I found Corvus Pharmaceuticals literally by accident when I saw their announcement about the FDA fast track being granted for one of their drugs Soquelitinib in addition to breaking out of a downtrend since reducing their cash burn in the most recent financial update.

Unlike Dimerix and Aussie Fave CSL, Corvus appears to acknowledge the challenge of Rituximab, but mainly because the CEO was part of that development team as shown by the slides in their investor presentation.

As a reminder, Rituximab is used for Kidney disease in a "unofficial" capacity due to its function in suppressing autoimmune response. But it is interesting they have not added Kidney disease yet.

This drug is still in Phase 2 but will enter Phase 3 soon.

One company to watch if you are a Dimerix or CSL shareholder I think.

Checked the latest quarterly and there is no update for the recruitment.

In my last post, I mentioned that they should be completing recruitment around mid-July

We are past that point now.

DXB also spent lots on opening up trial sites and now have less than 2 quarters of cash at the current burn rate although that should reduce

I've sold already after holding for more than 12 months (time flies!) because of lack of update on the recruitment in the last presentation and announcements which I believe is a significant milestone that should be disclosed regardless of progress.

Not a company making deal but still progress. Only 350k advanced payment for mainly the middle east.

On the fence while we wait on trial update and other deals. So not sure on selling after June for something else

Another view from Eamonn Datt of Datt Capital

What’s one quality ASX micro-cap company that has so far been largely missed by the market, but has the potential to grow strongly from here?

This is a treatment for Focal segmental glomerulosclerosis (FSGS), a kidney condition that may lead to irreversible renal damage. DXB has received an orphan drug designation for DMX-200 providing a range of attractive commercialisation benefits for the company in the case of Phase 3 success.

While the company continues to progress its Phase 3 studies, there is a significant opportunity to progress discussions with potential commercialisation partners. Given the relatively modest market cap of $160 million, what we perceive to be lower technical risk with the Phase 3 study and attractive valuation relative to peers – DXB potentially represents an attractive risk-reward investment proposition; with the caveat that investing in health sciences is a higher risk endeavour.

Found some good information on Chemokine inhibitors, how they work and challenges

Molecular determinants of antagonist interactions with chemokine receptors CCR2 and CCR5

I won't provide too much from the link but my understanding is that Chemokines are like pathways for the immune system to move to places of infection. Some key statements:

The human immune system is a remarkably intricate and precise network of specialized cells, meticulously coordinated to protect the body against injury and infection, yet its damage and dysregulation results in devastating disease states such as inflammatory and autoimmune disorders. On a wide variety of immune cells are transmembrane chemokine receptors which, in normal physiology, play pivotal roles in orchestrating immune cell chemotaxis and migration to sites of injury and inflammation via interactions with their endogenous chemokines

AND

Among factors contributing to clinical failures are suboptimal properties of drug candidates [29]. At least in inflammatory contexts, therapeutic efficacy of chemokine receptor inhibitors has been linked to high in vivo receptor occupancy over extended periods of time [47,48]. This is a challenging task, given that CCR2 antagonists have to competitively inhibit what effectively is a high-affinity (sub-nanomolar) protein-protein interaction (receptor-chemokine) with abundant levels of the competitor (chemokine). To further complicate the situation, all known inhibitors of the CCR2-CCL2 system result in an apparent “CCL2 induction” where plasma chemokine increases far above pre-treatment levels. Although this phenomenon has been known for a long time [37–39,43], only recently we started to understand and appreciate its convoluted biological mechanisms which involve constitutive production of CCL2 by tissues, constitutive uptake and intracellular degradation (“scavenging”) of the chemokine by CCR2, and the inhibition of such scavenging by drugs [49,50]

Already there have been a few failures in using Chemokine blockers for treatment of Kindey disease. Some notable ones include the following:

Bristol Meyers Squibb

BMS-813160 | CCR2/CCR5 Antagonist

Diabetic Kidney Disease Terminated Phase 2 Trials for BMS-813160

Vifor in partnership with ChemoCentryx (Vifor now part of Aussie favourite CSL)

VFMCRP Press Release Phase-ii Lumina-1 Trial of Ccx140

ChemoCentryx now acquired by Amgen

Need to do more research whether Dimerix has really cracked the holy grail of chemokine blockers in kidney disease where others have failed.

Didn't want to make other holders nervous as it is now tempting to sell given the above and also that Corticosteroids were not mentioned by Dimerix as the main pathway for treatment (they could have been referring to the above trials in their slides).

