Linking Reimbursement to Patient Benefits for Advanced Therapy Medicinal Products and Other High-Cost Innovations: Policy Recommendations for Outcomes-Based Agreements in Europe.

OBJECTIVES: Health technology assessment (HTA) of advanced therapy medicinal products (ATMPs), such as high-cost and one-time cell and gene therapies, is particularly challenging. Outcomes-based agreements (OBAs) are a potential solution to mitigate the risks while providing access to patients but are not widely used across Europe. This study aimed to develop policy recommendations to support the acceptability and implementation of OBAs in Europe. METHODS: A policy sandbox approach was used to engage with stakeholders and explore how HTA organizations can support reimbursement decisions regarding OBAs for ATMPs. A panel of 38 experts from across the European region was convened in 2 workshops, representing payers, HTA organizations, patients, registries, and an industry trade body. RESULTS: Policy recommendations were developed to support the appropriate consideration of OBAs for reimbursing highly uncertain technologies, such as ATMPs. If a positive HTA recommendation cannot be made at the proposed price, then a simple price discount reflecting the uncertainty is preferred over complex solutions such as OBAs. If an OBA is pursued, it should be designed collaboratively with all stakeholders to understand data collection feasibility and minimize burden to patients and providers. Payers are encouraged to approach OBAs as a tool for informed decision making, including a readiness to make negative reimbursement decisions based on unfavorable evidence. CONCLUSIONS: The study presents a policy framework for using OBAs in reimbursement decisions. OBAs must be carefully designed, focusing on appropriateness and the burden of implementation. The relevant authorities should be committed to making decisions in light of the resulting evidence.

Real-World Treatment Persistence Among Advanced Therapy-Naïve or -Experienced Patients with Ulcerative Colitis Initiated on Ustekinumab or Adalimumab.

INTRODUCTION: Persistence on advanced therapies in ulcerative colitis (UC) is a useful real-world treatment performance measure. This study compared real-world persistence during the maintenance phase among advanced therapy-naïve and -experienced patients with UC initiated on ustekinumab or adalimumab. METHODS: Claims data from the IQVIA PharMetrics® Plus de-identified database (01/01/2015-06/30/2022) were used to select adult patients with UC treated with ustekinumab or adalimumab based on the agent first initiated (index date) after 10/21/2019. Inverse probability of treatment weighting was used to balance cohorts on baseline characteristics. Persistence on the index agent (no gaps in days of supply of > 120 days for ustekinumab or > 60 days for adalimumab), persistence while corticosteroid-free, while on monotherapy, and persistence on the US labeled dose were described and compared during the 12-month period post-index using Kaplan-Meier analysis and Cox proportional hazards models. Outcomes were analyzed separately among advanced therapy-naïve and advanced therapy-experienced patients. RESULTS: At 12 months post-index, advanced therapy-naïve patients receiving ustekinumab (n = 371) had higher persistence on the index agent [83.8% vs. 57.6%, hazard ratio (95% confidence interval) = 3.09 (2.29-4.16); p < 0.001), persistence while corticosteroid-free [2.00 (1.63-2.45); p < 0.001], persistence while on monotherapy [2.67 (2.07-3.44); p < 0.001], and persistence on the labeled dose [4.21 (2.76-6.44); p < 0.001] versus those receiving adalimumab (n = 1726). At 12 months post-index, advanced therapy-experienced patients receiving ustekinumab (n = 693) had higher persistence on the index agent [78.1% vs. 59.2%, 2.44 (1.82-3.26); p < 0.001], persistence while corticosteroid-free [1.24 (1.01-1.54); p = 0.0447], persistence while on monotherapy [2.53 (2.00-3.21); p < 0.001], and persistence on the labeled dose [4.77 (3.09-7.35); p < 0.001] versus those receiving adalimumab (n = 254). CONCLUSION: This claims-based analysis demonstrated significantly higher treatment persistence, including persistence while corticosteroid-free, persistence while on monotherapy, and persistence on the labeled dose, among both advanced therapy-naïve and advanced therapy-experienced patients with UC initiated on ustekinumab compared to adalimumab.

New challenges of advanced therapies. / Nuevos retos de las terapias avanzadas.

