Younger patients in the U.S. can now benefit from Grifols Fibrin Sealant (FS) and its positive effect on surgical outcomes, including a fast time to hemostasisGrifols surgical bleeding management treatments form part of an increasingly robust portfolio of innovative therapeutics enhancing the health and well-being of patients BARCELONA, Spain, Oct. 29, 2024 (GLOBE NEWSWIRE) -- Grifols (MCE:GRF, MCE:GRF.P, NASDAQ:GRFS), a global healthcare company and leading manufacturer of plasma-derived medicines, today announced that its plasma-protein based fibrin sealant (FS) for controlling surgical bleeding has received approval from the United States Food and Drug Administration (FDA) for pediatric patients. The U.S. indication for children and adolescents extends the availability of FS, which is already approved for this patient segment in Europe, in addition to adults. During surgery Grifols FS promotes hemostasis and tissue sealing, resulting in reduced blood loss and potentially fewer complications. Grifols FS biosurgery treatment is commercialized as VISTASEAL™ in the U.S. and Canada, and VERASEAL™ in Europe and elsewhere. Both brands are marketed and distributed by Johnson & Johnson MedTech, as part of a strategic collaboration between the two companies announced in 2019. Grifols FS combines two plasma proteins, fibrinogen and thrombin, and is applied with Johnson & Johnson MedTech’s airless spray technology to rapidly form clots. The FS solution is now available in 18 countries. In early 2023, Grifols announced that it had met all primary and secondary endpoints of its phase 3b study evaluating the administration of Grifols FS to pediatric patients, defined as those not having reached 18 years of age. Researchers conducted a global prospective, randomized, active-controlled, single-blind, parallel group clinical trial designed to evaluate the safety and efficacy of the FS as an adjunct to hemostasis during surgery in pediatric patients (compared with an active control). The study included a total of 178 patients enrolled and treated across 18 recruitment centers. A greater than 95% efficacy rate was achieved in both treatment arms, with hemostasis within four minutes of application. In addition, Grifols FS demonstrated a good safety and tolerability profile, as the distribution of adverse events was comparable between arms. “Developing innovative biosurgery solutions reflects Grifols’ ability to provide patients with more medicines across many therapeutic areas to enhance their well-being,” said Joerg Schuettrumpf, Grifols Chief Scientific Innovation Officer. It’s estimated that between roughly one-third and two-thirds of open surgeries experience disruptive bleeding,1 while challenging and uncontrollable bleeding during surgery is associated with high mortality rates.1,2 About VISTASEAL VISTASEAL is a single-use product that uses a combination of human fibrinogen and human thrombin to assist with mild to moderate bleeding control when standard surgical techniques such as suture or cautery are ineffective. The sealant is applied in a thin layer over the bleeding tissue in order to generate a cross-linked fibrin clot to achieve hemostasis. VISTASEAL can be utilized in high-risk patients when there are concerns regarding coagulopathy, antiplatelets, anticoagulants, and friable tissue. VISTASEAL™ Fibrin Sealant (Human) IMPORTANT SAFETY INFORMATION INDICATIONVISTASEAL™, a fibrin sealant, is indicated as an adjunct to hemostasis for mild to moderate bleeding in patients undergoing surgery when control of bleeding by standard surgical techniques (such as suture, ligature, and cautery) is ineffective or impractical. VISTASEAL™ is effective in heparinized patients. CONTRAINDICATIONSDo not inject directly into the circulatory system. Do not use for the treatment of severe or brisk arterial bleeding.Do not use in patients with history of anaphylaxis or severe systemic reactions to human blood products.Do not use VISTASEAL™ for spraying unless the minimum recommended distance from the applicator tip to the bleeding site can be achieved. WARNINGS AND PRECAUTIONS Thromboembolic events may occur if VISTASEAL™ is administered intravascularly. Hypersensitivity reactions can occur. May carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. ADVERSE REACTIONSThe most common adverse reactions (reported in >1% of patients) were procedural pain, and nausea.

