Exelixis and Cybrexa Therapeutics Establish Exclusive Collaboration Providing Exelixis the Right to Acquire CBX-12, a Potential First-in-Class Peptide-Drug Conjugate of Exatecan

On November 1, 2022 Exelixis, Inc. (Nasdaq: EXEL) and Cybrexa Therapeutics (Cybrexa) reported that the companies have entered into an exclusive collaboration agreement providing Exelixis the right to acquire CBX-12 (alphalex exatecan), a clinical-stage, first-in-class peptide-drug conjugate (PDC) that utilizes Cybrexa’s proprietary alphalex technology to enhance delivery of exatecan to tumor cells (Press release, Exelixis, NOV 1, 2022, View Source [SID1234622695]). CBX-12 is designed to increase the efficacy and reduce the toxicity of topoisomerase I inhibition by delivering exatecan, a highly potent, second-generation topoisomerase I inhibitor, directly to the tumor cells. This collaboration underscores Exelixis’ commitment to expanding its clinical pipeline building upon its biotherapeutics and targeted drug therapy expertise.

CBX-12 is composed of a pH-Low Insertion Peptide (pHLIP), a linker and exatecan. As an antigen-independent therapy, CBX-12 may have broad utility in patients who are not eligible for antigen-targeted therapies, including monoclonal antibodies and antibody-drug conjugates (ADCs), and has potential for use in combination regimens with other anti-cancer agents and immunotherapies. Data from the ongoing phase 1 trial of CBX-12 in patients with metastatic solid tumors, reported in an oral presentation during a plenary session at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) (ENA) 2022 Symposium on October 28, 2022, demonstrated preliminary anti-tumor activity in a heavily pretreated patient population. This included a complete response in a patient with ovarian cancer.

"This agreement aligns with Exelixis’ goal of acquiring first- or best-in-class clinical-stage assets that may provide differentiated benefits to patients with cancer. Today’s announcement further highlights our ongoing strategy to leverage our balance sheet to gain access to new assets with compelling potential upside in a risk-sharing model, where we can work with partners to further establish proof of concept before investing more heavily," said Michael Morrissey, Ph.D., President & CEO, Exelixis. "Robust preclinical data and initial clinical data from the ongoing phase 1 trial suggest that CBX-12 may provide differentiated clinical benefit in several solid tumors. Similar to our interest in antibody-drug conjugates, we believe this novel peptide-drug conjugate has transformative clinical potential, and this collaboration affords us the opportunity to expand our clinical pipeline with a best-in-class exatecan therapy if additional CBX-12 clinical data demonstrate enhanced safety and efficacy."

Cybrexa’s proprietary alphalex technology is designed to increase the therapeutic index of potent anti-cancer compounds by targeting their delivery to tumor cells, thus reducing systemic exposure and thereby reducing toxicity. Importantly, this targeting is achieved through an antigen-independent mechanism, making the alphalex technology potentially applicable to diverse tumor types and providing a complementary approach to traditional ADCs. The alphalex technology platform utilizes pHLIPs combined with a linker to deliver anti-cancer compounds directly to tumor cells. In the acidic (low pH) tumor microenvironment, the pHLIP forms an alpha-helical structure that inserts itself into and across the tumor cell membrane. It is well established that many tumors have an altered metabolism that results in excretion of lactic acid into the tumor microenvironment, thereby reducing the local pH. The linker is cleaved within the cell, releasing the anti-cancer agent into the cell’s cytoplasm. The alpha-helical structure of the peptide (pHLIP) does not form in the physiologic pH surrounding normal cells, preventing delivery to these cells and reducing toxicity.

"Cybrexa is focused on developing the next generation of cancer therapeutics that specifically target tumors and their underlying biology," said Per Hellsund, President & CEO, Cybrexa. "With its expanding portfolio of biotherapeutics, including ADCs, Exelixis and its partner network have significant and expanding expertise in PDC chemistries and development. Our alphalex PDC technology is an important complement to ADCs and other targeted therapies, and we are excited to bring Exelixis’ insights and resources to the development of CBX-12."

Financial Considerations

Under the terms of the agreement, Exelixis will pay Cybrexa an upfront fee of $60 million in exchange for the right to acquire CBX-12 pending certain Phase 1 results and to fund certain development and manufacturing expenses incurred by Cybrexa to advance an agreed development plan. Cybrexa may also be eligible to receive up to an additional $642.5 million, including development, regulatory, and commercial milestone payments, as well as a fee for the acquisition of CBX-12 upon evaluation of a pre-specified clinical data package.

Please see Exelixis’ disclosure in today’s Form 10-Q filed with the Securities and Exchange Commission for additional details of the terms of the collaboration agreement.

