SUZHOU, China--(BUSINESS WIRE)-- Suzhou OSAI Biopharma, Inc., a biopharmaceutical company focused on developing live biotherapeutic products (LBPs), today announced that its Phase III clinical trial of vaginal L. crispatus live bacteria capsule (Lc262-1) has successfully met its primary and secondary endpoints. The Phase III study was a multicenter, randomized, double-blind, placebo-controlled trial that enrolled 320 patients with bacterial vaginosis (BV). After receiving seven days of oral metronidazole and vaginal LBP/placebo combination therapy, the cured patients were followed up for three months. The results from the treatment group were superior to the placebo group on the primary and secondary endpoints, with statistically significant differences between the two groups. In terms of safety, there was no difference in the incidence of adverse events or adverse reactions between the two groups. “The prevention of recurrent infection is critical in treating gynecological infections,” said Prof. Liu Zhaohui, MD, the principal investigator of the study and vice-chair of the Infection Working Group of the Chinese Medical Association's Department of Obstetrics and Gynecology, Capital Medical University Affiliated Beijing Obstetrics and Gynecology Hospital. “In China, more than 70 million BV cases are reported annually, with a 12-month recurrence rate of up to 60%. Currently, there are very limited effective treatments available. The positive results of this Phase III clinical trial have demonstrated the efficacy of L. crispatus in suppressing BV recurrence, providing patients with a new treatment option.” “Vaginal L. crispatus live bacteria capsule is a novel Live Biotherapeutic Product (LBP) that aims to restore healthy vaginal microbiota by using L. crispatus to prevent and reduce the recurrence of vaginal infections,” said Dr. Liu Yang, co-founder and chief scientific officer of Suzhou OSAI Biopharma. “This Phase III clinical trial is the first registrational Phase III clinical trial globally to evaluate the efficacy of L. crispatus in reducing BV recurrence under a rigorous clinical design. The observed data is encouraging, our team is committed to continuing to advance the program in regulatory registration and further expand our LBP pipeline.” About Vaginal L. crispatus Live Bacteria Capsule Vaginal L. crispatus live bacteria capsule is a first-in-class, innovative LBP developed by Suzhou OSAI Biopharma, utilizing live L. crispatus bacteria to restore the balance of the vaginal microbiome. L. crispatus is the most common and dominant bacteria in the vaginas of healthy Chinese women of childbearing age. The presence and enrichment of L. crispatus in the vaginal environment is considered a marker of healthy vaginal microbiota. L. crispatus can suppress the growth of other microorganisms through various mechanisms, such as maintaining a weakly acidic environment in the vagina by producing lactic acid, producing hydrogen peroxide, competing for nutrients (such as glycogen), occupying space (by competing for adhesion to vaginal epithelial cells) and stimulating local vaginal immunity. In recognition of the important role of L. crispatus in maintaining vaginal health, Suzhou OSAI Biopharma selected a strain of L. crispatus, Lc262-1, from the vaginal microbiota of healthy Chinese women. Leveraging its proprietary “Natural Microbiome Drug Development Platform,” the company developed a highly stable live bacteria capsule. About Bacterial Vaginosis Bacterial vaginosis (BV) is a common vaginal infection in women of childbearing age. It is caused by an overgrowth of anaerobic bacteria in the vagina. In China, there are over 70 million cases of BV each year. The recurrence rate of BV is high, roughly 20% within one month of treatment, 40% within three months of treatment, and 60% within 12 months of treatment. BV can also lead to pelvic inflammatory disease, post-surgical infections after gynecological surgery, and infertility. BV in pregnancy can lead to miscarriage, preterm birth, premature rupture of membranes, chorioamnionitis, neonatal infection, and postpartum infection. BV can also increase the risk of sexually transmitted infections (STIs), such as those caused by HPV, HIV, Neisseria gonorrhoeae, Chlamydia trachomatis, and herpes simplex virus type 2. About Suzhou OSAI Biopharma Founded in 2011, Suzhou OSAI Biopharma is a biopharmaceutical company focused on the research and development of LBPs. The company has built its own proprietary "Natural Microbiome Drug Development Platform" since its inception, with patents covering the Greater China Area, United States, Europe, Japan, South Korea, and Southeast Asia. OSAI Biopharma is committed to the research and development of LBPs to restore the healthy balance of human microbiome. Its lead asset, live L. crispatus capsule, has completed a Phase III clinical trial and demonstrated significant potential in the treatment and prevention of BV related to microbiota dysbiosis. OSAI Biopharma anticipates applying for Biologics License Applications (BLA) of its vaginal L. crispatus capsule to the China NMPA’s Center of Drug Evaluation (CDE) in the near future.

