ABSTRACT
Background: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a heterogeneous but treatable immune-mediated neuropathy. Ofatumumab (OFA) is a fully human anti-CD20 monoclonal antibody that has shown promising efficacy in central demyelinating diseases, such as multiple sclerosis (MS). However, there is a lack of studies on the usage of OFA in peripheral demyelinating diseases, particularly CIDP. A case of relapsed and refractory CIDP with an ineffective response to conventional immunotherapy and intolerance to rituximab (RTX) but a positive response to subcutaneous injections of OFA is presented. Case presentation: The patient, a 46-year-old man diagnosed with CIDP, received high-dose intravenous methylprednisolone, intravenous immunoglobulin (IVIG), and plasma exchange(PE) during the acute phase of the disease, and long-term oral administration of prednisone, azathioprine (AZA), and mycophenolate mofetil (MMF) during the remission phase. However, the patient suffered six relapses over a five-year period, and because of these, along with an ineffective response to conventional immunotherapy, and intolerance to RTX, subcutaneous injections of OFA were selected as a prophylactic treatment against relapses. After a total of six injections of OFA, CD19+B cells were substantially depleted. The patient has been followed for more than 23 months without relapse. Conclusions: This case demonstrates the effectiveness and good tolerability of OFA in the treatment of relapsed and refractory CIDP. Further studies are needed to investigate the efficacy and safety of OFA in patients with relapsed and refractory CIDP, especially in those who have shown an ineffective response to conventional immunotherapy and are intolerant to RTX.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death all over the world, and brings a heavy social economic burden especially in China. Several immuno-combination therapies have shown promising efficacy in the first-line treatment of unresectable HCC and are widely used in clinical practice. Nevertheless, which combination is the most affordable one is unknown. Our study assessed the cost-effectiveness of the immuno-combinations as first-line treatment for patients with unresectable HCC from the perspective of Chinese payers. METHODS: A Markov model was built according to five multicenter, phase III, open-label, randomized trials (Himalaya, IMbrave150, ORIENT-32, CARES-310, LEAP-002) to investigate the cost-effectiveness of tremelimumab plus durvalumab (STRIDE), atezolizumab plus bevacizumab (A + B), sintilimab plus bevacizumab biosimilar (IBI305) (S + B), camrelizumab plus rivoceranib (C + R), and pembrolizumab plus lenvatinib (P + L). Three disease states were included: progression free survival (PFS), progressive disease (PD) as well as death. Medical costs were searched from West China Hospital, published literatures or the Red Book. Cost-effectiveness ratios (CERs) and incremental cost-effectiveness ratios (ICERs) were evaluated to compare costs among different combinations. Sensitivity analyses were performed to assess the robust of the model. RESULTS: The total cost and quality-adjusted life years (QALYs) of C + R, S + B, P + L, A + B and STRIDE were $12,109.27 and 0.91, $26,961.60 and 1.12, $55,382.53 and 0.83, $70,985.06 and 0.90, $84,589.01 and 0.73, respectively, resulting in the most cost-effective strategy of C + R with CER of $13,306.89 per QALY followed by S + B with CER of $24,072.86 per QALY. Compared with C + R, the ICER of S + B strategy was $70,725.38 per QALY, which would become the most cost-effective when the willing-to-pay threshold exceeded $73,500/QALY. In the subgroup analysis, with the application of Asia results in Leap-002 trial, the model results were the same as global data. In the sensitivity analysis, with the variation of parameters, the results were robust. CONCLUSION: As one of the promising immuno-combination therapies in the first-line systemic treatment of HCC, camrelizumab plus rivoceranib demonstrated the potential to be the most cost-effective strategy, which warranted further studies to best inform the real-world clinical practices.

