TransCon CNP: The New Frontier of Growth Biology


Slide 53

TransCon CNP: The New Frontier of Growth Biology TransCon CNP may provide benefit in several growth disorders — as monotherapy, and potentially in combination with TransCon hGH C-type natriuretic peptide (CNP) is a promising therapeutic pathway for treating growth failure and dwarfism Inhibits the overactive signalling resulting from both ligand-dependent and independent signalling through the mutated FGFR3 receptor causing achondroplasia Due to its very short half-life (2-3 minutes), CNP has historically not been a druggable target, as prolonged exposure is required for improved growth Phase 1 data support the TransCon CNP Target Product Profile


Slide 54

Achondroplasia: High Morbidity The Application of Clinical Genetics, 2014:7117-125 Up to 85% of patients require intervention for obstructive sleep apnea and respiratory insufficiency 25% of children have hearing loss increasing to > 50% in adulthood 22% have osteotomy 15-30% have fixed kyphotic deformity Up to 28% require cevicomedullary decompression by age 4 10% of children have neurological signs of spinal stenosis 80% of adults have clinical signs and symptoms related to spinal stenosis


Slide 55

Achondroplasia: Higher Mortality Analysis courtesy of Trinity Partners: Trinity Partners Medicare Analysis. Results are preliminary and achondroplasia vs overall Medicare patients have not been risk adjusted. Preliminary analysis shows among achondroplasia patients a median age of death of 60 years – consistent with the published literature Markedly higher rates of death in these patients compared to the overall Medicare population, especially among patients <70 years

Achondroplasia Signaling Defect is Well Understood1 1Adapted from Current Opin Pediatrics 2010; 22:516-523 TransCon CNP continuously inhibits abnormal FGFR3 signaling, restoring proliferation and differentiation of chondrocytes to rebalance bone growth CNP does not alter the function of FGF receptors or change endogenous levels of FGF ligands, reducing the risk of interfering with normal FGF biology


Slide 58

TransCon CNP Design TransCon technology is designed to provide effective shielding of CNP: From neutral endopeptidase degradation in subcutaneous tissue and blood compartment Minimize binding of TransCon CNP to the NPR-C receptor Reduce binding of TransCon CNP to the NPR-B receptor in vasculature to avoid hypotension CNP liberated from TransCon CNP maintains small enough size to allow penetration into growth plates TransCon carrier TransCon linker CNP (inactive) Active CNP Receptor Linker cleavage dependent upon pH and temperature Renal clearance

Ascendis Pharma A/S Provides Pipeline Update and Reviews Progress Towards Vision 3x3 at 38th

Annual J.P. Morgan Healthcare Conference

COPENHAGEN, Denmark, January 12, 2020 (GLOBE NEWSWIRE) – Ascendis Pharma A/S (Nasdaq: ASND), a biopharmaceutical company that utilizes its innovative TransCon technologies to address significant unmet medical needs, will provide an outlook for 2020 and review progress towards Vision 3x3, the company’s strategic roadmap through 2025 to achieve sustainable growth at the 38th Annual J.P. Morgan Healthcare Conference in San Francisco.

“2019 was a transformative year for Ascendis Pharma. For our endocrinology rare disease portfolio, we were successful in our first phase 3 trial for a TransCon product candidate, TransCon hGH, and we advanced two other programs globally into phase 2. In addition, we established oncology as our second therapeutic area with a highly-differentiated pipeline leveraging the TransCon technology,” said Jan Mikkelsen, Ascendis Pharma’s President and Chief Executive Officer. “As groundbreaking as 2019 was for Ascendis, it was only the beginning of our path to build a leading fully-integrated global biopharma company. We are on track with our Vision 3x3 goals to deliver multiple sources of sustainable growth as we seek to make a meaningful difference in patients’ lives.”

