Cabotegravir sodium

Approved for pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV infection in at-risk adults and adolescents aged 12 years and older, weighing at least 35 kg, including men who have sex with men, transgender women, and cisgender women. APRETUDE (cabotegravir extended release injectable suspension) is the first and only long-acting injectable PrEP treatment approved in Canada. Given as few as six times per year after initiation and demonstrated superior efficacy to a daily oral PrEP option (FTC/TDF tablets) in reducing the risk of HIV acquisition in 2 clinical trials.1 The latest Canadian surveillance data shows that there were 1,833 new HIV diagnoses in 2022, a 24.9 per cent increase from 2021.2 MONTRÉAL, May 13, 2024 /CNW/ - ViiV Healthcare, the global specialist HIV company majority owned by GlaxoSmithKline plc (GSK), with Pfizer Inc. and Shionogi as shareholders, announced that Health Canada has granted approval for APRETUDE (cabotegravir tablets and extended release injectable suspension) for pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 infection in at risk individuals who are HIV-1 negative.1 APRETUDE is indicated for at-risk adults and adolescents aged 12 years and older and weighing at least 35 kg for PrEP to reduce the risk of sexually acquired HIV-1 infection.1 APRETUDE is the only long-acting injectable HIV PrEP option approved in Canada that reduces the number of doses needed for effective HIV prevention from daily pills to as few as six injections per year. Cabotegravir tablets and extended release injectable suspension for PrEP has demonstrated superior efficacy to daily oral emtricitabine/tenofovir disoproxil fumarate (FTC/TDF tablets) in reducing the risk of HIV acquisition in 2 clinical trials, giving Canadians more options for PrEP.1 Jean-Francois Fortin, Country Medical Director, Canada at ViiV Healthcare, said: "With the approval of APRETUDE in Canada, we are proud to be able to offer a new prevention option for Canadians at risk of acquiring HIV. We are confident that by providing another highly effective preventative option for Canadians, we are one step closer to our collective goal of ending the HIV epidemic. We look forward to working with provincial, territorial, and national health authorities to bring APRETUDE to Canadians across the country." HIV remains a critical public health issue in Canada, with cases of HIV increasing by 24.9 per cent in 2022 from 2021.2 PrEP has been identified as an effective tool in reducing new cases of HIV, key to ending the HIV epidemic. Despite the wide availability of daily oral PrEP, inconsistent adherence as well as structural and cultural barriers lead to underutilization in key populations. Health Canada approval was based on the results of two key phase IIb/III studies, HPTN 083 and HPTN 084, which evaluated the safety and efficacy of cabotegravir long-acting for PrEP in men who have sex with men, transgender women, and cisgender women who were at increased risk of HIV.3,4 The studies demonstrated that cabotegravir long-acting injectables for PrEP was superior to daily oral emtricitabine/tenofovir disproxil fumarate (FTC/TDF), with clinical trial participants experiencing 69 per cent lower rate of HIV acquisition compared to FTC/TDF tablets in HPTN 083, and a 90 per cent lower rate of HIV acquisition compared to FTC/TDF tablets in HPTN 084.5,6 About Cabotegravir extended release injectable suspension Cabotegravir extended release injectable suspension is the first and only long-acting injectable pre-exposure prophylaxis (PrEP) option proven superior to daily oral FTC/TDF in reducing HIV acquisition. It is indicated for at-risk adults and adolescents aged 12 years and older, weighing at least 35 kg for PrEP to reduce the risk of sexually acquired HIV-1 infection. Cabotegravir extended release injectable suspension is administered as a single 600 mg (3-ml) intramuscular (IM) injection of cabotegravir in the buttocks by a health care professional every two months after two initiation injections administered one month apart. Cabotegravir tablets can be used as an optional oral lead-in to assess tolerability or as short-term oral PrEP in individuals who will miss planned dosing with cabotegravir extended release injectable suspension. Cabotegravir is an integrase strand transfer inhibitor (INSTI). INSTIs, like cabotegravir extended release injectable suspension, inhibit HIV replication by preventing the viral DNA from integrating into the genetic material of human immune cells (T-cells). This step is essential in the HIV replication cycle and is also responsible for establishing chronic disease.1 About HPTN 083 (NCT02720094)7 The HPTN 083 trial is a phase IIb/III double blind non-inferiority trial designed to evaluate the safety and efficacy of long-acting injectable cabotegravir for HIV prevention administered every eight weeks compared to daily oral FTC/TDF tablets (200 mg/300 mg). The trial included the prespecified ability to test for superiority of long-acting cabotegravir over FTC/TDF. The trial design included an oral lead-in phase to assess tolerability to cabotegravir before administering the intramuscular injection. HPTN 083 was conducted in 4,566 men who have sex with men and transgender women who have sex with men. The study opened to enrollment in November 2016 at research centres in Argentina, Brazil, Peru, United States, South Africa, and Vietnam.5 At a pre-planned interim review of trial data, a multinational Data and Safety Monitoring Board (MDSMB) recommended that the blinded phase of HPTN 