The huge development that Advanced Therapy Medicinal Products (AMTPs) have experienced in recent years, both commercial and research, represent a challenge for Hospital Pharmacy at all levels. The aim of this article is to describe the implementation of an Advanced Therapies Unit (AUT) and the process of preparation of the AMTPs according to the "good manufacturing practices" (GMP), as well as the results obtained in a tertiary hospital, as an example of the challenges posed by MTA's academic production. The AUT meets the requirements established in the GMP by guaranteeing that the medicines produced therein are of the quality required for the use for which they are intended, and also provides support to various research groups involved in the development of AMTPs. The AUT is composed of a highly qualified multidisciplinary team, qualified and trained in GMP, and is authorized for the preparation of five types of AMTPs consisting of allogeneic virus-specific T cells (VST) with various viral specificities. A circuit has been established in collaboration between the UTA and the Pharmacy Service with the Hematology Service for the assessment of the clinical indication, the request and preparation of VST, which allows the treatment of patients receiving hematopoietic stem cell transplants who present viral reactivations resistant or refractory to standard treatment, or who cannot tolerate it due to toxicity. Preliminary results from these AMTPs suggest that VSTs are an effective and safe alternative. Academic AMTPs have special interest in orphan indications or in the absence of alternative treatments, and their production through the "hospital exemption" can favor early access in the initial phases of development and at a lower cost. It is essential to promote the training of hospital pharmacists in GMP and their participation in collaboration with other clinicians and researchers to develop AMTPs that meet all logistical and regulatory requirements.

The issue of heterogeneity of MSC-based advanced therapy medicinal products-a review.

Mesenchymal stromal stem cells (MSCs) possess a remarkable potential for numerous clinical applications due to their unique properties including self-renewal, immunomodulation, paracrine actions and multilineage differentiation. However, the translation of MSC-based Advanced Therapy Medicinal Products (ATMPs) into the clinic has frequently met with inconsistent outcomes. One of the suspected reasons for this issue is the inherent and extensive variability that exists among such ATMPs, which makes the interpretation of their clinical efficacy difficult to assess, as well as to compare the results of various studies. This variability stems from numerous reasons including differences in tissue sources, donor attributes, variances in manufacturing protocols, as well as modes of administration. MSCs can be isolated from various tissues including bone marrow, umbilical cord, adipose tissue and others, each with its unique phenotypic and functional characteristics. While MSCs from different sources do share common features, they also exhibit distinct gene expression profiles and functional properites. Donor-specific factors such as age, sex, body mass index, and underlying health conditions can influence MSC phenotype, morphology, differentiation potential and function. Moreover, variations in preparation of MSC products introduces additional heterogeneity as a result of cell culture media composition, presence or absence of added growth factors, use of different serum supplements and culturing techniques. Once MSC products are formulated, storage protocols play a pivotal role in its efficacy. Factors that affect cell viability include cell concentration, delivery solution and importantly, post-thawing protocols where applicable. Ensuing, differences in administration protocols can critically affect the distribution and functionallity of administered cells. As MSC-based therapies continue to advance through numerous clinical trials, implication of strategies to reduce product heterogeneity is imperative. Central to addressing these challenges is the need for precise prediction of clinical responses, which require well-defined MSC populations and harmonized assessment of their specific functions. By addressing these issues by meaningful approaches, such as, e.g., MSC pooling, the field can overcome barriers to advance towards more consistent and effective MSC-based therapies.

Exploring Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-Associated Protein 9 (CRISPR-Cas9) as a Therapeutic Modality for Cancer: A Scoping Review.

The global burden of cancer and the limitations of conventional therapies highlight the potential of clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9 (CRISPR-Cas9) in reshaping cancer treatment paradigms. In this review, we have investigated the mechanism of CRISPR, an adaptive immune system in bacteria that enables highly precise gene editing at the molecular level. This versatile tool demonstrates its efficacy in human cancer therapy through gene knockout, metabolic disruption, base editing, screening, and immunotherapy enhancement without affecting normal bodily domains. Despite its superiority over other nucleases like zinc-finger nucleases and transcription activator-like effector nucleases, hurdles such as off-target effects, inefficient delivery of the system to target cells, the emergence of escapers, and the ethical debate surrounding genome editing are discussed. In this article, we have reviewed the promising approaches of CRISPR-Cas9 in cancer treatment while exploring the underlying mechanism, advantages, and associated challenges.

Patients' Preference on Advanced Therapy and Follow-Up Procedure for Inflammatory Bowel Disease in Japan: A Web-Based 3A Survey.