Additional real-world studies show sustained HAE attack rate reduction after initiating ORLADEYO, regardless of C1-INH status, and patient preference for an oral LTP therapyRESEARCH TRIANGLE PARK, N.C., Oct. 24, 2024 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced new real-world comparative research on the use of oral, once-daily ORLADEYO® (berotralstat) that found high rates of adherence and persistence for ORLADEYO, similar to the rates observed with two other long-term prophylactic (LTP) therapies for hereditary angioedema (HAE). The company also announced new real-world evidence showing statistically significant and sustained HAE attack rate reductions after initiating ORLADEYO in patients with HAE, regardless of their C1-inhibitor (C1-INH) deficiency status, and new findings from an HAE patient survey confirming patient preference for an oral LTP therapy. “These results build on previous research that highlights how the real-world effectiveness and convenience of our oral, once-daily prophylactic therapy are differentiators for patients. The strong adherence, persistence and preference for ORLADEYO we report here provide further evidence that enables physicians to optimize individualized treatment recommendations for each of their patients. We continue to generate real-world evidence demonstrating that ORLADEYO is a powerful, potentially life-changing treatment for many people with HAE,” said Dr. Donald S. Fong, chief medical officer of BioCryst. The data are being presented at the Annual Scientific Meeting of the American College of Allergy, Asthma & Immunology (ACAAI), which is taking place in Boston from October 24-28, 2024. High Adherence and Persistence Rates for ORLADEYO and Other LTP Therapies Poster #R072 explores adherence and persistence rates among patients with HAE following initiation of ORLADEYO (n=90) compared with lanadelumab (n=189) and subcutaneous plasma-derived C1-inhibitor (SC-pdC1-INH) (n=78). “Our findings reveal that among HAE patients managed with LTP, high adherence and persistence rates were demonstrated for ORLADEYO. There was a striking consistency between first line therapies with comparable results for lanadelumab and SC-pdC1-INH. ORLADEYO rates were equivalent to – and in some cases better than – these LTP counterparts. The outcomes of our study provide further support for a shared decision-making approach within the physician-patient partnership to inform LTP selection, incorporating effectiveness, safety, treatment burden and patient preference for each individual,” said Sandra Christiansen, MD, professor of medicine and director of translational research at the US HAEA Angioedema Center at the University of California, San Diego. Adherence And Persistence Among Hereditary Angioedema Patients Treated With Berotralstat, Lanadelumab, And Subcutaneous Plasma-Derived C1-Inhibitor; ePoster #R072; Friday, October 25, 2:30-2:45 p.m. ET; Monitor #19, Hall A Eighty-six percent of patients who took ORLADEYO (n=77), 91 percent who took lanadelumab (n=172) and 83 percent who took SC-pdC1-INH (n=65) filled at least two prescriptions during the 12-month follow-up period.Adherence rates among patients with at least two fills were high at 12 months of follow-up. Seventy-seven percent of patients taking ORLADEYO were adherent compared to 76 percent of patients taking lanadelumab and 80 percent of patients taking SC-pdC1-INH.Persistence rates among patients with at least two fills were high at 12 months of follow-up, with 71 percent of patients taking ORLADEYO persistent compared to 63 percent of patients taking lanadelumab and 63 percent of patients taking SC-pdC1-INH.No statistically significant differences in adherence or persistence were observed between the LTP patient cohorts. Methods Electronic health records linked to claims data were used to select mutually exclusive cohorts of patients aged 12 and above who initiated ORLADEYO, lanadelumab or pdC1-INH between June 22, 2017, and September 12, 2023.Adherence was defined as having a proportion of days covered greater than or equal to 0.80.Persistence was defined as fewer than 45 consecutive days without the index LTP treatment. Sustained HAE Attack Rate Reduction After Beginning ORLADEYO Regardless of C1-INH Status Posters #R092 and #R093 evaluate self-reported HAE attacks prior to and following ORLADEYO initiation among patients with and without HAE with C1-inhibitor deficiency (HAE-nl-C1-INH), respectively. “ORLADEYO was associated with statistically significant and sustained reductions in attack rates through 18 months (540 days) following ORLADEYO initiation, regardless of patients’ C1-INH status. Importantly, in this real-world study, patients with zero attacks at baseline were included, compared to the minimum of two attacks that was required at baseline in APeX-2. These data confirm that many already well-controlled HAE patients enjoy continued or improved attack control once they initiate ORLADEYO,” Dr. Fong added. Sustained Real-World Attack Reductions Following Berotralstat Initiation Among Patients with Hereditary Angioedema with C1-Inhibitor Deficiency; ePoster #R092; Friday, October 25, 3:30-3:45 p.m. ET; Monitor #20, Hall A Patients (n=466) had significantly lower attack rates at each follow-up interval, which ranged from 0.62 attacks per month at days 361-450 (n=185) to 0.79 at days 271-360 (n=217) versus