An opinionated take on NEJM highlights for the third quarter of 2024

The new Humira? It’s not that often that you see industry-sponsored head-to-head studies of one biologic vs. another, but Abbvie took the plunge comparing risankizumab (Skyrizi) to ustekinumab (Stelara, J&J) a leading therapeutic for Crohn’s disease, a notoriously hard indication because of its unpredictable manifestations.  The risk paid off for Abbvie:  a significant advantage was seen for risankizumab which provided clinical remission in 60.8% of patients.  Abbvie probably had no choice:  ustekinumab biosimilars are expected on the market by 2025; absent a clinical advantage, most payers would have demanded patients

A Chinese study uncovers a new use for an old drug Bleeding in the small intestine is often due to vascular malformations and is difficult to diagnose and manage because 1) the area is hard to reach with a scope and 2) bleeding tends to be intermittent.  Existing approaches are cumbersome and far from satisfactory, which makes a recent blinded RCT study conducted in China exploring thalidomide use in those patients valuable – not only did it show a significant decrease in bleeding episodes after a course of 4 months

How the US taxpayer saved 25M+ people A short piece celebrating the 20th anniversary of PEPFAR, a program that few outside of the field of Global Health are aware of. The world is not always nasty and brutish – it’s a shame it’s not said a bit more often. PEPFAR at 20 — A Game-Changing Impact on HIV in Africa   A hypertension trend? A second study of an investigational antihypertensive drug in the Journal this year; are we back in the 80s or something?  Joking aside, cardiac and vascular

Hypertension?! Antihypertensive drugs are so 80s and 90s (well, except for pulmonary hypertension) to the point that I cannot recall when I last read research in the NEJM about a new blood pressure drug. One of the reason is that we have so many existing drugs (most of them cheap generics) but despite this, a fraction of hypertensive patients are refractory and cannot get to their blood pressure goal despite using multiple agents. This is where baxdrostat (CinCor Pharma) comes in; it is an oral drug blocking the synthesis of

Hearts and souls: An opinionated take on NEJM highlights for October and November 2022

A psychedelic for refractory depression While major depression is awful, treatment-resistant depression (as defined not responding to at least two different courses of therapy) is worse with sufferers stuck in a long dark tunnel of anguish without a light at the end of it. Since psilocybin (the psychedelic agent in so-called magic mushrooms) has shown some effectiveness in depression, it seemed reasonable to test its differentiated mechanism of action in this high need patient population.  In this study that was mostly Europe-based but included sites in the US (finally), patients

An innovative sales strategy for a pivotal drug; Novartis trailblazes with Leqvio

After the $9.7B acquisition of The Medicines Company two and a half years ago, Novartis is eager to demonstrate value with a successful launch of the primary target of the deal, Leqvio. This launch is also a key catalyst for new revenue generation at Novartis, due to a $9B patent cliff by 2026. Given the high-stakes nature of Leqvio’s launch, the decision of the Swiss pharma to employ a non-traditional sales strategy in several key countries, including US and England, is noteworthy.   Novartis paves an innovative commercial path for

An opinionated take on NEJM highlights for January-February 2021

Gene therapy in beta-thalassemia and sickle cell anemia Beta-thalassemia and sickle cell anemia are common genetic diseases of hemoglobin (Hb) which manifest themselves in the former through transfusion dependence, in the latter through painful vaso-occlusive crises that frequently land patients in the hospital in a pitiful state. BlueBird’s lentiglobin therapy is an ex-vivo gene therapy in which autologous stem cells are harvested, transfected with new HbA gene, and then returned to the patient. Because the HbA is slightly modified via a single amino-acid substitution (HbAT87Q), expression is trackable.  Now in

While we wait for our shot(s); an opinionated take on NEJM highlights for January 2021

Incremental progress in the fight to treat heart failure After a decade or more of relative quiescence in the 2000s, a volley of new therapies have come to the forefront in the pages of the NEJM: sacubitril valsartan (2014 – Novartis’ Entresto), various SGLT2 inhibitors such as dapagliflozin (2019, AstraZeneca’s Farxiga), vericiguat (2020 – Merck’s Verquvo), and now a 2021 entry from Amgen in the form of the cardiac myosin activator omecamtiv mecarbil. None of those are a panacea, and of the four listed, omecamtiv has the lowest efficacy profile

Closing a tough year: An opinionated take on NEJM highlights for December 2020

Cardiovascular health – go big or go narrow? A follow up on the development of evinacumab (Regeneron), an inhibitor of ANGPLT3 (see this opinionated take from 2017), confirming the safety and LDL reduction effect in a population of individuals with cholesterol levels refractory to other therapies (including PCSK9 inhibitors).  Given the history of PCSK9 inhibitors, the development path of this asset will be interesting to follow. Of the 6 trials listed on clinicaltrials.gov not one has anything close to a clinical endpoint – it’s all biomarker based. That will probably

We are back and catching-up: An opinionated take on NEJM highlights for Sep, Oct, and Nov 2020

