Résumé : We consider sequences-indexed by time (discrete stages)-of families of multistage stochastic optimization problems. At each time, the optimization problems in a family are parameterized by some quantities (initial states, constraint levels.. .). In this framework, we introduce an adapted notion of time consistent optimal solutions, that is, solutions that remain optimal after truncation of the past and that are optimal for any values of the parameters. We link this time consistency notion with the concept of state variable in Markov Decision Processes for a class of multistage stochastic optimization problems incorporating state constraints at the final time, either formulated in expectation or in probability. For such problems, when the primitive noise random process is stagewise independent and takes a finite number of values, we show that time consistent solutions can be obtained by considering a finite dimensional state variable. We illustrate our results on a simple dam management problem.

Résumé : Human land use changes have altered soil erosion for millennia with extensive consequences on terrestrial and aquatic ecosystems as well as on biogeochemical cycles along the land-ocean continuum. Despite their great importance, past erosion trends have high uncertainties limiting quantitative estimates of long-term erosion dynamics. Here, we applied a new approach combining well-dated paleo-records of soil erosion from lake sediments and a spatially distributed semi-empirical model to simulate annual soil erosion in six lake watershed systems in the Northwestern Alps during the Holocene. Progressive and abrupt changes in soil erosion are detected in the six watersheds. Progressive erosion explains most of the soil exports observed during the Early to Mid-Holocene period (from 11,700 to 3000 cal. yr. BP), while transient erosion crises (i.e., periods of abrupt increase in the erosion rates spanning approximately 1000 ± 500 years) led to massive soil losses during the Late-Holocene period (from 3000 to 1000 cal. yr. BP). Our coupled approach of proxy-model reconstruction shows that the transient erosion crises represent the half of the total soil erosion exports during the Holocene. These estimates defy current representations of large-scale soil erosion during the Holocene that do not consider transient erosion crises, hence potentially underestimating the anthropogenic perturbation of lateral fluxes and fate along the land-ocean continuum. Our results further suggest that erosion and/or land cover proxies need to be consistently integrated into model approaches when attempting to estimate past variations in mass exports from terrestrial to aquatic ecosystems over centennial to millennial timescales.

Résumé : Antibiotics (ABX) compromise the efficacy of programmed cell death protein 1 (PD-1) blockade in cancer patients, but the mechanisms underlying their immunosuppressive effects remain unknown. By inducing the down-regulation of mucosal addressin cell adhesion molecule 1 (MAdCAM-1) in the ileum, post-ABX gut recolonization by Enterocloster species drove the emigration of enterotropic α4β7 + CD4 + regulatory T 17 cells into the tumor. These deleterious ABX effects were mimicked by oral gavage of Enterocloster species, by genetic deficiency, or by antibody-mediated neutralization of MAdCAM-1 and its receptor, α4β7 integrin. By contrast, fecal microbiota transplantation or interleukin-17A neutralization prevented ABX-induced immunosuppression. In independent lung, kidney, and bladder cancer patient cohorts, low serum levels of soluble MAdCAM-1 had a negative prognostic impact. Thus, the MAdCAM-1–α4β7 axis constitutes an actionable gut immune checkpoint in cancer immunosurveillance.

Résumé : CD38-targeting immunotherapy is approved in combination with lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma (NDMM) that are transplant ineligible (TI) and is considered the best standard of care (SOC). To improve current SOC, we evaluated the added value of weekly bortezomib (V) to isatuximab plus lenalidomide and dexamethasone (IsaRd versus Isa-VRd). This Intergroupe Francophone of Myeloma phase 3 study randomized 270 patients with NDMM that were TI, aged 65–79 years, to IsaRd versus Isa-VRd arms. The primary endpoint was a minimal residual disease (MRD) negativity rate at 10 −5 by next-generation sequencing at 18 months from randomization. Key secondary endpoints included response rates, MRD assessment rates, survival and safety. The 18-month MRD negativity rates at 10 −5 were reported in 35 patients (26%, 95% confidence interval (CI) 19–34) in IsaRd versus 71 (53%, 95% CI 44–61) in Isa-VRd (odds ratio for MRD negativity 3.16, 95% CI 1.89–5.28, P < 0.0001). The MRD benefit was consistent across subgroups at 10 −5 and 10 −6 , and was already observed at month 12. The proportion of patients with complete response or better at 18 months was higher with Isa-VRd (58% versus 33%; P < 0.0001), as was the proportion of MRD negativity and complete response or better (37% versus 17%; P = 0.0003). At a median follow-up of 23.5 months, no difference was observed for survival times (immature data). The addition of weekly bortezomib did not significantly affect the relative dose intensity of IsaRd. Isa-VRd significantly increased MRD endpoints, including the 18-month negativity rate at 10 −5 , the primary endpoint, compared with IsaRd. This study proposes Isa-VRd as a new SOC for patients with NDMM that are TI. ClinicalTrials.gov identifier: NCT04751877

