Hypoparathyroidism-Retardation-Dysmorphism Syndrome

WILMINGTON, DE, USA I June 03, 2023 I Positive results from a planned interim analysis of the DUO-O Phase III trial showed that treatment with a combination of LYNPARZA ® (olaparib), IMFINZI ® (durvalumab), chemotherapy and bevacizumab demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) versus chemotherapy plus bevacizumab (control arm) in newly diagnosed patients with advanced high-grade epithelial ovarian cancer without tumor BRCA mutations. Patients were treated with IMFINZI in combination with chemotherapy and bevacizumab followed by IMFINZI, LYNPARZA and bevacizumab as maintenance therapy. These results will be presented today in an oral presentation at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago (Abstract #LBA5506). The combination of LYNPARZA, IMFINZI, chemotherapy and bevacizumab reduced the relative risk of disease progression or death by 37% versus chemotherapy and bevacizumab (hazard ratio (HR) 0.63; 95% CI 0.52-0.76; p <0.0001). Median PFS was 24.2 months versus 19.3, respectively. In the homologous recombination deficiency (HRD)-positive subgroup of patients, LYNPARZA, IMFINZI, chemotherapy and bevacizumab reduced the relative risk of disease progression or death by 51% versus chemotherapy and bevacizumab alone (HR 0.49; 95% CI 0.34-0.69; p <0.0001). Median PFS was 37.3 months versus 23.0, respectively. Professor Philipp Harter, Director, Department of Gynaecology and Gynaecologic Oncology, Evangelische Kliniken Essen-Mitte, Germany, and principal investigator for the trial, said: “The primary aim of first-line treatment of patients with advanced ovarian cancer is long-term control over the disease, but still too many patients progress quickly and face poor clinical outcomes today. Data from the DUO-O trial interim progression-free survival analysis provide evidence for further improvement with olaparib and durvalumab combination versus chemotherapy and bevacizumab alone in patients without tumor BRCA mutations.” Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “These results are an important milestone in our ongoing journey to address unmet need in ovarian cancer. The DUO-O trial demonstrates the potential of combining PARP inhibition with immunotherapy and we look forward to seeing more mature data and key secondary endpoints results.” At a pre-planned exploratory analysis of the HRD-negative subgroup of patients, LYNPARZA, IMFINZI, chemotherapy and bevacizumab reduced the relative risk of disease progression or death by 32% versus chemotherapy and bevacizumab (HR 0.68; 95% CI 0.54-0.86). Median PFS was 20.9 months versus 17.4. At the time of this interim analysis, an additional arm evaluating the combination of IMFINZI, chemotherapy and bevacizumab demonstrated a numerical improvement in PFS which was not statistically significant (HR 0.87; 95% CI 0.73-1.04; p =0.13). At the time of this planned interim analysis, the overall survival (OS) and other secondary endpoints were immature. OS will be formally assessed at a subsequent analysis. Summary of results: DUO-O *Results based on the stratified model **Results based on the unstratified model: HR 0.51 (95% CI 0.36-0.72) The safety and tolerability of these combinations was broadly consistent with that observed in prior clinical trials and the known profiles of the individual medicines. The most common adverse events (AEs) (greater than or equal to 20% of patients) for the combination of LYNPARZA, IMFINZI, chemotherapy and bevacizumab were nausea (57%), anemia (55%), neutropenia (51%), fatigue/asthenia (49%), arthralgia (34%), constipation (30%), diarrhea (30%), thrombocytopenia (28%), hypertension (26%), vomiting (26%), leukopenia (24%), headache (22%), abdominal pain (21%) and hypothyroidism (20%). Grade 3 or higher AEs were neutropenia (31%), anemia (24%), leukopenia (8%), hypertension (7%) and thrombocytopenia (6%). Approximately 65% of patients treated with the combination of LYNPARZA , IMFINZI , chemotherapy and bevacizumab who experienced AEs during chemotherapy and throughout the maintenance phase remained on treatment at the time of data cut-off, compared to 80% of patients in the control arm (chemotherapy plus bevacizumab).

