Abstract
Description
[Technical field]
[0001] This application claims priority from Chinese patent application No. 202111522472X, filed on December 13, 2021. The entire text of the above Chinese patent application is incorporated herein by reference.
[0002] The present invention relates to the field of biomedicine technology, specifically to a manufacturing system and method for the continuous and scaled production of nano-formulations, specifically, the related manufacturing method involves the rapid mixing of a two-phase solution by the action of turbulent shear and at the same time the action of ultrasound to form a nano-formulation with stable and consistent particle size and particle size distribution, the manufacturing method has excellent stability, high reproducibility, can be scaled up step by step, and is suitable for the continuous and scaled production of nano-formulations.
[0003] The present invention belongs to the field of nanomedicine formulation technology. [Background technology]
[0004] In the process of tumor treatment, there are various treatment plans that can extend the survival time of tumor patients. Antitumor drugs used in treatment plans include chemotherapy drugs, targeted drugs, photosensitive molecules, photothermal molecules, polypeptides, proteins, siRNA, etc., among which, some drugs need to be manufactured into nano dosage forms to achieve the therapeutic effect of tumors. Common nano formulation forms include nanoparticles, nanoliposomes, polymer nanomicelles, dendrimers, etc.
[0005] Currently, large-scale manufacturing methods for nano-formulations include high-pressure homogenization, high-shear emulsification, microjet homogenization, etc., but these manufacturing methods are batch manufacturing and have disadvantages such as many process control parameters, low batch-to-batch reproducibility, and difficulty in scale-up production.
[0006] Compared with the batch manufacturing method, the continuous manufacturing method of nanoformulations can form uniform nanoparticles with adjustable size in the continuous operation process, and by monitoring the quality of the nanoformulations in real time during the production process, the nanoformulations that meet the quality standards can be collected in real time.
[0007] For example, in the case of liposome systems, continuous production can be achieved using the ethanol injection method. A microfluidic control device from Precision NanoSystems, Canada, can be used to continuously produce liposomes (Langmuir, 2012, 28, 3633), which uses laminar flow of lipid organic phase and aqueous phase to rapidly mix in a staggered static mixer and continuously produce liposomes through parameter optimization, but since the microfluidic control flow pipe is usually at the micron level, the flow of the fluid is under laminar flow conditions, the yield of a single passage is extremely small, and parallel multiple passages are required for expanded production, and the consistency of each liposome production unit needs to be controlled. A continuous blank liposome production device using the ethanol injection method disclosed in the literature (Pharm Res., 2016, 33, 404-416) and the invention patent (CN201680013882) can obtain blank liposomes with a low polydispersity coefficient by adjusting the flow rates of the ethanol phase and the aqueous phase, respectively.
[0008] For polymer / drug nanoparticle systems, they can be continuously produced by flash nanoprecipitation (FNP) (US10940118B2, CN108137819, CN108542894). Flash nanoprecipitation is based on the principle of dynamics control and utilizes fluid turbulence mixing in chemical engineering to realize the rapid production of nanoparticles, which has the characteristics of high drug loading rate, short production time (millisecond level), easy control of nanoparticle size, and easy expansion and continuous production. The principle of the preparation of drug / polymer nanoparticles by nanoprecipitation is that a carrier or stabilizer (usually an amphiphilic polymer) and a hydrophobic drug are dissolved in a good solvent that is miscible with water to form a homogeneous solution, and the solution is rapidly mixed with an antisolvent (usually water) in a fixed channel. At this time, the hydrophobic substance is in a highly supersaturated state in the mixed solvent, so that the hydrophobic substance rapidly nucleates in water, and at the same time, the hydrophobic substance interacts with a polymer (usually an amphiphilic block polymer) in the solution, and the polymer coats the core of the nucleation to form polymer nanoparticles, and the polymer plays a protective effect on the nanoparticles and prevents the formed nanoparticles from re-agglomerating, thus forming nanoparticles with good dispersibility in water (Expert Opin. Drug Deliv., 2009, 6, 865). Production equipment used in flash nanoprecipitation includes the confined impinging jet mixer (CIJM) (Physical Review Letters, 2003, 91, 118301; AIChE Journal, 2003, 49, 2264) and the multi-inlet vortex mixer (MIVM) (Mol. Pharm., 2013, 10, 4367; Angew. Chem. Int. Ed. Engl., 2021, 60, 15590).
[0009] However, when the nanoparticles of hydrophobic drugs are continuously produced by conventional flash nanoprecipitation (FNP), the reproducibility of the nanopreparation production process is low due to the significant drop in the encapsulation rate of the hydrophobic drug and the increase in the particle size distribution coefficient of the nanopreparation during the expansion production process of the nanopreparation, making it difficult to control the quality of the nanopreparation, and increasing the risk of failure during the expansion production process of the nanopreparation.In addition, in the prior art, in order to reduce the particle size, ultrasonic waves are combined with the microfluidic control technology of non-turbulent flow state to produce blank liposomes, but the blank liposomes are not related to the parameter of the encapsulation rate of the drug, so how to improve the encapsulation rate of the hydrophobic drug during the expansion production process of the nanopreparation is still an urgent problem to be solved. Summary of the Invention
[0010] The technical problem solved by the present invention overcomes the defects and shortcomings of the above-mentioned prior art, and through repeated research and testing, it has been found that by mixing two-phase solution under conditions of simultaneous turbulent shear action and ultrasonic action, it is possible to solve the problems of the decrease in drug encapsulation rate and the decrease in particle size uniformity of nano-preparations that occur in the scale-up production process of nano-preparations, thereby providing continuous, scalable and controllable production equipment for nano-preparations and a method for continuous, scalable production of ultrasound-enhanced nano-preparations, and realizing continuous, controllable scale-up production of nano-preparations.
[0011] The first objective of the present invention is to provide an equipment for continuous, scalable and controllable production of nano-formulations, which can promote the formation of nanoparticles, improve the encapsulation rate of nano-drugs, prevent the deposition of hydrophobic drug particles on the tube wall, and improve the uniformity of nanoparticle size.

[0019] In some embodiments, the mixing is turbulent mixing. The turbulent mixing can be achieved by increasing the number of turbulent mixing devices in the merging conduit. The turbulent mixing devices can be one or more.
[0020] In some embodiments, the first conduit outlet is a nozzle having a certain shape and aperture size, and the first phase solution passes through the first conduit and out of the nozzle into the merging conduit.

[0022] In some embodiments, the length of the merging conduit (ie, the length of the merging phase) is in the range of 6 cm to 120 cm, for example 9 cm or 36 cm.
[0023] In some embodiments, the ratio of the length of the merging conduit to the inner diameter of the merging conduit is (16-450):1, such as 16.7:1, 30:1, or 450:1.

[0034] In some embodiments, the turbulent mixing can increase the flow velocity of the fluids, which can cause the fluids in the merging phase to reach a turbulent transition state or a turbulent state.

The static mixer includes, but is not limited to, an SV type static mixer, an SX type static mixer, an SL type static mixer, an SH type static mixer, an SK type static mixer, etc., and the turbulent mixing member divides the fluid / changes the flow direction of the fluid / increases the convection of the fluid to increase the mixing of the fluid.
