A Phase 2, Multicenter, Randomized, Placebo-Controlled, Double-Blind, Three-arm Parallel-Group, 12-Month Study to Evaluate the Safety and Efficacy of ALS-L1023 Administered in Combination With Ranibizumab in Patients With Wet-AMD

The objective of this phase 2 study is to determine the optimal dose of ALS-L1023 by evaluating the safety and efficacy of ALS-L1023 comparing with placebo when used in combination with Ranibizumab for the treatment of wet age-related macular degeneration(AMD).
The study is designed as multicenter, randomized, placebo-controlled, double-blind, three-arm parallel-group phase 2 study in patients with neovascular age-related macular degeneration.
This study consists of two separate phases: a loading phase and a PRN(pro re nata) phase.
Once the subject provides a written informed consent, subject information including demographics, medical history, and concomitant medications will be collected, and only those who meet the inclusion/exclusion criteria will participate in the study.
All subjects who are enrolled in the study will be randomized into three groups Group A (Ranibizumab 0.5mg & ALS-L1023 600mg) or Group B (Ranibizumab 0.5mg & ALS-L1023 1200mg) or Group C (Ranibizumab & placebo) in a 1:1:1 ratio. Randomization will be stratified by whether or not the subject has PCV(polypoidal choroidal vasculopathy) confirmed at Screening test.
During the 3-month loading phase, all subjects will receive a Ranibizumab 0.5mg injection into the vitreous every month and take either the placebo or ALS-L1023 orally twice a day. During the following 3-12 month PRN phase, subjects will continue to take the placebo or ALS-L1023 in the same frequency as above but receive Ranibizumab injection only when it meets retreatment criteria. Subjects must instill antibacterial eye drops three times a day for three days after Ranibizumab injection.
Subjects will visit the study site monthly during the 12 month study period in order to receive scheduled assessments and evaluate safety and efficacy of treatment. Image interpretation will be performed by a central reading center. The central reading center will confirm eligibility for enrollment and the discrimination of Polypoidal Choroidal Vasculopathy(PCV) at screening and play a role in interpreting whole images of all subjects after the end of the study.

Preclinical data have shown that the herbal extract, ALS-L1023, from Melissa officinalis reduces visceral fat and hepatic steatosis. We aimed to assess the safety and efficacy of ALS-L1023 as the treatment of non-alcoholic fatty liver disease (NAFLD). We conducted a 24-week randomized, double-blind, placebo-controlled 2a study in patients with NAFLD (MRI-proton density fat fraction [MRI-PDFF] ≥ 8% and liver fibrosis ≥ 2.5 kPa on MR elastography [MRE]) in Korea. Patients were randomly assigned to 1800 mg ALS-L1023 (n = 19), 1200 mg ALS-L1023 (n = 21), or placebo (n = 17) groups. Efficacy endpoints included changes in liver fat on MRI-PDFF, liver stiffness on MRE, and liver enzymes. For the full analysis set, a relative hepatic fat reduction from baseline was significant in the 1800 mg ALS-L1023 group (-15.0%, p = 0.03). There was a significant reduction in liver stiffness from baseline in the 1200 mg ALS-L1023 group (-10.7%, p = 0.03). Serum alanine aminotransferase decreased by -12.4% in the 1800 mg ALS-L1023 group, -29.8% in the 1200 mg ALS-L1023 group, and -4.9% in the placebo group. ALS-L1023 was well tolerated and there were no differences in the incidence of adverse events among the study groups. ALS-L1023 could reduce hepatic fat content in patients with NAFLD.

By applying the aroma extract dilution analysis, 13 esters were found to have high FD factors in the Laobaigan flavor type of Baijiu. These were then quantified using GC-MS. In addition, 35 nonvolatile organic acids were quantified by a derivatization method combined with GC-MS. The perceptual interactions of lactic acid and ethyl lactate and that of lactic acid and ethyl acetate were studied through the olfactory threshold. The S curve was used to evaluate the changes in the olfactory thresholds. After adding lactic acid (1142, 20 000, and 53 703 mg/L), the olfactory thresholds of ethyl lactate (1000, 724, and 295 mg/L) and ethyl acetate (398, 324, and 257 mg/L) decreased obviously, which revealed that lactic acid gave additive or synergistic odor effects for the two esters. Furthermore, it was discovered that as the concentrations of lactic acid increased, the extent of the interaction among these compounds was also greater in the mixture.

Abstract:

A great need exists to develop tocolytic and uterotonic drugs that combat poor, labor-related maternal and fetal outcomes. A widely utilized method to assess novel compounds for their tocolytic and uterotonic efficacy is the isometric organ bath contractility assay. Unfortunately, water-insoluble compounds can be difficult to test using the physiological, buffer-based, organ bath assay. Common methods for overcoming solubility issues include solvent variation, cosolvency, surfactant or complexion use, and emulsification. However, these options for drug delivery or formulation can impact tissue function. Therefore, the goal of this study was to evaluate the ability of common solvents, surfactants, cosolvents, and emulsions to adequately solubilize compounds in the organ bath assay without affecting mouse myometrial contractility. We found that acetone, acetonitrile, and ethanol had the least effect, while dimethylacetamide, ethyl acetate, and isopropanol displayed the greatest inhibition of myometrial contractility based on area under the contractile curve analyses. The minimum concentration of surfactants, cosolvents, and human serum albumin required to solubilize nifedipine, a current tocolytic drug, resulted in extensive bubbling in the organ bath assay, precluding their use. Finally, we report that an oil-in-water base emulsion containing no drug has no statistical effect beyond the control (water), while the drug emulsion yielded the same potency and efficacy as the freely solubilized drug.

