Research abstract

PROJECT SUMMARY     Malignant melanoma is one of the most aggressive types of skin cancer, causing a large  majority of skin-­cancer related deaths worldwide. The combination of anti-­PD-­1 and anti-­CTLA-­4  is FDA approved for metastatic melanoma and shows better efficacy than any single agent  alone. Unfortunately, the incidence of high-­grade immune-­related adverse events (irAEs) due to   anti-­CTLA-­4 is approaching 50%. There is a pressing clinical need to develop therapeutic   agents that may enhance the therapeutic effect of anti-­PD1 therapy without significantly  increasing toxicity in cancer patients.   CureBiotech is aimed to develop an efficacious  intratumoral immunotherapeutic drug that can treat metastatic melanoma by itself and in  combination with anti-­PD1 therapy. Resiquimod is a toll-­like receptors (TLR) 7 and 8 agonist. It  is a second generation imidazoquinoline that is 100 time more potent than imiquimod  (Aldara).   Using a  phase I SBIR grant, CureBiotech has developed two proprietary hydrogel based  injectable formulations for resiquimod. The formulations were designed to confine resiquimod  locally in the tumor to decrease systemic cytokine release symptoms;; and to be penetrate better  fibrotic tumor stroma to allow a stronger host immune response.  Our preliminary data  demonstrates that resiquimod treatment not only inhibited melanoma growth, but also  suppressed lymph node metastasis. Resiquimod increases the number of intra-­tumoral CD45+  leukocytes and enhances the proliferation and function of tumor antigen recognizing CD8+  effector T-­cells. Resiquimod shows synergistic effect in inhibiting melanoma growth when   combined with anti-­PD1 therapy. This SBIR  phase II project is aimed to 1) study PD/PK of the  formulated injectable resiquimod in melanoma mouse models;; 2) optimize  dose/frequency/timing of formulated resiquimod in combination with anti-­PD1 therapy for  melanoma;; 3) perform non-­clinical IND enabling studies using formulated injectable resiquimod.   The deliverables proposed in this SBIR grant represent the jumping stone towards (i)  submission of FDA IND application of an injectable resiquimod formulation and (ii) attracting  private equity funding to support Phase I clinical trial of injectable resiquimod in patients with  metastatic melanoma. CureBiotech has the business development expertise, proper intellectual  property and scientific and personnel capability to achieve these aims quickly and meticulously.   Results from this proposal will lay a solid foundation for FDA IND submission that will ultimately  bring a novel and effective therapy to clinicians and patients in their fight against melanoma.     PROJECT NARRATION  Resiquimod is a powerful immune response modifier that stimulates the body’s own immune  system to attack cancer cells through activation of toll-­like receptors 7/8. In our proposed  project, we will study PD/PK of the formulated injectable resiquimod in melanoma mouse  models;; optimize dose/frequency/timing of formulated resiquimod in combination with anti-­PD1  therapy for melanoma;; and perform non-­clinical IND enabling studies using formulated  injectable resiquimod. CureBiotech is aimed to develop an efficacious intratumoral  immunotherapeutic drug that can treat metastatic melanoma by itself and in combination with  anti-­PD1 therapy.