Introduction: With the recent increase in number of drugs for treating inflammatory bowel disease (IBD), it has become important to select treatments acceptable to patients. Endoscopy and biomarkers from blood and stool samples are used to evaluate IBD disease activity. This study aimed to clarify the acceptability of usage of advanced therapy and examination methods in patients through an internet-based survey. Methods: Patients with inflammatory bowel disease were asked via the internet to participate in a survey on the acceptability of nine therapies and three examination methods. The respondents rated acceptability on a scale of 1-10 and specified the most preferred option. Results: Responses were obtained from 388 patients with ulcerative colitis and 82 with Crohn's disease; 14.5% and 11.5% of the patients underwent intravenous infusions and subcutaneous injections, respectively. Once-daily oral administration had the highest acceptability score, which was significantly different from other administration usages (p < 0.0001), regardless of prior treatment history. Oral administration was preferred by 88.9% of patients. The ranking of examination methods from most to least acceptable was blood tests > endoscopy > stool tests, with significant differences among all groups (p < 0.0001). Blood testing (76%) and stool testing (4.5%) were the most and least preferred methods, respectively. Conclusions: The most acceptable usage of advanced therapy in patients with inflammatory bowel disease was once-daily oral administration. Treatments that are effective, safe, and acceptable to patients should be selected, and examination methods acceptable to patients should be used.

This article discusses the rationale for and the current data on the efficacy and safety of combined advanced targeted therapy (CATT) for the treatment of moderate-to-severe inflammatory bowel disease.

A Comprehensive Review of Emerging Therapies for Type 2 Diabetes and Their Cardiovascular Effects.

The discovery of inhibitors for sodium-glucose cotransporter 2 (SGLT2) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) has significantly improved type 2 diabetes management. Large-scale clinical studies have shown that both SGLT2 inhibitors and GLP-1 RA enhance cardiovascular health. Benefits include reduced cardiovascular disease risk, lower mortality, fewer heart failure hospitalizations (SGLT2 inhibitors), and stroke prevention (GLP-1 RA). Additionally, these drugs slow chronic kidney disease progression. This comprehensive treatment targets vascular events. Despite differences, both drug classes are crucial. GLP-1 RA mainly reduce stroke risk, while SGLT2 inhibitors alleviate heart failure. Our findings, based on a literature review, will address the renal and cardiac effects of SGLT2 inhibitors and GLP-1 RA in both diabetics and non-diabetics, highlighting their combined benefits for heart conditions.

Comparison of real-world healthcare resource utilization among advanced therapy-naïve and advanced therapy-experienced patients with ulcerative colitis initiated on ustekinumab or vedolizumab.

OBJECTIVES: To describe and compare healthcare resource utilization (HRU) among advanced therapy-naïve and advanced therapy-experienced patients with ulcerative colitis (UC) initiating ustekinumab or vedolizumab in the United States. METHODS: Claims data from IQVIA PharMetrics Plus de-identified database (01/01/2015-06/30/2022) were used to identify adult patients with UC initiating ustekinumab or vedolizumab (index date) after 10/21/2019. Baseline characteristics were balanced using inverse probability of treatment weighting. All-cause and UC-related HRU (number of inpatient admissions, inpatient days, emergency department visits, and outpatient visits) were described during the post-index period, and Poisson regression models were used to evaluate associations between index therapy and HRU outcomes. Analyses were performed separately among advanced therapy-naïve or advanced therapy-experienced patients. RESULTS: A total of 444 (ustekinumab) and 1,917 (vedolizumab) advanced therapy-naïve patients, and 647 (ustekinumab) and 1,152 (vedolizumab) advanced therapy-experienced patients were identified. In advanced therapy-naïve patients, higher rates of UC-related inpatient days (rate ratio [95% confidence interval] = 1.84 [1.15, 3.58]; p = 0.004), emergency department visits (1.39 [1.01, 2.17]; p = 0.044), and outpatient visits (1.81 [1.61, 2.04]; p < 0.001) were observed among patients initiating vedolizumab relative to ustekinumab. In advanced therapy-experienced patients, higher rates of UC-related inpatient admissions (1.47 [1.06, 2.12]; p = 0.012), inpatient days (2.18 (1.44, 3.71); p < 0.001), and outpatient visits (1.50 (1.19, 1.82); p < 0.001) were observed among patients initiating vedolizumab relative to ustekinumab. Results were similar when all-cause HRU was examined. CONCLUSIONS: Among patients with UC with and without advanced therapy experience, higher rates of all-cause and UC-related HRU were observed among those treated with vedolizumab relative to ustekinumab.

Successful transport across continents of GMP-manufactured and cryopreserved culture-expanded human fetal liver-derived mesenchymal stem cells for use in a clinical trial.