Notes Ovarian cancer Ovarian cancer is one of the most common gynecologic cancers and is the eighth most common cancer in women worldwide with more than 314,000 new patients diagnosed in 2020 and over 207,000 deaths. This number is expected to rise by almost 42% by 2040 to over 445,000 newly diagnosed patients and 314,000 deaths. 1,2,3 Over two-thirds of patients are diagnosed with advanced disease, which can progress quickly, often within two years, diminishing their quality of life despite treatment. Unfortunately, 50-70% of patients with advanced disease die within five years. 4-7 Outcomes are generally worse in patients with homologous recombination deficiency (HRD)-negative disease, where survival at five years is approximately 30%. 5,8 DUO-O DUO-O is a Phase III randomized, double-blind, placebo-controlled, multi-center trial to evaluate the efficacy and safety of IMFINZI in combination with platinum-based chemotherapy and bevacizumab followed by maintenance treatment with IMFINZI and bevacizumab with or without LYNPARZA in newly diagnosed patients with advanced ovarian cancer without tumor BRCA mutations. Patients were randomized 1:1:1 to: Arm 1 (control), induction therapy with platinum-based chemotherapy in combination with bevacizumab and placebo followed by maintenance treatment with bevacizumab plus placebo; Arm 2, induction therapy with platinum-based chemotherapy in combination with bevacizumab and IMFINZI followed by maintenance IMFINZI and bevacizumab plus placebo; or Arm 3, induction therapy with platinum-based chemotherapy in combination with bevacizumab and IMFINZI followed by maintenance IMFINZI and bevacizumab plus LYNPARZA. In all arms, platinum-based chemotherapy was administered every 3 weeks (q3w) for up to 6 cycles, bevacizumab was administered q3w for up to 15 months, IMFINZI or placebo was administered q3w for up to 24 months, and LYNPARZA or placebo was administered twice daily for up to 24 months. The primary endpoint of the trial is progression-free survival (PFS) as assessed by investigator for Arm 3 compared to Arm 1 (control) in the overall trial population which included patients without tumor BRCA mutations and in the subset of these patients with homologous recombination deficiency (HRD)-positive disease. Key secondary endpoints include PFS as assessed by investigator in Arm 2 compared to control, as well as comparisons for overall survival (OS). DUO-O enrolled over 1200 patients across all treatment arms at 179 study locations. For more information about the trial, visit ClinicalTrials.gov . IMFINZI IMFINZI (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses. IMFINZI is the only approved immunotherapy and the global standard of care in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiation therapy based on the PACIFIC Phase III trial. IMFINZI is also approved in the US, EU, Japan, China and many other countries around the world for the treatment of extensive-stage small cell lung cancer (SCLC) based on the CASPIAN Phase III trial. Additionally, IMFINZI is approved in combination with a short course of IMJUDO ® (tremelimumab-actl) and chemotherapy for the treatment of metastatic NSCLC in the US, EU and Japan based on the POSEIDON Phase III trial. In addition to its indications in lung cancer, IMFINZI is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer in the US, EU, Japan and several other countries; in combination with IMJUDO in unresectable hepatocellular carcinoma in the US, EU and Japan; and in previously treated patients with advanced bladder cancer in a small number of countries. Since the first approval in May 2017, more than 200,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, several gastrointestinal cancers and other solid tumors. LYNPARZA LYNPARZA ® (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumors harboring a deficiency in homologous recombination repair (HRR), such as those with mutations in BRCA1 and/or BRCA2 , or those where deficiency is induced by other agents (such as new hormonal agents [NHAs]). Inhibition of PARP with LYNPARZA leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. LYNPARZA is currently approved in a number of countries across multiple tumor types including maintenance treatment of platinum-sensitive relapsed ovarian cancer and as both monotherapy and in combination with bevacizumab for the 1st-line maintenance treatment of BRCA -mutated ( BRCA m) and homologous recombination deficiency (HRD)-positive advanced ovarian cancer, respectively; for germline BRCA -mutated (g BRCA m), HER2-negative metastatic breast cancer (in the EU and Japan this includes locally advanced breast cancer); for g BRCA m, HER2-negative high-risk early breast cancer (in Japan this includes all BRCA m HER2-negative high-risk early breast cancer); for g BRCA m metastatic pancreatic cancer; in combination with abiraterone for the treatment of metastatic castration-resistant prostate cancer (mCRPC) in whom chemotherapy is not clinically indicated (in the EU) and as monotherapy in HRR gene-mutated mCRPC in patients who have progressed on prior NHA treatment ( BRCA m only in the EU and Japan). In China, LYNPARZA is approved for the treatment of BRCA -mutated mCRPC, as a 1st-line maintenance therapy in BRCA -mutated advanced ovarian cancer as well as 1st-line maintenance treatment with bevacizumab for HRD-positive advanced ovarian cancer. LYNPARZA , which is being jointly developed and commercialized by AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada, has been used to treat over 75,000 patients worldwide.

