Product Information

First-generation IRV-dMNP to deliver 5 µg of IRV were fabricated and stored at 5, 25 or 40 °C for up to 24 months, whereas IPV-dMNP to deliver 20, 4, and 16 DU (half the commercial dose) of IPV types 1, 2, and 3, respectively were fabricated and stored at 5 or 25 °C for up to 12 weeks. IPV-dMNP stability at 40 °C was not evaluated. The dMNP were tested for IRV or IPV potency by ELISA using a rotavirus VP7-specific monoclonal antibody or monoclonal antibodies to poliovirus types 1, 2, and 3 25, 40. All dMNP were monitored for appearance (e.g., specified number of MNs, free of debris, appropriate shape, and color) throughout the stability studies. Animal studies The microneedles used in this study are made from a mixture of dissolvable sugar and a polymer called PVA, as well as the quantum-dot dye and the vaccine. When the patch is applied to the skin, the microneedles, which are 1.5 millimeters long, partially dissolve, releasing their payload within about two minutes. Relatively large quantities of therapeutic ingredients may be supplied into the skin with the “poke and flow” approach, which, by using hollow MNs, could potentially overcome the dose limitation associated with solid MNs [ 49]. With hollow MNs, it is technically possible to control the flow and dosing by diffusion or pressure or electronically (e.g., using a pump), and to integrate them into lab-on-chip devices. Similarly, bio-macromolecules, including proteins, vaccines, mRNA, and diagnostic agents, can be delivered via hollow MNs [ 50, 51]. These MNs can also be used for the isolation and identification of biomarkers including glucose [ 52], and ECG measurements [ 53]. Nonetheless, the construction of hollow MNs is relatively complicated and suffers from clogging, drug leakage, structural fragility, and the requirement of a larger tip diameter, which leads to poor insertion.

Microneedle patch as a new platform to effectively deliver Microneedle patch as a new platform to effectively deliver

The pipeline of HD-MAP products in development at Vaxxas, and other MAP developers, has been growing in recent years. In 2021, there are new opportunities for the development of COVID-19 and mRNA vaccines on HD-MAPs, as two recent studies have indicated: Rouphael, N. G. et al. The safety, immunogenicity, and acceptability of inactivated influenza vaccine delivered by microneedle patch (TIV-MNP 2015): a randomised, partly blinded, placebo-controlled, phase 1 trial. Lancet 390, 649–658 (2017). Thomas, Liji. "Microneedle patches for potential COVID-19 vaccines or therapeutics". News-Medical. 02 November 2023. .Two or three doses of standalone IPV or combined IRV-IPV in the first-generation dMNP at full or half dose induced protective titers (≥1:8) of NA to the corresponding PV types 1, 2, and 3 in rats (Fig. 5d–f). The differences in antibody titer between post-vaccine doses 2 and 3 of full dose standalone IPV and full IRV-IPV were not statistically significant. Similarly, the differences in antibody titer between post-vaccine doses 2 and 3 of full-dose IPV, full-dose IRV-IPV, and half-dose IPV or half-dose IRV-IPV were not statistically significant. Of the three IPV types, IPV 2 was the most immunogenic and induced high geometric mean titers (GMTs) to PV type 2 even with a single dose. Anyone with acne prone skin needs to be careful of microneedling using a dermaroller as these devices can spread the acne causing bacteria around the skin, and potentially cause acne spots to spread. The main benefit of microneedle patches is obviously that they’re targeted to a specific area of skin, but they’re also safe. Since they cause no trauma to the skin, you won’t feel a thing (aside from a satisfying tingle indicating that they’re working) and they won’t cause any bleeding unlike dermarollers which are considerably more aggressive.