Introduction: Cell therapy has been increasingly considered to treat diseases, but it has been proven difficult to manufacture the same product at multiple manufacturing sites. Thus, for a wider implementation an alternative is to have one manufacturing site with a wide distribution to clinical sites. To ensure administration of a good quality cell therapy product with maintained functional characteristics, several obstacles must be overcome, which includes for example transfer of knowledge, protocols and procedures, site assessment, transportation and preparation of the product. Methods: As the preparatory work for a clinical trial in India using fetal mesenchymal stem cells (fMSCs) developed and manufactured in Sweden, we performed a site assessment of the receiving clinical site, transferred methods, developed procedures and provided training of operators for handling of the cell therapy product. We further developed a Pharmacy Manual to cover the management of the product, from ordering it from the manufacturer, through transport, reconstitution, testing and administration at the clinical site. Lastly, the effect of long-distance transport on survival and function of, as well as the correct handling of the cell therapy product, was evaluated according to the pre-determined and approved Product Specification. Results: Four batches of cryopreserved human fetal liver-derived fMSCs manufactured according to Good Manufacturing Practice and tested according to predetermined release criteria in Sweden, were certified and transported in a dry shipper at -150 °C to the clinical site in India. The transport was temperature monitored and took three-seven days to complete. The thawed and reconstituted cells showed more than 80% viability up to 3 h post-thawing, the cell recovery was more than 94%, the cells displayed the same surface protein expression pattern, differentiated into bone, had stable chromosomes and were sterile, which conformed with the data from the manufacturing site in Sweden. Conclusions: Our study shows the feasibility of transferring necessary knowledge and technology to be able to carry out a clinical trial with a cell therapy product in distant country. It also shows that it is possible to transport a cryopreserved cell therapy product over long distances and borders with retained quality. This extends the use of cryopreserved cell therapy products in the future.

Treatment patterns for patients with BRCA1/2-positive metastatic castration-resistant prostate cancer.

BACKGROUND: Patients with BRCA-positive metastatic castration-resistant prostate cancer (mCRPC) have an aggressive disease course. This study aimed to describe real-world treatment patterns among patients with BRCA-positive mCRPC. MATERIALS AND METHODS: De-identified electronic health record data from the Flatiron Health-Foundation Medicine Inc. Metastatic Prostate Cancer Clinico-Genomic Database (January 01, 2011 to June 30, 2022) were used to select patients with BRCA-positive mCRPC initiating first-line (1L) therapy with an oncologist-defined advanced line of therapy (LOT) or androgen deprivation therapy (ADT) monotherapy. Treatment sequences and reasons for censoring were described in 1L, and among patients who initiated a second-line (2L) therapy. RESULTS: A total of 98 treated patients with BRCA-positive mCRPC were identified. The top 3 treatment regimens in 1L, overall, were ADT monotherapy (19%), enzalutamide (14%), and olaparib (13%). The main reason for censoring patients with ADT monotherapy was death (52.6%). Among 79 patients treated with an advanced LOT in 1L, 43.0% (n = 34) did not initiate a 2L therapy, of which, 29.4% died. In patients who initiated a 2L (n = 45), the most common 1L to 2L treatment sequence was olaparib to docetaxel (11.1%). The most prescribed 2L therapies were docetaxel (22.2%), olaparib (20.0%), abiraterone acetate (13.3%), and enzalutamide (11.1%). From 1L initiation, the median time-to-next-treatment was 6.2 months. CONCLUSION: Among patients with BRCA-positive mCRPC, ADT monotherapy, enzalutamide, and olaparib were most commonly used. Prognosis of BRCA-positive patients was poor, with most patients failing initial therapy resulting in a switch to a new therapy or death. These findings highlight the need for earlier and more effective treatments for patients with BRCA-positive mCRPC.

Advanced Therapies for Human Immunodeficiency Virus.

Human Immunodeficiency Virus (HIV) remains a significant global health challenge with approximately 38 million people currently having the virus worldwide. Despite advances in treatment development, the virus persists in the human population and still leads to new infections. The virus has a powerful ability to mutate and hide from the human immune system in reservoirs of the body. Current standard treatment with antiretroviral therapy effectively controls viral replication but requires lifelong adherence and does not eradicate the virus. This review explores the potential of Advanced Therapy Medicinal Products as novel therapeutic approaches to HIV, including cell therapy, immunisation strategies and gene therapy. Cell therapy, particularly chimeric antigen receptor T cell therapy, shows promise in preclinical studies for targeting and eliminating HIV-infected cells. Immunisation therapies, such as broadly neutralising antibodies are being investigated to control viral replication and reduce reservoirs. Despite setbacks in recent trials, vaccines remain a promising avenue for HIV therapy development. Gene therapy using technologies like CRISPR/Cas9 aims to modify cells to resist HIV infection or eliminate infected cells. Challenges such as off-target effects, delivery efficiency and ethical considerations persist in gene therapy for HIV. Future directions require further research to assess the safety and efficacy of emerging therapies in clinical trials. Combined approaches may be necessary to achieve complete elimination of the HIV reservoir. Overall, advanced therapies offer new hope for advancing HIV treatment and moving closer to a cure.