"Exelixis focused its efforts toward the progress and expansion of our clinical and early-stage pipeline during the third quarter of 2022, fueled by the growing revenues from our cabozantinib franchise," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer, Exelixis. "The team continued to drive strong commercial performance for cabozantinib, resulting in 39 percent year-over-year net product revenue growth for our flagship franchise. The team was also highly active on the business development front evaluating various opportunities and executing on multiple deals, including new option deals with Cybrexa and Sairopa announced today, which highlight our strategic efforts to access clinical- or near-clinical-stage assets that have the potential to be first- or best-in-class medicines and may provide differentiated benefits to patients with cancer."

Dr. Morrissey continued: "In addition, we achieved key clinical milestones, including presenting detailed results from our pivotal COSMIC-313 clinical trial and dose-escalation data from the phase 1b STELLAR-001 trial of XL092 at the ESMO (Free ESMO Whitepaper) 2022 Congress, as well as sharing the first clinical update from our phase 1 XB002 tissue factor ADC program at the 34th ENA Symposium in October. I’d like to thank the entire Exelixis team for their continued hard work and dedication in the third quarter as we made significant progress in commitment of the patients we serve."

Third Quarter 2022 Financial Results

Total revenues for the quarter ended September 30, 2022 were $411.7 million, as compared to $328.4 million for the comparable period in 2021.

Total revenues for the quarter ended September 30, 2022 included net product revenues of $366.5 million, as compared to $263.1 million for the comparable period in 2021. The increase in net product revenues was primarily due to an increase in sales volume, which was partially offset by increases in discounts and allowances, primarily from an increase in chargebacks related to the 340B Drug Pricing Program.

Collaboration revenues, composed of license revenues and collaboration services revenues, were $45.3 million for the quarter ended September 30, 2022, as compared to $65.3 million for the comparable period in 2021. The decrease in collaboration revenues was primarily related to decreases in the recognition of milestone-related revenues and development cost reimbursements earned, which was partially offset by higher royalty revenues for the sales of cabozantinib outside of the U.S. generated by Exelixis’ collaboration partners, Ipsen Pharma SAS (Ipsen) and Takeda Pharmaceutical Company Limited (Takeda).

Research and development expenses for the quarter ended September 30, 2022 were $198.8 million, as compared to $163.4 million for the comparable period in 2021. The increase in research and development expenses were primarily related to increases in clinical trial costs, personnel expenses, consulting and outside services expenses, and stock-based compensation expense, which were partially offset by a decrease in other development costs.

Selling, general and administrative expenses for the quarter ended September 30, 2022 were $115.0 million, as compared to $101.6 million for the comparable period in 2021. The increase in selling, general and administrative expenses was primarily related to increases in personnel expenses, business technology initiatives, and rent and utilities expenses.

Provision for income taxes for the quarter ended September 30, 2022 was $18.8 million, as compared to $15.1 million for the comparable period in 2021, primarily due to an increase in pre-tax income.

GAAP net income for the quarter ended September 30, 2022 was $73.2 million, or $0.23 per share, basic and diluted, as compared to GAAP net income of $38.2 million, or $0.12 per share, basic and diluted, for the comparable period in 2021.

Non-GAAP net income for the quarter ended September 30, 2022 was $102.0 million, or $0.32 per share, basic and $0.31 per share, diluted, as compared to non-GAAP net income of $64.5 million, or $0.20 per share, basic and diluted, for the comparable period in 2021.

Cash, cash equivalents, restricted cash equivalents and investments were $2.1 billion at September 30, 2022, as compared to $1.9 billion at December 31, 2021.

Non-GAAP Financial Measures

To supplement Exelixis’ financial results presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Exelixis presents non-GAAP net income (and the related per share measures), which excludes from GAAP net income (and the related per share measures) stock-based compensation expense, adjusted for the related income tax effect for all periods presented.

Exelixis believes that the presentation of these non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. In particular, Exelixis believes that these non-GAAP financial measures, when considered together with its financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare Exelixis’ results from period to period, and to identify operating trends in Exelixis’ business. Exelixis has excluded stock-based compensation expense, adjusted for the related income tax effect, because it is a non-cash item that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented. Exelixis also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate its business and to make operating decisions.

These non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Exelixis encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP financial information and the reconciliation between these presentations, to more fully understand Exelixis’ business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.

Cabozantinib Highlights

Cabozantinib Franchise Net Product Revenues and Royalties. Net product revenues generated by the cabozantinib franchise in the U.S. were $366.5 million during the third quarter of 2022, up 6% over the prior quarter, comprised of net product revenues of $361.4 million from CABOMETYX (cabozantinib) and $5.1 million from COMETRIQ (cabozantinib). In the third quarter of 2022, global cabozantinib franchise net product revenues generated by Exelixis and its partners were almost $500 million. Exelixis earned $30.3 million in royalty revenues during the quarter ended September 30, 2022, pursuant to collaboration agreements with its partners, Ipsen and Takeda.

