Experts in gastroenterology discuss treatment selection in special situations of CD, such as age, women considering pregnancy, and extra-intestinal manifestations.

Remo Panaccione, MD, FRCPC, provides an overview of the newest oral therapy approved for CD, upadacitinib.

Use of Upadacitinib in Treatment of CD

The discussion shifts to the newest drug for Crohn's disease, upadacitinib, a selective JAK (Janus kinase) 1 inhibitor. The speaker outlines the mechanism of upadacitinib, distinguishing it from other JAK inhibitors and emphasizing its selectivity for JAK1. The drug's impact on the JAK-STAT pathway and its role in modulating gene transcription for pro-inflammatory cytokines are discussed.

Upadacitinib is highlighted for its specificity in targeting JAK1 without significant effects on JAK2, which reduces the risk of off-target effects associated with myelofibrosis and erythropoiesis. The speaker explains that JAK inhibitors act as competitive agonists, binding to the intracellular side of the receptor and competing for STAT activation.

The drug's approval for Crohn's disease is discussed, with a comparison to another treatment mentioned earlier in the conversation. The speaker notes that the data for upadacitinib, an oral small molecule, aligns closely with the effects of the mentioned treatment, administered differently. The discussion emphasizes the drug's effectiveness in achieving clinical and endoscopic remission, with particular attention to its rapid action, possibly quicker than other options.

The speaker shares personal experiences, mentioning that upadacitinib is used as a first-line therapy for Crohn's disease in Canada for about 15% of patients. The drug is frequently used clinical practice, attributed to its quick efficacy and ability to rescue a significant number of patients. The convenience of an oral small molecule is underlined, especially in gastrointestinal diseases, addressing pharmacodynamic challenges associated with monoclonal antibodies in inflamed guts.

In summary, upadacitinib emerges as a remarkable and versatile drug, praised for its selectivity, efficacy, and oral administration. The speaker's experiences and the drug's potential as a first-line therapy contribute to its significance in the evolving landscape of Crohn's disease treatment.

Sequence Study of Risankizumab vs Ustekinumab in CD

The transcript discusses the findings of the sequence study, focusing on the comparison between two drugs, P41 (referred to as risankizumab) and P19 (referred to as IL (interleukin)-23 therapy). The study aimed to evaluate the efficacy of risankizumab in patients with Crohn's disease who had been exposed to TNF.

The results indicate that risankizumab-exposed patients were more likely to achieve clinical response, clinical remission, and endoscopic improvement compared to those on P40 (risankizumab with IL-12 and IL-23). The transcript emphasizes that the head-to-head comparison provides valuable insights, guiding clinicians in choosing the most effective therapy.

It highlights that risankizumab, along with its biosimilar, is an approved and effective option for Crohn's disease. The discussion touches upon the significance of the sequence study's second primary endpoint, endoscopic remission, and how it could be a pivotal moment in the field.

The conversation also touches on the evolution of clinical trials in Crohn's disease, emphasizing the importance of endoscopic outcomes and the progression from subjective measures to objective proof of efficacy. The participants express optimism about the potential impact of risankizumab, especially when used as a first-line therapy.

Furthermore, the transcript discusses the importance of early intervention in Crohn's disease, suggesting that initiating treatment early is more likely to result in a positive response and prevent further damage. The participants encourage setting higher expectations for patients and discuss the advantages of using risankizumab in biologic treatment-naive patients.

In conclusion, the discussion underscores the positive findings from the sequence study, positioning risankizumab as a promising option for Crohn's disease, particularly in terms of achieving endoscopic remission and improving patient outcomes. The participants stress the need for effective communication with patients about treatment options and the potential long-term benefits of early intervention.
