ViiV Healthcare and CHAI Collaboration Delivers Second Milestone With First Filing With the FDA of Generic Dolutegravir by Aurobindo Pharma for the Treatment of HIV

London (ots/PRNewswire) - ViiV Healthcare, Aurobindo Pharma, and the Clinton Health Access Initiative, Inc. (CHAI) announced today that Aurobindo Pharma has submitted an Abbreviated New Drug Application (ANDA) for dolutegravir 50mg, for Tentative Approval, to the Food and Drug Administration (FDA), for the treatment of HIV. This is the first ANDA for a generic version of dolutegravir, less than two years after FDA approval of Tivicay(R) (dolutegravir) for sale in the United States.

Upon receiving Tentative Approval from the FDA, Aurobindo Pharma will be able to supply dolutegravir 50mg via the President's Emergency Plan for AIDS Relief (PEPFAR) programme, following completion of required local regulatory approval process, in the licensed countries outside of the United States, as per the agreement signed between Aurobindo Pharma and ViiV Healthcare in 2014.

This submission comes less than five years after ViiV Healthcare and CHAI signed an agreement to collaborate with the goal of bringing innovative formulations of medicines for the treatment and prevention of HIV/AIDS to people living with HIV in developing countries, on an affordable yet sustainable basis.

CHAI and ViiV Healthcare worked together to identify a generic partner after conducting feasibility research. Following this initial joint work, ViiV Healthcare submitted necessary documentation to the FDA providing a selective waiver letter for the five-year period of New Chemical Entity (NCE) exclusivity that would have otherwise prevented FDA review and Tentative Approval of Aurobindo Pharma's ANDA at this time.

Dr. Dominique Limet, CEO, ViiV Healthcare, said: "This first ANDA for a generic dolutegravir confirms that our strong commitment to thinking and acting differently to pursue new ways to expand access to our medicines, for people living with HIV in countries where the need is most pressing, is working."

David Ripin, PhD, Executive Vice President, and Chief Scientific Officer, CHAI, said: "UNAIDS has set global public health goals calling for 90 percent of those who are HIV-positive to know their status, 90 percent of those identified to be linked to treatment programs, and 90 percent of those in treatment to achieve undetectable viral load. To tackle these complex challenges, targeted efforts to facilitate access to HIV treatment medicines, such as dolutegravir, are needed."

Mr. N. Govindarajan, Managing Director, Aurobindo Pharma, said: "We are pleased to be part of this innovative partnership designed to accelerate access to medicines for treating HIV. Aurobindo Pharma is committed to HIV care and aims to achieve the goals of wider access to HIV treatment, care, and support; seeking to address the spread of HIV through development of this newer class of drugs and fixed-dose combinations for low- and middle-income countries."

The filing by Aurobindo Pharma is the second result of the agreement between CHAI and ViiV Healthcare and comes less than six months after another generic manufacturer announced that it had received Tentative Approval from the FDA for paediatric formulations of another ViiV Healthcare antiretroviral (also under PEPFAR for sale in licensed countries outside of the United States), through innovative collaboration with ViiV Healthcare and CHAI.

About Clinton Health Access Initiative

The Clinton Health Access Initiative, Inc. (CHAI) was founded in 2002 with a transformational goal: help save the lives of millions of people living with HIV/AIDS in the developing world by dramatically scaling up antiretroviral treatment. When CHAI was founded, many viewed this goal as unreasonable because health systems in poor countries were too weak and prices of relevant drugs and diagnostic tests were too high. CHAI played a leadership role, working alongside governments and other partners, to lower the costs of treatment and help build the in-country systems necessary to provide lifesaving treatment to millions of people. Since then, CHAI has pursued several similarly ambitious goals, from scaling up pediatric AIDS treatment in order to achieve equity with adults in a timeframe few thought possible, to rapidly accelerating the rollout of new vaccines. CHAI has achieved many of its most important successes when seeking to fundamentally change the way the world approaches an issue and pushing the boundaries of what is considered feasible in global health.

About President's Emergency Plan for AIDS Relief (PEPFAR)

PEPFAR is the US government initiative to help save the lives of those suffering from HIV/AIDS around the world. This historic commitment is the largest by any nation to combat a single disease internationally. In May 2004, in support of the President's Emergency Plan, the FDA announced a new initiative to help ensure that those being served by the President's Plan would receive safe, effective, and quality manufactured antiretroviral drugs. This new initiative included an expedited review process. Through guidance and an active outreach program to the pharmaceutical industry, the FDA actively encouraged any sponsors worldwide to submit US marketing applications for single entity, fixed dose combination (FDC), and co-packaged versions of previously approved antiretroviral therapies-even if there was still patent or exclusivity market protection for the product in the US.

