Sorrento Receives FDA Approval For ZTlido Which Had A Long Road To Approval


  • Sorrento Therapeutics receives FDA approval for ZTlido treating patients with post-herpetic neuralgia also known as post-shingles pain.
  • ZTlido will compete with Endo Pharmaceuticals Lidoderm as soon as it hits the market.
  • ZTlido provides an advantage over other patch treatments in that it has better adhesion properties.
  • ZTlido is a non-opioid which makes it a good treatment option for these patients with post-shingles pain.
  • Financials will need to be kept above $8 million in unrestricted U.S. cash at all times so the company maintains its loan agreement with Hercules.

Recently, Sorrento Therapeutics (SRNE) announced that it had received FDA Approval for its pain patch ZTlido. This patch was approved by the FDA for the relief of pain associated with post-herpetic neuralgia (PHN). Another way to think of this is as post-shingles pain. The stock has traded lower since then, but I believe it offers a great buying opportunity. The reason being is because this pain patch is expected to generate peak sales of over $1 billion. Therefore, there is plenty of room for share price appreciation. Especially, since its market cap only stands at $705 million.

FDA Approval

The FDA approval for ZTlido is a huge game changer for Sorrento Therapeutics. That's because it can now go after a large market. But besides that point, there is one substantial difference between it and many other pain treatments. That difference being that ZTlido is a non-opioid. One thing to note is that there are no opioid drugs approved by the FDA for PHN. However, opioid drugs are still used for PHN off-label as first-line treatment. This now provides a way for doctors to treat this indication through the use of a non-opioid which is safer for patients. The ZTildo patch is expected to compete with Endo Pharmaceuticals (OTCPK:ENDO) Lidoderm. With Endo already establishing such a foothold in this market, how is Sorrento going to compete? Well, I will tell you one way it won't compete it in and that is in terms of efficacy. Both ZTildo and Lidoderm perform pretty much in the same fashion. The difference, believe it or not, will come in terms of adhesion. Further research online shows that patients have trouble with the adhesion properties of Lidoderm. That means that the patch hardly stays on when a patient needs to use it. Well, ZTildo has better adhesion properties. I believe that because of this it will perform
