MOVANTIK™ (naloxegol)

  • Internally discovered by Nektar
  • Approved in U.S. for treatment of OIC in adult patients with chronic non-cancer pain
  • Filed in EU and Canada

    MOVANTIK is the first, oral peripherally-acting mu-opioid receptor antagonist (PAMORA) specifically designed for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain. In the Phase 3 clinical studies, MOVANTIK was administered as a once-daily tablet and is designed to block the binding of opioids to the opioid receptors in the gastrointestinal (GI) tract. MOVANTIK was designed using Nektar's proprietary oral, small molecule polymer conjugate technology.
  • NKTR-119 (Movantik fixed-dose combination product)

  • Invented by Nektar
  • Currently in research/preclinical

    NKTR-119 is an investigational drug candidate that is a co-formulation of Movantik (naloxegol) and an opioid analgesic. The product is in preclinical stages for the treatment of pain without the gastrointestinal side effects associated with traditional opioid therapies.
  • NKTR-181

  • Etirinotecan pegol (NKTR-102)

  • Internally discovered by Nektar
  • Currently in Phase 3 clinical trials in metastatic breast cancer
  • Long-acting topoisomerase I-inhibitor

    Etirinotecan pegol (NKTR-102) is the first long-acting topoisomerase I-inhibitor designed to concentrate in tumor tissue, provide sustained tumor suppression throughout the entire chemotherapy cycle, and to reduce the peak exposures that are associated with toxicities of other cytotoxics.

    ADYNOVATE™ [Antihemophilic Factor (Recombinant), PEGylated]
    • ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated], an extended circulating half-life recombinant Factor VIII (rFVIII) treatment for hemophilia A. ADYNOVATE is built on the full-length ADVATE [Antihemophilic Factor (Recombinant)] molecule, a leading treatment for hemophilia A with more than 12 years of real-world patient experience.
    • Invented by Nektar
    Through a collaboration with Nektar, ADYNOVATE leverages Nektarís proprietary pegylation technology designed to prolong the amount of FVIII available for use in the body. The technology was selected because it maintains the integrity of the parent molecule (ADVATE) and reduces the speed at which the body clears ADYNOVATE, resulting in increased circulating half-life. This proprietary technology has been used for more than 15 years in a number of approved medicines that treat chronic or serious conditions.

    ADYNOVATE, Antihemophilic Factor (Recombinant), PEGylated, is a human antihemophilic factor indicated in adolescent and adult patients (12 years and older) with hemophilia A (congenital factor VIII deficiency) for:
    • On-demand treatment and control of bleeding episodes
    • Routine prophylaxis to reduce the frequency of bleeding episodes

Ophthotech has begun treating patients in two of three Phase 3 clinical trials for Fovista and plans to enroll 1,866 patients in its Phase 3 clinical trials. Two of the three Phase 3 clinical trials will evaluate the efficacy and safety of Fovista® administered in combination with Lucentis®; a third clinical trial will evaluate Fovista® administered in combination with each of Avastin® or Eylea®.

    Nektar has an exclusive worldwide license agreement with Ophthotech for Fovista. As part of the agreement, Nektar is entitled to development and commercial milestones and royalties on product sales of Fovista.
    Revolixys™

    The Revolixys Kit, is a two-component system comprising a Factor IXa inhibitor anticoagulant and its specific active control agent. Revolixys is being developed for use in patients suffering from acute coronary syndrome (ACS), including those who undergo coronary revascularization procedures, which include percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). These procedures put patients at risk for therapy-related bleeding complications. Revolixys is designed to increase therapeutic flexibility while reducing side effects and improving outcomes experienced by patients in this setting.

    The Revolixys Kit, is currently being evaluated in a Phase 3, PROBE design (Prospective, Randomized, Open-label, Blinded-Endpoint) superiority study (REGULATE-PCI) comparing the effects of Revolixys to bivalirudin in patients undergoing percutaneous coronary intervention (PCI) electively or for the treatment of unstable angina (UA) or non-ST elevated myocardial infarction (N-STEMI). REGULATE-PCI, if successful, will serve as the basis for product registration applications throughout the world.

    Nektar has an exclusive worldwide license agreement with Regado for Revolixys. As part of the agreement, Nektar is entitled to development and commercial milestones and royalties on product sales of Revolixys.
    SEMPRANA™ (dihydroergotamine)

    Under the terms of a license agreement between Nektar and Allergan, Inc., Nektar is entitled to receive royalties on the global sales of SEMPRANA for all indications. SEMPRANA is an orally inhaled version of dihydroergotamine (DHE), self-administered via Allergan's proprietary TEMPO® inhaler. DHE is available as an intravenous therapy which has been used in clinical settings for over 50 years to safely treat migraine. A New Drug Application (NDA) for SEMPRANA is currently being reviewed by the U.S. Food and Drug Administration (FDA).
    PEGPH20

    PEGPH20 is an investigational PEGylated form of Halozyme's proprietary recombinant human hyaluronidase under development for the systemic treatment of tumors that accumulate hyaluronan (HA). Emerging data show that most pancreatic cancers surround themselves with a protective hyaluronan-rich matrix, which makes the disease difficult to treat and is an indicator of poor prognosis. PEGPH20 has been shown to deplete this matrix component from the tumor that rapidly changes the tumor microenvironment and metabolism, which may render the tumor more vulnerable to therapy as well as inhibit tumor growth. PEGPH20 is currently being evaluated in a Phase 2 multicenter, randomized clinical trial of nab-paclitaxel and gemcitabine with and without PEGPH20 to assess the combination treatment effect as measured by ORR, PFS and OS. The study is expected to enroll approximately 124 patients with stage IV metastatic pancreatic cancer. A second Phase 2 study will evaluate PEGPH20 in combination with modified FOLFIRINOX in approximately 144 patients with advanced pancreatic cancer.

    Nektar has an exclusive worldwide license agreement with Halozyme for PEGPH20. As part of the agreement, Nektar is entitled to development and commercial milestones and royalties on product sales of PEGPH20.
    Dapirolizumab Pegol (Anti-CD40L)

    Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that occurs when the body's own immune system mistakenly attacks healthy tissue in skin, joints, kidneys, the brain and other organs. It is a difficult disease to diagnose because it resembles several other conditions.

    CD40L is a protein in B and T cells, which helps regulate the immune system. Dapirolizumab pegol (Anti-CD40L) is an antibody that blocks CD40L, potentially lessening disease activity in SLE patients. Dapirolizumab pegol is being developed by Biogen and UCB, Inc.
