About DARZALEX (daratumumab)

DARZALEX (daratumumab) is the first monoclonal antibody (mAb) to receive U.S. Food and Drug Administration approval to treat multiple myeloma and has become a backbone therapy in the treatment of this disease. Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license to develop, manufacture and commercialize daratumumab from Genmab. The subcutaneous formulation of daratumumab (daratumumab and hyaluronidase-fihj) is the first subcutaneous CD38 antibody approved for the treatment of multiple myeloma and the first and only approved treatment for patients with light-chain (AL) amyloidosis. Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high affinity to the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells. Daratumumab triggers a person’s own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death, via apoptosis (programmed cell death). 1,2,3,4,5,6,7

Cellino is on a mission to make stem cell-based regenerative medicines accessible for all eligible patients. Stem cell-derived therapies are poised to prevent, treat, and potentially reverse diseases for which no options are available today or the current standard of care is insufficient. Currently, large scale production of stem cell therapies is challenging due to extensive manual handling, high variability, and expensive manufacturing costs.

Cellino’s next-generation manufacturing platform combines artificial intelligence (AI) and laser technology to automate cell therapy manufacturing to reduce expenditures and overcome scaling limitations. The groundbreaking approach has the potential to reduce production costs by an order of magnitude and expand patient access to cell therapies. Investing in Cellino represents a unique opportunity for Leaps by Bayer to continue to fund the development of next-generation therapies.

"Leaps by Bayer’s mission is to invest in paradigm-shifting technologies that provide long-term answers to some of today’s biggest challenges," said Juergen Eckhardt, MD, Head of Leaps by Bayer. "We believe that artificial intelligence-driven manufacturing is the next important inflection point towards industrializing cell therapies, which undoubtedly are one of the core technologies to advance biotech from treatment to prevention or disease reversal. Cellino’s truly transformative approach to autonomously manufacture stem cell-based therapies fits precisely with our ambition to regenerate lost tissue function for millions of patients."

"Cellino’s software-driven closed loop platform is necessary to industrialize stem cell-derived therapies, which are highly complex in nature," said Nabiha Saklayen, Ph.D., CEO & Co-Founder, Cellino. "We are grateful for the support of new and existing investors who are committed to building an AI-driven future for regenerative medicine. I am honored to lead and grow a team of industry experts across laser physics, deep learning, and stem cell biology who are on a mission to democratize cell therapies for all eligible patients."

Proceeds from the Series A financing will considerably expand Cellino’s software, machine learning, and hardware capabilities for end-to-end manufacturing of both autologous and allogeneic stem cell-based therapies. In addition, Cellino is building a long-term collaboration with the National Institutes of Health (NIH), where senior investigator Dr. Kapil Bharti is leading the first autologous induced pluripotent stem cell (iPSC)-derived clinical trial in the US, to validate Cellino’s manufacturing approach. The company also plans to build early-stage GMP capabilities to support clinical trials.

Cellino’s next-generation process combines label-free imaging, high-speed laser editing, and artificial intelligence (AI) to automate cell reprogramming, expansion, and differentiation in a closed cassette format. Cellino’s approach enables the parallel processing of thousands of patient samples in a single facility, which is vital for scalable manufacturing. Inspired by the semiconductor industry, the company plans to build the first autonomous human cell foundry in 2025.

On January 25, 2022 Sierra Oncology, Inc. (NASDAQ: SRRA), a late-stage biopharmaceutical company dedicated to delivering targeted therapies for rare cancers, reported positive topline data from the pivotal Phase 3 MOMENTUM study—a global, randomized, double-blind clinical trial evaluating momelotinib (MMB) in myelofibrosis patients who are symptomatic and anemic and previously treated with an approved JAK inhibitor (Press release, Sierra Oncology, JAN 25, 2022, View Source [SID1234606769]). The trial met all of its primary and key secondary endpoints.

"These data are extremely exciting and everything we had hoped to see from the trial," said Stephen Dilly, MBBS, PhD, President and Chief Executive Officer of Sierra Oncology. "To achieve statistically significant and clinically important efficacy across all prespecified primary and key secondary endpoints while maintaining platelet counts in such a difficult to treat patient population is remarkable, and a confirmation of the anemia response we identified in the comprehensive review of our previous Phase 3 studies."