If Granted by the European Commission, Veklury will become the First and Only Authorized Antiviral Treatment Across All Stages of Renal Disease FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) granted a positive opinion for the use of Veklury® (remdesivir) in COVID-19 patients with severe renal impairment, including those on dialysis. The European Commission (EC) will review the CHMP recommendation and, if adopted, Veklury will become the first and only authorized antiviral COVID-19 treatment that can be used across all stages of renal disease. In Europe, approximately 75 million people suffer from chronic kidney disease (CKD). Patients with advanced CKD or end stage kidney disease (ESKD) represent a population that is highly vulnerable to COVID-19. They are at increased risk of morbidity and mortality from COVID-19, with mortality rates as high as 21-25%, and currently have limited treatment options that are safe and effective. “COVID-19 continues to pose a threat to the lives of vulnerable individuals, including those with renal impairment,” said Anu Osinusi, Vice President, Clinical Research for Hepatitis, Respiratory and Emerging Viruses, Gilead Sciences. “Gilead’s commitment to address the unmet needs of the most susceptible populations remains a top priority. We are encouraged by today’s CHMP opinion and will continue to invest in developing suitable treatment options for populations at risk of severe disease.” The clinical benefit of Veklury in hospitalized populations with COVID-19 is supported by randomized controlled trials, real-world evidence and meta-analyses, but its use has previously been restricted among patients with severe renal impairment (<30mL/min) due to insufficient data. This positive opinion for use in people with severe renal impairment was based on results from a Phase 1 Pharmacokinetic study (GS-US-540-9015), as well as results from the Phase 3 REDPINE trial that evaluated the safety of Veklury in patients hospitalized for COVID-19 with severe renal impairment. No new safety signals were observed in either of the studies. “The positive opinion from the Committee helps validate the safety pro Veklury in people with severe renal impairment,” said Prof. Dr. Tobias Welte, Professor of Pulmonary Medicine and Director of the Department of Pulmonary and Infectious Diseases at Hannover University School of Medicine. “Expanding the use of Veklury in this population, which still has limited treatment options, will help more people gain access to treatment for COVID-19.” In the European Economic Area (EEA), Veklury is the only antiviral indicated for both the treatment of COVID-19 in adult and adolescent patients who do not require supplemental oxygen and are at increased risk of developing severe COVID-19, as well as adults, adolescent and pediatric patients with pneumonia requiring supplemental oxygen (low- or high-flow oxygen or other non-invasive ventilation). About GS-US-540-5912 (REDPINE) Gilead conducted a Phase 3, randomized, double-blind, placebo-controlled parallel-group, multicenter study (REDPINE) evaluating the efficacy and safety of Veklury in patients with severely reduced kidney function who are hospitalized with COVID-19. The trial enrolled 243 hospitalized adult participants with confirmed COVID-19 and renal impairment who were randomized in a 2:1 manner to receive Veklury (n=163) or placebo (n=80), in addition to standard of care, and were stratified by ESKD, high-flow oxygen requirement, and region (US vs. ex-US). The study closed prematurely due to feasibility issues and was underpowered to assess for efficacy because of lower-than-expected enrollment. No new safety signals were observed in the study and no additional adverse reactions to Veklury were identified in 163 hospitalized patients with confirmed COVID-19 and acute kidney injury (AKI) (n=60), CKD (eGFR <30 mL/minute) (n=44) or ESKD (eGFR <15 mL/minute) requiring hemodialysis (n=59) receiving Veklury for up to 5 days. Pharmacokinetic data were obtained from the REDPINE study, as well as a Phase 1 open-label, parallel-group, single-dose study (GS-US-540-9015). Given the observed PK and the absence of any new safety signals associated with increased metabolite levels in patients with severely reduced kidney function, no dose adjustment of Veklury is recommended in patients with renal impairment, including those on dialysis. About Gilead’s COVID-19 Development Program Veklury (remdesivir) is a nucleotide analog invented by Gilead, building on more than a decade of the company’s antiviral research. Veklury is the antiviral standard of care for the treatment of hospitalized patients with COVID-19 and is a recommended treatment for reducing disease progression in non-hospitalized patients at high risk of disease progression. Veklury has an established safety pro minimal known drug interactions in diverse populations. It plays an important role in reducing disease progression and mortality across a spectrum of disease severity and enabling patients to recover faster. Veklury directly inhibits viral replication inside of the cell by targeting the SARS-CoV-2 viral RNA polymerase. Based on in vitro analyses, Veklury retains antiviral activity against recent Omicron subvariants of concern, including BQ.1.1 