Intramuscular ACM-CpG Monotherapy in Patients With Advanced/Metastatic Solid Tumors With Prior Response to Immunotherapy Alone or in Combination With Chemotherapy

ACM-CpG is a CpG-B TLR9 agonist, which in animal models has led to shrinkage and complete disappearance of injected tumors, durable antitumor memory, and growth inhibitory effects on non-injected tumors while intramuscular administration led to durable control of tumors. This Phase I trial will assess the safety and early signs of efficacy of intramuscular injection of ACM-CpG in patients with advanced malignant solid tumors. The overall objectives of this trial are to establish the safety ACM-CpG.
