Versant’s Series A investment in Vividion builds on a successful track record of San Diego-based start-ups including Amira Pharmaceuticals, Quanticel Pharmaceuticals, Jecure Therapeutics, Crinetics Pharmaceuticals and multiple spinouts launched from the firm’s San Diego-based Inception Therapeutics Discovery Engine.

"San Diego possesses a world-class academic community for discovery research and access to high-quality entrepreneurs for company creation," said Thomas Woiwode, Ph.D., managing director at Versant and a Vividion board member. "The result is a tremendous environment for venture capital investment."

"The field of chemical proteomics is uniquely positioned to translate modern scientific discoveries in human biology into first-in-class therapeutics for patients suffering from cancer and other debilitating diseases," said Benjamin Cravatt, Ph.D., Gilula Chair of Chemical Biology at the Scripps Research Institute and a co-founder of Vividion.

Vividion represents one of several Versant portfolio companies focused on developing better cancer therapies through discovery platforms for previously intractable drug targets. Since the firm’s initial investment in Vividion in 2017, Versant has launched four other start-ups in this field. Monte Rosa Therapeutics recently completed a successful IPO. Other Versant-created companies in the field include Stablix Therapeutics and two stealth companies, all launched within the past 12 months.

In August 2020, interim analysis data from ORIENT-11 were released in an oral presentation at the IASLC World Conference on Lung Cancer (WCLC) 2020 Virtual Presidential Symposium. These interim data were simultaneously published online by the Journal of Thoracic Oncology.

ORIENT-11 is a randomized, double-blind Phase 3 clinical trial evaluating sintilimab in combination with pemetrexed and platinum chemotherapy compared to placebo in combination with pemetrexed and platinum chemotherapy as a first-line treatment for locally advanced or metastatic nonsquamous NSCLC without sensitizing EGFR mutations or ALK rearrangements. The Journal of Thoracic Oncology manuscript discloses, as of January 15, 2021, with a median follow-up of 22.9 months, the median overall survival (OS) of patients receiving the sintilimab combination was not yet reached. The sintilimab combination demonstrated a sustainable OS benefit (HR=0.60, 95% CI: 0.45-0.79; p=0.0003), and the median OS for those receiving the placebo combination was 16.8 months.

Whole transcriptome sequencing of baseline tumor samples was performed to probe the predictive and correlative biomarkers, showing that high or medium immune cell infiltration was strongly associated with improved progression-free survival (PFS) in the sintilimab combination group. In particular, high MHC class-II presentation pathway expression was significantly correlated with prolonged PFS (HR=0.32, 95% CI: 0.19-0.54; p<0.0001) and OS (HR=0.36, 95% CI: 0.20-0.64; p=0.0005) in the sintilimab combination group.

Professor Li ZHANG, Head of Department of Internal Medicine, Sun Yat-sen University Cancer Center, the primary investigator of ORIENT-11 and the corresponding author of the manuscript, stated, "Sintilimab in combination with pemetrexed and platinum chemotherapy demonstrated a sustainable survival benefit after long-term follow-up in the ORIENT-11 study. These data showed that this sintilimab combination should be further evaluated as front-line therapy for patients with previously untreated, locally advanced or metastatic nonsquamous non-small cell lung cancer without EGFR or ALK genomic tumor aberrations."

Dr. Wei Xu, Vice President of Translational Medicine of Innovent and co- corresponding author of the manuscript, stated, "Immunotherapy based on PD-1 and PD-L1 antibodies has revolutionized clinical practice of treating non-small cell lung cancer. However, the precise patient population who will benefit from immunotherapy-chemotherapy combination treatment is still unclear. We explored the gene expression profile in the tumor microenvironment and found that the infiltration of antigen-presenting cells and high expression of the MHC-II antigen presentation pathway correlated with improved outcomes in patients who received the sintilimab-pemetrexed-platinum chemotherapy combination. This finding contributes to a better understanding of the mechanism of action of the immunotherapy-chemotherapy combination which could help inform selection of suitable patients for future sintilimab studies. Publication of this study in the Journal of Thoracic Oncology is a recognition of the important work by this research team and we will continue to explore new areas in immuno-oncology, with the goal of identifying additional novel approaches to treat cancer in clinical practice."

