"We look forward to sharing this meaningful information and data from our key vaccine clinical trials with the international infectious disease community next week at the World Vaccine Congress," said Stanley C. Erck, President and CEO, Novavax, Inc. "Our RSV F and NanoFlu vaccines both have strong potential to have significant impact on global public health. We look forward to continuing the advancement of the NanoFlu program and to completing the RSV Prepare trial and preparing the BLA for this program."

About RSV

RSV is the most common cause of lower respiratory tract infections and the leading viral cause of severe lower respiratory tract disease in infants and young children worldwide, with estimated annual infection and mortality rates of 64 million and 160,000, respectively.1 In the US, RSV is the leading cause of hospitalization of infants.2 Despite the induction of post-infection immunity, repeat infection and lifelong susceptibility to RSV is common.3 Currently, there is no approved RSV vaccine available.

RSV F Vaccine Maternal Immunization Program 

In December 2017, Novavax completed a successful informational analysis of the Phase 3 Prepare(TM) clinical trial of its RSV F Vaccine for infants via maternal immunization. The analysis of data from 1,307 infants in the per-protocol population indicate an observed vaccine efficacy in the range of between 45% and 100%. The Company anticipates that it will reach approximately 4,600 participants, including approximately 3,000 actively vaccinated mothers, in the second quarter of 2018, which will enable an interim efficacy analysis with results reported in early 2019. This program continues to be funded under an $89 million grant from the Bill and Melinda Gates Foundation (BMGF), and has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA).

About Influenza

Influenza is a world-wide infectious disease that causes illness in humans with symptoms ranging from mild to life-threatening or even death. Serious illness occurs not only in susceptible populations such as infants, young children and older adults, but also in the general population largely because of infection by continuously evolving strains of influenza which can evade the existing protective antibodies in humans. An estimated one million deaths each year are attributed to influenza.4 Current estimates for seasonal influenza vaccine growth in the top seven markets (U.S., Japan, France, Germany, Italy, Spain and UK), show a potential increase from approximately $3.2 billion in 2015 to $5.3 billion by 2025.5

Nanoflu Phase 1/2 Clinical Trial

Novavax conducted a randomized, observer-blind, comparator-controlled trial of NanoFlu vaccine (in two trivalent formulations: 45µg or 180µg total HA) against IIV3-HD in 330 healthy adults aged 60 years or older. Immunogenicity was measured by hemagglutination inhibition (HAI) and neutralization antibody responses against a panel of vaccine-homologous, and historically and forward-drifted, influenza virus strains.

About NanoFlu(TM) and Matrix M(TM)

NanoFlu vaccine is a recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine candidate produced by Novavax in its Sf9 insect cell baculovirus system. NanoFlu vaccine uses HA amino acid protein sequences that are substantially the same as the recommended strain HA sequences. NanoFlu vaccine contains Novavax' patented saponin-based Matrix-M adjuvant, which has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes.

About Novavax

Novavax, Inc. (Nasdaq:NVAX) is a clinical-stage biotechnology company committed to delivering novel products to prevent infectious diseases. Our RSV and influenza nanoparticle vaccine candidates are Novavax' most advanced clinical programs and are at the forefront of the Company's efforts to improve global health.

Pressmeddelande 21 januari 2019 Immunicum AB (publ) meddelar att resultaten från den kliniska fas I/II-studien med ilixadencel vid långt framskriden levercancer publicerats i Frontiers in Oncology Immunicum AB (publ; IMMU.ST) meddelar idag att den slutliga analysen av data från den undersökande kliniska studien med ilixadencel hos patienter med långt framskriden levercancer har publicerats i tidskriften, Frontiers in Oncology . Dessa data bekräftar de tidigare meddelade positiva egenskaperna gällande säkerhet och tolerabilitet för ilixadencel, både när det ges som enda behandling och i kombination med första linjens standardbehandling, sorafenib. Dessutom påvisades ökade nivåer av tumörspecifika CD8+ T-celler i cirkulerande blod för en majoritet av de utvärderbara patienterna, vilket indikerar ett systemiskt immunologiskt svar. De fullständiga resultaten ger ytterligare insikter om ilixadencels verkningsmekanism, tecken på klinisk effekt samt viktig information som kommer att vara vägl

Immunicum AB (publ) Announces Publication of Phase I/II Clinical Trial Results of Ilixadencel in Advanced Hepatocellular Carcinoma in Frontiers in Oncology21.1.2019 08:30Pressmeddelande

Press Release 21 January 2019 Immunicum AB (publ) Announces Publication of Phase I/II Clinical Trial Results of Ilixadencel in Advanced Hepatocellular Carcinoma in Frontiers in Oncology Immunicum AB (publ; IMMU.ST) announced today that the final data analysis from the exploratory clinical study of ilixadencel in patients with advanced hepatocellular carcinoma (HCC) has been published in the journal, Frontiers in Oncology . The data confirms previously communicated positive safety and tolerability of ilixadencel when administered both alone and in combination with current first-line standard of care, sorafenib. In addition, the data demonstrate an increased frequency of tumor-specific CD8+ T cells in circulating blood for a majority of evaluable patients, indicating a systemic immune response. The complete results provide further insight on ilixadencel's mode of action, signs of clinical activity and important information that will guide the next stage of clinical development. As commun

Karolinska Development's portfolio company Modus Therapeutics completes enrollment in Phase II study with sevuparin7.1.2019 12:00Pressmeddelande

STOCKHOLM, January 7, 2019. Karolinska Development's portfolio company Modus Therapeutics announces that the patient enrollment has been completed in the Phase II study with sevuparin in patients with sickle cell disease (SCD). The results from the study is expected in mid 2019. Modus Therapeutic's randomized, double blind study contains 140 SCD-patients with Acute Vaso Occlusive Crisis (VOC). It compares intravenously administered sevuparin with placebo. The primary endpoint of the study is the demonstration of a reduced time to resolution of patient's VOC. Clincal sites across Europe and the Middle East took part in the study that was conducted in conjunction with Modus Therapeutics' co development partner Ergomed. SCD has a high unmet medical need as there are currently no approved therapies for VOCs. It is an inherited blood disorder that affects between 90,000 to 100,000 patients in the U.S. and is characterized by severely painful VOCs that lead to organ damage due to a lack of o