Many therapies are available for the treatment of relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) after ≥ 2 lines of therapy, albeit with scant evidence on the comparative effectiveness of these therapies. This study used inverse probability of treatment weighting to indirectly compare treatment outcomes of epcoritamab from the EPCORE NHL-1 trial with individual patient data from clinical practice cohorts treated with chemoimmunotherapy (CIT) and novel therapies (polatuzumab-based regimens, tafasitamab-based regimens, and chimeric antigen receptor T-cell [CAR T] therapies) for third-line or later R/R large B-cell lymphoma (LBCL) and DLBCL. In this analysis, epcoritamab demonstrated significantly better response rates and overall survival rates than CIT, polatuzumab-based regimens, and tafasitamab-based regimens. No statistically significant differences in response rates or survival were found for epcoritamab compared with CAR T in R/R LBCL.

This single-arm, multicenter, phase 2 trial (NCT04106180) investigated the triple combination of sintilimab (anti-PD1 antibody), stereotactic body radiotherapy (SBRT) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in metastatic non-small cell lung cancer (NSCLC). With a median follow-up of 32.1 months, 18 (36.7%, 90% CI 25.3%-49.5%) of the 49 evaluable patients had an objective response, meeting the primary endpoint. Secondary endpoints included out-of-field (abscopal) response rate (ASR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (TRAEs). The ASR was 30.6% (95% CI 18.3%-45.4%). The median PFS and OS were 5.9 (95% CI 2.5-9.3) and 18.4 (95% CI 9.7-27.1) months, respectively. Any grade and grade 3 TRAEs occurred in 44 (86.3%) and 6 (11.8%) patients, without grade 4-5 TRAEs. Moreover, in pre-specified biomarker analyses, SBRT-induced increase of follicular helper T cells (Tfh) in unirradiated tumor lesions and patient's blood, as well as of circulating IL-21 levels, was found associated with improved prognosis. Taken together, the triple combination therapy was well tolerated with promising efficacy and Tfh may play a critical role in SBRT-triggered anti-tumor immunity in metastatic NSCLC.

BACKGROUND: The combination of targeted therapy and immunotherapy has improved the clinical outcomes of unresectable hepatocellular Carcinoma (HCC). However, the overall prognosis remains suboptimal. This study aims to evaluate the efficacy and safety of a novel combination of radiofrequency ablation (RFA) with lenvatinib plus sintilimab in unresectable HCC. METHODS: In this retrospective study, patients diagnosed with unresectable HCC were included and divided into two cohorts: RFA combined with lenvatinib plus sintilimab (R-L-S group) and lenvatinib plus sintilimab (L-S group). The primary efficacy endpoints were objective response rate (ORR) and progression free survival (PFS). Adverse events were analyzed to assess the safety profiles. RESULTS: The median follow-up periods for the entire cohort were 14.0 months. The R-L-S group (n = 60) had a significantly higher ORR than those with L-S alone (n = 62) (40.0% vs. 20.9%; p = 0.022). Moreover, patients in the R-L-S group had improved median PFS (12 vs. 8 months; p = 0.013) and median overall survival (24 vs. 18 months; p = 0.037), as compared with lenvatinib and sintilimab alone. No significant difference in treatment related adverse event (TRAE) of any grade between the two groups. The most common TRAEs of grade ≥ 3 were fatigue 10.0% (6/60) and hand-foot skin reaction 10.0% (6/60) in the R-L-S group and hand-foot skin reaction 11.3% (7/62) in the L-S group. CONCLUSION: In unresectable HCC patients, the incorporation of RFA to lenvatinib plus sintilimab demonstrated improved efficacy without compromising safety compared with lenvatinib plus sintilimab alone.

