Roadmap Overview

mRNA vaccines represent a breakthrough in immunization technology, offering a novel approach compared to traditional vaccines. Unlike conventional vaccines, which often use weakened or inactive forms of a virus to trigger an immune response, mRNA vaccines work by instructing cells in the body to produce a protein that is part of the virus, leading to an immune response without ever exposing the body to the actual virus. This method allows for quicker development and adaptation, which is particularly advantageous during a rapidly evolving pandemic. The technology's agility enables it to be reprogrammed against new viral strains, providing a significant benefit over traditional vaccines that require longer development times for each new variant.
This roadmap gives a structured overview of the mRNA vaccine technology, breaking down each phase into specific processes and tasks. Each step is crucial to ensuring the safety, efficacy, and availability of the vaccine to the masses.

Roadmap Model using OPM

Discovery

The discovery process spans from obtaining the genetic information of the target virus to the phase just before the commencement of human clinical trials.

Development

The development process begins with the first human clinical trial and continues until the drug receives approval.

Manufacturing process

The manufacturing process begins after the drug has been approved. It starts with the assembly of each ingredient component and continues through to the shipment of the finished vaccine products.

Actual Vaccination Situation

The Actual Vaccination Situation refers to the process that starts with receiving the vaccine products at the vaccination site and culminates in individuals gaining immunity after being administered the vaccines.

Figures of Merit

A Figure of Merit has been established as follows.

1. Development period for the novel pathogen: Discovery, Development, and Manufacturing:
These stages represent the timeline of vaccine production, from initial research (discovery), through clinical trials and refinement (development), and finally to large-scale vaccine production (manufacturing). Measuring these in days indicates an emphasis on rapid response capabilities.

2. Time required to respond to mutations: Discovery, Development, and Manufacturing:
Measures how quickly a vaccine can respond to pathogen mutations, as well as development time. The ability to rapidly modify a vaccine in the face of evolving threats is essential to maintaining vaccine efficacy. Efficacy.

3. Efficacy: Prevent disease/Prevent severity:
This measures a vaccine's effectiveness in preventing disease and its severe consequences in different age groups (children, the elderly, or so on). Percentages indicate the percentage of vaccinated individuals for whom the vaccine effectively prevents disease and severe consequences in each category.

4. Safety: Mild Side Effects/Severe Side Effects:
This aspect assesses the safety profile of a vaccine across different age groups by measuring the incidence of side effects classified as mild or severe. Percentages indicate the percentage of recipients who experienced adverse reactions.

5. Recommended storage temperature
This indicator is critical to the logistic plan as it indicates the temperature range that maintains the stability and efficacy of the vaccine.

6. Ease of injection
This refers to the method of administration (e.g., intramuscular injection or nasal drip) and its convenience. It includes factors such as patient comfort, ease of administration in different settings, and training required for healthcare professionals.

By encompassing these categories, the FOM provides a comprehensive framework for vaccine evaluation. This is especially important for emerging pathogens for which rapid development, adaptability, and effective distribution are key. It also takes into account demographic responses, which are critical for coordinating public health strategies.

Vaccine Innovations

Below is a history of vaccination innovations. While we don't have vaccines for certain diseases, the chart highlights the year in which the causative agent was linked to the disease and the year the vaccine received licensing in the US for various diseases.

A timeline of innovation in the development of vaccines(Source:https://ourworldindata.org/vaccination)

Based on the graph above, we have constructed the table below. This table indicates the duration taken for vaccine development. For the years, we've calculated the midpoint between the year the causative agent was linked to the disease and the year the vaccine received licensing in the US.

From the table above, we created the graph below.

In the realm of vaccine development, different vaccines target various pathogens or conditions. It's not accurate to assume that technological advancements will necessarily shorten the development timeframe. A significant portion of the development process is the clinical trial phase, which has become lengthier in recent times. This is due to heightened awareness and stricter requirements for drug safety. Therefore, when assessing technological advancements in this field, we must also consider other Figures of Merit (FOMs) such as the drug's effectiveness and safety profile. However, even taking these into account, progress in drug development isn't always straightforward. External influences, like regulatory standards for medicines and the inherent challenges of targeting diverse diseases, can introduce significant variability in development timelines.

