CAROSELL Clinical Study Programme

Celleron Therapeutics have completed a Phase II clinical study testing the effect of CXD101 in combination with the immune checkpoint inhibitor (ICI) nivolumab in microsatellite stable colorectal cancer (MSS CRC), which typically does not respond to ICI agents alone (the CAROSELL Study). The therapeutic strategy rests on compelling pre-clinical results which provide novel insights into how CXD101 and ICI drugs work together to re-engage recognition of tumours by the immune system, colloquially, to turn ‘cold’ tumours ‘hot’.

The study enrolled 55 previously treated patients from five UK academic centres and demonstrated significant disease control and objective response rates. In addition, the combination therapy was very well tolerated.

This promising data merits further investigation in a large-scale, group comparator, randomised study. As a next step, Celleron Therapeutics has designed a Phase III adaptive study. This will incorporate a composite tumour microenvironment biomarker, which integrates computerised digital analysis of the percentage of stromal cells and T-lymphocytes. As an exploratory endpoint, the clinical study will test whether the artificial intelligence-led digital pathology platform can be used as a basis for enriching patients that respond to CXD101 in combination with ICIs to MSS CRC patients.

Professor David Kerr, Co-founder and Chief Medical Officer of Celleron Therapeutics, commented: "The inclusion of this digital pathology biomarker platform in our CAROSELL 2 clinical study design is exciting and a superb example of how Celleron Therapeutics can deploy its precision medicine platforms to potentially improve and enhance the lives of patients suffering from colorectal cancer. It is our hope that that our biomarker platform can also be validated in other tumour types moving forward."

About Colorectal Cancer

Colorectal cancer is the second most common tumour type in women, and the third most common in men. The approximate 5-year survival rate for colorectal cancer patients with advanced (metastatic) disease is 10% in the United States.

Surgery is indicated for localised disease, whilst chemotherapy (eg 5-fluorouracil, capecitabine, oxaliplatin, irinotecan) has been the standard management for patients with metastatic colorectal cancer. Two agents have been approved for third-line management of advanced colorectal cancer, namely regorafenib (Stivarga) and Trifluridine-tipiracil hydrochloride (Lonsurf), but for both, the response rates are low, and toxicity high.

A subset (5%) of colorectal cancers is characterized with deficient DNA mismatch repair. These tumours tend to have a high expression of checkpoint proteins (PD-1 and PD-L1), which interfere with the body’s normal anti-tumour T-cell response. By disabling these proteins, checkpoint inhibitors such as nivolumab allow the immune system to function properly, and T-cells to kill tumour cells.

However, for the greater majority of patients with a normal Mismatch Repair proficient expression, the microsatellite phenotype is stable (MSS), antigen presentation is believed to be much decreased, and the tumour is thus resistant to checkpoint inhibition. Most MSS patients will ultimately relapse or become resistant to chemotherapy. Thus there remains a very significant unmet clinical need to find novel agents, singly and/or in combination, for the treatment of these late-stage patients.

PharmaCyte Biotech Launches Malignant Ascites Program with Commencement of Pivotal Preclinical Study

On November 30, 2021 PharmaCyte Biotech, Inc. (NASDAQ: PMCB), a biotechnology company focused on developing cellular therapies for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box, reported the commencement of a pivotal study to determine if the treatment PharmaCyte uses for locally advanced, inoperable pancreatic cancer—Cell-in-a-Box (CypCaps) combined with the cancer killing prodrug ifosfamide—can also delay the rate of production and accumulation of malignant ascites (Press release, PharmaCyte Biotech, NOV 30, 2021, View Source [SID1234596280]). This is fluid that accumulates in the abdominal cavity from various cancers.

PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner, said, "We are enthusiastic to relaunch our malignant ascites program and resume our work on developing a treatment for malignant ascites. We plan to conduct another preclinical study in Germany with Heidelberg Pharma that mimics an earlier study which showed the production of malignant ascites can be delayed by our cancer treatment. The cancer cells we will be using in the study have been ordered, and the design of the protocol is underway.

"The Chairman of our Medical and Scientific Advisory Board, Dr. Matthias Löhr, is overseeing the study. We will be using the same animal study model that Dr. Löhr used in the earlier study that showed promise."

Malignant ascites is fluid secreted by abdominal tumors which includes liver, breast, colon, stomach, intestine, ovarian and uterine cancers. This fluid contains cancer cells that can seed and form new tumors throughout the abdomen. Malignant ascites accumulates in the abdominal cavity, causing swelling of the abdomen, severe breathing difficulties and extreme pain. It must be removed on a periodic basis, which is painful and costly.

Currently, there is no available therapy that prevents or delays the production and accumulation of malignant ascites. PharmaCyte plans to change the treatment landscape for malignant ascites fluid using its treatment.

"Small cell lung cancer can progress faster than most forms of lung cancer, although new treatment options can prolong life and improve long-term care options," said Luis Paz-Ares, M.D., Ph.D., professor of medicine at Hospital Universitario 12 de Octubre in Madrid, Spain. "Jazz’s collaborative research with Roche will provide much-needed insights into a potentially new small cell lung cancer therapeutic option in the first-line setting. With approximately a quarter million patients diagnosed globally with small cell lung cancer each year – including thousands in the U.S. alone – a new first-line maintenance combination treatment would be a welcome advancement for patients with extensive disease."

