  • S4E4 - Beyond Dopamine: Xanomeline-Trospium in Acute Schizophrenia
    2026/04/21

    Welcome back to What's it Worth! For over 70 years, the treatment of schizophrenia has been synonymous with dopamine D2 receptor blockade—until now. Join your host, Dr. Diana Langworthy, and guest Dr. Alexandra Rola (Psychiatry Clinical Pharmacist and Assistant Professor at Binghamton University) as they dive into the EMERGENT-3 trial. We're dissecting the efficacy and safety of xanomeline-trospium, a first-in-class muscarinic agonist that targets psychosis without the traditional side effects of dopamine antagonists. Is this the breakthrough psychiatry has been waiting for? Let's dive in and see what it's worth!

    Key Points

    • Unlike traditional antipsychotics, xanomeline is a dual M1/M4-preferring muscarinic receptor agonist. By pairing it with trospium (a peripheral muscarinic antagonist), the "KarXT" combination aims to deliver CNS antipsychotic effects while minimizing peripheral side effects like nausea and vomiting.
    • In this 5-week, Phase 3 trial of 256 adults with acute psychosis, xanomeline-trospium demonstrated a statistically significant and clinically meaningful 9.4-point greater reduction in the PANSS total score compared to placebo by week 5.
    • The study showed significant improvements in both the Positive Syndrome Scale (hallucinations/delusions) and the Negative Syndrome Scale (social withdrawal/apathy), suggesting a more holistic impact on schizophrenia symptoms.
    • While it avoids dopamine-related side effects, KarXT is associated with cholinergic-driven GI issues; nausea, dyspepsia, and vomiting were the most frequently reported adverse events.
    • What are the ethics of a placebo controlled trial in acute psychosis when we have proven medications for treatment? Join us for an important conversation about equity and ethics in clinical trials.
    • Can we treat psychosis without touching a single dopamine receptor? ------> Tune in to find out!

  • S4E3 - The GLP-1 Battle: Cardiovascular outcomes of Tirzepatide vs. Dulaglutide in the SURPASS-CVOT Trial
    2026/04/02
    Welcome back to What's it Worth! In this episode, your host Dr. Diana Langworthy is joined by Mia Lussier, PharmD, MS, Clinical Assistant Professor at Binghamton University and ambulatory care specialist, to dissect the results of the SURPASS-CVOT trial . As the first large-scale trial directly comparing a dual GLP-1/GIP agonist to a proven GLP-1 receptor agonist for cardiovascular outcomes, we ask: is tirzepatide officially the champion of metabolic and cardiovascular health? Join us for an evidence detective session as we evaluate the clinical worth of these findings Key Points SURPASS-CVOT was an active-comparator, double-blind trial that randomized 13,299 patients with Type 2 Diabetes and established ASCVD to receive either tirzepatide (up to 15 mg) or dulaglutide (1.5 mg) once weekly .Tirzepatide met its primary end point of noninferiority to dulaglutide for MACE (cardiovascular death, MI, or stroke) with a hazard ratio of 0.92. However, it did not achieve statistically significant superiority for this composite outcome (P=0.09)While CV outcomes were noninferior, tirzepatide showed superior metabolic benefits, including a -1.66 percentage point reduction in A1c (vs. -0.88 with dulaglutide) and an 11.6% reduction in total body weight (vs. 4.8% with dulaglutide).In a pre-specified secondary analysis of high-risk CKD patients, tirzepatide significantly slowed the decline of eGFR compared to dulaglutide, showing a difference of 3.17 ml/min/1.73m² over 36 months.Both agents had similar overall adverse event rates Was dulaglutide 1.5 mg weekly the best comparator vs tirzepatide for cardiovascular outcomes? ---> Tune in to find out!

  • S4E2 - The Kidney Formula Conundrum: Navigating eCrCl vs. eGFR in DOAC Dosing
    2026/03/20
    Welcome back to What's it Worth! Join your hosts, Dr. Diana Langworthy and guest Dr. Rachel Khan (Associate Professor at VCU School of Pharmacy), as they navigate the murky waters of renal function assessment in anticoagulant users. This episode dissects a critical insight from the ORBIT-AF II registry: the variability in DOAC (NOAC) dose eligibility when labs use newer kidney estimates . While clinical trials used Cockcroft-Gault (eCrCl), modern labs often report eGFR (MDRD or CKD-EPI), leading to a "renal identity crisis" for clinicians . We're putting on our EBP detective hats to explore why these formulas disagree—and what that means for your patients. Let's dive in and see what it's worth! Key Points The Gold Standard Gap: Landmark DOAC trials and product monographs almost exclusively use Cockcroft-Gault (eCrCl) for dosing, yet clinical labs have moved toward automated eGFR reporting . Formula Discordance: In the ORBIT-AF II cohort, agreement between eCrCl and eGFR was high overall (~93%), but declined in patients with established chronic kidney disease (CKD) . The "Misclassification" Mystery: Up to 42% of CKD patients could be classified for a different dose depending on which formula is used, with rivaroxaban showing the highest rates of variability . The Interpretive Challenge: While the study noted an association between formula-driven "undertreatment" and worse outcomes, we discuss the critical limitations—such as the lack of BSA-adjusted eGFR data—that make it difficult to conclude that eGFR is directly leading us to miss our target doses. Is your patient truly underdosed, or are we just using the wrong yardstick? ------> Tune in to find out! References [EPISODE TRIAL] Yao RJR, Holmes DN, Andrade JG, et al.

