The Power of Cannabis Hairs Revealed With Microscopy, Genetic Testing

LabRoots | November 01, 2019

A recent study from the University of British Columbia, published in The Plant Journal examined the hairs, or glandular trichomes, of cannabis plants. The structures and chemical outputs of various hairs were studied through microscopy and chemical profiling. The plant sample used was a quick-flowering variety of hemp Cannabis sativa known as “Finola.” The largest and mushroom-shaped “stalked” plant hairs were discovered to be the most potent; they produced the most THC- and CBD-forming metabolites and scent-producing terpenes. This fact has been previously suspected but unproven within the cannabis community. Earlier studies categorized the cannabis plant hairs as either bulbous, sessile or stalked, based on how they looked. But how they actually affected the strength of the plant’s effects was unknown. A gene expression analysis and UV light examinations helped the researchers to better understand the hairs’ properties. "We saw that stalked glandular trichomes have expanded ‘cellular factories’ to make more cannabinoids and fragrant terpenes. We also found that they grow from sessile-like precursors and undergo a dramatic shift during development that can be visualized using new microscopy tools,” co-lead author and Botany Ph.D. candidate Sam Livingston said.

iTolerance to Collborate with LyGenesis for Joint Research

iTolerance | July 01, 2022

iTolerance, Inc., an early-stage privately held regenerative medicine company developing technology to enable organoid, tissue, and cell therapy, announced entering into a joint collaboration with LyGenesis, Inc., a clinical-stage biotechnology company with an organ regeneration technology platform. The joint collaboration is aimed at evaluating the potential of iTOL-201, a product candidate being developed combining LyGenesis' LYG-LIV-100 liver cell therapy and iTolerance's SA FasL microgel immune tolerance platform to permit the growth of ectopic livers without the requirement for immune suppression. The joint research effort of iTolerance and LyGenesis has produced in vitro data using iTOL-201 and is now moving toward small animal proof of concept work to assess the potential of the combined technology for producing ectopic livers capable of saving the animals from fatal liver disorders without the requirement for immune suppression. With our lead therapy now in the clinic in a Phase 2a trial in patients with End Stage Liver Disease, we have turned our attention toward a second-generation therapy capable of growing ectopic organs without the need for immune suppression. iTolerance's platform holds enormous promise in this respect and we look forward to the results from our joint proof of concept work." Dr. Michael Hufford, Co-Founder and Chief Executive Officer of LyGenesis. While long-term immunosuppression continues to be an obstacle for the use of cell and regenerative therapies, the research being conducted between both LyGenesis and iTolerance could allow for a major advancement in organ regeneration, As we advance our own pipeline of therapies focused on supporting pancreatic islet engraftments, I believe this synergistic collaborative research with LyGenesis has the potential to successfully combine technologies to drive significant value for both biotech companies and importantly, the patients we work to serve." Dr. Anthony Japour, Chief Executive Officer of iTolerance.

Novaliq submits New Drug Application seeking approval for first-of-a-kind Dry Eye Disease Treatment CyclASol®

Novaliq GmbH | August 10, 2022

Novaliq, a biopharmaceutical company focusing on first- and best-in-class ocular therapeutics based on the unique EyeSol® water-free technology, announced the submission of a New Drug Application to the U.S. Food and Drug Administration seeking approval for CyclASol® a proposed novel treatment for the signs and symptoms of dry eye disease. CyclASol® has demonstrated in two pivotal studies fast onset of therapeutic effect in the indication, clinical meaningful improvement of ocular surface damage, and excellent tolerability. Results from a 12-month long-term study confirmed that the effects are maintained, and even improved for most sign and symptom endpoints. "This is the first submission of a novel product category of water-free topical drug therapies utilizing EyeSol® as a drug carrier. CyclASol® is a first-of-a-kind drug therapy and aims to expand treatment success for patients with dry eye disease and their eye care professionals. If approved by the FDA, CyclASol® addresses important unmet medical needs in DED through its ocular surface healing effect combined with high comfort of administration." Christian Roesky, Ph.D., CEO, Novaliq Dry eye is one of the most common ocular surface disorders, with approximately 18 million Americans diagnosed with DED.1,2 Inflammation and immunologic processes play a key role in the pathology of the disease. A compromised ocular surface secondary to DED may also compromise refractive measurements before keratorefractive and phacorefractive surgeries and adversely impact expected visual outcomes after these surgeries.3,4 The impact of the corneal surface damage secondary to DED on visual function is an underestimated aspect of the disease. Multiple guidelines recommend treatment of the corneal surface damage prior to ocular procedures. A high unmet need remains for better tolerated drugs with an early onset of therapeutic effect, which are compelling to be used and prescribed.5,6 "We are very proud to see another product rapidly moving to the market, which marks yet another important inflection point and milestone in Novaliq's growth trajectory", said Dr. Mathias Hothum, board member and managing director of dievini. "We are currently evaluating the commercialization strategies which includes talking to interested parties." About CyclASol® CyclASol® is a first-of-a-kind topical treatment of cyclosporine, a potent anti-inflammatory and selective immunomodulatory drug. Whilst not water-soluble, cyclosporine is soluble in the EyeSol® excipient perfluorobutylpentane allowing for its improved bioavailability and better efficacy on the target tissue. The product contains no oils, no surfactants and is preservative-free due to the novel carrier. This provides additional clinical benefits for patients, such as improved tolerability and decreased visual disturbances. The NDA is supported by safety and efficacy results in over 1,000 patients with DED from a Phase 2 dose finding study, the Phase 2b/3 ESSENCE-1 study, the Phase 3 ESSENCE-2 study and its open label extension study.7,8 CyclASol® has demonstrated in two independent adequate and well-controlled, multicenter studies clinically meaningful and statistically significant improvements in the indication. Effects on the ocular surface include a statistically significant reduction in total corneal fluorescein staining score favoring CyclASol® in both studies at Days 15 and 29. Up to 71.6% of patients responded within four weeks with a clinically meaningful improvement of ≥ 3 grades in total corneal staining. This proportion of responders was significantly higher compared to vehicle-treated patients in both studies. Responders showed also statistically significant improvements in a variety of symptoms compared to non-responders at day 29. The ASCRS guidelines recognize corneal staining as the single most important clinical sign of DED as it indicates the level of epithelial damage and visual impairment, and if left undertreated, DED can become chronic and more difficult to treat.3 Effect on tear production: In both studies, compared to vehicle at the end of treatment, there was a statistically significant (p<0.05) higher percentage of patients with increases of ≥ 10 mm from baseline in Schirmer's tear test score at Day 85 and Day 29, respectively, confirming a known effect of the active ingredient cyclosporine. Meeting this endpoint in two independent studies is clinically meaningful on its own and considered to demonstrate efficacy for the treatment of signs and symptoms of DED. Head-to-head data versus Restasis™ from the phase 2 study suggest that CyclASol® has a stronger and faster therapeutic effect on the ocular surface.8 Maintenance of effect results from the long-term study CYS-005 confirmed that the effect of CyclASol® was maintained, and even improved for most endpoints, over the 52-week treatment period. Safety and Tolerability: Tolerability of CyclASol® was shown by high drop comfort patient ratings in both studies. The most common adverse reaction observed was instillation site reactions, which was reported in 8.1% of patients in the pooled studies. These were in all but one case mild. The only other adverse reaction reported in > 2% of the patients was visual acuity reduced (2.7%).
