Cardiovascular Disease Treatment
Gold nanoparticles were coated with the client’s proprietary biologic to target and treat cardiovascular disease. The gold nanoparticle cores served as both a biocompatible scaffold and a means to track the pharmacokinetics of the platform. nanoComposix completed a technology transfer of the client’s existing analytical methods and processes, successfully scaled the procedure from a milliliter to a liter scale for future manufacturing, and optimized the lyophilization and storage conditions of the therapeutic.
Nanoparticles for Immunotherapy
nanoComposix engaged in close collaboration with a client to comprehensively develop and manufacture a cutting-edge PLGA nanoparticle-based immunotherapy. Work began by successfully integrating the client’s API into a nanoparticle tailored to the unique requirements of the therapy and progressed through scale-up, process development, transfer to manufacturing, and the production of GMP material for Phase I and Phase II clinical trials.
Antibacterial Silver Nanoparticles for Use in a Wound Dressing
A physician client treating patients with diabetic wounds contacted nanoComposix to manufacture silver particles to be used on the surface of a wound compression dressings. The resulting product was utilized in a medical case study for the treatment of wounds and diabetic ulcers.
Photothermal Nanoparticle for Hair Removal
nanoComposix assisted in the development and manufacture of a photothermal hair removal treatment for Sienna Biopharmaceuticals. This topical therapeutic utilized silica-shelled silver nanoplates that were developed and optimized by nanoComposix, first under R&D controls and later under the NCX Quality Management System. During the R&D phase, nanoComposix developed a process to fabricate and encapsulate nanoplates for prototyping and proof of concept demonstration in pilot studies.
Technical Transfer of a GMP Topical Photothermal Therapeutic
A client required a second source for a topical acne therapeutic with a nanoparticle component. A Manufacturing Master Record (MMR) and Manufacturing Batch Records (MBRs) were provided to nanoComposix for all intermediates, and the synthesis of the nanoparticle component was successfully replicated at nanoComposix. Engineering runs were performed using draft batch records while additional test methods were developed and validated as required. nanoComposix led qualification of all raw material suppliers. qualification. A cGMP-compliant qualification batch and commercial GMP lots were produced and delivered to the client.
Targeted Silica-coated Iron Oxide Nanoparticles for in-vivo Delivery to Tumors
Magnetite nanoparticles with a silica shell were designed by nanoComposix and functionalized with a humanized anti-prostate-specific membrane antigen using a covalent binding strategy for cell-specific targeting. Non-specific binding was minimized via the development of a mixed monolayer of polyethylene glycol molecules at the particle surface. Feasibility testing showed these nanoparticles were extremely stable and had excellent specific targeting ability. In-vivo data showed targeted delivery and tumor reduction when the magnetic nanoparticles were heated via an applied alternating magnetic field.
Development to GMP Manufacture of a Mesoporous Silica Based Cancer Therapeutic
A pharmaceutical company approached nanoComposix to develop mesoporous silica particles as a key component in their cancer immunotherapy.
