Results from the CALM (UCART19 in Advanced Lymphoid Malignancies) Trial

The CALM study (UCART19 in Advanced Lymphoid Malignancies) is an open label, dose-escalation study designed to evaluate the safety, tolerability and anti-leukemic activity of UCART19 in adult patients with R/R B-ALL. Five out seven patients treated achieved molecular remission at Day 28 post UCAR19. Molecular remission is defined by negative minimal residual disease (MRD). MRD is a measurement of the number of residual leukemic cells that remain after treatment.

"These early results for UCART19 are very encouraging both in terms of manageable safety and the impressive complete molecular remission rate in these hard-to-treat adult patients with R/R B-ALL," said Reuben Benjamin, Principal Investigator of the CALM Study and Consultant Hematologist at King’s College Hospital, United Kingdom. "This first cohort explored a lower dose of UCART19 that is approximately one tenth of that used in most autologous CAR-T trials. These results support additional evaluation of UCART19 at varying doses."

Only one Grade 1 cutaneous acute graft versus host disease (GvHD) occurred. No severe neurotoxicity was observed. Cytokine release syndromes (CRS) were mild and manageable except in one patient treated with UCART19 at the first dose level, who developed CRS Grade 4 and neutropenic sepsis leading to death at Day 15.

Results from the PALL (Pediatric Acute Lymphoblastic Leukemia) Trial

The PALL (Pediatric Acute Lymphoblastic Leukemia) study is a phase 1, open label study designed to evaluate the safety and ability of UCART19 to induce molecular remission defined by MRD negativity at Day 28 to enable allogeneic stem cell transplantation in pediatric patients with high-risk R/R B-ALL. Results showed all five children achieved MRD negativity, enabling them to proceed to allogeneic stem cell transplant. Only one Grade 1 cutaneous acute GvHD occurred. No severe neurotoxicity was observed. Cytokine release syndromes were mild in the majority of cases and were all manageable.

Servier is the sponsor of both studies that are active in Europe and the United States.

"We are proud to present the first clinical trial data with UCART19 in patients with heavily pretreated R/R ALL," said Patrick Therasse, MD, PhD, Head of Research and Development-Oncology for Servier. "We believe this innovative, allogeneic CAR T-cell approach could be disruptive to the patient community."

About UCART19

UCART19 is an allogeneic CAR T-cell product candidate being developed for treatment of CD19-expressing hematological malignancies, gene edited with TALEN. UCART19 is initially being developed in adult and pediatric ALL and is currently in Phase I. UCART19 has the potential to overcome the limitation of the current autologous approach by providing an allogeneic, frozen, "off-the-shelf" T cell based medicinal product.

In November 2015, Servier acquired the exclusive rights to UCART19 from Cellectis. Following further agreements, Servier and Pfizer began collaborating on a joint clinical development program for this cancer immunotherapy. Pfizer has been granted exclusive rights by Servier to develop and commercialize UCART19 in the United States, while Servier retains exclusive rights for all other countries.

CEL-SCI recently announced that the study’s Independent Data Monitoring Committee (IDMC) completed its most recent review of the data from all 928 patients enrolled in the study, and recommended continuing the study as there was no evidence of any significant safety questions.

The primary endpoint of the study, a 10% improvement in overall survival of the Multikine treatment regimen plus Standard of Care (SOC) vs. Standard of Care alone, will be determined after a total of 298 deaths have occurred in these two main comparator arms of the study and have been recorded in the study database. The last patient was enrolled in the study in September 2016. Approximately 135 patients were enrolled in the study from 2011 to 2013, about 195 were enrolled in 2014, about 340 in 2015, and about 260 in 2016. The study protocol assumed an overall survival rate of about 55% at 3 years for the SOC treatment group alone.

IDMCs are committees commonly used by sponsors of clinical trials to protect the interests of the patients and the integrity of the study data in ongoing trials, especially when the trials involve patients with life threatening diseases, and when, as in cancer clinical trials, they extend over long periods of time.

On December 12, 2017 Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, reported an update on its clinical development programs for CRS-207, a first-generation proprietary attenuated strain of Listeria that has been engineered to express the tumor-associated antigen mesothelin (Press release, Aduro Biotech, DEC 12, 2017, View Source;p=RssLanding&cat=news&id=2322291 [SID1234522577]). Based on preliminary results from its mesothelioma and ovarian studies, as well as a business and commercial assessment, the company has determined that it will not continue advancement of CRS-207 and will wind down each of its trials in mesothelioma, ovarian and gastric cancer. Aduro will be working closely with investigators to proceed in a manner that is aligned with the best interests of patients still being treated on these studies.

