ROCKVILLE, Md.--(BUSINESS WIRE)--Genexine, a clinical stage biotechnology company developing innovative biologics, and its spin-off company in the US, NeoImmuneTech, Inc. (NIT), today announced that Hyleukin-7, their investigational T cell amplifier, has been selected for inclusion in the Korea Drug Development Fund (KDDF)’s new drug development project. With the support of a KDDF grant and NIT’s participation, Genexine will conduct a phase 1b/2 clinical trial to investigate the safety and efficacy of Hyleukin-7 treatment in combination with Merck’s anti PD-1 therapy, KEYTRUDA® (pembrolizumab) in patients with triple-negative breast cancer.
"If successful, we believe this collaboration with Merck will give more clinical evidence for Hyleukin-7’s potential ability to reconstitute and reinvigorate the anti-tumor T cell immunity in TNBC patients, who tend to show relatively low response rates and poor survival for a checkpoint inhibitor treatment," said Genexine’s SVP, Head of Development Division, Jungwon Woo, Ph.D. “This collaboration will allow us to progress quickly in the clinic as a part of robust examination of Hyleukin-7’s broad applicability.”
The purpose of the study is to evaluate the safety and anti-tumor activity of the combination agents in patients with triple negative breast cancer. The trial aims to study Hyleukin-7’s effect on the efficacy of KEYTRUDA® by enhanced antitumor T cell immunity and increased TIL (Tumor Infiltrated Lymphocytes) count.
KEYTRUDA® is a registered trademark of Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., Kenilworth, N.J., USA.
About Hyleukin-7
Hyleukin-7 (IL-7-hyFc, NT-I7) is a T cell
amplifier, comprising a covalently linked homodimer of engineered
Interleukin-7 (IL-7) molecule, biologically fused with the proprietary
long-acting platform - hyFc™. IL-7 is known to be a critical factor for
T cells, acting on increasing both the number and functionality of T
cells. Hyleukin-7 could play a pivotal role in reconstitution and
reinvigoration of T cell immunity for treatment of cancer patients,
providing unique opportunities for Immuno-oncology (IO) combination
strategies. Hyleukin-7 is being developed as an “IO enabling” therapy to
harness T cell immunity in combination with many other cancer
treatments, especially with anti-PD-(L)1 agents or chemo/radiotherapy.
In a recent Phase I clinical trial in healthy volunteers, a single dose
of Hyleukin-7 was safe and well tolerated and substantially increased
the absolute lymphocyte counts (ALC) as well as the number of CD4/CD8 T
cells without an increase in the number of regulatory T
cells. NeoImmuneTech and Genexine are collaborating in three Phase 1b/2a
clinical trials in advanced solid tumors and glioblastoma in the US and
Korea.
About Korea Drug Development Fund (KDDF)
Korea Drug
Development Fund (KDDF), is a cross-ministry, full-cycle and
government-initiated R & D business entity that supports new drug
development beyond the boundaries of R & D. It was established by the
Ministry of Science, ICT, and Future Planning, the Ministry of Trade,
Industry, and Energy, and the Ministry of Health and Welfare to promote
