Astex Pharmaceuticals and Otsuka announce results of the phase 3 ASTRAL-1 study of guadecitabine (SGI-110) in treatment-naïve AML patients ineligible to receive intense induction chemotherapy

  • Guadecitabine did not meet the co-primary endpoints of complete response (CR) rate or overall survival (OS) in the ASTRAL-1 study
  • Astex continues to focus on completing the phase 3 ASTRAL-2 and ASTRAL-3 studies evaluating the efficacy and safety of guadecitabine in relapsed and refractory acute myeloid leukemia (R/R AML) and relapsed and refractory myelodysplastic syndromes (R/R MDS) and chronic myelomonocytic leukemia (CMML)

Pleasanton, CA and Tokyo, Japan, July 30th, 2018. Astex Pharmaceuticals, a member of the Otsuka group of companies, and Otsuka Pharmaceutical Co. Ltd., announce top-line results from the ASTRAL-1 study evaluating the efficacy and safety of guadecitabine (SGI-110) in adults with previously untreated AML who are not eligible for intensive induction chemotherapy. The study did not meet its co-primary endpoints: complete response (CR) rate (p>0.04), and overall survival (OS) (p>0.01) as per the protocol analysis plan, compared with the control arm of physician’s choice of azacitidine, decitabine, or low dose cytarabine. Evaluation of the study’s secondary endpoints and safety data is ongoing. The full data will be presented at an upcoming scientific meeting.

The company continues to focus on completing the ongoing global phase 3 ASTRAL-2 and ASTRAL-3 studies evaluating guadecitabine in the treatment of relapsed and refractory AML and relapsed and refractory MDS and CMML.

“We are disappointed in the outcome of the ASTRAL-1 study,” said Mohammad Azab, Astex’s president and chief medical officer. “The study used very strict criteria of ineligibility to receive intensive chemotherapy based on age (over 75 years) or poor performance status (ECOG PS of 2 or 3) or comorbidities, which made it a difficult population to show superior benefit of guadecitabine.” Dr. Azab also added, “ASTRAL-1 is the largest global prospective study ever conducted in this specific patient population with low intensity therapy, with 815 patients randomized, of whom about 90% were treated with hypomethylating agents or HMAs (guadecitabine, azacitidine, or decitabine). The large body of clinical and genetic data will still provide the medical community with very valuable insights into the role of several prognostic clinical and genetic markers that may influence outcome with HMA treatment. We are extremely grateful to all the patients, physicians and other healthcare professionals, and partner research and manufacturing organizations who contributed to this global effort. We are now looking forward to the completion of the ASTRAL-2 and ASTRAL-3 studies currently actively recruiting in two different indications.”

About Guadecitabine (formerly SGI-110)

Guadecitabine is a next-generation DNA hypomethylating agent.1,2 Guadecitabine was rationally designed to be resistant to degradation by cytidine deaminase, prolonging the exposure of tumor cells to the active metabolite, decitabine, thus ensuring greater uptake of decitabine into the DNA of rapidly dividing cancer cells.3 Guadecitabine, through the action of decitabine, inhibits DNA methyl transferase (DNMT), with the potential to reverse aberrant DNA methylation, an epigenetic change characteristic of many cancer cells that results in silencing of critical genes. This action may restore the expression of silenced tumor suppressor genes and tumor-associated antigens.4 Through this re-expression of silenced genes, guadecitabine may have the potential to sensitize tumor cells to other anticancer agents,5,6,7 including immunotherapeutics,8 as well as re-sensitizing cancer cells previously resistant to chemotherapeutics.7

Guadecitabine is currently being studied in two additional phase 3 studies:

  • ASTRAL-2: A randomized, open-label study in leukemia patients with relapsed or refractory acute myeloid leukemia (AML) following intensive chemotherapy. See www.clinicaltrials.gov NCT02920008.
  • ASTRAL-3: A randomized, open-label study in myelodysplastic syndromes (MDS) or chronic myelomonocytic leukemia (CMML) after failure of treatment with azacitidine, decitabine, or both. See www.clinicaltrials.gov NCT02907359.

In addition, guadecitabine is being evaluated in over twenty investigator and company-sponsored trials in other hematological malignancies and in solid tumors, both as a single agent, and in combination with chemotherapy or immunotherapy.

