Another bivalent biologic presented at #EADV2025, this time for #atopicdermatitis #eczema - IL-13 and IL17A/F inhibitor Galvokimig in a small phase IIA RCT

potentially very helpful for Asian Th17 AD phenotype or patients at risk of phenotypic switch

The third study presented at #EADV2025 from Novartis using spatial transcriptomics to look at #hidradenitis

Some beautiful pictures showing the distribution of fibroblasts, B cells, plasma cells, T cells around a lesion

IMO more data to suggest a need to hit multiple targets

Exciting to hear a new bivalent drug that targets TNF and OX40L Brivekimig for the treatment of #hidradenitis - we likely need more drugs that have multiple targets to treat this difficult disease

Looking forward to the explanatory phase III RCTs

Probably the closest effort to precision medicine so far in dermatology presented by Michel Gillet - using nanostring measuring gene expression - to differentiate between skin diseases outside of morphology

Good and slower burning response from OX-40 inhibitor rocatinlimab for #atopicdermatitis - results from the phase III RCT ROCKET-SHUTTLE which allows concomitant topical steroids

Really interesting new mechanism of action to target T-regulatory cells in #atopicdermatitis for Rezpeg

seems safe and effective in this phase 2b RCT but again this choice of as observed open label extension arm makes it difficult to interpret longer term effect

#EADV2025

Izokibep shows moderate response, again around 13% delta mark for HiSCR75 at week 12, for #hidradenitis

Not convinced more single target biologics are what we need

#EADV2025

Good to see phase III data for povorcitinib for #hidradenitis. Delta for primary endpoint of HiSCR50 slightly disappointing around 10-12%, but good to see draining tunnels resolving better.

Why use as observed imputation for extension, which is biased?

Do antibiotics have a direct anti-inflammatory activity in #hidradenitis? Some data to show they do, especially clindamycin, from a 3D seboskin model study from Germany

#EADV2025

Two interesting spatial transcriptomics studies in #hidradenitis highlighting abnormal epithelialisation and the complex immunological pathogenesis respectively in the EHSF session

Great to hear the new classification for epidermal differentiation disorders from Edel O’Toole, which follows a logical naming convention starting with the gene.

Delighted to have given a plenary on stories of drug discoveries and research in dermatology in my home town of Hong Kong! Thank you to Chester Lai and the GCDS committee for your kind invitation.

Great to hear from Henry Lim in the 1st plenary of the Global Chinese Dermatology Summit that ustekinumab and adalimumab are part of the WHO list of essential medicines!

Honoured to present on evidence based care in #psoriasis alongside amazing speakers for alopecia areata, urticaria, CTCL, acne, and photoaging at the #AAD2025 yesterday.

Learnt a lot from all the speakers on the topics at hand as well as how to get complex messages across

Much needed study on new therapies in bullous pemphigoid - more sustained remission for dupilumab after corticosteroid taper

#AAD2025

Slow and steady response for rocatinlimab, OX40 receptor inhibitor for atopic dermatitis

Looks like it is quite targeted and safe in this phase III study - but if the thought is a slower response they probably needed to have a later primary outcome timepoint

#AAD2025

Nice to see new therapies coming through for cutaneous lupus erythematosus - phase II data on deucravacitinib for CLE

#AAD2025
March 8, 2025 at 6:55 PM
Icotrokinra showing high but slightly lower response rates compared to injectable IL23i for #psoriasis - nonetheless a very high effectiveness for an oral medication

#AAD2025

Much needed study to look at the impact of dupilumab on itch in epidermolysis bullosa and ichthyosis

need a bigger study with a control arm but very promising!

ESK-001 showing promise as a targeted inhibitor of TYK2 for psoriasis in a phase II trial - now for the phase III study to confirm findings for blinded primary outcome

Very high negative predictor values presented by Skin Analytics for their DERM AI device in ruling out melanoma

I think gold standard for this based on dermatologist diagnosis is still suboptimal and would like longer term data with follow up

#AAD2025

Nice early results from a small phase IIa trial on Bempikibart, IL7/TSLP inhibitor biologic for alopecia areata in the late breaking session by Brett King

Looks like it results in more durable responses compared to JAK inhibitors after treatment cessation

Fascinating use of AI to increase access to patch testing for allergic contact dermatitis from the Mayo Clinic

Join me at #AAD2025 S065 Great Care for Common Conditions: Combining Evidence and Cost Effectiveness on Monday 10th March in Valencia Ballroom D

I will be presenting on Evidence based care of #psoriasis alongside great speakers @DrScottElman @DrShasaHu @AMostaghimi

Great to see a head to head trial in #atopicdermatitis comparing #upadacitinib to #dupilumab showing superiority for the JAKi approach - reassuring safely profile suggests a healthy population in this trial.
