Transcenta Presents First Data from Phase 1 Study of pH-Dependent PDL1 Antibody MSB2311 in Patients with Pre-treated Advanced Solid Tumors and Select Hematological Malignancies

On May 27, 2020 Transcenta Holding Limited ("Transcenta"), a global biotherapeutics company with fully-integrated capabilities in discovery, development and manufacturing of antibody-based therapeutics, reported results reported for the first time from a Phase 1 – study (NCT04272944) of MSB2311, an investigational PDL1 targeting antibody with pH dependent and tumor recycling property developed by Transcenta’s subsidiary Mabspace Biosciences (Suzhou) Co., Ltd, in the treatment of Chinese patients with pre-treated advanced solid tumors and select hematological malignancies (Press release, Transcenta, MAY 27, 2020, View Source [SID1234558586]). Initial results suggest a favorable safety profile across all MSB2311 doses evaluated. Investigators reported that patients achieved durable responses which persisted with one durable beyond 12 months at the time of this press release. The data was published as an abstract (Abstract #e15011) in the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Virtual Scientific Program.

The study enrolled Chinese patients with various types of solid tumors who had relapsed or were refractory to established therapies and had not previously been treated with a PD(L)-1 targeting agents. Patients had received at least 2 prior lines of treatment before starting the dose.

"While the treatment of solid tumors with immunotherapy has significantly advanced over recent years, providing patients with alternative agent with deeper response and better tolerability remains critical," said Professor Lin Shen, the lead investigator from Beijing Cancer Hospital. "Initial findings for MSB2311 in this heavily pre-treated population support further study of this investigational tumor recycling immunotherapeutic."

The study was conducted in two parts: dose escalation (part 1) and dose expansion (part 2). Results of the study showed durable responses among patients with solid tumors (n=18) who were treated with MSB2311 across dose groups, ranging from 3 mg/kg-20 mg/kg every three weeks. At the 20 mg/kg dose (n=12), the objective response rate (ORR) was 33 percent (4/12); responses were deep and persisted. At the time of data cut-off, 75 percent (3/4) of patients who achieved a response remained in the study with an ongoing response. Additional dose expansion with alternative dosing regimen at 10 mg/kg every two weeks of the study is ongoing. In addition, 6 patients with hematological malignancy (three T cell lymphoma and three B cell lymphoma) were tested at 20 mg/kg. One of the three T cell lymphoma patients achieved partial response lasting for 6 weeks.

"We are encouraged by the initial response of heavily pre-treated patients with solid tumors to MSB2311," said Jason Huang, M.D., Senior Vice President, Global Head of Clinical Development, Transcenta Holding. "MSB2311 is an example of one of our innovative antibodies where we look to harness our antibody engineering expertise to advance potentially new options for patients."

In the Phase 1 study, no dose limiting toxicity (DLT) was reported and maximum tolerated dose (MTD) has not been identified. The most common treatment emergent adverse events (TEAEs) ( >10%) included anemia, hypothyroidism, hyperglycemia, hypertriglyceridemia, nausea, vomiting, fatigue, malaise, pyrexia and cough.

About MSB2311

MSB2311 is an investigational pH-dependent humanized antibody targeting PDL1. PDL1 is involved in inhibiting the immune system’s response to fight cancer, and PDL1 is expressed at significantly higher levels in tumor cells of people with solid tumors. MSB2311 employs engineered IgG1 which lacks FcR binding. It binds PDL1 on tumor cells and blocks the interaction of PDL1 and PD1, the receptor on T effector cells. In addition, the binding of MSB2311 to PDL1 results in internalization of MSB2311 and MSB2311 can dissociate from bound PDL1 when enter endosome with pH level lower than pH5.5. This allows MSB2311 to recycle to plasma membrane with the help of FcRn and be reused to bind with PDL1 on another tumor cell. Results from preclinical studies demonstrate that MSB2311 can inhibit tumor growth of PDL1 expressing tumor cells in syngeneic mouse-model.

