Scientists at Technical Institute of Physics and Chemistry, Chinese Academy of Sciences have disclosed hypocrellin derivatives acting as photosensitizers for photodynamic therapy reported to be useful for the treatment of cancer, bacterial infections and fungal infections.
Hamlet Biopharma AB has announced the presentation of new preclinical-stage molecules that have originated from its long-term collaboration with Lund University and Linnane Pharma AB with the aim of treating bacterial infections by targeting the disease response of the host rather than the pathogen itself.
SVF Vaccines AB, a portfolio company of Karolinska Development AB, has presented positive results from a preclinical study of its immunotherapy SVF-001 targeting chronic hepatitis B (HBV) and D viruses (HDV).
The multidrug resistance of methicillin-resistant Staphylococcus aureus (MRSA) makes it a global threat to public health, and the current first-line treatment for MRSA, the glycopeptide vancomycin, can have toxic effects on the kidney and ear.
Ena Respiratory Pty Ltd. raised an AU$34 million (US$22.4 million) series B round to advance INNA-051, its nasal spray for symptomatic viral respiratory infections, to phase II trials. New investors in the Melbourne-headquartered company include the Gates Foundation and Flu Lab. Existing investors Brandon Capital, Uniseed and Stoic Venture Capital also participated in the round.
Moderna Inc. stopped its efforts to develop mRNA-1647 as a vaccine for preventing congenital cytomegalovirus infection, the most common infectious cause of birth defects in the U.S. The pivotal and placebo-controlled phase III CMVictory study of mRNA-1647 missed the primary efficacy endpoint, which was preventing the infection in seronegative females ages 16 to 40.
Smartbax GmbH has announced the successful first closing of its €4.7 million (US$5.4 million) pre-series A financing round to support development of its next-generation antibiotics against multidrug-resistant (MDR) bacteria. A second closing of the round remains open to investors.
In vaccine development, one might think that targeting multiple epitopes increases the likelihood of improving outcomes. However, when several immunogens are administered together, the immune system does not always generate antibodies against all of them. Two parallel studies have overcome this challenge by using multiple simultaneous immunogens against HIV, effectively triggering various types of broadly neutralizing antibody (bnAb) precursors in two different preclinical animal models.
Aicuris Anti-Infective Cures AG is preparing to file for U.S. FDA approval after reporting positive phase III results for lead antiviral pritelivir in the healing of refractory herpes simplex virus lesions in immunocompromised patients.
As part of global efforts to develop next-generation antibiotics to overcome the growing problem of bacterial resistance to existing drugs, researchers at the Lanzhou Institute of Husbandry and Pharmaceutical Sciences prepared various derivatives of the dimethylcysteamine form of pleuromutilin, a naturally occurring diterpenoid.
