Background: The phase 2 ASUNCTIS study assessed the efficacy and safety of asunercept, a fully human CD95 (Fas) ligand-binding protein, in hospitalised patients with moderate-to-severe coronavirus disease (COVID-19) to assess the clinical benefit of CD95 ligand inhibition in this viral disease.

Methods: In this open-label, multicentre, randomised, controlled, phase 2 trial, patients with COVID-19-induced pneumonia and respiratory deterioration were randomly assigned (1:1:1:1) in 12 Russian and Spanish hospitals using an interactive web-response system to receive standard of care (SOC) or SOC plus weekly asunercept 25 mg, 100 mg, or 400 mg, administered intravenously for up to 4 weeks, or until hospital discharge or death. The randomisation was stratified according to the respiratory support methods at the time of enrolment, corresponding to categories 4-6 of a clinical severity assessment scale comprising 9 levels that was recommended by the World Health Organization (WHO) at the time of the study.

Article Synopsis
  • The study focused on the occurrence of febrile neutropenia (FN) in patients with intermediate risk while undergoing chemotherapy, aiming to better understand its incidence.
  • The research involved 364 patients with solid tumors or lymphomas, tracking them through multiple cycles of chemotherapy; FN rates were highest during the first cycle.
  • Findings indicated a low overall FN incidence, especially after the first cycle, suggesting that, based on clinician discretion, prophylactic use of granulocyte colony-stimulating factor (G-CSF) might be beneficial for these patients.

Innovative medicinal products are required for progress in many therapeutic areas, and in particular, oncology. For these products to succeed, pharmaceutical companies must generate the relevant and robust clinical data required to meet the needs of regulators and healthcare providers. In addition, real-world and health economic evidence is increasingly required to support pricing and reimbursement for innovative medicinal products.

Article Synopsis
  • Even though doctors really support them, there still aren't enough trials for rare cancers that adapt over time.
  • The paper talks about new ways to design these trials and includes information from a survey of over 3,200 doctors about their opinions on different trial methods.
  • Most doctors (97%) believe that adaptive trials are just as valuable as standard ones for treating rare cancers, and they think new approaches can help patients get better treatments faster.

The ability of FasL/CD95L to induce apoptosis in various Fas/CD95-expressing cells has been described in the context of hematopoiesis or thymic elimination of self-reactive T cells and resolution of an acute immune response under physiological conditions. At the same time, non-apoptotic CD95 activation is widely described in cancer and shown to stimulate invasiveness of cancer cells, promote cancer progression as well as stemness of cancer cells. This paper puts emphasis on the evolving understanding of expression and the non-apoptotic activities of the CD95/CD95L signaling pathway on the function of tumor cells, tumor microenvironment and immune cells.

The pharmaceutical industry is subject to complex regulations relating to the safety and efficacy of medicinal products, as well as pricing and reimbursement, added value, communication, and advertising. In addition, multiple stakeholders have evolved and now not only include physicians, but also payers, regulatory authorities, patients, and patient advocacy groups in the move toward an added value-based healthcare system. The advent of digitalization has also had a significant influence on how healthcare professionals and decision makers are identified and the most effective and preferred methods of communicating with them.

Innovative medicinal products are required to achieve progress in oncology; however, these are associated with high financial investments, extensive development times, and significant risk of potential failure in the pivotal clinical trials required for marketing authorization. With increasing budgetary constraints and requirements to demonstrate value, effective strategies to develop and commercialize innovative oncology products are more important than ever. Strategies that have proved successful in other industries require major revision for use in the oncology field, both during preclinical and clinical development as well as in the post approval value chain.

Glioblastoma is the most common and aggressive malignant tumor of the central nervous system. Despite the existing high unmet medical needs, the past few decades have seen no notable improvement in overall survival for glioblastoma patients. One active area of research to develop new therapeutic options for this disease is focusing on the CD95/Fas receptor and its ligand CD95L/FasL.

Biosimilar filgrastim (Sandoz) was approved in Europe in 2009 and, in 2015, was the first biosimilar approved in the USA. These authorizations were based on the "totality of evidence" concept, an approach that considers data from structural and functional characterization and comparability analysis and non-clinical and clinical studies. For biosimilar filgrastim, phase III confirmatory clinical studies were performed in the most sensitive population, patients with breast cancer undergoing myelosuppressive chemotherapy.

Guidelines recommend febrile neutropenia (FN) prophylaxis following myelotoxic chemotherapy with either daily injections of filgrastim (Neupogen) or biosimilar filgrastim-sndz (Zarzio/Zarxio), single-injection pegfilgrastim (Neulasta), or pegfilgrastim administered through an on-body injector (PEG-OBI; Neulasta Onpro). PEG-OBI failure rates up to 6.9% have been reported, putting patients at incremental risk for FN and FN-related hospitalization.

Myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis, leading to hematopoietic precursor cell apoptosis and peripheral blood cytopenias. Anemia is the most frequently experienced cytopenia and is the main cause of MDS symptoms, with fatigue and dyspnea contributing to reduced quality of life and increased morbidity. As MDS disease course and prognosis is influenced by disease factors, prognostic scoring systems have been developed for MDS to aid clinical and therapeutic decisions following diagnosis.

The recombinant G-CSF filgrastim was first approved in 1991, and its value has been evolving ever since. Initial health technology assessments suggested low value due to high drug cost and no evidence for significant gain in overall survival. However, more recent meta-analyses of placebo-controlled randomized trial data show falling costs due to biosimilar competition and absolute overall survival gains of 3.