Résumé : Background: TRIPLET-HCC is a French, multicentre, randomized 1:1, open-label phase II-III trial designed to evaluate efficacy and safety of the triple combination (Arm-A) by the addition of ipilimumab (1 mg/kg for the first 4 cycles) to atezolizumab/bevacizumab (Q3W), versus the double atezolizumab/bevacizumab combination (Arm-B) for HCC eligible to systemic therapy in first line setting. The primary objective of phase II is the objective response rate in Arm-A, and overall survival in Arm-A versus Arm-B in phase III. In phase II, the first 15 pts randomized in Arm-A were assessed for a safety-run in aim to detect a potential signal of overtoxicity after the first four cycles of triple therapy (induction phase), thus allowing or forbidding the continuation of the trial. Methods: The trial started on March 2023 the 9 th . Adverse events (AE) and their imputability to treatment were reported in the eCRF by investigators. An independent data safety monitoring board (DSMB) was gathered 4 weeks after the last injection of ipilimumab of the 5 th and the 15 th patient randomized in Arm-A of phase II. The second DSMB meeting took place on November 2023 after extraction of data in November 2023 the 9 th . These data are presented in the present abstract. Results: At the DSMB meeting date, 15 patients in Arm-A were analyzed for safety while 13 patients had been randomized in Arm-B and had reached at least 4 cycles of treatment. In Arm-A, 12 pts completed the first 4 cycles of triple therapy, 1 pt received 3 cycles (sepsis), 1 pt only 2 (prednisone > 10 mg/day for grade-1 myocarditis which recovered), and 1 pt only 1 (sepsis and death). In Arm-B, 11 pts received the first 4 cycles of double therapy, 2 pts only 3 (anemia, lithiasic cholangitis). Three deaths occurred: 2 in Arm-A (1 possible related to immune-related (iR) hepatitis (not biopsy-proven) associated with sepsis, and 1 sudden death of unknow etiology), and one in Arm-B (tumor progression). Three pts in Arm-A (2 radiologic progressions, 1 death) and 1 pt in Arm-B (1 tumor progression with death) were withdrawn of the trial. Regarding grade-3/4 treatment-related adverse events (TRAE), 3 were reported in Arm-A (1 ASAT increase, 1 arterial hypertension, 1 colitis), and 2 in Arm-B (1 tumor bleeding, 1 arterial hypertension). Conclusions: The preliminary safety data from the TRIPLET-HCC trial suggest that the triple combination therapy is associated with a manageable safety profile, showing no unexpected signs of over toxicity. The DSMB's decision to continue the trial underscores the potential of this innovative therapeutic approach in improving outcomes for HCC patients. These findings support further investigation into the efficacy and long-term safety of the triple combination therapy in a broader patient population. Clinical trial information: NCT05665348 .

Résumé : Background: Follicular and marginal zone B cell lymphoma (FL; MZL) demonstrate an indolent course with heterogeneous outcomes anda potential for spontaneous remissions indicating immune system intervention. Therapeutic immunization is therefore an attractive approach but new antigens that evoke a strong immune response are needed. EO2463 expands pre-existing memory CD8+ T cells recognizing non-self protein sequences from gut bacteria which cross-react with B cell antigens and can kill HLA-A2 restricted cells (T2) loaded with target peptides. EO2463 includes 4 HLA-A2 synthetically produced epitopes which exhibit molecular mimicry with the B cell markers CD20, CD22, CD37, and CD268 (BAFF-receptor), as well as a the CD4 helper-epitope UCP2 derived from hTERT. EO2463 is being used to drive anti-tumor activity against B cell malignancies. Methods: Patients (pts) with FL and MZL, stage 1-3A, and HLA-A2, are eligible. In the safety lead-in pts with relapsed/refractory (R/R) disease were given EO2463 SC q2 weeks (w) x 4, then q4w, for a max of 12 months; at w7 lenalidomide (20 mg/day for 21/28 days up to 12 cycles) is added (EL), and if no complete remission (CR) at w19, rituximab (375 mg/m 2 IV, q1w x 4, then q4w x 4) is also added (ER 2 ). Doses evaluated: 150 μg and 300μg/peptide. Results: 3 pts received 150 μg/peptide and 6 pts 300 μg/peptide (EO2463 1 pat, EL 2 pts, ER 2 6 pts): 2 MZL, 7 FL pts with median 2 lines (range 1-4) of prior systemic therapy. No related grade ≥3 adverse events were seen with EO2463 monotherapy. Most common related events were grade 1 to 2 local administration site reactions in 5/9 pts. Adverse events during combination treatment were as expected for R 2 . PET-CT on w6 after EO2463 monotherapy suggested clinical activity in 4/9 pts (1 PR, 1 pt size reduction 15%, 1 pt 20% reduced tracer uptake, 1 pt 5/6 target lesions reduced metabolic activity). Overall objective responses (OR) were seen in 6/9 pts (67%; 1 st OR on EO2463 1 pat, EL 4 pts, ER 2 1 pat), with CR in 5/9 (56%) pts; median time to response was 18w (range 8-43w), response ongoing in 5 pts, range 24-76w. Expansion of specific CD8+ T cells against mimic peptides and targeted B cell antigens were detected in all responding pts, incl. 2 pts with no measurable B cells at baseline (prior anti-CD20). Expansion of specific T cells was detected at w5 in 5/6 pts and was maintained as long as currently tested (up to w94, 43w after last EO2463 dose). No decline in expansions were seen after start rituximab. Conclusions: EO2463 (300 μg/peptide) monotherapy, EL, and ER 2 are well tolerated, with encouraging clinical activity with EO2463 monotherapy and with subsequent CR in 5/9 pts on combo. Rapid and durable expansion of specific CD8+ T cells was seen in all responding pts, consistent with the preclinical hypothesis. Additional cohorts investigate EO2463 alone or in combination in newly diagnosed or R/R pts. Results will be reported at the meeting. Clinical trial information: NCT04669171 .
