FREEHOLD, N.J., Dec. 20, 2024 (GLOBE NEWSWIRE) -- Channel Therapeutics Corporation, (“Channel” or the “Company”), (NYSE American: CHRO), a pioneer in the development of non-opioid pain treatment therapeutics, is providing a statement regarding Vertex Pharmaceutical’s recently announced Phase 2 data of Suzetrigine, an investigational, oral, highly selective NaV1.8 pain signal inhibitor in people with painful lumbosacral radiculopathy.

“We are encouraged to see that the product will advance to Phase 3 trials in painful lumbosacral radiculopathy, pending discussions with regulators,” said Eric Lang, Channel’s Chief Medical Officer. “While both NaV1.7 and NaV1.8 are voltage-gated sodium channels mainly expressed in sensory neurons, there are important differences in their roles in pain transmission. Research indicates that an over expression of NaV1.8 leads to moderate pain whereas an overexpression of NaV1.7 leads to debilitating pain morbidities, and we believe that NaV1.7 inhibition may be a more potent therapy for pain treatment.”

Characteristics of Selective NaV1.7 Inhibition

  • NaV1.7 is a well-studied drug target with strong genetic validation — studies of inheritable pain disorders demonstrate that the spectrum of NaV1.7 activity validates the importance of this target.

  • Lack of NaV1.7 activity leads to the inability to sense pain, whereas NaV1.7 gain of function leads to severe pain. Modulation of NaV1.7, therefore, should be an effective mechanism for decreasing pain.

“Channel Therapeutics has chosen a three-pronged approach for our NaV1.7 molecule to demonstrate the utility of this target. We are utilizing an oral NaV1.7 inhibitor for the potential treatment of neuropathic pain starting with Idiopathic Small Fiber neuropathy and Erythromelalgia, a novel eye drop formulation of a NaV1.7 inhibitor to treat eye pain and a novel slow-release depot formulation NaV1.7 inhibitor for post-surgical nerve blocks,” stated Frank Knuettel II, Chief Executive Officer of Channel. “The important differences between NaV1.7 and NaV1.8 not only informs but also differentiates Channel Therapeutics’ approaches to clinical development of the Company’s selective sodium channel blockers CC8464, CT2000 and CT3000. We are very encouraged by the recent data that we have seen from our ongoing programs, including the results from our in vivo nerve block results published earlier this week. As such, we look forward to the upcoming studies and data readouts in 2025 which will serve as critical milestones for which to further substantiate the merits of Channel’s clinical development plan,” Mr. Knuettel concluded.
