 year, 65.3% of patients were happy with their cosmetic outcome (Score > 8) although 59.5% noted moderate to severe differences in the treated vs. untreated breast (Score < 6). Mean pBRA increased from 7.20 (SD 3.88) pre-XRT to 9.69 (SD 6.22) confirming more breast asymmetry 1-year post-XRT. Prior to XRT, 23% of patients had moderate-to-severe depression (IDS-SR scores > 26). In multivariate analyses, 1 year PROs of happiness with cosmetic outcome did not correlate with pBRA (p = 0.3) but were strongly correlated with pre and post-XRT depression (all p < 0.05). Patients were more likely to perceive differences in breast texture or asymmetry (i.e. lower PRO ratings of asymmetry) if they had higher pBRA measurements at 1 year (all p = 0.004). Neither pre- nor post- XRT depression were associated with specific PRO ratings of breast asymmetry in multivariate analysis. Conclusions: Our study suggests that PROs may not always reflect the effects of cancer treatment. For patients treated with BCT, baseline depression strongly influenced patient reported happiness with overall cosmetic outcome 1 year post-XRT. Perceived differences in the treated vs. untreated breast correlated with objective measures of breast asymmetry. Our data suggests that this PRO may be more indicative of treatment-related toxicities than patient ratings of overall satisfaction and happiness with cosmetic outcome.

Published: May 2020

574 Background: Omission of axillary surgery is appropriate in some patients with clinically node-negative (cN0), HR+ ESBC; however, there are no pre-operative tools to predict pathologic node positivity (pN+) in these women. We propose a clinically validated predictive model to inform treatment decisions regarding axillary evaluation. Methods: We constructed a cohort of adult women with ESBC (clinical T1/T2, N0, M0) diagnosed 2012-2016, who underwent lumpectomy or mastectomy and lymph node surgery without neoadjuvant therapy using the National Cancer Database breast cancer dataset. The dataset was non-randomly split into training (2012-2015) and testing (2016) for development and validation. Stepwise logistic regression was used to identify predictors of pathologic node positivity (pN0 vs pN+) in the training dataset. Potential predictors included: age, race, ethnicity, comorbidity score, histologic type, clinical T, ER positivity, PR positivity, HER2 positivity, and grade. Predictor variables required a bivariate p-value <0.30 to be entered into model, and an adjusted p-value <0.35 to stay in model. A partial score method was used to develop a lymph node prediction score (LNPS) by assigning a weighted value to each strong predictor variable (OR >1.5) and adding together the values for each included variable. LNPS was treated as a linear variable for prediction in validation dataset. Results: 423,068 women were included (2012-2015: 334,778; 2016: 88,290). Pathologic node positivity was 17% in 2012-2015 and 2016. All variables were included in the final stepwise model. Strong predictors were age, histologic type, clinical T, and grade. Scores ranged from 0-11. In the validation dataset, predicted pN+ by LNPS was very similar to actual pN+ (Table). A 1-point increase in LNPS was associated with a 3.3% increase in absolute risk of pN+. Conclusions: A novel lymph node prediction score can be used in HR+ cT1-T2 cN0 breast cancers to estimate the probability of pN+ and guide decisions regarding axillary surgical evaluation.

6032 Background: GLS-010 is a novel fully human anti-PD-1 mAb. Previous Phase I study exhibited favorable result of tolerance, preliminary efficacy and 240mg fixed dose q2w was selected as Recommended Phase II Dose (RP2D). This Phase II clinical trial is aimed to further evaluate the safety and anti-tumor activity of GLS-010 in patients with recurrent or metastatic cervical cancer. Methods: PD-L1 positive (combined positive score (CPS) ≥1) patients with recurrent or metastatic cervical cancer who had received one or more lines of chemotherapy were enrolled and received GLS-010 240mg every 2 weeks. Primary endpoint was the objective response rate (ORR) per RECIST 1.1, secondary endpoints included duration of response (DoR) and safety. Results: From May 16th 2019 to December 24th 2019, 44 pts were enrolled and treated in the study. As of December 24th 2019,the median line of prior systemic chemotherapy was 2(range: 1~4), and 59% (26/44) of pts had received ≥2 previous lines of chemotherapy. The median number of GLS-010 doses was 1.5(range: 1~4). 25 pts received response evaluation per investigator review. With a median follow-up of 2.9 months, 7 of 25 evaluable pts achieved a partial response (PR). The ORR was 28% (95% CI, 12.07-49.39), with 7 pts achieving a PR ( 3 of 7 confirmed), 3 pts achieving stable disease (SD) and 15 pts with progressive disease (PD), 1 of which was assessed as dissociated response with treatment ongoing. Median duration of response had not been reached yet. 33 of 44 patients (75%) experienced one or more treatment-related adverse events (TRAEs) per NCI CTCAE v4.03, most of which were grade 1 or 2. The most common TRAEs were Anaemia (15/44), and 73.3% of them were grade 1 or 2. The most common ≥grade 3 TRAE included Anaemia (4/44). As data cut off, only 1 pt discontinued treatment due to adverse event. Conclusions: GLS-010 showed impressive therapeutic activity and manageable safety profile in Chinese recurrent or metastatic cervical cancer patients. Current evidence support further development of GLS-010 in this and more indications. This trial is still ongoing, and we are looking forward to further results.