"We’ve already witnessed strong clinical demand for Zepzelca as a therapy for metastatic small cell lung cancer patients in the second-line setting," said Rob Iannone, M.D., M.S.C.E., executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals. "This collaboration with Roche marks an opportunity to further study Zepzelca’s safety and efficacy in combination with the PD-L1 inhibitor, Tecentriq, in a pivotal Phase 3 clinical trial, as part of a first-line, standard-of-care, immunotherapy treatment option for patients with extensive-stage small cell lung cancer, a devastating disease for which novel treatments and strategies are needed."

About the IMforte Phase 3 Trial
As part of the IMforte Phase 3, randomized, multicenter maintenance trial, Jazz and Roche will evaluate the efficacy, safety and pharmacokinetics of Zepzelca plus Tecentriq in adults with ES-SCLC following induction therapy with carboplatin, etoposide and atezolizumab. The primary objective is to determine the ability of this new combination to improve outcomes for patients with ES-SCLC, compared with standard-of-care first-line maintenance as measured by progression-free survival and overall survival. The trial is sponsored by Roche and co-funded by Jazz Pharmaceuticals.

If successful, the trial could potentially support an FDA supplemental new drug application for Zepzelca combined with Tecentriq in first-line maintenance ES-SCLC.

Additional information about the trial, including eligibility criteria and a list of clinical trial sites, can be found at: View Source (ClinicalTrials.gov Identifier: NCT05091567).

About Zepzelca (lurbinectedin)
Zepzelca is an alkylating drug that binds guanine residues within DNA. This triggers a cascade of events that can affect the activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in disruption of the cell cycle and eventual cell death.1

Zepzelca is a prescription medicine used to treat adults with small cell lung cancer that has spread to other parts of the body (metastatic) and who have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working. Zepzelca is approved based on response rate and how long the response lasted. Additional studies will further evaluate the benefit of Zepzelca for this use. Zepzelca is not approved as part of a combination therapy or as a first-line maintenance treatment for patients with extensive-stage small cell lung cancer.

About Small Cell Lung Cancer
In the U.S., approximately 13 percent of lung cancers are small cell.2 There are approximately 30,000 to 35,000 patients in the U.S. and 260,000 patients worldwide who are newly diagnosed with small cell lung cancer (SCLC) each year.2,3 The risk for developing SCLC is much higher among current or former tobacco smokers; however, SCLC can also be caused by exposure to secondhand smoke, asbestos, some inhaled chemicals, radiation and air pollution. People with a family history of lung cancer may also be at a higher risk, too.4 SCLC is the most aggressive form of lung cancer and it tends to spread quickly to other parts of the body including the brain, liver and bone.5,6 A large percentage of SCLC patients on treatment briefly achieve a response, although the cancer often returns and is usually more aggressive and resistant to regimens that were previously effective.2

"Relapsed and/or refractory PTCL carries a grim prognosis with limited treatment options. Data from the registration study of HBI-8000 has demonstrated clinically meaningful responses despite the advanced stage of disease and acceptable safety profile to address an important unmet medical need in this patient population", said Dr. Kensei Tobinai, Visiting Scientist of the National Cancer Center Hospital in Japan and medical expert of HBI-8000 Phase 2 study.

The application of the supplemental indication for R/R PTCL is based on data from a Phase 2b study of 55 patients with aggressive PTCL in Japan and Korea. These patients all had advanced disease, refractory or relapsed relative to prior therapies. HBI-8000 40mg orally administered twice weekly resulted in a 46% Objective Response Rate, median Progression-Free Survival of 5.6 months and a median Overall Survival of 22.8 months.

Dr. Mireille Gillings, CEO & Executive Chair of HUYABIO said, "This second regulatory approval for our lead oncology drug, Hiyasta, in Japan expands our drugs’ indications for patients with severe hematologic malignancies. We are looking forward to additional future indications for Hiyasta that will benefit even more patients."

The Kintara treatment arm is also currently actively recruiting at 30 U.S. sites as of November 24, 2021.

The trial, titled GBM AGILE (Glioblastoma Adaptive Global Innovative Learning Environment), is a patient-centered, Phase 2/3 adaptive platform trial evaluating multiple therapies for patients with newly-diagnosed and recurrent GBM. Since January 2021, GCAR has accelerated the pace of clinical site activation with increased awareness in the medical community of Kintara’s arm of the study. GCAR plans to enroll 150-200 patients in the Kintara arm of the study at over 40 sites in the U.S. and Canada with potential to increase this total to 65 clinical trial centers worldwide.

"The Kintara treatment arm joined the GBM AGILE study in January of this year, and is already active at 31 sites in the US and Canada," stated Timothy Cloughesy, M.D., Professor of the Neurology and Molecular and Medical Pharmacology program at the University of California, Los Angeles and Principal Investigator for the GBM AGILE study. "This international clinical site, which we expect to be the first of many international sites, demonstrates the ability of GCAR’s GBM AGILE platform trial to materially accelerate the clinical development timelines for the company."

"The entire Kintara team remains excited by the pace at which our treatment arm is being executed in the study," commented Robert E. Hoffman, Kintara’s Chief Executive Officer. "With 31 sites already active, including our first international site, we are delighted to witness GCAR’s exceptional clinical trial execution capabilities that drew us to participate in this exciting and highly efficient registrational study."

GBM AGILE is an international, innovative platform trial designed to more rapidly identify and confirm effective therapies for patients with GBM through response adaptive randomization and a seamless Phase 2/3 design. The trial, conceived by over 130 key opinion leaders, is conducted under a master protocol allowing multiple therapies, or combinations of therapies, from different pharmaceutical partners to be evaluated simultaneously. With its innovative design and efficient operational infrastructure, data from GBM AGILE may be used as the foundation for a new drug application and biologics license application submissions and registrations to the FDA and other health authorities.
