Sorrento Therapeutics Subsidiary, Scilex, Receives US FDA Approval for Non-Opioid ZTlido™ (lidocaine topical system) 1.8% for PHN Pain
“ZTlido was designed to solve a problem that is commonly reported with transdermal/topical patches: they don’t stay on. Based on the adhesion study results with ZTlido, we believe that ZTlido product will be welcomed by healthcare providers, patients and payers who are looking for an effective and efficient, local pain treatment,” said Dr.
“Topical lidocaine is an important option for healthcare providers to have in their armamentarium for treating PHN, a difficult-to-treat neuropathic pain,” stated Dr.
ZTlido’s anhydrous topical system is based on a novel technology that is designed to achieve superior adhesion and drug delivery efficiency. ZTlido™ only requires 36 mg/topical system versus 700 mg/patch of Lidoderm® (lidocaine patch 5%), the US reference product, to achieve the same therapeutic dose of drug. The safety and efficacy of ZTlido was bridged to Lidoderm in comparative pharmacokinetic studies that demonstrated bioequivalence between products.
According to an
In a separate Phase 1 comparative adhesion study in normal healthy subjects (n=44), ZTlido demonstrated superior adhesion (p <0.0001) to Lidoderm at 3 hours that improved over the 12-hour administration period.
According to recent IMS data, more than 100 million prescription lidocaine patches were sold in the US in 2017. Sorrento intends to have Scilex complete the final steps necessary to commercial launch of ZTlido in the US with the objective to make the product commercially available to patients sometime in 2018.
About ZTlido™ (lidocaine topical system 1.8%)
ZTlido™ is comprised of a non-aqueous adhesive material containing 1.8% lidocaine, which is applied to a non-woven polyester felt backing and covered with a polyethylene terephthalate (PET) film release liner. The release liner is perforated in the middle and removed prior to application to the skin. The size of the topical system is 10 cm × 14 cm x 0.08 cm thick. ZTlido is indicated for relief of pain associated with post-herpetic neuralgia. It should be applied only to intact skin.
During or immediately after treatment with ZTlido, the skin at the site of application may develop blisters, bruising, burning sensation, depigmentation, dermatitis, discoloration, edema, erosions, erythema, exfoliation, flushing, irritation, papules, petechia, pruritus, vesicles, or may be the locus of abnormal sensation. These reactions are generally mild and transient, resolving spontaneously within a few minutes to hours.
Allergic and anaphylactoid reactions associated with lidocaine, although rare, can occur. They are characterized by angioedema, bronchospasm, dermatitis, dyspnea, hypersensitivity, laryngospasm, pruritus, shock, and urticaria. If they occur, they should be managed by conventional means.
Due to the nature and limitation of spontaneous reports in post-marketing surveillance, causality has not been established for additional reported adverse events including: Asthenia, confusion, disorientation, dizziness, headache, hyperesthesia, hypoesthesia, lightheadedness, metallic taste, nausea, nervousness, pain exacerbated, paresthesia, somnolence, taste alteration, vomiting, visual disturbances such as blurred vision, flushing, tinnitus, and tremor.
Systemic adverse reactions following appropriate use of ZTlido are unlikely, due to the small dose absorbed. Systemic adverse effects of lidocaine are similar in nature to those observed with other amide local anesthetic agents, including CNS excitation and/or depression (light headedness, nervousness, apprehension, euphoria, confusion, dizziness, drowsiness, tinnitus, blurred or double vision, vomiting, sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness, respiratory depression and arrest). Excitatory CNS reactions may be brief or not occur at all, in which case the first manifestation may be drowsiness merging into unconsciousness. Cardiovascular manifestations may include bradycardia, hypotension and cardiovascular collapse leading to arrest.
Scilex, a majority-owned subsidiary of Sorrento located in
Sorrento is a clinical stage, antibody-centric, biopharmaceutical company developing new therapies to turn malignant cancers into manageable and possibly curable diseases. Sorrento’s multimodal multipronged approach to fighting cancer is made possible by its’ extensive immuno-oncology platforms, including key assets such as fully human antibodies (“G-MAB™ library”), clinical stage immuno-cellular therapies (“CAR-T”), intracellular targeting antibodies (“iTAbs”), antibody-drug conjugates (“ADC”), and clinical stage oncolytic virus (“Sephrevir®”).
Sorrento’s commitment to life-enhancing therapies for cancer patients is also demonstrated by our effort to advance a first-in-class (TRPV1 agonist) non-opioid pain management small molecule in Resiniferatoxin (“RTX”) and ZTlido. Resiniferatoxin is completing a phase IB trial in terminal cancer patients.
