Initial Experiences with the Envoy Acclaim^® Fully Implanted Cochlear Implant.

Article

作者: Lawlor, Skye K ; Driscoll, Colin L W ; Dornhoffer, James R ; Saoji, Aniket A

Introduction: Cochlear implantation has become the standard of care for the treatment of moderate-to-profound bilateral sensorineural hearing loss. However, current technologies, all of which rely on an external sound processor, have intrinsic limitations that prevent certain activities and diagnostics, thus hampering full integration into a patient's lifestyle. The Envoy Medical (White Bear Lake, MN, USA) Acclaim^® fully implanted cochlear implant is a new device currently undergoing testing that has been designed to alleviate many of the current constraints by housing all components within the patient, thus allowing for near-constant use in many environments that are not conducive to a traditional cochlear implant. Methods: As part of an Early Feasibility Study, three adult implant candidates were implanted with the Acclaim^® cochlear implant. Surgical video and photography were taken, and initial observations were recorded. Implantation with the Acclaim^® device is largely similar to a traditional cochlear implant, with modifications to allow room for the implanted sensor as well as the implantation of a battery in the subcutaneous tissues of the chest. Results: This study demonstrates a step-by-step overview of implanting the Acclaim^® and discusses initial insight and experiences with the first three implantations with this new device. Conclusions: All three surgeries proceeded without complication, and at activation, all three patients were hearing through their devices. Surgery is more technically challenging compared to a standard cochlear implant, but the skills needed can all be mastered by a dedicated otologic surgeon.

A Systematic Review on the Effect of Strontium-Doped Nanohydroxyapatite in Remineralizing Early Caries Lesion

Review

作者: Ashik P, Mohammed ; M, Ameena ; Rajendran, Ratheesh ; Hameed, Hana ; Paul, Princy ; Antony, Delphine P

The aim of this study is to review the potential of strontium-doped nanohydroxyapatite (SrnHAP) as a biomaterial for remineralizing early carious lesions. Publications from 2012 to 2022 were included based on the patient/population, intervention, comparison, and outcomes (PICO) framework, focusing on demineralized enamel treated with strontium-doped nanohydroxyapatite compared to other remineralizing agents, with the primary outcome being remineralization capacity. Electronic databases, namely, PubMed, Cochrane Library, and Google Scholar, were explored from March 31, 2023, to April 10, 2023. Only English language studies were included, while certain research types and studies on bovine teeth were excluded. Bias was assessed using the Cochrane methodology. Five studies were synthesized, all using extracted human maxillary premolars. Four studies focused on remineralizing enamel, while one study focused on remineralizing dentin. Among these studies, comparisons were made between different strontium concentrations and various remineralizing agents such as nanohydroxyapatite (nHAP), Acclaim, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and NovaMin. X-ray diffraction analysis was used to examine hydroxyapatite formation, while scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for characterization. Additionally, one study evaluated the mechanical properties of partially demineralized dentin specimens. This study was registered in the PROSPERO under the ID CRD42023397413 and completed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Comparison of Remineralization Potential of Casein Phosphopeptide: Amorphous Calcium Phosphate, Nano-hydroxyapatite and Calcium Sucrose Phosphate on Artificial Enamel Lesions: An In Vitro Study

Article

作者: Reddy, Divya ; Azher, Umme ; Sebastian, Ronin ; Paul, Santhosh T

Aim and objectiveTo evaluate and compare the remineralization potential of CPP-ACP, nano-hydroxyapatite, and calcium sucrose phosphate toothpaste on artificial enamel caries lesions by means of microhardness testing.Materials and methodsTwenty sound human primary molars, extracted for therapeutic reasons were selected for this study. From each tooth, two enamel specimens were prepared and embedded in acrylic resin blocks, and each block contains five tooth samples. After polishing, the baseline hardness of the enamel surface (KHN) was determined by Knoop microhardness testing. Then the specimens were randomly assigned into four groups (n = 10), according to the remineralizing agent used: group I: Control, group II: GC Tooth Mousse^TM (CCP-ACP), group III: Acclaim^TM (nano-HAP), and group IV: EnaFix (CaSP). The specimens were then immersed in a demineralizing solution and post-lesion KHN values were obtained as baseline measurements. Later remineralizing agent was applied and after 7 days of remineralization, posttreatment KHN tests were conducted.ResultsData were analyzed using paired t- test, analysis of variance, and Tukey HSD test. Mean enamel surface microhardness (KHN) values after remineralization shows that group IV (EnaFix^TM) had maximum hardness number (114.71 ± 12.27) followed by group III (Acclaim) (85.14 ± 22.82) and group II (GC Tooth Mousse) (56.42 ± 19.90). The difference was statistically significant (p < 0.001). Similarly the %SMHR was also highest in group IV (EnaFix), followed by group III (Acclaim) and group II (GC Tooth Mousse).ConclusionEnaFix (calcium sucrose phosphate) shows a maximum increase in the enamel surface microhardness followed by Acclaim (nano-HAP) and GC Tooth Mousse.Clinical significanceCalcium Sucrose Phosphate in toothpaste strengthened the enamel more than nano hydroxyapatite and CPP-ACP, and can be an alternative to the use of fluoride toothpaste in children.How to cite this articleSebastian R, Paul ST, Azher U, et al.

