#2244 Safety and efficacy of daratumumab monotherapy in lupus nephritis refractory to conventional and rescue therapies

Abstract Background and Aims Refractory lupus nephritis (LN) is defined as either no response to standard of care (SOC), i.e., failure to improve within 3–4 months or not achieving partial response within 12 months or complete response after 2 years of treatment. This condition is characterized by poor outcome, is often life-threatening, and represents a relatively unexplored clinical setting. A dysregulation of CD38 expression has been reported in Systemic lupus Erythematosus, and highly expressing CD38 plasma cells relegated in bone marrow niches inaccessible to conventional and biological agents could represent a source of repowering of the immune dysregulation. The efficacy and safety of daratumumab, a monoclonal antibody specifically directed at CD38, given without any other immunosuppressant or agents targeting B-cell-activating factor, were assessed in a discrete cohort of patients with refractory LN, in whom both SOC and rescue treatments had failed. Method Six patients (1 male and 5 females) aged 41.3 years (range 20 to 61 years) were treated with Daratumumab monotherapy. The treatment protocol consisted of 16 mg/kg daratumumab administered intravenously weekly for 8 weeks, then every two weeks 8 more times, and lastly monthly for 8 times. All patients had failed previous treatments with both SOC including either mycophenolate mofetil or cyclophosphamide-azathioprine, and rescue therapies including Rituximab, Ocrelizumab, Belimumab, and iv IgG. Results One out of six patients did not show clinical response after 6 months of therapy, and Daratumumab was discontinued. Five patients continued to be treated (total treatment maximum 22 infusions) and reached a 12-month observation. Renal biopsy performed before daratumumab administration revealed a class IV LN in 1 patient, class V LN in 1 patient, class III+V LN in 1 patient and class IV+V LN in the other 2. Three patients achieved a complete renal response and the other two a partial renal response. A significant decrease in proteinuria from 5.6 g per 24 h to 0.59 g per 24 h, 0.9 g per 24 h and 0.8 g per 24 h (P = 0.0010) at 3 months, 6 months and 12 months, respectively, was observed. The mean value of serum Creatinine (sCr) decreased from 2.3 to 1.5 mg/dl. The mean value of sCr decreased from 2.3 mg dl−1 to 1.5 mg/dl (P = 0.98) at 12 months. C3 and C4 levels increased from 72.8 (range, 0–99) to 101.6 (range, 78.0–135) mg/dl (P = 0.16) and from 9.4 (range, 5–14) to 20.4 (range, 13–30) mg/dl (P = 0.0182), respectively. A decrease in IgG mean levels from 971.7 mg dl−1 (range, 251–1546) to 512.3 mg/dl (range, 88–957), 481.7 (range, 84–878) mg/dl and 508.4 mg/dl (range, 192–685) at 3 months, 6 months and 12 months, respectively, was observed. Improvement of clinical symptoms was paralleled by seroconversion of anti-double-stranded DNA antibodies (p = 0.03), significant decrease in interferon-gamma values (p = 0.0006), BMCA-B-cell maturation antigen (p = 0.0005) and soluble CD163 levels (p = 0.045), and IL 10 levels (p = 0.0006). Clinical remission was substantiated by improvement of SLEDAI-2K score (p = 0.03). Daratumumab was generally well tolerated. Conclusion These data suggest that Daratumumab administered alone (i.e., without any other immunosuppressant or agents targeting B-cell activating factor) is highly effective in refractory LN. The multifaced effects of Daratumumab on the inflammatory burden and the interferon gamma profile could provide a restoration of the immune balance.

True-Positive 18F-Flotufolastat Lesions in Patients with Prostate Cancer Recurrence with Baseline-Negative Conventional Imaging: Results from the Prospective, Phase 3, Multicenter SPOTLIGHT Study.