REGENATIVE LABS AND DR. ROBERT PARKER ANNOUNCE NEW CARE ADVANCEMENTS USING WHARTON'S JELLY ALLOGRAFTS IN ACHILLES TENDON DEFECTS

Improvement of patient-reported pain and functionality warrants future research. The homologous-use application validated by Dr. Parker sets a precedent for non-surgical allograft application. PENSACOLA, Fla., Nov. 7, 2023 /PRNewswire/ -- Regenative Labs (Regenative), a leading HCT/P manufacturer, announces a retrospective case report demonstrating new care advancements using its Wharton's Jelly allografts in the supplementation of Achilles tendon defects. Board-certified in foot and ankle surgery and lower extremity nerve specialist, Dr. Robert Parker of Parker Foot and Ankle in Texas, has presented for publication a novel case study of Wharton's Jelly, an umbilical cord connective tissue, applied to the structural tissue defect of the Achilles tendon in tandem with shock wave and laser therapy. The homologous use application validated by Dr. Parker sets a precedent for non-surgical allograft application. "As practitioners, we all share the knowledge that long-acting steroids, the acetates, are not only detrimental to tendons, they are in my opinion, contraindicated. This is especially true around larger tendons such as the Achilles. We also know the effect of short-acting steroids, the phosphates, though not as destructive, may give some pain relief but do absolutely nothing to help tissues heal themselves. I am very encouraged and optimistic about utilizing umbilical cord connective tissue as a structural allograft which helps my patient's own tissues heal themself even at multiple sites besides the Achille's tendon," shared Dr. Parker. The patient represented in this case report suffered with chronic Achilles tendinosis from chronic enthesopathy at the Achilles tendon insertion with a retrocalcaneal exostosis for three years and has failed standard-of-care practices for over two years. After application of Wharton's Jelly allografts, such as those provided by Regenative, in addition to extracorporeal pulsed-activated therapy (EPAT) and class IV laser therapy treatments, the patient's pain had improved from a 10/10 VAS to a 0/10 VAS in 13 weeks. While Achilles tendonitis and related tendon damage, also known as enthesopathies, is rampant among athletes, it does not exclusively affect athletes. Approximately 65 percent of Achilles injuries diagnosed in general practice are not sport related. Standard care practices for Achilles tendinosis vary from over-the-counter anti-inflammatories or corticosteroid injections with functional rehabilitation therapy to surgical intervention in severe cases. These costs can range upwards of $15k for a surgical repair and do not guarantee complete pain relief. The rising annual number of surgeries is enough to implement conservative protocols alternative to invasive surgical repair of the Achilles tendon. To advance the necessary research and fill the need for non-surgical alternatives, Regenative has been tracking data in its comprehensive retrospective data repository in which physicians across specialties submit patient data as they track patient outcomes up to 120 days after the patient receives an application of Regenative's products, like its Wharton's Jelly allografts. Regenative has collected data from clinics nationwide on Wharton's Jelly applications for Achilles tendon defects and is excited to highlight Dr. Parker's unique procedures in the first of many publications on regenerative podiatric medicine. "Given the high incidence rate and few effective treatment options for defects in the Achilles tendon, this study aims to provide a new, promising alternative intervention for patients who have failed all other standard-of-care treatments. This is just one of many homologous-use applications in regenerative medicine to improve patient outcomes," shared Regenative Labs CEO Tyler Barrett. Barrett is committed to providing patients with alternative options and, through what may be revealed in these studies, offers proven protocols to better address the root cause of their pain. Barrett and his team hope to enlist physicians to take part in studies regarding uncovered uses. Physicians will have their outcomes highlighted, furthering the understanding of regenerative medicine and uncovering new applications for this groundbreaking field of medicine. "We're doing the research at Regenative, and the results are very promising. We are calling on all physicians across the country to engage with us and advance the field of regenerative medicine," Barrett concluded. Contact Regenative to get your practice involved today. About Regenative Labs: Regenative Labs produces regenerative medicine products to address the root cause of a patient's conditions using Wharton's Jelly innovations rather than masking the pain with other treatments.

Regioselectivity, however, remains a formidable challenge in the functionalization of internal alkenes. Here we report a palladium-catalyzed highly regio- and enantioselective remote 1,n-dioxygenation (n ≥ 4) of internal alkenes with engineered pyridine-oxazoline (Pyox) ligands. The reactions proceed efficiently and exhibit a broad substrate scope with excellent regio- and enantioselectivity, affording optically pure 1,n-diol acetates as the key synthons for important bioactive molecules. Experimental studies and density functional theory calculations provide evidence that the regioselectivity is governed by the reactivity disparity of two allylic C–H bonds, where the oxypalladation is reversible and the first palladium migration step proves to be the regioselectivity-determining step, enabled by the modified phenyl-substituted Pyox ligands.Regio- and enantioselective 1,n-dioxygenation of internal alkenesThe catalytic reactions and challenges of design in catalytic remote dioxygenationRegioselective ARD reaction and ligand screening (*ARD: asymmetric remote dioxygenation)Scope of Pd-catalysed remote dioxygenation of internal alkenesSynthetic applicationsSummary and CommentsProf. Guosheng Liu and Zhenyang Lin et al have developed a palladium-catalysed method for the highly regioselective ARD reaction of internal alkenes. Described herein represents a powerful tool for the efficient synthesis of chiral 1,n-diols from simple alkenes. The concept for tuning the regioselectivity of unactivated internal alkenes was demonstrated by altering the rate-determining step, enabled by the modified Pyox ligand, which lays the groundwork for further exploration of other regioselective functionalization reactions.
