(technology readiness)
Nine levels between scientific discovery and the global market.
The Technology Readiness Level (TRL) scale organizes a technology's maturity into nine levels, from observing fundamental principles to demonstration in an operational environment.
At Aether, this reference is applied to pharmaceutical development through an integrated approach, considering scientific evidence, technological maturity, nonclinical development, CMC, regulatory strategy, and preparation for transfer and licensing.

A common language for talking about risk, maturity, and value.
(the scale)
The TRL scale was originally developed by NASA and is now widely used as a reference for assessing the maturity of technologies in development.
In the pharmaceutical sector, its application requires contextual interpretation. An asset's progress doesn't happen in a purely linear way: scientific development, CMC, nonclinical studies, regulatory strategy, and clinical development advance in an integrated manner and can show different levels of maturity along the way.
At Aether, TRL is used as one of the axes for organizing asset progress, guiding development decisions, identifying gaps, planning evidence generation, structuring fundraising, and supporting intellectual property, technology transfer, and licensing strategies.
Each advance in maturity represents the generation of more robust evidence and the progressive reduction of scientific and technological uncertainty.
Aether uses the TRL scale as a reference for contextualized assessment of technological maturity, taking into account ISO 16290 and its application to pharmaceutical development.
(the journey)
From the bench to the market, in three development phases.
Research and Discovery
Scientific foundationsInvestigation of fundamental principles, hypothesis formulation, and generation of the first experimental evidence. The technology evolves from initial scientific knowledge to a proof of concept, with progressive assessment of its application potential.
Universities, research centers, and academic laboratories.
Translational and Preclinical Development
Validation and uncertainty reductionThe technology advances from proof of concept to increasing levels of validation, integration, and demonstration under relevant conditions. Scientific, technological, and preclinical evidence is generated, accompanied by the progressive development of CMC, regulatory strategy, and technical documentation.
Specialized laboratories, research centers, CROs, CDMOs, and technology and industrial partners.
Clinical and Operational Development
Proof and applicationThe technology reaches advanced maturity levels, generating evidence in clinical and operational settings, regulatory qualification, preparation for scale production, and, when applicable, market approval and use.
Clinical centers, CROs, the pharmaceutical industry, production units, and regulatory agencies.
(the nine levels)
The complete scale, level by level.
Click each level to see its description and a reference for its application in pharmaceutical development. The correspondence between TRL and pharmaceutical stages is contextual and may vary depending on each technology's nature and development strategy.
Exploratory scientific research, identifying and observing the fundamental principles related to the technology. Knowledge is still at an early stage of investigation.
Identification of targets, biological mechanisms, molecular classes, or candidate active ingredients; literature review and formulation of the first scientific hypotheses.
Fundamental principles begin to be translated into a potential application. Scientific and technological hypotheses are formulated and the first paths for their validation are defined.
Definition of the therapeutic concept, initial candidate selection, proposed mechanism of action, and planning of the first feasibility studies.
Initial experimental evidence demonstrates the concept's feasibility. The hypothesis is tested under controlled conditions, and the first results allow the technology's potential to be assessed.
In vitro assays, analytical studies, initial characterization, and generation of preliminary evidence of the asset's activity, mechanism, or feasibility.
The technology's main components are integrated and validated in a controlled environment. The proof of concept evolves into a more robust and reproducible configuration.
Expanded asset characterization, initial optimization, analytical development, formulation or process studies, and generation of efficacy evidence in appropriate experimental models.
The technology is evaluated under conditions that more consistently represent its intended application. Evidence generation becomes more structured and oriented toward reducing risk for subsequent stages.
Advanced preclinical studies, CMC progress, process and product characterization, stability studies, and planning of regulatory studies, according to the asset's specific strategy.
The technology is demonstrated in an integrated way under relevant conditions, with sufficient evidence to support development decisions, technology transfer, and preparation for subsequent stages.
Technically established production or synthesis process at a scale compatible with the development stage, asset characterization, generation of preclinical evidence, and technical documentation aligned with the development, transfer, and regulatory-progression strategy.
The technology reaches an advanced development stage and begins to be evaluated under use or application conditions close to its intended operational environment.
Start or advancement of clinical development, when applicable, accompanied by progress in CMC, production, quality control, and regulatory strategy.
The technology shows a high degree of maturity, with its main components qualified and robust evidence to support the final stages of development and approval.
Advanced clinical development, consolidation of the production process, industrial qualification, and preparation or submission of the evidence package required for regulatory approval, according to the therapeutic modality and applicable jurisdiction.
The technology reaches operational maturity and its application is proven in a real-world setting.
Medicine or technology in use following applicable approvals, with established production and operation, and ongoing generation of real-world safety, effectiveness, and performance evidence.
(the aether approach)
Advancing maturity while preserving the asset's strategic value.
Every advance in maturity represents both a technical evolution and a strategic decision. Generating the necessary evidence matters just as much as building, throughout development, an asset that is scientifically robust, technically transferable, and strategically positioned for partnerships and licensing.