18F-rhPSMA-7.3 (18F-flotufolastat) is a high-affinity prostate-specific membrane antigen-targeted diagnostic radiopharmaceutical for PET imaging in patients with prostate cancer. Here, we report findings from the SPOTLIGHT study (NCT04186845), assessing the performance of 18F-flotufolastat PET/CT for identifying prostate-specific membrane antigen-positive lesions confirmed by standard of truth (SoT) in men with biochemical recurrence of prostate cancer and negative conventional imaging at baseline. Methods: Men with biochemical recurrence received 296 MBq of 18F-flotufolastat intravenously and then underwent PET/CT 50-70 min later. 18F-flotufolastat PET/CT findings were evaluated by 3 masked central readers and verified using histopathology or follow-up confirmatory imaging (CT, MRI, bone scan, or 18F-fluciclovine PET/CT) as the SoT. The present analysis evaluated all patients who had negative conventional imaging at baseline, underwent 18F-flotufolastat PET/CT, and had SoT verification by histopathology or follow-up confirmatory imaging to report detection rate (DR), which is the number of patients with at least 1 PET-positive lesion, divided by the number of evaluable patients, and verified DR (VDR), which is the proportion of patients with at least 1 true-positive lesion as verified by SoT, of all patients scanned (PET-positive and PET-negative scans). DR and VDR were calculated and stratified according to prior therapy. Majority read data (agreement between ≥2 readers) are reported. Results: In total, 171 patients with negative baseline conventional imaging and SoT by histopathology or post-PET confirmatory imaging were evaluated. By majority read, the overall 18F-flotufolastat DR among these patients was 95% (163/171; 95% CI, 91.0%-98.0%), and 110 of 171 of these patients had at least 1 true-positive lesion identified (VDR, 64%; 95% CI, 56.7%-71.5%). In the postprostatectomy group (133/171), 8.3% of patients had at least 1 true-positive lesion in the prostate bed, 28% in pelvic lymph nodes, and 35% in other sites. Among those who had received radiotherapy (36/171), 50% of patients had true-positive detections in the prostate, 8.3% in pelvic lymph nodes, and 36% in other sites. Conclusion: 18F-flotufolastat frequently identified true-positive prostate cancer lesions in patients with negative conventional imaging. 18F-flotufolastat may help to better define sites of disease recurrence and inform salvage therapy decisions than does conventional imaging, potentially leading to improved outcomes.

Relapsed/Refractory Diffuse Large B-Cell Lymphoma: Is There Still a Role for Autologous Stem Cell Transplantation in the CAR T-Cell Era?

Recently, CD19-directed chimeric antigen receptor (CAR) T-cell therapies have revolutionized treatment strategies for diffuse large B-cell lymphoma (DLBCL). CAR T-cell therapy is increasingly used as a second-line therapy for patients with DLBCL with early relapse or refractoriness to initial chemoimmunotherapy and displaced high-dose chemotherapy, followed by autologous stem cell transplantation (ASCT) as the standard of care for these patients. However, patients with late relapse or chemosensitive disease still benefit from autologous stem cell transplantation. We will review practice-changing studies in early relapse (ZUMA-7 and TRANSFORM) under consideration of the negative BELINDA trial, with a focus on register data, comparing CAR T-cell therapy and ASCT for patients responding to salvage therapy.

Recombinant ADAMTS13: an effective rescue therapy for acute cTTP during pregnancy

Recombinant ADAMTS13: an effective rescue therapy for acute cTTP during pregnancy

A hybrid protocol CLAG-M, a possible player for the first-line therapy of patients with mixed phenotype acute leukemia. A Polish Adult Leukemia Group experience.

Mixed-phenotype acute leukemia (MPAL) is a rare disease with poor prognosis. So far, no standard approach has been established as the "know-how" of MPAL is based only on retrospective analyses performed on small groups of patients. In this study, a retrospective analysis of the outcomes of adult MPAL patients included in the PALG registry between 2005 and 2024 who received the CLAG-M hybrid protocol as induction or salvage therapy was performed. Sixteen of 98 MPAL patients received CLAG-M: eight as first-line and eight as salvage therapy. In the first line, two patients achieved partial response (PR), and six achieved complete remission (CR), of whom four successfully underwent allogeneic hematopoietic stem cell transplantation (alloHSCT). Two patients who did not undergo alloHSCT promptly relapsed. Within the whole group, the overall response rate (ORR) was 75% (n = 12/16). With the median follow-up of 13 months, six out of eight patients remain in CR, however, two of them died due to acute graft versus host disease. Out of eight patients who received CLAG-M in the second line, four patients (50%) obtained CR. AlloHSCT was conducted in seven cases, six of which were in CR. Only two patients remained in CR at the time of the last follow-up. Tolerance to treatment was good. The median times for severe neutropenia and thrombocytopenia were 22 days (range, 16-24) and 17 days (range, 12-24), respectively. Overall, grade 3-4 infections were observed in 12 cases, and all infections presented successful outcomes. CLAG-M is an effective first-line salvage regimen for MPAL with an acceptable safety profile. Early achievement of CR with prompt alloHSCT allows for satisfactory disease control.

