Primary Ovarian Insufficiency

– Three Oral Presentations and 30 Posters Across HBV, HCV, HDV, and Fibrosis, Including Late-Breaking Data on Hepcludex® (bulevirtide) in HDV, Demonstrate Gilead’s Commitment to Addressing Unmet Needs for People Living with Liver Disease – – Studies Evaluate Safety and Efficacy of Hepcludex® (bulevirtide) in People Living with Chronic HDV – FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced the presentation of new viral hepatitis data at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting®, from November 10-14, 2023. Key findings from more than 80 presentations will include a late-breaker oral presentation of primary endpoint results from the Phase 2b MYR204 study evaluating Hepcludex® (bulevirtide), an investigational therapy in the U.S. and outside of the European Economic Area, in combination with pegylated interferon alfa-2a (PegIFNα) in patients with chronic hepatitis delta virus (HDV), and an integrated analysis of Week 96 data from pivotal Phase 2b and Phase 3 studies evaluating the efficacy and safety of bulevirtide monotherapy. Gilead will also present long-term (8-year) results from ongoing studies of Vemlidy® (tenofovir alafenamide, TAF) in chronic hepatitis B (HBV), two-year efficacy, safety, and resistance data on TAF in pediatric patients with chronic HBV. In the U.S., Vemlidy is indicated for the treatment of chronic HBV in adults and pediatric patients 12 years of age and older with compensated liver disease. The use of Vemlidy for other patient populations is investigational, and the safety and efficacy for these uses have not been established. Additionally, real-world data on efforts that support the World Health Organization’s (WHO) HBV and hepatitis C (HCV) elimination goals will be presented. These latest data demonstrate the company’s ongoing efforts to address the unmet needs of people affected by viral hepatitis. “We look forward to sharing our latest findings in the treatment of people living with HDV with the broader liver community at The Liver Meeting,” said Anu Osinusi, Vice President Clinical Research for Hepatitis, Respiratory and Emerging Viruses at Gilead Sciences. “Despite meaningful advances in the treatment of people living with viral hepatitis, much work remains to improve diagnosis, care, and services to address the unmet needs of people living with viral hepatitis and pursue our continued commitment to help achieve HBV and HCV elimination goals by 2030.” Driving Innovation in HDV Treatment A leader in HDV research, Gilead will present late-breaking primary endpoint data from the Phase 2b MYR 204 study assessing the safety and efficacy of bulevirtide in combination with PegIFN (Oral LBP- 5009). Separately, data from a pooled analysis from the MYR204 study and the Phase 3 MYR301 (Oral 63) study on improved virologic and biochemical response by Week 96 with continued treatment with bulevirtide in those who were early non- and partial responders at Week 24 (Oral 63) will be presented. Data on the improvement in noninvasive tests regardless of virologic response in patients receiving bulevirtide for 96 weeks will also be presented (Poster 1473-C). In July 2023, the EMA granted full Marketing Authorization (MA) for bulevirtide. Bulevirtide was initially granted conditional MA from the EMA in July 2020 to provide access to people living with HDV urgent access to treatment. In the U.S. and outside of the European Economic Area, bulevirtide is an investigational agent. In these regions, health authorities have not established the safety and efficacy of bulevirtide.

Please see below for the U.S. Indication and Important Safety Information, including BOXED WARNING, for Vemlidy. U.S. Important Safety Information and Indication for Vemlidy BOXED WARNING: POST TREATMENT SEVERE ACUTE EXACERBATION OF HEPATITIS B Discontinuation of anti-hepatitis B therapy, including VEMLIDY, may result in severe acute exacerbations of hepatitis B. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy, including VEMLIDY. If appropriate, resumption of anti-hepatitis B therapy may be warranted. WARNINGS AND PRECAUTIONS Risk of Development of HIV-1 Resistance in HBV/HIV-1 Coinfected Patients: Due to this risk, VEMLIDY alone should not be used for the treatment of HIV-1 infection. Safety and efficacy of VEMLIDY have not been established in HBV/HIV-1 coinfected patients. HIV antibody testing should be offered to all HBV-infected patients before initiating therapy with VEMLIDY, and, if positive, an appropriate antiretroviral combination regimen that is recommended for HBV/HIV-1 coinfected patients should be used. New Onset or Worsening Renal Impairment: Postmarketing cases of renal impairment, including acute renal failure, proximal renal tubulopathy (PRT), and Fanconi syndrome have been reported with TAF-containing products. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue VEMLIDY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Monitor renal function in all patients – See Dosage and Administration. Lactic Acidosis and Severe Hepatomegaly with Steatosis: Fatal cases have been reported with the use of nucleoside analogs, including tenofovir disoproxil fumarate (TDF). Discontinue VEMLIDY if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations. ADVERSE REACTIONS Most common adverse reactions (incidence ≥5%; all grades) in all clinical studies through week 144 were headache, upper respiratory tract infection, abdominal pain, cough, back pain, arthralgia, fatigue, nausea, diarrhea, dyspepsia, and pyrexia. DRUG INTERACTIONS Coadministration of VEMLIDY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of tenofovir and the risk of adverse reactions. Coadministration of VEMLIDY is not recommended with the following: oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, or St. John’s wort. Such coadministration is expected to decrease the concentration of tenofovir alafenamide, reducing the therapeutic effect of VEMLIDY. Drugs that strongly affect P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) activity may lead to changes in VEMLIDY absorption. Consult the full prescribing information for VEMLIDY for more information on potentially significant drug interactions, including clinical comments. DOSAGE AND ADMINISTRATION Testing Prior to Initiation: HIV infection. Prior to or When Initiating, and During Treatment: On a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Dosage: 1 tablet taken once daily with food. Renal Impairment: Not recommended in patients with end stage renal disease (ESRD; eCrCl <15 mL/min) who are not receiving chronic hemodialysis; in patients on chronic hemodialysis, on hemodialysis days, administer VEMLIDY after completion of hemodialysis treatment. No data are available to make dose recommendations in pediatric patients with renal impairment. Hepatic Impairment: Not recommended in patients with decompensated (Child-Pugh B or C) hepatic impairment. INDICATION VEMLIDY is indicated for the treatment of chronic hepatitis B virus (HBV) infection in adults and pediatric patients 12 years of age and older with compensated liver disease. About HDV Chronic hepatitis delta virus (HDV) is the most severe form of viral hepatitis and can have mortality rates as high as 50% within five years in cirrhotic patients. HDV occurs only as a co-infection in individuals who have hepatitis B virus (HBV). It is estimated that at least 12 million people worldwide are likely currently co-infected with HDV and HBV. HDV co-infection is associated with a faster progression to liver fibrosis, cirrhosis, hepatic decompensation and an increased risk of liver cancer and death. In the U.S. and Europe, there are approximately more than 230,000 people living with HDV; however, it remains underdiagnosed globally.

