Scilex Holding Company, a majority-owned subsidiary of Sorrento Therapeutics, Inc., Announces Final Results for SP-102 (SEMDEXA™) Efficacy and Safety from its Pivotal Phase 3 Clinical Trial Program for Sciatica Pain Management Supporting the Potential for First to Market Opportunity

Rhea-AI Summary

Scilex Holding Company announced positive results from its SP-102 (SEMDEXA™) Phase 3 C.L.E.A.R. trial, involving 401 patients with radiculopathy. The trial showed significant pain relief with a mean difference of -1.08 against placebo (p < 0.001) in just four weeks. SP-102 demonstrated sustained effects, with a median time to repeat injection reaching 99 days. Improvement in disability, as measured by the Oswestry Disability Index, reached 28%. The product, which received FDA Fast Track status, boasts a clean safety profile with no serious adverse events linked to the treatment.

Positive

• SP-102 (SEMDEXA™) achieved a statistically significant mean pain reduction of -1.08 (p < 0.001) over four weeks compared to placebo.
• The trial documented a 28% improvement in the Oswestry Disability Index, surpassing the minimal clinically meaningful improvement.
• Sustained pain relief was observed, with a median time of 99 days to repeat injection indicated.
• The safety profile was excellent, with no serious adverse events or injection-related complications reported.

Negative

• None.

• SP-102 (SEMDEXA™), with 401 patients enrolled in the C.L.E.A.R. trial (Corticosteroid Lumbosacral Epidural Analgesia in Radiculopathy), experienced a rapid onset of pain relief, measured by Numeric Pain Rating Scale of average daily pain in the affected leg, with highly statistically significant improvement against placebo over the first 4 weeks, following a single transforaminal injection, LS Mean (SEM) difference -1.08 (0.17), with a p-value < 0.001.
  
  
• SP-102 (SEMDEXA™) showed continued reduction of pain beyond one month, and the median time to open-label repeat injection was 99 days (95% CI: 78, 129 days) according to a Kaplan-Meier estimation. By contrast, off-label injectable steroids typically provide pain relief for periods ranging from less than a week and up to one month, and then a repeat injection may be required.
• The key secondary endpoint of Oswestry Disability Index, the gold standard for measuring degree of disability and estimating quality of life, showed a 28% improvement at 4 weeks on SP-102 (SEMDEXA™) compared to baseline (minimal clinically meaningful improvement 8%-12%)¹⁵. The LS Mean (SEM) difference as compared to placebo was -6.28 (1.49), with a p-value < 0.001.
• Safety analysis demonstrated a very clean safety profile with no identified safety risks. There were no serious adverse events related to the drug or injection procedure, and no adverse events of special interest reported, such as hematoma and infection at the injection site, or paraplegia. These events are associated with the off-label use of non-approved injectable steroid preparations. The C.L.E.A.R trial also established the safety of repeat injections, as patients who experienced moderate-to-severe radicular pain between 4 and 23 weeks were allowed to receive open-label additional SP-102 (SEMDEXA™) injection. The safety analysis was comparable between treatment groups through 4, 12 and 24 weeks of study period.

PALO ALTO, Calif., March 18, 2022 (GLOBE NEWSWIRE) -- Scilex Holding Company (“Scilex”), a majority-owned subsidiary of Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”), today announced highly significant positive final results from its SP-102 (SEMDEXA™) Phase 3 Pivotal Trial C.L.E.A.R. Program. SP-102 (SEMDEXA™) has received Fast Track status from the FDA.

The C.L.E.A.R. Trial (Corticosteroid Lumbosacral Epidural Analgesia for Radiculopathy) was designed to investigate safety and analgesic effects of a single and repeat transforaminal injections of SP-102 (SEMDEXA™) compared to placebo (saline injection). The trial enrolled 401 low back pain subjects with unilateral intervertebral disc herniation in lumbar spine resulting in radicular pain symptoms of moderate to severe leg pain. It is the largest known randomized well-controlled trial in sciatica using epidural steroid injections. The primary endpoint of change in average daily pain in the affected leg over 4 weeks following the initial injection demonstrated LS Mean (SEM) group difference of -1.08 (0.17) compared to placebo with a p-value <0.001. SP-102 (SEMDEXA™) is the first non-opioid novel injectable corticosteroid gel formulation product in development for the treatment of lumbar radicular pain, and it contains no preservatives, surfactants, solvents, or particulates.

The key secondary endpoint of Oswestry Disability Index, the gold standard for measuring degree of disability and estimating quality of life, showed a 28% improvement at 4 weeks on SEMDEXA™ compared to baseline (minimal clinically meaningful improvement 8%-12%)¹⁵. The LS (Lest Square) Mean (Standard Error of Means) difference as compared to placebo was -6.28 (1.49), with a p-value < 0.001.

SP-102 (SEMDEXA™) demonstrated pain relief that continued through 12 weeks. Other pain measurements, such as worst daily and current pain in the affected leg and average daily pain in lower back, demonstrated statistically significant results compared to placebo. Most of the other secondary endpoints in hierarchical arrangement for sequential testing procedure also demonstrated statistically significant results, and included Global Impression of Change, Brief Pain Inventory, PainDETECT, and cumulative use rescue medications (acetaminophen).      

