Abstract We evaluated the efficacy and safety of trifluridine/tipiracil (TAS-102) plus bevacizumab in treating refractory metastatic colorectal cancer (mCRC) in a retrospective, observational study. Patients refractory or intolerant to standard therapies received TAS-102 (30–35 mg/m2 twice daily on days 1–5 and days 8–12 every 28 days) plus bevacizumab 5 mg/kg on days 1 and 15. Clinical and pathological characteristics, overall response rate (ORR) and disease control rate (DCR), overall survival (OS) and progression-free survival (PFS) data were collected and analysed. Thirty-five patients were treated from July 2019 to October 2021 (median age 64 years). The majority of patients (68.6%) were receiving TAS-102 plus bevacizumab as third-line treatment. Patients received a median of 4 (range 2–15) cycles of treatment. Among 31 patients evaluable for response (88.6%), ORR and DCR were 3.2% and 51.6%, respectively. After a median 11.6 months’ follow-up, median PFS was 4.3 (95% confidence interval [CI] 3.4–5.1) months and median OS was 9.3 (95% CI 6.6–12.1) months. The most common grade 3–4 toxicities were neutropenia, asthenia and nausea/vomiting, and there were no treatment-related deaths. This real-world study confirms the efficacy and safety of TAS-102 plus bevacizumab in patients with refractory mCRC.

Abstract Background There is increasing evidence that combination therapy with nanoparticle albumin-bound paclitaxel (nab-paclitaxel) and programmed cell death protein 1 (PD-1) inhibitor is safe and efficacious in treating many types of malignant tumors. However, clinical data demonstrating the effect of this treatment combination for patients with metastatic soft tissue sarcoma (STS) are currently limited. Methods The clinical data of patients with metastatic STS who received nab-paclitaxel plus PD-1 inhibitor (sintilimab) therapy between January 2019 and February 2021 were retrospectively analyzed. The effectiveness and safety of the combined treatment were evaluated in terms of the median progression-free survival (PFS), estimated using the Kaplan–Meier method. The univariate Cox proportional hazards model was used to analyze the relationship between clinicopathological parameters and PFS. All statistical analyses were two-sided; P < 0.05 was considered statistically significant. Results A total of 28 patients treated with nab-paclitaxel plus sintilimab were enrolled in this study. The objective response rate was 25%, the disease control rate was 50%, and the median PFS was 2.25 months (95% CI = 1.8–3.0 months). The most common grade 1 or 2 adverse events (AEs) were alopecia (89.3%; 25/28), leukopenia (25.0%; 7/28), fatigue (21.4%; 6/28), anemia (21.4%; 6/28), and nausea (21.4%; 6/28). The most common grade 3 AEs were neutropenia (10.7%; 3/28) and peripheral neuropathy (10.7%; 3/28). No grade 4 AEs were observed. Among the present study cohort, patients with angiosarcoma (n = 5) had significantly longer PFS (P = 0.012) than patients with other pathological subtypes, including undifferentiated pleomorphic sarcoma (n = 7), epithelioid sarcoma (n = 5), fibrosarcoma (n = 4), synovial sarcoma (n = 3), leiomyosarcoma (n = 2), pleomorphic liposarcoma (n = 1), and rhabdomyosarcoma (n = 1); those who experienced three or more AEs had significantly longer median PFS than those who experienced less than three AEs (P = 0.018). Conclusion Nab-paclitaxel plus PD-1 inhibitor is a promising treatment regimen for advanced STS. Randomized controlled clinical trials are required to further demonstrate its efficacy and optimal application scenario.

