DUBLIN, May 5, 2023 /PRNewswire/ -- The "Chronic Kidney Disease - Competitive landscape, 2023" report has been added to ResearchAndMarkets.com's offering. This report provides comprehensive insights about 75+ companies and 95+ drugs in Chronic Kidney Disease Competitive landscape. It covers the therapeutics assessment by product type, stage, route of administration, and molecule type. It further highlights the inactive pipeline products in this space. In March 2023, POXEL SA, announced the publication of preclinical results in autosomal dominant polycystic kidney disease (ADPKD) for PXL770, a novel, first-in-class direct adenosine monophosphate-activated protein kinase (AMPK) activator. For the first time, POXEL SA showed beneficial effects of a direct and selective AMPK activator in preclinical ADPKD models from three species mouse, human, and dog. These results confirm the potential utility of AMPK activation for this disease and support the development of PXL770 in a Phase 2 clinical program for ADPKD. In February 2023, AstraZeneca announced the successful completion of the acquisition of CinCor Pharma, Inc. The acquisition bolsters AstraZeneca's cardiorenal pipeline by adding baxdrostat (CIN-107), an aldosterone synthase inhibitor (ASI) for blood pressure lowering in treatment-resistant hypertension, to its cardiorenal portfolio. In January 2023, The U.S. Food and Drug Administration (FDA) has accepted a supplemental New Drug Application (sNDA) for Jardiance (empagliflozin) tablets, which is being investigated as a potential treatment to reduce the risk of kidney disease progression and cardiovascular death in adults with chronic kidney disease (CKD), Boehringer Ingelheim and Eli Lilly and Company announced. In November 2022, The Medical Research Council Population Health Research Unit (MRC PHRU) at the University of Oxford, which designed, conducted and analyzed EMPA-KIDNEY in a scientific collaboration with Boehringer Ingelheim and Eli Lilly and Company, announced that EMPA-KIDNEY phase III clinical trial met its primary endpoint by demonstrating a significant kidney and cardiovascular benefit for adults living with chronic kidney disease (CKD). When treated with Jardiance (empagliflozin), the risk of kidney disease progression or cardiovascular death was significantly reduced by 28% vs. placebo (HR; 0.72; 95% CI 0.64 to 0.82; P< 0.0001). In October 2022, Revelation Biosciences Inc. announced positive results in a preclinical model of acute kidney injury (AKI), chronic kidney disease (CKD). Treatment with REVTx-300 significantly reduced renal cortical fibrosis in a dose dependent manner in the medium and high dose groups (21.7% reduction (p < 0.05) and 29.3% (p < 0.05), respectively) and was comparable to a known TGF inhibitor of fibrosis used as a positive control (38.1% reduction (P < 0.05)). In October 2022, French Biopharma Company, Poxel SA announced the U.S. Food and Drug Administration (FDA) has granted orphan drug designation (ODD) to PXL770 for the treatment of patients with autosomal-dominant polycystic kidney disease (ADPKD).

NEW YORK, NY, USA I February 16, 2023 I Pfizer (NYSE: PFE) announced today positive results from the Phase 3 TALAPRO-2 study of TALZENNA ® (talazoparib), an oral poly ADP-ribose polymerase (PARP) inhibitor, in combination with XTANDI ® (enzalutamide), demonstrating a statistically significant and clinically meaningful improvement in radiographic progression-free survival (rPFS) compared to placebo plus XTANDI in men with metastatic castration-resistant prostate cancer (mCRPC), with or without homologous recombination repair (HRR) gene mutations. In addition, the U.S. Food and Drug Administration (FDA) has granted Priority Review for Pfizer’s supplemental new drug application (sNDA) for TALZENNA in combination with XTANDI for the treatment of men with mCRPC. The FDA grants Priority Review to medicines that may offer significant advances in treatment or may provide a treatment where no adequate therapy exists. The FDA’s decision on the sNDA is expected in 2023. The TALAPRO-2 results will be presented today, Thursday, February 16, at 8:00 a.m. PST during the 2023 American Society of Clinical Oncology Genitourinary Cancers Symposium (ASCO GU) as a late-breaking presentation (Abstract LBA17) and will be featured in the ASCO GU official press program. In the final rPFS analysis, TALZENNA plus XTANDI reduced the risk of disease progression or death by 37% versus placebo plus XTANDI (Hazard Ratio [HR]: 0.63; 95% Confidence Interval [CI], 0.51–0.78; P< 0.001). The median rPFS for the treatment arm was not reached at the time of analysis versus 21.9 months for placebo plus XTANDI. Median rPFS is reached when 50% of trial participants have had an event of disease progression or death. “Novel hormone therapies