Phage Therapy for Respiratory Infections: Opportunities and Challenges.

We are entering the post-antibiotic era. Antimicrobial resistance (AMR) is a critical problem in chronic lung infections resulting in progressive respiratory failure and increased mortality. In the absence of emerging novel antibiotics to counter AMR infections, bacteriophages (phages), viruses that infect bacteria, have become a promising option for chronic respiratory infections. However, while personalized phage therapy is associated with improved outcomes in individual cases, clinical trials demonstrating treatment efficacy are lacking, limiting the therapeutic potential of this approach for respiratory infections. In this review, we address the current state of phage therapy for managing chronic respiratory diseases. We then discuss how phage therapy may address major microbiologic obstacles which hinder disease resolution of chronic lung infections with current antibiotic-based treatment practices. Finally, we highlight the challenges that must be addressed for successful phage therapy clinical trials. Through this discussion, we hope to expand on the potential of phages as an adjuvant therapy in chronic lung infections, as well as the microbiologic challenges that need to be addressed for phage therapy to expand beyond personalized salvage therapy.

Stereotactic Body Radiotherapy in Recurrent and Oligometastatic Head and Neck Tumours.

The treatment of head and neck cancers (HNCs) encompasses a complex paradigm involving a combination of surgery, radiotherapy, and systemic treatment. Locoregional recurrence is a common cause of treatment failure, and few patients are suitable for salvage surgery. Reirradiation with conventional radiation techniques is challenging due to normal tissue tolerance limits and the risk of significant toxicities. Stereotactic body radiotherapy (SBRT) has emerged as a highly conformal modality that offers the potential for cure while limiting the dose to surrounding tissue. There is also growing research that shows that those with oligometastatic disease can benefit from curative intent local ablative therapies such as SBRT. This review will look at published evidence regarding the use of SBRT in locoregional recurrent and oligometastatic HNCs.

High-dose chemotherapy and peripheral blood stem cell transplantation as salvage therapy in primary mediastinal nonseminomatous germ cell tumors: The Indiana University experience.

Patients with relapsed primary mediastinal nonseminomatous germ cell tumor have low cure rates with salvage chemotherapy or surgery. The authors report survival outcomes of patients who received high-dose chemotherapy (HDCT) and peripheral blood stem cell transplantation (PBSCT) at Indiana University. The prospectively maintained Indiana University germ cell tumor database identified 32 patients with primary mediastinal nonseminomatous germ cell tumor who progressed after first-line cisplatin-based combination chemotherapy and received HDCT and PBSCT between 2006 and 2021. Therapy included two consecutive courses of HDCT consisting of 700 mg/m2 carboplatin and 750 mg/m2 etoposide, each for 3 consecutive days, and each followed by PBSCT. A second course was not given if the patient experienced progressive disease or prohibitive toxicity. Progression-free survival and overall survival were analyzed using the Kaplan-Meier method. Medians with 95% confidence intervals were also calculated along with 2-year probabilities. The median age at HDCT was 30 years (range, 18-61 years). With a median follow-up of 4.7 years (range, 1-14 years), the 2-year progression-free survival rate was 31% (95% confidence interval, 16%-47%), and the 2-year overall survival rate was 35% (95% confidence interval, 19%-52%). At last follow-up, nine patients (28%) remained without evidence of disease, including two platinum-refractory patients and two patients who were receiving HDCT as third-line therapy. There were three treatment-related deaths. Salvage HDCT and PBSCT is an active combination in patients who have relapsed primary mediastinal nonseminomatous germ cell tumor with curative potential and prolonged survival, including in platinum-refractory and third-line settings. The authors recommend this approach for initial salvage chemotherapy in this patient population.