Grading practices at Dalhousie University have changed considerably over the past 120 years. From 1901 until the early 1970s, Dalhousie used a variant of the British system. Initially, a grade of 65% or higher was required for distinction. In 1937, Dalhousie moved to a 2-category system (Distinction vs. Ordinary Pass) and in 1942 the distinction grade cutoff was lowered to 60%. By the late 1940s, the British system returns, “Second Division” was subdivided into Seconds and Thirds, and First Division required an 80% or higher. By the late 1960s, there were conversions between American letter grades (A, B, C, D), divisions, and percentage grades. Moreover, there was a 4pt “merit point” system that served as a prototype to Grade Point Averages (GPA). Experimental teaching and grading practices were explored in the 1970s. Officially, percentage grades were abolished and replaced with an 11-point letter grade scale from A+ to F. Unofficially, most professors and departments continued to use percentage-to-letter conversion schemes that were highly idiosyncratic, though they were eventually standardized within (but not across) departments. In the 1990s, the 4.3 GPA system was standardized university-wide largely because it was thought to give students a competitive advantage for federal scholarships. In the 2010s, Dalhousie standardized percentage conversion schemes across all departments into one unified Common Grade Scale, partially due to GPA requirements for scholarships and graduate schools. Overall, most grading changes in the past 120 years were implemented for the external communication value of grades rather than for their pedagogical value.

AbstractSelinexor, an oral selective inhibitor of nuclear export (SINE), was demonstrated to hinder the DNA damage repair (DDR) system by reducing DDR proteins while enhancing the killing of cancer cells by DDR-based therapeutics in vivo studies. In this single-center, multi-arm phase 1b study, selinexor with carboplatin, doxorubicin and cyclophosphamide (DC), irinotecan with fluorouracil and folinic acid (FOLFIRI), irinotecan, and capecitabine and oxaliplatin (XELOX), were employed as separate parallel arms. Eligible patients have relapsed/ metastatic refractory solid tumors following standard therapy or addition of selinexor to systemic therapy was appropriate. Nineteen patients were treated in the 5 arms. Tumor types included were colorectal (n  = 3), breast (n  = 3), neuroendocrine (n  = 2), ovarian (n  = 2), and pancreas cancers (n  = 2). All patients developed one treatment-related adverse events (TRAE). The most prevalent TRAE were thrombocytopenia (84%), nausea (68%), leukopenia (68%), neutropenia (63%), and fatigue (58%). The common grade 3/4 TRAE were neutropenia (42%), leukopenia (26%), and hyponatremia (21%). Three patients had dose-limiting toxicities (DLT) in 3 separate arms. Fourteen patients were evaluable for response. Although no patients achieved complete or partial response (CR or PR), seven patients attained stable disease (SD). Disease control rate (DCR) was 14%. The combination of oral selinexor with different standard chemotherapies showed limited clinical activity despite toxicity and DLT prevented further dose escalation. Optimizing supportive care, the utility of growth factors, and aggressive measures on antiemetics strategies remain tangible.Trial registration ClinicalTrials.gov Identifier: NCT02419495.

AbstractTalimogene laherparepvec (T-VEC) is an immunotherapy that generates local tumor lysis and systemic antitumor immune response. We studied the efficacy of intratumoral administration of T-VEC as monotherapy for inoperable locoregional recurrence of breast cancer. T-VEC was injected intratumorally at 106 PFU/mL on day 1 (cycle 1), 108 PFU/mL on day 22 (cycle 2), and 108 PFU/mL every 2 weeks thereafter (cycles ≥ 3). Nine patients were enrolled, 6 with only locoregional disease and 3 with both locoregional and distant disease. No patient completed the planned 10 cycles or achieved complete or partial response. The median number of cycles administered was 4 (range, 3–8). Seven patients withdrew prematurely because of uncontrolled disease progression, 1 withdrew after cycle 3 because of fatigue, and 1 withdrew after cycle 4 for reasons unrelated to study treatment. Median progression-free survival and overall survival were 77 days (95% CI, 63–NA) and 361 days (95% CI, 240–NA). Two patients received 8 cycles with clinically stable disease as the best response. The most common grade 2 or higher adverse event was injection site reaction (n = 7, 78%). Future studies could examine whether combining intratumoral T-VEC with concurrent systemic therapy produces better outcomes.