Genprex Receives Notice of Patent Grant for Korean Patent Claiming Reqorsa® Immunogene Therapy with PD-1 and PD-L1 Antibodies to Treat Cancers

Expands on the previously granted patents covering the use of REQORSA in combination with immune checkpoint inhibitors applicable to Genprex's Acclaim-2 and Acclaim-3 clinical trials AUSTIN, Texas, March 12, 2024 /PRNewswire/ -- Genprex, Inc. ("Genprex" or the "Company") (NASDAQ: GNPX), a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes, today announced that the Korean Patent Office has issued a Notice of Patent Grant for a broad patent that covers the use of Genprex's lead drug candidate, Reqorsa® Immunogene Therapy, in combination with anti-PD-1 and PD-L1 antibodies through 2037. This patent will expand on the previously granted patents in the U.S., Japan, Mexico, Russia, Australia, Chile and China to cover the use of REQORSA in combination with immune checkpoint inhibitors, e.g., PD-1 and PD-L1 inhibitors. These patents are applicable to Genprex's Acclaim-2 and Acclaim-3 clinical trials. "We continue to secure exclusivity for our drug combinations of REQORSA with PD-1 antibodies, such as Keytruda® and PD-L1 antibodies, such as Tecentriq®, for the treatment of cancer in some of the largest markets," said Thomas Gallagher, Esq., Senior Vice President of Intellectual Property and Licensing at Genprex. "It is important that we continue to add to our global intellectual property estate and to build protection around our drug combinations as we advance REQORSA through the clinic." The Acclaim-2 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2a expansion portion, and a Phase 2b randomized portion. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.'s Keytruda® in patients with late-stage non-small cell lung cancer (NSCLC) whose disease has progressed after treatment with Keytruda. Patients are treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to the Acclaim-2 SRC approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. Genprex expects to complete enrollment in the Phase 1 dose escalation portion of the Acclaim-2 study in the second half of 2024. Genprex was granted FDA Fast Track Designation for the Acclaim-2 patient population. The Acclaim-3 study has two portions - a Phase 1 dose escalation portion and a Phase 2 expansion portion. In November 2022 Genprex filed with the FDA the protocol for the Phase 1/2 Acclaim-3 clinical trial using a combination of REQORSA and Genentech's Tecentriq® as maintenance therapy for patients with extensive stage small cell lung cancer (ES-SCLC) who develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. The Phase 1 portion of the Acclaim-3 study is open for enrollment, and Genprex expects to complete the Phase 1 portion of the study by the second half of 2024. Genprex was granted FDA Fast Track Designation and Orphan Drug Designation for the Acclaim-3 patient population. About Genprex, Inc. Genprex, Inc. is a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes. Genprex's technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations with cancer and diabetes who currently have limited treatment options. Genprex works with world-class institutions and collaborators to develop drug candidates to further its pipeline of gene therapies in order to provide novel treatment approaches. Genprex's oncology program utilizes its systemic, non-viral Oncoprex® Delivery System which encapsulates the gene-expressing plasmids using lipid nanoparticles. The resultant product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. The Company's lead product candidate, Reqorsa® Immunogene Therapy (quaratusugene ozeplasmid), is being evaluated in three clinical trials as a treatment for NSCLC and SCLC. Each of Genprex's three lung cancer clinical programs has received a Fast Track Designation from the FDA for the treatment of that patient population, and Genprex's SCLC program has received an FDA Orphan Drug Designation. Genprex's diabetes gene therapy approach is comprised of a novel infusion process that uses an AAV vector to deliver Pdx1 and MafA genes directly to the pancreas. In models of Type 1 diabetes, GPX-002 transforms alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body's immune system. In a similar approach, GPX-003 for Type 2 diabetes, where autoimmunity is not at play, is believed to rejuvenate and replenish exhausted beta cells.
