Tropical leaf phenology signals leaf-on/off status and exhibits strong variability from individual tree crowns to forest ecosystems, which importantly regulates carbon and water fluxes. The availability of daily PlanetScope data with high spatial resolution offers a new chance to monitor phenology variability at both the fine scale and the ecosystem scale across pan-tropics. However, a scalable method for tropical leaf phenology monitoring from PlanetScope with clear biophysical meaning still needs to be developed. To advance tropical leaf phenology monitoring, we developed an index-guided, ecologically constrained autoencoder (IG-ECAE) method to automatically generate a deciduousness metric (percentage of upper tree canopies with leaf-off status within an image pixel) from PlanetScope. The IG-ECAE includes three steps: (1) extracting the initial reflectance spectra of leafy/leafless canopies based on their spectral indices characteristics; (2) training an autoencoder deep learning method with the guidance of derived reflectance spectra and additional ecological constraints to refine the reflectance spectra; and (3) estimating the relative abundance of leafless canopies (or deciduousness) per PlanetScope image pixel with the integration of refined spectra reflectance and linear spectral unmixing method. To test the IG-ECAE method, we compared the PlanetScope-derived deciduousness to the corresponding measures derived from WorldView-2 (n = 9 sites) and local phenocams (n = 9 sites) at 16 tropical forest sites spanning multiple continents and a large precipitation gradient (1470-2819 mm year-1). Our results show that PlanetScope-derived deciduousness agrees: 1) with WorldView-2-derived deciduousness at the patch level (90 m × 90 m) with r2 = 0.89 across all sites; and 2) with phenocam-derived deciduousness to quantify ecosystem-scale seasonality with r2 ranging from 0.62 to 0.96. These results demonstrate that IG-ECAE can accurately characterize the wide variability in deciduousness across scales from pixels to forest ecosystems, and from a single date to the entire annual cycle, indicating the feasibility of tracking the large-scale phenological patterns and responses of tropical forests to climate change with high-resolution satellites.

Background: KTE-X19, an autologous anti-CD19 chimeric antigen receptor (CAR) T cell therapy, is currently being evaluated in patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) who received 1 - 5 prior therapies (including a Bruton tyrosine kinase inhibitor) in the Phase 2, registrational, multicenter ZUMA-2 study. With a median follow-up of 12.3 months, we previously reported an objective response rate (ORR) of 93% (67% complete response [CR] rate) with KTE-X19 treatment in the 60 efficacy-evaluable patients in ZUMA-2 (Wang et al. N Engl J Med. 2020;382:1331). Here, we present an updated analysis of efficacy, safety, and pharmacology for all patients with a minimum follow-up of 1 year. Methods: Eligible patients with R/R MCL underwent leukapheresis and conditioning chemotherapy followed by a single infusion of KTE-X19 (2 × 106 CAR T cells/kg; Wang et al. N Engl J Med. 2020;382:1331). The primary endpoint was ORR (CR + partial response) as assessed by an Independent Review Committee according to the Lugano Classification (Cheson et al. J Clin Oncol. 2014;32:3059). Efficacy data are reported for the 60 treated patients with ≥ 1 year of follow-up; safety data are presented for all 68 treated patients. Results: As of December 31, 2019, the median follow-up was 17.5 months (range, 12.3 - 37.6). The ORR was 92% (95% CI, 81.6 - 97.2), with a CR rate of 67% (95% CI, 53.3 - 78.3). Of all efficacy-evaluable patients, 48% had ongoing responses at the data cutoff. Medians were not reached for duration of response, progression-free survival (PFS), or overall survival; 15-month estimates were 58.6% (95% CI, 42.5 - 71.7), 59.2% (95% CI, 44.6 - 71.2), or 76.0% (95% CI, 62.8 - 85.1), respectively. In