TRPV1

| ln Vitro |
Vocacapsaicin (CA-008, Conentric Analgesics) – an investigational TRPV agonist being studied for long-lasting pain – works through the same TRPV1 agonism mechanism but its localized delivery is thought to minimize activation of a large array of neurons, such as capsaicin topical products[1].
|
| ln Vivo |
When injected into surgical sites, vocacapsaicin is rapidly converted to lipophilic capsaicin and can cross the membranes to reach the desired amino acid target on TRVP1 channels[1].

| Additional Infomation |
recently completed Phase II clinical trial of vocacapsaicin showed that the drug significantly reduced pain in patients undergoing total knee arthroplasty (TKA). The study was randomized, double-blind, placebo-controlled. All TKA patients received standard treatment, including spinal anesthesia, ketorolac, acetaminophen, and ropivacaine, administered via intra-articular block, femoral nerve block, and IPACK block, respectively. The trial was divided into two intervention groups, receiving 36 mg vocacapsaicin (n = 61) and 60 mg vocacapsaicin (n = 62), respectively, via surgical site infiltration. The control group (n = 64) received standard treatment and, as needed, opioid analgesia. The primary efficacy endpoint was pain reduction recorded using the Numerical Rating Scale (NRS). The NRS uses an 11-point scale, with 0 indicating no pain and 10 indicating unbearable pain. Patients verbally selected a number based on their pain level over the past 24 hours. Table I shows the pain reduction at rest (after administration of 36 mg vocacapsaicin). Table II shows the pain reduction during activity (after administration of 36 mg vocacapsaicin). At 96 and 168 hours post-administration, the opioid dosage was significantly reduced in the vocacapsaicin 36 mg group. Concentric Analgesics noted that the efficacy of the vocacapsaicin 36 mg group was consistently superior to that of the vocacapsaicin 60 mg group. Regarding side effects, all parameters were consistent between the intervention and control groups. No local or systemic safety issues were observed in the Phase II clinical trial.¹⁴ As this research paper has not yet been published, further data interpretation, including inclusion and exclusion criteria, AUC definition, specific adverse events, and their incidence, is not available. We welcome further information to fully evaluate the use of this therapy.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.0158 mL | 10.0790 mL | 20.1580 mL | |
| 5 mM | 0.4032 mL | 2.0158 mL | 4.0316 mL | |
| 10 mM | 0.2016 mL | 1.0079 mL | 2.0158 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
