On October 3rd, 2018 RXi Pharmaceuticals Corp. (NASDAQ:RXII) announced it had closed its $15 million public underwriting. 3.725 million shares were issued at $0.70 per share and 17.702 million prefunded warrants were issued at $0.69 per share with a $0.01 exercise price. 21.427 million seven year warrants were also issued with an exercise price of $0.70.
Our initial thesis for RXi Pharmaceuticals called for monetization of the dermal and occular assets mid-year 2018, which would have allowed the company to avoid major share issuances and draw from the Lincoln Park Purchase Agreement to satisfy any near term funding needs. However, the sales process for these assets has taken longer than anticipated, leaving the company with insufficient funds to continue operations into 2019. RXi has decided to raise capital through the issuance of shares and warrants in an effort to continue its pre-clinical work for RXI-762 and maintain a strong negotiating position for the sale of Samcyprone and RXI-109. The October 3rd capital raise is sufficient along with estimated cash on the balance sheet to fund research preclincal and Phase I studies for RXI-762.
Despite the difficulties on the financing side of the equation, RXi continues to develop its immuno-oncology program. On September 26, 2018, RXi presented a poster highlighting the use of sd-rxRNA in natural killer (NK) cells for use in hematological cancers. The poster illustrated the ability of the ability of the immune effector cells to take up sd-rxRNA without the need for transfection reagents and downregulated Casitas B-lineage Lymphoma-b (Cbl-b) gene, which is a negative regulator of T-cell activation. This is important because NK cells can recognize and kill cancer cells without prior sensitization. They are the first line of defense against cancer cells but similar to T-cells have inhibitory receptors that sometimes prevent their cytotoxic activity. The use of sd-rxRNA to reduce these receptors will allow a potent anti-cancer response.

The poster also reviewed the viability of sd-rxRNA silencing in the freeze-thaw cycle and found that it was similar to that of cells that had been transfected for 72 hours without the cycle. This ability allows the sd-rxRNA to be used with existing in-development chimeric antigen receptor (CAR) therapy without changing the administration protocol.
The following exhibit is the latest pipeline graphic for RXi, which also includes several of the undisclosed compounds in adoptive cell therapy (ACT) and tumor microenvironment. The lead aset is RXI-762, which seeks to increase the expression of PD-1 in cell based therapies. Earlier stage programs are targeting the immune receptor TIGIT in solid tumors among other checkpoints. Cell differentiation is another program that is seeking to extend the life of modified immune cells so they will work longer.

We adjust our target price to reflect the share and warrant issuance which increases our share balance to 25.8 million. We also add anticipated warrant exercise for total diluted shares of 50.9 million. This adjustment reduces our target price to $2 per share. We highlight the dramatic impact on target price when substantial shares and warrants are issued substantially below the target price. While the enterprise value of the company remains the same, the division of this value among a dramatically larger share base has a negative impact on target price. Our thesis for RXi was based on the receipt of non-dilutive financing from the sale of Phase 2 assets for Samcyprone and RXI-109 which has not yet taken place, resutling in the downward revaluation of our target price.
We are disappointed to see the substantial dilution from the recent share issuance but still see value in sd-rxRNA and the programs that have been advanced to Phase II. We highlight that before the transaction the entirety of the company, including the intellectual property for the sd-rxRNA approach and multiple developed programs in the dermatology and ophthalmology spaces were valued at less than $10 million. Regarding the sale of Samcyprone and RXI-109, it appears that there are a number of interested parties performing due diligence on the dermal and ocular assets; however, the ultimate timing of a sale or whether or not a sale will take place is unclear. We see sufficient cash on the balance sheet to support operations into 2019, providing sufficient time to negotiate a deal and to obtain upfront cash to support the development of the immuno-oncology assets. Based on the share price issuance, we reduce our target price to $2.00 per share.