Quadrant Laboratories' Fragile X Syndrome test is now approved by the New York State Department of Health and is available in all 50 states SYRACUSE, N.Y., Oct. 17, 2023 /PRNewswire/ -- Quadrant Laboratories announced today that its Syracuse-based lab has been approved by the New York State Department of Health for genetic testing. This is in conjunction with the NYSDOH approval of Quadrant's Fragile X Syndrome (FXS) test, which is now available for physicians to order in all 50 states. Quadrant's FXS test uses a saliva swab as a primary collection, rather than a blood draw, and can be collected in the patient's home before getting shipped back to be tested in Quadrant's CLIA/CLEP certified clinical lab. Continue Reading Dr. Funda Suer, EVP of Clinical Diagnostics and Clinical Laboratory Director for Quadrant Laboratories, said, "In both the pediatric and adolescent populations, we found it was much easier to collect saliva versus blood. Additionally, saliva serves as an excellent source of the genetic material essential for conducting an accurate test to identify Fragile X Syndrome, as well as other Fragile X-related disorders such as Fragile X-associated Tremor/Ataxia Syndrome (FXTAS) and Fragile X-associated Primary Ovarian Insufficiency (FXPOI), as well as carrier screening." Fragile X Syndrome is one of the most common genetic causes of intellectual disability. This genetic condition is caused by changes in the FMR1 gene, which is responsible for creating a protein crucial in brain development. Following the discovery of the association between the FMR1 gene and FXS, gene-specific testing has made identifying the condition significantly more accurate. Bryan Greene, CEO of Quadrant Laboratories, said, "Testing for Fragile X syndrome identifies over 99% of individuals with the syndrome and identifies carriers of the FMR1 premutation." Based on recommendations from American Academy of Pediatrics, any child who presents with a developmental delay, a diagnosis of autism without a specific etiology, borderline intellectual abilities, or has a family history of FXS should undergo genetic testing for Fragile X Syndrome.

Phalguni Deswal @Phalguni_GD Data breaches cost the companies an average of $5m to remediate, as per IBM’s 2020 data breach report. Image Credit: Michael Vi / Shutterstock. IBM has announced a data breach of Janssen’s CarePath platform and has started informing affected customers. The Janssen CarePath portal provides patients and healthcare professionals in the US with information regarding insurance coverage, out-of-pocket costs, and prescribing information at no cost to the users. Recommended Reports Reports Premature Ovarian Failure Drugs in Development by Stages, Target, MoA, RoA, Molecule Type and Key... GlobalData Reports Bronchiolitis Obliterans Drugs in Development by Stages, Target, MoA, RoA, Molecule Type and Key ... GlobalData View all The number of highest grossing Janssen drugs are included in the platform such as Darzalex (daratumumab) and Stelara (ustekinumab) which generated $2.5bn and $3.2bn in US sales in H1 2023, respectively, as per the company’s Q2 2023 financial report . Data breaches at the top pharma companies are nothing new, as companies such as Merck & Co (MSD), Roche, and AstraZeneca have all been hacked in the past. Data breaches cost the companies an average of $5m to remediate, as per IBM’s 2020 data breach report . The Janssen CarePath systems provider, IBM, indicated that the stolen data may have contained information provided as part of the Janssen CarePath application, including individual names, contact information, date of birth, health insurance information, and information on an individual’s health conditions and medications. Although IBM has identified that a data breach occurred on 2 August, the company is unsure of the extent of information that was accessed. IBM was quick to note that no financial information or social security numbers have been affected, as it was not part of the database, and no information misuse has been reported. However, the companies have offered the affected customers a complimentary one-year credit monitoring service. IBM noted the data breach as part of its investigation into a potential backdoor access to the system. After Janssen notified IBM of the issue, the latter remediated the issue and started its investigation into whether any unauthorised access to the CarePath system occurred. Recent data breaches in the pharmaceutical sector include a ransomware attack on Eisai in June, due to which several of the company’s systems had to be taken offline. Eisai and Biogen’s antibody therapy, Leqembi (lecanemab-irmb), for Alzheimer’s was approved by the US Food and Drug Administration in January.
