Inhalation of SP-101 Followed by Inhaled Doxorubicin Results in Robust and Durable Transgene Expression in the Airways of Wild-Type and Cystic Fibrosis Ferrets.

Cystic fibrosis (CF) is a serious genetic disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Approved small molecule therapies benefit the majority of people with CF (pwCF), but unfortunately not all. Gene addition offers a mutation agnostic treatment option for all pwCF.

A novel C2 domain binding CD33xCD3 bispecific antibody with potent T-cell redirection activity against acute myeloid leukemia.

CD33 is expressed in 90% of patients with acute myeloid leukemia (AML), and its extracellular portion consists of a V domain and a C2 domain. A recent study showed that a single nucleotide polymorphism (SNP), rs12459419 (C > T), results in the reduced expression of V domain-containing CD33 and limited efficacy of V domain-binding anti-CD33 antibodies. We developed JNJ-67571244, a novel human bispecific antibody capable of binding to the C2 domain of CD33 and to CD3, to induce T-cell recruitment and CD33+ tumor cell cytotoxicity independently of their SNP genotype status.

An IQ Consortium Perspective on The Scientific Committee on Health, Environmental and Emerging Risks Final Opinion on the Need for Nonhuman Primates in Biomedical Research, Production and Testing of Products and Devices (Update 2017).

The recent Scientific Committee on Health, Environmental and Emerging Risks Final Opinion on "The need for nonhuman primates in biomedical research, production and testing of products and devices" (2017 SCHEER) highlights approaches that could significantly contribute to the replacement, reduction, and refinement of nonhuman primate (NHP) studies. Initiatives that have the potential to affect NHP welfare and/or their use are expected to be appropriate, fair, and objective and publicly disseminated information focused on NHPs in biomedical research, which includes toxicologic and pathologic research and testing, should be objectively evaluated by stakeholder scientists, researchers, and veterinarians. Thus, IQ Consortium member companies convened to develop an informed and objective response, focusing on identifying areas of agreement, potential gaps, or missing information in 2017 SCHEER.

Regulatory Forum Opinion Piece: Use and Utility of Animal Models of Disease for Nonclinical Safety Assessment: A Pharmaceutical Industry Survey.

An Innovation and Quality (IQ) Consortium focus group conducted a cross-company survey to evaluate current practices and perceptions around the use of animal models of disease (AMDs) in nonclinical safety assessment of molecules in clinical development. The IQ Consortium group is an organization of pharmaceutical and biotechnology companies with the mission of advancing science and technology. The survey queried the utilization of AMDs during drug discovery in which drug candidates are evaluated in efficacy models and limited short-duration non-Good Laboratory Practices (GLP) toxicology testing and during drug development in which drug candidates are evaluated in GLP toxicology studies.

Changes in aorta alpha1-adrenoceptor number and affinity during one year of streptozotocin-induced diabetes in rats.

alpha(1)-Adrenoceptor function and density in isolated thoracic aorta were measured during the course of streptozotocin-induced diabetes in rats. Diabetes was induced by a single tail vein injection of streptozotocin (60 mg/kg) and was verified by four measures (blood glucose level, increase in food intake, increase in water intake, and characteristic weight changes). Diabetes produced a significant increase in isolated aorta sensitivity to alpha(1)-adrenoceptor activation, manifested as a significant (p < 0.

Development of a long-acting insulin analog using albumin fusion technology.

The primary therapeutic goal for the treatment of diabetes is maintenance of a long-term, near-normoglycemic condition and prevention of the onset or progression of the complications associated with the disease. Although several analogs of human insulin have been developed, the currently prescribed long-acting insulin analogs do not provide a stable basal glycemia for more than a few hours. Here, we report the development of Albulin, a long-acting insulin analog obtained by direct gene fusion of a single-chain human insulin to human serum albumin.

Toward RNase inhibitors: thermodynamics of 2'-CMP/RNase-A binding in multi-ion buffer.

Certain ribonucleases (RNases), such as eosinophil-derived neurotoxin, are associated with pathological conditions (e.g. asthma and inflammatory bowel disease) and can even be overtly cyto(neuro)toxic.

Indirect modulation of dopamine D2 receptors as potential pharmacotherapy for schizophrenia: III. Retinoids.

Present antipsychotic drugs, whose clinical activity correlates with direct binding to dopamine D2 or other receptors, alleviate some of the symptoms of schizophrenia, but not all and not completely in many patients. In continuation of our overview of potential novel antipsychotic pharmacotherapy that would be based upon indirect modulation of dopamine or other neurotransmitter functioning, we focus in this article on the postulated use of retinoid analogs as novel antipsychotic agents. Several lines of evidence can be viewed as implicating retinoid dysregulation in schizophrenia, either as a causative or contributory factor.

Toward the design of ribonuclease (RNase) inhibitors: ion effects on the thermodynamics of binding of 2'-CMP to RNase A.

Ribonucleases (RNases) possess a variety of biological activities and, under certain conditions, are deleterious. Hence, design of selective inhibitors has been suggested as a strategy for treating RNase-related disorders. In the present study, isothermal titration calorimetry was used to measure ion effects on binding thermodynamics of the RNase A competitive inhibitor 2'-CMP as a representative system.
