Adam Freund (CEO) and Remi Laberge (CTO) are the founders of Arda Therapeutics, a biotechnology company developing novel therapies that selectively eliminate harmful cell populations driving chronic diseases. In this episode, they discuss their innovative approach to treating conditions like idiopathic pulmonary fibrosis by identifying and removing specific cell types that cause tissue damage, rather than trying to modify cellular behavior through traditional drug approaches.
The Finer Details:
The concept of pathogenic cells as drivers of chronic diseaseHow single-cell RNA sequencing enables precise identification of harmful cell populationsArda's approach to developing targeted antibody therapeuticsAdvantages of cell elimination versus pathway modificationThe potential for intermittent dosing to improve patient quality of lifeFuture applications in aging and age-related diseasesQuotes:
"Cells make up tissues. Tissues make up organisms... If you have the right cell at the right place, everything looks good. If you have the wrong cell at the wrong place, doing the wrong thing, the tissue will decay."
"We position our strategy as an alternative to traditional pathway targeting... changing cell behavior by blocking a single node could be quite challenging."
"This is game changer for the patient experience. If we're successful, our drug will be administered once a quarter, once every six months. But during that time, this patient feels like he is not a patient. He doesn't take a drug, he's not under treatment, and doesn't have the side effect of taking those drugs."
"We think that cell depletion is a broadly applicable strategy across many chronic diseases, including potentially aging itself one day."
"In 10 years from now... we will know precisely which cells to eliminate. Now, will we be allowed to do it in an otherwise healthy patient? That's a different type of question."

Quotes have been lightly edited for clarity.
"In the past, I've heard people refer to the DNA as the blueprint of biology, and I don't quite like that analogy. I think of it as more like the hardware, and the epigenome is the source code â the epigenome is responsible for the complex coordination of different genes that lead to proteins, and the temporal aspects of those so it's really how the hardware is used to make and maintain and change different cell types."
"We're opening up the epigenome as a platform for drug discovery. The vast majority of the genome is not the coding regions, but it's incredibly important in controlling gene expression. So there's a lot of biology in there to inform our selection of targets, and we think that could dramatically improve both the number of interesting targets and our ability to select targets. The data that we're creating, our expertise, and our computational tools make us amongst the best in the world at using the epigenome for drug discovery."

Hans Keirstead, PhD, is the Chairman of the Board at Immunis, a biotechnology company researching and developing immune secretome products to address age-driven immune deficits. In this episode, Chris and Hans discuss Immunis' approach to targeting the aging immune system as a key driver of age-related disease. They explore the potential of immune secretome factors to restore youthful immune function, the promising results from Immunis' preclinical and early clinical studies, and the future of immune-modulating therapeutics to extend healthspan.
THE FINER DETAILS
The critical role of the immune system in the aging process and age-related diseaseImmunis' focus on immune precursor cell secretome factors to restore youthful immune functionPreclinical studies demonstrating the effects of Immunis' secretome product on muscle growth, metabolism, and inflammation in aged miceEarly results from Immunis' Phase 1/2a clinical trial in older adults with muscle atrophy and knee osteoarthritisThe potential for immune secretome therapeutics to treat a wide range of age-related conditions and enhance healthspanThe importance of developing affordable and accessible therapies to maximize impactQUOTES
"Every manifestation of aging is immunologically mediated. It's phenomenal. When one ages, your immune system in 100% of humans gets angry, so becomes highly pro-inflammatory.""Our drug is not a stem cell. It's not an immune cell. It is the secretion set, that same secretion set that you and I have, and everyone on this earth has, that precipitously declines with age, and now we're able to restore it.""We showed that IMMUNA fundamentally changes gene expression in order to promote the expression of genes for growth and regeneration. And then it inhibits the expression of genes that inhibit growth and regeneration.""I believe that this [secretome therapeutic] is going to be taken prophylactically by most humans, every quarter or so, to keep their immune system young, keep their immune system in a prophylactically competent state.""I want this thing to be available to everyone who wants it at an extremely low price, so that we can keep people alive, so that we can keep them disease free, so they can have productive years in their golden times, in their older age."LINK TO PAPER