The analysis of current international recommendations for the treatment of patients with stage III non-small cell lung cancer

The development of systemic antitumor treatment, targeted therapy and immune checkpoint inhibitor therapy (ICI) has changed the treatment outcome and prognosis for locally advanced non-small cell lung cancer (NSCLC). Modern recommendations provide for the division of such patients into potentially resectable and unresectable, and such division does not always correspond to stage IIIa, IIIb or IIIc of the disease. The treatment of resectable tumors is recommended to start with neoadjuvant chemoimmunotherapy (CIT), followed by surgical intervention aimed at radical tumor removal only in patients who respond to treatment. For unresectable tumors, the best approach is considered to be simultaneous chemoradiation therapy (CRT) followed by adjuvant ICI therapy, and the role of surgical interventions is limited to salvage surgery – residual tumor or local relapse removal after non-surgical self-treatment.This approach to the treatment of patients with stage III NSCLC is unlikely to fully satisfy specialists and patients – there is no complete consensus on the definition of the term «resectability»; the possibility of converting an unresect able tumor into a resectable one as a result of neoadjuvant treatment is denied, which is contrary to clinical practice. The objective of the article was the critical analysis of existing recommendations on the role of the surgical approach as a stage of complex treatment of stage III NSCLC from the surgeon’s point of view.

Rescue Therapy for Failed Mechanical Thrombectomy in Acute Ischemic Stroke: A Pooled Analysis of the Society of Vascular and Interventional Neurology Registry.

We aimed to evaluate the association between rescue therapy (RT) and functional outcomes compared to medical management (MM) in patients presenting after failed mechanical thrombectomy (MT). This cross-sectional study utilized prospectively collected and maintained data from the Society of Vascular and Interventional Neurology Registry, spanning from 2011 to 2021. The cohort comprised patients with large vessel occlusions (LVOs) with failed MT. The primary outcome was the shift in the degree of disability, as gauged by the modified Rankin Scale (mRS) at 90 days. Additional outcomes included functional independence (90-day mRS score of 0-2), symptomatic intracranial hemorrhage (sICH), and 90-day mortality. Of a total of 7,018 patients, 958 presented failed MT and were included in the analysis. The RT group comprised 407 (42.4%) patients, and the MM group consisted of 551 (57.5%) patients. After adjusting for confounders, the RT group showed a favorable shift in the overall 90-day mRS distribution (adjusted common odds ratio = 1.79, 95% confidence interval [CI] = 1.32-2.45, p < 0.001) and higher rates of functional independence (RT: 28.8% vs MM: 15.7%, adjusted odds ratio [aOR] = 1.93, 95% CI = 1.21-3.07, p = 0.005) compared to the MM group. RT also showed lower rates of sICH (RT: 3.8% vs MM: 9.1%, aOR = 0.52, 95% CI = 0.28-0.97, p = 0.039) and 90-day mortality (RT: 33.4% vs MM: 45.5%, aOR = 0.61, 95% CI = 0.42-0.89, p = 0.009). Our findings advocate for the utilization of RT as a potential treatment strategy for cases of LVO resistant to first-line MT techniques. Prospective studies are warranted to validate these observations and optimize the endovascular approach for failed MT patients. ANN NEUROL 2024.

Erector spinae plane block as a rescue therapy in following cholecystectomy: a historical cohort study.

The aim of this study is to evaluate the effect of erector spinae plane block (ESPB) as a rescue therapy in the recovery room. This single-center historical cohort study included patients who received either ESPB or intravenous meperidine for pain management in the recovery room. Patients' numeric rating scale (NRS) scores and opoid consumptions were evaluated. One hundred and eight patients were included in the statistical analysis. Sixty-two (57%) patients received ESPB postoperatively (pESPB) and 46 (43%) patients were managed with IV meperidine boluses only (IV). The cumulative meperidine doses administered were 0 (0-40) and 30 (10-80) mg for the pESPB and IV groups, respectively (p < 0.001). NRS scores of group pESPB were significantly lower than those of Group IV on T30 and T60. ESPB reduces the frequency of opioid administration and the amount of opioids administered in the early post-operative period. When post-operative rescue therapy is required, it should be considered before opioids.