Vaccine Development for Coronaviruses

Next, we focused our analysis on the FOM by examining solely the vaccine development for coronaviruses. Specifically, we compared the vaccine development processes for SARS, MERS, and COVID-19(SARS-CoV-2).

COVID-19

Milestones and events leading to the successful development of COVID-19 vaccines(Source:Bok, K., Sitar, S., Graham, B. S., & Mascola, J. R. (2021). Accelerated COVID-19 vaccine development: milestones, lessons, and prospects. Immunity, 54(8), 1636-1651. )

Discovery: Jan 11, 2020: nCov sequence released. Jan 14: VRC and Moderna Collaborate on COVID-19 vaccine design. Mar 16: 1st Phase 1 trial of USG-supported COVID-19 vaccine begins enrolling (Moderna mRNA).
Development: Nov 16, Moderna announces results of interim analysis from phase 3 study

SARS

SARS was recognized as an emerging infectious disease in March 2003.
DNA vaccine: the study from December 13, 2004 through May 2, 2005
Inactivated SARS-CoV vaccine: May to October 2004, 36 healthy people from the Beijing metropolitan area were enrolled into aPhase I clinical trial

MERS

MERS was recognized as an emerging infectious disease in September 2012.Only three potential MERS-CoV vaccine candidates have progressed to phase I clinical trials: a DNA vaccine (GLS-5300) and two viral vector-based vaccines (MVA-MERS-S and MERS001).
GLS-5300: Study Start (Actual) 2016-02.GLS-5300 is a DNA plasmid vaccine that expresses the MERS CoV spike (S) glycoprotein
MVA-MERS-S: Study Start (Actual) 2017-11-28. The vaccine contains a Modified Vaccinia Virus Ankara (MVA) vector expressing the MERS-CoV spike glycoprotein (S).
MERS001: Study Start (Actual) 2018-03-14

According to the figure above, we created the graph below.

Firstly, the COVID-19 vaccines represent the only successfully developed vaccines against coronaviruses. Their accelerated development can be attributed to prior experiences with SARS and MERS. Interestingly, the development period for the MERS vaccine was longer than that for SARS, and we aim to investigate the reasons behind this extended timeline. One potential explanation could be the challenges associated with the MERS immunological response. The rapid development of COVID-19 vaccines is linked to the research history of SARS and MERS. As illustrated in the figure below, there is a significant similarity among SARS-CoV, MERS-CoV, and SARS-CoV-2. This similarity enabled the developers of the SARS-CoV-2 vaccines to quickly identify the sequence that produces the S protein, which is the primary target of the vaccines.

Alignment with Company Strategic Drivers

Number	Strategic Drivers	Alignment targets
1	To develop an mRNA vaccine platform that can flexibly address various diseases simply by reconfiguring the nucleotide sequence of mRNA, thereby enhancing manufacturing efficiency in terms of development duration and cost	This roadmap aims for a development period of 300 days or less for any novel pathogen. This driver is currently aligned with the 2MRV technology roadmap
2	To make the technical conditions required during transportation easier in order to enable the delivery of the vaccine to a broader range of regions	This roadmap aims for a recommended storage temperature of 25°C (room temperature). This driver is currently aligned with the 2MRV technology roadmap
3	To extend the duration of vaccine efficacy to gain a competitive edge in the market, while considering the balance between re-vaccination frequency and long-term revenue	This roadmap aims for higher efficacy, but does not set a target for duration of efficacy. This driver is not partially aligned with 2MRV. Also, a longer duration of efficacy may reduce the need for re-vaccination, potentially decreasing long-term revenue opportunities.

