LOS ANGELES, Jan. 19, 2022 (GLOBE NEWSWIRE) — 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 positive interim clinical trial safety data demonstrating 100% completion of IMX-110 planned treatment cycles in its ongoing Phase 1b/2a clinical trial. Historically, 43-67% of patients have completed planned treatment cycles with approved drugs used to treat soft tissue sarcoma (STS) according to Demetri et al., 2016, and Schöffski et al., 2016. Completion of planned treatment cycles refers to lack of drug-related interruptions (cycle delays, dose reductions, or dose interruptions due to drug toxicity).

“With standard treatments widely used today, cancer patients face a long list of drug-related debilitating side-effects that cause treatment delays, dose reductions, or dose interruptions due to toxicity, interfering with the ability to treat them effectively,” said Ilya Rachman, MD PhD, CEO of ImmixBio. “In this interim clinical trial update, we are thrilled to report that IMX-110 has been well tolerated. We believe that IMX-110 could become a potentially attractive option to improve the patient experience in oncology in the future.”

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