Detailed Results from Phase 3 COSMIC-313 Pivotal Trial in Patients with Previously Untreated Advanced Renal Cell Carcinoma (RCC) Presented at the 2022 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress. In September, Exelixis presented detailed results from the pivotal phase 3 COSMIC-313 trial evaluating the triplet combination of cabozantinib, nivolumab and ipilimumab versus the combination of nivolumab and ipilimumab in patients with previously untreated advanced intermediate- or poor-risk RCC, at the 2022 ESMO (Free ESMO Whitepaper) Congress. The data included detailed results of the primary endpoint of progression-free survival (PFS) demonstrating a positive PFS benefit for the triplet combination of cabozantinib, nivolumab and ipilimumab compared to the combination of nivolumab and ipilimumab, as well as encouraging objective response rates in the PFS intent-to-treat population. The safety profile observed in the trial was reflective of the known safety profiles for each single agent as well as the combination regimens used in this study. Previously, in July, Exelixis announced that COSMIC-313 met its primary endpoint, demonstrating significant improvement in PFS at the primary analysis. At a prespecified interim analysis for the secondary endpoint of overall survival (OS), the combination of cabozantinib, nivolumab and ipilimumab did not demonstrate a significant benefit over the combination of nivolumab and ipilimumab. Therefore, the trial will continue to the next analysis of OS.

Pipeline Highlights

Presentation of Dose-Escalation Results from Phase 1b STELLAR-001 Trial Evaluating XL092 Monotherapy and in Combination with Atezolizumab in Patients with Advanced Solid Tumors at the 2022 ESMO (Free ESMO Whitepaper) Congress. In September, Exelixis presented results from the dose-escalation stage of STELLAR-001, an ongoing phase 1b trial evaluating XL092 as a single agent and in combination with atezolizumab in patients with locally advanced or metastatic solid tumors. The data showed that XL092 demonstrated preliminary clinical activity similar to that observed with cabozantinib in phase 1 across a range of solid tumors and dose levels, with a manageable safety profile. Of note, both single-agent XL092 and XL092 in combination with atezolizumab demonstrated encouraging efficacy and safety in a heavily pretreated patient population, including clear cell RCC patients previously treated with cabozantinib. Tumor reduction was seen in a majority of patients along with a high disease control rate. The maximum tolerated dose was determined to be 120 mg, and the recommended dose for the expansion stage is 100 mg for both single-agent XL092 and XL092 in combination with atezolizumab. The cohort-expansion stage of the study is currently ongoing and enrolling patients across multiple solid tumor types.

Expanded Clinical Trial Collaboration and Supply Agreement with Bristol-Myers Squibb (BMS) to Include Fixed-Dose Combination of Nivolumab and Relatlimab in Combination with XL092 in Phase 1b STELLAR-002 Trial. In October, Exelixis announced the expansion of its June 2021 Clinical Trial Collaboration and Supply Agreement with BMS to include the use of the fixed-dose combination of nivolumab and relatlimab in the ongoing phase 1b STELLAR-002 clinical trial, which is evaluating XL092 in combination with multiple immune checkpoint inhibitors in advanced solid tumors. Relatlimab is a lymphocyte activation gene-3 (LAG-3)-blocking antibody. LAG-3 is an inhibitory immune checkpoint expressed on the surface of T-cells. The STELLAR-002 trial is divided into two parts: a dose-escalation stage and a cohort-expansion stage. Enrollment and dosing in the dose-escalation portion of STELLAR-002 is ongoing. The dose-escalation stage will determine the recommended dose in patients with advanced solid tumors for each of the combination therapy regimens, including: XL092 and nivolumab; XL092, nivolumab and ipilimumab; and XL092 and the fixed-dose combination of nivolumab and relatlimab. The novel triplet combination of XL092 and the fixed-dose combination of nivolumab and relatlimab has the potential to be used in multiple expansion cohorts.

Presentation of Initial Dose-Escalation Results from the First-in-Human Phase 1 JEWEL-101 Trial Evaluating XB002 in Patients with Advanced Solid Tumors at the 34th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) (ENA) Symposium. In October, Exelixis presented promising initial results from the ongoing dose-escalation stage of JEWEL-101, a phase 1 study evaluating Exelixis’ XB002 next-generation tissue factor targeting antibody-drug conjugate (ADC), at the 34th ENA Symposium. The data demonstrated that XB002 was well-tolerated across multiple dose levels, with no dose-limiting toxicities observed as of the data cutoff. A pharmacokinetic analysis demonstrated that XB002 exposure increased more than or proportionately to dose increases. XB002 total antibody and intact ADC pharmacokinetics were similar, suggesting XB002 is stable after infusion. Consistent with this, levels of free circulating payload remained low at all dose levels. JEWEL-101 is enrolling patients with advanced solid tumors for which therapies are unavailable, ineffective or intolerable. The dose-escalation stage of the study is currently ongoing and will progress to the cohort-expansion stage once the recommended dose and/or maximum tolerated dose for XB002 have been determined. In the upcoming cohort-expansion stage, the efficacy of XB002 will be further evaluated as a single agent and in combination with nivolumab.

Corporate Updates

Exclusive License Agreement with Ryvu Therapeutics S.A. (Ryvu) to Develop Novel STING Agonist-Based Targeted Cancer Therapies.