Novartis Kisqali® shows overall survival benefit in HR+/HER2- advanced breast cancer with consistent findings in patients with more aggressive disease

On May 27, 2020 Novartis reported a new exploratory subgroup analysis of the Phase III MONALEESA-3 and MONALEESA-7 trials, to be presented during the ASCO (Free ASCO Whitepaper)20 Virtual Scientific Program, reinforcing the overall survival (OS) benefit of Kisqali (ribociclib) (Press release, Novartis, MAY 27, 2020, View Source [SID1234558518]). In this subgroup analysis, Kisqali plus endocrine therapy increased OS compared to endocrine therapy alone among women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced or metastatic breast cancer with visceral metastases, consistent with the benefit seen in the overall study populations.

"The analysis, looking across two Phase III trials, supports the use of Kisqali in the first-line setting regardless of menopausal status or metastatic location," said Denise Yardley, MD, Principal Investigator, Sarah Cannon Research Institute. "Patients with visceral metastases generally face worse prognosis and a higher risk for treatment resistance, so the consistent overall survival results with Kisqali combination therapy for these patients is compelling."

In the MONALEESA trials, where Kisqali was studied in premenopausal women in combination with NSAI plus goserelin (MONALEESA-7) and in postmenopausal women in combination with fulvestrant (MONALEESA-3), approximately 60% of the participants had visceral metastases (excluding visceral crisis), reflective of real-world clinical practice. In these patients, Kisqali in combination with endocrine therapy showed a 30% reduction in the risk of death in MONALEESA-7 [median OS of not evaluable (NE) vs. 39.9 months with NSAI plus goserelin; HR= 0.698 (95% CI: 0.462-1.054)] and a 20% reduction in the risk of death in MONALEESA-3 [median OS of 41.0 vs. 39.4 months with fulvestrant; HR=0.804 (95% CI: 0.596-1.083)].

In patients with liver metastases, Kisqali combination therapy showed a 47% reduction in the risk of death in MONALEESA-7 [median OS of NE vs. 33.6 months with NSAI plus goserelin; HR=0.531 (95% CI: 0.321-0.877)] and a 37% reduction in the risk of death in MONALEESA-3 [median OS of 36.1 vs. 24.1 months with fulvestrant; HR=0.629 (95%CI: 0.421-0.942)]. The adverse events were consistent with the overall populations.

"Superior overall survival with Kisqali is proven in two phase III trials, and this subgroup analysis shows that Kisqali could make a difference in survival even among patients with the most aggressive forms of advanced breast cancer," said Susanne Schaffert, PhD, President, Novartis Oncology. "Patients are the inspiration behind everything we do, and we will continue to pursue bold treatment advancements that help reimagine the future for people with cancer in hopes that they can live longer, and better."

Additional Kisqali data presented during the ASCO (Free ASCO Whitepaper)20 Virtual Scientific Program include:

An oral presentation on the largest pooled biomarker dataset of any CDK4/6 inhibitor in advanced breast cancer to date across a targeted panel of approximately 550 genes related to cancer and signaling pathways. The analysis identifies key potential gene alterations and their associations with response or resistance to Kisqali across all three MONALEESA trials4.
Updated results from CompLEEment-1, a Phase IIIb single-arm trial of 3,246 patients in first-line setting evaluating Kisqali plus letrozole in an expanded and diverse population closely resembling real-world clinical practice. Results were consistent with those observed in the MONALEESA trials, including median time to progression 27.1 months (95% CI: 25.7-NE) and overall response rate 43.6% (95% CI: 41.5-45.8%). The most common AEs were neutropenia, nausea and fatigue. Treatment-related AEs led to discontinuation in 12.9% of patients5.
A retrospective study using real-world data assessing the economic burden of neutropenia, the most common adverse event following administration of CDK4/6 inhibitors. Neutropenia was reported in 38 patients (25%) in the palbociclib group and 25 patients (17%) in the Kisqali group. Similar rates of neutropenia were observed for grades 1/2 and 4, however, a numerical difference was observed for grade 3: palbociclib 35% vs. Kisqali 26%6.

Kisqali is approved for use in more than 75 countries around the world, including the United States and European Union member states. Kisqali has shown statistically significant overall survival benefit in two Phase III trials with two distinct patient populations7,8.

