Specialty Pipeline Monthly Update Critical updates in an ever changing environment December 2018 New drug information ● Gamifant™ (emapalumab-lzsg): The Food and Drug Administration (FDA) approved Sobi Pharmaceuticals’ Gamifant for treatment of pediatric (newborn and older) and adult patients with primary hemophagocytic lymphohistiocytosis (HLH) who have refractory, recurrent or progressive disease or intolerance with conventional HLH therapy. HLH is rare, occurring in only 80 – 100 people in the United States each year.1 Gamifant is to be administered intravenously over one hour twice per week and continued until hematopoietic stem cell transplantation (HSCT) is performed or unacceptable toxicity occurs. Sobi plans to launch Gamifant in early 2019.2 ● Daurismo™ (glasdegib): The FDA approved Pfizer’s oral Daurismo in combination with intravenous low-dose cytarabine for treatment of newly diagnosed acute myeloid leukemia (AML) in adult patients who are ≥ 75 years old or who have comorbidities that preclude use of intensive induction chemotherapy. Daurismo has an annual wholesale acquisition cost (WAC) of $203,100. ● Vitrakvi™ (larotrectinib): The FDA approved Loxo Oncology’s (a development partner of Bayer) tissue agnostic cancer oral medication, Vitrakvi, for treatment of adult and pediatric patients with solid tumors that: → have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, → are metastatic or where surgical resection is likely to result in severe morbidity, and → have no satisfactory alternative treatments or that have progressed following treatment. The average annual wholesale acquisition cost (WAC) for an adult is $393,600. Sensitive and specific tests are needed to reliably detect NTRK gene fusions that are not commonly ordered in practice as Loxo estimates there are only 2,500 – 3,000 U.S. patients that harbor the NTRK gene fusion annually.3 ● Truxima™ (rituximab-abbs): The FDA approved Truxima, Celltrion and Teva’s biosimilar medication for Roche’s Rituxan®, for the treatment of adult patients with CD20-positive, B-cell non-Hodgkin’s lymphoma (NHL) to be used as a single agent or in combination with chemotherapy. This is the first FDA approved Rituxan biosimilar; the FDA is also reviewing Pfizer’s Rituxan biosimilar product, PF-05280586, which may be approved in July 2019. Celltrion and Teva have not disclosed a price or launch date; however; depending on patent litigation, a Rituxan biosimilar may be able to launch in the first half of 2019.

Specialty Pipeline Update: December 2018 Page 2 New drug information (continued) ● Xospata™ (gilteritinib): The FDA approved Astellas Pharmaceuticals’ oral Xospata for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with a FLT3 mutation. This mutation represents 30 – 40% of AML patients.4 The annual WAC is ~ $270,000. ● Firdapse™ (amifampridine): The FDA approved Catalyst Pharmaceuticals’ oral Firdapse for treatment of Lambert-Eaton myasthenic syndrome (LEMS), a rare autoimmune disorder characterized by muscle weakness. There are only 400 known cases in the U.S.5 Catalyst plans to launch Firdapse in the first quarter of 2019 at an annual WAC of $375,000.6, 7 ● Herzuma® (trastuzumab-pkrb): Celltrion and Teva received FDA approval for Herzuma, a biosimilar to Genentech/Roche’s Herceptin® for the indication of HER2-positive breast cancer. Herceptin is also approved for HER2-positive gastric cancer, but Herzuma did not receive this indication. This is the second Herceptin biosimilar approval, Mylan and Biocon’s Ogivri® was approved in December 2017, but has not yet launched. Herceptin is anticipated to lose exclusivity in June 2019; however, launch plans have not been released for either of Ogivri or Herzuma. New indications ● Venclexta® (venetoclax) tablets: The FDA granted accelerated approval to Abbvie’s Venclexta for use in combination with azacitidine or decitabine or low-dose cytarabine for treatment of newly diagnosed acute myeloid leukemia (AML) in adult patients who are ≥ 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy. Venclexta was originally approved for the treatment of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior therapy. ● Novoeight® (recombinant anthemophilic factor): The FDA changed Novo Nordisk’s Novoeight’s indication from “control and prevention of bleeding episodes” to “on-demand treatment and control of bleeding episodes.” ● Tecentriq® (atezolizumab): The FDA expanded Roche’s IV Tecentriq label