– IMX-110 + anti-PD-1 produced 63-day median survival in a genetic (KPC) pancreatic cancer mouse model in which mice develop their own pancreatic cancer and have an intact immune system

– Historically, 42-days is the median survival produced by a 4-drug combination of 2 chemotherapies and 2 immunotherapies in the same genetic pancreatic cancer mouse model according to Winograd et al., 2015

– 2022 – plan to commence combination IMX-110 + BeiGene anti-PD-1 tislelizumab Phase 1b/2a clinical trial in advanced solid tumors

LOS ANGELES, Jan. 25, 2022 — Immix Biopharma, Inc. (Nasdaq: IMMX) (“ImmixBio”, “Company”, “We” or “Us”), a biopharmaceutical company pioneering Tissue-Specific Therapeutics (TSTx)™ targeting oncology and immuno-dysregulated diseases, today announced data showing that IMX-110 + anti-PD-1 produced 63-day median survival in a genetic pancreatic cancer mouse model in which mice develop their own pancreatic cancer and have an intact immune system. Historically, according to Winograd et al., 2015, 42-days is the median survival produced by a 4-drug combination: 2 chemotherapies (gemcitabine, nab-paclitaxel) and 2 immunotherapies (anti-PD-1, anti-CD40) in the same genetic pancreatic cancer mouse model.

“This data highlights why we are excited to collaborate with BeiGene on our planned 2022 Phase 1b/2a combination clinical trial of IMX-110 + BeiGene anti-PD-1 tislelizumab in advanced solid tumors,” said Ilya Rachman, MD PhD, CEO of ImmixBio. “We believe this upcoming combination clinical trial will allow us to rapidly expand into multiple oncology indications.”

The U.S. Food and Drug Administration (“FDA”) has approved orphan drug designation (“ODD”) for IMX-110 for the treatment of soft tissue sarcoma. Additionally, the FDA has approved rare pediatric disease (“RPD”) designation to IMX-110 for the treatment of a life-threatening pediatric cancer in children, rhabdomyosarcoma.

In January 2021, BeiGene and Novartis entered into a collaboration and license agreement granting Novartis rights to develop, manufacture, and commercialize anti-PD-1 tislelizumab in North America, Europe, and Japan in exchange for an upfront payment by Novartis of US$650 million plus royalties and milestone payments.

As of January 2022, anti-PD-1 tisleizumab has been approved or granted conditional approval in 6 cancer indications in China, including non-squamous non-small cell lung cancer (“NSCLC”), squamous NSCLC, classical Hodgkin’s lymphoma, Hepatocellular Carcinoma, and urothelial carcinoma.

About Immix Biopharma, Inc.

Immix Biopharma, Inc. (ImmixBio™) (Nasdaq: IMMX) is a clinical-stage biopharmaceutical company pioneering a novel class of Tissue-Specific Therapeutics (TSTx)™ targeting oncology and immuno-dysregulated diseases. Our lead asset IMX-110, currently in Phase 1b/2a clinical trials, holds orphan drug designation (ODD) by the FDA for soft tissue sarcoma, and has received Rare Pediatric Disease Designation (RPDD) for the treatment of rhabdomyosarcoma, a life-threatening form of cancer in children. RPPD qualifies ImmixBio to receive fast track review and a priority review voucher (PRV) at the time of marketing approval of IMX-110. Our proprietary SMARxT Tissue-Specific™ Platform produces drug candidates that circulate in the bloodstream, exit through tumor blood vessels and simultaneously attack all 3 components of the tumor micro-environment (TME). We believe ImmixBio’s TME Normalization™ technology severs the lifelines between the tumor and its metabolic and structural support. Learn more at www.immixbio.com.