Quotes have been lightly edited for clarity.
"Obviously, we look at our skin from the lens of aesthetics or of beauty. But our skin is our largest organ, and its main function is to protect our whole body against pathogens and different types of environmental stressors. As the skin ages and deteriorates, the function also gets compromised."
âThat's one of the things that we're interested in and exploring at OneSkin: not only how to improve your appearance, but also how to improve your skin function so it can aid in your overall health.â
"We realized none of the products out there were developed with the rationale of targeting aging itself."
"When we treat dermal fibroblasts with this peptide, we could decrease the amount of senescent cells by 40â50%."
"More and more, the population is getting educated. They don't want just marketing claims, they want to understand and trust brands that can really bring proof."
"People are more open to say, okay, if I need to put something on my skin, I should use a company that's actually doing real science."
"Our primary goal is to continue to be the most innovative company when it comes to skin aging, and to continue to be at the forefront of aging research applied to skin."

Dr. Felix Wong is a co-founder of Integrated Biosciences, an early-stage biotech company developing next-generation therapeutics for cellular rejuvenation. He is also a postdoc at MIT and the Broad Institute and was a lead author on a recent Nature Aging paper describing the use of graph neural networks to discover new senolytic compounds.
In this episode, Felix and host Chris Patil have an in-depth discussion about using machine learning to accelerate drug discovery, specifically to target cellular senescence. They explore how graph neural networks were trained on screening data to evaluate large chemical spaces and identify new senolytic molecules with medicinal properties superior to those of previously known compounds.
Key topics:
What cellular senescence is and why selectively eliminating senescent cells may have therapeutic benefits for aging and age-related diseasesLimitations of traditional high-throughput screening approaches and the vastness of chemical spaceHow graph neural networks work and how Felixâs team trained them on senolytic screening dataApplying the models to search much larger chemical libraries and identify promising new senolytic scaffoldsExperimental validation and characterization of hits from the AI screeningThe potential to use this machine learning approach more broadly for phenotypic drug discoveryFelixâs new company Integrated Biosciences and their mission to control cellular stress responses using synthetic biology and AIQuotes:
Quotes have been lightly edited for clarity.
"We found that machine learning models might allow us to more productively search chemical space and increase our working hit rates."
"What was fascinating to us about senescence cells is that, unlike other pathologies or diseases, these cells are not really characterized by a single target."
"The quality of any machine learning model is limited by the quality of the training data. And that in turn is limited by how good your screens are, and how good your understanding of the biology is."
âThat's really what machine learning is doing, trying to think about things in a very high dimensional manner. And then trying to build models that help to separate what is positive and what is negative.â
âSo what ideally we would want is for any model to be able to generalize, to be able to predict chemical scaffolds that the model has not previously seen, and positively identify those scaffolds as new senolytics.â
"Ideally, we would like to treat aging and age-related diseases, just like how antibiotics treat bacterial infections."
âAt Integrated, we're trying to kind of look at these stress responses holistically. We think that senescence is only a piece of the bigger puzzle.â