What Are Microneedle Patches and How Do They Work? - VICE REVERSA

The speed of vaccine development and deployment in response to the COVID-19 outbreak has been remarkable. It has also laid bare many challenges in the delivery of vaccines to all the populations that need them. Mass vaccination of populations using N&S relies on trained health professionals, who are often in short supply, especially during pandemics. The need for multi-dose COVID vaccination regimens, including booster shots, and for billions of people around the world is predicted to exacerbate shortcomings in vaccination systems and extend to many vaccines beyond those to protect against SARS-CoV-2. The consequences of inadequate global vaccine coverage are already apparent for many diseases and progress in childhood vaccine coverage globally has already stalled, with an estimated 14.5 million ‘zero-dose’ children in 2019, i.e. children who did not receive a single dose of a diphtheria, tetanus, and pertussis-containing vaccine (used as a measure of children not reached by routine vaccination services). 7 The emergence of successive variants of concern (VoCs) initiating new waves of SARS-CoV-2 infection is prolonging this pandemic, delaying global post-pandemic recovery and will have a continuing impact on vaccination systems around the world. Storage, access, and control of medical records is an important topic with many possible approaches,” says Mark Prausnitz, chair of chemical and biomolecular engineering at Georgia Tech, who was not involved in the research. “This study presents a novel approach where the medical record is stored and controlled by the patient within the patient’s skin in a minimally invasive and elegant way.” By selectively loading microparticles into microneedles, the patches deliver a pattern in the skin that is invisible to the naked eye but can be scanned with a smartphone that has the infrared filter removed. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. John, J. et al.

Vaccine MAP developers are entering new territory with respect to manufacturing processes, capability, and infrastructure. Advanced pilot manufacturing runs will be required to demonstrate to, and assure, key players in the vaccine industry that a new vaccine MAP platform will be cost-effective to manufacture at scale compared with the existing well-established N&S. Antigen casting solutions for second-generation dMNP were prepared at lower vaccine concentrations while keeping the ratio of vaccine to excipient constant. To fabricate full dose IRV dMNP, casting solutions had a concentration of 0.625 mg/ml IRV, 2% w/v sucrose (VWR, OH, USA) and 0.4% w/v sodium methylcellulose. IPV casting solutions had a concentration of 5.8, 1.1, and 5.2 DU/μl of types 1, 2, and 3, respectively, 1.5% w/v maltodextrin (Sigma-Aldrich, MO, USA) and 0.5 % w/v xylitol. Full-dose combination patches were prepared to deliver 5 μg IRV and 40, 8, and 32 DU of IPV types 1, 2, and 3, respectively. Solutions for manufacturing the quarter dose dMNP contained lower vaccine doses while keeping the excipient concentrations constant. After deposition of the polymer matrix solution, all MN arrays were dried at 35 °C overnight. Stability studies In contrast to ISF extraction, microneedles functionalized with biorecognition elements can specifically capture target biomarkers in ISF, which can be followed by ex vivo analysis 17, 18. Direct exposure of microneedles to ISF allows the biorecognition elements on the microneedle to capture target biomarkers in situ, thus offering a promising technology for simple and efficient biodetection. However, physiological concentrations of the protein biomarkers in the ISF are usually lower compared to those in blood 4, 19. Moreover, analyte–antibody binding kinetics are deteriorated due to the dense tissue environment, which results in slower diffusion of target biomolecules to the sensor surface (that is, the microneedle surface), further lowering the probability of analyte capture and consequent signal intensity corresponding to the analyte. These challenges exacerbate the difficulty of detection of protein biomarkers in interstitial fluid. Despite the recent advances in multiplexed detection of biomarkers 20, the sensitivities of existing microneedle-based analytical methods are insufficient to detect (or quantify) most ISF protein biomarkers, which limits the development potential for diagnostic tests based on ISF biomarker levels. Most previous reports are limited to mice that have been intravenously injected with high concentrations of recombinant target markers as pseudo models, or to biomolecules present at relatively high levels (micrograms per millilitre in blood) 17. Finally, existing microneedle-based in vivo sampling and detection methods are limited to qualitative analysis in which the target biomarker concentration is represented as relative fluorescence intensity, absorbance value or normalized relative quantity 18, 20, 21. This limitation precludes quantitative comparisons of the biomarker concentrations across different experiments and across different laboratories for biomedical research and decreases opportunities for standardization of the cut-off values for clinical biomarkers. Microneedles were first mentioned in a 1998 paper by the research group headed by Mark Prausnitz at the Georgia Institute of Technology that demonstrated that microneedles could penetrate the uppermost layer ( stratum corneum) of the human skin and were therefore suitable for the transdermal delivery of therapeutic agents. [8] Subsequent research into microneedle drug delivery has explored the medical and cosmetic applications of this technology through its design. This early paper sought to explore the possibility of using microneedles in the future for vaccination. Since then researchers have studied microneedle delivery of insulin, vaccines, anti-inflammatories, and other pharmaceuticals. In dermatology, microneedles are used for scarring treatment with skin rollers. The major goal of any microneedle design is to penetrate the skin's outermost layer, the stratum corneum (10-15μm). [9] Microneedles are long enough to cross the stratum corneum but not so long that they stimulate nerves which are located deeper in the tissues and therefore cause little to no pain. [8]