What to do when traditional rescue therapies fail in acute severe ulcerative colitis.

Acute severe ulcerative colitis (ASUC) is a medical emergency that affects approximately 25% of patients with ulcerative colitis at some point in time in their lives. Outcomes of ASUC are highly variable. Approximately 30% of patients do not respond to corticosteroids and up to 50% of patients do not respond to rescue therapy (infliximab or cyclosporin) and require emergency colectomy. Data are emerging on infliximab dosing strategies, use of cyclosporin as a bridge to slower acting biologic agents and Janus kinase inhibition as primary and sequential therapy. In this review, we outline contemporary approaches to clinical management of ASUC in the setting of failure to respond to traditional rescue therapies.

Neoadjuvant Chemotherapy Improves Feasibility of Larynx Preservation and Prognosis in Resectable Locally Advanced Cervical Esophageal Cancer.

The optimal strategy for cervical advanced esophageal cancer remains controversial in terms of oncologic outcome as well as vocal and swallowing function. Recently, in East Asian countries, neoadjuvant chemotherapy (NAC) has been a standard strategy for advanced esophageal cancer. This study included 37 patients who underwent NAC, and 33 patients who underwent definitive chemoradiation therapy (dCRT) as larynx-preserving treatment for locally advanced cervical esophageal cancer from 2016 to 2021. This study retrospectively investigated outcomes, with comparison between NAC and dCRT for locally advanced cervical esophageal cancer. Larynx preservation was successful for all the patients with NAC and dCRT. After NAC, the rate of complete or partial response was 78.4%, and 30 patients underwent larynx-preserving surgery. On the other hand, after dCRT, the complete response rate was 71.9%, and 4 patients underwent larynx-preserving salvage surgery. Overall survival (OS) and progression free survival were similar between the two groups. However, for the patients with resectable cervical esophageal cancer (cT1/2/3), the 2-year OS rate was significantly higher with NAC (79.9%) than with dCRT (56.8%) (P = 0.022), and the multivariate analyses identified only NAC and cN0, one of the two as a significantly independent factor associated with a better OS (NAC: P = 0.041; cN0, 1: P = 0.036). The study showed that NAC as larynx-preserving surgery for resectable cervical esophageal cancer preserved function and had a better prognosis than dCRT. The authors suggest that NAC may be standard strategy for larynx preservation in patients with resectable cervical esophageal cancer.

Andexanet for Factor Xa Inhibitor–Associated Acute Intracerebral Hemorrhage

BackgroundPatients with acute intracerebral hemorrhage who are receiving factor Xa inhibitors have a risk of hematoma expansion. The effect of andexanet alfa, an agent that reverses the effects of factor Xa inhibitors, on hematoma volume expansion has not been well studied.MethodsWe randomly assigned, in a 1:1 ratio, patients who had taken factor Xa inhibitors within 15 hours before having an acute intracerebral hemorrhage to receive andexanet or usual care. The primary end point was hemostatic efficacy, defined by expansion of the hematoma volume by 35% or less at 12 hours after baseline, an increase in the score on the National Institutes of Health Stroke Scale of less than 7 points (scores range from 0 to 42, with higher scores indicating worse neurologic deficit) at 12 hours, and no receipt of rescue therapy between 3 hours and 12 hours. Safety end points were thrombotic events and death.ResultsA total of 263 patients were assigned to receive andexanet, and 267 to receive usual care. Efficacy was assessed in an interim analysis that included 452 patients, and safety was analyzed in all 530 enrolled patients. Atrial fibrillation was the most common indication for factor Xa inhibitors. Of the patients receiving usual care, 85.5% received prothrombin complex concentrate. Hemostatic efficacy was achieved in 150 of 224 patients (67.0%) receiving andexanet and in 121 of 228 (53.1%) receiving usual care (adjusted difference, 13.4 percentage points; 95% confidence interval [CI], 4.6 to 22.2; P=0.003). The median reduction from baseline to the 1-to-2-hour nadir in anti–factor Xa activity was 94.5% with andexanet and 26.9% with usual care (P<0.001). Thrombotic events occurred in 27 of 263 patients (10.3%) receiving andexanet and in 15 of 267 (5.6%) receiving usual care (difference, 4.6 percentage points; 95% CI, 0.1 to 9.2; P=0.048); ischemic stroke occurred in 17 patients (6.5%) and 4 patients (1.5%), respectively. There were no appreciable differences between the groups in the score on the modified Rankin scale or in death within 30 days.ConclusionsAmong patients with intracerebral hemorrhage who were receiving factor Xa inhibitors, andexanet resulted in better control of hematoma expansion than usual care but was associated with thrombotic events, including ischemic stroke.