In my view, I've gained a lot of understanding on this topic given I know someone who is diagnosed with kidney disease.

So been a good experience holding DMX overall.

[held]

Although I have little medical background, I do know that Rituximab is one of the go-to drugs for Kidney disease, particularly FSGS which is the main focus for Dimerix's candiate DMX-200

What is Rituximab?

Rituximab is a cancer drug called a monoclonal antibody. Monoclonal antibodies target proteins on the surface of cancer cells. Rituximab targets a protein called CD20. (Cancer research UK)

The CD20 protein is also found on white blood B cells and is part of our immune system which is also where this gets interesting. When someone has kidney disease, the immune system come and fight the infection, but also may get too active and end up harming the kidney - similar to autoimmune disease. Rituximab is administered to reduce the number of B-cells and protect the kidney from further harm by the immune system.

So now Rituximab is not just used for cancer, but also treatment of Kidney disease due to the above characteristics.

Problems with Rituximab

By weakening the immune system, Rituximab can cause problems with other conditions and side-effects such as being more exposed to infections and viruses. Most critical one is the weakening of the Liver which is troublesome for people who had hepatitis B in the past. Weakening the immune system may activate hepatitis B lying dormant in the Liver. The obvious workaround is taking an antiviral such as Entecavir before taking Rituximab.

I've also been told that the Rituximab is not always successful in fighting kidney disease from one of the renal doctors. Usually there is 70-80% chance of treatment being effective

Opportunities/shortcomings for DMX-200

I haven't found much on how DMX-200 works. From the Dimerix website we know that DMX-200 is a chemokine receptor (CCR2) blocker taken in conjunction with Avapro/Irbesartan. But there could be lots of positives if DMX-200 can overcome the shortcomings of Rituximab.

We probably won't know too much until the Phase III trials are finished some time at the beginning of 2026 which is a long wait which I found when going to the clinical trials website.

Therefore much of the success in Dimerix hinges on license deals as well as any indication of the product being safer to use against the current treatments such as Rituximab

Anyway I thought I would share what is weighing on my mind while holding Dimerix.

[held]

After posting some great news on the Phase III trials, Dimerix does a $20m placement for 30c .

Seems lots of people kicking up a fuss for this raise as it favoured the "big end of town" over long term holders that held before the share price pop. Who then probably went on to sell their shares for short term profit this morning.

Not sure what to think of this placement. It was oversubscribed but seemed this was done at the expense of longer term holders that held before the update.

First time straw poster - so please go easy :-)

Was fortunate to catch the NEU train IRL prior to FDA approval (still hold and waiting patiently for Dec NNZ-2591 PH2 read-out), plus have tactical % allocations to other ASX listed biopharma such as IMM, IMU, PAR and TLX.

One have also added recently is DXB (Dimerix).

Their lead candidate drug is DMX-200 currently in PH 3 development - that treats FSGS (Focal Segmental Glomerulosclerosis), being a rare disease that causes kidney scarring and can lead to end-stage kidney disease.  

DMX-200 has been granted Orphan drug status by FDA and EMA - with FSGS market size est. at US$3B across the 7 major markets the company is targeting.

They have other drugs such as DMX-700, to treat Chronic Obstructive Pulmonary Disease (COPD). But have stated that DMX-200 is their main focus currently in bringing to market.

The companies strategy is to partner with specialist rare disease Pharma Companies to bring their drugs to market, and recently signed a DMX-200 licensing agreement with ADVANZ Pharma for territories Europe, UK, Canada, Australia, New Zealand.

DXB retains rights to all remaining territories (inc. US) and are currently working on finding additional partners.

Other than strategy and commercial similarities to NEU - What strikes me as interesting is that ADVANZ have agreed to a licensing deal, with upfront payment, sales milestone payments and tiered royalties - prior to FDA approval and prior to an important Phase 3 read-out upcoming ~Mar 15th 2024.

Sep Quarter 4C report, DXB had $6.8 M is cash, and subsequently just received the up-front payment from ADVANZ of A$10.7 M.

Even after this up-front payment, it remains un-clear whether they have enough cash to get DMX-200 to registration stage.

Should additional partnering deals be struck across the next two Quarters, with similar up-front components as with ADVANZ, then likely they will have the required cash to make registration.

Therefore the Mar 15th result read-outs are very pivotal.

DXB has a market cap of ~$60 M so still very much a micro-cap and highly speculative.