and XBB. Veklury is approved in more than 50 countries worldwide. To date, Veklury and generic remdesivir have been made available to nearly 13 million patients around the world, including more than 8 million people in middle- and low-income countries through Gilead’s voluntary licensing program. There remains a significant need to develop new and effective oral treatment options for people with COVID-19. Gilead is also working to advance an investigational oral antiviral, obeldesivir, for the treatment of COVID-19. Obeldesivir is a direct-acting nucleoside inhibitor of the of the SARS-CoV-2 RNA-dependent RNA polymerase (RdRp), a critical component that the virus uses to replicate. Once metabolized, obeldesivir works in the same way as Veklury to halt SARS-CoV-2 virus replication. U.S. Indication for Veklury Veklury® (remdesivir 100 mg for injection) is indicated for the treatment of COVID-19 in adults and pediatric patients (≥28 days old and weighing ≥3 kg) who are: Hospitalized, or Not hospitalized and have mild-to-moderate COVID-19 and are at high risk for progression to severe COVID-19, including hospitalization or death. For more information, please see the U.S. full Prescribing Information available at . U.S. Important Safety Information for Veklury Contraindication Veklury is contraindicated in patients with a history of clinically significant hypersensitivity reactions to Veklury or any of its components. Warnings and precautions Hypersensitivity, including infusion-related and anaphylactic reactions: Hypersensitivity, including infusion-related and anaphylactic reactions, has been observed during and following administration of Veklury; most occurred within one hour. Monitor patients during infusion and observe for at least one hour after infusion is complete for signs and symptoms of hypersensitivity as clinically appropriate. Symptoms may include hypotension, hypertension, tachycardia, bradycardia, hypoxia, fever, dyspnea, wheezing, angioedema, rash, nausea, diaphoresis, and shivering. Slower infusion rates (maximum infusion time up to 120 minutes) can potentially prevent these reactions. If a severe infusion-related hypersensitivity reaction occurs, immediately discontinue Veklury and initiate appropriate treatment (see Contraindications). Increased risk of transaminase elevations: Transaminase elevations have been observed in healthy volunteers and in patients with COVID-19 who received Veklury; these elevations have also been reported as a clinical feature of COVID-19. Perform hepatic laboratory testing in all patients (see Dosage and administration). Consider discontinuing Veklury if ALT levels increase to >10x ULN. Discontinue Veklury if ALT elevation is accompanied by signs or symptoms of liver inflammation. Risk of reduced antiviral activity when coadministered with chloroquine or hydroxychloroquine: Coadministration of Veklury with chloroquine phosphate or hydroxychloroquine sulfate is not recommended based on data from cell culture experiments, demonstrating potential antagonism, which may lead to a decrease in antiviral activity of Veklury. Adverse reactions The most common adverse reaction (≥5% all grades) was nausea. The most common lab abnormalities (≥5% all grades) were increases in ALT and AST. Drug interactions Drug interaction trials of Veklury and other concomitant medications have not been conducted in humans. Dosage and administration Administration should take place under conditions where management of severe hypersensitivity reactions, such as anaphylaxis, is possible. Treatment duration: For patients who are hospitalized, VEKLURY should be initiated as soon as possible after diagnosis of symptomatic COVID-19. For patients who are hospitalized and do not require invasive mechanical ventilation and/or ECMO, the recommended treatment duration is 5 days. If a patient does not demonstrate clinical improvement, treatment may be extended up to 5 additional days, for a total treatment duration of up to 10 days. For patients who are hospitalized and require invasive mechanical ventilation and/or ECMO, the recommended total treatment duration is 10 days. For patients who are not hospitalized, diagnosed with mild-to-moderate COVID-19, and are at high risk for progression to severe COVID-19, including hospitalization or death, the recommended total treatment duration is 3 days. VEKLURY should be initiated as soon as possible after diagnosis of symptomatic COVID-19 and within 7 days of symptom onset for outpatient use. Testing prior to and during treatment: Perform eGFR, hepatic laboratory, and prothrombin time testing prior to initiating VEKLURY and during use as clinically appropriate. Renal impairment: VEKLURY is not recommended in individuals with eGFR <30 mL/min. Pregnancy and lactation Pregnancy: A pregnancy registry has been established. There are insufficient human data on the use of Veklury during pregnancy. COVID-19 is associated with adverse maternal and fetal outcomes, including preeclampsia, eclampsia, preterm birth, premature rupture of membranes, venous thromboembolic disease and fetal death. Lactation: It is not known whether Veklury can pass into breast milk. Breastfeeding individuals with COVID-19 should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19.