Positioning of Company vs. Competition

The COVID-19 vaccines being promoted by Pfizer/BioNTech and Moderna are mRNA vaccines. These two companies' vaccines maintain superiority in terms of efficacy compared to others. However, from the perspective of the cold chain, the mRNA vaccines require maintaining a required temperature for maximum shelf life at -70°C and -20°C. This aspect is a challenge for improvement in mRNA vaccines. The cold chain refers to a logistics system that maintains a constant low-temperature state from the time a product is manufactured until it reaches the final consumer. It is especially important for maintaining the quality of temperature-sensitive products such as pharmaceuticals and food. In the case of mRNA vaccines, maintaining their stability requires transportation and storage at extremely low temperatures.

T = Vaccine type (mRNA = -45, non-mRNA = 5) + (only for mRNA) Solid (+50)

The model is highly sensitive to both the vaccine type and the state. Both parameters have an equal impact on the temperature, changing it by 50°C. To visualize this, a tornado chart would have two bars of equal length, one for the vaccine type and one for the state.

As another FOM, we would like to choose efficacy.

Efficacy = β0 + β1 × mRNA

Here, β0(Intercept) = 74.4
β1 (Coefficient for mRNA) = 18.1

The formulated model proficiently predicts the optimal temperature to maximize the shelf life of most vaccines. However, discrepancies are observed for Pfizer/BioNTech and Moderna vaccines in their liquid states. The model's sensitivity is notably influenced by the vaccine type and its state.

Regarding efficacy, the incorporation of mRNA appears to enhance vaccine efficacy. Yet, this comes at the cost of reduced temperature stability, presenting a trade-off scenario.

The depth of this analysis is somewhat constrained due to limited data availability. With more extensive data, the model's precision could be significantly improved.

It's crucial to acknowledge the inherent differences across disciplines. For instance, while analytical formulas can be readily developed in fields like aerospace or mechanics, the realm of chemistry and biology operates differently. The governing equation in these domains is the Schrödinger wave equation, which is inherently probabilistic and lacks a definitive analytical solution. Therefore, while formulating models to optimize processes can be beneficial, one must be cognizant of the inherent limitations, especially in the bio-pharma sector.

First The research by Karikó et al. delves into the role of Toll-like receptors (TLRs) in recognizing RNA molecules and how modifications in RNA nucleosides can impact this recognition. TLRs are a type of protein that plays a crucial role in the innate immune system by detecting foreign molecules, including microbial pathogens. When activated, TLRs can initiate a host's response to infections, triggering potent innate immune responses that lead to subsequent adaptive immune responses.

In the context of vaccine development:

Adjuvants and Vaccine Potency: TLRs are being explored as targets for the development of vaccine adjuvants. Adjuvants are substances added to vaccines to enhance the body's immune response to the vaccine. TLR agonists, which are molecules that can activate TLRs, have been formulated in licensed vaccines to boost their efficacy. For instance, TLR agonists like monophosphoryl lipid A (MPL) and CpG-1018 are used in licensed vaccines for their adjuvant activity. Reference: Jing-Xing Yang, Jen-Chih Tseng, Guann-Yi Yu, Yunping Luo, Chi-Ying F. Huang, Yi-Ren Hong, Tsung-Hsien Chuang. "Recent Advances in the Development of Toll-like Receptor Agonist-Based Vaccine Adjuvants for Infectious Diseases".

Cancer Immunotherapy: Beyond infectious diseases, TLRs are also being explored in the realm of cancer immunotherapy. The activation of TLRs can promote both innate inflammatory responses and the induction of adaptive immunity, making them potential targets for cancer treatment. Some research has focused on developing nanoparticles that can selectively target endosomal TLRs to potentiate robust cancer vaccination. Reference: Heming Xia, Mengmeng Qin, Zenghui Wang, Yaoqi Wang, Binlong Chen, Fangjie Wan, Mingmei Tang, Xingquan Pan, Ye Yang, Jianxiong Liu, Ruiyang Zhao, Qiang Zhang, Yiguang Wang. "A pH-/Enzyme-Responsive Nanoparticle Selectively Targets Endosomal Toll-like Receptors to Potentiate Robust Cancer Vaccination".