PURPOSE: Standard-dose immune checkpoint inhibitors (SD-ICIs) are the standard of care as initial therapy in microsatellite instable-high (MSI-H) advanced/metastatic colorectal adenocarcinomas (mCRC), but there are preclinical data to suggest that low-dose ICIs (LD-ICI) might also have similar efficacy. MATERIALS AND METHODS: A retrospective study of patients with MSI-H mCRC receiving ICIs between June 2017 and January 2023 was conducted. The primary end point of the study was 12-month progression-free survival (PFS), which was computed using the Kaplan-Meier method. RESULTS: A total of 65 patients were available for analysis during the study period. Sixty patients (92%) received nivolumab, whereas the remaining received pembrolizumab. First-line ICIs were received by 18 patients (28%), whereas 47 patients (72%) received ICIs during later lines. Thirty patients (47%) received LD-ICIs (all received nivolumab), with the remaining receiving SD-ICIs (53%). At a median follow-up of 16.5 (95% CI, 11.8 to 21.2) months, median PFS was not reached in the entire cohort. The 12-month PFS rate in the LD-ICI cohort was 90%, whereas it was 75.8% in the SD-ICI cohort. There were no statistical differences in patients receiving ICIs as first-line therapy (12 months PFS-94.4%) or during later lines of therapy (12-month PFS-77.9%; P = .56). CONCLUSION: ICIs in the current study show survivals which are similar to those seen in seminal trials in patients with MSI-H mCRC. Low-dose ICIs appear to work in MSI-H mCRC and should be explored prospectively in clinical trials. Patients with MSI-H status should be exposed to ICIs, whether initially or later during treatment, whenever feasible.

PURPOSE: To evaluate the efficacy and safety of transarterial chemoembolization (TACE) combined with regorafenib (hereafter, TACE-regorafenib) or camrelizumab (hereafter, TACE-camrelizumab) for treating hepatocellular carcinoma (HCC) with untreatable progression after TACE and sorafenib therapy. METHODS: The medical records of patients with HCC who received TACE-regorafenib or TACE-camrelizumab between September 2018 and December 2023 were retrospectively evaluated. Therapeutic response, overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were compared between the two groups. RESULTS: A total of 76 patients were enrolled in this study, with 41 and 35 patients in the TACE-regorafenib and TACE-camrelizumab groups, respectively. The objective response rates in the TACE-regorafenib and TACE-camrelizumab groups were 9.8% and 8.6%, respectively, with no statistically significant difference between the two groups (P = 0.859). Similarly, there was no statistically significant difference in disease control rates between the two groups (61.0% vs 68.6%, P = 0.838). The median OS was 11 months in the TACE-regorafenib group and 10 months in the TACE-camrelizumab group, with no significant difference between the two groups (P = 0.348). The TACE-regorafenib group had a median PFS of 7 months, which was significantly longer than that of the TACE-camrelizumab group (4 months, P = 0.004). There was no significant difference in the incidence of AEs between the two groups (P = 0.544). CONCLUSIONS: TACE-regorafenib was safe, well-tolerated, and showed promising efficacy in patients with sorafenib-refractory advanced HCC, whereas TACE-camrelizumab demonstrated similar survival benefits.

This single-arm phase 2 trial (ChiCTR2100046715) examined previously untreated patients with advanced esophageal squamous cell carcinoma (ESCC) who received four cycles of paclitaxel with carboplatin every 3 weeks. Toripalimab was infused intravenously every 3 weeks for 12 months, or until disease progression or intolerable toxicity. Radiotherapy that encompassed the primary lesions and metastases commenced in the third cycle. The median progression-free survival time was 9.8 months (95% confidence interval [CI]: 6.8-not estimable) in the intent-to-treat population, failing to meet the pre-specified primary endpoints. Secondary endpoints included an objective response rate of 45.5%, a disease control rate of 57.6%, and a median duration of response of 11.5 months (interquartile range, 6.4-15.0). The 1-year progression-free survival and overall survival rates were 41.9% (95% CI: 27.7-63.5) and 69.7% (95% CI: 55.7-87.3), respectively. Lymphopenia was the most frequent grade ≥3 adverse event (82%), and an esophageal fistula developed in three patients (9.1%). No treatment-related deaths occurred. In prespecified exploratory biomarker analysis, higher densities of CD8 + T cells, CD11c+ dendritic cells, and CD68+ macrophages correlated with improved tumor response and prognosis. Radiotherapy supplementation to first-line chemo-immunotherapy for treatment-naive advanced ESCC demonstrated some antitumor activity and manageable safety profiles, warranting further randomized controlled trials.

