The story continues at a new index, nobrainerbio.substack.com/p/article-index. Current articles as of this writing: 1 - Fix the Tap, Don’t Mop the Flood nobrainerbio.substack.com/p/fix-the-tap-… The case for InflaRx — and why one forgotten molecule could be the most important anti-inflammatory asset in biotech An introduction to the C5a signaling pathway, vilobelimab, and INF904 — and why controlling inflammation at its upstream source changes everything. 2 - The Killer Nobody Names nobrainerbio.substack.com/p/the-killer-n… Why the modern world is killing us from the inside out — and what the leading causes of death are hiding Three in five deaths globally trace back to chronic inflammation — a public health crisis hiding in plain sight behind named diseases. 3 - HS - The Disease That Hides in Plain Sight nobrainerbio.substack.com/p/the-disease-… Seven years to diagnosis. Treatments that miss the point. And a molecule that could change both. Hidradenitis suppurativa — a neutrophil-driven inflammatory disease of the skin — and why every approved treatment targets downstream of the real problem. 4 - PG - The Wound That Shouldn’t Exist nobrainerbio.substack.com/p/the-wound-th… Pyoderma gangrenosum destroys tissue for no reason medicine can explain — and for forty years, the only upstream answer has been ignored. Pyoderma gangrenosum, the role of C5a and NETosis in its destruction, and why a flawed trial endpoint — not a flawed drug — derailed the first targeted therapy. 5 - AAV - Steroid-Sparing Isn’t Steroid-Free nobrainerbio.substack.com/p/steroid-spar… Reducing steroids was a milestone. Eliminating steroids is the goal. In AAV, no approved drug has crossed that line. ANCA-associated vasculitis, the limits of avacopan, and the pharmacological case for INF904 as the first drug capable of achieving true steroid-free remission. 6 - ARDS - The Body Sets Itself on Fire nobrainerbio.substack.com/p/ards-the-bod… A drug approved in Europe. An ICU full of dying patients. A bureaucratic wall between the two. Acute respiratory distress syndrome, the neutrophil-driven lung destruction at its core, and why a fully approved drug is sitting unused while patients die. 7 - DKD - The Kidney Nobody’s Looking At nobrainerbio.substack.com/p/the-kidney-n… Diabetic kidney disease is the leading cause of kidney failure worldwide. The standard of care slows it. It does not stop it...yet. Diabetic kidney disease, the C5a-C5aR1 signaling that drives its progression, and why INF904 may offer the first mechanism capable of altering its course. 8 - IgAN - The Young Kidney Claimed By An Ancient Protein nobrainerbio.substack.com/p/8-igan-the-y… Complement inhibition confirmed, a drug approved, still a flood. IgA nephropathy, the complement activation that drives it, and why blocking complement upstream may be the answer a newly approved drug class is still only partially providing. 9 - LN - When the Body Attacks Itself nobrainerbio.substack.com/p/9-ln-when-th… Three drugs approved. Six in ten patients still failing. The upstream trigger nobody has touched. Lupus nephritis, the classical complement pathway that fires with every flare, and why the molecule initiating each attack has never been targeted in a clinical trial in this disease. 10 - MN - When the Immune System Opens the Floodgates nobrainerbio.substack.com/p/10-mn-when-t… One million microscopic filters under autoimmune attack. A complement cascade the field has been misreading for fifty years. And an upstream target nobody has tried. Primary membranous nephropathy, the autoimmune trigger that destroys the kidney’s final filtration barrier, and why no complement inhibitor has ever been tested in the most complement-dependent kidney disease in nephrology.

Avacopan blocks C5a from activating its receptor. Izicopan does the same thing but without damaging the liver in the process. Avacopan inhibits a key liver enzyme that processes dozens of other drugs, including the steroids it was supposed to spare patients from needing. And its own breakdown produces toxic byproducts that can injure liver cells directly. Izicopan does neither. Same target, same mechanism but one leaves the liver alone and one doesn't. That difference is now documented in the public record, in the same month the FDA formally proposed pulling avacopan for eight liver toxicity deaths. nobrainerbio.substack.com/p/fp-5-why-did…

Avacopan is approved for use in ANCA-Associated Vasculitis, but both efficacy and safety are now dubious. FDA has requested withdrawal from market, but Amgen refuses. 20 death from drug now reported in Japan. Why might Izicopan be safer and better?

@GlassockJ @Abdelhamed6261 @DrDanMO Great question! CYP3A4 inhibition to start with.

The table attached is from Table 3 of Shi et al., Research 2026. Every neutrophil-targeted ICI combination currently in clinical trials, filtered to NSCLC-relevant rows only. spj.science.org/doi/10.34133/r… This is the second independent peer-reviewed paper in the same month to confirm neutrophil-driven NETosis as the primary ICI resistance mechanism in NSCLC, the first being the anchor paper in FP 4. Look at what's missing. Every single intervention operates downstream of C5a. CXCR1/2 antagonism blocks the neutrophil recruitment signal. But IL-8, the ligand that drives CXCR1/2, is itself generated by C5a. The navarixin row tells you how that bet ended. C5a → IL-8 → CXCR1/2 → neutrophil recruitment. Every drug in this table intervenes at step two, three, or later. A cell-permeable C5aR1 inhibitor intervenes at step one, and reaches the intracellular survival program in the hypoxic tumor core that no drug in this table can access. No such inhibitor has been tested in a patient with advanced NSCLC. That's the experiment waiting to be run. $IFRX #INF904 #izicopan

@JohnFitisoff "likely scheduled for June" investing.com/news/analyst-r… InflaRx has indicated CMD sometime this spring. Could be next week, next month, or June 19 I suppose. Why wait is the question...unless depends on some internal milestone...such as partnering details...