Important Information about Tivicay(R) (dolutegravir) in the US

FDA Indication and Usage: TIVICAY is a human immunodeficiency virus type 1 (HIV-1) integrase strand transfer inhibitor (INSTI) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection.

Use of TIVICAY in INSTI-experienced patients should be guided by the number and type of baseline INSTI substitutions. The efficacy of TIVICAY 50 mg twice daily is reduced in patients with an INSTI-resistance Q148 substitution plus 2 or more additional INSTI-resistance substitutions including T66A, L74I/M, E138A/K/T, G140S/A/C, Y143R/C/H, E157Q, G163S/E/K/Q, or G193E/R.

Important Safety Information for Tivicay(R) (dolutegravir)

Contraindication: TIVICAY is contraindicated (1) in patients with previous hypersensitivity reaction to dolutegravir, and (2) in patients receiving dofetilide (antiarrhythmic) due to the potential for increased dofetilide plasma concentrations and the risk for serious and/or life-threatening events.

Hypersensitivity Reactions: Hypersensitivity reactions have been reported and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. The events were reported in 1% or fewer subjects receiving TIVICAY in Phase 3 clinical trials. Discontinue TIVICAY and other suspect agents immediately if signs or symptoms of hypersensitivity reaction develop, (including but not limited to, severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters or peeling of the skin, oral blisters or lesions, conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema, difficulty breathing.) Monitor clinical status, including liver aminotransferases, and initiate appropriate therapy. Delay in stopping treatment with TIVICAY or other suspect agents after the onset of hypersensitivity may result in a life-threatening reaction. TIVICAY is contraindicated in patients who have experienced a hypersensitivity reaction to dolutegravir.

Effects on Serum Liver Biochemistries in Patients with Hepatitis B or C Coinfection: Patients with underlying hepatitis B or C may be at increased risk for worsening or development of transaminase elevations with use of TIVICAY. In some cases the elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation particularly in the setting where anti-hepatitis therapy was withdrawn. Appropriate laboratory testing prior to initiating therapy and monitoring for hepatotoxicity during therapy with TIVICAY are recommended in patients with underlying hepatic disease such as hepatitis B or C.

Fat Redistribution: Redistribution/accumulation of body fat has been observed in patients receiving antiretroviral therapy.

Immune Reconstitution Syndrome: During the initial phase of treatment, immune reconstitution syndrome can occur, which may necessitate further evaluation and treatment. Autoimmune disorders have been reported to occur in the setting of immune reconstitution; the time to onset is more variable and can occur many months after initiation of treatment.

Adverse Reactions: The most commonly reported (greater than or equal to2%) adverse reactions of moderate to severe intensity in treatment naive adult subjects in any one trial receiving TIVICAY in a combination regimen were insomnia (3%), fatigue (2%), and headache (2%).

Drug Interactions: Co-administration of TIVICAY with drugs that are strong inducers of UGT1A1 and/or CYP3A4 may result in reduced plasma concentrations of dolutegravir and require dose adjustments of TIVICAY.

- TIVICAY should be taken2 hours before or 6 hours after taking cation-containing antacids or laxatives, sucralfate, oral iron supplements, oral calcium supplements, or buffered medications.

- Consult the full Prescribing Information for TIVICAY for more information on potentially significant drug interactions, including clinical comments.

Pregnancy: Pregnancy category B. TIVICAY should be used during pregnancy only if the potential benefit justifies the potential risk. An Antiretroviral Pregnancy Registry has been established.

Breastfeeding: Breastfeeding is NOT recommended due to the potential for HIV transmission and the potential for adverse reactions in nursing infants.

Paediatric Patients: Safety and efficacy of TIVICAY has not been established in children younger than 12 years old, or weighing <40 kg, or in INSTI-experienced paediatric patients with documented or clinically suspected INSTI resistance.

How Tivicay Works Tivicay belongs to a class of HIV medicines called integrase inhibitors. Integrase inhibitors block 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 infection.

Tivicay is a registered trademark of the ViiV Healthcare group of companies.
