General Information

We are a clinical-stage biopharmaceutical company developing a novel class of Tissue-Specific Therapeutics (“TSTx”)TM in oncology and inflammation. Our lead product candidate, IMX-110, is currently in Phase 1b/2a clinical trials for solid tumors in the United States and Australia. IMX-110 is a negatively-charged TSTx that simultaneously disables resistance pathways with a poly-kinase inhibitor (which inhibits multiple kinases simultaneously), and induces tumor cell death with an apoptosis inducer (which activates apoptosis, a non-inflammatory programmed cell death pathway), leveraging our TME NormalizationTM Technology, delivered deep into the tumor micro-environment (“TME”). Our proprietary System Multi-Action RegulaTors SMARxT Tissue-SpecificTM Platform produces drugs that accumulate at intended therapeutic sites at 3-5 times the rate of conventional medicines. Our TME Normalization™ Technology allows our drug candidates to circulate in the bloodstream, exit through tumor blood vessels and simultaneously attack all components of the TME. As of the date of this prospectus, we have not generated any revenues. Since inception, we have devoted substantially all of our resources to developing product and technology rights, conducting research and development, organizing and staffing our Company, business planning and raising capital.

 As of September 2021, we have treated 14 patients in our ongoing Phase 1b/2a clinical trial in the United States and Australia. 100% of these patients received between 3 and 13 lines of therapy prior to IMX-110. Zero drug-related serious adverse events and zero dose interruptions due to toxicity have been observed in our Phase 1b/2a clinical trial to date. In our trial, we observed radiological progression-free-survival of 6 months in 50% of our STS patients, with a 4-month median progression free survival (“mPFS”) across all STS patients. mPFS is the time that patients live without their cancer progressing. The trial includes patients with leiomyosarcoma, carcinosarcoma, poorly differentiated soft tissue sarcoma, cholangiocarcinoma, colorectal cancer, prostate cancer, pancreatic cancer, esophageal cancer, breast cancer and nasopharyngeal cancer.

In August 2021, we entered into a Clinical Collaboration and Supply Agreement with BeiGene Ltd. (“BeiGene”) for a combination Phase 1b clinical trial in solid tumors of IMX-110 and anti-PD-1 Tislelizumab (the subject of a collaboration and license agreement among BeiGene and Novartis). In genetic mouse models of pancreatic cancer, IMX-110 has demonstrated an immunomodulation effect, turning “cold” tumors “hot,” and, in combination with murine anti-PD-1, IMX-110 produced extended survival versus multi-drug combinations. The goal of this study is to demonstrate the potential for TSTx to be an integral component of combination therapies for a wide range of advanced solid tumors.

In September 2021, the United States Food and Drug Administration (“FDA”) granted Orphan Drug Designation (“ODD”) to IMX-110 for the treatment of soft tissue sarcoma. If a product that has ODD subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years (except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity).

(Note: Immix Biopharma upsized its IPO at pricing on Dec. 15, 2021, to 4.2 million shares, up from 3.82 million in the prospectus, and priced the IPO at $5 – the bottom of its $5-to-$6 price range – to raise $21 million.)
