SEOUL, South Korea, Nov. 7, 2026 /PRNewswire/ — Cancer drugs keep improving, but
their limits remain. When antibody therapies first emerged, only a fraction of patients
benefited, and small-molecule anticancer drugs often carry severe toxicity. Rather
than developing a new anticancer drug, Park Shin-young, CEO of VS Pharmtech ([https://www.vspharmtech.com/](https://www.vspharmtech.com/)),
has focused on an "anticancer efficacy enhancer" that strengthens existing treatments.

Shin-Young Park CEO of VS Pharmtech

Park graduated from Seoul National University’s School of Applied Biology and Chemistry.
He then worked in planning roles at Daewon Pharmaceutical, SCM Lifescience and CLIPS,
a clinical research company. "Whether a new drug can be commercialized is decided
in the clinic," Park said. "I was drawn to the fact that you can gauge a drug’s 
chances of success early, at the clinical stage."

The company grew out of a patent advisory meeting at the Korea Institute of Radiological&
Medical Sciences in late 2018. There, Park encountered research on combining an 
existing drug with radiation therapy to improve its anticancer effect. He suggested
that developing the approach into an efficacy enhancer could give it much wider 
use. He was offered the chance to start a company on the spot and founded VS Pharmtech
that November.

A 20-year-old drug at one-fifth the dose

The company’s lead pipeline candidate, VS-101, is a radiosensitizer that makes tumors
more responsive to radiation so that more cancer cells die. When radiation damages
a cancer cell’s DNA, the cell detects the damage and tries to repair it. VS-101 
weakens RAD51, a protein central to that repair process, and drives the cancer cell
toward death.

VS-101 is being developed through drug repositioning, which finds new uses for an
existing medicine. In this case, the drug has been used for more than 20 years. 
The company aims to give patients only about 20% of the original dose. "The drug
itself doesn’t cause DNA damage or toxicity," Park said. "We designed the dose so
that patients receiving other cancer treatments can take it alongside them without
strain."

The first results came from a Phase 1 trial in Korea. Seven patients with stage 
1–3 head and neck cancer received VS-101 together with radiation therapy. All seven
achieved complete remission, meaning their tumors disappeared, with no dose-limiting
toxicities or serious adverse events.

Based on these results, the U.S. Food and Drug Administration (FDA) approved the
company’s Phase 2 plans for head and neck cancer, breast cancer and glioblastoma.
These trials extend to patients receiving chemotherapy and radiation together, adding
VS-101 to cisplatin for head and neck cancer and to temozolomide for glioblastoma."
This means the FDA recognized that VS-101 causes no significant harm when combined
with other anticancer drugs," Park said. "We expect approval for a trial in hard-
to-treat ovarian cancer, in combination with a PARP inhibitor, in the first half
of next year." The current trials, run at U.S. institutions including Yale Cancer
Center, add VS-101 to standard chemoradiation for patients with advanced head and
neck cancer. The goal is to improve outcomes without additional side effects.

Seeking joint research at Berkeley

VS Pharmtech is pursuing commercialization on two tracks. For VS-101, it plans to
discuss global licensing deals based on interim Phase 2 data. For its preclinical
candidates, which are covered by new-compound patents, it is negotiating region 
by region. One option is to supply them as payloads to antibody-drug conjugate (
ADC) developers. The company is in talks with firms in the Middle East, Latin America,
Japan and China.

The company is also expanding its overseas footprint. It was selected for MARU SF,
run by the Asan Nanum Foundation, and then for Bakar Labs, an accelerator program
at UC Berkeley. VS Pharmtech is the first Korean company admitted to Bakar Labs."
The first resident company we reached out to was Catena Biosciences, founded by 
former students of Professor Jennifer Doudna, the 2020 Nobel laureate in chemistry,"
Park said. "We plan to actively pursue joint R&D with member companies."

Going abroad has not been without difficulties. "Getting FDA approval for a Phase
2 trial doesn’t cost much, but it serves as official recognition that you can run
clinical development overseas," Park said. "I hope there will be more government
programs, training and patent support that let companies practice this process in
advance."

VS Pharmtech has raised a cumulative KRW 18.6 billion (about US$13 million) and 
is currently raising additional funding. It aims to list on the KOSDAQ in 2027 and
has already appointed a lead underwriter to plan its timeline. "The timing of the
listing will depend on when we close a licensing deal and how large it is," Park
said. "We hope to share good news soon."

The company is also a resident of SVC Seoul, a global startup hub in Seoul’s Hongdae
area. The hub was established to connect startups with strong overseas growth potential
to companies, universities, and investors in Korea and abroad.