Topline data announced based on 195 patients (MMB n = 130; DAN n = 65) include:

Primary Endpoint of Total Symptom Score (TSS) of >50%: 25% in the MMB arm vs. 9% in the control arm (p=0.0095)
Secondary Endpoint of Transfusion Independence (TI): 31% in the MMB arm vs. 20% in the control arm (one-sided p=0.0064; non-inferiority)
Secondary Endpoint of Splenic Response Rate (SRR) >35%: 23% in the MMB arm vs. 3% in the control arm (p=0.0006)
The rate of Grade 3 or worse adverse events in the randomized treatment period was 54% in the MMB arm and 65% in the control arm. Serious treatment emergent adverse events were 35% in the MMB arm and 40% in the control arm.
Mean baseline characteristics for all patients were TSS of 27, Hemoglobin (Hgb) of 8 g/dL and platelet count of 145 x 10 9/L
The full data set will be presented at an upcoming medical meeting
"As a clinician, I am thrilled to see data that confirm the potential of momelotinib as a treatment option for myelofibrosis patients who are anemic or at risk of becoming anemic," said Ruben Mesa, MD, FACP, Executive Director of the Mays Cancer Center, home to UT Health San Antonio, MD Anderson Cancer Center, and co-Principal Investigator of the study. "Anemia of myelofibrosis is strongly correlated with reduced quality of life and a decrease in overall survival. Half of all myelofibrosis patients present with anemia at diagnosis and virtually all become anemic over time. With currently approved therapies being myelosuppressive, it’s wonderful to know that we may soon have such an effective treatment option for these patients."

Barbara Klencke, MD, Chief Medical Officer of Sierra Oncology, stated, "We are committed to working tirelessly to bring momelotinib to patients as quickly as possible. We would like to thank the patients and investigators who participated in this study and look forward to presenting the full data set at an upcoming medical meeting."

About Momelotinib
Momelotinib is a potent, selective and orally bioavailable JAK1, JAK2 and ACVR1 / ALK2 inhibitor under investigation for the treatment of myelofibrosis in symptomatic, anemic patients previously treated with an approved JAK inhibitor. More than 1,200 subjects have received momelotinib since clinical studies began in 2009, including approximately 1,000 patients treated for myelofibrosis, several of whom remain on treatment for over 11 years. Momelotinib is the first and only JAK inhibitor to demonstrate positive data for all key hallmarks of the disease—symptoms, splenic response and anemia.

About Myelofibrosis
Myelofibrosis is a rare blood cancer that results from dysregulated JAK-STAT signaling and is characterized by constitutional symptoms, splenomegaly (enlarged spleen) and progressive anemia. From prior studies with momelotinib, we know approximately half of myelofibrosis patients are moderately to severely anemic when eligible for JAK inhibitor treatment. Furthermore, currently approved JAK inhibitors only address symptoms and splenomegaly and are myelosuppressive. This can lead to worsening anemia, resulting in dose reductions that potentially reduce treatment effect.

About the Pivotal MOMENTUM Clinical Trial
MOMENTUM is a global, randomized, double-blind Phase 3 clinical trial of momelotinib versus danazol in patients with myelofibrosis who were symptomatic and anemic, and had been previously treated with an FDA-approved JAK inhibitor. The study was designed to evaluate the safety and efficacy of momelotinib for the treatment and reduction of the key hallmarks of disease: symptoms, blood transfusions (due to anemia) and splenomegaly (enlarged spleen).

The primary endpoint of the study is Total Symptom Score (TSS) reduction of >50% over the 28 days immediately prior to the end of Week 24 compared to baseline TSS, using the Myelofibrosis Symptom Assessment Form (MFSAF). Secondary endpoints included Transfusion Independence (TI) rate for >12 weeks immediately prior to the end of Week 24 with Hgb levels ≥ 8 g/dL, and Splenic Response Rate (SRR) based on splenic volume reduction of >35% at Week 24. The study enrolled 195 patients based on a planned 180 patients across 21 countries.

Danazol was selected as the treatment comparator given its use to ameliorate anemia in patients with myelofibrosis, as recommended by National Comprehensive Cancer Network (NCCN) and European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) guidelines. Patients were randomized 2:1 (MMB n = 130 and DAN n = 65) to receive either momelotinib or danazol. After 24 weeks of treatment, patients on danazol were allowed to crossover to receive momelotinib. Early cross-over to momelotinib was available for confirmed symptomatic splenic progression.

On January 25, 2022 Checkpoint Therapeutics, Inc. ("Checkpoint") (NASDAQ: CKPT), a clinical-stage immunotherapy and targeted oncology company, reported positive topline results from its registration-enabling clinical trial evaluating the safety and efficacy of its anti-PD-L1 antibody, cosibelimab, administered as a fixed dose of 800 mg every two weeks in patients with metastatic cutaneous squamous cell carcinoma ("cSCC") (Press release, Checkpoint Therapeutics, JAN 25, 2022, View Source [SID1234606768]).