dramatically changed outcomes for patients with mCRPC in the last decade, and the results from the TALAPRO-2 study show that the addition of talazoparib to the existing standard of care adds significant clinical benefit,” said Neeraj Agarwal, M.D., FASCO, Professor of Oncology and Presidential Endowed Chair of Cancer Research at Huntsman Cancer Institute, University of Utah, and lead investigator for TALAPRO-2. “In addition to delaying disease progression, this combination delayed prostate-specific antigen progression and time to chemotherapy without adversely impacting patient quality of life. The TALAPRO-2 results support the potential for this combination to be practice-changing, with strong, highly consistent efficacy and observations in mCRPC patients both with or without HRR gene mutations, and across clinically relevant sub-populations.” A trend in overall survival (OS) favoring TALZENNA plus XTANDI was also observed, though these data are immature. The final OS will be reported once the predefined number of survival events has been reached. TALAPRO-2 is the first Phase 3 study to combine TALZENNA with XTANDI in patients unselected for genetic alterations in DNA damage repair pathways, directly or indirectly involved with HRR. The study also showed clinically meaningful improvement in median rPFS for patients in the study treated with TALZENNA plus XTANDI across several prospectively assessed subgroups including HRR-deficient (HR, 0.46; 95% CI, 0.30–0.70; P<0.001) and HRR-non-deficient or unknown (HR, 0.70; 95% CI, 0.54–0.89; P=0.004). Objective response rates, prostate-specific antigen (PSA) response ≥50%, and time to PSA progression and use of subsequent cytotoxic chemotherapy and antineoplastic therapy were also significantly improved in patients treated with TALZENNA plus XTANDI versus placebo plus XTANDI. Median time to definitive clinically meaningful deterioration in global health status/quality of life was also longer in those treated with TALZENNA plus XTANDI (30.8 vs 25.0 months, respectively; HR, 0.78; 95% CI, 0.62–0.99; P=0.04). “Patients with mCRPC need new treatment approaches that can improve outcomes, and the rPFS results from TALAPRO-2, which appears to be the longest observed in a randomized trial in this setting, demonstrate the potential of the TALZENNA and XTANDI combination, if approved, to become a new standard of care,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology and Rare Disease, Pfizer Global Product Development. “We are pleased that the FDA has granted Priority Review for our application, and we look forward to working with the Agency and global regulatory authorities to bring this treatment to men with mCRPC.” In the TALAPRO-2 trial, the safety of TALZENNA plus XTANDI was generally consistent with the known safety profile of each medicine. Among patients treated with TALZENNA plus XTANDI, the most common adverse events (AE) (greater than 20% of participants, all grades) included anemia (65.8%), decreased neutrophil count (35.7%), fatigue (33.7), decreased platelet count (24.6%), back pain and decreased white blood cell count (22.1% each), and decreased appetite (21.6%). The most common grade ≥3 treatment emergent adverse events (TEAEs) were anemia (46.5%), low neutrophil (18.3%), and low platelet counts (7.3%). Among patients treated with placebo plus XTANDI, the most common AEs (greater than 15%) were fatigue (29.4%), arthralgia (19.7%), back pain (18.0%), anemia (17.5%), constipation (17.0%), and decreased appetite (15.7%). The most common grade >3 AEs were hypertension (7.5%), anemia (4.2%), and fatigue (2.0%). TEAEs led to discontinuation of TALZENNA in 19.1% of patients versus 12.2% of placebo. Discontinuation rates of XTANDI were generally consistent across both study arms (10.8% vs 11.0%). Pfizer plans to submit detailed results from the trial for peer-reviewed publication. In addition to the FDA, Pfizer has also shared these data with the European Medicines Agency and other regulatory agencies to support regulatory filings and will provide further updates at the appropriate time. Neither TALZENNA nor the combination of TALZENNA plus XTANDI has been approved by any regulatory agency for the treatment of mCRPC. In addition to the TALAPRO-2 trial, the combination of TALZENNA plus XTANDI is being investigated in the TALAPRO-3 trial ( NCT04821622 ), a global, randomized, double-blind, placebo-controlled Phase 3 study in men with HRR-deficient metastatic castration-sensitive prostate cancer (mCSPC). About Metastatic Castration-Resistant Prostate Cancer Metastatic castration-resistant prostate cancer (mCRPC) is a cancer that has spread beyond the prostate gland and has progressed despite medical or surgical treatment to lower testosterone. Approximately 10%–20% of prostate cancer patients develop mCRPC within 5−7 years of diagnosis, 1 and in the U.S., in 2020, approximately 60-90 thousand cases of the 3 million prostate cancer cases were mCRPC. 