On December 12, 2017 Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) and Puma Biotechnology, Inc. (Nasdaq: PBYI) reported a preclinical research collaboration with Memorial Sloan Kettering Cancer Center (MSK) to explore the combination of Daiichi Sankyo’s investigational antibody drug conjugate DS-8201 and Puma Biotechnology’s irreversible pan-HER tyrosine kinase inhibitor neratinib (NERLYNX) in HER2-mutated or HER2-positive solid tumors (Press release, Daiichi Sankyo, DEC 12, 2017, View Source [SID1234522606]).

A team of scientists led by Maurizio Scaltriti, PhD, and in collaboration with a team of clinical investigators led by Bob Li, MD, will use isogenic models and established patient-derived xenograft models to assess the susceptibility of HER2-mutated or HER2-positive cancers to DS-8201, neratinib and other HER2-targeting therapies, elucidate mechanisms of action and resistance of these various tumor types, and evaluate the potential for synergistic combinations. Daiichi Sankyo and Puma Biotechnology will co-sponsor the research.

"Since early clinical data suggest that DS-8201 may have activity beyond breast and gastric cancers, the archetype HER2-driven tumors, we are interested in studying this asset on a molecular level as well as in combination with other HER2-targeting agents," said Tom Held, Vice President, Global Head, Antibody Drug Conjugate Task Force, Daiichi Sankyo. "In this collaboration, we are examining whether combining DS-8201 and neratinib, with its specific covalent binding to the HER2 receptor and associated increased internalization, is a rational combination therapy strategy to pursue. We are excited to join forces with Memorial Sloan Kettering and Puma to advance the understanding of combining HER2-targeted therapies to potentially treat various forms of HER2-mutated cancer."

"We are pleased to enter into this research collaboration with Memorial Sloan Kettering and Daiichi Sankyo to explore the combination of neratinib and DS-8201," said Alan Auerbach, Puma’s Chief Executive Officer and President. "Combination therapy with agents that address different and complementary pathways, with neratinib targeting the HER2 kinase and DS-8201 providing an innovative targeted delivery of a potent cytotoxic, represents an intriguing approach to the treatment of HER2 mutated tumors and helps to maximize the potential for both agents in treating cancers with a HER2 mutation."

About DS-8201

DS-8201 is the lead product in the ADC Franchise of the Daiichi Sankyo Cancer Enterprise. ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy ("payload") to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells. Designed using Daiichi Sankyo’s proprietary ADC technology, DS-8201 is a smart chemotherapy comprised of a humanized HER2 antibody attached to a novel topoisomerase I inhibitor payload by a tetrapeptide-based linker. It is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload (or chemotherapy) compared to the way chemotherapy is commonly delivered.

DS-8201 is currently in phase 2 clinical development for HER2-positive unresectable and/or metastatic breast cancer resistant or refractory to T-DM1 (DESTINY-Breast01), phase 2 development for HER2-positive advanced gastric resistent or refractory to trastuzumab (DESTINY-Gastric01) and phase 1 development for other HER2-expressing advanced/unresectable or metastatic solid tumors.

DS-8201 has been granted Breakthrough Therapy designation for the treatment of patients with HER2-positive, locally advanced or metastatic breast cancer who have been treated with trastuzumab and pertuzumab and have disease progression after ado-trastuzumab emtansine (T-DM1), and Fast Track designation for the treatment of HER2-positive unresectable and/or metastatic breast cancer in patients who have progressed after prior treatment with HER2-targeted therapies including T-DM1 by the U.S. Food and Drug Administration (FDA). DS-8201 is an investigational agent that has not been approved for any indication in any country. Safety and efficacy have not been established.

"Although the study did not reach its primary endpoint of superiority in survival, we are encouraged by the higher complete remission rate on the sapacitabine-decitabine arm, especially in the subgroup with low white blood cell count; additional analysis of the data should be pursued," said Hagop Kantarjian, M.D., Professor and Chair, Department of Leukemia, The University of Texas MD Anderson Cancer Center, and chair of the study.