Guadecitabine was designed to be administered subcutaneously as a low-volume, stable formulation.

About the ASTRAL-1 Study

The ASTRAL-1 study evaluated the efficacy and safety of guadecitabine (formerly SGI-110) in adults with previously untreated AML who are not eligible for intensive induction chemotherapy (see www.clinicaltrials.gov NCT02348489). The study is the largest global prospective study ever conducted in this specific patient population, with 815 patients randomized from 163 investigator sites in 24 countries worldwide. The study compared guadecitabine, delivered subcutaneously (SC) 60mg/m2/day for 5 days, with physicians’ choice of azacitidine IV or SC 75 mg/m2/day for 7 days, decitabine IV 20 mg/m2/day for 5 days, or low dose cytarabine SC 20 mg bid for 10 days, all administered in 28-day cycles. In addition to the co-primary endpoints of OS and CR, the study evaluated multiple secondary endpoints including progression-free survival; composite CR or CRc (CR + CRi + CRp); overnight stays in hospital; red cell / platelet transfusions; QOL (EQ-5D-5L); duration of response and safety.

About Acute Myeloid Leukemia

AML is the most common form of acute leukemia in adults.9 There were an estimated 21,380 new cases of AML diagnosed in the US in 2017,10 and an estimate of 10,590 patients were projected to have died from AML in the US in 2017.11 Although 60 to 80 percent of AML patients less than 60 years of age may achieve a complete response (CR) with standard intensive induction chemotherapy,12 the outlook for patients 60 years of age or more is significantly worse, with response rates less than 50 percent, cure rates following transplant remaining at less than 10 percent and a median survival of less than one year.12,13,14 These figures have not significantly improved during the last three decades. These patients have few therapeutic options available.15,16 Effective, less toxic therapies are needed for the treatment of AML, particularly for elderly patients where comorbidities and other consequences of aging may often render them ineligible to receive intensive induction chemotherapy, thus denying them a potentially curative transplant.14

Astex Pharmaceuticals Celebrates as Cancer Drug Receives Marketing Approval in Europe

Further Milestone Payment Under Novartis Collaboration as Kisqali® (ribociclib) Receives Approval in Europe as a First-Line Treatment for HR+/HER2- locally Advanced or Metastatic Breast Cancer with an Aromatase Inhibitor
– Kisqali was discovered as part of a strategic research collaboration under which Astex and Novartis Institutes for BioMedical Research (NIBR) scientists jointly developed and optimised the chemical structure of Kisqali, which was then progressed through clinical trials by Novartis
-Marketing approval in Europe follows US marketing approval announced in March 2017

Astex Pharmaceuticals (“Astex”), a pharmaceutical company dedicated to the discovery and development of novel small molecule therapeutics for oncology and diseases of the central nervous system, announced today that its long-standing pharmaceutical collaborator, Novartis, has received marketing approval in Europe for Kisqali® (ribociclib) plus an aromatase inhibitor as a first-line treatment in post-menopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) locally advanced or metastatic breast cancer.

Astex is eligible to receive a milestone payment in respect of the European marketing approval, as well as royalty payments on annual sales of Kisqali, under the drug discovery alliance entered into between Astex and Novartis in 2005.

Approval by the European Commission follows a positive opinion granted in June by the Committee for Medicinal Products for Human Use (CHMP). The positive CHMP opinion was based on superior efficacy and demonstrated safety of Kisqali plus letrozole versus letrozole alone in the pivotal Phase III MONALEESA-2 clinical trial of first-line ribociclib plus letrozole in hormone receptor-positive HER2-negative advanced breast cancer which showed that Kisqali plus letrozole reduced the risk of progression or death by over 44% over letrozole alone at interim analysis. In a subsequent analysis of the trial data, after nearly one year of additional follow-up, Kisqali plus letrozole demonstrated median progression-free survival (PFS) of 25.3 months and 16.0 months for letrozole alone.1 The European approval allows for oncologists to prescribe Kisqali with letrozole, anastrozole or with exemestane and to use their discretion to select the treatment choice they believe is best for each individual patient.

