Data on ARAC published in Nature Communications (IF 17.7)

On August 8, 2022 PDX Pharmaceuticals reported Data on the ARAC (Antigen Release Agent and Checkpoint Inhibitor) technology has been published in Nature Communications (impact factor 17.7) (Press release, PDX Pharmaceuticals, AUG 8, 2022, View Source [SID1234617846]). ARAC is built upon our patented nanoparticle platform capable of co-delivering multiple therapeutic agents, while keeping a small size – similar to the size of a virus – suitable for infusion and tumor accumulation. ARAC co-delivers a polo-like kinase 1 (PLK1) inhibitor and a PD-L1 antibody to generate cancer specific immune responses. In a metastatic lung tumor model, ARAC reduced the effective doses of free drugs (PLK1 inhibitor and PD-L1 antibody) by 5-fold and the effect was mediated by CD8+ T cells. Importantly, ARAC was also effective in lung tumors that were not responsive to the gold standard immunotherapies, which suggests that ARAC may overcome the clinical limitation of low response rates to immunotherapies.

PDX Pharma in collaboration OHSU is further optimizing the second gen ARAC-02, which is ARAC loaded with immune-stimulant CpG to increase the CD8+ T cell repertoire. These three agents were carefully selected based on their roles in cancer and immune pathways. ARAC-02 can attack tumors directly, train the immune system to attack tumors, and prevent tumors from avoiding the immune system’s attack. The project received a perfect score from the NIH review panel and is now funded by a fast track SBIR award from the National Cancer Institute. We are seeking private investment for IND enabling studies of ARAC-02 for lung cancer treatment as well as funding from the Department of Defense’s Breast Cancer Research Program (BCRP) for treating triple negative breast cancer.

"2022 continues to be an outstanding year for Ligand, in particular as royalties from our Pelican Expression Technology platform grow into meaningful revenue contributors," said John Higgins, CEO of Ligand. "The business is enjoying good momentum with numerous positive late-stage developments announced by our partners this past quarter. Financially, the business is doing very well, and we are solidly positioned to spin-off the expanding OmniAb business through a distribution to shareholders and merger with the Avista SPAC expected to close in the fourth quarter of this year."

Second Quarter 2022 Financial Results

Revenue for the second quarter of 2022 was $57.4 million, compared with $84.7 million for the same period in 2021. Royalty revenue increased 108% to $18.0 million due primarily to Kyprolis and sales of products using the Pelican platform. Core Captisol sales for the second quarter of 2022 were $3.3 million, compared with $9.7 million for the same period in 2021. The difference in sales is due to timing of customer orders. Captisol sales related to COVID-19 were $26.2 million for the second quarter of 2022, compared with $52.8 million for the same period in 2021. The difference in sales is due to reduced demand for the pandemic-related treatment. Contract revenue was $9.9 million, lower than the same period last year which included two significant milestones tied to the Pelican platform. Revenue attributable to the OmniAb business for the second quarter of 2022 was $7.3 million, compared with $5.8 million for the prior year period.

Cost of Captisol was $12.4 million for the second quarter of 2022, compared with $30.6 million for the same period in 2021, with the decrease primarily due to lower total sales of Captisol. Amortization of intangibles was $11.8 million for the second quarter of both 2022 and 2021. Research and development expense was $19.1 million for the second quarter of 2022, compared with $16.0 million for the same period in 2021, with the increase primarily due to continued investment in the OmniAb business including facilities and headcount related expenditures associated with the expected spin-off later this year. General and administrative expense was $14.6 million for the second quarter of 2022, compared with $14.7 million for the same period in 2021.

There was no other operating income for the second quarter of 2022, compared with $34.1 million for the second quarter of 2021, which represented a non-cash valuation adjustment to reduce the Pfenex CVR liability due to an expected lower probability of achieving the required milestone under the Pfenex CVR Agreement.