WILMINGTON, Del.--( BUSINESS WIRE )--Positive results from a planned interim analysis of the DUO-O Phase III trial showed that treatment with a combination of LYNPARZA ® (olaparib), IMFINZI ® (durvalumab), chemotherapy and bevacizumab demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) versus chemotherapy plus bevacizumab (control arm) in newly diagnosed patients with advanced high-grade epithelial ovarian cancer without tumor BRCA mutations. Patients were treated with IMFINZI in combination with chemotherapy and bevacizumab followed by IMFINZI, LYNPARZA and bevacizumab as maintenance therapy. These results will be presented today in an oral presentation at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago (Abstract #LBA5506). The combination of LYNPARZA, IMFINZI, chemotherapy and bevacizumab reduced the relative risk of disease progression or death by 37% versus chemotherapy and bevacizumab (hazard ratio (HR) 0.63; 95% CI 0.52-0.76; p <0.0001). Median PFS was 24.2 months versus 19.3, respectively.

The most common adverse events (AEs) (greater than or equal to 20% of patients) for the combination of LYNPARZA, IMFINZI, chemotherapy and bevacizumab were nausea (57%), anemia (55%), neutropenia (51%), fatigue/asthenia (49%), arthralgia (34%), constipation (30%), diarrhea (30%), thrombocytopenia (28%), hypertension (26%), vomiting (26%), leukopenia (24%), headache (22%), abdominal pain (21%) and hypothyroidism (20%). Grade 3 or higher AEs were neutropenia (31%), anemia (24%), leukopenia (8%), hypertension (7%) and thrombocytopenia (6%). Approximately 65% of patients treated with the combination of LYNPARZA , IMFINZI , chemotherapy and bevacizumab who experienced AEs during chemotherapy and throughout the maintenance phase remained on treatment at the time of data cut-off, compared to 80% of patients in the control arm (chemotherapy plus bevacizumab). IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS There are no contraindications for LYNPARZA. WARNINGS AND PRECAUTIONS Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in approximately 1.5% of patients exposed to LYNPARZA monotherapy, and the majority of events had a fatal outcome. The median duration of therapy in patients who developed MDS/AML was 2 years (range: <6 months to >10 years). All of these patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents, including radiotherapy. Do not start LYNPARZA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt LYNPARZA and monitor blood count weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. Discontinue LYNPARZA if MDS/AML is confirmed. Pneumonitis: Occurred in 0.8% of patients exposed to LYNPARZA monotherapy, and some cases were fatal. If patients present with new or worsening respiratory symptoms such as dyspnea, cough, and fever, or a radiological abnormality occurs, interrupt LYNPARZA treatment and initiate prompt investigation. Discontinue LYNPARZA if pneumonitis is confirmed and treat patient appropriately. Venous Thromboembolism (VTE): Including severe or fatal pulmonary embolism (PE) occurred in patients treated with LYNPARZA. In the combined data of two randomized, placebo-controlled clinical studies (PROfound and PROpel) in patients with metastatic castration-resistant prostate cancer (N=1180), VTE occurred in 8% of patients who received LYNPARZA, including pulmonary embolism in 6%. In the control arms, VTE occurred in 2.5%, including pulmonary embolism in 1.5%. Monitor patients for signs and symptoms of venous thrombosis and pulmonary embolism, and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated. Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, LYNPARZA can cause fetal harm. Verify pregnancy status in females of reproductive potential prior to initiating treatment. Females Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for 6 months following the last dose. Males Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of LYNPARZA and to not donate sperm during this time.

