We are a commercial-stage pharmaceutical company pioneering novel cancer therapies and dedicated to the discovery, development and commercialization of first-in-class drugs directed against nuclear export for the treatment of cancer. Our scientific expertise is based upon an understanding of the regulation of intracellular communication between the nucleus and the cytoplasm. We have discovered and are developing and commercializing novel, small molecule Selective Inhibitor of Nuclear Export (“SINE”) compounds that inhibit the nuclear export protein exportin 1 (“XPO1”). These SINE compounds represent a new class of drug candidates with a novel mechanism of action that have the potential to treat a variety of diseases with high unmet medical need. Our lead asset, XPOVIO® (selinexor), was the first oral XPO1 inhibitor to receive marketing approval, receiving its initial U.S.
Selinexor and eltanexor are novel therapies that are oral SINE compounds specifically designed to force nuclear accumulation of multiple tumor suppressor proteins that function in the nucleus. Selinexor and eltanexor also force nuclear accumulation of growth promoting mRNAs by similarly preventing their export, which prevents the translation of these mRNAs into proteins and thereby lowers expression of the oncogenic proteins that these mRNAs encode. Additionally, blocking XPO1 leads to increased glucocorticoid receptor transcriptional activity in the nucleus, thus amplifying corticosteroid effects in sensitive tumor cells. The forced nuclear retention of these proteins can counteract a multitude of the cancer-promoting pathways that allow cancer cells with gene dysregulation to continue to grow, divide and invade tissues in an unrestrained fashion.

We are a clinical-stage pharmaceutical company developing therapeutics to modify the course of cardiopulmonary and other diseases including those that arise from aberrant signaling through the Abelson Tyrosine Kinase, and type III receptor tyrosine kinases including platelet derived growth factor receptors and proto-oncogene c-KIT ("c-KIT"). The Company’s multi-therapeutic pipeline includes IKT-001, a prodrug of imatinib mesylate, for Pulmonary Arterial Hypertension (PAH). IKT-001 was designed to improve the oral absorption, reduce GI side effects and enhance the safety of active pharmaceutical ingredients. IKT-001 is a prodrug of imatinib, an FDA approved treatment for certain blood and stomach cancers. We plan to seek approval from the FDA for IKT-001 in PAH as an orphan indication.

The Company’s multi-therapeutic pipeline is developing IKT-001, a prodrug of imatinib mesylate, for Pulmonary Arterial Hypertension (“PAH”). We have completed non-human primate safety studies and a bioequivalence clinical trial in healthy volunteers to determine the doses of IKT-001 that are equivalent to imatinib mesylate and the results are being utilized to set the doses in a Phase 2b trial to determine if IKT-001 could be a disease-modifying treatment for PAH.

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.