Safety analysis demonstrated a very clean safety profile with no identified safety risks. There were no serious adverse events related to the drug or injection procedure, and no adverse events of special interest reported, such as hematoma and infection at the injection site, or paraplegia. These events are associated with the off-label use of non-approved steroid preparations. The C.L.E.A.R trial had also established safety of repeat injections, as patients who experienced moderate-to-severe radicular pain between 4 and 23 weeks were allowed to receive open-label additional SP-102 (SEMDEXA™) injection. The safety analysis was comparable between treatment groups through 4, 12 and 24 weeks of study period.

“We are very pleased with the positive outcome and these trial results are very remarkable. They will impact greatly the pain management community and will enable us to proceed with our plans for registering SP-102 (SEMDEXA™) with the FDA for the treatment of subacute lumbosacral radicular pain. We believe SP-102 (SEMDEXA™) has the potential to be a transformative treatment option for sciatica, an area that has not seen any significant advancement in therapies that patients and physicians have been seeking for decades. We plan to present the results from the Phase 3 C.L.E.A.R trial at upcoming scientific conferences and submit for publication in a peer-reviewed journal,” said Dmitri Lissin, MD, Chief Medical Officer of Scilex.

Scilex intends to use the results from this pivotal Phase 3 trial to discuss with the FDA in 2022 licensure application requirements and Breakthrough Designation Status for the high unmet need sciatica indication for which no treatments have been approved in the U.S. Scilex has extensive clinical and pre-clinical data (including multiple Phase 2 clinical trials) with the novel viscous gel formulation of SP-102 (SEMDEXA™), which was designed to provide extended local effect and non-opioid pain relief for sciatica patients. Scilex expects to present the robust data collected over the course of the company’s multi-year clinical development program to the FDA as part of a New Drug Application (NDA).

More than 60% of U.S. opioid prescriptions are for the treatment of chronic low back pain (CLBP)¹ despite the fact that opioids are associated with serious and potentially life-threatening side effects and have not demonstrated efficacy in the treatment of CLBP.^2,3,4 In 2018, more than 67,000 drug overdose deaths occurred in the United States⁵ of which almost 47,000 (70%) were opioid related. Over 70% of the 70,630 deaths in 2019 involved an opioid.⁶ Provisional data release by the Centers for Disease Control and Prevention showed drug overdose deaths rose by nearly 29% over a 12-month period ending in April 2021, to an estimated 100,306.⁷

“We are delighted with these highly significant positive clinical results for the pivotal SP-102 (SEMDEXA™) Phase 3 trial and this may provide encouraging news for the many millions of people worldwide who are confronting painful radicular pain (sciatica). We believe that SP-102 (SEMDEXA™) could be the first FDA-approved epidural steroid gel injection product for patients suffering from this common, very painful condition. I really appreciate the work of the Scilex team and their passion for addressing America's opioid crisis and in continuing our mission to improve our ability to help millions of patients dealing with acute and chronic pain issues, in exciting new ways. These final data results mark an exciting and important milestone in our journey to become the premier non-opioid pain management company,” said Jaisim Shah, President and Chief Executive Officer of Scilex.

SP-102 (SEMDEXA™) is the first non-opioid novel injectable corticosteroid gel formulation product in development for the treatment of lumbar radicular pain, and it contains no preservatives, surfactants, solvents, or particulates. If approved by the FDA, the SP-102 (SEMDEXA™) formulation will be available in a pre-filled syringe formulation and will be administered as an epidural injection for the treatment of sciatica. Based on preclinical and clinical studies, SP-102 (SEMDEXA™) extends the residency time at the site of injection and does not show the safety concerns that led the FDA to warn against using other injectable steroid formulations by the epidural route of administration.

While off-label used steroids provide pain relief for periods ranging from less than a week and up to one month, after which a repeat injection may be required, SP-102 (SEMDEXA™) showed continued reduction of pain beyond one month, and the median time to open-label repeat injection was 99 days (95% CI: 78, 129 days) according to Kaplan-Meier estimation.

By 2022, the overall estimated number of epidural steroid injection (ESI) procedures in the U.S. is expected to be 12.1 million across all Medicare and private coverage patients, with lumbar radiculopathy/sciatica procedures comprising approximately 88% of all ESIs administered, according to a proprietary study by Syneos Health Consulting. Despite widespread utilization of ESIs, concerns persist in the market about particulate steroids and potential side effect and safety concerns (e.g., stroke) from current off-label use. As a result, a significant unmet medical need exists within the market for a novel, non-particulate ESI formulation that demonstrates safety and effectiveness in controlled clinical trial evaluations.¹⁴

In the U.S., more than 30 million people suffer from low back and radicular pain. This population is expected to grow as the overall population ages.^8,9 Many patients experience moderate to severe pain with intolerance of and/or inadequate response to current analgesic therapies such as opioids and nonsteroidal anti-inflammatory drugs (NSAIDs).^10,11 There is a great need for highly effective analgesic medications to provide patient relief without the toxicity and tolerability challenges of NSAIDs and opioids.⁹  

Scilex Holding Company and Vickers Vantage Corp. I (Nasdaq: VCKA) (“VCKA”), a special purpose acquisition company sponsored by Vickers Venture Fund VI Pte Ltd and Vickers Venture Fund VI (Plan) Pte Ltd, have entered into a definitive business combination agreement ("BCA"). Upon closing of the transaction, the combined company (the “Combined Company”) will be renamed Scilex Holding Company, and its common stock is expected to be listed on Nasdaq under the ticker symbol “SCLX”.
