Moleculin Announces Completion of Third Single Ascending Dose (SAD) Cohort in Phase 1a Clinical Trial of WP1122 in the UK

On August 19, 2022 Moleculin Biotech, Inc., (Nasdaq: MBRX) ("Moleculin" or the "Company"), a clinical stage pharmaceutical company with a broad portfolio of drug candidates targeting highly resistant tumors and viruses, reported preliminary results from the third cohort of the Company’s first-in-human Phase 1a study of WP1122 (Press release, Moleculin, AUG 19, 2022, View Source [SID1234618507]). This cohort consisted of 10 subjects dosed with 32 mg/kg or placebo in the dose escalation trial evaluating the safety and pharmacokinetics (PK) of WP1122 in healthy volunteers in the United Kingdom (UK). Based on the overall results in Cohort 3, the Safety Review Committee (SRC) for the study deemed the third single ascending dose (SAD) cohort dose safe and well-tolerated, allowing the Company to begin its fourth SAD Cohort with a dose escalation to 64 mg/kg. Additionally, dosing of WP1122 in the multiple ascending dose (MAD) cohorts will commence at a total daily dose of 32 mg/kg, which has been shown to be safe in the single dose cohort.

The Phase 1a, first-in-human, randomized, double-blind, placebo-controlled, overlapping SAD and MAD study is investigating the effects of WP1122 administered as an oral solution in healthy human volunteers. It is the first step in a potential investigation of WP1122 for the treatment of COVID-19. Furthering such an investigation is dependent upon the volatility and unpredictability of COVID-19 incidence in various countries and the ability to recruit patients for a feasible study.

Dose escalation is taking place in sequential SAD cohorts, and MAD will now begin as 3 SAD have been successfully completed. This study in healthy volunteers is exploring safety and PK, and possible subsequent antiviral clinical development is intended to be in patients infected with SARS-CoV-2 to further evaluate safety and establish a favorable risk/benefit profile. The Company expects to enroll approximately 80 subjects in this Phase 1 trial.

Walter Klemp, Chairman and Chief Executive Officer of Moleculin commented, "WP1122 has continued to demonstrate the favorable safety and tolerability profile we expected. With three SAD cohorts successfully completed, we can begin the MAD phase of the trial and are another step closer to establishing a maximum tolerated dose. Throughout the three completed cohorts, WP1122 has demonstrated no dose escalating stopping criteria, and we are pleased with the progress of WP1122 toward becoming a potential treatment of certain viral diseases and cancers."

During the SAD portion of this study, dose escalation will proceed up to a maximum dose of 64 mg/kg as a single dose. Dosing of WP1122 began in SAD at 8 mg/kg as a single dose and has escalated in two-fold increments (i.e., to 16, 32 and now to 64 mg/kg as single doses) in subsequent cohorts. The first dose administered in MAD will be 16 mg/kg every 12 hours (32 mg/kg/day) for 7 days and dosing in the second MAD cohort will escalate to 32 mg/kg every 12 hours (64 mg/kg/day) for 7 days.

For more information about the study, please visit clinicaltrials.gov and reference identifier NCT05195723. Moleculin is also in the process of identifying additional countries where potential future Phase 2 COVID-19 clinical studies could occur and is also in discussions with potential investigators interested in the possible study of WP1122 in other viruses and cancer indications.

About WP1122

WP1122 was developed as a 2-DG prodrug to provide a more favorable pharmacological profile and was found to have greater potency than 2-DG alone in preclinical models where tumor cells require higher glycolytic activity than normal cells. WP1122 has also been shown to have a greater antiviral effect than 2-DG against SARS-CoV-2 in MRC-5 cells in culture. The improved pharmacokinetic and pharmacodynamic (PK/PD) profile of WP1122 compared to 2-DG was noted in female mice following oral dosing at equimolar (i.e., equivalent levels of 2-DG) doses.

