Impact of Condoliase on Health-related Quality of Life in Participants With Radicular Leg Pain Associated With Lumbar Disk Herniation

Article

作者: Gupta, Pragya B. ; Kim, Kee D. ; Patel, Anand ; Chauhan, Kinsuk ; Candido, Kenneth ; Watanabe, Jun ; Macadaeg, Kevin E. ; Rivera, Jose ; Zucker, Evan ; Seo, Takayuki

Study Design.:

An exploratory analysis of a randomized, double-blind, sham-controlled, phase three study.

Objective.:

To evaluate the impact of SI-6603 (condoliase) on health-related quality of life (HRQoL)-related outcomes in patients with lumbar disk herniation (LDH)-associated radicular leg pain from the Discovery 6603 study (NCT03607838).

Summary of Background Data.:

Condoliase is a novel chemonucleolytic agent that selectively degrades chondroitin sulfate in the nucleus pulposus. Condoliase is approved in Japan for the treatment of radicular leg pain associated with LDH. Recently, the Discovery 6603 study demonstrated the efficacy and tolerability of condoliase in the United States (US).

Methods.:

Adults with LDH and unilateral radicular leg pain were randomized to receive a single intradiscal injection of condoliase (1.25 units) or sham, followed by 52 weeks of observation. Exploratory HRQoL-related outcomes included change from baseline (CFB) in EuroQol Group 5-Dimension Quality of Life instrument, 5-Level version (EQ-5D-5L), and visual analogue scale (EQ-VAS), CFB in the 36-item Short Form Health Survey (SF-36), Patient Global Impression of Change (PGIC), Clinical Global Impression of Change (CGIC), and CFB in Work Productivity and Activity Impairment (WPAI) scores. EQ-5D-5L and SF-36 measures were assessed using a longitudinal analysis model.

Results.:

Of 352 randomized participants, 341 constituted the modified intention-to-treat population (condoliase: 169; sham: 172). Condoliase showed numerically greater improvements in EQ-5D-5L self-care and pain/discomfort dimensions at week 13 and week 52 compared with sham (P<0.05). The SF-36 physical component and WPAI scores numerically favored condoliase compared with sham. Patients and clinicians more frequently reported “very much improved” in overall status following condoliase treatment versus sham.

Conclusions.:

Previous findings confirmed the efficacy and tolerability of condoliase for LDH management. Condoliase showed notable improvements in exploratory HRQoL-related outcomes, which were consistent across multiple patient-reported measures. Condoliase has the potential to enhance QoL and work productivity in individuals with LDH.

Percutaneous enzymatic chemonucleolysis of intervertebral disks appears safe and effective in treatment of acute-onset paraparesis and paraplegia in small dogs

Article

作者: Freeman, Paul ; Jeffery, Nick D. ; Donoghue, Eileen M. ; Atiee, Genna

Abstract:

Objective:

To investigate the safety and effectiveness of intradiscal chondroitinase injection as a pragmatic treatment for nonambulatory paraparesis and paraplegia in small dogs.

Methods:

In this phase 1 clinical trial, dogs presented to 2 university neurology clinics between January 2023 and June 2024 with acute-onset nonambulatory paraparesis or paraplegia occurring within 48 hours before presentation. Included animals weighed < 15 kg and were between 2 and 10 years old, with caregivers who were unable to afford decompressive surgery. Under fluoroscopic guidance, each dog received 1.25 U of chondroitinase ABC into each of 4 consecutive intervertebral disks in the clinically identified lesion location. Recovery was defined as the ability to walk 50 steps without assistance by 4 months after the injection.

Results:

54 dogs were included, with 4 lost to sufficient follow-up. In those with appropriate follow-up, 38 of 40 dogs (proportion, 0.95; 95% CI, 0.83 to 1.00) with intact pain sensation to the hindquarters recovered by a median of 11 days after the intervention, and 4 of 10 dogs (0.4; 95% CI, 0.17 to 0.69) without pain sensation recovered. No adverse effects related to the injection procedure were detected.

Conclusions:

In dogs with intact pain perception, this nonsurgical intervention is associated with similar proportion and time to recover as decompressive surgery. Because of the small case number, uncertainty remains regarding the effectiveness of this intervention in dogs in which hindquarter pain perception has been lost.

Clinical Relevance:

Nonsurgical treatment for presumed disc-associated paresis and paraplegia appears promising. Randomized controlled trials are required for assessment of effectiveness versus decompressive surgery.

Perineuronal net degradation causes a delayed change in resting and sound evoked responses in the mouse auditory cortex

Article

作者: Razak, K A ; Hussain, A

Perineuronal nets (PNNs) are extracellular matrix assemblies that preferentially cover parvalbumin-expressing (PV+) interneurons in the neocortex. PV+ cells and PNNs are impaired in a variety of neurodevelopmental disorders including Fragile X Syndrome and schizophrenia. In both of these disorders, electroencephalograph (EEG) recordings show similar phenotypes, including elevated resting gamma band power and reduced temporal fidelity in the 40 Hz auditory steady state response (ASSR). Whether there is a causal link between PNN integrity and EEG abnormalities remains unclear. We tested this link by recording EEG responses in the auditory cortex (AC) in wildtype mice in which PNNs were enzymatically degraded (Chondroitinase ABC or ChABC). EEGs were recorded at two different time points (4- or 14-days post injection, cross-sectional design). In comparison to saline control, ChABC injected mice showed a ∼50 % reduction in PNN density after 4-days. However, there was no difference in resting EEG power spectral density, auditory event-related potential amplitudes or ASSR temporal fidelity between saline and ChABC mice. At the 14-day time point, there was a recovery of PNN density in the AC. Interestingly, EEG responses were abnormal at this time point, with elevated gamma band activity and reduced ASSR temporal fidelity. Thus, the electrophysiological consequences of PNN loss are not seen acutely, but over a delayed time course, suggesting abnormal plasticity after a circuit perturbation. Taken together, these data indicate acute shaping of auditory cortical responses is less dependent on PNNs, but long-term stability of responses following a circuit perturbation depends on the integrity of PNNs.