2 About TALAPRO-2 The Phase 3 TALAPRO-2 trial is a two-part, two-cohort, multicenter, randomized, double-blind, placebo-controlled study that enrolled 1,106 patients with mCRPC (with no systemic treatments initiated after documentation of mCRPC) at sites in the U.S., Canada, Europe, South America, and the Asia-Pacific region. The study included two patient cohorts: all-comers (n=750) and those with HRR mutations (HRRm; n=380). Patients on androgen deprivation therapy (ADT) or who had bilateral orchiectomy in the trial were randomized to receive TALZENNA 0.5 mg/day plus XTANDI 160mg/day, or placebo plus XTANDI 160 mg/day. The primary endpoint of the trial is radiographic progression-free survival (rPFS), defined as the time from the date of randomization to first objective evidence of radiographic progression by blinded independent review, or death, whichever occurs first, in both cohort 1 (all-comers) and cohort 2 (those with HRRm). The trial is still ongoing for cohort 2. Secondary endpoints include overall survival, objective response rate, duration of response, and PSA response. For more information on the TALAPRO-2 trial ( NCT03395197 ), go to www.clinicaltrials.gov . About TALZENNA ® (talazoparib) TALZENNA (talazoparib) is an oral poly ADP-ribose polymerase (PARP) inhibitor, which plays a role in DNA damage repair. Preclinical studies have demonstrated that TALZENNA blocks PARP enzyme activity and traps PARP at the site of DNA damage, leading to decreased cancer cell growth and cancer cell death. TALZENNA is approved in over 70 countries, including the U.S., as a once daily monotherapy for the treatment of adult patients with deleterious or suspected deleterious germline breast cancer susceptibility gene (BRCA)-mutated (gBRCAm) human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer. TALZENNA is being investigated as a combination therapy with XTANDI ® (enzalutamide) in men with advanced prostate cancer, including metastatic castration-resistant prostate cancer (mCRPC) in the Phase 3 TALAPRO-2 clinical trial and metastatic castration-sensitive prostate cancer (mCSPC) in the Phase 3 TALAPRO-3 clinical trial. Preclinical studies have shown that the combination of a PARP inhibitor and an androgen receptor signaling inhibitor (ARSi) may result in an enhanced anti-tumor effect. Other combinations of TALZENNA with targeted therapies are also being studied in various solid tumors. TALZENNA ® (talazoparib) Indication in the U.S. TALZENNA (talazoparib) is indicated for the treatment of adult patients with deleterious or suspected deleterious germline breast cancer susceptibility gene (BRCA)-mutated (gBRCAm) human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer. Select patients for therapy based on an FDA-approved companion diagnostic for TALZENNA. About XTANDI ® (enzalutamide) XTANDI (enzalutamide) is an androgen receptor inhibitor indicated in the U.S. for the treatment of patients with castration-resistant prostate cancer (CRPC) and metastatic castration-sensitive prostate cancer (mCSPC). Overall survival benefit has been observed in patients treated with XTANDI in mCRPC, nmCRPC, and mCSPC . Please see Full Prescribing Information for additional safety information.

Select patients for therapy based on an FDA-approved companion diagnostic for TALZENNA. TALZENNA® (talazoparib) Important Safety Information Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) have been reported in patients who received TALZENNA. Overall, MDS/AML has been reported in <1% (3 out of 787, 0.4%) of solid tumor patients treated with TALZENNA in clinical studies. The duration of TALZENNA treatment in these three patients prior to developing MDS/AML was 4 months, 24 months, and 60 months respectively. These patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Myelosuppression consisting of anemia, leukopenia/neutropenia, and/or thrombocytopenia have been reported in patients treated with TALZENNA. Grade ≥3 anemia, neutropenia, and thrombocytopenia were reported, respectively, in 39%, 21%, and 15% of patients receiving TALZENNA. Discontinuation due to anemia, neutropenia, and thrombocytopenia occurred, respectively, in 0.7%, 0.3%, and 0.3% of patients. Monitor complete blood counts for cytopenia at baseline and monthly thereafter. Do not start TALZENNA until patients have adequately recovered from hematological toxicity caused by previous therapy. If hematological toxicity occurs, dose modifications (dosing interruption with or without dose reduction) are recommended. With respect to MDS/AML, for prolonged hematological toxicities, interrupt TALZENNA and monitor blood counts weekly until recovery. If the levels have not recovered after 4 weeks, refer the patient to a hematologist for further investigations. If MDS/AML is confirmed, discontinue TALZENNA. TALZENNA can cause fetal harm when administered to pregnant women. Advise women of reproductive potential to use effective contraception during treatment and for at least 7 months following the last dose. A pregnancy test is recommended for females of reproductive potential prior to initiating TALZENNA treatment. Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment with TALZENNA and for at least 4 months after receiving the last dose. Based on animal studies, TALZENNA may impair fertility in males of reproductive potential. Advise women not to breastfeed while taking TALZENNA and for at least 1 month after receiving the last dose because of the potential for serious adverse reactions in nursing infants. The most common adverse reactions (≥20%) of any grade for TALZENNA vs chemotherapy were fatigue (62% vs 50%), anemia (53% vs 18%), nausea (49% vs 47%), neutropenia (35% vs 43%), headache (33% vs 22%), thrombocytopenia (27% vs 7%), vomiting (25% vs 23%), alopecia (25% vs 28%), diarrhea (22% vs 26%), and decreased appetite (21% vs 22%). The most frequently reported Grade ≥3 adverse reactions (≥10%) for TALZENNA vs chemotherapy were anemia (39% vs 5%), neutropenia (21% vs 35%), and thrombocytopenia (15% vs 2%). The most common lab abnormalities (≥25%) for TALZENNA vs chemotherapy were decreases in hemoglobin (90% vs 77%), leukocytes (84% vs 73%), lymphocytes (76% vs 53%), neutrophils (68% vs 70%), platelets (55% vs 29%), and calcium (28% vs 16%) and increases in glucose (54% vs 51%), aspartate aminotransferase (37% vs 48%), alkaline phosphatase (36% vs 34%), and alanine aminotransferase (33% vs 37%). Coadministration with P-gp inhibitors or BCRP inhibitors may increase TALZENNA exposure. If coadministering with the P-gp inhibitors amiodarone, carvedilol, clarithromycin, itraconazole, or verapamil is unavoidable, reduce the TALZENNA dose to 0.75 mg once daily. When the P-gp inhibitor is discontinued, increase the TALZENNA dose (after 3–5 half-lives of the P-gp inhibitor) to the dose used prior to the initiation of the P-gp inhibitor. When coadministering TALZENNA with other known P-gp inhibitors or BCRP inhibitors, monitor patients for potential increased adverse reactions. For patients with moderate renal impairment, the recommended dose of TALZENNA is 0.75 mg once daily. For patients with severe renal impairment, the recommended dose of TALZENNA is 0.5 mg once daily. No dose adjustment is required for patients with mild renal impairment. TALZENNA has not been studied in patients requiring hemodialysis. Please see full U.S. Prescribing Information and Patient Information for TALZENNA® (talazoparib) at . About XTANDI® (enzalutamide) and Important Safety Information XTANDI (enzalutamide) is an androgen receptor inhibitor indicated in the U.S. for the treatment of patients with castration-resistant prostate cancer (CRPC) and metastatic castration-sensitive prostate cancer (mCSPC). Overall survival benefit has been observed in patients treated with XTANDI in mCRPC, nmCRPC, and mCSPC. Warnings and Precautions Seizure occurred in 0.5% of patients receiving XTANDI in seven randomized clinical trials. In a study of patients with predisposing factors for seizure, 2.2% of XTANDI-treated patients experienced a seizure. It is unknown whether anti-epileptic medications will prevent seizures with XTANDI. Patients in the study had one or more of the following predisposing factors: use of medications that may lower the seizure threshold, history of traumatic brain or head injury, history of cerebrovascular accident or transient ischemic attack, and Alzheimer’s disease, meningioma, or leptomeningeal disease from prostate cancer, unexplained loss of consciousness within the last 12 months, history of seizure, presence of a space occupying lesion of the brain, history of arteriovenous malformation, or history of brain infection. Advise patients of the risk of developing a seizure while taking XTANDI and of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. Permanently discontinue XTANDI in patients who develop a seizure during treatment. Posterior Reversible Encephalopathy Syndrome (PRES) There have been reports of PRES in patients receiving XTANDI. PRES is a neurological disorder that can present with rapidly evolving symptoms including seizure, headache, lethargy, confusion, blindness, and other visual and neurological disturbances, with or without associated hypertension. A diagnosis of PRES requires confirmation by brain imaging, preferably MRI. Discontinue XTANDI in patients who develop PRES. Hypersensitivity reactions, including edema of the face (0.5%), tongue (0.1%), or lip (0.1%) have been observed