BACKGROUND: To compare the difference of postoperative anastomotic leakage (AL) rate between neoadjuvant chemoradiotherapy (NCRT) with pembrolizumab and NCRT group, and investigate the risk factors of developing AL for locally advanced esophageal squamous cell cancer (ESCC). MATERIALS AND METHODS: The GF was contoured on the pretreatment planning computed tomography and dosimetric parameters were retrospectively calculated. Univariate and multivariate logistic regression analysis was performed to determine the independent risk predictors for the entire cohort. A nomogram risk prediction model for postoperative AL was established. RESULTS: A total of 160 ESCC patients were included for analysis. Of them, 112 were treated with NCRT with pembrolizumab and 44 patients with NCRT. Seventeen (10.6%) patients experienced postoperative AL with a rate of 10.7% (12/112) in NCRT with pembrolizumab and 11.4% (5/44) in NCRT group. For the entire cohort, mean, D50, Dmax, V5, V10 and V20 GF dose were statistically higher in those with AL (all p < 0.05). Multivariate logistic regression analysis indicated that tumor length (p = 0.012), volume of GF (p = 0.003) and mean dose of GF (p = 0.007) were independently predictors for postoperative AL. Using receiver operating characteristics analysis, the mean dose limit on the GF was defined as 14 Gy. CONCLUSION: Based on our prospective database, no significant difference of developing AL were observed between NCRT with pembrolizumab and NCRT group. We established an individualized nomograms based on mean GF dose combined with clinical indicators to predict AL in the early postoperative period.

BACKGROUND: TCbHP (taxane + carboplatin + trastuzumab + pertuzumab) is the preferred neoadjuvant therapy regimen for human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, no consensus exists regarding whether specific populations may be exempt from carboplatin, allowing for de-escalation to the THP (taxane + trastuzumab + pertuzumab) regimen. Additionally, the optimal number of cycles for neoadjuvant THP remains unclear. We compared the efficacy and safety of neoadjuvant TCbHP and THP regimens, providing clinicians with a nuanced perspective to guide their treatment regimen selection. METHODS: This multicenter real-world study included patients with HER2-positive breast cancer undergoing neoadjuvant TCbHP or THP between March 2019 and February 2023. Efficacy was assessed through the pathological complete response (pCR) rate, while safety was evaluated through monitoring adverse events. RESULTS: Among 220 patients, 103 received 6 cycles of TCbHP (TCbHP×6), 83 received 6 cycles of THP (THP×6), and 34 received 4 cycles of THP (THP×4). The TCbHP×6 cohort exhibited a 66% pCR rate compared with 53% in the THP×6 cohort (P = 0.072). Subgroup analysis revealed that in patients aged ≤ 50 years, those with hormone receptor (HR)-negative status, and those with clinical stage T2, the pCR rate of the TCbHP×6 regimen was significantly higher than the THP×6 regimen (P < 0.05). The TCbHP×6 cohort reported higher frequencies of any-grade adverse events (99% versus 86.7%) and grade 3-4 events (49.5% versus 12%) than the THP×6 cohort. Propensity score matching identified 27 patient pairs between the THP×6 and THP×4 cohorts, indicating a significantly higher pCR rate for the THP×6 regimen than the THP×4 regimen (63% versus 29.6%, P = 0.029). CONCLUSIONS: The TCbHP×6 regimen is favored for individuals aged ≤ 50 years and those aged > 50, ≤60 years with HR-negative status or clinical stage T2-4. For patients in compromised general condition or lacking the specified indications, the THP×6 regimen emerges as a lower-toxicity alternative with satisfactory efficacy. To ensure treatment efficacy, a minimum of 6 cycles of neoadjuvant THP is required.