The most common adverse reactions (occurring in ≥20% of patients with uHCC) were rash, diarrhea, fatigue, pruritus, musculoskeletal pain, and abdominal pain. The safety and effectiveness of IMFINZI and IMJUDO have not been established in pediatric patients. Please refer to the full Prescribing Information for important dosage modification and management information specific to adverse reactions. Notes Ovarian cancer Ovarian cancer is one of the most common gynecologic cancers and is the eighth most common cancer in women worldwide with more than 314,000 new patients diagnosed in 2020 and over 207,000 deaths. This number is expected to rise by almost 42% by 2040 to over 445,000 newly diagnosed patients and 314,000 deaths. 1,2,3 Over two-thirds of patients are diagnosed with advanced disease, which can progress quickly, often within two years, diminishing their quality of life despite treatment. Unfortunately, 50-70% of patients with advanced disease die within five years. 4-7 Outcomes are generally worse in patients with homologous recombination deficiency (HRD)-negative disease, where survival at five years is approximately 30%. 5,8 DUO-O DUO-O is a Phase III randomized, double-blind, placebo-controlled, multi-center trial to evaluate the efficacy and safety of IMFINZI in combination with platinum-based chemotherapy and bevacizumab followed by maintenance treatment with IMFINZI and bevacizumab with or without LYNPARZA in newly diagnosed patients with advanced ovarian cancer without tumor BRCA mutations. Patients were randomized 1:1:1 to: Arm 1 (control), induction therapy with platinum-based chemotherapy in combination with bevacizumab and placebo followed by maintenance treatment with bevacizumab plus placebo; Arm 2, induction therapy with platinum-based chemotherapy in combination with bevacizumab and IMFINZI followed by maintenance IMFINZI and bevacizumab plus placebo; or Arm 3, induction therapy with platinum-based chemotherapy in combination with bevacizumab and IMFINZI followed by maintenance IMFINZI and bevacizumab plus LYNPARZA. In all arms, platinum-based chemotherapy was administered every 3 weeks (q3w) for up to 6 cycles, bevacizumab was administered q3w for up to 15 months, IMFINZI or placebo was administered q3w for up to 24 months, and LYNPARZA or placebo was administered twice daily for up to 24 months. The primary endpoint of the trial is progression-free survival (PFS) as assessed by investigator for Arm 3 compared to Arm 1 (control) in the overall trial population which included patients without tumor BRCA mutations and in the subset of these patients with homologous recombination deficiency (HRD)-positive disease. Key secondary endpoints include PFS as assessed by investigator in Arm 2 compared to control, as well as comparisons for overall survival (OS). DUO-O enrolled over 1200 patients across all treatment arms at 179 study locations. For more information about the trial, visit ClinicalTrials.gov . IMFINZI IMFINZI (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses. IMFINZI is the only approved immunotherapy and the global standard of care in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiation therapy based on the PACIFIC Phase III trial. IMFINZI is also approved in the US, EU, Japan, China and many other countries around the world for the treatment of extensive-stage small cell lung cancer (SCLC) based on the CASPIAN Phase III trial. Additionally, IMFINZI is approved in combination with a short course of IMJUDO ® (tremelimumab-actl) and chemotherapy for the treatment of metastatic NSCLC in the US, EU and Japan based on the POSEIDON Phase III trial. In addition to its indications in lung cancer, IMFINZI is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer in the US, EU, Japan and several other countries; in combination with IMJUDO in unresectable hepatocellular carcinoma in the US, EU and Japan; and in previously treated patients with advanced bladder cancer in a small number of countries. Since the first approval in May 2017, more than 200,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, several gastrointestinal cancers and other solid tumors. LYNPARZA LYNPARZA ® (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumors harboring