FOSTER CITY, Calif.--( BUSINESS WIRE )--Gilead Sciences, Inc. (Nasdaq: GILD) today announced positive results from several COVID-19 clinical and real-world evidence studies being presented at the 33rd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID). A Phase 3 clinical study demonstrated that Veklury ® (remdesivir) was generally well tolerated in people with moderate to severe renal impairment. Additional data includes a retrospective real-world study which demonstrated that Veklury treatment is associated with a lower risk of death from COVID-19 for people living with cancer. A separate real-world analysis demonstrated that use of Veklury is also associated with reduced hospital readmission risk in immunocompromised patients hospitalized with COVID-19. Results from a Phase 1 study evaluating the safety, tolerability, and pharmacokinetics (PK) of obeldesivir, previously known as GS-5245, a novel investigational oral compound being developed by Gilead for the treatment of SARS-CoV-2 infection, showed obeldesivir reaches expected therapeutic plasma concentrations for the treatment of COVID-19. “ The breadth of clinical and real-world evidence data presented at ECCMID further support the strong efficacy and safety profile of Veklury,” said Frank Duff, MD, Senior Vice President, Virology Therapeutic Area Head, Gilead Sciences. “ Since the beginning of the pandemic, Veklury has played a critical role in the treatment of hospitalized patients with COVID-19. The real-world data further demonstrates its role in reducing mortality and hospital readmission rates in vulnerable patient populations, including people living with cancer and other immunosuppressed conditions.” Results from a Phase 3, randomized, double-blind, placebo-controlled, parallel-group, multicenter study (REDPINE) evaluated the safety of Veklury in patients with moderately and severely reduced kidney function who were hospitalized for COVID-19, a population with increased COVID-19-related mortality. The trial included 243 hospitalized adult participants with confirmed COVID-19 and renal impairment, including 90 participants (37%) with acute kidney injury (AKI), 64 participants (26%) with chronic kidney disease (CKD) and 89 participants (37%) with end stage kidney disease (ESKD) requiring hemodialysis. Patients were randomized 2:1 to receive Veklury (n=163) or placebo (n=80), in addition to standard of care. No new safety signals were observed in the study and no additional adverse reactions to Veklury were identified in 163 hospitalized patients with AKI (n=60), CKD (n=44) or ESKD (n=59) on hemodialysis receiving Veklury for up to 5 days. Two real-world studies of clinical practice presented at ECCMID examined Veklury’s effectiveness in reducing COVID-19-associated mortality for those living with cancer, as well as the role Veklury plays in reducing hospital readmission for immunocompromised patients infected with dominant variants of concern (VOC): pre-Delta, Delta and Omicron. In the first analysis, 7,482 people with cancer and hospitalized for COVID-19 who were treated with Veklury in the first two days of admission were evaluated. Results at Day 28 showed that people with cancer treated with Veklury had a significantly lower risk for mortality compared to people with cancer that were not treated with Veklury (HR:0.67, 95% CI:0.59-0.75; p<0.0001). This finding was seen across all VOC at Day 28: pre-Delta, 25% (HR:0.75, 95% CI:0.61-0.92; p=0.006); Delta, 32% (HR:0.68, 95% CI:0.55-0.85; p=0.0005); and Omicron, 40% (HR:0.60. 95% CI:0.50-0.72; p<0.0001). In the second analysis, 4,664 immunocompromised patients were evaluated and those who received treatment with Veklury (n=2,332) had lower risk for hospital readmission at both 30- and 60-day time periods. Results demonstrated that 60-day readmission rates were 16% lower for patients treated with Veklury during the Delta wave (HR:0.84, 95% CI:0.71-0.96; p<0.01) and 13% lower during the Omicron wave (HR:0.87, 95% CI:0.81-0.93; p<0.01) compared to matched controls (n=2,332). These data further confirm RWE presented at CROI earlier this year which demonstrated that use of Veklury was associated with a reduced risk of 30-day all-cause readmission. “ Antivirals play a key role in halting the replication of the SARS-CoV-2 virus. Remdesivir is also an important treatment option for