@rkalyes1 Surely angels are light
The Messenger of Allah (ﷺ) said, "Angels were created from light, jinns were created from a smokeless flame of fire, and 'Adam was created from that which you have been told (i.e., sounding clay like the clay of pottery
@rkalyes1 Actually we have an explanation done specifically for roosters in our religious
Our prophet Muhammad said "When you hear the cock's crow, ask Allah for His favor upon you for surely it has seen an angel.
IBD Treatment Paradigms: past, present and future
by @IBDMD#DDW2025
What is a treatment paradigm?
Established approaches and strategies used in medical care for specific diseases or conditions
Involves a combination of therapies (surgery, medications and other interventions like diet) to achieve optimal patient outcomes
Traditional strategies that define treatment paradigms
• Sequential monotherapy
• Step up and combo therapy
• Targeted therapy
• Precision medicine
• Combination therapies
• Immunotherapies
OPTIMAL PATIENT OUTCOMES IN IBD
1. Unrestricted high QoL
2. Sustained control of bowel inflammation
3. Unencumbered personal and professional functioning
4. Healthcare that is affordable
General forces and factors in the development of treatments for IBD
· We do not know the cause and do not have medical cures
· Recognition of the chronic nature of IBD and phases of managements
· Development of outcomes of interest: short-term and long-term
· Evidence-based medicine
· Development of regulatory pathways for drug approval
· Advancements in technology
· Market forces and competition
Treatment paradigms in IBD
Desperation
Sequential monotherapy
Step-up
Top-down
Treat to target
Combination therapies
Biomarker driven
Cellular immunotherapy
The era of desperation in IBD marked by a multitude of evidence-free therapies: including horse serum, artificial fever therapy, hot water enemas, tincture of iodine and intracolonic insufflation of oxygen
Early surgical approaches in IBD: presumed “parasympathetic overactivity” or central nervous system causation; thymectomy in UC and bypassed loops of bowel in CD
Early approaches to diet in IBD: including elimination of raw fruits and vegetables, hyperalimentation with protein hydrolysates, bowel rest, fish oil
SEQUENTIAL MONOTHERAPY, STEP UP
Fail first, complications, delayed treatments
Treatment breakthroughs
Prontosil rubrum (1935, the source of sulfanilamide)
Antibiotics
Sulfasalazine (Professor Nanna Svartz, Karolinska)
Steroids
Mesalamine
Infliximab – taught us a lot about disease biology
Early step-up strategies –
Pyramids – staircases and lots of failures
Top-down – early effective therapy
This is the superior strategy for patients with Crohn’s disease
Proliferation of new therapies
Head-to-head studies in CD and UC – more are needed; the only trials that really change treatment practice / sequencing
Despite options and data, uptake by clinicians is not happening (Siegel CA Clin Trans Gastro 2020)
TREAT TO TARGET
Adjusting therapies until goal achieved
Challenges with treat to target
Crohn’s only –
Optimisation of one therapy, not sequencing to other MoA
Timing : how long to wait btwn assessments
How far to go
Need pragmatic research – verdict in UC, perianal, post-op
COMBINATIONS THERAPIES –
Breaking the therapeutic ceiling
Practical considerations
• Due to inadequate response
• Treatment of multiple diseases
Mechanistic considerations
• Additive efficacy
• Synergy
8 Durability
Safety considerations
Cost considerations
On-going combo studies
• DUET UC and CD
• EXPLORER 2.0
• ExiGEM
• Various diet studies
BIOMARKER DRIVEN elusive but promising
? will finally come of age with the biomarker in the TL1A studies
Consider clinical clues – cytokine-based strategies
The presence of other IMIDS gives clues to dominant biological process and therefore clues to treatment target
FUTURE CONSIDERATIONS
Emerging endpoints of interest
• Transmural healing
• Disease clearance
• Collateral remission (rheumatology) 0or functional remission
In progress STRIDE III (end 2025 / 26)
New(er) and novel treatments
- Improving existing MoAs
- New MoAs – novel small molecules, mucosal healing agents, cellular immunotherapy
- Pulse and de-escalation strategies
- Biome-based strategies
- Dietary strategies – elimination; modification