083 be stopped due to the demonstration of superior efficacy of cabotegravir when compared to daily, oral FTC/TDF and that subjects randomized to the active FTC/TDF group be offered cabotegravir. The most common adverse reactions (all grades) observed in at least 1 per cent of subjects receiving long acting cabotegravir were injection sites reactions, diarrhea, headache, pyrexia, fatigue, sleep disorders, nausea, dizziness, flatulence, and abdominal pain.5 For further information on HPTN 083 please see . About HPTN 084 (NCT03164564)6 The HPTN 084 trial is a phase III double blind superiority trial designed to evaluate the safety and efficacy of the long-acting injectable cabotegravir for HIV prevention administered every eight weeks compared to daily oral FTC/TDF tablets (200 mg/300 mg) in 3,224 cisgender women who are at increased risk of HIV acquisition. The trial design included an oral lead-in phase to assess tolerability to cabotegravir before administering the intramuscular injection. HPTN 084 opened to enrolment in November 2017 and is being conducted at research centres in Botswana, Kenya, Malawi, South Africa, Eswatini, Uganda, and Zimbabwe.6 The MDSMB recommended early termination of the blinded, randomized portion of HPTN 084 after an interim analysis indicated that pre-specified stopping criteria had been met (superiority of cabotegravir compared with FTC/TDF). The most common adverse reactions (all grades) observed in at least 1% of subjects receiving long acting cabotegravir were injection site reactions, diarrhea, headache, fatigue, sleep disorders, nausea, dizziness, abdominal pain, vomiting, myalgia, and rash.6 For further information please see . About HIV HIV (human immunodeficiency virus) is a virus that attacks the body's immune system.8 HIV is spread by contact with certain bodily fluids of a person with HIV, most commonly during unprotected sex (sex without a condom or HIV medicine to prevent or treat HIV), or through sharing injected drug equipment.9 If HIV is not treated, it can lead to AIDS (acquired immunodeficiency virus). AIDS is the most severe stage of HIV (Stage 3).10 There is currently no cure for HIV, but with proper treatment and care, people with HIV can maintain a high quality of life and avoid passing HIV to others. At the end of 2022, 39 million people lived with HIV around the world, with 1.3 million new diagnoses that year and 630,000 deaths from AIDS-related illnesses.11 Important Safety Information for APRETUDE for PrEP1 The APRETUDE Product Monograph includes a Serious Warning and Precautions Box: RISK OF DRUG RESISTANCE WITH USE OF APRETUDE IN UNDIAGNOSED HIV-1 INFECTION.1 Individuals must be tested for HIV-1 infection prior to initiating APRETUDE and should be tested for HIV-1 infection with each subsequent injection of APRETUDE. APRETUDE must not be prescribed until confirmation of negative HIV-1 infection status. Drug-resistant HIV-1 variants have been identified with use of APRETUDE by individuals with undiagnosed HIV-1 infection. Do not initiate APRETUDE if signs or symptoms of acute HIV-1 infection are present unless negative infection status is confirmed.1 Individuals who become infected with HIV-1 while receiving APRETUDE must transition to a complete HIV-1 treatment regimen.

Aspaveli, known as Empaveli in the US, is approved there for the treatment of adults with PNH. Credit: swiftsciencewriting from Pixabay. Sobi has received approval for an indication extension from the European Commission for Aspaveli to treat adults with paroxysmal nocturnal haemoglobinuria (PNH) who have haemolytic anaemia. Uncontrolled complement activation in PNH, a chronic and life-threatening blood disorder, leads to the destruction of red blood cells that carry oxygen. Aspaveli is approved in Europe to treat adult PNH patients who are anaemic following treatment with a C5 inhibitor for at least three months. It is now the first C3 inhibitor approved for first-line PNH treatment in Europe, potentially improving patient outcomes by addressing haemoglobin levels and other clinical markers. The approval for Aspaveli’s extended indication is based on data from the APL2-308 (PRINCE) study, an open-label, randomised, comparator-controlled trial. See Also: TerSera’s ZOLADEX LA gains Health Canada approval for breast cancer UK MHRA approves ViiV Healthcare’s cabotegravir formulations for HIV-1 The study included patients who had not received any complement inhibitor treatment within three months before enrolment and exhibited haemoglobin levels below the normal lower limit and lactate dehydrogenase levels at least 1.5 times above the normal upper limit. Over 26 weeks, the efficacy and safety of Aspaveli were assessed against standard care, which includes treatments such as transfusions and corticosteroids but excludes complement inhibitors. Sobi chief medical officer and research and development and medical affairs head Lydia Abad-Franch stated: “Today’s approval underscores the robust clinical data supporting Aspaveli ‘s efficacy and safety profile, offering healthcare professionals and patients an expanded toolkit for effectively managing PNH. “European patients will now be able to initiate treatment with Aspaveli at diagnosis or switch from their current C5 inhibitor treatment if they present indicators of haemolytic anaemia.” Aspaveli, known as Empaveli in the US and commercialised by Apellis, is also approved there for the treatment of adults with PNH. It is under investigation for the potential treatment of other rare diseases across the haematology and nephrology sectors.