baseline (2.62 at days 361-450 to 2.50 at days 271-360).Mean monthly attack rate reduction was -1.71 (p<0.05) at days 271-360 (n=217) and -1.96 (p<0.05) at days 451-540 (n=157). Sustained Real-World Attack Reductions Following Berotralstat Initiation Among Patients with Hereditary Angioedema without C1-Inhibitor Deficiency; ePoster #R093; Friday, October 25, 3:45-4:00 p.m. ET; Monitor #20, Hall A Patients (n=353) had significantly lower attack rates at each follow-up interval, which ranged from 1.63 attacks per month at days 181-270 (n=191) to 2.04 at days 1-90 (n=304) versus baseline (4.33 at days 181-270 to 4.63 at days 1-90).Mean monthly attack rate reduction was -2.91 (p<0.05) at days 271-360 (n=157) and -2.53 (p<0.05) at days 451-540 (n=108). Methods Outcomes were collected through BioCryst’s sole-source pharmacy and included U.S. patients who actively received ORLADEYO 110 or 150 mg QD from December 15, 2020, to January 8, 2024.Patient-reported HAE attack rates were collected at baseline and each refill (approximately every 30 days).To be included in the analysis of a given follow-up period, patients were required to have responded to a follow-up assessment within the period of interest and to the onboarding self-assessment of attacks. Approximately 96 percent of patients met these criteria at each interval. Patients with HAE Prefer Oral LTP Poster #R081 examines the LTP treatment preferences of patients with HAE, as collected through an online survey. “We are encouraged to see both effectiveness and convenience are drivers of treatment preference with patients preferring oral therapy over injectable therapy when efficacy is assumed equal. Given the benefits of treatment with ORLADEYO for patients who remain on therapy over the long term, we believe we will continue to see the preference towards oral therapy reflected in the strong commercial performance of our oral, once-daily prophylactic therapy for HAE,” Dr. Fong noted. Long-Term Prophylactic Treatment Preferences of Patients With Hereditary Angioedema; ePoster #R081; Friday, October 25, 4:45-5:00 p.m. ET; Monitor #19, Hall A LTP treatment attributes rated most important were effectiveness in attack prevention and effectiveness in reducing attack severity.When presented with the option of an equally effective oral or injectable LTP, 54 percent preferred an oral daily therapy over a biweekly or monthly subcutaneous injection.More than half (52 percent) preferred oral over injectable LTP as infrequently as every three months. Methods Results from an online survey of U.S. patients with HAE who were at least 18 years of age, self-reported their diagnosis and were receiving an HAE treatment (LTP, on-demand or both) or had experienced at least one HAE attack in the preceding three months (n=150). In addition to displaying in the exhibit hall at the noted times, ePosters are accessible online and on demand to registered attendees on ACAAI’s website. About ORLADEYO® (berotralstat)ORLADEYO® (berotralstat) is the first and only oral therapy designed specifically to prevent attacks of hereditary angioedema (HAE) in adult and pediatric patients 12 years and older. One capsule of ORLADEYO per day works to prevent HAE attacks by decreasing the activity of plasma kallikrein. U.S. Indication and Important Safety Information INDICATIONORLADEYO® (berotralstat) is a plasma kallikrein inhibitor indicated for prophylaxis to prevent attacks of hereditary angioedema (HAE) in adults and pediatric patients 12 years and older. Limitations of useThe safety and effectiveness of ORLADEYO for the treatment of acute HAE attacks have not been established. ORLADEYO should not be used for the treatment of acute HAE attacks. Additional doses or dosages of ORLADEYO higher than 150 mg once daily are not recommended due to the potential for QT prolongation. IMPORTANT SAFETY INFORMATION An increase in QT prolongation was observed at dosages higher than the recommended 150 mg once-daily dosage and was concentration dependent. The most common adverse reactions (≥10% and higher than placebo) in patients receiving ORLADEYO were abdominal pain, vomiting, diarrhea, back pain, and gastroesophageal reflux disease. A reduced dosage of 110 mg taken orally once daily with food is recommended in patients with moderate or severe hepatic impairment (Child-Pugh B or C). Berotralstat is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein. P-gp inducers (eg, rifampin, St. John’s wort) may decrease berotralstat plasma concentration, leading to reduced efficacy of ORLADEYO. The use of P-gp inducers is not recommended with ORLADEYO. ORLADEYO at a dose of 150 mg is a moderate inhibitor of CYP2D6 and CYP3A4. For concomitant medications with a narrow therapeutic index that are predominantly metabolized by CYP2D6 or CYP3A4, appropriate monitoring and dose titration is recommended. ORLADEYO at a dose of 300 mg is a P-gp inhibitor. Appropriate monitoring and dose titration is recommended for P-gp substrates (eg, digoxin) when coadministering with ORLADEYO. The safety and effectiveness of ORLADEYO in pediatric patients <12 years of age have not been established. There are insufficient data available to inform drug-related risks with ORLADEYO use in pregnancy. There are no data on the presence of berotralstat in human milk, its effects on the breastfed infant, or its effects on milk production.

