Axsome Therapeutics Announces FDA Acceptance of NDA Resubmission for AXS-07 for the Acute Treatment of Migraine

Today’s cyclodextrin update brings news of the 2nd oral drug to be marketed using sulfobutylether-beta-CD.

Axsome Therapeutics, Inc. has announced that the U.S. FDA has acknowledged the resubmission of the NDA for AXS-07, an oral, rapidly absorbed, multi-mechanistic investigational medicine for the acute treatment of migraine. AXS-07 combines MoSEIC™ meloxicam and rizatriptan, offering a new molecular entity for migraine treatment enabled by Axsome’s innovative technology.

About Migraine
Migraine is a serious neurological condition characterized by recurrent attacks of pulsating, often severe and disabling head pain associated with nausea, sensitivity to light, and sensitivity to sound. An estimated 39 million Americans suffer from migraine, and it is the leading cause of disability among neurological disorders in the United States according to the American Migraine Foundation. Published surveys of migraine sufferers found that more than 70% are not fully satisfied with their current treatment and desire therapies that work faster, more consistently, and result in less symptom recurrence.

About AXS-07
AXS-07 is a novel, oral, rapidly absorbed, multi-mechanistic investigational medicine for the acute treatment of migraine, consisting of MoSEIC™ meloxicam and rizatriptan. Meloxicam is a new molecular entity for migraine enabled by Axsome’s MoSEIC (Molecular Solubility Enhanced Inclusion Complex) technology, which results in rapid absorption of meloxicam while maintaining a long plasma half-life. Meloxicam is a COX-2 preferential non-steroidal anti-inflammatory drug and rizatriptan is a 5-HT1B/1D agonist. AXS-07 is designed to provide rapid, enhanced and consistent relief of migraine, with reduced symptom recurrence. AXS-07 is covered by more than 200 issued U.S. and international patents which provide protection until at least 2038. AXS-07 is not approved by the FDA.

Role of Cyclodextrin Cross-Linker Type on Steroid Hormone Micropollutant Removal from Water Using Composite Nanofiber Membrane

Today’s cyclodextrin is about water purification.

What if we could make our water cleaner using a safer, composite nanofiber membrane?

This study investigates how different cross-linkers affect the stability and micropollutant removal efficiency of β-cyclodextrin polymers in composite nanofiber membranes. It finds that triphenylolmethane triglycidyl ether (TPTE) and trimethylolpropane triglycidyl ether (TMTE) are effective alternatives to the more toxic epichlorohydrin (EP) for removing steroid hormones from water.

AI-driven cyclodextrin drug design

Fascinating research by Amelia Anderson & Matthew “Oki” O’Connor from Cyclarity Therapeutics and Angel Piñeiro & Rebeca Garcia-Fandino from Universidad de Santiago de Compostela

Computational methods represent an exceptional complement to in vitro assays because they can be employed for existing and hypothetical molecules, providing high resolution structures in addition to a mechanistic, dynamic, kinetic, and thermodynamic characterization.

Bridging computational methods with complex molecular interactions, this research enables predictive CD designs for diverse applications. Moreover, the high reproducibility, sensitivity, and cost-effectiveness of the studied methods pave the way for extensive studies of massive CD-ligand combinations, enabling AI algorithm training and automated molecular design.

Preparation of Carvacrol β-Cyclodextrin Inclusions and 1-Methylcyclopropene-α-CD Coated Paper by Water-Free Method for Postharvest Preservation of Peach

Today’s cyclodextrin: is a packaging/food preservation application

Where Carvacrol β-Cyclodextrin Inclusions and 1-Methylcyclopropene-α-CD Coated Paper are for post-harvest preservation of peach.

Carvacrol essential oil has broad-spectrum antibacterial properties, but it is volatile and unstable for long-term storage and use. In the present study, carvacrol was encapsulated with β-cyclodextrin to improve its relevant properties.

PEG was used to form the film in the anhydrous condition, and the compound and ethylene inhibitor 1-methylcyclopropene (1-MCP) were included to obtain the film-coated paper.

This study provides a solution for preparing controlled-release coated paper with essential oils and 1-MCP bioactives to extend the shelf life of fruits and vegetables.