Early psoriatic arthritis: when is the right time to start advanced therapy?

Despite significant advances in the treatment of psoriatic arthritis (PsA) in the last two decades, remission remains elusive and there is no cure. Evidence from rheumatoid arthritis (RA) confirming enhanced response and outcome from earlier treatment intervention suggests the plausibility of the window of opportunity in the pathogenesis of RA. Yet, data are lacking in PsA. Although treatment response may be enhanced in shorter disease duration, it is unknown how this early intervention may impact long-term outcomes. Furthermore, it remains to be demonstrated whether there is a best treatment strategy and time of intervention. Crucially, the main hurdle when aiming for early treatment intervention is the ability to achieve a timely diagnosis that highlights the need to focus research efforts on characterizing the very early disease stages including the transition to PsA in the at-risk psoriasis population.

This chapter describes an optimized upstream protocol for laboratory-scale MSC production from different tissue sources. This protocol, conducted in flasks, controls critical parameters and lays the foundation for downstream processing to generate ATMPs. This comprehensive approach underscores the potential of MSCs in clinical applications and the importance of tailored production processes.

Mesenchymal Stromal Cell-Based Products: Challenges and Clinical Therapeutic Options.

Mesenchymal stromal cell (MSC)-based advanced therapy medicinal products (ATMPs) are being tried in a vast range of clinical applications. These cells can be isolated from different donor tissues by using several methods, or they can even be derived from induced pluripotent stem cells or embryonic stem cells. However, ATMP heterogeneity may impact product identity and potency, and, consequently, clinical trial outcomes. In this review, we discuss these topics and the need to establish minimal criteria regarding the manufacturing of MSCs so that these innovative therapeutics may be better positioned to contribute to the advancement of regenerative medicine.

Benefits of Biosimilars in the Management of Patients with Inflammatory Bowel Disease: An International Survey.

Background/Objectives: The development of biosimilar drugs has revolutionized the management of patients with inflammatory bowel diseases (IBD), significantly reducing healthcare costs. However, the impact of biosimilar availability on patient care is unknown. We conducted a survey to investigate the benefits of using biosimilars in patients with IBD. Methods: Physicians involved in the IBD care were invited to participate in an anonymous online survey. The questionnaire consisted of 42 questions addressing availability, cost, recommendations, and positioning regarding the use of biosimilars. Results: A total of 233 physicians (88.4% gastroenterologists) from 63 countries worldwide participated in the survey. Most respondents had >10 years of practice (202/233, 85.9%). Biosimilars were available in almost all cases (221, 94.8%), and over two-thirds of respondents had more than one biosimilar of adalimumab or infliximab on hospital formulary. In most cases, adalimumab and infliximab biosimilars had a reduced cost of at least 30% compared to the originators. The savings resulting from the use of biosimilars allowed physicians to improve patient care (3/233, 1.3%) or to improve research (2/233, 0.8%) in only a few cases. Interestingly, for about 50% of respondents, the cost of biologics was a limitation for patient access to therapy. For the majority of participants, the availability of biosimilars did not influence treatment decisions in Crohn's disease (70/165, 42.4%) and ulcerative colitis (83/165, 50.3%). Conclusions: The reduced cost of biosimilars compared to reference products is the main driver of choice in IBD. The impact of biosimilars of ustekinumab and vedolizumab in improving access to therapies and changing the treatment algorithm remains to be defined.

The evolving regulatory system of advanced therapy medicinal products in China: a documentary analysis using the World Health Organization Global Benchmarking Tool standards.