Pipeline Updates and 2020 Outlook

 

   

TransCon hGH: TransCon hGH is an investigational long-acting prodrug of human growth hormone (hGH) in phase 3 development as a once-weekly treatment for growth hormone deficiency (GHD). TransCon hGH releases unmodified somatropin and has demonstrated a statistically significant increase in height velocity compared to a daily hGH in the phase 3 heiGHt Trial:

 

   

Ascendis Pharma recently held two pre-BLA meetings with the U.S. Food and Drug Adminstration (FDA) to review its Chemistry, Manufacturing and Controls (CMC), and clinical/non-clinical packages for TransCon hGH as a potential treatment for pediatric GHD. The company is on track to file a Biologics License Application with the FDA in the second quarter. A Marketing Authorisation Application to the European Medicines Agency is planned to follow in the fourth quarter.

 

   

Long-term data presented from the ongoing enliGHten Trial (long-term extension) continued to demonstrate statistically superior growth of subjects treated with once-weekly TransCon hGH in the heiGHt Trial who continued into enliGHten, compared to those who started treatment with daily Genotropin® and switched to TransCon hGH after one year. The adverse event profile of TransCon hGH, which was comparable to Genotropin in the phase 3 heiGHt Trial, was consistent across the phase 3 clinical trials.

 

   

The company plans to submit regulatory filings to initiate a global, phase 3 clinical trial in adult GHD during the first quarter, and to initiate a trial in pediatric GHD in Japan during the fourth quarter.

 

   

TransCon PTH: TransCon PTH is an investigational long-acting prodrug of parathyroid hormone (PTH) in development as a once-daily replacement therapy for hypoparathyroidism (HP) designed to replace


 

PTH at physiologic levels for 24 hours each day and fully address all aspects of the disease:

 

   

Following completion of screening of subjects in the recently expanded phase 2 PaTH Forward Trial, Ascendis intends to enroll approximately 55 subjects in the trial. The company expects to report top-line results from the trial around the end of March 2020, with six-month data from the open-label extension phase expected in the third quarter.

 

   

Preliminary data presented from the first eight subjects who completed four weeks of follow-up in the open-label extension portion of the phase 2 PaTH Forward Trial reinforce the company’s target product profile for TransCon PTH as a promising new potential therapy for HP in the absence of standard of care.

 

   

The company plans to submit regulatory filings to initiate a global, phase 3 clinical trial in adults with HP during the fourth quarter.

 

   

TransCon CNP: TransCon CNP is an investigational long-acting prodrug of CNP in development as a therapy for children with achondroplasia, the most common form of dwarfism, for which there is no FDA-approved treatment. TransCon CNP is designed to provide continuous exposure of CNP at safe, therapeutic levels via a single, weekly subcutaneous dose:

 

   

Ascendis is conducting the phase 2 ACcomplisH Trial of TransCon CNP in children (ages 2-10 years) with achondroplasia and plans to escalate sequential dose cohorts throughout 2020.

 

   

The company is expanding the TransCon CNP program in China through its strategic investment in VISEN Pharmaceuticals, with initiation of a second phase 2 trial in children with achondroplasia during the fourth quarter.

 

   

Oncology: Ascendis continues to advance a pipeline of multiple pre-clinical programs in oncology by applying both systemic and sustained localized TransCon technologies for clinically validated pathways:

 

   

Additional data from non-human primate studies demonstrated that a single dose of TransCon IL-2 ß/g provided biased receptor binding and prolonged enhancement of lymphocyte counts, suggesting feasibility of every three week dosing and reduced risk of toxicity.

 

   

Ascendis Pharma’s innovative TransCon technology for sustained localized release intratumorally (IT) was accepted to participate in the FDA’s Emerging Technology Program. The program provides for enhanced interactions and dialogue with the FDA to discuss, identify and resolve potential technical and CMC regulatory questions related to the TransCon sustained IT programs prior to filing regulatory submissions.

 

   

The company plans to file an IND or equivalent for its first oncology program in 2020, furthering the goal to create best-in-class oncology therapeutics.