patients who achieved a CR, the median PFS was not reached (15-month rate, 75.1% [95% CI, 56.8 - 86.5]); in those who achieved a partial response, the median PFS was 3.1 months (95% CI, 2.3 - 5.2). Median PFS was 1.1 months (95% CI, 0.9 - 3.0) in nonresponding patients. The first 28 patients treated had a median follow-up of 32.3 months (range, 30.6 - 37.6); 39.3% of these patients remain in remission with no further therapy. Common grade ≥ 3 adverse events were neutropenia (85%), thrombocytopenia (53%), anemia (53%), and infections (34%). Grade ≥ 3 cytopenias were reported in 60% of patients ≥ 30 days post-infusion. Grade ≥ 3 cytokine release syndrome (CRS; per Lee et al. [Blood. 2014;124:188]) occurred in 15% of patients; 59% received tocilizumab for management of CRS. Grade ≥ 3 neurologic events (NEs) were reported in 31% of patients, and 38% received steroids for NE management. All CRS events and most NEs (37/43) resolved, as previously reported. There were no Grade 5 CRS events or NEs, and no new Grade 5 events occurred with additional follow-up. As previously reported, there were 2 cases of Grade 2 cytomegalovirus infection, 1 case each of Grade ≥ 3 hypogammaglobulinemia and Grade ≥ 3 tumor lysis syndrome, and no cases of Epstein-Barr virus-associated lymphoproliferation, replication-competent retrovirus, hemophagocytic lymphohistiocytosis, or KTE-X19-related secondary cancers. Median peak CAR T cell levels and median area under the curve (Days 0 - 28) were 98.9 cells/µL (range, 0.2 - 2565.8) and 1394.9 cells/µL (range, 3.8 - 27,700) in patients with ongoing responses at 12 months, 202.6 cells/µL (range, 1.6 - 2589.5) and 2312.3 cells/µL (range, 19.0 - 27,200) in patients who were relapsed at 12 months, and 0.4 cells/µL (range, 0.2 - 95.9) and 5.5 cells/µL (range, 1.8 - 1089.1) in nonresponders. Of the 57 efficacy-evaluable patients with data available, 84% had B cells detectable by flow cytometry at baseline. Of those in ongoing responses at 12 months, 10 of 26 patients (38%) with evaluable samples had B cells detectable at 3 months, and 10 of 18 (56%) had detectable B cells at 12 months; gene-marked CAR T cells were no longer detectable at 12 months in 5 of 28 evaluable patients (17%). Conclusions: The ZUMA-2 study continues to demonstrate substantial and durable clinical benefit of KTE-X19 therapy with manageable safety in patients with R/R MCL. Within this patient population, which lacks curative treatment options, most patients achieved durable CR, and no new safety signals were reported. Although early CAR T cell expansion was higher in patients who achieved an objective response, those who later relapsed showed elevated CAR T cell levels pointing to alternate mechanisms of secondary treatment failure in MCL.

Introduction: While most patients (pts) with cutaneous T-cell lymphoma (CTCL) have an indolent course, survival for stages ≥IIB is usually less than 5 years (Kim YH et al, Arch Dermatol 2003). When an aggressive approach of combination cytotoxic therapies and radiation in CTCL was compared to conservative sequential therapies in newly diagnosed pts, the increase in response rate with combination therapy was offset by toxicities, and no benefit in disease-free or overall survival was seen (Kaye FS et al, NEJM, 1989). Since then several novel agents have been approved in CTCL, including the CD30-directed antibody-drug conjugate brentuximab vedotin (BV) [in relapsed primary cutaneous ALCL and CD30-expressing mycosis fungoides (MF)], and HDAC inhibitors (HDACi). However, response rates of single agents are modest. Tolerable and more efficacious therapies are needed, including rational combinations of active biological agents. Evidence suggests that HDAC inhibition may upregulate CD30 expression (Hasanali ZS et al, Sci Transl Med 2015), supporting the combination of the HDACi romidepsin (R) with Brentuximab vedotin (BV) in pts with CTCL. Methods: In this multicenter phase I clinical trial, pts age ≥18 with