Dr. Li WANG, Senior VP of Lilly China and Head of Lilly China Drug Development and Medical Affairs Center, stated: "We’re excited to see that the results of ORIENT-11 show sintilimab in combination with pemetrexed and platinum chemotherapy can bring an overall survival benefit to patients with nonsquamous non-small cell lung cancer in the first-line treatment setting. Also, research of the tumor microenvironment is helping scientists find suitable biomarkers as potential targets for cancer treatment. These ORIENT-11 biomarker results published in the Journal of Thoracic Oncology will help us further understand the mechanism of action of this immunotherapy-based combination in order to identify patients who are more likely to respond to treatment."

About the ORIENT-11 Trial

ORIENT-11 is a randomized, double-blind, Phase 3 clinical trial evaluating the efficacy and safety of sintilimab or placebo in combination with pemetrexed and platinum chemotherapy as a first-line treatment for advanced or recurrent non-squamous non-small cell lung cancer (nsqNSCLC) without sensitizing EGFR mutations or ALK rearrangements (ClinicalTrials.gov, NCT03607539). The primary endpoint is progression-free survival (PFS) assessed by Independent Radiographic Review Committee based on RECIST v1.1. The key secondary endpoints include overall survival (OS) and safety profile.

A total of 397 subjects have been enrolled in the ORIENT-11 trial and randomized in a 2:1 ratio to receive either sintilimab 200mg or placebo in combination with pemetrexed and platinum chemotherapy every three weeks for up to four cycles, followed by either sintilimab injection or placebo plus pemetrexed maintenance therapy. The subjects will receive treatment until radiographic disease progression, unacceptable toxicity or any other conditions that require treatment discontinuation. Conditional crossover is permitted.

About Lung Cancer

Globally, lung cancer is the leading cause of cancer death, killing nearly 1.8 million people worldwide each year. In the U.S., lung cancer is the second most common cancer (not counting skin cancer) and the leading cause of cancer death, responsible for nearly 25 percent of all cancer deaths – more than those from colorectal, breast and prostate cancers combined. Non-small cell lung cancer (NSCLC) accounts for approximately 85 percent of all lung cancers, and about 70 percent of those with NSCLC have the nonsquamous subtype. Fifty percent of NSCLC patients present with advanced or metastatic disease at diagnosis.

About Sintilimab

Sintilimab, marketed as TYVYT (sintilimab injection) in China, is an innovative PD-1 inhibitor with global quality standards jointly developed by Innovent and Eli Lilly and Company. Sintilimab is an immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies of sintilimab to evaluate its safety and efficacy in a wide variety of cancer indications, including more than 10 registrational or pivotal clinical trials.

In China, sintilimab has been approved for four indications, including:

The treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy
In combination with pemetrexed and platinum chemotherapy, for the first-line treatment of nonsquamous non-small cell lung cancer
In combination with gemcitabine and platinum chemotherapy, for the first-line treatment of squamous non-small cell lung cancer
In combination with BYVASDA (bevacizumab biosimilar injection) for the first-line treatment of hepatocellular carcinoma
Additionally, Innovent currently has a regulatory submission under review in China for sintilimab for the second-line treatment of squamous non-small cell lung cancer.

Innovent also has two clinical studies of sintilimab that have met their primary endpoints:

In combination with cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil for the first-line treatment of esophageal squamous cell carcinoma
The second-line treatment of esophageal squamous cell carcinoma
In May 2021, the U.S. FDA accepted for review the Biologics License Application (BLA) for sintilimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of nonsquamous non-small cell lung cancer.

Sintilimab was included in China’s National Reimbursement Drug List (NRDL) in 2019 as the first PD-1 inhibitor and the only PD-1 included in the list in that year.

PTX-100 showed an excellent safety profile and exhibited encouraging activity in Phase 1b trial
In the Phase 1b basket trial, PTX-100 demonstrated an impressive safety profile and was well tolerated at the highest dose of 2,000mg/m2. In addition, no serious adverse events (SAEs) related to PTX-100 were observed during the study. Notably, the drug also exhibited clinical benefit in two T cell lymphoma (TCL) patients with aggressive disease that had not responded to 3-5 prior therapies.

The Company is now planning to conduct an expansion cohort study of PTX-100 concentrating on the treatment of TCL with a possibility of subsequent registration study. Currently, the Company anticipates enrolling up to 12 patients with T cell lymphoma (mainly Peripheral T-Cell Lymphoma or PTCL), which represents an area of considerable unmet need.

