Positive Outcome for Dimerix from PARASOLProject Sets Up FDA Meeting

Dimerix (DXB: $0.55) is all set to discuss with the FDA the decision to conduct a blinded analysis of its Phase III study with its lead drug candidate, DMX-200, for the treatment of the orphan kidney disease, FSGS. This follows outcomes from a collaboration with the PARASOL group. The PARASOL initiative was set up to assess the link between proteinurea and the risk of kidney failure.

The traditional measure of kidney degradation is eGFR, which is generally assessed after two years of drug treatment. However, proteinurea can be measured earlier, at 12 months. The outcome from the PARASOL review is that there is a potential relationship between proteinurea at 12 months and the risk of kidney failure from that point. That link needs to be agreed to by the FDA according to Dimerix CEO Nina Webster.

What this means for Dimerix is that it can now schedule a formal meeting with the FDA, with its US partner Amicus Therapeutics, to discuss an agreed regulatory assessment path for DMX-200 with respect to trial endpoints and potential accelerated approval.

There are a number of possible outcomes for Dimerix

  1. Dimerix actions a blinded review of the 12-month data using proteinurea levels from the 144 patients treated following FDA agreement. That data is currently available to review. The blinded data could either suggest that:
    a. The study is sufficiently well powered that it could generate a positive outcome from unblinding the data.
    b. The study is underpowered, which would require the trial size to be increased.
    c. The blinded data suggests there is unlikely to be a positive outcome.

  2. Dimerix elects to not unblind the data and continue with the study, using either a two-year proteinurea or eGFR endpoint to gain full approval.

If unblinding the proteinurea data yields a positive result, Dimerix could file for accelerated approval. It would then continue the study with the target 286 patients, with final (full) approval based on two-year eGFR data.

The first patient with FSGS was recruited into the pivotal study in May 2022. In February 2024, proteinurea data from the first 72 patients treated for 35 weeks had been collected. The next month, the company announced that blinded analysis indicated that a clinically meaningful and statistically significant result was possible from that data set.

In December last year, the company announced that the 144th patient had been recruited into the study. The 35-week data from these patients is now available for blinded analysis, pending FDA discussions on what should be assessed. The final patient of a total 286 patients is expected to be recruited by the end of this year. Patients in the study are treated for two years. After that, all subjects are invited into the open-label extension study. In September last year, the first patient entered the open-label extension study, with 56 patients electing to continue treatment with DMX-200.

Summary

Dimerix has secured four licensing deals for DMX-200, generating upfront payments totalling $66 million with a total potential deal value of up to $1.4 billion. Assuming a selling price of US$9,000 per month for DMX-200, the potential market in the regions where Dimerix has secured licensing deals is valued at $1.2 billion a year. In the main regions, Dimerix also stands to receive royalties of between 13%-20% from drug sales.

Dimerix is capitalized at $307 million.