stage ≥IB CTCL, good organ function, ECOG PS≤2, Results: At the time of abstract submission, 7 pts have been enrolled (DL0: n=3; DL1: n=3; expansion cohort: n=1). No pt experienced a cycle 1 DLT and DL1 was deemed the MTD. No pts were enrolled in the de-escalation cohorts. Enrollment in the expansion cohort is ongoing. Median age of pts was 64 years (range 51-79); 72% (n=5) were male; median ECOG PS 1 (0-2); median prior lines of systemic therapy were 4 (0-4), including 1 pt with prior HDACi, and 1 pt with prior BV and R exposure. All pts had MF. Stage at enrollment was stage IIB in 5 (72%), IB and IVA2 in 1 each (14% each). No pts have experienced G4 or 5 adverse events (AE). The only G3 AEs observed during treatment were transaminitis and fever (n=1 each), both resolved spontaneously. The most common AEs were nausea (71%), vomiting (43%), gastro-esophageal reflux, constipation, peripheral sensory neuropathy, anorexia, fatigue, and thrombophlebitis (29% each; see Table 1). Response assessment is available for 5 of 7 pts. The overall response rate was 80% (4/5), all of which partial responses, including 1 pt who had received both prior R and BV. The median change in mSWAT was a decrease of 59% from baseline (range -19.5 to -81.8%). After a median follow up of 6.1 months, median estimated progression-free survival was 12 months (PFS probability 0.42; 95%CI 0.1-1.0). Four pts came off treatment: 2 due to progression, 1 due to non-adherence related to COVID-19 concerns, 1 because of recurrent thrombophlebitis; 3 pts remain on treatment. Conclusion: Preliminary findings from this phase I study exploring the combination of R+BV indicate that R+BV is well tolerated at a dose of R 14mg/m2 and BV 1.2mg/kg given every 2 weeks and appears efficacious in CTCL. Updated results will be presented at the time of the meeting. Enrollment in the expansion cohort and correlative studies, including analysis of changes in CD30 expression after 1 dose of R, and association of response with CD30 expression, are ongoing.

Background: Patients with advanced-stage iNHL, including follicular lymphoma (FL) and marginal zone lymphoma (MZL), frequently relapse with standard treatment, underscoring a need for novel therapies. Axi-cel autologous anti-CD19 chimeric antigen receptor (CAR) T cell therapy is approved for the treatment of R/R large B cell lymphoma after ≥ 2 lines of systemic therapy. Here, we present the primary analysis of ZUMA-5, a Phase 2, multicenter, single-arm study of axi-cel in patients with R/R iNHL. Methods: Adults with FL (Grades 1-3a) or MZL (nodal or extranodal) had R/R disease after ≥ 2 lines of therapy (must include an anti-CD20 mAb plus an alkylating agent), and ECOG 0 - 1. Patients underwent leukapheresis followed by conditioning therapy (cyclophosphamide/fludarabine) and a single infusion of axi-cel at 2 × 106 CAR T cells/kg. The primary endpoint was objective response rate (ORR) by central review (per Lugano classification; Cheson, et al. J Clin Oncol. 2014). Secondary endpoints included complete response (CR) rate, duration of response (DOR), progression-free survival (PFS), overall survival (OS), incidence of adverse events (AEs), and levels of CAR T cells in blood and cytokines in serum. The primary efficacy analysis occurred when ≥ 80 treated patients with FL had ≥ 12-months follow-up. Results: As of 3/12/2020, 146 patients with iNHL (124 FL; 22 MZL) received axi-cel; 84 patients with FL had ≥ 12-months follow-up. The median age was 61 years (range, 34 - 79); 57% of patients were male. Thirty-eight percent of patients had ECOG 1, 86% had stage III/IV disease, 47% had ≥ 3 FLIPI, and 49% had high tumor bulk (GELF). Patients had a median 3 prior lines of therapy (range, 1 - 10); 64% had ≥ 3 prior lines. Progression < 2 years after initial chemoimmunotherapy (POD24) occurred in 55% of patients, and 68% were refractory to last prior treatment. Axi-cel was successfully manufactured for all enrolled patients. With a median