Joan Mannick, CEO and co-Founder of Tornado Therapeutics, joins the podcast to discuss her companyâs exciting mission of developing a new generation of rapalog compounds specifically targeting the TORC1 complex. Rapalogs are analogs of the natural compound rapamycin, which has been shown to extend lifespan and healthspan in animal models by inhibiting the TOR pathway. However, rapamycin has limitations that have prevented its widespread clinical use for aging-related conditions.
Tornado aims to overcome these limitations by developing a portfolio of novel rapalogs licensed from Novartis, which were specifically designed to be more selective TORC1 inhibitors with improved drug-like properties relative to rapamycin. Early data suggests these compounds may have an improved safety profile and remain effective at treating diseases like cancer.
In her conversation with host Chris Patil, Dr. Mannick provides an accessible overview of TOR signaling biology and shares insights from her extensive experience developing rapalogs. The discussion covers Tornadoâs strategic approach to indications like oncology and viral infections, the process of characterizing their licensed compounds, and notable milestones on the horizon.
Dr. Mannick provides an insider perspective on a compelling longevity biotech company striving to translate the promise of rapalogs into effective medicines for age-related diseases.
Key topics:
An overview of the TOR signaling pathway, the TORC1 and TORC2 complexes, and how the natural compound rapamycin inhibits TOR function.The benefits and limitations of using rapamycin/rapalogs clinically, and the need for more selective TORC1 inhibitors with improved drug properties.Tornadoâs licensing of novel TORC1-specific rapalogs from Novartis, including early safety data.Indications that Tornado is initially pursuing, including oncology and viral infection, applying lessons learned about rapalogs over the past decade.The experience of being a âpipeline companyâ within the Cambrian Biopharma family, and the synergies available to companies operating within this model.The maturation of the longevity biotech fieldPromising milestones on Tornadoâs horizon.Quotes:
Quotes have been lightly edited for clarity.
"Rapamycin is a very specific inhibitor of this critical protein mTOR that regulates lifespan and healthspan."
âAn ideal rapalog to treat aging-related conditions and extend lifespan is predicted to be a rapalog that specifically inhibits TORC1, but leaves TORC2 alone.â
"The problem with rapamycin is that it has no remaining patent life. And we really have to do the studies to see if the benefit outweighs the risks."
â[Cambrian] enabled me to go very fast in terms of execution - you get a team, which is very rare when you start a startup.â
"Longevity medicine is white space ready to be explored. It's an untapped area that could transform the practice of medicine."
âWe are picking indications where there's not just preclinical validation, but a lot of clinical validation.â
âWe're going to use these lessons learned to see if with a better clinical development plan, we can now develop our next generation rapalogs to enhance antiviral immunity and decrease severity of viral respiratory tract infections.â

Mitchell Lee is the CEO and co-founder of Ora Biomedical, a Seattle-based biotech company using large-scale phenotypic drug screening in C. elegans to discover small molecule therapeutics that extend lifespan and healthspan.
In this episode, Chris and Mitch discuss Ora's approach to drug discovery, which focuses on function and phenotype rather than specific targets or mechanisms. Using their proprietary "WormBot" platform, Ora screens thousands of compounds in parallel to identify molecules that impact lifespan, healthspan, and age-related disease phenotypes, allowing them to discover new longevity interventions in an unbiased, hypothesis-agnostic way.
Key topics:
How Ora Biomedical was founded out of a conversation between Dr. Lee and his mentor Dr. Matt Kaeberlein about spinning out a company based on the WormBot technologyWhy C. elegans is a useful model organism for discovering fundamental mechanisms of aging that can translate to mammalsHow the WormBot platform uses imaging and machine learning to measure worm lifespan, healthspan, behaviors, and response to drugs at a large scaleOra's goal of screening 1 million compounds within 3 years to find the most promising longevity interventionsStrategies for translating hits from the worm screen into rare disease therapies and direct-to-consumer natural productsThe promise of longevity interventions discovered through unbiased phenotypic screening to prevent age-related diseases and transform human healthQuotes:
Quotes have been lightly edited for clarity.
âWhat really sets us apart is that we do phenotypic screening, in live animals."
"If you are finding interventions that target those fundamental drivers of aging, you expect them to have multiple different impacts on age-associated diseases. But as we test more longevity interventions, we see that they also have all kinds of different impacts on nonâage-associated disease models.
âItâs really just taking the geroscience hypothesis seriously: If an intervention impacts aging, itâs likely to have impacts across many different disease stages, even ones that we wouldnât necessarily think about as being related.â
âWe've seen examples of how this plays out with things like rapamycin. So it's really incredible the types of therapeutic benefits that can be had through these kinds of interventions.â
"There's going to be a never before seen boom in enthusiasm, interest, engagement, and demand for longevity therapeutics. And what we're doing today is putting ourselves in the position where we're going to be able to meet that challenge in the next three to five years."

