        <![CDATA[<p>The wild story of how a Cold War bioweapon became Botox — and how Allergan turned a sleepy ophthalmology drug into an enduring aesthetic franchise.</p><p>Every part of this story looks nothing like your normal blockbuster drug. Botox started its development storyas a Cold War bioweapon so lethal the CIA was thinking of using it on Castro. Decades later, an eye surgeon in San Francisco mortgaged his house and managed to bootstrap his way to a BLA– no venture capital needed! After a contentious sale to a sleepy eye-drop company called Allergan, it turned Botox into one of the most durable, recurring-revenue franchises in the history of medicine. </p><p>That cash cow provoked all sorts of financial battles–  a hostile takeover attempt involving Bill Ackman, a tax-inversion scheme with Pfizer that united Bernie Sanders and Donald Trump in opposition, and a far-fetched plan to rent a Native American tribe's sovereign immunity to protect a different drug's patents.</p><p><br>In this episode, we trace Botox from a 19th-century German sausage poisoning, through a Cold War weapons lab, an eye surgeon's garage-scale manufacturing operation, and into Allergan's decades-long reign — covering the science of why the drug still has no biosimilar, the "aesthetics stack" that turned it into a subscription business for faces, and the corporate finance drama (Valeant, Actavis, Pfizer and AbbVie) that followed. Along the way: exclusive interviews with Allergan's 95-year-old founding CEO, the scientist who helped manufacture the original drug substance in an academic lab, and the dermatologist who tried to repurpose Botox to treat depression.</p><p><strong>In this episode:</strong></p><ul><li>How a Clostridium botulinum strain donated for free by a Harvard professor became the physical basis of a multi-billion-dollar drug</li><li>Why the FDA's insistence on unique nonproprietary names (onabotulinumtoxinA vs. abobotulinumtoxinA) created an accidental, unbreakable competitive moat</li><li>How Allergan built the "surround the ophthalmologist" sales playbook — and later applied the same tactics to the aesthetic space. </li><li>The 2014 Valeant/Ackman hostile takeover attempt, and how Allergan fought back</li><li>How nearly every foundational piece of IP in the Botox story was given away for free by the academics who created it</li><li>Is there a new aesthetic bundle to build around incretin-based weight loss products? </li></ul><p><strong><br>Featuring quotes from:</strong> Gavin Herbert Jr. (Allergan founder and former chairman/CEO), Eric Johnson, PhD (Ed Schantz's research partner, University of Wisconsin), Eric Finzi, MD PHD (dermatologist and Botox-for-depression researcher), Brent Saunders (former CEO, Allergan/Actavis), and Amy Ingle, APRN (owner, Sweet Spot Medispo). </p><p><strong>Bibliography</strong></p><p><em>Selected sources.

        <![CDATA[<p>Blueprint Medicines was built to find the next Gleevec-style cancer drug. It ended up pivoting to allergic disease instead, and selling to Sanofi for $9B. This is the platform, the pivot, and who got paid.</p><p><br>Blueprint Medicines set out to be the natural sequel to Gleevec: a company founded by two of the scientists behind that landmark cancer drug, built to order by Third Rock Ventures' "venture creation" model, with a proprietary kinase-inhibitor library designed to drug the 517 other broken molecular switches Gleevec couldn't touch.</p><p>A decade later, Sanofi paid roughly $9 billion for the company... just not for a cancer drug. Blueprint's blockbuster asset, avapritinib (AYVAKIT), found its real market almost by accident: indolent systemic mastocytosis, a debilitating, often-undiagnosed mast-cell disease that took patients years to get diagnosed and had no approved treatment.</p><p><br>In this episode, we trace two threads at once: the science of designing truly selective kinase inhibitors, and the venture capital philosophy -- company creation, not just company funding -- that built Blueprint from a whiteboard sketch into a platform biotech. We cover the near-death Series B, the accidental discovery that opened up mastocytosis, the GAVRETO partnership that fell apart against a faster competitor, the Sanofi negotiation (CVRs and all), and the wide gap between what the venture firm and hired executives made versus what the founding scientists -- like Gleevec's co-inventor Nick Lydon -- walked away with.

        <![CDATA[<p>Blueprint Medicines was built to find the next Gleevec-style cancer drug. It ended up pivoting to allergic disease instead, and selling to Sanofi for $9B. This is the platform, the pivot, and who got paid.</p><p><br>Blueprint Medicines set out to be the natural sequel to Gleevec: a company founded by two of the scientists behind that landmark cancer drug, built to order by Third Rock Ventures' "venture creation" model, with a proprietary kinase-inhibitor library designed to drug the 517 other broken molecular switches Gleevec couldn't touch.</p><p>A decade later, Sanofi paid roughly $9 billion for the company... just not for a cancer drug. Blueprint's blockbuster asset, avapritinib (AYVAKIT), found its real market almost by accident: indolent systemic mastocytosis, a debilitating, often-undiagnosed mast-cell disease that took patients years to get diagnosed and had no approved treatment.</p><p><br>In this episode, we trace two threads at once: the science of designing truly selective kinase inhibitors, and the venture capital philosophy -- company creation, not just company funding -- that built Blueprint from a whiteboard sketch into a platform biotech. We cover the near-death Series B, the accidental discovery that opened up mastocytosis, the GAVRETO partnership that fell apart against a faster competitor, the Sanofi negotiation (CVRs and all), and the wide gap between what the venture firm and hired executives made versus what the founding scientists -- like Gleevec's co-inventor Nick Lydon -- walked away with.

        <![CDATA[<p><strong>Keytruda</strong> is Merck's $31 billion a year <strong>PD-1 inhibitor</strong> and the best-selling cancer drug of all time. In Episode 3 of <em>Approved</em>, Alex Kesin and Matthew Pech trace the development of <strong>pembrolizumab</strong> , featuring interviews the scientists who drove the program forward : co-inventors <strong>Gregory Carven</strong> and <strong>Michel Streuli</strong>, and former <strong>Merck</strong> oncology CMO <strong>Roy Baynes</strong>.</p><p>Topics include preclinical <strong>PD1 / CTLA-4 checkpoint biology</strong> that brought industry attention to the target (Jim Allison's CTLA-4 work and Tasuku Honjo's PD-1 discovery); how pembro started as a failed rheumatoid arthritis antibody program at a Dutch subsidiary of a paint company; the two mega-mergers that nearly killed the program;  the <strong>biomarker enrichment</strong> trial design behind KEYNOTE-024 that let Merck break BMS's lead in lung cancer;  the 41-patient Johns Hopkins MSI-H trial behind the first tissue-agnostic FDA approval, and the <strong>Jimmy Carter</strong> melanoma case that brought pembrolizumab to the public conscious. The episode closes on what comes next for Merck: the 2028 patent cliff, the <strong>Keytruda QLEX</strong> subcutaneous launch, and efforts to find the next blockbuster checkpoint inhibitor, including Summit/Akeso's <strong>PD-1 / VEGF bispecific ivonescimab</strong>.</p><p>This episode is presented by <strong>JLL</strong>.