Libtayo® (cemiplimab-rwlc) injection for intravenous use was recently approved by the US Food and Drug Administration (FDA) for locally advanced basal cell carcinoma (laBCC) and metastatic basal cell carcinoma (mBCC), both being the advanced stages of BCC. In the past, it was approved by the FDA for the treatment of metastatic cutaneous squamous cell carcinoma (mCSCC) and locally advanced cutaneous squamous cell carcinoma (laCSCC), both being the advanced stages of CSCC. Cemiplimab is a monoclonal antibody that works by blocking the programmed death-1 pathway. In two open-label, single-arm, phase 2 studies, cemiplimab was investigated for the treatment of advanced stages of BCC (study 1620, NCT03132636) and advanced stages of CSCC (study 1540, NCT02760498). The primary endpoint was objec-tive response rate (ORR) per independent central review. In the study 1620, both mBCC and laBCC received cemiplimab 350 mg every 3 weeks. ORR was 21% (6/28) and 31% (26/84) in the mBCC and laBCC groups, respectively. In the study 1520, mCSCC was divided into two groups: one receiving cemiplimab 350 mg every 3 weeks (Q3W) and another receiving 3-mg/kg cemiplimab every 2 weeks (Q2W); the third group, laCSCC, received cemiplimab 3 mg/kg every 2 weeks. ORR was 41% (23/56) in the Q3W group, 49% (29/59) in the Q2W group, and 44% (34/78) in the laCSCC group. An acceptable safety profile and antitumor activity was discovered in patients treated with cemiplimab. The recommended dosage for cemiplimab to treat advanced stages of BCC and CSCC is 350 mg every 3 weeks administered intravenously over 30 min.

BACKGROUND: Sjögren's disease is a chronic autoimmune disease with an unmet need for targeted therapies. The aim of the TWINSS study is to evaluate the safety and efficacy of iscalimab, a monoclonal antibody against CD40, in patients with active Sjögren's disease. METHODS: This randomised, double-blind, placebo-controlled, phase 2b study, conducted at 71 sites in 23 countries, enrolled patients aged 18 years or older fulfilling the American College of Rheumatology/European Alliance of Associations for Rheumatology (EULAR) 2016 criteria. In the dose-ranging cohort 1, patients with a EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score of 5 or higher and a EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) score of 5 or higher were randomly assigned (1:1:1:1) to subcutaneous iscalimab 150 mg, 300 mg, 600 mg, or placebo. In the proof-of-concept cohort 2, patients with an ESSDAI score of less than 5, ESSPRI (dryness or fatigue) score of 5 or higher, and Impact of Dry Eye on Everyday Life score of 30 or higher were randomly assigned (1:1) to iscalimab 600 mg or placebo. The sponsor, investigator, site personnel, and patients were masked to the treatment assignment. The primary objectives were to demonstrate a dose-response relationship of iscalimab based on the change in ESSDAI from baseline to week 24 in cohort 1 by Multiple Comparison Procedure-Modelling (MCP-Mod), and to assess the effect of iscalimab 600 mg on ESSPRI at week 24 in cohort 2. All the efficacy analyses included all patients who were randomly assigned, and safety analysis included all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov (NCT03905525), and is complete. FINDINGS: Between Oct 1, 2019, and Feb 28, 2022, 460 patients were screened; 173 patients were assigned to cohort 1 (44 to iscalimab 150 mg, 43 to 300 mg, 43 to 600 mg, and 43 to placebo) and 100 to cohort 2 (50 to each group). In cohort 1, the MCP step showed a significant dose-response relationship for placebo-adjusted ESSDAI change from baseline in one of four models (Linlog model, one-sided p=0·0041). ESSDAI decreased from baseline to week 24 with all three doses of iscalimab; 150 mg and 600 mg doses showed statistically significant improvement (placebo-adjusted least squares [LS] mean difference -3·0 [95% CI -4·9 to -1·1]; p=0·0025 for 150 mg and -2·9 [-4·9 to -1·0]; p=0·0037 for 600 mg). In cohort 2, ESSPRI showed a trend towards improvement with iscalimab 600 mg (placebo-adjusted LS mean change from baseline -0·57 points [95% CI -1·30 to 0·15]; p=0·12). Serious adverse events were reported in nine patients in cohort 1 (one [2%] of 43 in the placebo group, one [2%] of 44 in the iscalimab 150 mg group, three [7%] of 42 in the 300 mg group, four [9%] of 44 in the 600 mg group) and four patients in cohort 2 (two [4%] of 50 in each group). No deaths occurred over the 24-week period. INTERPRETATION: The study met the primary objective of demonstrating a significant dose-response relationship with iscalimab in terms of disease activity at week 24. Iscalimab was well tolerated and showed initial clinical benefit over placebo in two distinct populations of patients with Sjögren's disease, to be confirmed in larger trials.