a deficiency in homologous recombination repair (HRR), such as those with mutations in BRCA1 and/or BRCA2 , or those where deficiency is induced by other agents (such as new hormonal agents [NHAs]). Inhibition of PARP with LYNPARZA leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. LYNPARZA is currently approved in a number of countries across multiple tumor types including maintenance treatment of platinum-sensitive relapsed ovarian cancer and as both monotherapy and in combination with bevacizumab for the 1st-line maintenance treatment of BRCA -mutated ( BRCA m) and homologous recombination deficiency (HRD)-positive advanced ovarian cancer, respectively; for germline BRCA -mutated (g BRCA m), HER2-negative metastatic breast cancer (in the EU and Japan this includes locally advanced breast cancer); for g BRCA m, HER2-negative high-risk early breast cancer (in Japan this includes all BRCA m HER2-negative high-risk early breast cancer); for g BRCA m metastatic pancreatic cancer; in combination with abiraterone for the treatment of metastatic castration-resistant prostate cancer (mCRPC) in whom chemotherapy is not clinically indicated (in the EU) and as monotherapy in HRR gene-mutated mCRPC in patients who have progressed on prior NHA treatment ( BRCA m only in the EU and Japan). In China, LYNPARZA is approved for the treatment of BRCA -mutated mCRPC, as a 1st-line maintenance therapy in BRCA -mutated advanced ovarian cancer as well as 1st-line maintenance treatment with bevacizumab for HRD-positive advanced ovarian cancer. LYNPARZA , which is being jointly developed and commercialized by AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada, has been used to treat over 75,000 patients worldwide.

(NASDAQ: IDYA), a precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced achievement of First-Patient-In in the Phase 1 clinical trial evaluating IDE161 (NCT 05787587) and release of a poster presentation profiling IDE161 at AACR 2023. IDE161 is a potent, selective, small-molecule inhibitor of PARG, a novel and mechanistically-differentiated target in the same clinically validated pathway as poly (ADP-ribose) polymerase (PARP). "We are excited to clinically investigate IDE161 as a potential first-in-class synthetic lethality treatment for cancer patients with homologous recombination deficiencies (HRD). We believe IDE161 may be impactful for ER+ / Her2- breast cancer patients with HRD, as well as for patients having ovarian cancer and other solid tumors with HRD, for whom current treatment options are limited," said Dr. Darrin M. Beaupre, M.D., Ph.D., Chief Medical Officer, IDEAYA Biosciences. "Based on its preclinical tolerability profile, IDE161 may also be suitable for evaluation with several distinct classes of combination agents, providing multiple paths to demonstrate patient benefit in these populations," continued Dr. Beaupre. Dr. Timothy Yap, M.D., Ph.D., Associate Professor of Investigational Cancer Therapeutics at The University of Texas MD Anderson Cancer Center in Houston, the site which dosed the first patient, is a leading principal investigator for the Phase 1 clinical trial evaluating IDE161. IDEAYA's Phase 1 clinical trial will evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic properties and preliminary efficacy of IDE161 as monotherapy in patients having tumors with homologous recombination deficiency (HRD). The clinical protocol includes dose escalation in solid tumors with HRD. Subject to selection of an expansion dose, the company is planning expansion in cohorts for patients having HRD tumors in breast cancer, ovarian cancer, and a basket of other solid tumors. The breast cancer cohort will focus on estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (Her2-) tumors with HRD, which represent approximately 10% to 14% of breast cancer patients. IDEAYA is planning to present a poster with preclinical data profiling IDE161 at the 2023 Annual Meeting of the American Association for Cancer Research (AACR) on Wednesday, April 19, 2023: Abstract 6093: "IDE161, a potential first-in-class clinical candidate PARG inhibitor, selectively targets Homologous-Recombination-Deficient and PARP inhibitor resistant breast and ovarian tumors" (Abed, M. et al.)