Net loss for the second quarter of 2022 was $(0.9) million, or $(0.05) per share, compared with net income of $30.7 million, or $1.79 per diluted share, for the same period in 2021. Net loss for the second quarter of 2022 included a $(1.9) million net non-cash loss from the value of Ligand’s short-term investments, and net income for the second quarter of 2021 included a $(8.3) million net non-cash loss from the value of Ligand’s short-term investments. Adjusted net income for the second quarter of 2022 was $17.6 million, or $1.03 per diluted share, compared with $28.0 million, or $1.63 per diluted share, for the same period in 2021. Excluding the impact of gross profit, net of tax, for Captisol sales related to COVID-19, adjusted net income for the second quarter of 2022 was $5.7 million, or $0.34 per diluted share, compared with $13.0 million, or $0.76 per diluted share, for the same period in 2021. Please see the table below for a reconciliation of net income/(loss) to adjusted net income.

Ligand repurchased $62.0 million in principal amount of its 2023 Notes for $60.0 million in cash during the second quarter of 2022. As of June 30, 2022, Ligand had cash, cash equivalents and short-term investments of $147.9 million.

Please see the table below for a reconciliation of net income/(loss) to adjusted net income.

2022 Financial Guidance

Ligand is raising 2022 revenue guidance for the combined business and is reaffirming revenue estimated to be attributable to the OmniAb business anticipating the spin-off occurs later this year. Ligand expects 2022 royalties of $62 million to $66 million, Captisol sales of $55 million to $60 million and contract revenue of $52 million to $62 million. These revenue components result in total revenue of $169 million to $188 million for the combined business. Ligand expects that $35 million to $45 million of revenue will be attributable to OmniAb, principally in the contract revenue line.

Of the $55 million to $60 million of expected Captisol sales, Ligand expects approximately $17 million to $19 million to be attributable to core Captisol sales, and the balance to be attributable to treatments for COVID-19. Excluding OmniAb revenue and COVID-related Captisol sales, Ligand expects revenue to be $97 million to $104 million and adjusted earnings per diluted share to be $1.80 to $2.05. Ligand expects the contribution from COVID-related Captisol and the OmniAb business to be between $0.60 and $0.95 per diluted share, resulting in a combined company adjusted earnings per diluted share of $2.40 to $3.00.

Update on the OmniAb Separation Process

On March 23, 2022, Ligand announced the signing of a definitive merger agreement with Avista Public Acquisition Corp. II (APAC) (NASDAQ: AHPA), a publicly traded special purpose acquisition company (SPAC), providing for the spin-off and merger of OmniAb. The combination of OmniAb and APAC is structured to provide a minimum of $130 million in gross cash to the combined company at the time of closing, and up to $266 million in the event of no redemptions by APAC shareholders.

OmniAb will have an initial pre-money equity valuation of $850 million. Ligand intends to distribute 100% of its ownership in OmniAb to Ligand shareholders immediately prior to the business combination with APAC. The transaction is expected to be tax-free to Ligand and its shareholders for U.S. federal income tax purposes. The transaction is expected to close in the fourth quarter of 2022.

Adjusted Financial Measures

The Company reports adjusted net income and adjusted net income per diluted share in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company’s financial measures under GAAP include share-based compensation expense, non-cash interest expense, amortization related to acquisitions and intangible assets, changes in contingent liabilities, mark-to-market adjustments for amounts relating to its equity investments in public companies, excess tax benefit from share-based compensation, gross profit for Captisol sales related to COVID-19, net of tax, transaction costs and others that are listed in the itemized reconciliations between GAAP and adjusted financial measures included at the end of this press release. However, the Company does not provide reconciliations of such forward-looking adjusted measures to GAAP due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation, including adjustments that could be made for changes in contingent liabilities, changes in the market value of its investments in public companies, share-based compensation expense and the effects of any discrete income tax items. Management has excluded the effects of these items in its adjusted measures to assist investors in analyzing and assessing the Company’s past and future core operating performance. Additionally, adjusted earnings per diluted share is a key component of the financial metrics utilized by the Company’s board of directors to measure, in part, management’s performance and determine significant elements of management’s compensation.