âA lot of people here asked me the difference between working on diseases of aging versus aging itself. And I think a lot of people aren't aware that age-related diseases like cardiovascular disease, Alzheimer's disease, even cancer â these are late-stage manifestations of the aging process itself.ââI think it's incumbent on us within the longevity community to go seek out the tool developers because they are inundated with all this interest from other players in other fields.âStephanie Dainow
âWhen it comes to aging, a lot of people you are under the impression that you're born, you will age there probably will be suffering, and then you will die. And that is the cycle of life. Right? That's kind of a standard. And I think this field is pushing that narrative in a direction that is uncomfortable because we're not used to it.ââIncentive structures matter. And in longevity, there aren't a lot of organizations that have products yet â forget the supplements, I'm talking about therapeutics â and that means that there aren't business development people, which means there's no selling, which means there's no marketing, which means there's no focus on articulation of the best way to create a narrative around the value prop.âDan Goodman:
âSynthetic biology has lots to offer, as far as measurement and diagnostics and being able to cheaply and at scale measure the effects of aging and the effects of longevity therapies on large populations.ââAs we get more comfortable, and we get more and more skilled at deploying these tools for disease, it'll be to the point that healthy people will be willing to take these sorts of therapies. and we can do so much to modify the body and immune... -

âI think what makes it unique is the focus on really early stage talent, and going after people that aren't already interested in aging, as well.â
âThe idea of the geroscience hypothesis is so compelling, that I feel like just the exposure is enough.â
âI want to firmly establish it as a key driving force in the field of aging. I want to grow our networks of fellows, our mentors and our partners. I envision a future where our fellows are empowered by this experience through our program and they become influential figures in the field.â
"The opportunities and possibility of the impact we can have in people's lives...is worth that extra funding and really deserves extra attention."
"I want them conducting cutting-edge research and pioneering innovative treatments."
"Stay curious. Be bold. Ask the questions, look for answers.

Jacob Kimball is the Head of Research and co-founder of NewLimit, a company aiming to develop epigenetic reprogramming therapies to treat age-related diseases and extend human healthspan.
In this episode, Chris and Jacob have an in-depth discussion about NewLimitâs mission and approach. They explore how NewLimit is leveraging epigenetics and machine learning to search for new ways to reverse cell aging without changing cell identity. NewLimit is systematically testing combinations of biological factors that can reprogram cell age, using both biological experimentation and computational modeling at scale, and Jacob shares insights into the cutting-edge science and technology behind this work: how functional genomics allows NewLimit to run hundreds to thousands of experiments in a single dish, how machine learning is used in their research, and the challenges of translating epigenetic reprogramming from the lab to the clinic.
Listeners will gain a deeper understanding of the promise of epigenetic reprogramming to revolutionize how we treat aging and age-related disease.