Saw a comment over on stocktwits that $IFRX capital day will be in June (Apparently mentioned in a report Guggenheim issued.) Can anyone confirm?

Thanks and yeah fair point on length. Substack rewards depth but X is a different medium :) On BD: agree completely. A small biomarker-rich PoC - NLR, calprotectin, H3.1 nucleosomes - could tell a mechanistically complete story in 20-30 patients, 12 weeks of treatment and steroid taper. That's the asset a partner licenses, not the Phase 3. Option deal makes sense here precisely because the biology is upstream of everything the market already pays $10B for. The PoC *is* the BD strategy.

@3in5saved Impressive work !! (a bit lengthy maybe 😉) How does it translate in terms of BD opportunity? A (speculative) one could be: option deal with a global partner to run a PoC trial (biomarker based ?). I usually consider option deals a red flag but not in this case. #InflaRx $IFRX

#InflaRx $IFRX – A personal, well-researched, speculative look into the potential of C5a-C5aR1 signaling control biotech. AAV, aHUS, FSGS, IgAN, LN, GN, CG, GS, RA, SLE, RF, TR, CIDP, CIPN, DM, BP, PASH, PAPASH, and CSU. All claimed indications listed in a recent InflaRx patent, patents.google.com/patent/AU20243…. This subset makes the pipeline shortlist in my view: AAV, IgAN, LN, BP, and CSU (the first 4 covered in the no-brainer series). nobrainerbio.substack.com/p/article-index RA (rheumatoid arthritis) is a contender: affects 18m people worldwide, is a $30b market shared by a dozen approved biologics and oral therapies, yet would present some study and market challenges. This leads to a related, underserved, multibillion-dollar arthritic indication. PsA (psoriatic arthritis): perfectly suited for study using the best-in-class oral C5aR1 inhibitor, izicopan. nobrainerbio.substack.com/p/14-psa-upstr…

Honing in on Prof. Guo’s comment, “favorable metabolic stability and human PK/PD profile,” and supporting data from today’s PR, there’s this view as well: “Based on available evidence, the most likely route is renal excretion or UGT-mediated glucuronidation — bypassing CYP enzymes entirely. CYP2D6 and CYP2C8 cannot be ruled out as minor contributors but are unlikely primary routes. The reasoning: a drug with confirmed metabolic stability, 10-fold higher systemic exposure than avacopan, and no CYP3A4 involvement is not being rapidly cleared by any major CYP enzyme. Slow, stable clearance points toward renal filtration or direct conjugation as the dominant pathway.” claude

I recently did a deep dive analysis of InflaRx patents, so I just went back to that Claude-supported session and inquired about alternative metabolic routes. “On the likely metabolic pathway — with appropriate epistemic honesty: The patents themselves do not contain detailed metabolic pathway information. This is inference from medicinal chemistry principles, not sourced fact. The INF scaffold is a lipophilic basic nitrogen-containing molecule — a piperidine/tetrahydroquinoline — with MW ~629 Da. For compounds of this structural class that are not primarily metabolized by CYP3A4/5, the most common alternative metabolic routes are: CYP2D6 — frequently handles basic nitrogen-containing compounds that CYP3A4 does not. Many piperidine-based drugs are CYP2D6 substrates. CYP2C8 or CYP2C19 — secondary CYP enzymes that handle a range of lipophilic substrates. Direct glucuronidation via UGT enzymes — bypassing CYP metabolism entirely. Some large lipophilic molecules are conjugated directly. Aldehyde oxidase — increasingly recognized as a metabolic route for nitrogen heterocycles. Given izicopan's structural features — the cyclopentyl group and the fluorobenzoyl arm are both potential metabolic handles — CYP2D6 or CYP2C8 are the most structurally plausible primary routes if CYP3A4/5 is not dominant. But this is pattern recognition from structural class, not verified data.” claude

Today's press release from $IFRX was written by scientists for scientists. Most people read it and moved on. We didn't. Translated it into plain language, including why a blockbuster allergy drug killed people in the 1990s and why that history is relevant to what was published today. nobrainerbio.substack.com/p/fp-3-the-bod…

#InflaRx $IFRX That tunnel reduction seen in the INF904-HS p2a data: WOW! Stopping the effector cell of the disease – neutrophils – by safely and significantly reducing the primary signaling that activates those cells – C5a signaling – leads to healing, even in that of the most severe forms of HS. Even the Vilo-HS p2b data, of the mAb acting on the C5a molecule itself, showed the same significant tunnel reduction result. HS is an endpoint definition problem, not – and never was! – a biology/mechanism concern as to whether C5a signaling plays a role in neutrophilic disease. As to CSU, these results are not a disappointment, especially in the angioedema cohort, highlighting the fact that neutrophils play their part in this disease as well, not just a mast cell party.