While the Company is in the process of identifying additional countries where potential future Phase 2 COVID-19 clinical studies might occur, the volatility and unpredictability of COVID-19 incidence in various countries may limit the ability to recruit certain subjects and could make it infeasible to conduct a Phase 2 clinical trial in a given country. Additionally, Moleculin recently received IND clearance from the U.S. Food and Drug Administration (FDA) to initiate a Phase 1 study of WP1122 for the treatment of Glioblastoma Multiforme (GBM). The Company is seeking collaborators with the intent to commence clinical trials of WP1122 in other viruses and cancer indications including GBM, pancreatic cancer and others.

Kyowa Kirin Receives European Commission Approval for Use of CRYSVITA®(burosumab) for the Treatment of Tumour-Induced Osteomalacia (TIO)

On August 19, 2022 Kyowa Kirin Co., Ltd. (TSE: 4151, Kyowa Kirin) reported that the European Commission (EC) approved CRYSVITA (burosumab) for the treatment of FGF23-related hypophosphataemia in Tumour-Induced Osteomalacia (TIO) associated with phosphaturic mesenchymal tumours (PMTs) that cannot be curatively resected or localised in children and adolescents aged 1 to 17 years and in adults (Press release, Kyowa Hakko Kirin, AUG 19, 2022, View Source [SID1234618506]).1 CRYSVITA is also already licensed in the EU for use in the rare disease X-Linked Hypophosphataemia (XLH), for children and adolescents between 1 and 17 years of age with radiographic evidence of bone disease, and in adults.2

Also known as oncogenic osteomalacia, TIO is an acquired disorder caused by typically small, slow-growing, benign PMTs.3,4 It is a rare condition with fewer than 1000 cases reported in the medical literature,4 which mainly affects adults and with a mean onset age of 40 – 45 years.3,5 TIO is associated with progressive and debilitating musculoskeletal deficits,6,7 ultimately having a detrimental impact on ability to perform daily activities, as well as on physical and social wellbeing.8

A cure for TIO can be achieved with complete surgical resection of the causative tumour(s), however, surgical resection is not always possible due to the anatomical location and difficulty in detecting tumours.3,5 TIO may recur and persist following incomplete or unsuccessful surgical resection.9

With this approval by the European Commission, CRYSVITA is the first biologic treatment available to EU patients within its licensed indication for TIO. CRYSVITA blocks the action of fibroblast growth factor-23 (FGF23), which is produced in excess in TIO, restoring phosphate homeostasis.2,10

"The approval by the European Commission is a very welcome milestone for those living with TIO that cannot be cured by complete surgical resection," said Professor Ralf Oheim, Department of Osteology and Biomechanics, University Medical Center Hamburg. "With the challenges faced by those living with TIO and those treating it, the unmet need in TIO has been clear for a long time and today’s decision will help support those living with TIO and those healthcare professionals supporting them address such unmet need."

"This is a momentous day for the TIO community in Europe and I’m proud that Kyowa Kirin can be a part of meeting the needs of people who have such a high unmet need", said Abdul Mullick, President of Kyowa Kirin International. "Our purpose is to make people smile, and with this new indication for a rare disease with limited available treatment options, we can truly say that together with the TIO community, we are living our purpose."

With this EC approval, Kyowa Kirin International will work with local health authorities in each country under the purview of the EC to ensure that those living with TIO are able to gain access to CRYSVITA as soon as possible.

About Tumour-Induced Osteomalacia (TIO)
TIO is characterised by chronic hypophosphataemia caused by tumour(s) secreting excess fibroblast growth factor 23 (FGF23),3 which can lead to issues such as decreased intestinal absorption of phosphate and compromised vitamin D activation.3,4

The most common signs and symptoms include bone pain, difficulty walking, pathological fractures, height loss and muscle weakness.6 In TIO, muscle weakness and pain severely interfere with physical functioning, including standing up without assistance, walking and ability to work.8 The pain in TIO also severely interferes with mood and moderately interferes with enjoyment of life for those living with it.8

