A novel perspective on pharmaceutical R&D costs: opportunities for reductions.

INTRODUCTION: R&D costs as an element of medicines' pricing play a prominent role in the discussions regarding the affordability of medicine. This paper investigates the details of R&D costs and the potential for reductions. AREAS COVERED: The manuscript focuses on the constitution of R&D costs in relation to medicines' pricing and its potential developments. This manuscript builds on a cost-of-opportunity approach to explore the results of potential changes in drug development and its possible economic, political, and societal impacts. EXPERT OPINION: The cost of capital is the largest cost category that could be affected by authorities. Public institutions can affect these costs by increasing public investments in R&D and reducing the amount of development time that is associated with a high capital need. In order to affect the cost of failure, it is key to understand its drivers. A government taking risks as the funder of early innovation yields an opportunity to introduce an alternative model for medicine development. Next, to control pricing, it is important to adequately reward innovation in order to ensure improved quality of care, access, and affordability of systems. Innovation, high-quality care, access, and affordability require entrepreneurial and changing positions of governments, authorities, public institutions, and the pharmaceutical industry.

A novel sustained-release cysteamine bitartrate formulation for the treatment of cystinosis: Pharmacokinetics and safety in healthy male volunteers.

The strict intake regimen of cysteamine bitartrate formulations, associated with side effects, is a concern for the treatment compliance in cystinosis therapy. Therefore, there is a need for a cysteamine formulation with an improved pharmacokinetic profile. This study investigated the pharmacokinetics, safety and tolerability of a new sustained-release cysteamine dosage form, PO-001, in healthy volunteers. This was a randomized, investigator-blinded, three-way cross-over study to compare single doses (600 mg) of PO-001 with Cystagon® (immediate-release) and Procysbi® (delayed-release). Collected blood samples were analyzed for plasma cysteamine concentrations and pharmacokinetic parameters were estimated by noncompartmental analysis. In addition, plasma cysteamine concentrations were analyzed using a population pharmacokinetic approach using NONMEM® . Pharmacokinetics showed clear sustained-release characteristics of PO-001 over time with a lower Cmax and longer Tmax compared to Cystagon® and Procysbi® . All treatment-emergent adverse events were of mild severity, with the exception of two subjects who reported moderate severity gastrointestinal problems including vomiting and diarrhea, which were related to Cystagon® intake. Population PK simulations showed a favourable PK profile based on Cmax and Ctrough concentrations at steady state. In conclusion, a single dose of 600 mg PO-001 was well tolerated with no findings of clinical concern. This new cysteamine bitartrate formulation showed pharmacokinetics of a sustained-release formulation, which may be beneficial for the treatment of cystinosis patients. This study supports advancing this type of sustained-release formulation into a subsequent study to confirm reduced dosing frequency with efficient control of white blood cells (WBCs) cystine levels.

Strategies to enable the adoption of animal biotechnology to sustainably improve global food safety and security.

The ability to generate transgenic animals has existed for over 30 years, and from those early days many predicted that the technology would have beneficial applications in agriculture. Numerous transgenic agricultural animals now exist, however to date only one product from a transgenic animal has been approved for the food chain, due in part to cumbersome regulations. Recently, new techniques such as precision breeding have emerged, which enables the introduction of desired traits without the use of transgenes. The rapidly growing human population, environmental degradation, and concerns related to zoonotic and pandemic diseases have increased pressure on the animal agriculture sector to provide a safe, secure and sustainable food supply. There is a clear need to adopt transgenic technologies as well as new methods such as gene editing and precision breeding to meet these challenges and the rising demand for animal products. To achieve this goal, cooperation, education, and communication between multiple stakeholders-including scientists, industry, farmers, governments, trade organizations, NGOs and the public-is necessary. This report is the culmination of concepts first discussed at an OECD sponsored conference and aims to identify the main barriers to the adoption of animal biotechnology, tactics for navigating those barriers, strategies to improve public perception and trust, as well as industry engagement, and actions for governments and trade organizations including the OECD to harmonize regulations and trade agreements. Specifically, the report focuses on animal biotechnologies that are intended to improve breeding and genetics and currently are not routinely used in commercial animal agriculture. We put forward recommendations on how scientists, regulators, and trade organizations can work together to ensure that the potential benefits of animal biotechnology can be realized to meet the future needs of agriculture to feed the world.