PTX-200 Phase 1b trial underway: Acute myeloid leukemia (AML)
The PTX-200 AML study is spearheaded by world-renowned leukemia specialist Professor Jeffrey Lancet at Moffitt Cancer Center and Dr Tara Lin at the University of Kansas Medical Center (KUMC).

Initially, PTX-200 was tested for 25 mg/m2. Having proved its safety, the AML study was advanced to a higher dose of to 35 mg/m2. The Company highlighted that the three patients treated with the 35 mg/m2 dose had achieved complete responses in the study so far. Currently, PTX is screening the second cohort at 45 mg/m2.

Moreover, PTX-200 has been granted Orphan Drug Designation (ODD) by the US Food and Drug Administration.

OmniCAR- A universal next-generation CAR-T
Prescient is developing next-generation products in-house. In January 2021, the oncology player disclosed its three OmniCAR programs-

In June, the Company completed another CAR-T milestone with the completion of manufacturing and delivery of crucial components of the OmniCAR platform. In addition, PTX highlighted that the binders against various cancer targets, including CLL-1, CD33, Her2, and EGFRviii, were produced by a US-based leading antibody manufacturer.

Additionally, in-silico evaluation confirmed the non-immunogenic profile of these crucial components. The results demonstrated that OmniCAR’s binding system components – SpyTag and SpyCatcher – have very low immunogenicity, lower than a panel of humanised therapeutic antibodies already approved for human use.

OnmiCAR also offers collaboration and licensing opportunities for third parties via partnerships based on targets, specific constructs as well as cell types.

"In the second quarter of 2021, Exelixis delivered a 59 percent year over year increase in CABOMETYX net product revenue growth and record total revenues, based on the broad adoption of the CABOMETYX and OPDIVO combination regimen as a preferred treatment in first-line renal cell carcinoma," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. "Following this strong commercial performance, we are raising our net product and total revenue guidance for 2021. In parallel, we also made significant progress across our development activities, with the filing of a supplemental New Drug Application for cabozantinib in differentiated thyroid cancer based on the COSMIC-311 study, and announcements of top-line results from both the COSMIC-312 trial in first-line advanced hepatocellular carcinoma and the expanded Cohort 6 of the COSMIC-021 trial in patients with advanced prostate cancer. In addition, on the pipeline front, we broadened the development program of XL092 with a new clinical collaboration with Bristol Myers Squibb and initiated the Phase 1 trial for XB002, our first antibody-drug conjugate. I’d like to thank the entire Exelixis team for a very strong first half of 2021 and look forward to providing further updates on our progress in the second half of the year."

Second Quarter 2021 Financial Results

Total revenues for the quarter ended June 30, 2021 were $385.2 million, compared to $259.5 million for the comparable period in 2020.

Total revenues for the quarter ended June 30, 2021 included net product revenues of $284.2 million, compared to $178.7 million for the comparable period in 2020. The increase in net product revenues was primarily related to an increase in sales volume that was driven by strong uptake for the combination therapy of CABOMETYX (cabozantinib) and OPDIVO (nivolumab) following approval by the U.S. Food and Drug Administration (FDA) in January 2021.

Collaboration revenues, composed of license revenues and collaboration services revenues, were $100.9 million for the quarter ended June 30, 2021, compared to $80.7 million for the comparable period in 2020. The increase in collaboration revenues was primarily related to increases in development cost reimbursements earned, and 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), which was partially offset by a decrease in the recognition of milestone-related revenues.

Research and development expenses for the quarter ended June 30, 2021 were $148.8 million, compared to $114.9 million for the comparable period in 2020. The increase in research and development expenses was primarily related to increases in license and other collaboration costs, personnel expenses and stock-based compensation expense, which was partially offset by decreases in clinical trial costs.

Selling, general and administrative expenses for the quarter ended June 30, 2021 were $98.5 million, compared to $59.8 million for the comparable period in 2020. The increase in selling, general and administrative expenses was primarily related to increases in personnel expenses, marketing costs, corporate giving and stock-based compensation expense.

Provision for income taxes for the quarter ended June 30, 2021 was $28.8 million, compared to $13.9 million for the comparable period in 2020, primarily due to an increase in pre-tax income.