TIO diagnosis is often missed and/or delayed and testing serum phosphate levels is important for diagnosis.3 The only cure in TIO is complete removal of the causative tumour(s).3 Pharmacological treatment should be considered in TIO cases where tumour(s) cannot be curatively resected or localised.3 Restoring phosphate homeostasis is essential to improve the health of people living with TIO.3

About CRYSVITA (burosumab) in TIO
CRYSVITA (burosumab) was created and developed by Kyowa Kirin and is a recombinant fully human monoclonal antibody that binds to and inhibits the activity of FGF23.2 CRYSVITA blocks the action of FGF23, which is produced in excess in TIO, restoring phosphate homeostasis.2

The efficacy and safety of CRYSVITA have been demonstrated in two Phase 2 clinical trials published in the disease area of TIO.11,12 CRYSVITA was well-tolerated and demonstrated an acceptable safety profile.11,12

Following this new EC approval, CRYSVITA is now indicated in the EU for the treatment of FGF23-related hypophosphataemia in TIO associated with PMTs that cannot be curatively resected or localised in children and adolescents aged 1 to 17 years and in adults1, as well as for XLH in children and adolescents aged 1 to 17 years with radiographic evidence of bone disease, and in adults.2 CRYSVITA is given as a subcutaneous injection, every 4 weeks in adults and every 2 weeks in children and adolescents aged 1 to 17 years.2

CRYSVITA is currently approved for use in the treatment of TIO in a number of countries, including the United States13 and Japan.14

Kyowa Kirin and Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE: Ultragenyx) have been collaborating in the development and commercialisation of CRYSVITA globally, based on the collaboration and licence agreement between Kyowa Kirin and Ultragenyx.

"There is a major unmet need in the treatment of advanced or metastatic ER+/HER2- breast cancer after resistance builds in the earlier lines of treatment," commented Elcin Barker Ergun, Chief Executive Officer of the Menarini Group. "The acceptance of our application for review by the EMA represents a significant step for our company and we look forward to working with the agency to potentially bring elacestrant to patients suffering from second- and third-line ER+/HER2- advanced or metastatic breast cancer in Europe."

The Phase 3 EMERALD study (NCT03778931) evaluated elacestrant compared to SOC endocrine monotherapy (investigators’ choice of either fulvestrant or an aromatase inhibitor) in ER+/HER2- advanced or metastatic breast cancer patients. The study results were recently published online in the Journal of Clinical Oncology (JCO) on May 18, 2022. Further post-hoc analysis from the study will be presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2022 taking place September 9-13, 2022, in Paris, France.

The Menarini Group obtained global licensing rights for elacestrant in July 2020 from Radius Health, Inc, who conducted and successfully completed the EMERALD study. Based on the positive phase 3 data, Stemline submitted a MAA to EMA on July 27, 2022. The regulatory review for elacestrant is also underway in the U.S. as the Food and Drug Administration (FDA) has recently accepted a New Drug Application for elacestrant designating a Priority Review. The Menarini Group is now fully responsible for global registration, commercialization and further development activities for elacestrant.

About Elacestrant (RAD1901) and the EMERALD Phase 3 Study
Elacestrant is an investigational selective estrogen receptor degrader (SERD). In 2018, elacestrant received Fast Track designation from the FDA. Preclinical studies completed prior to EMERALD indicate that the compound has the potential for use as a single agent or in combination with other therapies for the treatment of breast cancer. The EMERALD Phase 3 trial is a randomized, open label, active-controlled study evaluating elacestrant as second- or third-line monotherapy in ER+/HER2- advanced/metastatic breast cancer patients. The study enrolled 477 patients who had received prior treatment with one or two lines of endocrine therapy, including a CDK 4/6 inhibitor. Patients in the study were randomized to receive either elacestrant or the investigator’s choice of an approved hormonal agent. The primary endpoint of the study was progression-free survival (PFS) in the overall patient population and in patients with estrogen receptor 1 gene (ESR1) mutations. Secondary endpoints included evaluation of overall survival (OS), objective response rate (ORR), and duration of response (DOR) and safety.