Data to be highlighted in a Distinguished Industry Oral Abstract presentation at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Scientific Meeting SAN DIEGO, Oct. 24, 2024 /PRNewswire/ -- Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage allogeneic cell therapy and genetic medicines company advancing differentiated non-viral treatments for patients with cancer, autoimmune, and rare diseases, today announced the upcoming presentation of new preclinical data supporting the potential of P-KLKB1-101, a liver-directed genetic medicine that uses the Company's Cas-CLOVER™ Site-Specific Gene Editing System, for the treatment of patients with hereditary angioedema (HAE). The data showed high-fidelity KLKB1 gene editing for the targeted correction of HAE, the ability for controlled dose response, favorable tolerability and liver editing within the predicted therapeutic range. "The newest preclinical data for P-KLKB1-101 support our goal to develop a gene editing treatment option for HAE with encouraging early tolerability, safety and efficacy results," said Blair Madison, Ph.D., Chief Scientific Officer, Gene Therapy at Poseida Therapeutics. "We achieved a highly effective, therapeutically relevant reduction of kallikrein in our new humanized pre-clinical mouse model at a low 0.125 mg/kg dose, marking an improvement in our lipid nanoparticle delivery efficiency. These tools could potentially enable therapeutic gene editing in other liver-relevant targets, considering the high fidelity editing of Cas-CLOVER and the promising delivery efficiency we are seeing with our proprietary lipid and LNP in pre-clinical studies." HAE is a rare inherited disorder characterized by recurrent episodes of fluid accumulation outside of blood vessels, causing rapid swelling of tissues. The swelling is caused by unchecked activation of the kallikrein-bradykinin cascade due to deficiency of the C1 esterase inhibitor, a protein that is involved in regulating vascular permeability and the contact system. Patients with HAE are in need of a durable, effective, and convenient treatment option that eliminates recurrent attacks. P-KLKB1-101 is a fully non-viral investigational gene editing therapy designed to enable high fidelity editing at the pre-kallikrein gene, or KLKB1, for correction of HAE. It utilizes the Cas-CLOVER nuclease, which is engineered for high specificity, to achieve site-specific gene editing. Key Highlights from P-KLKB1-101 Data to be Presented at ACAAI P-KLKB1-101 enabled highly efficient KLKB1 editing and reduction of kallikrein in cultured primary human hepatocytes, with all off-target edits consistently at or below 0.1%, including at high dose levels. P-KLKB1-101 yielded controlled, dose-dependent reductions in kallikrein protein levels and activity in a new humanized mouse model. The reduction in plasma kallikrein levels was stable and persisted for at least 180 days (latest time point assessed). In this model, the targeted therapeutic level of KLKB1 editing was achieved with a single dose, and a 58% reduction of kallikrein levels at the minimally effective dose of 0.125 mg/kg. Interim non-human primate (NHP) data demonstrate that P-KLKB1-101 had favorable tolerability and achieved liver editing approaching the desired therapeutic range. Ongoing lead optimization of P-KLKB1-101 yielded a 29% increase in potency (as measured by on-target KLKB1 editing) relative to a historical dose-matched benchmark. Poseida's novel ionizable lipid and lipid nanoparticle (LNP) enables potent in vivo delivery of P-KLKB1-101 and a controlled dose response. Presentation Details The data will be presented on Saturday, October 26 by Dr. Madison at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Scientific Meeting in Boston: Title: Highly Specific Non-Viral Gene Editing with P-KLKB1-101 for Hereditary Angioedema Abstract #: 8063 Session: Distinguished Industry & Late-breaking Oral Abstracts – Session 1 Session Date/Time: Saturday, October 26, 4:30-6:00 p.m. ET (presentation at 5:03 p.m. ET) About P-KLKB1-101 P-KLKB1-101 is an investigational liver-directed non-viral gene editing approach designed using the Cas-CLOVER™ Site-Specific Gene Editing System, Poseida's proprietary high-fidelity nuclease. P-KLKB1-101 is designed for site-specific gene editing of the KLKB1 gene for the treatment of hereditary angioedema (HAE). This rare inherited disorder results in the swelling of the skin, intestinal tract, and airways, which can be both debilitating and life-threatening. Preclinical data demonstrates therapeutically relevant reduction of pre-kallikrein levels in both mouse and non-human primate models. About Cas-CLOVER The Cas-CLOVER™ Site-Specific Gene Editing System employs dual RNA-guided DNA targeting for high fidelity editing. The dual guide RNA targeting provides spatial restrictions on each of two Cas-CLOVER molecules after interacting with specific DNA sequences. This interaction then allows Clo051 cutting at the target site. The result is a highly specific edit by the Cas-CLOVER nuclease, and a low incidence of unwanted off-target edits, with 25-fold greater fidelity than CRISPR/Cas9. About Poseida Therapeutics, Inc. Poseida Therapeutics is a clinical-stage biopharmaceutical company advancing differentiated allogeneic cell therapies and genetic medicines with the capacity to cure. The Company's pipeline includes investigational allogeneic CAR-T cell therapies for hematologic cancers, autoimmune diseases, and solid tumors, as well as investigational in vivo genetic medicines that address patient populations with high unmet medical need.