  • S4E1 | Asking Better Questions of Evidence in 2026
    2026/02/11

    In this brief 2026 season opener, host Diana Langworthy, PharmD, BCPS pauses to acknowledge the weight of the moment—particularly here in Minnesota—where uncertainty, fear, and harm are being felt in very real ways across communities.

    This episode is not about policy analysis or debate. It's a reflection on what it means to hold space for thinking, teaching, and care when the world feels unstable—and why asking good questions, slowing down our reasoning, and practicing intellectual humility still matter in healthcare education and clinical practice.

    Diana also shares how What's It Worth? will move forward this season, and how the podcast, Substack (whatsitworthpodcast.substack.com), and future TikTok (Diana the Pharm.D.etective - @whatsitworthrx) content will work together as connected—but distinct—spaces for evidence critique, reflection, and public-facing curiosity.

  • S3E14 | Defending Evidence in a Broken Trust Environment
    2025/12/19

    Welcome back What's it Worth? listeners.

    This episode steps away from traditional trial critique. It's a year-end reflection on what it means to practice evidence-based healthcare at a moment when trust in science, institutions, and clinicians is eroding—and when evidence itself is increasingly being misused to create fear rather than understanding.

    This episode is for frontline healthcare professionals and future providers who feel the weight of that shift and are asking how to respond without becoming part of a polarized conversation.

    The answer, I believe, is not louder certainty—but better questions.

    As we move into the next year, evidence-based practice will require more than knowing the literature. It will require clinicians who are willing to defend evidence with transparent communication, clarity, humility, and compassion—and who can help patients ask not just "Is there a study?" but "What's it worth?"

  • S3E13 | Secondary SBP Prophylaxis — Asking Better Questions of Retrospective Data
    2025/12/16
    Episode Summary

    Secondary prophylaxis after spontaneous bacterial peritonitis (SBP) has long been considered standard of care—but how strong is the evidence behind it?

    In this episode, host Dr. Diana Langworthy is joined by Dr. Ben Webber (hospital medicine physician) and Danielle Luettel (PharmD Candidate 2026) to unpack a contemporary observational study examining outcomes associated with SBP prophylaxis. Together, they explore how historical trials, modern resistance patterns, and guideline recommendations intersect—and where uncertainty still remains.

    As care evolves over time, it is important to revisit standard practices to ensure they still make sense. How we revisit them is important and strong internal validity is still what we need to make practice changing claims.

    Key Takeaways
    • Secondary SBP prophylaxis is rooted in strong historical evidence but largely based on older trials.
    • Contemporary observational data raise important questions about mortality benefit and patient selection.
    • Guideline recommendations still support prophylaxis, but resistance patterns and evolving microbiology matter.
    • Association does not equal causation—especially in retrospective database studies.
    • Does this retrospective cohort study rise above the rest? ---> Tune in to find out!

    2025/12/09

    Episode Summary

    SURMOUNT-5 delivers the first head-to-head comparison of tirzepatide vs semaglutide in adults with obesity but without diabetes.
    In this episode, host Dr. Diana Langworthy and expert guest Dr. Kylee Funk (clinical pharmacist in primary care at Mill City Clinic specializing in weight management and diabetes) unpack the trial's design, results, interpretation, safety considerations, and what these findings mean for real-world clinical practice.

    Key Takeaways
    • Tirzepatide achieved greater weight loss than semaglutide over 72 weeks.

    • Both drugs improved cardiometabolic markers with similar safety profiles.

    • Open-label design and exclusion criteria affect how broadly results apply.

    • Clinical decisions still hinge on access, coverage, tolerability, and goals.

  • S3E10 | GLP-1 Medications and Migraine - Exploring the Pressure Hypothesis
    2025/11/18
    🧠 Episode Summary

    Could a medication designed for weight loss change how we think about migraine prevention?
    In this episode, host Diana Langworthy sits down with returning guest Dr. Natalie Heinrich, PharmD and student contributor Nena Abosi, PharmD Candidate 2026 to unpack a 2025 Headache pilot study evaluating liraglutide as an add-on therapy for adults with obesity and high-frequency or chronic migraine. The team breaks down study design, results, and limitations while questioning whether the observed benefit stems from weight loss, intracranial-pressure changes, or something else entirely.

    💬 Key Takeaways
    • Study Design: Prospective open-label pilot (n = 31) using liraglutide 1.2 mg daily × 12 weeks in adults with BMI > 30 kg/m² and ≥ 8 headache days/month unresponsive to ≥ preventives.
    • Results: Headache days decreased by ~9 per month (≈ 50 % reduction); disability scores improved significantly, but BMI change was minimal.
    • Mechanism: Benefit appeared independent of weight loss—raising curiosity about GLP-1 effects on intracranial pressure and CGRP release.
    • Tolerability: Mild GI symptoms (~40 %), no discontinuations.
    • Caveats: Small sample, no control group, single center — results are hypothesis-generating, not practice-changing.
    • Clinical Pearl: Pilot studies like this spark conversation and awareness for emerging mechanisms while reminding clinicians to stay evidence-curious.