Severe Disease Activity May Predispose Patients to Post-colectomy Duodenitis Associated with Ulcerative Colitis.

Objective Diffuse mucosal inflammation in the duodenum, distinct from peptic ulcer disease, has been repeatedly reported in patients with ulcerative colitis (UC). The pathogenesis of this complication remains uncertain; however, colectomy for medically refractory UC appears to trigger duodenitis. Cases in which colectomy was performed for UC were analyzed to characterize UC-related duodenitis after colectomy. Methods A retrospective case-control study of UC-related duodenitis that developed after colectomy in medically refractory UC between January 2011 and June 2020 was conducted. UC-related duodenitis was diagnosed based on typical clinical, endoscopic, and histological findings, and no duodenitis was endoscopically defined by the normal duodenal mucosa. Clinical and laboratory data, disease severity, and medications used were collected and compared between the UC-related and non-duodenitis cases. Results Ten UC-related duodenitis and 35 non-duodenitis cases were identified among 45 patients with UC who underwent esophagogastroduodenoscopy after colectomy. Disease severity, defined by the C-reactive protein level and partial Mayo score prior to colectomy, was significantly higher in duodenitis patients than in non-duodenitis patients. In comparison to non-duodenitis patients, duodenitis patients more frequently received rescue therapies with calcineurin inhibitors or anti-TNF-α agents at the time of colectomy (100% vs. 65.7%). Conclusion Patients with UC with higher disease activity, especially those who require rescue therapies with calcineurin inhibitors and anti-TNF-α agents, may be prone to developing UC-related duodenitis after colectomy.

Chimeric antigen receptor T-cell infusion for large B-cell lymphoma in complete remission: a center for international blood and marrow transplant research analysis.

CD19 CAR T-cell (CAR-T) therapy is commonly administered to patients with relapsed or refractory large B-cell lymphomas (LBCL), but salvage or bridging therapy can sometimes lead to a complete response (CR) prior to infusion. Limited studies have assessed the outcomes of patients infused in CR. A total of 134 patients with LBCL in CR prior to CAR-T infusion were identified from the CIBMTR registry, with median prior lines of therapy of 3 (range 2-9). At two years post-infusion, the probability of progression-free survival was 43.5% (95% CI 34.4-52.8) and the probability of overall survival was 63.8% (95% CI 54.4-72.6). The cumulative incidence rates of non-relapse mortality and relapse/progression at two years were 9.2% (95% CI 4.5-15.4) and 47.3% (95% CI 38.2-56.6), respectively. The rate of grade 3 or higher cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were 2.2% and 8.2%, respectively. In summary, CAR-T in heavily pretreated patients with LBCL who are in CR following two or more lines of prior therapy demonstrate that a subset of patients may remain free of progression at two years. Additionally, the toxicity profile was impressive with very low rates of grade 3 CRS and ICANS.

