Oncology. The Company’s strategy is to (i) demonstrate the independent action of single-agent IL PV-10; that is, safety and activity in T cell and non-T cell inflamed tumor types, in high and low tumor mutation burden tumor types, and in other tumor type categories, such as gene mutations, (ii) demonstrate the coordinated induction of multiple immune signaling pathways (i.e., functional ICD), (Snyder et al., Sci Immunol 2019) by IL PV-10 treatment, (iii) demonstrate the functional T cell response generated by IL PV-10 treatment, and (iv) contrast and compare IL PV-10 treatment (i.e., safety, activity, and induced immune response) with that of immune checkpoint blockade (“CB”) and other drug classes in single-agent and IL PV-10-based combination therapy settings.
This strategy may quicken the advancement of single-agent IL PV-10 along a pathway-to-approval in solid tumor cancer indications where there is high unmet need, limited activity from other therapies, and the opportunity to display the immune response from IL PV-10 treatment, such as mNET (NCT02693067). This strategy may also permit the Company to develop and advance a cancer combination therapy involving one or more CB and/or other drug classes along a pathway-to-approval in a disease indication where there is high unmet need, limited activity from standard of care (“SOC”) treatment, and the opportunity to display how IL PV-10 augments clinical response to existing or emerging SOCs, such as mUM (i.e., combination therapy with an anti-CTLA-4 agent and an anti-PD-1 agent) (NCT00986661).
Hematology. The Company and research collaborators are undertaking preclinical work on a potential, systemically-administered, cGMP RBD leukemia treatment and/or cancer vaccine for pediatric patients.
Virology. The Company and research collaborators are undertaking preclinical work on a potential, systemically-administered, cGMP RBD therapy for SARS-CoV-2 and other classes of enveloped and non-enveloped viruses.
Microbiology. The Company and research collaborators are undertaking preclinical work on cGMP RBD therapy for MDR bacteria.
Ophthalmology. The Company and clinical and research collaborators are undertaking preclinical work on potential, topically-administered, cGMP RBD therapy for the treatment of infectious keratitis.
Dermatology. The Company’s strategy is to (i) demonstrate 12-week single-agent administration proof-of-concept (“POC”) for topical PH-10 that includes (a) a preclinical safety study of extended 12-week administration (compared to, previously, four weeks), (b) a clinical mechanism of action study in atopic dermatitis, which would be a “book-end” trial to the already completed clinical mechanism study in psoriasis, (c) Phase 2 randomized controlled trials of topical PH-10 for the treatment of psoriasis and atopic dermatitis that may potentially utilize SOC comparators, and (d) end-of-Phase 2 meetings with the FDA upon the completion of the abovementioned Phase 2 trials, and (ii) expand POC topical PH-10 treatment to include dermatology combination therapy. Our goal for this POC work is to achieve Phase 3 trial-ready status for topical PH-10 in both psoriasis and atopic dermatitis.