Abstract Background To our knowledge, there is no clinical data pertaining to COVID-19 outcomes and safety of COVID-19 vaccination in Russian patients with genitourinary (GU) malignancies. Aim of our analysis was to describe the characteristics of the COVID-19 infection course as well as preliminary safety and efficacy of Gam-COVID-Vac vaccine in patients with active GU malignancies. Methods Patients were retrospectively identified at nine cancer centers in different regions. Patients were included if COVID-19 was diagnosed by a polymerase chain reaction. Data from additional patients with GU cancers who had no positive SARS-CoV-2 RT-PCR test before vaccination and who received two doses of Gam-COVID-Vac (Sputnik V) between 11 February and 31 August 2021 were collected for safety assessment. Anonymized data were collected through an online registry covering demographics, treatments, and outcomes. Results The Gam-COVID-Vac vaccine was well tolerated; no grade 3–5 toxicities were reported in 112 vaccinated metastatic GU cancer patients. The most common grade 1 adverse events (81%) were injection site reactions (76%), flu-like illness (68%), and asthenia (49%). Five patients experienced grade 2 chills (4.5%) and 3 patients had grade 2 fever (2.7%). With median follow-up of 6.2 months, two COVID-19 cases were confirmed by RT-PCR test in the vaccine group (of 112 participants; 1.8%). Eighty-eight patients with COVID-19 disease were included in the analysis. The average age as of the study enrollment was 66 (range 39–81) and the majority of patients were male with renal cell carcinoma (RCC). Thirty-six patients (41%) had evidence of metastatic disease, of these 22 patients were receiving systemic therapy. More than half of patients required hospitalization. Fifty-four patients (61%) experienced complications. Sixteen patients who developed COVID-19 pneumonia required mechanical ventilator support. Sixteen patients (18%) died in a median of 23.5 days after the date of COVID-19 diagnosis was established. The 3-month survival rate was 82%. Clinical and/or radiographic progression of cancer during COVID-19 infection or the subsequent 3 months was observed in 10 patients (11.4%). Conclusion Patients with GU malignancies are at increased risk of mortality from COVID-19 infection when compared to the general population. Vaccination could be safe in GU cancer patients. Trial registration: retrospectively registered.

Abstract Background: T-cell lymphomas constitute heterogeneous subtypes of non-Hodgkin lymphoma (NHL). With the exception of brentuximab (BV) with cyclophosphamide, adriamycin, prednisone (CHP) in anaplastic large cell lymphoma (ALCL) establishing a standard of care in this subtype, the choice of first-line therapy in other subtypes are based on CHOP like regimens with or without etoposide. Few studies have evaluated the efficacy of etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (EPOCH) in patients with aggressive T-cell lymphomas. We report our single center experience in patients receiving EPOCH in frontline or relapsed/refractory (R/R) setting for aggressive T-cell lymphomas including transformed cutaneous T-cell lymphomas (CTCL). Methods:Adult patients with aggressive T-cell lymphomas who received EPOCH from May 2015 to October 2020 at Yale-New Haven Hospital were included in this analysis. Adverse effects were graded per the CTCAE criteria. Statistical analyses were performed using STATA 14.2. The primary objective was to determine the efficacy of EPOCH in terms of response rates and survival outcome. The secondary objective was to determine toxicity rates. Results: Thirty-eight patients with aggressive T-cell lymphomas were included in the study. This included angioimmunoblastic T-cell lymphoma (AITL) (n=7), adult T-cell