3D Printed Drug Delivery Systems in Action–Magnetic Resonance Imaging and Relaxometry for Monitoring Mass Transport Phenomena

Article

Author: Dorożyński, Przemysław ; Milanowski, Bartłomiej ; Birczyński, Artur ; Baran, Ewelina ; Kulinowski, Piotr ; Klaja, Jolanta ; Nowak, Piotr

The hypothesis of the study was that (1) 3D printed drug delivery systems (DDS) could be characterized in situ during drug release using NMR/MRI techniques in terms of mass transport phenomena description (interfacial phenomena), particularly for systems dealing with two mobile phases (e.g., water and low molecular weight liquid polymer); (2) consequently, it could be possible to deduce how these interfacial mass transport phenomena influence functional properties of 3D printed DDS. Matrix drug delivery systems, prepared using masked stereolithography (MSLA), containing poly(ethylene glycol) diacrylate (PEGDA) and low molecular weight polyethylene glycol (PEG) with ropinirole hydrochloride (RH) were studied as example formulations. The PEGDA to PEG (mobile phase) concentration ratio influenced drug release. It was reflected in spatiotemporal changes in parametric T₂ relaxation time (T₂) and amplitude (A) images obtained using magnetic resonance imaging (MRI) and T₁-T₂ relaxation time correlations obtained using low-field time-domain nuclear magnetic resonance (LF TD NMR) relaxometry during incubation in water. For most of the tested formulations, two signal components related to PEG and water were assessed in the hydrated matrices by MRI relaxometry (parametric T₂/A images). The PEG component faded out due to outward PEG diffusion and was gradually replaced by the water component. Both components spatially and temporally changed their parameters, reflecting evolving water-polymer interactions. The study shows that dynamic phenomena related to bidirectional mass transport can be quantified in situ using NMR and MRI techniques to gain insight into drug release mechanisms from 3D printed DDS systems.

Induced pluripotent stem cells‐based disease modeling, drug screening, clinical trials, and reverse translational research for amyotrophic lateral sclerosis

Review

Author: Kato, Chris ; Morimoto, Satoru ; Nakahara, Jin ; Takahashi, Shinichi ; Okano, Hideyuki

Abstract:

It has been more than 10 years since the hopes for disease modeling and drug discovery using induced pluripotent stem cell (iPSC) technology boomed. Recently, clinical trials have been conducted with drugs identified using this technology, and some promising results have been reported. For amyotrophic lateral sclerosis (ALS), a devastating neurodegenerative disease, several groups have identified candidate drugs, ezogabine (retigabine), bosutinib, and ropinirole, using iPSCs‐based drug discovery, and clinical trials using these drugs have been conducted, yielding interesting results. In our previous study, an iPSCs‐based drug repurposing approach was utilized to show the potential of ropinirole hydrochloride (ROPI) in reducing ALS‐specific pathological phenotypes. Recently, a phase 1/2a trial was conducted to investigate the effects of ropinirole on ALS further. This double‐blind, randomized, placebo‐controlled study confirmed the safety and tolerability of and provided evidence of its ability to delay disease progression and prolong the time to respiratory failure in ALS patients. Furthermore, in the reverse translational research, in vitro characterization of patient‐derived iPSCs‐motor neurons (MNs) mimicked the therapeutic effects of ROPI in vivo, suggesting the potential application of this technology to the precision medicine of ALS. Interestingly, RNA‐seq data showed that ROPI treatment suppressed the sterol regulatory element‐binding protein 2‐dependent cholesterol biosynthesis pathway. Therefore, this pathway may be involved in the therapeutic effect of ROPI on ALS. The possibility that this pathway may be involved in the therapeutic effect of ALS was demonstrated. Finally, new future strategies for ALS using iPSCs technology will be discussed in this paper.

