The pharmaceutical company will be offering 8.3 million common shares at a price range of US$ 14 to US$ 16 apiece and if the midpoint of the proposed range is considered, then Theseus Pharmaceuticals would have a fully diluted market value of US$ 593 million.
Established in 2017, Theseus Pharmaceuticals was started to improve the lives of cancer patients. The company is in the process of developing “pan-variant” targeted therapies to address the issue of drug resistance mutations.

According to Theseus, drug resistance mutations limit the efficacy of existing targeted therapies and that affects the lives of patients suffering from cancer. The company is led by pioneers who discovered and developed tyrosine kinase inhibitors (TKIs), which the company believes is the only way to address cancer resistance.
As of now, Theseus' leading program is known as KIT (THE-630) which is IND-enabling stage. In this stage, pharmaceutical companies aim to get approval to conduct their first-in-human clinical trials with a new drug.
The KIT (THE-630) is being developed for the treatment of gastrointestinal stromal tumors and Theseus Pharmaceuticals is expected to apply for approval for in-human clinical trials in the fourth quarter of this year.