leukemia/lymphoma (ATLL) (n=9), ALCL (n=2), peripheral T-cell lymphoma - not otherwise specified (PTCL-NOS) (n=7), T follicular helper (Tfh) subtype (n=1), subcutaneous panniculitis-like T-cell lymphoma (SPTCL) (n=1) and CTCL (n=11). Eighteen patients received EPOCH in the first line and 21 patients in R/R setting. The overall response rate (ORR) for the entire cohort was 77% and complete response (CR) rate was 51%. The CR rate in the frontline was 60% and in R/R setting was 45%. At a median follow up of 22.1 months (95% CI: 17.3 to 28.4), the median progression free survival (PFS) was 7.8 months (95% CI 4.3 to 9.8), and median overall survival (OS) was 19.7 months (12.1 to NR). Fifteen patients went onto allogeneic stem cell transplant after remission with EPOCH. The most common grade 3 adverse effects were anemia (63%), thrombocytopenia (34%), and neutropenia (32%). The most common grade 4 adverse effects were neutropenia (71%) and thrombocytopenia (39%). Discussion: This study reports the efficacy and safety results of EPOCH in T-cell lymphoma both in the first line in R/R setting.We found that EPOCH has excellent response rates and good tolerability in T-cell lymphomas. With CR rates of &gt;50%, EPOCH is a promising backbone for combination trials in aggressive T-cell lymphomas targeting deep responses prior to consolidation with transplant. Our study is unique in including CTCL patients who required treatment with combination chemotherapy due to an aggressive clinical course and/or large cell transformation.

Abstract Background: Indolent B-cell lymphoma (iBCL) are clinically heterogeneous and accounts for 10-15% of all kind of subtypes in NHL in China. Although iBCL have a relatively good survival, majority of these lymphomas is considered incurable. The favorable activity and safety profile of rituximab monotherapy in the initial treatment of iBCL has been proven. Interferon alpha (IFN-α) has been proven to be effective in modulating immune responses and may enhance the clinical responses to rituximab in vitro and in vivo studies. Clinical combination of rituximab and IFN-α was associated with fewer early treatment failures compared to single agent rituximab. Peginterferon-α-2(peg-IFN-α2) has a longer half-life with less toxicity. It also is one of the options for the treatment of chronic hepatitis B virus (CHB) infection. Therefore, we hypothesized that peg-IFN-α2 may synergize with rituximab and would minimize or eliminate minimal residual disease (MRD). The purpose of this study is to evaluate the efficacy and safety for this combination in pts(pts) with treatment-naive iBCL. Methods: This trial enrolled eligible pts aged 18-80 years with newly diagnosed iBCL including FL(grade 1-2,3a) and MZL. Pts were eligible if they had ECOG ≤ 2, adequate organ function and bone marrow function, and at least one measurable or evaluable lesion. Further eligibility criteria were HBsAg positivity with HBV DNA load &lt;3000 IU/mL prior to study; serum ALT level of &lt;5 times the upper limit of normal. During induction phase, pts received rituximab biosimilar (Henliritux ® Shanghai Henlius Biotech) 375 mg/m 2 intravenous infusion on d1. Peg-IFN-α2b (Pegberon ®, Xiamen Amoytop Biotech) was given at a dose of 135ug, subcutaneously, on d1,8. The combination repeated every 21 days for 6 cycles. Responded pts receive rituximab (every 2 months) plus peg-IFN-α2b (every month) maintenance at the dose described above, for up to 2 years until disease progression and intolerance. Simultaneously, CHB pts orally treated with entecavir continuously. The primary endpoint is ORR assessed by investigators per Lugano 2014 criteria. Key secondary endpoints included TTR, DOR, PFS, OS, HBV DNA load clearance, and safety. Adverse events (AEs) were summarized