Parkinson's disease drug ropinirole safely slowed the progression of ALS for over 6 months in a clinical trial

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal motor neuron disease that causes people to gradually lose control of their muscles. There is no cure, and current treatments focus on reducing symptoms and providing supportive care. Researchers now show in an early clinical trial that the Parkinson's disease drug ropinirole is safe to use in ALS patients and delayed disease progression by 27.9 weeks on average. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal motor neuron disease that causes people to gradually lose control of their muscles. There is no cure, and current treatments focus on reducing symptoms and providing supportive care. Reporting June 1 in the journal Cell Stem Cell, researchers from Japan show in an early clinical trial that the Parkinson's disease drug ropinirole is safe to use in ALS patients and delayed disease progression by 27.9 weeks on average. Some patients were more responsive to ropinirole treatment than others, and the researchers were able to predict clinical responsiveness in vitro using motor neurons derived from patient stem cells. "ALS is totally incurable, and it's a very difficult disease to treat," says senior author and physiologist Hideyuki Okano of the Keio University School of Medicine in Tokyo. "We previously identified ropinirole as a potential anti-ALS drug in vitro by iPSC drug discovery, and with this trial, we have shown that it is safe to use in ALS patients and that it potentially has some therapeutic effect, but to confirm its effectiveness we need more studies, and we are now planning a phase 3 trial for the near future." To test ropinirole's safety and effectiveness in patients with sporadic (i.e., non-familial) ALS, the team recruited 20 patients receiving care at Keio University Hospital in Japan. None of the patients carried genes predisposing to the disease, and, on average, they had been living with ALS for 20 months. The trial was double blinded for the first 24 weeks, meaning that the patients and doctors did not know which patients were receiving ropinirole and which were receiving a placebo. Then, for the following 24 weeks, all patients who wished to continue were knowingly administered ropinirole. Many patients dropped out along the way -- partially due to the COVID-19 pandemic -- so only 7/13 ropinirole-treated and 1/7 placebo-followed-by-ropinirole-treated patients were monitored for the full year. However, no patients dropped out due to safety reasons. To determine whether the drug was effective at slowing the progression of ALS, the team monitored a variety of different measures throughout the trial and for 4 weeks after treatment concluded. These included changes in the patients' self-reported physical activity and ability to eat and drink independently, activity data from wearable devices, and physician-measured changes in mobility, muscle strength, and lung function. "We found that ropinirole is safe and tolerable for ALS patients and shows therapeutic promise at helping them sustain daily activity and muscle strength," says first author Satoru Morimoto, a neurologist at the Keio University School of Medicine in Tokyo. Patients who received ropinirole during both phases of the trial were more physically active than patients in the placebo group. They also showed slower rates of decline in mobility, muscle strength, and lung function, and they were more likely to survive. The benefits of ropinirole relative to the placebo became increasingly pronounced as the trial progressed. However, placebo group patients who began taking ropinirole halfway through the trial did not experience these improvements, which suggests that ropinirole treatment may only be useful if treatment is started earlier and administered over a longer duration. Next, the researchers investigated the mechanisms behind ropinirole's effects and looked for molecular markers of the disease. To do this, they generated induced pluripotent stem cells from the patients' blood and grew these cells into motor neurons in the lab. Compared to healthy motor neurons, they found that motor neurons from ALS patients showed distinct differences in structure, gene expression, and metabolite concentrations, but ropinirole treatment reduced these differences. Specifically, motor neurons grown from ALS patients had shorter neurites compared to healthy motor neurons, but these axons grew to a more normal length when the cells were treated with ropinirole. The team also identified 29 genes related to cholesterol synthesis that tended to be upregulated in motor neurons from ALS patients, but ropinirole treatment suppressed their gene expressions over time. They also identified lipid peroxide as a good surrogate marker for estimating the effect of ropinirole both in vitro and clinically. "We found a very striking correlation between a patient's clinical response and the response of their motor neurons in vitro," says Morimoto. "Patients whose motor neurons responded robustly to ropinirole in vitro had a much slower clinical disease progression with ropinirole treatment, while suboptimal responders showed much more rapid disease progression despite taking ropinirole." The researchers say that this suggests that this method -- of growing and testing motor neurons from patient-derived induced pluripotent stem cells -- could be used clinically to predict how effective the drug would be for a given patient. It's unclear why some patients are more responsive to ropinirole than others, but the researchers think that it's probably due to genetic differences that they hope to pinpoint in future studies.
