Alzheimer’s disease (AD) is recognized worldwide for its debilitating symptoms of declining cognitive function and gradual memory loss. What remains less clear is exactly what causes the neurodegenerative disease, and how to treat it. “Alzheimer’s disease is characterized by two key pathologies – beta-amyloid plaques and tau neurofibrillary tangles.” Seung-Yong Yoon, CEO of Adel Inc., told BioWorld. “Adel is looking to develop a tau-targeting drug, considering tau has been more correlated with AD symptom progression, and the industry’s need for tau pipelines.”
South Korean biopharma Aribio Co. Ltd. signed a $770 million deal to sign off exclusive rights to its early Alzheimer’s disease drug, AR-1001 (mirodenafil), in China.

Kazia Therapeutics Ltd. has out-licensed paxalisib as a potential treatment for intractable epilepsy in focal cortical dysplasia type 2 and tuberous sclerosis complex disease in a carve-out deal with Sovargen Co. Ltd. for $20.5 million plus sales royalties.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria.

Pharmaust Ltd.’s monepantel met its primary safety endpoints and showed positive signals of potential efficacy in a phase I trial in patients with motor neuron disease (MND)/amyotrophic lateral sclerosis (ALS).

On March 4, 2024, several groups of scientists discussed the challenges of investigating the effects of HIV in the central nervous system (CNS) at the oral abstract session on neuropathogenesis of HIV held during the 31st Conference on Retroviruses and Opportunistic Infections (CROI), in Denver. A cure for HIV will require eliminating the virus in all its reservoirs, those tissues where HIV remains latent but retains the capacity for reactivation and replication. However, despite antiretroviral therapy (ART), the virus could continue to replicate continuously at a low level in some reservoirs, including the CNS.
With the number of people with dementia in Australia expected to nearly double by 2054, the federal government is funding a new AU$50 million (US$32.76 million) biomedical and med-tech incubator program to develop new therapies, medical devices and digital health technologies to address dementia and cognitive decline.
Korean neurodegenerative disease-focused Aribio Co. Ltd. gained the U.K.’s regulatory clearance to start the phase III Polaris-AD trial on AR-1001 (mirodenafil), an investigative therapy for early Alzheimer’s disease (AD). The U.K.’s Medicines and Healthcare products Regulatory Agency gave notice of acceptance to Seoul, South Korea- and San Diego-based Aribio for the clinical study on Feb. 21 after “confirming a favorable ethical opinion,” Aribio said. AR-1001 is an oral phosphodiesterase-5 inhibitor under development to treat early AD.