The study met its primary endpoint, with cosibelimab demonstrating a confirmed objective response rate ("ORR") of 47.4% (95% CI: 36.0, 59.1) based on independent central review of 78 patients enrolled in the metastatic cSCC cohort using Response Evaluation Criteria in Solid Tumors version 1.1 ("RECIST 1.1") criteria. The median duration of response ("DOR") had not yet been reached at the data cut-off point (76% of responses are ongoing). Safety data across 201 patients with advanced cancers enrolled and treated in all cohorts of the ongoing study remain consistent with those previously reported, with the majority of treatment-emergent adverse events reported as Grade 1 or 2 in severity. Based on these results, Checkpoint intends to submit a Biologics License Application ("BLA") to the U.S. Food and Drug Administration for cosibelimab later this year, to be followed by a marketing authorization application ("MAA") submission in Europe and additional potential submissions in markets worldwide.

"Most people don’t realize that cutaneous squamous cell carcinoma is the second most common form of skin cancer. While treatable with surgery when caught early, cSCC patients diagnosed with advanced disease that has recurred or metastasized have traditionally faced a poor prognosis and often suffer from painful physical discomfort," commented Professor Philip Clingan, Medical Oncologist at Southern Medical Day Care Centre in Australia and co-principal investigator of the trial. "These impressive results demonstrate that cosibelimab, a novel PD-L1 antibody with a unique two-fold mechanism of action, has the potential to offer physicians a new treatment option that provides compelling efficacy, complemented by a favorable tolerability profile, for patients living with this devastating disease."

James F. Oliviero, President and Chief Executive Officer of Checkpoint, stated, "We are thrilled to report these topline results from our pivotal trial of cosibelimab in metastatic cutaneous squamous cell carcinoma. We believe the strong ORR result is attributable to cosibelimab’s differentiated, two-fold mechanism of action of engaging both T-cells and natural killer cells, while also demonstrating a potential favorable safety profile through its binding to PD-L1, reported in literature as associated with lower rates of severe or worse adverse events as compared to PD-1 therapy. We extend our sincere thanks to the patients, caregivers, investigators and their site staff for their dedication to this trial, particularly during these challenging times globally. We look forward to a detailed presentation of the data at an upcoming medical meeting."

Mr. Oliviero continued, "Upon approval, we intend to position cosibelimab at a lower price point than currently available PD-(L)1 therapies, which we hope will lead to meaningful market share in the U.S. and international markets around the world. We also believe the safety and efficacy profile of cosibelimab could make cosibelimab an attractive agent for use in combination regimens, potentially with drug candidates within our current portfolio, additional molecules we may in-license, and synergistic molecules through potential collaborations, particularly those that can take advantage of the two-fold mechanism of action of cosibelimab."

Additionally, Checkpoint continues to enroll a registration-enabling cohort of patients with locally advanced cSCC, anticipating this potential second indication could be included in the planned initial BLA submission, as well as the global, randomized Phase 3 (CONTERNO) trial of cosibelimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of patients with non-squamous non-small cell lung cancer.

Conference Call Information

Checkpoint will host a conference call today, Tuesday, January 25, 2022, at 8:30 AM ET to discuss the topline results. In order to participate in the conference call, please dial 1-877-269-7756 (U.S.), 1-201-689-7817 (outside of the U.S.).

A live webcast of this conference call will be available on the IR Calendar page under News & Events, located within the Investors section of Checkpoint’s website, View Source, and an audio recording of the conference call will also be available for replay for a period of approximately 30 days following the call.

About Cutaneous Squamous Cell Carcinoma

Cutaneous squamous cell carcinoma (cSCC) is the second most common type of skin cancer in the United States, with an estimated annual incidence of approximately 1 million cases according to the Skin Cancer Foundation. While most cases are localized tumors amenable to curative resection, approximately 40,000 cases will become advanced and an estimated 15,000 people will die from their disease. In addition to being a life-threatening disease, cSCC causes significant functional morbidities and cosmetic deformities based on tumors commonly arising in the head and neck region and invading blood vessels, nerves and vital organs such as the eye or ear.

About Cosibelimab

Cosibelimab (formerly referred to as CK-301) is a potential best-in-class, high affinity, fully-human monoclonal antibody of IgG1 subtype that directly binds to programmed death ligand-1 ("PD-L1") and blocks the PD-L1 interaction with the programmed death receptor-1 ("PD-1") and B7.1 receptors. Cosibelimab’s primary mechanism of action is based on the inhibition of the interaction between PD-L1 and its receptors PD-1 and B7.1, which removes the suppressive effects of PD-L1 on anti-tumor CD8+ T-cells to restore the cytotoxic T cell response. Cosibelimab is potentially differentiated from the currently marketed PD-1 and PD-L1 antibodies through sustained >99% target tumor occupancy to reactivate an antitumor immune response and the additional benefit of a functional Fc domain capable of inducing antibody-dependent cell-mediated cytotoxicity ("ADCC") for potential enhanced efficacy in certain tumor types.
