PALETTE- Adaptive Platform Trial for Personnalisation of Sepsis Treatment in Children and Adults: a Multi-national, Treatable Traits-guided, Adaptive, Bayesian Basket Trial"

PALETTE is a perpetual adaptive platform to efficiently study sepsis interventions within 'treatable traits' in all-ages patients enabling prompt evaluation of pandemic treatments. Treatable traits, therapeutic targets identified by phenotypes or endotypes (defined by biological mechanism or by treatment response) through validated biomarkers (measurable characteristic reflecting normal or pathogenic processes, or treatment responses), may include multi-omics, cellular, immune, metabolic, endocrine features, or intelligent algorithms. PALETTE Bayesian adaptive design enables parallel investigations of multiple interventions for sepsis, and quick inclusion of pandemic pathogens. PALETTE's new conceptual model will respond to the challenges of standard approaches, i.e. series of sepsis trials, each investigating one or two interventions, expensive, time consuming, and inappropriate in pandemic context.

Familial Mediterranean Fever (FMF): Emerging Concepts in Diagnosis, Pain Management, and Novel Treatment Options: A Narrative Review

Review

Author: Robin, Connor J ; Ahmadzadeh, Shahab ; Norwood, Haley A ; Kaye, Alan D ; Parker-Actlis, Tomasina Q ; Barrie, Sonnah ; Baptiste, Carlo Jean ; Islam, Kazi N ; Islam, Rahib K ; Shekoohi, Sahar ; McGregor, David W ; Nguyen, Ivan D

PURPOSE OF REVIEWFamilial Mediterranean Fever (FMF) is a hereditary autoinflammatory disorder predominantly affecting individuals of Mediterranean and Middle Eastern descent, including those with certain heritages including Sephardic Jewish, Armenian, Turkish, and Arab. The disorder affects up to 1 in 200 people making it a very common etiology for pain states worldwide, including serositis mediated painful states of the chest, joint, and abdomen.RECENT FINDINGSDefined by recurrent episodes of fever and inflammation, FMF can lead to not only severe pain, but complications such as renal amyloidosis, if untreated. This narrative review explores the genetic basis, clinical manifestations, diagnostic criteria, and current management strategies for FMF. Mutations in the MEFV gene result in the dysregulation of the pyrin inflammasome, leading to excessive production of inflammatory cytokines. Diagnosis primarily relies on clinical criteria supported by genetic testing. Colchicine remains the cornerstone of treatment, effectively preventing inflammatory attacks and complications. For colchicine-resistant patients, IL-1 antagonists like anakinra and canakinumab show promise, although their long-term benefits require further investigation. The present investigation underscores the importance of early diagnosis and integrated treatment approaches to improve patient outcomes, pain management, and quality of life.

The Role of the Advanced Practice Provider in a Pericardial Center of Excellence

Review

Author: Wensink, Emma ; Wang, Tom Kai Ming ; Agrawal, Ankit ; Heine, Mary ; Klein, Allan

AbstractPurpose of ReviewPericarditis can be a chronic and complex disease requiring years of treatment. These patients require close monitoring of labs, medications and their side effects, as well as virtual and inpatient follow up. Due to the complexity of this disease, many of these patients are treated for months and sometimes years. Our review highlights the role Advanced practice providers (APP) play in managing the complexity of these patients by providing efficient and quality care.Recent FindingsMulti-modality cardiac imaging is the cornerstone to the evaluation and treatment of pericardial diseases. The addition of Interleukin (IL-1) blockers or biologics (Rilonacept, Anakinra) in the last few years provides targeted therapy for these patients. Using imaging guided therapy (IGT) these complex patients require close, continuous follow up and monitoring as well as frequent medication titration.SummaryThe outcomes for these pericardial patients are improved with these centers due to the specialized medical and surgical care. Advanced Practice Providers play a vital role in a pericardial center with ordering the appropriate imaging and labs, handling medication titration, and providing patient education and continuity of care for these patients. They have been shown to decrease mortality, increase quality of care, and increase medication adherence.