Harren Jhoti, President and CEO of Astex, UK, said, “We are delighted that Novartis has received European approval of Kisqali arising from our productive collaboration with the opportunity to bring a new treatment option to many more women in Europe with advanced breast cancer.”

Astex received a milestone payment following the FDA approval of Kisqali in March 2017 and has received a first royalty payment from Novartis based on sales of Kisqali in the US, and is eligible to receive a milestone payment on approval of an additional regulatory filing in Japan.

Cambridge-based Astex Pharmaceuticals Celebrates as Cancer Drug Receives US Marketing Approval

Further Milestone Payment Under Novartis Collaboration as Kisqali® (ribociclib) Receives FDA approval as a First-Line Treatment for HR+/HER2- Advanced Breast Cancer with an aromatase inhibitor

  • Novartis drug Kisqali® (ribociclib, LEE011) receives marketing approval by the US FDA as a first-line drug for HR+/HER2- advanced breast cancer in combination with an aromatase inhibitor
  • Astex’s scientific expertise was instrumental in the drug’s discovery by solving the crystal structure of the key cancer target CDK4
  • A strategic research collaboration with Novartis under which Astex and Novartis Institutes for BioMedical Research (NIBR) scientists jointly developed and optimised the chemical structure of Kisqali, which was then progressed through clinical trials by Novartis
  • In a clinical trial, Kisqali, plus drug letrozole, has shown significant clinical benefit in all patient subgroups when compared with letrozole alone, for treatment of HR+/HER2- advanced breast cancer

Cambridge, UK, 13th March 2017.  Astex Pharmaceuticals (“Astex”), a pharmaceutical company dedicated to the discovery and development of novel small molecule therapeutics for oncology and diseases of the central nervous system, announced today that its long-standing pharmaceutical collaborator, Novartis, has received US Food and Drug Administration (FDA) marketing approval for Kisqali® (ribociclib, formerly known as LEE011) plus an aromatase inhibitor as a first-line treatment in post-menopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced (metastatic) breast cancer.

Astex is eligible to receive a milestone payment in respect of this FDA marketing approval and on approval of additional regulatory filings in Europe and Japan, as well as royalty payments on annual sales of Kisqali, under the drug discovery alliance entered into between Astex and Novartis in 2005. The partnership was struck to discover cell cycle inhibitors which represented a novel class of compounds that target the mechanisms of cell division in order to prevent or interfere with cancer growth.

Under the collaboration, Astex scientists, based at the company’s research laboratories in Cambridge UK, were responsible for solving the crystal structure of the key cancer target protein CDK4. This was an important scientific breakthrough that no other group had previously been able to achieve, leading to a peer-reviewed publication in PNAS[1].  Working with the Novartis team at the Novartis Institutes for BioMedical Research (NIBR), Cambridge, Mass., USA, Astex then applied its structure-based drug discovery technology, part of its Pyramid™ platform, in the collaboration that led to the discovery of LEE011, (now known as Kisqali) which was then taken forward by Novartis into clinical trials. In total, a team of some 25 Astex scientists were involved in this research program.

Kisqali® (ribociclib) is a selective cyclin-dependent kinase inhibitor, a class of drug that helps slow the progression of cancer by inhibiting two proteins (CDK4 & CDK6) which, when over-activated, can enable cancer cells to grow and divide quickly.

Novartis received the approval under the FDA Breakthrough Therapy Designation and Priority Review programs, based on data from a first-line Phase III trial that met its primary endpoint at interim analysis, due to its superior efficacy compared to letrozole alone. The combination of Kisqali plus letrozole reduced the risk of disease progression or death by 44% over letrozole alone.  There was a sustained separation of the progression free survival curves evident as early as 8 weeks and more than 53% of patients with measurable disease who took Kisqali plus letrozole saw their tumour size shrink by at least 30%. The combination also showed significant clinical benefit in all patient subgroups regardless of disease burden or tumour location[2].

Harren Jhoti, President and CEO of Astex, UK, said, “We’re committed to the fight against cancer and so we are absolutely delighted that Novartis has received this first approval of a cancer drug arising from our productive collaboration. This milestone further validates the power of our Pyramid™ platform and the excellence of our science.  It’s a moment to celebrate when such ground-breaking scientific work results in a new treatment option for women with advanced breast cancer.”