Epigenetics as a regulator of gene expression in cell differentiation and agingNewLimitâs mission and approach to tackling the challenges in aging research through epigenetic reprogrammingThe potential for age reversal built into our biologyHow NewLimit is using machine learning and biological experimentation in combination to generate new hypotheses and discoveriesThe potential for epigenetic reprogramming to improve the function of the aging immune system The biggest challenges in translating these discoveries to medicines, including delivery, pharmacokinetics, and ensuring safe and durable effectsA vision for how rejuvenation biotech could transform health and society in the coming decades if key breakthroughs are madeQuotes:
"Epigenetics is this layer of regulation that tells your cell, âWhich genes can I use from my genome, at which times?â"
"Our goal as a company is to increase human health span, and the way I like to frame that more colloquially is we want to increase the number of happy, healthy years each person gets to spend on Earth."
âEven with just those sorts of data available, we're already able to build models that perform better than randomly searching through the experimental hypothesis space, and already performed better than our rough heuristics about which interventions might be most impactful.â
"We know that you can actually just express these four genes and reprogram even an old cell all the way back to an embryonic-like state, which not only changes the cell's type, the role it's playing, but also its age."
"Our approach is trying to discover ways we can reprogram cell age without reprogramming cell type."
"The challenge that we run into is that there are so many combinations that very quickly it would become intractable to line up enough test tubes to test them all.â
"Transient interventions could have durable phenotypic benefits for a patient. However, that space hasn't been explored very richly. We know very little about just how long some of these interventions last."
âI think what I'm strongly hopeful for is that, if such medicines are to exist, that you can actually increase the number of happy, healthy years each one of us gets.â
âI think in the next five to 10 years, we're going to see some of the first applications of this technology and the clinics, some of the first proof points, that these interventions actually can benefit patients in a material way.â
âWhat I hope that means for someone like myself is that the number of years in which I can plausibly consider hiking the John Muir Trail increases in a measurable way. And likewise, for those of you with other hobbies, I hope that these sorts of...

In todayâs episode, Chris is joined by Dr. Matthew "Oki" O'Connor, CEO for Scientific Affairs at Cyclarity Therapeutics, a company focused on eliminating arterial plaque, a prevalent issue in old age. Dr. O'Connor shares his insights on the causes and effects of atherosclerosis, the leading cause of death worldwide, and how aging contributes to plaque build-up. The podcast emphasizes the need for a paradigm shift in addressing cardiovascular disease and highlights the importance of new approaches to repair vessels throughout the body and brain.
Together, Chris and Dr. OâConnor begin by discussing atherosclerosis, its significant impact on cardiovascular disease, and the need to understand the molecular and biochemical mechanisms underlying aging and diseases related to aging. They also cover the limitations of current clinical treatments for atherosclerosis and the importance of a paradigm shift towards new approaches that can repair vessels throughout the body and brain. Dr. OâConnor then goes on to describe Cyclarityâs unique drug, a cyclodextrin, explaining how it could be a promising solution to the harmful effects of atherosclerosis. The podcast also explores the potential of combination therapy with traditional lipid-lowering drugs to address multiple aspects of atherosclerosis.
Join Chris and Dr. OâConnor here today to gain a greater understanding of the remarkable work undertaken by Cyclarity Therapeutics, the impact of aging on cardiovascular health, the need for new approaches to address atherosclerosis, and the unique drug therapy combination that may offer a promising solution, revolutionizing its treatment in the process.

"Cardiovascular dysfunction, depending on which metastudy you believe, between 30 and 50% of all death on the planet is caused by the build-up of plaque in the arteries."
"Atherosclerosis is the thickening of the arteries, which means in the vessel wall, you have a build up of material called plaque, which starts out as a fatty streak in the wall of a blood vessel."
"There's no way to avoid the concept or the idea that a basic molecular mechanism, a biochemical mechanism of aging is going to impact many, if not all, cells and tissue systems."
"By the time that you're doing vascular surgery on somebody, you've kind of lost the game. You clearly missed an opportunity to prevent a bad thing from happening in the first place."
"We really need a paradigm shift to look at new approaches to addressing cardiovascular disease."
"I think the average non-specialist just thinks of cholesterol as this, like, weird molecule that's in your body for some reason, but is totally bad."
"Those lipid lowering drugs do actually save lives and keep atherosclerosis from getting worse faster. But we are trying to invent a better way to do it, a more elegant way to get rid of only the most toxic forms of cholesterol so that your arteries can repair themselves the way that they're engineered to."
"I imagine that our treatment, at least at first, will be paired with the standard of care, which...