to include use in combination with the Avastin® (bevacizumab), paclitaxel and carboplatin for the first-line treatment of patients with metastatic non-squamous non-small cell lung cancer (NSCLC) with no EGFR or ALK genomic tumor aberrations. Prior to this approval, Tecentriq was approved for metastatic NSCLC patients who have disease progression during or following platinum-containing chemotherapy; as well as certain patients with locally advanced or metastatic urothelial carcinoma. ● Nplate® (romiplostim): The FDA expanded the indication for Amgen’s Nplate to include pediatric patients one year of age and older with immune thrombocytopenia (ITP) for at least six months who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. Specialty Pipeline Update: December 2018 Page 3 December news ● “The FDA Bone, Reproductive and Urologic Drugs Advisory Committee (BRUDAC) are to review data supporting the Biologics License Application (BLA) for Evenity™ (romosozumab) (Amgen and UCB) for the treatment of osteoporosis in postmenopausal women at high risk for fracture at a meeting on 15 January, 2019.”8 ● “Sage Therapeutics, Inc., a clinical-stage biopharmaceutical company developing novel medicines to treat life-altering central nervous system (CNS) disorders, announced that the FDA has extended the Prescription Drug User Fee Act (PDUFA) date for its Priority Review of the New Drug Application (NDA) for Zulresso™ (brexanolone) injection for the treatment of postpartum depression (PPD). The previously disclosed December 19, 2018 PDUFA goal date has been extended by a period of three months to March 19, 2019.”9 ● “Amarin made waves in September when it announced a topline win in the Reduce-It trial of its purified fish oil product Vascepa®. Full data, presented at the American Heart Association meeting in Chicago, added an impressive benefit on harder cardiovascular endpoints.”10 ● “AbbVie has struck a deal with Pfizer that requires Pfizer not to launch its Humira® biosimilar until November 2023. The date falls after biosimilar launch timelines for several other drug makers that have already made their own patent deals with AbbVie. The Pfizer deal marks the seventh time AbbVie has negotiated agreements with companies that delay the introduction of biosimilars for Humira, the company’s best-selling rheumatoid arthritis medicine.”11 Specialty Pipeline Update: December 2018 Page 4 Specialty new product approvals in the past twelve months Route of Generic name Brand name Manufacturer Indication(s) administration Month approved amifampridine Firdapse™ Catalyst Lambert-Eaton myasthenic Oral November 2018 Pharmaceuticals syndrome (LEMS) emapalumab-lzsg Gamifant™ Novimmune Hemophagocytic Intravenous November 2018 lymphohistiocytosis (HLH) elapegademase-lvlr Revcovi™ Leadiant Adenosine deaminase severe Intramuscular October 2018 Pharmaceuticals combined immune deficiency (ADA-SCID) inotersen Tegsedi™ Ionis Hereditary transthyretin- Subcutaneous October 2018 Pharmaceuticals/ mediated amyloidosis (hATTR) Akcea amikacin liposome inhalation Arikayce™ Insmed Mycobacterium avium complex Inhalation September 2018 suspension (MAC) lung disease antihemophilia factor Jivi™ Bayer Hemophilia A Intravenous September 2018 [recombinant] PEGylated-aucl riluzole Tiglutik™ ITF Pharma Amyotrophic lateral sclerosis Oral September 2018 (ALS) cenegermin-bkbj Oxervate™ Dompe farmaceutici Neurotrophic keratitis Eye drop August 2018 SpA lanadelumab-flyo Takhzyro™ Shire Prevention of hereditary Subcutaneous August 2018 angioedema stiripentol Diacomit™ Biocodex In combination with clobazam Oral August 2018 for Dravet syndrome (specialty status pending pricing and distribution information) migalastat Galafold™ Amicus Fabry disease with an amenable Oral August 2018 Therapeutics GLA variant patisiran Onpattro™ Alnylam Polyneuropathy caused by Intravenous August 2018 hATTR lusutrombopag Mulpleta™ Shionogi Thrombocytopenia in chronic Oral August 2018 liver disease who are scheduled to undergo a procedure immune globulin intravenous, Panzyga® Octapharma Primary humoral IV August 2018 human - ifas immunodeficiency (PI) and chronic immune thrombocytopenia (ITP) cannabidiol Epidiolex® GW Pharmaceuticals Lennox-Gastaut syndrome and Oral July 2018 Dravet syndrome baricitinib Olumiant® Lilly/Incyte Rheumatoid arthritis Oral June 2018 pegvaliase-pqpz Palyniziq™ BioMarin Phenylketonuria Subcutaneous June 2018 avatrombopag Doptelet® Dova Thrombocytopenia