Advanced therapy medicinal products (ATMPs) are rapidly evolving to offer new treatment options. The scientific, technical, and clinical complexities subject drug regulatory authorizes to regulatory challenges. To advance the regulatory capacity for ATMPs, the National Medical Products Administration in China made changes to the drug regulatory system and developed regulatory science with the goal of addressing patient needs and encouraging innovation. This study aimed to systematically identify the regulatory evidence on ATMPs in China under the guidance of an overarching framework from the World Health Organization Global Benchmarking Tool. It was found that China's administrative authorities at all levels have issued a number of policy documents to promote the development of ATMPs, covering biopharmaceutical products research and development (n = 14), biopharmaceutical industry development (n = 9), high-quality development of medical institutions (n = 1), specific development plans/projects (n = 6) and specific regional development (n = 4). The legal and regulatory framework of ATMPs in China has been established and is subject to continuous adjustment in various aspects including regulations (n = 3), departmental rules or administrative normative documents (n = 22), and technical guidance (n = 15). As the regulatory reform continues, the drug review processes have been revised, and various technical standards have been launched, which aim to establish a regulatory approach that oversees the full life-cycle development of ATMPs in the country. The limited number of investigational new drug applications and approved ATMPs suggests a lag remains between the translation of advanced therapeutic technologies into clinically available medical products. To accelerate the translational research of ATMP in countries such as China, developing and adopting real-world evidence generated from clinical use in designated healthcare facilities to support scientific decision-making in ATMP regulation is warranted. The enhancement of regulatory capacity building and multi-stakeholder collaborations should also be encouraged to facilitate the timely evaluation of promising ATMPs to meet more patient needs.

Ozanimod in Patients With Moderate to Severe Ulcerative Colitis Naive to Advanced Therapies.

BACKGROUND & AIMS: The pivotal phase 3 True North (TN) study demonstrated the efficacy and safety of ozanimod in patients with moderately to severely active ulcerative colitis. This analysis assessed ozanimod during TN and the ongoing open-label extension (OLE) in patients with active disease who were naive to advanced therapies (ATs). METHODS: TN was a randomized, double-blind, placebo-controlled trial consisting of 10-week induction period and 42-week maintenance period. Eligible patients could enter the OLE. Symptomatic efficacy was evaluated from induction through the OLE. Clinical, endoscopic, and mucosal outcomes were evaluated at the end of induction (Week [W] 10) and maintenance (W52) and at predefined OLE timepoints (OLE W46 and W94). Safety during TN was reported. RESULTS: This analysis included 616 AT-naive patients. Numerically greater proportions of patients receiving ozanimod than placebo achieved symptomatic response (39% vs 29%, 95% confidence interval, -0.1 to 18.8) by W2, with significant differences (56% vs 39%, 95% confidence interval, 6.3-26.3) achieved by W4. Patients receiving ozanimod showed significant improvements across efficacy outcomes versus placebo at W10 and W52 (P < .05, all endpoints). In patients on continuous ozanimod who entered the OLE in clinical response at W52, 91% maintained clinical response through OLE W94, and 74% achieved endoscopic improvement and 57% achieved mucosal healing at OLE W94. In ozanimod-treated patients without clinical response by W10 who received extended induction in the OLE, 62% achieved symptomatic response by OLE W10. Safety outcomes in AT-naive patients were consistent with the total TN population. CONCLUSIONS: Ozanimod is an effective, durable, and well-tolerated oral therapy for AT-naive ulcerative colitis patients. CLINICALTRIALS: gov, numbers NCT02435992 and NCT02531126.

Translational Approach Using Advanced Therapy Medicinal Products for Huntington's Disease.

Current therapeutic approaches for Huntington's disease (HD) focus on symptomatic treatment. Therefore, the unavailability of efficient disease-modifying medicines is a significant challenge. Regarding the molecular etiology, targeting the mutant gene or advanced translational steps could be considered promising strategies. The evidence in gene therapy suggests various molecular techniques, including knocking down mHTT expression using antisense oligonucleotides and small interfering RNAs and gene editing with zinc finger proteins and CRISPR-Cas9-based techniques. Several post-transcriptional and post-translational modifications have also been proposed. However, the efficacy and long-term side effects of these modalities have yet to be verified. Currently, cell therapy can be employed in combination with conventional treatment and could be used for HD in which the structural and functional restoration of degenerated neurons can occur. Several animal models have been established recently to develop cell-based therapies using renewable cell sources such as embryonic stem cells, induced pluripotent stem cells, mesenchymal stromal cells, and neural stem cells. These models face numerous challenges in translation into clinics. Nevertheless, investigations in Advanced Therapy Medicinal Products (ATMPs) open a promising window for HD research and their clinical application. In this study, the ATMPs entry pathway in HD management was highlighted, and their advantages and disadvantages were discussed.