(Babcock or Soave Baulieux) Procedure for Coloanal Anastomosis: 03 Cases

The Soave Baulieux procedure is a surgical technique for performing a coloanal anastomosis in cases of pathological colorectal conditions. A coloanal anastomosis is performed through a sleeve of rectal muscularis after a two-stage mucosectomy. In the first stage, the colonic tube is exteriorised through the anal canal, and a few days later a direct coloanal anastomosis is performed in the second stage. This is a salvage operation and its results are not well documented in the literature. This is a study of three (03) consecutive patients, hospitalised and operated on using the Babcock or Soave Baulieux technique at the Department of Visceral Surgery A of the Hassan II University Hospital in Fez, Morocco. The objectives of this study were to evaluate the indications, operative results, postoperative morbidity and mortality, and long-term functional results. Our study concerns three (03) patients with colorectal cancer. In 66.7% of cases, the decision to perform the Soave Baulieux technique was taken preoperatively to avoid other complications related to the low colorectal anastomosis. After the operation, 66.7% of patients had a simple post-operative course and only one patient (33.3%) was re-operated after a complication (necrosis of the anastomosis from the distal segment to the anus). Only one patient had a permanent stoma. Quality of life and functional results were satisfactory in 66.7% of our patients.

Interventional therapy combined with tyrosine kinase inhibitors with or without immune checkpoint inhibitors as initial treatment for hepatocellular carcinoma with portal vein tumor thrombosis: a systematic review and meta-analysis

BackgroundInterventional therapy, in conjunction with tyrosine kinase inhibitors (TKIs), has shown promising outcomes for treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT). With the advent of immunotherapy, the combined use of immune checkpoint inhibitors (ICIs) has attracted great attention due to their potential effectiveness in advanced HCC. This study aims to compare the efficacy and safety of a triple therapy regimen (Interventional therapy, TKIs and ICIs, IT-TKI-ICI) with a dual therapy regimen (Interventional therapy and TKIs, IT-TKI) in the treatment of HCC and PVTT (HCC-PVTT).MethodsA comprehensive search was carried out in PubMed, Web of Science, Embase, Scopus, and the Cochrane Library databases. Primary outcome measures were overall survival (OS) and progression-free survival (PFS), while secondary outcomes included tumor response rate, adverse event incidence as well as downstaging surgery rate. Statistical analysis was conducted using Revman 5.4 software.ResultsThe meta-analysis finally included 6 cohort studies. The triple therapy group demonstrated significantly prolonged OS and PFS compared to the dual therapy group. Meanwhile, the former exhibited significantly higher rates of objective response rate (ORR), disease control rate (DCR) and better downstaging effects with a higher salvage surgery rate without significantly increasing adverse events.ConclusionIn comparison to dual therapy, the triple therapy with interventional therapy, TKIs, and ICIs demonstrates superior efficacy and equivalent safety for HCC-PVTT.

A research center’s experience of T-cell–redirecting therapies in triple-class refractory multiple myeloma

AbstractThe efficacies of chimeric antigen receptor T cells (CAR-Ts) and bispecific monoclonal antibodies (BiAbs) for triple-class refractory (TCR) myeloma have not previously been compared, and clinical data on how to rescue patients after relapse from these immunotherapies are limited. A retrospective study of 73 TCR patients included in trials was conducted: 36 received CAR-Ts and 37 received BiAbs. CAR-Ts produced a higher overall response rate (ORR) than BiAbs (97.1% vs 56.8%, P = .002). After a median of follow-up of 18.7 months, no significant difference in progression-free survival (PFS) was observed between the CAR-T and BiAbs groups (16.6 vs 10.8 months; P = .090), whereas overall survival (OS) was significantly longer in the CAR-T than in the BiAbs group (49.2 vs 22.6 months; P = .021). BiAbs after CAR-Ts yielded a higher ORR and longer PFS2 than did nonredirecting T-cell therapies after CAR-Ts (ORR: 87.5% vs 50.0%; PFS2: 22.9 vs 12.4 months). By contrast, BiAbs after BiAbs resulted in an ORR of 33% and PFS2 of 8.4 months, which was similar to that produced by the nonredirecting T-cell therapies (ORR: 28.6%; PFS2: 8.1 months). Although this is a pooled analysis of different trials with different products and the patient profile is different for CAR-Ts and BiAbs, both were effective therapies for TCR myeloma. However, in our experience, although the PFS was similar with the 2 approaches, CAR-T therapy resulted in better OS, mainly because of the efficacy of BiAbs as rescue therapy. Our results highlight the importance of treatment sequence in real-word experience.