with XTANDI in seven randomized clinical trials. Pharyngeal edema has been reported in post-marketing cases. Advise patients who experience any symptoms of hypersensitivity to temporarily discontinue XTANDI and promptly seek medical care. Permanently discontinue XTANDI for serious hypersensitivity reactions. Ischemic Heart Disease In the combined data of four randomized, placebo-controlled clinical studies, ischemic heart disease occurred more commonly in patients on the XTANDI arm compared to patients on the placebo arm (2.9% vs 1.3%). Grade 3-4 ischemic events occurred in 1.4% of patients on XTANDI versus 0.7% on placebo. Ischemic events led to death in 0.4% of patients on XTANDI compared to 0.1% on placebo. Monitor for signs and symptoms of ischemic heart disease. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue XTANDI for Grade 3-4 ischemic heart disease. Falls and Fractures occurred in patients receiving XTANDI. Evaluate patients for fracture and fall risk. Monitor and manage patients at risk for fractures according to established treatment guidelines and consider use of bone-targeted agents. In the combined data of four randomized, placebo-controlled clinical studies, falls occurred in 11% of patients treated with XTANDI compared to 4% of patients treated with placebo. Fractures occurred in 10% of patients treated with XTANDI and in 4% of patients treated with placebo. Embryo-Fetal Toxicity The safety and efficacy of XTANDI have not been established in females. XTANDI can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment with XTANDI and for 3 months after the last dose of XTANDI. Adverse Reactions (ARs) In the data from the four randomized placebo-controlled trials, the most common ARs (≥ 10%) that occurred more frequently (≥ 2% over placebo) in XTANDI-treated patients were asthenia/fatigue, back pain, hot flush, constipation, arthralgia, decreased appetite, diarrhea, and hypertension. In the bicalutamide-controlled study, the most common ARs (≥ 10%) reported in XTANDI-treated patients were asthenia/fatigue, back pain, musculoskeletal pain, hot flush, hypertension, nausea, constipation, diarrhea, upper respiratory tract infection, and weight loss. In AFFIRM, the placebo-controlled study of metastatic CRPC (mCRPC) patients who previously received docetaxel, Grade 3 and higher ARs were reported among 47% of XTANDI-treated patients. Discontinuations due to adverse events (AEs) were reported for 16% of XTANDI-treated patients. In PREVAIL, the placebo-controlled study of chemotherapy-naive mCRPC patients, Grade 3-4 ARs were reported in 44% of XTANDI patients and 37% of placebo patients. Discontinuations due to AEs were reported for 6% of XTANDI-treated patients. In TERRAIN, the bicalutamide-controlled study of chemotherapy-naive mCRPC patients, Grade 3-4 ARs were reported in 39% of XTANDI patients and 38% of bicalutamide patients. Discontinuations with an AE as the primary reason were reported for 8% of XTANDI patients and 6% of bicalutamide patients. In PROSPER, the placebo-controlled study of non-metastatic CRPC (nmCRPC) patients, Grade 3 or higher ARs were reported in 31% of XTANDI patients and 23% of placebo patients. Discontinuations with an AE as the primary reason were reported for 9% of XTANDI patients and 6% of placebo patients. In ARCHES, the placebo-controlled study of metastatic CSPC (mCSPC) patients, Grade 3 or higher AEs were reported in 24% of XTANDI-treated patients. Permanent discontinuation due to AEs as the primary reason was reported in 5% of XTANDI patients and 4% of placebo patients. Lab Abnormalities: Lab abnormalities that occurred in ≥ 5% of patients, and more frequently (> 2%) in the XTANDI arm compared to placebo in the pooled, randomized, placebo-controlled studies are neutrophil count decreased, white blood cell decreased, hyperglycemia, hypermagnesemia, hyponatremia, and hypercalcemia. Hypertension: In the combined data from four randomized placebo-controlled clinical trials, hypertension was reported in 12% of XTANDI patients and 5% of placebo patients. Hypertension led to study discontinuation in < 1% of patients in each arm. Drug Interactions Effect of Other Drugs on XTANDI Avoid strong CYP2C8 inhibitors, as they can increase the plasma exposure to XTANDI. If co-administration is necessary, reduce the dose of XTANDI. Avoid strong CYP3A4 inducers as they can decrease the plasma exposure to XTANDI. If co-administration is necessary, increase the dose of XTANDI. Effect of XTANDI on Other Drugs Avoid CYP3A4, CYP2C9, and CYP2C19 substrates with a narrow therapeutic index, as XTANDI may decrease the plasma exposures of these drugs. If XTANDI is co-administered with warfarin (CYP2C9 substrate), conduct additional INR monitoring. Please see Full Prescribing Information for additional safety information.