Small but real progress in ALS: Despite enormous public attention and significant effort, ALS remains a disease for which the development of new therapies has been challenging. Animal models showed potential activity against ALS by sodium phenylbutyrate and taurursodiol, both old (generic) molecules. Now, their effect in combination therapy has been confirmed in a randomized controlled trial.  What’s especially interesting is that the effect at 24 weeks (the original duration of the trial) was a modest though statistically significant improvement in functional scores. However, the trial was extended with all

Tax dollars doing good work: An opinionated take on NEJM highlights for December 2019

The loneliness of the patent-less drug Colchicine is a very old drug commonly used in gout with an anti-inflammatory mechanism of action that is not well defined. It is a generic (although in the US, the story is somewhat peculiar) and therefore incentives are lacking for further development in new indications by private companies. Given a well-established (but not well-understood) connection between inflammation and cardiovascular events, some researchers have hypothesized and explored potential utility in patients with high cardiovascular risk – but this would have to be validated by a

An opinionated take on NEJM highlights for May 2019

TAVR for all? TAVR has become the standard of care for patients who need an aortic value replacement but are at high/medium surgical risk.  But what about those at low-risk? Two studies answer that question, one with the Edwards device and the other with Medtronics. Both show that TAVR is superior along a number of end-points (stroke, hospitalization duration, atrial fibrillation) both at 30 days and at 1-2 year. Long-term outcomes remain a question though. Low-risk patients are younger (mean age 73-74) and will live with their valves longer, which

Target assessment with genetic polymorphisms Please bear with me for a long (but interesting!) story. Bempedoic acid (Esperion) is an inhibitor of ATP citrate lyase (ACLY), an enzyme in the cholesterol synthesis pathway (upstream of HMG-CoA reductase, the target of statins). In a study of 2,230 patients at high risk for cardiovascular events, on maximum statin therapy, and LDL > 70 (basically the PCSK9 target population), bempedoic acid was well tolerated and lowered the LDL by around 16% – a substantial effect. This would potentially position bempedoic acid, an oral

Eating your way out of disease: An opinionated take on NEJM highlights for November 2018

Peanut medicine that won’t cost peanuts Allergy to peanuts is a major issue and though prevention is now possible in infants there is a huge population for whom actual survival is connected to vigilance in what they consume and availability of epi-pens. Desensitization to allergens is a well-established method to overcome an allergy, but it is typically done through injections, and it requires well calibrated micro-doses of the allergen.  Aimmune has been pursuing an oral approach with progressive dosing with peanut protein (AR101) and in a phase 3 trial, two

Primary care organizations are better ACOs when it comes to achieving savings Initial results from the Medicare Shared Savings Program ACO have been disappointing pointing to small to negligible net effects on net spending, but a clever analysis digging into the details shows that there is a silver lining. The key insight is to distinguish between ACOs that are health systems and those that are physician practice groups: health systems show no net savings (after bonus incentive payments) while physician group ACOs do. In the physician group ACOs, the savings

An opinionated take on NEJM highlights for April 2018

Are we nearing an asymptote with implantable cardiac pumps? Severe heart failure is common, and spare hearts for transplant are rare, which has led to the development of implantable mechanical alternatives. In the last few decades, progress has been immense, and in the latest installment of a 3rd (4th?) generation pump, outcomes have reached a level where survival of several years is the rule. Still, at every iteration incremental improvement is less, and performance remains well behind what happens with transplant in terms of complications such as infection, stroke, or

A-fib in heart failure – time to be aggressive Over the last 15 years, there has been a growing body of evidence for the effectiveness of catheter ablation to treat atrial fibrillation (a-fib), a condition for which the standard of care has been anti-arrhythmic medications. A-fib commonly coexists with heart failure but until now it has not been clear whether medication or catheter ablation would be the preferred treatment – we now have the answer, at least for patients with a substantially reduced ejection fraction. In a randomized trial of

Between the very common and the very rare – An opinionated take on NEJM highlights for October 2017

Between the very common and the very rare – An opinionated take on NEJM highlights for October 2017   Another tool for prevention in cardiovascular disease Taking aspirin daily has been standard of care for cardiovascular disease for decades, but attempts to demonstrate the additive usefulness of other agents to prevent clot formation have not been successful. Now things have changed: in a large study of patients with established cardiovascular disease, those who took rivaroxaban (Xarelto, Bayer) daily on top of aspirin did markedly better than with aspirin alone, although

An opinionated take on NEJM highlights for July 2017

Taking stock: two decades of progress in heart failure: Here comes a clever study using existing clinical trial data to assess progress in standard of care over time for heart failure. For each trial, the authors assessed the rate of sudden cardiac death during the early part of the study (excluding patients with ICDs), and it appears that between 1995 and 2014, it decreased by nearly half.  As always, in observational retrospective studies, one has to worry about systematic biases around the population that are included (i.e. are they really

A hammer finds new nails (which happen to be eyeballs) The insulin growth factor receptor 1 (IGF-1R) was once upon a time a popular cancer target pursued by multiple biopharmas each with their own humanized antibody, and each without much success. In 2013, River Vision licensed the Roche compound teprotumumab, to treat Graves’ ophthalmopathy, a condition in which hyperactivity of the thyroid gland causes (among many other issues) bulging eyeballs with esthetic, comfort, and sometimes severe visual implications for which treatment options are limited. Nobody quite knows why the ocular