follow-up of 17.5 months (range, 1.4 - 31.6), the ORR was 92% among efficacy-evaluable patients with iNHL (n = 104), with a 76% CR rate. In patients with FL (n = 84), the ORR was 94% (80% CR rate); in those with MZL (n = 20), the ORR was 85% (60% CR rate). ORR was comparable across key risk groups analyzed by FLIPI, POD24, GELF, refractory status, and prior lines of therapy. As of the data cutoff, 62% of all treated patients had ongoing responses (64% for FL). The medians for DOR, PFS, and OS were not reached; 12-month estimated rates were 72% (95% CI, 61 - 80), 74% (95% CI, 63 - 82), and 93% (95% CI, 86 - 97), respectively. AEs of any grade occurred in 99% of all treated patients. Grade ≥ 3 AEs occurred in 86% of patients with iNHL (85% in FL; 95% in MZL), most commonly neutropenia (33%), decreased neutrophil count (27%), and anemia (23%). Grade ≥ 3 cytokine release syndrome (CRS; per Lee, et al, Blood. 2014) occurred in 7% of patients with iNHL (6% in FL; 9% in MZL). Grade ≥ 3 neurologic events (NEs; per CTCAE v4.03) occurred in 19% of patients with iNHL (15% in FL; 41% in MZL). Most CRS (118/119) and NEs (81/87) of any grade resolved by data cutoff. Grade 5 AEs occurred in 3 patients: multisystem organ failure in the context of CRS (Day 7; related to axi-cel; n = 1 FL), aortic dissection (Day 399; unrelated to axi-cel; n = 1 FL), and coccidioidomycosis infection (Day 327; unrelated to axi-cel; n = 1 MZL). The median peak CAR T cell level was 38 cells/µL (range, 0 - 1415) in all treated patients with iNHL, with 36 cells/µL (range, 0 - 1415) in those with FL and 53 cells/µL (range, 2 - 453) in those with MZL. The AUC0 - 28 was 448 cells/µL × days (range, 6 - 19,900) in all treated patients with iNHL, with 422 cells/µL × days (range, 6 - 19,900) and 552 cells/µL × days (range, 13 - 6468) in those with FL and MZL, respectively. The median time to peak was 9 days (range, 8 - 371) in all patients, 8 days (range, 8 - 371) in patients with FL, and 15 days (range, 8 - 29) in patients with MZL. In efficacy-evaluable patients with FL, median peak CAR T cell levels were numerically greater in those with ongoing response at 12 months than in those who relapsed (P = .057). In all treated patients with FL, CAR T cell peak was associated with Grade ≥ 3 CRS (P = .031) and NEs (P = .005). Conclusions: Axi-cel had considerable and durable clinical benefit in patients with iNHL, with high ORR and CR rates. Axi-cel had a manageable safety profile, with lower rates of Grade ≥ 3 NEs observed in patients with FL vs those in patients with MZL and those previously reported in aggressive NHL (Locke, et al. Lancet Oncol. 2019).

Benozophenone (BP) type UV filters are extensively used in the personal care products to provide protection against the harmful effects of UV radiation. BPs are one of the primary components in the UV filter family, in which benophenone-2 (BP2) is widely used as a UV filter reagent in the sunscreen. Humans used these personal care products directly on skin and the chemicals will be washed away to the water system. BP2 has been identified as one of the endocrine disruptor chemicals, which can inference the synthesis, metabolism, and action of endogenous hormones. Environmentally, it has been found to contaminate water worldwide. In this study, we aimed to unfold the possible developmental toxicology of this chemical. Zebrafish are used as the screening model to perform in situ hybridization staining to investigate the effects of BP2 on segmentation, brain regionalization, and facial formation at four developmental stages (10-12 somite, prim-5, 2 and 5 days post-fertilization). Results showed 40 μM (9.85 mg L-1) or above BP2 exposure in zebrafish embryos for 5 days resulted in lipid accumulation in the yolk sac and facial malformation via affecting the lipid processing and the expression of cranial neural crest cells respectively. To conclude, the study alarmed its potential developmental toxicities at high dosage exposure.