Selective Immune Response: The study by Karikó et al. suggests that the innate immune system might detect unmodified RNA to selectively respond to bacterial infections or necrotic tissue. This selective response can be harnessed to develop vaccines that elicit a targeted immune reaction against specific pathogens.

In summary, the understanding of TLRs, their activation by RNA, and the impact of nucleoside modifications can provide valuable insights for the development of more effective vaccines and immunotherapies. The work by Karikó and others in this field lays the foundation for innovations in vaccine design and the broader field of immunology.

Publications

Reichmuth, Andreas M., et al. "mRNA vaccine delivery using lipid nanoparticles." Therapeutic delivery 7.5 (2016): 319-334.

Abstract: Messenger RNA (mRNA) vaccines have the potential to rapidly combat infectious diseases and cancer by delivering one or multiple mRNA molecules that encode disease-specific antigens into cells. Once inside the cells, the mRNA is translated into protein and the specific antigen is presented to the immune system. Lipid nanoparticles (LNPs) are the leading systems for the delivery of mRNA vaccines due to their ability to encapsulate and protect the mRNA from degradation, and facilitate its delivery into cells. This article reviews the composition, physicochemical properties, biocompatibility, and the efficacy of LNPs for mRNA delivery. It also discusses the challenges and future prospects of using LNPs for mRNA vaccine delivery.

Relationship to mRNA Vaccine Development: The article discusses the potential of mRNA vaccines in combating infectious diseases and cancer. mRNA vaccines work by introducing a piece of mRNA into the body, which instructs cells to produce a protein that triggers an immune response. This immune response can then protect against future infections or diseases.

However, delivering mRNA into cells is challenging because mRNA is unstable and can be easily degraded. This is where lipid nanoparticles (LNPs) come into play. LNPs can encapsulate the mRNA, protecting it from degradation, and help in delivering it into cells where it can be translated into the target protein.

The article reviews the properties of LNPs, such as their composition, physical and chemical properties, and their biocompatibility. It emphasizes that LNPs are the leading delivery systems for mRNA vaccines, highlighting their efficacy in delivering mRNA into cells.

In the context of recent developments, LNPs have been crucial in the successful development and deployment of mRNA-based COVID-19 vaccines, such as those developed by Pfizer-BioNTech and Moderna. These vaccines use LNPs to deliver the mRNA encoding the spike protein of the SARS-CoV-2 virus, triggering an immune response against the virus.

In summary, the article underscores the importance of LNPs in the development of mRNA vaccines, detailing their role in ensuring the stability and efficient delivery of mRNA into cells, which is pivotal for the vaccine's effectiveness.

The inhalable vaccine represents a leap forward in improving administration and efficacy, offering a more user-friendly and potentially more effective alternative.

Lastly, our development of Freeze-Drying Technology for mRNA Vaccines is a critical component of our strategy. This technology is poised to revolutionize the distribution of vaccines, especially in low- and middle-income countries (LMICs), by significantly reducing the reliance on cold chain logistics. This advancement will facilitate wider distribution and ensure that vaccines remain stable and effective, even in challenging environments.

Together, these initiatives form the cornerstone of our technology strategy, representing a comprehensive approach to overcoming current barriers in vaccine distribution and administration. Our strategy is visualized in a “swoosh” chart, which illustrates the dynamic progression of these projects from conception through development, growth, and eventual widespread implementation. This chart symbolizes our journey towards creating more accessible, efficient, and effective vaccine solutions for the world.

Adaptive R&D Strategy: Recognizing the variability of financial landscapes, we have a flexible R&D plan. While our optimal scenario involves parallel development of all three projects, we can adapt to more linear progression if financial constraints arise. In this model, we would sequentially initiate each project, with each one's revenue funding the next. This staged approach ensures financial viability and continuous innovation, even in fluctuating economic conditions.