Astex was formed in 1999 in Cambridge, UK, and was a pioneer in the development of fragment-based drug discovery technology.  Backed by leading venture capital firms, including Abingworth, it has established multiple partnerships with major pharmaceutical companies including AstraZeneca, Janssen (Johnson & Johnson) and GSK as well as Novartis to use the Company’s drug discovery platform, Pyramid™, to identify novel small molecule drugs addressing key disease targets.  Today it is a wholly-owned subsidiary of Otsuka Pharmaceutical Co. Ltd., Tokyo, Japan, with a focus on cancer and diseases of the central nervous system.  It employs about 200 staff at its research headquarters in Cambridge UK and its clinical development headquarters in Pleasanton, California, USA.

  • Successful Emulation of IV Decitabine Pharmacokinetics with an Oral Fixed-Dose Combination of the Oral Cytidine Deaminase Inhibitor (CDAi) E7727 with Oral Decitabine, in Subjects with Myelodysplastic Syndromes (MDS): Final Data of Phase 1 Study (Abstract #114). Dr. Guillermo Garcia-Manero et al. Saturday December 3, 10:45 am; Manchester Grand Hyatt, Grand Hall C.

In addition, a poster presentation entitled: Genetic determinants of response to guadecitabine (SGI- 110) in AML (Abstract #1680), Dr. Patricia L. Kropf et al., will be made on Saturday December 3, 9:30 am to 11 am in the San Diego Convention Center, Hall GH.

Data from the guadecitabine Phase 2 study (www.clinicaltrials.gov, NCT01261312) has helped to inform the design of the 800-patient, global Phase 3 study of guadecitabine in adults with previously
untreated AML who are not considered candidates for intensive induction chemotherapy (ASTRAL-1, www.clinicaltrials.gov, NCT02348489), and the newly announced global Phase 3 studies in relapsed / refractory AML (ASTRAL-2, www.clinicaltrials.gov, NCT02920008), and relapsed / refractory MDS or CMML (ASTRAL-3, www.clinicaltrials.gov, NCT02907359). Astex also announced today that enrollment into the ASTRAL-1 study is now complete. The data on ASTX727 being reported at ASH also informed the design of a Phase 2 randomized, cross-over study comparing ASTX727 to decitabine IV in higher risk MDS, which is ongoing.

“The data from these clinical studies helps to validate the development of these agents for the treatment of AML and MDS, potentially providing new treatment options for patients with these
aggressive hematological malignancies” said Mohammad Azab, President and Chief Medical Officer of Astex. “We are delighted to be working with some of the world’s leading experts in the treatment of hematological malignancies in bringing these next-generation therapies to patients.”

 About Guadecitabine (SGI-110)
Guadecitabine is a novel next-generation, small-molecule DNA hypomethylating agent formulated as a single, small-volume, subcutaneous injection. The product was designed to
deliver longer exposure to the active metabolite, decitabine, compared to IV decitabine, and more efficient delivery into key tissues, including the bone marrow. Guadecitabine
demonstrated activity in restoring silenced tumor suppressor gene expression in cancer cells by reversal of DNA methylation and inducing responses in previously treated MDS and AML
patients. Guadecitabine is currently being investigated in multiple clinical trials, including the ASTRAL series of studies and an extensive program of investigational studies in combination
with immunotherapy and other anti-neoplastic agents, for the treatment or a range of hematological malignancies and solid tumors.

About ASTX727
ASTX727 is a unique fixed-dose combination of the hypomethylating agent decitabine, the active ingredient in Dacogen®, and the novel cytidine deaminase inhibitor, E7727. ASTX727 was
designed to deliver decitabine by oral administration. By inhibiting cytidine deaminase, E7727 inhibits the major mechanism by which decitabine is degraded in the gut, and the combination
therefore permits the efficient oral delivery of decitabine at a low dose. Astex is completing a Phase 2 clinical study of ASTX727 in the treatment of intermediate and high risk myelodysplastic
syndromes (MDS). Guadecitabine and ASTX727 are investigational agents, and efficacy and safety have not been established. There is no certainty that these agents will become commercially available.
