"After a thorough review of our business operations, development programs and financial resources, a decision was made to focus our efforts on RXi's expanding and promising immuno-oncology programs to accelerate growth and in turn support a return on investment for our shareholders," said Dr.
2018 Business Strategy
RXi will focus development initiatives on novel immuno-oncology therapeutics using its proprietary sd-rxRNA platform. Focusing the development portfolio on Immuno-oncology, with a near term focus on Adoptive Cell Transfer (ACT), will streamline and reduce our quarterly burn-rate for 2018. The Company is aiming to enter the clinic with at least one of our compounds in the next 18 months, targeting a large multi-billion dollar market. This will be achieved by:
- Accelerating the development of RXI-762 and RXI-804, sd-rxRNA compounds targeting PD-1 and TIGIT respectively, for use in the treatment of solid tumors in the context of ACT. Finalize cGMP manufacturing of lead compound.
- Expanding internal development efforts and external collaborations with various existing cell-based approaches, evaluating hematopoietic stem cells, NK cells, TILs, CAR T, TCR and engineered NK cells.
- Developing immuno-oncology targets beyond checkpoint inhibition, i.e. cell differentiation.
- Expanding our research efforts to further demonstrate that our technology is ideally suited to be combined with existing immune effector cell expansion/manufacturing.
Monetize Existing Dermatology and Ophthalmology Franchises:
Relating to the operational review, RXi intends to partner/out-license both its Dermatology and Ophthalmology Franchises. Successfully completing these transactions should provide non-dilutive funding for the Company's focused development path in Immuno-oncology.
Each of these Franchises is comprised of preclinical and clinical-stage assets broadly covered by a robust intellectual property estate. These assets include:
Dermatology
- RXI-109: Phase 2 asset for dermal hypertrophic scarring with positive and statistically significant results addressing a
USD 1-3B market. - RXI-231: Topical cosmetic ingredient in a proprietary formulation with positive results reducing a change of skin tone (pigmentation) triggered by UV (p< 0.04) addressing an estimated USD multi-billion dollar market.
- RXI-185: Cosmetic ingredient that reduces collagenase in in vitro models. May be developed as a cosmetic to improve the appearance of aging skin.
- Samcyprone™: Phase 2 small molecule topical immuno-therapy, with proven efficacy in cutaneous warts with an estimated market size
USD 2-4B . - Access to the self-delivering platform for human therapeutic and diagnostic use in the field of dermatology, providing access to new compounds targeting proteins of relevance for the treatment of skin diseases.
The intellectual property estate for RXi's Dermatology Franchise is comprised of 14 patent families covering: RXI-109, RXI-231, RXI-185 and Samcyprone™. Importantly, this estate includes 18 granted patents broadly covering the sd-rxRNA platform, including RXI-109 in the US,
Ophthalmology
- RXI-109: Phase 1/2 asset with proven safety, using intra-ocular injections, for wet AMD with estimated market size
USD 3-5B . Readouts expected Q1 2018. - Preclinical data package supporting development of RXI-109 by intraocular injection or topical application to the eye for retinal or corneal scarring indications.
- Patented set of sequences against a variety of relevant proteins for targeting ocular disorders. Also, sd-rxRNA compounds against targets which may be involved in retinoblastoma or retinal or corneal scarring.
- Preclinical intra-ocular asset (sd-rxRNA targeting VEGF) with dose-dependent effects and tolerability demonstrated in a rodent model.
- Access to the self-delivering platform for human therapeutic and diagnostic use in the field of ophthalmology, providing ready access to new compounds targeting proteins of relevance for the treatment of ophthalmic diseases.
RXi's Ophthalmology intellectual property estate includes 21 patent families. This estate includes 73 patents covering the composition and methods of use the sd-rxRNA platform and targets and sequences from the OPKO assets, including the use of RXI-109 for the treatment of ocular scarring in the US,

About RXi's self-delivering RNAi (sd-rxRNA) technology platform
sd-rxRNA, RXi's proprietary self-delivering RNAi platform, is a single chemically modified compound with delivery and therapeutic properties built directly into the compound itself. The compound is asymmetrical with a phosphorothioate backbone and contains chemical modifications that provide for efficient cellular uptake and gene silencing. These compounds are potent, stable and specific, and demonstrated to be safe and active in a clinical setting.
RXi's novel sd-rxRNA technology differs from natural and most synthetic RNA interference (RNAi) molecules in that they are chemically modified to allow for efficient internalization of the compounds by cells and silencing of the targeted genes. Importantly, unlike other naked siRNA compounds, delivery of sd-rxRNAs are not limited to a specific cell type. For local delivery and ex vivo cell-based therapeutic applications, our compounds do not require delivery vehicles. This is a significant advantage since delivery vehicles can have related toxicity that affects cell viability. sd-rxRNA has demonstrated nearly 100 percent transfection efficiency with high cell viability in numerous cell types.
