TEDx Talks - Revolutionizing RNA therapeutics | Audrey Nsamela | TEDxIAE Aix Marseille

Audrey, a Belgian scientist and co-founder of Inside Therapeutics, emphasizes that what is often deemed impossible is merely improbable. She shares her personal story, highlighting the unlikely events that led to her existence and career, to illustrate that improbable events can and do happen. Audrey argues that impossibility is subjective, finite, and context-dependent, and can be transformed into possibility with changes in parameters or context. She uses examples like scuba diving and human flight to demonstrate how past impossibilities have become realities through innovation and persistence. In her work, Audrey focuses on RNA-based therapies, which have the potential to revolutionize treatment for cancer and genetic disorders. She explains the challenges of delivering fragile RNA molecules to target cells and how her company is innovating to overcome these barriers by developing scalable methods for drug production. Audrey encourages applying this mindset of challenging the impossible to everyday life, suggesting that by questioning and expanding the boundaries of what is considered possible, significant innovations can be achieved through incremental changes.

Key Points:

  • Impossibility is often just improbability; changing parameters can make the impossible possible.
  • Innovation thrives on challenging the impossible, as seen in historical examples like flight and scuba diving.
  • RNA-based therapies hold potential for treating cancer and genetic disorders, but face delivery challenges.
  • Audrey's company is developing scalable methods to produce RNA therapies, akin to perfecting a recipe at scale.
  • Questioning and expanding boundaries can lead to significant innovations through small, incremental changes.

Details:

1. ๐ŸŽค Meet Audrey: A Scientist on a Mission

  • Audrey is 29 years old, Belgian, and lives in Bordeaux.
  • She is the co-founder and chief scientific officer of Inside Therapeutics.
  • The company's goal is to revolutionize tools for developing new therapies for cancer, rare genetic diseases, and pandemics.
  • Audrey focuses on using innovation to overcome technological barriers.
  • She advocates for the idea that 'impossible does not exist.'

2. ๐Ÿ” Exploring the Concept of 'Impossible'

  • The speaker challenges the notion of 'impossible' by highlighting personal experiences and improbable events.
  • The probability of the speaker's parents meeting was low, considering they met in one of two dozen bars in Brussels.
  • Assuming an 8% chance, the speaker's parents started a family, illustrating the role of chance in life events.
  • The speaker's existence is the result of a unique combination of 300 million sperm cells, emphasizing the improbability of individual existence.
  • The speaker highlights the rarity of being diagnosed with a G6PD deficiency, particularly as a woman in Europe, where it is less common.
  • The cumulative probability of all these events, including the speaker becoming an engineer and co-founding a deep tech company, is described as 'almost impossible,' with a probability of 240 zeros before the first digit.

3. ๐Ÿš€ Improbable vs. Impossible: A Matter of Perspective

  • The comparison of being struck by lightning demonstrates that what is often considered impossible is merely improbable, emphasizing the need to differentiate between the two.
  • Impossibility is subjective; what is impossible for one person may not be for another, highlighting the importance of perspective in defining possibilities.
  • Impossibility is finite and context-dependent, whereas possibilities are infinite. Changing a small parameter in a situation can alter the outcome, turning the impossible into possible.
  • Examples such as technological advancements illustrate how shifts in understanding and context can transform perceived impossibilities into achievable realities.
  • The concept of improbable outcomes, like winning the lottery, showcases how low probability events can and do occur, reinforcing the infinite nature of possibilities.

4. ๐ŸŒŒ Examples of Overcoming the 'Impossible'

4.1. Scuba Diving

4.2. Jacusto's Contribution

4.3. Flight

4.4. Reevaluating Impossibility

4.5. Innovation and Impossibility

5. ๐Ÿ”ฌ Innovating in RNA Therapeutics

  • RNA therapeutics have the potential to treat cancer, infectious, or genetic disorders by either sending instructions to produce a missing or defective protein or providing tools to repair DNA mistakes.
  • The field faces significant challenges, particularly the fragility of RNA, which can be easily destroyed during delivery to target cells.
  • To address RNA's fragility, scientists developed lipid nanoparticlesโ€”tiny droplets of fatโ€”that protect RNA and release it once inside the target cells.
  • Innovations such as lipid nanoparticles have significantly improved the stability and delivery of RNA, facilitating its therapeutic potential.
  • Further research is needed to enhance delivery mechanisms and reduce potential side effects, ensuring wider application of RNA therapeutics in medicine.

6. ๐Ÿฅ„ The Art of Innovation: From Mayonnaise to Medicine

  • The process of drug development is compared to making mayonnaise, where the challenge is to replicate successful small-scale results on a larger scale.
  • The analogy highlights the importance of having the right tools ('fork') and method to ensure consistency in outcomes when scaling production.
  • A failure to reproduce results at a larger scale can lead to significant losses in time, money, and project failure.
  • The speaker's role is to create a new tool that allows seamless scaling from small to large production without compromising results.
  • Collaboration across specialties, such as vinegar (or RNA) makers and oil producers, is crucial for successful innovation.

7. ๐Ÿ”— Interrogating the Box: Redefining Possibilities

  • 250 million people are living with rare genetic diseases, and 95% lack available treatments, highlighting a significant gap in medical solutions.
  • One in five individuals is likely to develop cancer, with a survival rate of less than 20% for most, underscoring the urgency for innovative treatments.
  • RNA-based therapies hold the potential to revolutionize treatment, possibly enabling simple solutions like a single nose spray for complex diseases such as leukemia and cystic fibrosis.
  • The strategy of 'interrogating the box' involves expanding possibilities by questioning existing boundaries and focusing on incremental advancements.
  • Major innovations often stem from a series of small, strategic steps; by identifying and tackling specific limitations, seemingly impossible challenges can become solvable.
  • The advancement of RNA technology is a promising step towards a future where cancer could be eradicated, offering hope for substantial medical breakthroughs.

8. ๐Ÿค” A Call to Action: Making the Impossible Possible

  • The speaker encourages the audience to challenge boundaries and strive to achieve what seems impossible.
  • The call to action is for individuals to take initiative and push beyond their current limits.
