CytRx Corporation highlights the positive results from the Phase 2/3 trial of arimoclomol, an investigational treatment for Niemann-Pick disease type C. The study showed a significant treatment effect with a 65% relative reduction in disease progression over 12 months. Notably, in patients aged 4 and above, arimoclomol demonstrated an 82% reduction. The treatment was well-tolerated, with fewer serious adverse events compared to placebo. Orphazyme is awaiting a regulatory decision in Europe by Q4 2021 and is assessing the path forward in the U.S.
Positive
Significant treatment effect with a 65% reduction in disease progression over 12 months.
In patients aged ≥4 years, a treatment difference of -1.80 points indicates an 82% reduction in disease progression.
Arimoclomol was well-tolerated with fewer serious adverse events (14.7%) compared to placebo (31.3%).
Regulatory review ongoing in Europe, with a decision expected in Q4 2021.

12-Month Study of Arimoclomol Showed a Clinically Meaningful Treatment Effect, Corresponding to a Reduction in Disease Progression
Highlights Arimoclomol is Under Regulatory Review in Europe, With a Decision Expected in Q4 2021
Notes Orphazyme Stated it Continues to Evaluate a Path Forward for Arimoclomol in the U.S.
LOS ANGELES--(BUSINESS WIRE)--
CytRx Corporation (OTCQB:CYTR) (“CytRx” or the “Company”), a specialized biopharmaceutical company focused on research and development for the oncology and neurodegenerative disease categories, today highlighted that Orphazyme A/S (NASDAQ:ORPH) ("Orphazyme") published the results from a Phase 2/3 trial of arimoclomol, an investigational heat-shock protein amplifier, in Niemann-Pick disease type C (NPC) in the peer-reviewed Journal of Inherited Metabolic Disease (JIMD). The online publication is available here.
The Phase 2/3 trial (NPC-002; ClinicalTrials.gov identifier: NCT02612129), was a prospective, randomized, double-blind, placebo-controlled study. Fifty patients aged 2–18 years were randomized 2:1 to arimoclomol:placebo, stratified by miglustat use. Routine clinical care was maintained. Arimoclomol was administered orally three times daily. The primary endpoint was change in 5-domain NPC Clinical Severity Scale (NPCCSS) score from baseline to 12 months, as described by Mengel et al.1 and Patterson et al2. The 5-domain NPCCSS comprises the domains determined to be most clinically relevant to patients, caregivers, and clinicians: ambulation, cognition, fine motor skills, speech, and swallowing (Cortina-Borja et al.3). A recent validation of the 5-domain NPCCSS shows that a change of 1 point or greater on the total score constitutes a clinically meaningful change for caregivers/patients and physicians (Patterson et al4).
At 12-months, a significant treatment effect in favor of arimoclomol of −1.40 points (95% CI: −2.76, −0.03; p = 0.046) was observed, corresponding to a 65% relative reduction in annual disease progression. In the prespecified subgroup of patients receiving miglustat as routine care, arimoclomol resulted in stabilization of disease severity with a treatment difference of −2.06 in favor of arimoclomol (p = 0.006). In the pre-specified subgroup of patients ≥4 years of age the mean treatment difference was −1.80 in favor of arimoclomol (p=0.016), corresponding to 82% relative reduction in annual disease progression.
Arimoclomol was well-tolerated, with adverse events occurring in 88.2% of patients receiving arimoclomol and 75.0% of patients receiving placebo. Fewer patients had serious adverse events with arimoclomol (14.7%) versus placebo (31.3%).
Orphazyme’s Chief Medical Officer stated the following in an announcement this week:
“We are pleased to share the data from our Phase 2/3 trial in JIMD. NPC is a rare, inherited progressive neurodegenerative disorder with a high unmet medical need for disease-modifying treatment options. This trial demonstrated a statistically significant and clinically meaningful treatment effect of arimoclomol in NPC supported by significant and consistent effects across several disease- and pharmacodynamic biomarkers. We believe these data establish the potential of arimoclomol as an efficacious and well-tolerated disease-modifying treatment for NPC.”
Orphazyme’s Chief Executive Officer added the following in an announcement this week:
“We are committed to serving the NPC community and are working expeditiously to deliver this potential new medicine to patients. Arimoclomol is under regulatory review in Europe, with an anticipated CHMP opinion in Q4 2021, and we continue to evaluate the path forward in the U.S. following the recent FDA response.”
Steven A. Kriegsman, Chairman and Chief Executive Officer of CytRx, commented:
"CytRx is encouraged by Orphazyme’s published results of its Phase 2/3 trial of arimoclomol in Niemann-Pick disease type C, which exhibited a statistically significant and clinically meaningful treatment effect on reducing disease progression. The biomarker data further suggests arimoclomol can be an effective solution for young patients suffering from NPC, with relatively few serious adverse effects. We look forward to monitoring Orphazyme’s pursuit of European regulatory approval for arimoclomol in Q4 2021 and additional developments in the U.S. following the FDA’s feedback."
