    Abstract: Camrelizumab, an mAb against programmed cell death protein 1 (PD-1), plus nab-paclitaxel exhibited promising antitumor activity in refractory metastatic immunomodulatory triple-negative breast cancer (TNBC). Famitinib is a tyrosine kinase inhibitor targeting VEGFR2, PDGFR, and c-kit. We aimed to assess the efficacy and safety of a novel combination of famitinib, camrelizumab, and nab-paclitaxel in advanced immunomodulatory TNBC. Patients and Methods: This open-label, single-arm, phase II study enrolled patients with previously untreated, advanced, immunomodulatory TNBC (CD8 IHC staining ≥10%). Eligible patients received 20 mg of oral famitinib on days 1 to 28, 200 mg of i.v. camrelizumab on days 1 and 15, and i.v. nab-paclitaxel 100 mg/m2 on days 1, 8, and 15 in 4-week cycles. The primary endpoint was objective response rate (ORR), as assessed by investigators per RECIST v1.1. Key secondary endpoints were progression-free survival (PFS), overall survival (OS), duration of response (DOR), safety, and exploratory biomarkers. Results: Forty-eight patients were enrolled and treated. Median follow-up was 17.0 months (range, 8.7–24.3). Confirmed ORR was 81.3% [95% confidence interval (CI), 70.2–92.3], with five complete and 34 partial responses. Median PFS was 13.6 months (95% CI, 8.4–18.8), and median DOR was 14.9 months [95% CI, not estimable (NE)–NE] . Median OS was not reached. No treatment-related deaths were reported. Among 30 patients with IHC, 13 (43.3%) were programmed death-ligand 1 (PD-L1)–negative, and PD-L1 was associated with favorable response. PKD1 and KAT6A somatic mutations were associated with therapy response. Conclusions: The triplet regimen was efficacious and well tolerated in previously untreated, advanced, immunomodulatory TNBC. The randomized controlled FUTURE-SUPER trial is under way to validate our findings. See related commentary by Salgado and Loi, p. 2728

    ARRB1-Promoted NOTCH1 Degradation Is Suppressed by OncomiR miR-223 in T-cell Acute Lymphoblastic Leukemia
    American Association for Cancer Research (AACR) ; 2020

    Abstract: T-cell acute lymphoblastic leukemia (T-ALL) is a type of aggressive leukemia with inferior prognosis. Although activating mutations of NOTCH1 are observed in most T-ALL cases, these mutations alone are not sufficient to drive the full development of T-ALL. β-Arrestins (ARRB) are versatile and multifunctional adapter proteins that regulate diverse cellular functions, including promoting the development of cancer. However, the role of ARRBs in T-ALL has largely remained elusive. In this study, we showed that ARRB1 is expressed at low levels in assayed T-ALL clinical samples and cell lines. Exogenous ARRB1 expression inhibited T-ALL proliferation and improved the survival of T-ALL xenograft animals. ARRB1 facilitated NOTCH1 ubiquitination and degradation through interactions with NOTCH1 and DTX1. Mechanistically, the oncogenic miRNA (oncomiR) miR-223 targets the 3′-UTR of ARRB1 (BUTR) and inhibits its expression in T-ALL. Furthermore, overexpression of the ARRB1-derived miR-223 sponge suppressed T-ALL cell proliferation and induced apoptosis. Collectively, these results demonstrate that ARRB1 acts as a tumor suppressor in T-ALL by promoting NOTCH1 degradation, which is inhibited by elevated miR-223, suggesting that ARRB1 may serve as a valid drug target in the development of novel T-ALL therapeutics. Significance: These findings highlight a novel tumor suppressive function of the adaptor protein β-arrestin1 in T-ALL.

    Tislelizumab for Relapsed/Refractory Classical Hodgkin Lymphoma: 3-Year Follow-up and Correlative Biomarker Analysis
    American Association for Cancer Research (AACR) ; 2022

    Abstract: Tislelizumab is an anti–programmed cell death protein 1 (anti–PD-1) monoclonal antibody specifically designed to minimize binding to Fcγ receptors (FcγR). Patients and Methods: Here, we present the extended 3-year follow-up of a phase II study of tislelizumab in 70 patients with relapsed/refractory classical Hodgkin lymphoma (cHL) who failed or were ineligible for autologous stem cell transplantation. Results: With a median follow-up of 33.8 months, the overall response rate by the independent review committee was 87.1%, and the complete response (CR) rate was 67.1%. Responses were durable as shown by a median duration of response of 31.3 months, and median progression-free survival (PFS) of 31.5 months. The 3-year PFS and overall survival rates were 40.8% and 84.8%, respectively. Treatment-related adverse events (TRAEs) of any grade occurred in 97.1% of patients; the grade ≥3 TRAE rate was low (31.4%), and only 8.6% of patients experienced adverse events leading to treatment discontinuation. Correlative biomarker analysis showed that FcγRΙ-expressing macrophages had no observed impact on either the CR rate or PFS achieved with tislelizumab, which may be potentially related to its engineered Fc region. Conclusions: With extended follow-up, tislelizumab yielded long-term benefits and demonstrated a favorable safety profile for patients with relapsed/refractory cHL. This trial was registered at clinicaltrials.gov as NCT03209973.

    Abstract: Mantle-cell lymphoma (MCL) is an incurable mature B-cell neoplasm with high initial response rates followed almost invariably by relapse. Prognosis for patients following relapse is poor, and treatment choices are limited. We evaluated the efficacy and safety of zanubrutinib, an investigational selective Bruton's tyrosine kinase (BTK) inhibitor. Patients and Methods: Patients with relapsed/refractory MCL were enrolled in this ongoing phase II, single-arm, open-label study, and treated with oral zanubrutinib 160 mg twice daily. The primary endpoint is overall response rate (ORR) assessed by an independent review committee (per Lugano 2014 classification); secondary endpoints include duration of response (DOR), time to response, progression-free survival (PFS), and safety. Results: Eighty-six patients (median age, 60.5 years) were enrolled after a median of 2 prior lines of therapy, received ≥1 dose of the study drug, and were evaluable for safety and efficacy. After a median follow-up of 18.4 months, 72 (84%) patients achieved an objective response, with 59 (68.6%) achieving a complete response (CR). Median DOR and PFS were 19.5 and 22.1 months, respectively; 12-month event-free estimates for DOR and PFS are 78% and 76%, respectively. Most common grade ≥3 adverse events (AE) were neutropenia (19.8%) and lung infection/pneumonia (9.3%). Three patients experienced major bleeding events, and there were no reports of atrial fibrillation. Eight (9.3%) patients discontinued zanubrutinib for AEs. Conclusions: These results demonstrate high and durable ORR and CR rates in patients with relapsed/refractory MCL. Zanubrutinib was generally well tolerated; grade ≥3 BTK inhibitor-associated toxicities (hemorrhage, rash, hypertension, diarrhea, atrial fibrillation) were uncommon.