Efficacy and safety of Anakinra in idiopathic recurrent pericarditis: Results from the UPACITER study

Article

Author: Sailler, Laurent ; Pugnet, Grégory ; Michaud, Martin ; Prudhomme, Laurent ; Castel, Brice ; Lemeu, Mélanie ; Vacheret, Fabienne

BACKGROUNDIdiopathic recurrent pericarditis (IRP) is a chronic autoinflammatory condition characterized by relapsing episodes of pericardial inflammation. Standard treatment involves colchicine and non-steroidal anti-inflammatory drugs (NSAIDs), with corticosteroids as a second-line therapy. However, many patients develop corticosteroid dependency or resistance, necessitating alternative treatments. Anakinra, an interleukin-1 (IL-1) receptor antagonist, has shown promising results as a third-line therapy.METHODSThe UPACITER multicenter study is a retrospective study conducted on patients with IRP and treated with anakinra between 2018 and 2024 in Midi-Pyrénées region of France. Patients met the 2015 ESC criteria for recurrent pericarditis. Clinical features, treatment responses, and side effects were collected. Primary endpoint was complete response, defined as the resolution of symptoms, normalization of C-reactive protein levels, and absence of pericardial effusion.RESULTSTwelve patients were included, with a median age of 46 years (interquartile range: 29.7-52.7). All patients achieved a complete response and corticosteroid discontinuation (from 17.9 ± 10.68 mg to 0 mg, p < 0.005). The recurrence-free survival rates were 100 % (95 % CI [100;100]) at month 6, 88.9 % (95 % CI [70.6;100]) at month 12, and 77.8 % (95 % CI [54.9;100]) at months 18 and 24. Three patients experienced a relapse of pericarditis: 2 during the spacing of injection and one after discontinuation of anakinra, with a median time before relapse of 12 months (IQR 9.5-13). One serious infection was reported.CONCLUSIONAnakinra is a safe and effective third-line therapy for patients with IRP resistant to conventional treatments, leading to a reduction in recurrences and corticosteroid discontinuation.

U.S. FDA grants interchangeable designation to YUFLYMA® (adalimumab-aaty), Celltrion's biosimilar to Humira® (adalimumab)