GAAP net income for the quarter ended June 30, 2021 was $96.1 million, or $0.31 per share, basic and $0.30 per share, diluted, compared to GAAP net income of $66.8 million, or $0.22 per share, basic and $0.21 per share, diluted, for the comparable period in 2020.

Non-GAAP net income for the quarter ended June 30, 2021 was $117.9 million, or $0.38 per share, basic and $0.37 per share, diluted, compared to non-GAAP net income of $79.4 million, or $0.26 per share, basic and $0.25 per share, diluted, for the comparable period in 2020. Non-GAAP net income excludes stock-based compensation, adjusted for the related income tax effect.

Cash, cash equivalents, restricted cash equivalents and investments were $1.7 billion at June 30, 2021, compared to $1.5 billion at December 31, 2020.

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 $284.2 million during the second quarter of 2021, up 25 percent over the prior quarter, with net product revenues of $275.6 million from CABOMETYX and $8.6 million from COMETRIQ (cabozantinib). Exelixis earned $24.9 million in royalty revenues during the quarter ended June 30, 2021, pursuant to collaboration agreements with our partners, Ipsen and Takeda.

Announcement of Phase 1b Results from Cohort 6 of COSMIC-021 Trial in Patients with Metastatic Castration-Resistant Prostate Cancer (CRPC). In May, Exelixis announced results from the metastatic CRPC cohort 6 of COSMIC-021, the phase 1b trial of cabozantinib in combination with atezolizumab in patients with locally advanced or metastatic solid tumors. The analysis included 132 patients, 101 of whom had high-risk disease, defined as measurable visceral and/or extra-pelvic lymph node metastases. Based on these promising results, Exelixis intends to discuss the data with the FDA to determine next steps toward a potential regulatory submission for the combination regimen for patients with high-risk metastatic CRPC and plans to present detailed results at a medical meeting in the second half of 2021.

Cabozantinib Presentations at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (ASCO 2021) Demonstrate Consistent Results in Renal Cell Carcinoma (RCC). In June, cabozantinib was the subject of multiple RCC data presentations at ASCO (Free ASCO Whitepaper) 2021, which included: a post-hoc exploratory analysis demonstrating consistent efficacy benefits across subgroups in the phase 3 CheckMate -9ER pivotal trial with CABOMETYX in combination with OPDIVO compared with sunitinib as a first-line treatment for advanced RCC; results from another post-hoc analysis of the CheckMate -9ER trial demonstrating that CABOMETYX in combination with OPDIVO resulted in a statistically significant and clinically meaningful increase in quality-adjusted survival (Q-TWiST) compared with sunitinib; and positive phase 2 results from an investigator-sponsored trial evaluating cabozantinib in combination with nivolumab in patients with advanced or metastatic non-clear cell RCC.

Detailed Results from Phase 3 COSMIC-311 Pivotal Trial of Cabozantinib in Patients with Previously Treated Radioactive Iodine (RAI)-Refractory Differentiated Thyroid Cancer (DTC) Also Presented at ASCO (Free ASCO Whitepaper) 2021. In June, Exelixis and Ipsen announced detailed results from the phase 3 COSMIC-311 pivotal trial of cabozantinib in patients with previously treated RAI-refractory DTC, presented at ASCO (Free ASCO Whitepaper) 2021. Results from the trial, which met the primary endpoint of demonstrating significant improvement in progression-free survival (PFS) assessed by a blinded independent radiology committee, were recently published in The Lancet Oncology and served as the basis for the supplemental New Drug Application (sNDA) submitted to the FDA in June.

Announcement of Top-line Results of Phase 3 COSMIC-312 Pivotal Trial in Patients with Previously Untreated Advanced Hepatocellular Carcinoma (HCC). In June, Exelixis and Ipsen announced that COSMIC-312, the ongoing phase 3 pivotal trial evaluating cabozantinib in combination with atezolizumab versus sorafenib in patients with previously untreated advanced HCC, met one of the primary endpoints, demonstrating significant improvement in PFS at the planned primary analysis. A prespecified interim analysis for the second primary endpoint of overall survival (OS), conducted at the same time as the primary analysis for PFS, showed a trend favoring the combination of cabozantinib and atezolizumab but did not reach statistical significance. The trial will continue as planned to the final analysis of OS; results are anticipated in early 2022. Exelixis plans to present the trial results at a future medical meeting and intends to discuss the results with the FDA to determine next steps toward a potential regulatory submission for the combination regimen for patients with previously untreated advanced HCC.

