Key takeaways from recent episodes

Ep209: Mathai Mammen on Developing Drugs Against Undruggable Targets

  • **Drugging flat protein surfaces:** Roughly 80% of intracellular proteins lack the pockets or clefts required for conventional small molecule drugs, making them inaccessible to existing modalities. Parabolas addresses this by using alpha helical peptides that can traverse cell membranes and bind flat, smooth protein surfaces. The alpha helix structure works because its self-satisfied hydrogen bonds do not require water removal during membrane crossing, a property borrowed directly from naturally occurring transmembrane proteins.
  • **Platform differentiation from stapled peptides:** Earlier stapled peptide approaches like Aileron's used a single central chemical lock on the helix, leaving the peptide ends unstructured and limiting amino acid diversity to a small set of helix-compatible natural residues. Parabolas employs hundreds of distinct stabilization chemistries distributed across the full peptide, enabling use of over 3,000 synthetic amino acids. This produces a chemical search space of 3,000 to the power of 20 possible compounds, creating a structurally distinct and proprietary drug class.

Ep208: Gary Nabel on Developing a Vaccine for Epstein-Barr Virus

  • **Dual-target vaccine design:** GSK's earlier EBV vaccine using only GP350 achieved 80-90% reduction in infectious mono but failed to sterilize infection because it blocked only B-cell entry. MODEX's candidate adds the GH/GL/GP42 trimer to block epithelial-cell entry simultaneously. Vaccinated animals in humanized mouse challenge studies showed sterilizing immunity, the strongest preclinical benchmark available before human trials.
  • **EBV disease burden:** EBV causes approximately 200,000 cancer cases annually, spanning Burkitt lymphoma, Hodgkin's disease, gastric carcinoma, and nasopharyngeal carcinoma. Beyond cancer, mounting epidemiologic evidence links latent EBV reactivation to multiple sclerosis, lupus, and rheumatoid arthritis. This positions a preventive EBV vaccine as a potential intervention against a broad cluster of chronic diseases, not merely adolescent mononucleosis.

Ep207: Jason Coloma on Genetic Medicines for Kidney Diseases

  • **Genetics-first target selection:** Maze identifies drug targets by mining large population genetics databases — UK Biobank, FinnGen — to find gene variants that either cause disease or protect against it. The APOL1 program emerged from discovering that some individuals carrying two disease-risk copies of the variant never developed kidney disease, pointing to a protective secondary variant that a small molecule could phenocopy therapeutically.
  • **Modality focus reduces compounded risk:** When taking on novel biology targets with uncertain mechanisms, pair them with proven drug modalities rather than novel ones. Maze deliberately narrowed from multiple modalities — antisense, small molecules — to oral small molecules exclusively, reasoning that stacking biological uncertainty on top of chemistry uncertainty creates an unfavorable risk profile for a capital-constrained company.

Ep206: Lyn Baranowski on Inhalable Medicines for Severe Lung Diseases

  • **Oral drug tolerability gap:** Only 30% of the 300,000 annual U.S. pulmonary fibrosis patients are on approved oral therapies at any given time, and just 10% remain on treatment across a full year. Pirfenidone causes severe nausea and vomiting; nintedanib causes debilitating diarrhea. This leaves a calculated addressable U.S. market of $42B annually — 300,000 patients at $150,000 per patient per year — almost entirely untapped.
  • **Inhaled dose reduction mechanics:** Reformulating pirfenidone for inhalation drops the daily dose from 2,400mg to 200mg — a 92% reduction. Inhaled nintedanib drops from 150mg to 4mg. Despite these reductions, lung tissue drug concentrations measured via bronchoalveolar lavage show 27x higher AUC exposure than oral delivery, because the drug is deposited directly into the alveoli rather than distributed systemically.