The Gut and Skin Microbiome and Its Association with Aging Clocks

Do you know what the aging clock is?

In the paper of Mildred Min, Caitlin Egli and Raja Sivamani M.D., M.S., A.P. you can learn about these predictive models of biological age derived from age-related changes, such as epigenetic changes, blood biomarkers, and, more recently, the microbiome.

Recent studies have shown that human microbiomes may predict aging.

In this narrative review, they discuss how the gut and skin microbiomes influence aging clocks as well as clarify the distinction between chronological and biological age.

Reusable Cyclodextrin-Mediated Electrochemical Sensor in Automated Flow Cell for Cortisol Detection

Today’s cyclodextrin is detecting cortisol.

It comes from the oven of Ferdows Sajedi and Jeffrey Halpern at University of New Hampshire. The focus is on using beta-cyclodextrin (βCD) to electrochemically detect cortisol employing an automated flow cell system.

The ultimate goal is to optimize sensor stability, sensitivity, and reproducibility, contributing to the advancement of cortisol detection with the automated cyclodextrin-mediated biosensors.

Oculis closes Phase 3 eye drop trial due to ‘administrative error’ from third party

Today’s cyclodextrin is some news fresh from Oculis‘s oven about the lead drug OCS-01, which is delivered with a unique and proprietary cyclodextrin technology.

The company reported in its second-quarter financial filing that a Phase 3 trial for Oculis’ lead eye drop candidate will be shut down due to an administrative error.

The company added, however, that it had a pre-NDA meeting with the FDA this month, where it got the go-ahead to still file for approval in the first quarter of next year. According to Oculis, the agency confirmed the data it already has from its first Phase 3 trial and a Phase 2 trial, alongside safety data from other studies in ocular surgery and diabetic macular edema, are enough to support an NDA submission.

I’m so happy that this unfortunate event does not seem to hold back the progress of this amazing drug and technology.

If OCS-01 is approved, it would be the first daily and preservative-free steroid for treating inflammation and pain following ocular surgery.

Risperidone-cyclodextrin complex reservoir combined with hydrogel-forming microneedle array patches for enhanced transdermal delivery

Today’s cyclodextrin is about one of favourite novel DDS: microneedles!

Hydrogel-forming microneedle array patches (HFMAPs) are microneedles that create microconduits upon insertion and swelling in the skin, potentially allowing prolonged drug delivery without generating sharps waste.

To enhance the aqueous solubility and successfully deliver risperidone hydroxypropyl-beta-cyclodextrin (HP-β-CD) and hydroxypropyl-gamma-cyclodextrin (HP-γ-CD) were utilized and their performance was tested using phase solubility studies.

For a 1-day application, HFMAPs showed greater systemic exposure to RIS compared to intramuscular control and exposure was extended to 5 days.

In conclusion, HFMAPs could serve as an alternative for delivering RIS in a sustained manner, potentially improving the treatment of schizophrenia.

Supersaturated Drug Delivery System of Oxyberberine Based on Cyclodextrin Nanoaggregates: Preparation, Characterization, and in vivo Application

Today’s cyclodextrin is a fascinating practical application of CDs – how can we create a supersatured drug delivery system (SDDS)?

In this paper, Oxyberberine (OBB) – hydroxypropyl-β-CD SDDS was prepared using the ultrasonic-solvent evaporation method.

The oral relative bioavailability of OBB-HP-β-CD SDDS was also 16 times enhanced compared to that of the raw material. Finally, an in vivo pharmacodynamic assay showed that the anti-hyperuricemic potency of OBB-HP-β-CD SDDS was approximately 5– 10 times higher than that of OBB raw material.

Hydroxypropyl-β-cyclodextrin for the consolidation of vegetable-tanned leather artifacts

The fragility and weakness of historical, archaeological, and heritage leather artifacts in museums, and libraries due to unsuitable environmental conditions are significant challenges.

Vegetable-tanned leather samples were treated with different concentrations of Hydroxypropyl Beta Cyclodextrin and subjected to artificial heat aging.

Results showed that Hydroxypropyl Beta Cyclodextrin at 1% and 2% concentrations improved chemical stability, surface morphology, color retention, and mechanical properties of the leather samples.