Background: Intermediate-stage (BCLC-B) hepatocellular carcinoma (HCC) beyond the up-to-11 criteria represent a significant therapeutic challenge due to high and heterogeneous tumor burden. This study evaluated the effectiveness and safety of transarterial chemoembolization (TACE) in combination with lenvatinib and tislelizumab for these patients. Methods: In this retrospective cohort study, patients with unresectable intermediate-stage HCC beyond the up-to-11 criteria were enrolled and divided into TACE monotherapy (T), TACE combined with lenvatinib (TL), or TACE plus lenvatinib and tislelizumab (TLT) group based on the first-line treatment, respectively. The primary endpoint was overall survival (OS). The secondary outcomes included progression-free survival (PFS), tumor response according to RESIST1.1 and modified RECIST, and adverse events (AEs). Results: There were 38, 45, and 66 patients in the T, TL, and TLT groups, respectively. The TLT group exhibited significantly higher ORR and DCR than the other two groups, as assessed by either mRECIST or RECIST 1.1 (all P<0.05). Median PFS and OS were significantly longer in the TLT group compared with the T group (PFS: 8.5 vs. 4.4 months; OS: 31.5 vs. 18.5 months; all P<0.001) and TL group (PFS: 8.5 vs. 5.5 months; OS: 31.5 vs. 20.5 months; all P<0.05). The incidence of TRAEs was slightly higher in the TLT and TL groups than in the T group, while all the toxicities were tolerable. No treatment-related death occurred in all groups. Conclusions: TACE combined with lenvatinib and tislelizumab significantly improved the survival benefit compared with TACE monotherapy and TACE plus lenvatinib in patients with intermediate-stage HCC beyond the up-to-11 criteria, with an acceptable safety profile.

Sacituzumab Govitecan (SG) is an antibody-drug conjugate that has demonstrated efficacy in patients with TROP-2 expressing epithelial cancers. In a xenograft model of intracranial breast cancer, SG inhibited tumor growth and increased mouse survival. We conducted a prospective window-of-opportunity trial (NCT03995706) at the University of Texas Health Science Center at San Antonio to examine the intra-tumoral concentrations and intracranial activity of SG in patients undergoing craniotomy for breast cancer with brain metastases (BCBM) or recurrent glioblastoma (rGBM). We enrolled 25 patients aged ≥18 years diagnosed with BCBM and rGBM to receive a single intravenous dose of SG at 10 mg/kg given one day before resection and continued on days 1 and 8 of 21-day cycles following recovery. The PFS was 8 months and 2 months for BCBM and rGBM cohorts, respectively. The OS was 35.2 months and 9.5 months, respectively. Grade≥3 AE included neutropenia (28%), hypokalemia (8%), seizure (8%), thromboembolic event (8%), urinary tract infection (8%) and muscle weakness of the lower limb (8%). In post-surgical tissue, the median total SN-38 was 249.8 ng/g for BCBM and 104.5 ng/g for rGBM, thus fulfilling the primary endpoint. Biomarker analysis suggests delivery of payload by direct release at target site and that hypoxic changes do not drive indirect release. Secondary endpoint of OS was 35.2 months for the BCBM cohort and 9.5 months for rGBM. Non-planned exploratory endpoint of ORR was 38% for BCBM and 29%, respectively. Exploratory endpoint of Trop-2 expression was observed in 100% of BCBM and 78% of rGBM tumors. In conclusion, SG was found to be well tolerated with adequate penetration into intracranial tumors and promising preliminary activity within the CNS.