vulnerable patient populations such as the immunocompromised, because it has a well-established safety and tolerability profile and it maintains activity across variants of concern,” said Michele Bartoletti, MD, PhD, Head of Infectious Disease Unit at Humanitas Research Hospital in Milan and Associate Professor of Humanitas University, Milan, Italy. Gilead also announced positive data at ECCMID from its Phase 1 randomized, double-blind, placebo-controlled, dose escalation study of obeldesivir in healthy adult participants. Results demonstrated that obeldesivir reaches expected therapeutic plasma concentrations for the treatment of COVID-19. Obeldesivir is an investigational novel oral antiviral being developed for the treatment of COVID-19, which once metabolized, works in the same way as Veklury by targeting SARS-CoV-2 virus replication through inhibition of the viral RNA polymerase. Gilead has advanced obeldesivir into two Phase 3 studies – BIRCH and OAKTREE – in broad populations and geographies to assess the efficacy and safety of obeldesivir for the treatment of non-hospitalized participants with COVID-19. About Gilead’s COVID-19 Development Program Veklury (remdesivir) is a nucleotide analog invented by Gilead, building on more than a decade of the company’s antiviral research. Veklury is the antiviral standard of care for the treatment of hospitalized patients with COVID-19 and is a recommended treatment for reducing disease progression in non-hospitalized patients at high risk of disease progression. Veklury has an established safety profile and minimal known drug interactions in diverse populations. It plays an important role in reducing disease progression and mortality across a spectrum of disease severity and enabling patients to recover faster. Complementing randomized clinical trials (RCTs) with these new real-world observational studies of hospitalized patients with COVID-19 further demonstrates the value of Veklury to clinicians and patients, including immunocompromised individuals and other vulnerable populations. Although RCTs remain the best tool for assessing the efficacy and safety of a medicine, RWE provides important complimentary data on a treatment’s use in routine clinical practice. RWE analyses of Veklury from other sources are ongoing and may vary in their results or conclusions. The clinical benefits of Veklury in hospitalized patients have been established in multiple randomized, controlled Phase 3 clinical trials, including ACTT-1. In 2020, results from ACTT-1 demonstrated that in the overall study population of hospitalized patients with COVID-19, Veklury-treated patients showed a trend toward reduced mortality compared with placebo (11% vs. 15%, HR:0.73, 95% CI:0.52 to 1.03); however, this result was not statistically significant. Veklury is approved in more than 50 countries worldwide. To date, Veklury and generic remdesivir have been made available to nearly 13 million patients around the world, including more than 8 million people in middle- and low-income countries, through Gilead’s voluntary licensing program. These licenses currently remain royalty-free, reflecting Gilead’s existing commitment to enabling broad patient access to remdesivir. There remains a significant need to develop new and effective oral treatment options for people with COVID-19. Gilead is also working to advance an investigational oral nucleoside prodrug, obeldesivir, that when metabolized forms the same active metabolite as remdesivir. About BIRCH (NCT05603143) BIRCH is a Phase 3, global, randomized, double-blind, placebo-controlled study that will compare the efficacy and safety of obeldesivir with placebo in non-hospitalized participants who are at high risk for developing severe COVID-19. For further information, please see https://www.clinicaltrials.gov/ct2/show/NCT05603143 . About OAKTREE (NCT05715528) OAKTREE is a Phase 3, global, randomized, double-blind, placebo-controlled study that will evaluate participants without risk factors for developing severe COVID-19 to compare the safety and efficacy of obeldesivir with placebo in non-hospitalized participants with COVID-19, regardless of vaccination status. For further information, please see https://clinicaltrials.gov/ct2/show/NCT05715528 . Obeldesivir is an investigational product that has not been approved for any use globally.