according to NCI CTCAE v5.0. All pts' blood samples were collected for circulating tumor DNA (ctDNA) assessment before treatment in each of cycles. ctDNA samples were analyzed by capture-based NGS targeting 475 lymphoma- and cancer- relevant genes. This trial was registered at ClinicalTrials.gov (NCT04246359). Results: From January 2020 to July 2021, 52 eligible pts with median age of 54 (range, 29-75) years were enrolled from 6 institutions in China. Thirty (54.5%) are female, 20(36.4%) pts were symptomatic and 22(40.7%) pts with FLIPI score≥3, 6(10.9%) pts suffer from hepatitis B with HBV DNA load &lt;3000 IU/mL at study entry. At cutoff date, there were 25(46.3%) FL (grade 1-2), 19(35.2%) MALT, 8(14.8%) FL (grade 3a) pts enrolled. Of 50 response evaluable pts, 31(62.0%) pts achieved an objective response including 19(38.0%) pts with CR based on investigators. ORR were 58.3% (14/24), 75.0% (6/8), 61.1% (11/18) and the CR rates were 29.2% (7/24), 62.5% (5/8), 38.9% (7/18), 0,0 for FL (grade 1-2), FL (grade3a), MALT respectively. Median HBV DNA load clearance time was 1.8 months (1.3-2.1months), no hepatitis B virus reactivation reported. With median follow-up time was 6.2 months (range: 1.4-18.3 months), median OS, PFS and DoR was not reached; 6-month OS and PFS rate of whole cohort was 96.7±3.3%, 85.3±6.1%, respectively. Median TTR was 3.0months (1.5-5.2months). Dynamics ctDNA assay is in progress, data in detail will be reported at the ASH conference. The most common treatment-emergent adverse events (TEAEs) were hematological relevance toxicities. The most common grade hematological TEAEs (&gt;30%) were neutropenia 63.5%, anemia 34.6%, thrombocytopenia 28.8%. Non-hematological TEAEs (&gt;10%) were fever (28.8%), transaminase elevated (28.8%), fatigue (26.9%), infusion reaction (17.4%). Most common grade 3-4 TEAEs (&gt;5%) were neutropenia(17.3%), anemia (7.7%). No treatment-related death occurred. Conclusion: Rituximab biosimilar plus pegylated interferon α-2b provided favorable response in newly diagnosed advanced iBCL and was well tolerated. No hepatitis B virus reactivation was observed. Further investigation is warranted. Figure 1 Figure 1. Disclosures No relevant conflicts of interest to declare.

Abstract Background: ATG-010 (selinexor) is a novel, oral selective inhibitor of nuclear export, which blocks exportin 1. US FDA has approved selinexor plus low dose dexamethasone (Sd) to treat patients (pts) with penta-refractory MM based on the STORM study. MARCH is a single arm, Phase 2, registrational study to assess efficacy and safety of Sd in Chinese pts with RRMM. Methods: Enrolled Chinese pts were previously refractory to PI, IMiD, and last line of therapy. ATG-010 (80mg) plus dexamethasone (20mg) was administered twice weekly. The primary endpoint was overall response rate (ORR) per independent review committee. The planned 82 pts would provide ~80% power to test against null hypothesis (H 0) of 15% ORR at one-sided α of 0.025 at the primary analysis, which is presented here. Results: As of 6 th May 2021, 9 (11%) of the 82 pts were still on treatment. Median follow-up was 10.6 months (mo) (range: 2.3-19.6). Median age was 60 years (39% ≥ 65yrs). Median duration from MM initial diagnosis was 3.2 years. A total of 61 pts (74.4%) had cytogenetic abnormalities (del(17p): 22.0%), 18 (22.0%) with baseline plasmacytoma, and 18 (22.0%) with creatinine clearance &lt; 60ml/min. Median number of prior regimens were 5 (range 1-16); 23 pts (28.0%) had received daratumumab (triple-class exposure), 20 pts were triple-class refractory (TCR), and10 pts (12.2%) had undergone CAR-T therapy. ORR was 29.3% (95% CI: 19.7, 40.4), rejecting H 0, including 4 VGPR (very good partial response). Median duration of response (DOR) was 4.7 mo, median