Bimekizumab is a novel humanized bispecific monoclonal immunoglobulin G1 (IgG1) antibody that dually inhibits both IL-17A and IL-17F. Investigation of the pivotal role of IL-17A, and more recently, IL-17F, in the pathogenesis of psoriasis has underscored the utility of biologics targeting these cytokines in the treatment of the disease. Treatments include the anti-IL-17 biologics specifically targeted against IL-17A (secukinumab and ixekizumab) or its receptor (brodalumab). Recent clinical trials proved the efficacy and safety of bimekizumab in the treatment of moderate-to-severe plaque psoriasis and even showed it to be superior to other psoriasis biologic treatments in regards to efficacy and rapidity of response. These are important factors to consider when discussing treatment options with patients as psoriasis patients commonly desire fast-acting results. In this case, we describe clearance of moderate-to-severe plaque psoriasis within 72 hours of treatment with bimekizumab, one of the fastest reported clearance times in the medical literature.

BACKGROUND AND OBJECTIVE: In Italy, the management of metastatic non-small cell lung cancer and melanoma leads to significant healthcare challenges, necessitating cost-effective treatment strategies and offering valuable insights for healthcare policymakers and stakeholders. This study was designed to assess the costs, quality-adjusted life-years (QALYs) and disability-adjusted life-years (DALYs) associated with the health and economic outcomes of (1) pembrolizumab-combined chemotherapy administered as a first-line treatment for metastatic non-squamous and squamous non-small cell lung cancer (NSCLC) where the tumour presents with a programmed death-ligand 1 expression level < 50% and of (2) adjuvant pembrolizumab treatment for stage III melanoma. METHODS: Three cost-effectiveness models developed by MSD were investigated for each treatment indication. A unique model was built to assess the overall effect of pembrolizumab versus chemotherapy or watchful waiting in patients with lung cancer or melanoma, respectively. Theoretical cohorts of patients with metastatic squamous and non-squamous NSCLC were followed over time using a partitioned survival model with weekly cycles. A weekly cycle Markov model was employed for melanoma. The analysis was conducted from the Italian National Health Service perspective, considering a time horizon of 40 years (lifetime). A single closed cohort of treatable patients was followed over time for each indication (4000, 7000 and 900 for NSCLC squamous, non-squamous and melanoma, respectively). The costs evaluated included those for adverse drug events, non-drug disease management, subsequent treatment and terminal care. Drug acquisition and administration costs were excluded. RESULTS: For each treatment indication assessed, pembrolizumab produced downstream direct cost offsets (- 122,498,568, - 133,369,076 and - 32,993,242 for NSCLC squamous, non-squamous and melanoma indications, respectively), increased quality of life (+2088, +5317 and +2307 QALYs for NSCLC squamous, non-squamous and melanoma indications, respectively) and reduced disability (- 2658, - 7202 and - 3029 DALYs for NSCLC squamous, non-squamous and melanoma indications, respectively). Across indications, the total cost offsets of pembrolizumab were - 288,860,885, with 9712 QALYs gained and 12,889 DALYs avoided. CONCLUSIONS: The analysis demonstrated that, compared with chemotherapy, pembrolizumab is more cost effective in Italy as a first-line treatment in patients with metastatic squamous or non-squamous NSCLC and, if compared with watchful waiting, as adjuvant treatment in patients with stage III melanoma. The present analysis suggested that pembrolizumab use could lead to important health benefits for patients while offsetting a portion of cancer care costs.

