Background: The nucleoside FF-10502-01, structurally similar to but with different biologic effects than gemcitabine, shows promising activity both alone and combined with cisplatin in preclinical gemcitabine-resistant tumor models. We conducted an open-label, single-arm, 3 + 3 first-in-human trial to explore the safety, tolerability, and antitumor activity of FF-10502-01 in patients with solid tumors.

Methods: Patients with inoperable metastatic tumors refractory to standard therapies were enrolled. Escalating intravenous FF-10502-01 doses (8-135 mg/m ) were administered weekly for 3 weeks in 28-day cycles until progressive disease or unacceptable toxicity was observed. Three expansion cohorts were subsequently evaluated.

Results: A phase 2 dose of 90 mg/m was determined after evaluating 40 patients. Dose-limiting toxicities included hypotension and nausea. Phase 2a enrolled patients with cholangiocarcinoma (36), gallbladder cancer (10), and pancreatic/other tumors (20). Common adverse events were grade 1-2 rash, pruritus, fever, and fatigue. Grade 3 or 4 hematologic toxicities were observed at low incidences, including thrombocytopenia (5.1%) and neutropenia (2%). Confirmed partial responses (PRs) occurred in five patients with gemcitabine-refractory tumors, including three with cholangiocarcinoma and one each with gallbladder and urothelial cancer. Median progression-free and overall survival rates in patients with cholangiocarcinoma were 24.7 and 39.1 weeks, respectively. Prolonged progression-free survival in patients with cholangiocarcinoma was associated with BAP1 and PBRM1 mutations.

Conclusion: FF-10502-01 was well tolerated with manageable side effects and limited hematologic toxicity. Durable PRs and disease stabilizations were observed in heavily pretreated biliary tract patients who had received prior gemcitabine. FF-10502-01 is distinct from gemcitabine and may represent an effective therapy.

The Rey Auditory Verbal Learning Test (RAVLT) is a classic test used to assess episodic verbal memory in research and clinical practice. We aimed to adapt the RAVLT materials into Russian, provide performance norms across the adult lifespan for the Russian adaptation, and develop a mobile application for automated RAVLT administration across languages. We created three psycholinguistically matched alternative versions of the RAVLT materials in Russian and incorporated them into a new tablet application.

Idiopathic non-mast cell angioedema: Treatment insights from global experts.

Allergy Asthma Proc

From the Division of Allergy and Immunology, Department of Medicine, University of California San Diego, La Jolla, California and.

Idiopathic non-mast cell angioedema (INMA) is a rare disease typified by recurrent attacks of cutaneous and subcutaneous swelling. Every attack carries the potential for severe morbidity and, in the case of laryngeal involvement, mortality. Whereas therapies approved for hereditary angioedema (HAE) have been used in the care of patients with INMA, little is known with regard to their efficacy for the treatment of this disease.

Standardized quality (SQ) house-dust mite (HDM) sublingual immunotherapy tablets (10,000 Japanese allergy units [JAU], equivalent to 6 SQ-HDM in Europe and the United States) are licensed for the treatment of HDM-induced allergic rhinitis (AR) without age restriction, based on 52-week administration clinical trials. There are no large-scale data on the administration of 10,000 JAU for > 1 year in actual clinical practice. To examine the safety and effectiveness of 10,000 JAU during use for up to 3 years at real-world clinical sites in Japan.

Appraisal of the evidence linking hereditary α-tryptasemia with mast cell disorders, hypermobility and dysautonomia.

Allergy Asthma Proc

From the Division of Allergy and Immunology, Department of Medicine, University of California San Diego, La Jolla, California and.

Since its first description more than a decade ago, our understanding of the clinical impact of hereditary alpha-tryptasemia has continued to evolve. First considered to be a genetic disorder with a subset of patients having a syndromic presentation composed of connective tissue abnormalities, symptoms of autonomic dysfunction, and findings of mast cell activation, we now know that hereditary alpha-tryptasemia is a common genetic trait and modifier of mast cell-mediated reactions. More recent studies have shown some previously held associations with congenital hypermobility and postural orthostatic tachycardia syndrome (POTS) to be lacking, and illuminated previously unappreciated associations with clonal and nonclonal mast cell disorders.