YUFLYMA ® (adalimumab-aaty) is a high-concentration (100mg/mL) and citrate-free formulation of Humira ® (adalimumab) biosimilar, that is now interchangeable [1] Interchangeable designation of YUFLYMA ® is supported by positive data from the Phase III interchangeability study in patients with moderate-to-severe plaque psoriasis INCHEON, South Korea, April 14, 2025 /PRNewswire/ -- Celltrion, Inc. today announced that the U.S. Food and Drug Administration (FDA) has designated YUFLYMA ® (adalimumab-aaty), as an interchangeable biosimilar to Humira ® (adalimumab). YUFLYMA is an FDA-approved, high-concentration (100mg/mL) and citrate-free formulation of Humira® biosimilar, approved for multiple inflammatory indications.[1] "With this new designation, YUFLYMA is further positioned to help more patients gain access to and afford the therapy they need," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. "YUFLYMA has the same dosage form, route of administration, and dosing regimen as the reference product. The pharmacist's ability to substitute the biosimilar directly at the pharmacy without the hassle of a new prescription and without the patient having to learn a new method of administration can be a game changer in increasing patient access to adalimumab." The interchangeable designation was supported by data from the Phase III interchangeability study, which demonstrated similar outcomes in terms of pharmacokinetics, efficacy, safety and immunogenicity in patients with moderately to severely active plaque psoriasis who received reference adalimumab (ADA) continuously and those who alternated between reference ADA and YUFLYMA during the dosing interval of Week 25-27. The result of the interchangeability study was presented at the European Academy of Dermatology & Venereology (EADV) 2024.[2] FDA-approved interchangeable biosimilars may be substituted for the reference product at the pharmacy without the intervention of the prescribing health care provider, subject to state laws.[3] The high-concentration form of YUFLYMA was FDA-approved in May 2023 and is currently available as 20mg, 40 mg and 80mg solution for injection in a prefilled syringe and in an autoinjector pen. YUFLYMA was introduced into the US commercial market on July 2, 2023. YUFLYMA is available in two pricing options to help provide more affordable options for patients. Adalimumab-aaty, the unbranded version, is priced at an 85% discount to the current wholesale acquisition cost (WAC) list price of Humira (adalimumab), providing economic benefits for patients and overall healthcare system. The branded version is priced at a 5% discount to the current WAC of Humira (adalimumab). Notes to Editors: About YUFLYMA® (CT-P17, biosimilar adalimumab-aaty)[1] YUFLYMA is the world's first proposed high-concentration, low-volume and citrate-free adalimumab biosimilar to receive European Commission approval. YUFLYMA is FDA approved for the treatment of patients with rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa and uveitis. YUFLYMA has been designated by the FDA as an interchangeable biosimilar in a prefilled syringe. YUFLYMA is a recombinant fully human anti–tumor necrosis factor α (anti-TNFα) monoclonal antibody. YUFLYMA is available in 20mg/0.2mL, 40mg/0.4mL and 80mg/0.8mL. IMPORTANT SAFETY INFORMATION[1] This important safety information also applies to YUFLYMA® (adalimumab-aaty) SERIOUS INFECTIONS Patients treated with adalimumab-aaty are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Discontinue adalimumab-aaty if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis (TB), including reactivation of latent TB. Patients with TB have frequently presented with disseminated or extrapulmonary disease. Test patients for latent TB before adalimumab-aaty use and during therapy. Initiate treatment for latent TB prior to adalimumab-aaty use. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Consider empiric antifungal therapy in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria. Carefully consider the risks and benefits of treatment with adalimumab-aaty prior to initiating therapy in patients with chronic or recurrent infection. Monitor patients closely for the development of signs and symptoms of infection during and after treatment with adalimumab-aaty, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Treatment with adalimumab-aaty should not be initiated in patients with an active infection, including localized infections. Patients over 65 years of age, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants (such as corticosteroids or methotrexate), may be at greater risk of infection. Discontinue adalimumab-aaty if a patient develops a serious infection or sepsis. For a patient who develops a new infection during treatment with adalimumab-aaty, closely monitor them, perform a prompt and complete diagnostic workup appropriate for an immunocompromised patient, and initiate appropriate antimicrobial therapy. Drug interactions with biologic products: In clinical studies in patients with RA, an increased risk of serious infections has been observed with the combination of TNF blockers with anakinra or abatacept, with no added benefit; therefore, use of adalimumab-aaty with abatacept or anakinra is not recommended in patients with RA. A higher rate of serious infections has also been observed in patients with RA treated with rituximab who received subsequent treatment with a TNF blocker. There is insufficient information regarding the concomitant use of adalimumab-aaty and other biologic products for the treatment of RA, PsA, AS, CD, UC, PS, and HS. Concomitant administration of adalimumab-aaty with other biologic DMARDs (e.g., anakinra and abatacept) or other TNF blockers is not recommended based upon the possible increased risk for infections and other potential pharmacological interactions. A higher rate of serious infections has been observed in RA patients treated with rituximab who received subsequent treatment with a TNF blocker. MALIGNANCY Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including adalimumab products. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including adalimumab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all of these patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to the use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants. Consider the risks and benefits of TNF blocker treatment including adalimumab-aaty prior to initiating therapy in patients with a known malignancy other than a successfully treated non-melanoma skin cancer (NMSC), or when considering continuing a TNF blocker in patients who develop a malignancy. In controlled portions of clinical trials of some adalimumab products, more cases of malignancies have been observed compared to control-treated adult patients. Non-melanoma skin cancer (NMSC) was reported during clinical trials for patients treated with adalimumab products. During the controlled portions of 39 global adalimumab clinical trials in adult patients with RA, PsA, AS, CD, UC, PS, HS and UV, the rate (95% confidence interval) of NMSC was 0.8 (0.52, 1.09) per 100 patient-years among adalimumab-treated patients and 0.2 (0.10, 0.59) per 100 patient-years among control-treated patients. Examine all patients, particularly those with a medical history of prior prolonged immunosuppressant therapy or psoriasis patients with a history of PUVA treatment, for the presence of NMSC prior to and during treatment with adalimumab-aaty. In clinical trials of some adalimumab products, there was an approximately threefold higher rate of lymphoma than expected in the general U.S. population. Patients with RA and other chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at a higher risk (up to severalfold) than the general population for the development of lymphoma, even in the absence of TNF blockers. Postmarketing cases of acute and chronic leukemia were reported with the use of a TNF blocker in RA and other indications. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving adalimumab were lymphomas; other cases represented a variety of different malignancies and included rare malignancies usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. HYPERSENSITIVITY Anaphylaxis and angioneurotic edema have been reported following administration of adalimumab products. If an anaphylactic or other serious allergic reaction occurs, immediately discontinue administration of adalimumab-aaty and institute appropriate therapy. HEPATITIS B VIRUS REACTIVATION Use of TNF blockers, including adalimumab-aaty, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. In some instances, HBV reactivation occurring in conjunction with TNF blocker therapy has been fatal. Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating TNF blocker therapy. Exercise caution in prescribing TNF blockers for patients identified as carriers of HBV and closely monitor such patients for clinical and laboratory signs of active HBV infection throughout therapy and for several months following termination of therapy. In patients who develop HBV reactivation, stop adalimumab-aaty and initiate effective antiviral therapy with appropriate supportive treatment. The safety of resuming TNF blocker therapy after HBV reactivation is controlled is not known. Therefore, exercise caution when considering resumption of adalimumab-aaty therapy in this situation and monitor patients closely. NEUROLOGIC REACTIONS Use of TNF blocking agents, including adalimumab products, has been associated with rare cases of new onset or exacerbation of clinical symptoms and/or radiographic evidence of central nervous system demyelinating disease, including multiple sclerosis (MS) and optic neuritis, and peripheral demyelinating disease, including Guillain-Barré syndrome. Exercise caution in considering the use of adalimumab-aaty in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders; discontinuation of adalimumab-aaty should be considered if any of these disorders develop. There is a known association between intermediate uveitis and central demyelinating disorders. HEMATOLOGIC REACTIONS Rare reports of pancytopenia including aplastic anemia have been reported with TNF blocking agents. Adverse reactions of the hematologic system, including medically significant cytopenia, have been infrequently reported with adalimumab products. Consider discontinuation of adalimumab-aaty therapy in patients with confirmed significant hematologic abnormalities. HEART FAILURE Cases of worsening congestive heart failure (CHF) and new-onset CHF have been reported with TNF blockers. Cases of worsening CHF have also been observed with adalimumab products. Exercise caution when using adalimumab-aaty in patients who have heart failure and monitor them carefully. AUTOIMMUNITY Treatment with adalimumab products may result in the formation of autoantibodies and, rarely, in the development of a lupus-like syndrome. If a patient develops symptoms suggestive of a lupus-like syndrome following treatment with adalimumab-aaty, discontinue treatment. IMMUNIZATIONS Patients on adalimumab-aaty may receive concurrent vaccinations, except for live vaccines. It is recommended that pediatric patients, if possible, be brought up to date with all immunizations in agreement with current immunization guidelines prior to initiating adalimumab-aaty therapy. No data are available on the secondary transmission of infection by live vaccines in patients receiving adalimumab products. The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live-attenuated) exposed infants. ADVERSE REACTIONS The most common adverse reactions in adalimumab clinical trials (>10%) were: infections (e.g., upper respiratory, sinusitis), injection site reactions, headache, and rash. INDICATIONS Adalimumab-aaty is a tumor necrosis factor (TNF) blocker indicated for: Rheumatoid Arthritis (RA): reducing signs and symptoms, inducing major clinical response, inhibiting the progression of structural damage, and improving physical function in adult patients with moderately to severely active RA Juvenile Idiopathic Arthritis (JIA): reducing signs and symptoms of moderately to severely active polyarticular JIA in patients 2 years of age and older Psoriatic Arthritis (PsA): reducing signs and symptoms, inhibiting the progression of structural damage, and improving physical function in adult patients with active PsA Ankylosing Spondylitis (AS): reducing signs and symptoms in adult patients with active AS Crohn's Disease (CD): treatment of moderately to severely active Crohn's disease in adults and pediatric patients 6 years of age and older Ulcerative Colitis (UC): treatment of moderately to severely active ulcerative colitis in adults Limitations of Use: Effectiveness has not been established in patients who have lost response to or were intolerant to TNF blockers Plaque Psoriasis (Ps): treatment of adult patients with moderate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy, and when other systemic therapies are medically less appropriate Hidradenitis Suppurativa (HS): treatment of adult patients with moderate to severe hidradenitis suppurativa Uveitis (UV): treatment of non-infectious intermediate, posterior, and panuveitis in adult patients For Yuflyma (adalimumab-aaty): Please click for Full U.S. Prescribing Information.