FDA adcomm votes to support Seikagaku's herniated disc injection

Despite some safety concerns, an FDA advisory committee on Friday voted 8 to 4 in favor of Japan-based Seikagaku’s condoliase injection for the treatment of radicular leg pain associated with lumbar disc herniation in adults. Much of the discussion centered on one of Seikagaku’s three clinical trials presented before the committee that failed on its primary endpoint and several secondary endpoints. Overall, the members of the FDA’s Anesthetic and Analgesic Drug Products Advisory Committee said the negative study should be weighed appropriately by the agency, and they raised short and long-term safety questions about the injection. Committee chair Brian Bateman of Stanford University School of Medicine, who voted against the injection, cautioned that the population in the negative, US-based study “might reflect the population that would ultimately use it.” He also noted several safety concerns, including that the drug has to be used in a setting that can treat anaphylaxis, and that those receiving the drug can be at risk of severe cutaneous adverse reactions (SCARs). Committee panelist Steven Schiff, professor of neurosurgery at Yale University, who voted in favor of condoliase, also raised concerns about larger numbers of people accessing it. “I could envision in the next years, a million people might get this therapy,” Schiff said, and if the prevalence of SCARs is about one in 1,000, as Seikagaku estimates, a few hundred cases of these life-threatening reactions in the US “might cause the FDA to think twice” about the approval. Michael Sprintz of Ethos Behavioral Health Group in Houston voted in favor of the injection but said he hopes the label will be appropriately narrow and ensure that those who receive it fail on the more commonly used therapies. Lumbar disc herniation can cause lower back or leg pain, but is typically resolved with existing medicines. About 20% to 50% of those in pain progress to surgery, Seikagaku said Friday. The company has presented condoliase as a less invasive alternative to surgery. About 29,000 patients have been treated with condoliase, first approved in Japan in 2018, the company said. Two of the studies were based in the US, but only one of those was positive. One key way that the two trials differed was that in the positive trial, the company used MRIs to find evidence of nerve impingement before administering the drug. But some of the panelists questioned if the MRI scans were the primary reason for the differences between the failed and positive studies. Schiff noted that the two US-based studies had very different populations and indications. And while he’s not surprised by the one failed study, he did ask: “How do you translate the success of the second study given the very rigorous inclusion and exclusion criteria? How does that get translated into approval?” DJ Kennedy of the Vanderbilt University Medical Center, who voted in favor of the drug, also said that the application of condoliase in the real world will likely be more similar to what occurred in the negative study, “unless there’s significant efforts to make that not the case.” But the experience of using the drug in Japan could be informative to the FDA in making its approval decision. ‘The longer term studies out of Japan are reassuring, maybe not completely sufficient, but they are reassuring,” Kennedy said.

Ahead of adcomm, FDA discusses Seikagaku's mixed trial results for its lumbar disc herniation injection

Japan-based Seikagaku will face an FDA advisory committee on Friday, with the agency raising concerns ahead of the meeting regarding the efficacy of its condoliase injection for the treatment of radicular leg pain associated with lumbar disc herniation in adults. Ahead of the meeting of the Anesthetic and Analgesic Drug Products Advisory Committee, the FDA notes that one of the clinical trials failed on its primary endpoint. Overall, the agency sounded positive on an approval, noting in briefing documents released Wednesday that “the negative study may inform the benefit-risk assessment for specific populations who may be considered for treatment with condoliase if the product is approved.” One of the three clinical trials evaluated by the FDA did not meet its primary efficacy endpoint (change in worst leg pain from baseline to week 13), nor did it meet either of its two key secondary endpoints, including a pain outcome assessment after a year. The change from worst leg pain from baseline to week 52 slightly favored the control in the failed study, FDA said, but the difference was not statistically significant. The agency also noted that the study that failed likely did so because herniation resulting in symptomatic nerve impingement was not present in most of the patients enrolled, and that’s what the injection targets. The agency said that Seikagaku “performed a detailed analysis to explain the negative U.S. findings despite the positive findings in Study 1031 in Japan.” The company highlighted two key issues: 1) A majority of patients in the failed trial did not have definitive impingement of the nerve root by the disc herniation on an MRI. 2) Baseline back pain was significantly higher in the US study compared to the study in Japan. Two other Phase 3 clinical trials were positive, although one was conducted exclusively in Japan. And in both trials, nerve impingement conducive to condoliase treatment was confirmed by imaging, FDA said. Friday’s committee will have an up-or-down vote on the injection, with the question presented as, “Do the benefits of condoliase injection for treatment of radicular leg pain associated with confirmed nerve root impingement caused by lumbar disc herniation in adults with radicular leg pain outweigh the risks?” Seikagaku, which also markets an intra-articular injection for the treatment of knee osteoarthritis in the US, calls its condoliase injection an improvement on the current treatment landscape, because it does not require general anesthesia and is “less invasive to the patient than surgical treatment.”
