We are a clinical stage biopharmaceutical company developing a pipeline of innovative products for the treatment of diseases with unmet medical needs, including familial adenomatous polyposis, or FAP, non-muscle invasive bladder cancer, or NMIBC, type 1 diabetes, or T1D, and rare/orphan cancers of the brain.
Our clinical assets are supported by three proprietary drug delivery technologies focused on improving bio-delivery and bio-distribution of drugs through either sustained delivery (Q-SpheraTM), direct delivery (MidaSolveTM), or targeted delivery (MidaCoreTM): · Our Q-Sphera platform: Our disruptive polymer microsphere microtechnology is used for sustained delivery to prolong and control the release of therapeutics over an extended period of time, from weeks to months. · Our MidaSolve platform: Our innovative oligosaccharide nanotechnology is used to solubilize drugs so that they can be administered in liquid form directly and locally into tumors. · MidaCore platform: Our gold nanoparticle nanotechnology is used for targeting sites of disease by using either chemotherapeutic agents or immunotherapeutic agents.

We are a clinical-stage biopharmaceutical company developing next-generation therapeutics to improve the lives of patients suffering from inflammatory eye diseases and ocular pain. Our research program focuses on a novel G Protein-Coupled Receptor, or GPCR, which we believe plays a key role in the pathology of specific ocular eye diseases of high unmet medical need. Our therapeutic approach involves targeting a specific member of this class of GPCR receptors called CMKLR1 (or ChemR23) that is involved in the inflammatory and pain modulation pathways that drive these conditions. Our lead clinical product candidate, urcosimod (formerly called OK-101), is a lipidated peptide (See Figure 1) designed to specifically bind to ChemR23 and block its role in producing ocular pain and inflammation. FIGURE 1:
Operating segments are reported in a manner consistent with the internal reporting provided to the Board. The Board allocates resources to and assess the performance of the segments. The Board considers there to be only one operating segment being the research and development of biotechnological and pharmaceutical products. Taxation The tax credit for the year represents the total of current taxation and deferred taxation. The credit in respect of current taxation is based on the estimated taxable loss for the year. Taxable profit or loss for the year is based on the profit or loss as shown in the statement of comprehensive income, as adjusted for items of income or expenditure which are not deductible or chargeable for tax purposes. The current tax asset for the year is calculated using tax rates which have either been enacted or substantively enacted at the balance sheet date.

MTX110, which is being studied in aggressive rare/orphan brain cancer indications including recurrent glioblastoma, diffuse midline glioma, or DMG, and medulloblastoma, is a liquid formulation of the histone deacetylase, panobinostat. Our proprietary formulation enables delivery of the product via convection-enhanced delivery at potentially chemotherapeutic doses directly to the site of the tumor, by-passing the blood-brain barrier and avoiding systemic toxicity. We have recruited the first cohort of patients in an ongoing Phase 1 study of MTX110 in recurrent glioblastoma. We have completed and announced the results of two Phase 1 studies in DMG. There is an ongoing Phase 1 investigator-initiated trial in medulloblastoma.

There is an ongoing Phase 1 investigator-initiated trial in medulloblastoma.
Following IND approval in December 2021, we are in the process of recruiting patients in a Phase 1 study to assess the utility of MTX110 in recurrent GBM. The Phase 1 study is an open-label, dose escalation study designed to assess the feasibility and safety of intermittent infusions of MTX110 administered by CED via implanted refillable pump and catheter. The study aims to recruit two cohorts, each with a minimum of four patients; the first cohort will receive MTX110 only and the second cohort will receive MTX110 but with the option of the treating investigator to re-position the catheter into an area of new lesion upon progression, with the objective of increasing tumor coverage and survival.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-10-22. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