"We are pleased to report detailed results of the SEAMLESS study, which as previously announced, did not reach its primary endpoint," said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. "We believe that the subgroup results have defined a patient population for whom the decitabine-sapacitabine regimen may represent an improvement over low intensity treatment by decitabine alone. We plan to discuss the data, the statistical robustness of the subgroup results and the optimal baseline peripheral white blood cell (WBC) cutpoint with European and US regulatory authorities and will provide updates as appropriate. We are grateful to the patients, their families and the investigators for their contributions to this large study. In parallel, we are progressing our other clinical programs in transcriptional regulation with CYC065 and DNA damage response with sapacitabine-seliciclib in biomarker-selected patients with solid tumors, such as those with BRCA mutations or resistance to existing cancer therapies."

Study Design & Intent-to-Treat Results

The randomized, open label, Phase 3 SEAMLESS study enrolled 482 patients, aged 70 years or older, with newly diagnosed AML who were not candidates for or refused intensive therapy at 110 US and EU sites. Patients were stratified by WBC, antecedent hematologic disorder (AHD), and marrow blasts, and randomized 1:1 to receive either intravenous decitabine administered in alternating cycles with oral sapacitabine versus intravenous decitabine alone.

The trial did not meet its primary endpoint of demonstrating statistically significant improvement in overall survival. A higher complete remission (CR) rate, a secondary endpoint, was observed on the decitabine-sapacitabine arm (17% versus 11%). Other endpoints and safety were similar between the arms.

Prespecified Subgroup Analysis

Baseline WBC

In the less than 10,000 WBC subgroup (n=319) a trend towards improved overall survival (median 8.0 versus 5.8 months, HR=0.84 [0.66, 1.06], p=0.14) favoring decitabine-sapacitabine and a significantly higher CR rate (21.0% versus 8.6%, p=0.0017) was achieved on decitabine-sapacitabine.

In the 10,000 or more WBC subgroup (n=163) significantly better overall survival (median 3.8 versus 5.5 months, HR=1.57 [1.12, 2.19], p=0.007) was observed on decitabine. A trend in CR rate (8.3% versus 15.2%, p=0.18) favoring decitabine was observed but it did not reach statistical significance.

Prior AHD

In the subgroup with prior AHD (n=136) a significantly higher CR rate (16.7% versus 5.7%, p=0.0398) was achieved on decitabine-sapacitabine. There was a numerical difference in median survival (6.4 versus 5.0 months, HR=0.85 [0.59, 1.24], p=0.41) favoring decitabine-sapacitabine but overall survival did not reach statistical significance.

In the subgroup without prior AHD (n=346) there was a numerical difference in median survival (5.9 versus 6.7 months, HR=1.08 [0.86, 1.35], p=0.52) favoring decitabine and CR rate (16.6% versus 12.9%) favoring decitabine-sapacitabine but neither reached statistical significance.

Cytogenetics

In the subgroup with other than unfavorable cytogenetics (n=288) there was a numerical difference in median survival (8.2 versus 5.7 months, HR=0.89 [0.69, 1.15], p=0.38) and CR rate (19.9% versus 11.6%, p=0.16) favoring decitabine-sapacitabine but neither reached statistical significance.

In the subgroup with unfavorable cytogenetics (n=194) there was a numerical difference in median survival (3.8 months versus 5.7 months, HR=1.27 [0.94, 1.73], p=0.12) favoring decitabine but overall survival did not reach statistical significance. There was a numerical difference in CR rate favoring decitabine-sapacitabine (12.0% versus 9.6%) but it did not reach statistical significance.

In the subgroup of patients with below 50% and with 50% or higher bone marrow blasts there were no statistically significant differences in overall survival between the arms.

Presentation

The presentation (abstract 891), titled "Results of a Phase 3 Study of Elderly Patients with Newly Diagnosed AML Treated with Sapacitabine and Decitabine Administered in Alternating Cycles," is available on the Cyclacel website at www.cyclacel.com.

About Sapacitabine

Sapacitabine (CYC682), an orally-available nucleoside analogue, is currently being studied in an ongoing, extension of a Phase 1 study evaluating a combination regimen of sapacitabine and seliciclib, a first generation CDK inhibitor. Parts 1 and 2 of the study evaluated approximately 90 patients with advanced cancers. Part 3 is ongoing in patients with BRCA positive, breast, ovarian and pancreatic cancer. Over 1,000 patients with hematological malignancies and solid tumors have received sapacitabine.

About AML

AML is a rapidly progressing cancer of the blood characterized by the uncontrolled proliferation of immature blast cells in the bone marrow. The American Cancer Society estimates there will be approximately 21,380 new cases of AML and approximately 10,590 deaths from AML in the U.S. in 2017. AML is generally a disease of older adults and the median age is about 67 years. Newly diagnosed elderly patients with poor prognostic risk factors typically die within one year.