Kiniksa Pharmaceuticals Announces Development of KPL-387 in Recurrent Pericarditis and Updates Corporate Strategy

– Kiniksa plans to initiate a Phase 2/3 clinical trial of KPL-387 in recurrent pericarditis in mid-2025 – – KPL-387 Phase 1 single ascending dose data support potential monthly dosing – – Kiniksa continues to focus development on diseases with unmet need, prioritizing cardiovascular indications – – Kiniksa to discontinue abiprubart development in Sjögren’s Disease – LONDON, Feb. 25, 2025 (GLOBE NEWSWIRE) -- Kiniksa Pharmaceuticals International, plc (Nasdaq: KNSA) (Kiniksa), a biopharmaceutical company developing and commercializing novel therapies for diseases with unmet need, with a focus on cardiovascular indications, today announced the development program for KPL-387 in recurrent pericarditis and provided an update on its corporate strategy. KPL-387 is an independently developed monoclonal antibody that binds human interleukin-1 receptor 1 (IL-1R1), inhibiting the signaling activity of the cytokines interleukin-1α (IL-1α) and interleukin-1β (IL-1β). “Through the successful development and commercialization of ARCALYST, Kiniksa has helped thousands of patients suffering from recurrent pericarditis. Since the launch in 2021, we have generated over $800 million in product revenue and have become cash flow positive on an annual basis. We plan to further increase our penetration into the recurrent pericarditis population with ARCALYST,” said Sanj K. Patel, Chairman and Chief Executive Officer of Kiniksa. “We also continue to focus development on novel therapies for diseases with unmet need, prioritizing cardiovascular indications. Today, we are excited to extend our leadership in the recurrent pericarditis market through the development of KPL-387. We believe KPL-387 could expand the treatment options for recurrent pericarditis patients by providing a single monthly subcutaneous injection in a liquid formulation.” “KPL-387 could provide a meaningful addition to the therapeutic options available to patients suffering from recurrent pericarditis. Data generated from the single ascending dose portion of the ongoing Phase 1 study support our belief that KPL-387 could enable dosing with a single monthly subcutaneous injection in a liquid formulation,” said John F. Paolini, M.D., Ph.D., FACC, Chief Medical Officer of Kiniksa. “We have interacted with the FDA, and we plan to initiate a Phase 2/3 clinical trial of KPL-387 in recurrent pericarditis in mid-2025, with Phase 2 data expected in the second half of 2026.” Corporate Update Kiniksa continues to focus development on diseases with unmet need, prioritizing cardiovascular indications. Kiniksa is developing KPL-387, a fully human immunoglobulin G2 (IgG2) monoclonal antibody that binds IL-1R1, inhibiting the signaling of the cytokines IL-1α and IL-1β, in recurrent pericarditis with a target profile of monthly subcutaneous (SC) dosing. Kiniksa is conducting a single ascending dose (SAD) and multiple ascending dose Phase 1 clinical trial of KPL-387 in healthy volunteers. Topline data from the SAD portion of the Phase 1 trial of KPL-387 support potential monthly SC dosing in recurrent pericarditis. Kiniksa has interacted with the U.S. Food and Drug Administration (FDA) and expects to initiate a Phase 2/3 clinical trial of KPL-387 in recurrent pericarditis in mid-2025, with Phase 2 data expected in the second half of 2026. Kiniksa is advancing KPL-1161, an Fc-modified IgG2 monoclonal antibody that binds IL-1R1, inhibiting the signaling of the cytokines IL-1α and IL-1β, towards clinical development with a target profile of quarterly SC dosing. Kiniksa plans to discontinue the development of abiprubart in Sjögren’s Disease. The company will explore strategic alternatives for the asset. Kiniksa has exercised its right to terminate its exclusive license agreement for mavrilimumab with MedImmune. Kiniksa is conducting a single ascending dose (SAD) and multiple ascending dose Phase 1 clinical trial of KPL-387 in healthy volunteers. Topline data from the SAD portion of the Phase 1 trial of KPL-387 support potential monthly SC dosing in recurrent pericarditis.