AIM: Evaluation in real clinical practice of the effectiveness and safety of levilimab therapy in patients with highly and moderately active rheumatoid arthritis (RA). MATERIALS AND METHODS: A prospective observational study (6 months) involving 35 patients with RA (29 women and 6 men, mean age 53.17±13.2 years) who were treated at the Ochapovsky Regional Clinic Hospital of Krasnodar Region. All patients included in the study were prescribed the drug levilimab (Ilsira). RESULTS: After 1 month of observation, there was a decrease in the clinical and laboratory activity of the process in the form of a decrease in the number of painful joints - 17.0 (14.0; 20.0) vs 8.0 (6.0; 10.0); p=0.000001, number of swollen joints - 3.0 (2.0; 4.0) vs 0.0 (0.0; 0.0); p=0.000002, reduction in pain intensity according to visual analog scale - 60.0 (60.0; 70.0) mm vs 30.0 (20.0; 40.0) mm (p=0.000001). Also, by the end of the first month of therapy, there was a decrease in clinical activity indices DAS28-ESR by 43%, SDAI by 60%, CDAI by 55%. Positive dynamics of laboratory parameters were noted - a decrease in erythrocyte sedimentation rate by 76%, a decrease in C-reactive protein level by 98%. By the 6th month of therapy, a decrease in RF by 36% and ACCP by 11% was recorded, but the dynamics of these indicators did not reach statistical significance. By the end of 4 weeks of treatment, 24 (68.6%) patients showed an increase in the level of total blood cholesterol - 5.1 (3.91; 6.0) mmol/L vs 6.1 (4.99; 7.07) mmol/L (p=0.000006), while 11 (45.8%) patients from this group had initially elevated cholesterol levels (6.4±0.6 mmol/L). In 5 (14.3%) patients, an increase in alanine aminotransferase (ALT) was recorded in the 4th week - 17.0 (11.0; 25.0) U/L vs 32.0 (22.0; 43.0) U/L (p=0.000062) and aspartate aminotransferase (AST) - 19.0 (14.0; 24.0) U/L vs 25.0 (18.0; 36.0) U/L (p=0.000171), in 1 (2.85%) of the patient, an increase in ALT and AST above normal was noted (ALT 144 U/L, AST 52 U/L), which required discontinuation of levilimab. In 2 (5.7%) patients, by the end of the 4th week a decrease in the absolute number of neutrophils was registered - 3.2 (2.6; 4.0)×10E9/L vs 2.3 (2.0; 2.5)×10E9/L (p=0.002), which did not require discontinuation of treatment, since the number of cells remained more than 1×10E9/L. During treatment with levilimab 162 mg subcutaneously once a week, the proportion of patients taking prednisolone decreased from 46% at the start of therapy to 11% at the end of 6 months of therapy. CONCLUSION: Levilimab is a highly effective drug for the treatment of patients with highly and moderately active RA and has a favorable tolerability and safety profile.

INTRODUCTION: Docetaxel plus ramucirumab (DTX + RAM) therapy is a standard treatment for previously treated lung cancer, but many adverse events have been reported. This retrospective study was conducted to examine if the side effects of DTX + RAM therapy can be minimized by the combined use of oral dexamethasone (DEX), and to assess the therapeutic effect of DTX + RAM in patients with recurrent lung cancer. METHODS: Forty patients with relapsed non-small cell lung cancer who underwent DTX + RAM therapy were divided into two groups based on the concomitant use of oral DEX, and the therapeutic effects and toxicities in the two groups were compared. RESULTS: The objective response rate (ORR) was significantly better in the DEX group (P = 0.0203). The median progression-free survival (PFS) was 5.20 months vs 2.87 months (P = 0.064) in the DEX and non-DEX groups, respectively. However, the median overall survival (OS) was significantly better in the DEX group (15.17 months vs 7.37 months, P = 0.0317). The frequency of fluid retention within six months of the start of treatment was 10.0% vs 42.5% in the DEX and non-DEX groups, respectively, with the fluid retention rate being significantly higher in the non-DEX group (P = 0.039).Conclusion: Concomitant use of oral DEX during DTX + RAM therapy may facilitate the long-term continuation of treatment and contribute to OS prolongation.