FDA Accepts sNDA for CABOMETYX for Patients with Previously Treated RAI-Refractory DTC. In August, Exelixis announced that the FDA accepted the company’s sNDA for CABOMETYX as a treatment for patients 12 years and older with DTC who have progressed following prior therapy and are RAI-refractory (if RAI is appropriate). The FDA granted Priority Review designation and assigned a Prescription Drug User Fee Act goal date, or target action date, of December 4, 2021.

Pipeline Highlights

FDA Accepts Investigational New Drug Application (IND) and Phase 1 Trial Initiated for Tissue Factor-Targeting Antibody-Drug Conjugate (ADC) XB002 in Patients with Advanced Solid Tumors. In April, Exelixis announced that the FDA accepted its IND to evaluate the safety, tolerability, pharmacokinetics and preliminary antitumor activity of XB002 in patients with advanced solid tumors, and in June, a phase 1 trial was initiated. As a next-generation tissue factor-targeting ADC, XB002 has the potential for an improved therapeutic index and may provide a favorable safety profile compared with earlier-generation tissue factor-targeting ADCs. Exelixis in-licensed XB002 from Iconic Therapeutics, Inc. in December 2020 under the companies’ May 2019 collaboration agreement.

Exelixis and Bristol Myers Squibb (BMS) Enter Clinical Trial Collaboration and Supply Agreement to Evaluate XL092 in Combination with Immuno-oncology Therapies in Advanced Solid Tumors. In June, Exelixis announced a clinical trial collaboration and supply agreement with BMS for STELLAR-002, a new phase 1b trial evaluating XL092 in combination with immuno-oncology therapies in advanced solid tumors. The objective of the study is to evaluate the safety, tolerability and efficacy of XL092, Exelixis’ novel next-generation tyrosine kinase inhibitor, in combination with: nivolumab; nivolumab and ipilimumab (YERVOY); and nivolumab and bempegaldesleukin, an investigational CD122-preferential IL-2–pathway agonist developed by Nektar Therapeutics (Nektar). The trial is anticipated to begin enrolling patients in the second half of 2021. Nektar will supply bempegaldesleukin to BMS through their existing global development and commercialization collaboration, which is evaluating nivolumab in combination with bempegaldesleukin.

Corporate Updates

Exelixis Expands its Biotherapeutics Portfolio with Acquisition of Anti-Müllerian Hormone Receptor 2 (AMHR2) Program from GamaMabs Pharma SA (GamaMabs). In May, Exelixis entered into an asset purchase agreement with GamaMabs under which Exelixis will, upon the closing of the asset purchase and subject to certain conditions, acquire all rights, title and interest in GamaMabs’ antibody program directed at AMHR2, a novel oncology target with relevance in multiple forms of cancer. Exelixis believes applying its ADC capabilities to GamaMabs’ panel of antibodies against AMHR2 could yield potential additions to the company’s biotherapeutics portfolio.

Exelixis Files Lawsuit to Enforce Its Intellectual Property Rights for CABOMETYX against Abbreviated New Drug Application (ANDA) Filers. In June, Exelixis filed a patent lawsuit against Teva Pharmaceuticals Development, Inc. and Teva Pharmaceuticals USA, Inc. (individually and collectively referred to as Teva), along with Teva Pharmaceutical Industries Limited, following receipt of two Paragraph IV certification notice letters from Teva informing Exelixis that it had filed an ANDA with the FDA requesting approval to market a generic version of CABOMETYX tablets. Teva’s notice letters included a Paragraph IV certification with respect to three of Exelixis’ Orange Book-listed patents: U.S. Patent Nos. 9,724,342 (formulations), 10,034,873 (methods of treatment) and 10,039,757 (methods of treatment), which expire in 2033, 2031 and 2031, respectively. Teva’s notice letter did not provide a Paragraph IV certification against any additional CABOMETYX patents. Exelixis is seeking, among other relief, an order that the effective date of any FDA approval of the ANDA would be a date no later than the expiration of all of U.S. Patent Nos. 9,724,342, 10,034,873 and 10,039,757, the latest of which expires on July 9, 2033, and equitable relief enjoining Teva and Teva Pharmaceutical Industries Limited from infringing these patents.