About Kisqali (ribociclib)
Kisqali is the CDK4/6 inhibitor with the largest body of first-line clinical trial evidence demonstrating consistent and sustained efficacy compared to endocrine therapy alone. Overall survival results from MONALEESA-7 and MONALEESA-3 were presented at ASCO (Free ASCO Whitepaper) 2019 and ESMO (Free ESMO Whitepaper) 2019 respectively, demonstrating Kisqali plus endocrine therapy significantly extends life in pre/perimenopausal or postmenopausal women with HR+/HER2- advanced breast cancer. Overall survival follow-up is ongoing for the Phase III MONALEESA-2 trial.

Kisqali was initially approved by the US Food and Drug Administration (FDA) in March 2017 and by the European Commission (EC) in August 2017, as initial endocrine-based therapy for postmenopausal women with HR+/HER2- locally advanced or metastatic breast cancer in combination with an aromatase inhibitor based on findings from the pivotal MONALEESA-2 trial. Kisqali in combination with an aromatase inhibitor was approved for the treatment of pre-, peri- or postmenopausal women as initial endocrine based therapy, and also indicated for use in combination with fulvestrant as both first- or second-line therapy in postmenopausal women by the FDA in July 2018 and by the EC in December 2018. Regulatory filings are underway with other health authorities worldwide.

Novartis is continuing to reimagine cancer by investigating Kisqali in early breast cancer. The NATALEE study is a Phase III clinical trial of Kisqali with endocrine therapy in the adjuvant treatment of HR+/HER2- early breast cancer being conducted in collaboration with Translational Research In Oncology (TRIO).

Kisqali was developed by the Novartis Institutes for BioMedical Research (NIBR) under a research collaboration with Astex Pharmaceuticals.

We’ve taken a bold approach to our research by including patient populations often neglected in clinical trials, identifying new pathways or mutations that may play a role in disease progression and developing therapies that not only maintain, but also improve, quality of life for patients. Our priority over the past 30 years and today is to deliver treatments proven to improve and extend lives for those diagnosed with advanced breast cancer.

Indication
KISQALI (ribociclib) is a prescription medicine used in combination with an aromatase inhibitor for the treatment of pre/perimenopausal or postmenopausal women with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced or metastatic breast cancer, as initial endocrine-based therapy; or fulvestrant for the treatment of postmenopausal women with HR+/HER2- advanced or metastatic breast cancer, as initial endocrine-based therapy or following disease progression on endocrine therapy.

Important Safety Information
KISQALI can cause severe or life-threatening inflammation of the lungs. Patients should tell their health care provider right away if they experience breathing problems or chest pains. KISQALI can cause a heart problem known as QT prolongation. This condition can cause an abnormal heartbeat and may lead to death. KISQALI is not indicated for concomitant use with tamoxifen due to an increased risk of QT prolongation. Patients should tell their health care provider right away if they have a change in their heartbeat (a fast or irregular heartbeat), or if they feel dizzy or faint. KISQALI can cause serious liver problems. Patients should tell their health care provider right away if they get any of the following signs and symptoms of liver problems: yellowing of the skin or the whites of the eyes (jaundice), dark or brown (tea-colored) urine, feeling very tired, loss of appetite, pain on the upper right side of the stomach area (abdomen), and bleeding or bruising more easily than normal. Low white blood cell counts are very common when taking KISQALI and may result in infections that may be severe. Patients should tell their health care provider right away if they have signs and symptoms of low white blood cell counts or infections such as fever and chills.

Before taking KISQALI, patients should tell their health care provider if they are pregnant, or plan to become pregnant as KISQALI can harm an unborn baby. Females who are able to become pregnant and who take KISQALI should use effective birth control during treatment and for at least 3 weeks after the last dose of KISQALI. Do not breastfeed during treatment with KISQALI and for at least 3 weeks after the last dose of KISQALI.

Patients should tell their health care provider about all of the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements since they may interact with KISQALI. Patients should avoid grapefruit or grapefruit juice while taking KISQALI.

The most common side effects (incidence ≥20%) include white blood cell count decreases, nausea, infections, tiredness, diarrhea, vomiting, hair loss, headache, constipation, rash, and cough. The most common grade 3/4 side effects (incidence >5%) were low neutrophils, low leukocytes, abnormal liver function tests, and low lymphocytes. Abnormalities were observed in hematology and clinical chemistry laboratory tests.