"We are incredibly pleased by all of the progress Mersana has made thus far in 2022, as we have continued to build UpRi as a potential foundational medicine in ovarian cancer, achieved key regulatory goals with XMT-1660 and XMT-2056 and entered into two exciting new strategic partnerships," said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. "UpRi’s advancement remains a primary focus for the organization, and we are excited to be approaching enrollment completion in UPLIFT, our potential registrational trial, and to have patient screening in UP-NEXT underway. At the same time, Mersana’s proprietary ADC platforms are allowing us to advance new candidates into the clinic while also enabling significant collaborations with Janssen and GSK. We believe these recent accomplishments have strengthened both our balance sheet and our position as an ADC leader."

Strategic Goals, Recent Developments and Anticipated Milestones

Build Upifitamab Rilsodotin (UpRi), a first-in-class NaPi2b-targeting ADC, into a Foundational Medicine in Ovarian Cancer
Approaching Enrollment Completion in UPLIFT Registration Trial: Mersana expects to complete the enrollment of patients with platinum-resistant ovarian cancer in UPLIFT, the company’s potential registrational clinical trial, around the end of Q3 2022. The trial’s primary endpoint is the confirmed overall response rate (ORR) in approximately 100 NaPi2b high patients.
Initiated Patient Screening in UP-NEXT Trial: Patient screening is now underway in UP-NEXT, a Phase 3 clinical trial of UpRi as monotherapy maintenance following treatment with platinum doublets in recurrent platinum-sensitive ovarian cancer. If successful, UP-NEXT could serve as a post-approval confirmatory trial in the United States, support potential approvals outside of the United States and support UpRi’s expansion into earlier lines of therapy.
Dose Escalating in UPGRADE Combination Trial: UPGRADE, the company’s Phase 1/2 umbrella trial of UpRi in combination with other agents, is currently dose escalating UpRi in combination with carboplatin. Mersana expects to disclose initial interim dose escalation data in Q4 2022, with a primary focus on safety and tolerability.
Build Pipeline of Highly Impactful Cancer Medicines
Cleared IND for XMT-1660: XMT-1660 is a B7-H4-directed Dolasynthen ADC with a precise, target-optimized drug-to-antibody ratio (DAR 6) and Mersana’s clinically validated DolaLock microtubule inhibitor payload with controlled bystander effect. The U.S. Food and Drug Administration (FDA) has cleared Mersana’s Investigational New Drug (IND) application for XMT-1660, and the company plans to initiate a Phase 1 clinical trial of this candidate imminently. This trial will investigate XMT-1660 in a range of B7-H4-expressing tumors with high unmet need, including breast, endometrial and ovarian cancers.
Cleared IND and Announced Orphan Designation for XMT-2056: XMT-2056 is a systemically administered Immunosynthen STING agonist ADC (DAR 8) that is designed to target a novel HER2 epitope and locally activate STING signaling in both tumor-resident immune cells and in tumor cells (a "one-two punch"), providing the potential to treat patients with HER2-high or -low tumors as monotherapy or in combination with standard-of-care agents. The FDA recently cleared Mersana’s IND application for XMT-2056, and the company plans to initiate a Phase 1 clinical trial of this candidate in patients with a range of HER2 expressing tumors, such as breast, gastric and non-small cell lung cancer, in the second half of 2022. The FDA also recently granted orphan drug designation to XMT-2056 for the treatment of gastric cancer.
Build Mersana with Strategic Partners
Announced New Option Agreement with GSK: In a separate press release today, Mersana announced a global collaboration that provides GSK plc (LSE/NYSE: GSK) an exclusive option to co-develop and commercialize XMT-2056. Under the terms of the agreement, Mersana will receive an upfront option purchase fee of $100 million. Mersana also is eligible to receive up to $1.36 billion in the form of an option exercise payment and development, regulatory and commercial milestone payments if GSK exercises its option. Mersana has retained options to profit-share and to co-promote in the United States. If it exercises its profit-share option, Mersana will be eligible to receive tiered royalties on net sales outside of the United States. If Mersana does not elect to profit-share, it is eligible to receive double-digit tiered royalties on global net sales.