progression free survival (PFS) was 3.7 mo, and median overall survival (OS) was 13.2 mo. Among 20 TCR pts, ORR was 25.0% (95% CI:8.7, 49.1), mDOR 10.2 mo, mPFS 2.9 mo, and mOS 11.9 mo. Efficacy was evident in elderly pts (≥ 65yrs), with ORR 25% (95% CI: 11.5, 43.4) and mPFS 2.8 mo. Median OS and DOR were not reached. Sd also demonstrated a similar response rate in pts with high-risk cytogenetic abnormalities, with an ORR of 24.6% (95% CI: 14.5, 37.3). Efficacy of Sd was generally consistent across cytogenetic risk subgroups, including del (17p) pts with ORR 22.2% (95% CI: 6.4, 47.6), mDOR 3.8mo, and mPFS 2.9 mo. The most common non-hematologic treatment-emergent adverse events (TEAEs) of any grade included nausea (78%), hyponatremia (67.1%), weight loss (65.9%), decreased appetite (62.2%), asthenia (59.8%)/fatigue (15.9%), and vomiting (50.0%). The most common grade≥3 non-hematologic TEAE were hyponatremia (29.3%), pneumonia (26.8%), hypokalemia (12.2%) and asthenia (9.8%)/fatigue (2.4%). The most common grade≥3 hematologic TEAEs were anemia (57.3%), lymphopenia (76.8%), thrombocytopenia (51.2%), and neutropenia (40.2%). TESAE occurred in 54.9% of pts, with the most common being thrombocytopenia and pneumonia (14.6% each). TEAE led to death in 7 pts (8.5%). Elderly pts had no significantly increased risk of adverse events, however, given their limited physical state, drug exposure was shorter in the elderly subgroup (12.6 vs 16.1 weeks), suggesting more active supportive care is required. Conclusions: MM refractory to both IMiD and PI remains a high unmet medical need, especially in China. The MARCH study demonstrates statistically significant and clinically meaningful ORR with Sd in Chinese RRMM pts, and efficacy was consistent across subgroups, including the elderly and pts with high-risk cytogenetics. Adverse events were as expected and manageable with appropriate supportive care and dose modification. These data are compatible with the STORM study and offers a new, oral therapeutic option for MM patients. Disclosures Yu: Antengene Therapeutics Ltd.: Current Employment.

Abstract 【Abstract】 Objective: To investigate the efficacy and safety of BCL-2 inhibitor Venetoclax (Ven) 400mg combined with bortezomib and dexamethasone in plasma cell dyscrasia with t(11,14). Methods: The data of twenty patients with plasma cell dyscrasia with t (11;14) were retrospectively analyzed.The majority of patients received Venetoclax 400mg combined with bortezomib and dexamethasone. The baseline clinical information, treatment efficacy and adverse effects after Ven-based regimen. Results: Seventeen multiple myeloma patients, two light-chain amyloidosis and one primary plasma cell leukemia (pPCL) patients were studied. Among seventeen MM patients, the median follow-up was 9.0 (0.5-27) months and the median treatment cycles was 4 (1-12);fourteen patients have been evaluated for response rate. The overall response rate for evaluable patients (ORR) was 85.7%, among that one patient (7.1%) achieved CR, four patients (28.6%) achieved VGPR and 7 (50%) achieved PR. The median progression-free survival (PFS) was11.0 months (95%CI 2.1-19.9); the median Overall survival (OS) was 14.0 months (95%CI 6.9-21.1). Two amyloidosis patients achieved VGPR and PR respectively, while one pPCL patient achieved CR. The most common grade 3 or worse treatment-emergent adverse events were thrombocytopenia (15%), infection (10%), neutropenia (5%), diarrhea (5%) and peripheral neuropathy (5%). There was no treatment-related death. Conclusion Ven (400mg) combined with bortezomib and dexamethasone is feasible, tolerated and efficacious in plasma cell dyscrasia. 【Key words】Plasma cell dyscrasia; Venetoclax; Efficacy; Safety Disclosures No relevant conflicts of interest to declare.