Anlotinib in patients with recurrent advanced cervical cancer: A prospective single-arm, open-label, phase Ⅱ trial.
Authors: Wu Xiaohua , Zhu Jun 
Published: May 2020

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.

6042 Background: Ovarian clear cell carcinoma (OCCC) is a distinct entity from other epithelial ovarian cancers such as the most prevalent high-grade serous cancer (HGSC), and often exhibit less sensitivity to platinum-based chemotherapy. Several studies using cell lines have reported that glutathione (GSH) metabolism plays an important role in chemo-resistance of OCCC. Here, we aimed to correlate the prognosis of OCCC and the expression of gamma-glutamyltransferase 1 (GGT1), one of the key enzymes in GSH metabolism. Methods: We prepared a FFPE-tissue microarray, and analyzed 56 OCCC patients with the follow-up periods over 3 years. Expression level of GGT1 was evaluated by immunohistochemistry (IHC) using H-score (0-300), and was correlated with clinical outcomes. The prognostic significance was assessed by multivariate analysis using Cox regression model. To investigate the possible related pathways, we performed transcriptome analysis using Ion AmpliSeq Transcriptome Human Gene Expression Kit (Thermo Fisher Scientific) from the frozen tissue specimens collected from 33 ovarian cancer patients including 15 OCCC patients and 18 HGSC patients. Results: The OCCC patients were divided into two populations in the histogram of H-score in IHC staining, and the cut-off value was 90; 44 cases showed GGT1-high, and remaining 12 cases were GGT1-low. Follow-up periods, FIGO stage, and optimal surgery rate were not significantly different between two groups. However, platinum-resistant recurrent rate was significantly higher (42% vs. 14%, p=0.027), and overall survival (OS) was significantly shorter (5-year OS; 42% vs. 72%, p=0.0226) in GGT1-low OCCC. Multivariate analysis revealed that low expression of GGT1 was one of the independent poor prognostic factors as well as platinum-drug resistance. In enrichment analysis, the genes related to GSH metabolism, such as SLC3A1, GGT1, CSE, and GPX3 were up-regulated and positively correlated with HNF1B expression in OCCC. The expression level of GGT1 was inversely correlated with that of immune suppressive genes (TGF-b, IFNG, IL10, FOXP3, PD-L1, CTLA4) and epithelial-mesenchymal transition (EMT)-related genes (CDH2, VIM, TWIST1, ZEB1, ZEB2) in OCCC samples. Conclusions: Low expression of GGT1 is an independent poor prognostic factor probably in part due to suppression of tumor immunity and induction of EMT in OCCC.

6045 Background: Single agent immunotherapy (IO) has shown only modest clinical activity for the treatment of ovarian cancer. The combination of anti-programmed death-1 and PARP inhibitors showed promising activity in early trials. Here, we report the results of an open-label, parallel arm, dose escalation study of tremelimumab (T) alone or in combination with olaparib (O) in patients (pts) with advanced epithelial ovarian cancer (EOC). Methods: Pts with recurrent/persistent EOC who had progression < 12 months from last platinum exposure were enrolled. Prior therapy with IO (except anti-CTLA-4) or PARP inhibitor was allowed. Pts were randomized to either T 10mg/kg every 4 weeks (wks) x 7 then every 12 wks (Arm A) or T with O twice daily at three planned dose levels (Arm B). The primary objectives were safety, pharmacodynamic (PD) change in CD4+ICOShi peripheral T cells by flow cytometry, and identification of the optimal dose combination of T with O. Secondary objectives included 6-month progression-free survival (PFS6) and objective response rate (ORR). Results: A total of 24 pts were treated, 12 on Arm A, and 12 on two Arm B dose levels. Pts had a median age of 60 years (range 44-81). Histologic subtypes included high-grade serous EOC (20 pts, 83%), clear cell (3 pts, 13%), and moderately-differentiated adenocarcinoma (1 pt, 4%). BRCA1 mutation (mt) was present in 2 cases, BRCA2 mt in 1. Median number of prior regimens was 3.5 (range 1-9). Most adverse events (AEs) were attributable to T, the most common grade 3 toxicities were rash (13%), immune-mediated hepatitis (8%), and colitis (8%). No grade ≥4 toxicities were identified. Immune-mediated AEs also included acute kidney injury, hypophysitis, and hypothyroidism. No dose limiting toxicities were identified on Arm B. Two pts in Arm B had >PFS6. Of 20 pts evaluable for response, there was 1 partial response (Arm B), and 9 pts had stable disease (6 on Arm A, 3 on Arm B). Mean percentage of CD4+ICOShi T cells was significantly increased on Days 15 and 22 compared to Day 1 at both T dose levels (Table).T at 3 mg/kg with O at 150mg is the optimal dose of those tested. Conclusions: T and T with O was tolerable, with modest clinical activity in this pt population. AEs were as expected, and peripheral CD4+ICOShi T cells increased on therapy.
