Oyster Therapeutics: State Of Business Is Confounding
OYST has an approved product that is highly competitive against a blockbuster drug.
They seem to have executed commercialization pretty well, except in the bottom line.
Here, they have abysmally failed to make any money.
Oyster Point Pharma, Inc. (OYST) has an approved product, Tyrvaya (OC-01, varenicline solution) Nasal Spray for treating dry eye disease, and it is also in the pipeline for Neurotrophic Keratopathy Stage 1. NK is a rare disease characterized by decreased corneal sensitivity and poor corneal healing. For the pipeline program, the company says in its earnings call:
We continue to enroll patients in our OLYMPIA Phase 2 study of OC-01 nasal spray aimed at treating Stage 1 NK. We remain on track to expect results of this trial in the second half of this year.
Now, coming to the approval, Tyrvaya was approved in October 2021 and started in the market by early November. So this was effectively the first full quarter of reported earnings for Tyrvaya.
Dry eye disease occurs in over 38 million Americans. Current treatment options are Allergan’s Restasis and Shire’s Xiidra; both are given as eye drops. Restasis is a mild immunosuppressant while Xiidra is an anti-inflammatory drug. However, given the formulation that requires giving the medications directly to the eye - always a cumbersome and painful process - compliance is low. Moreover, these therapies take months to work from the onset of treatment. The company says there are 7 million patients that have tried and abandoned the standard therapies.
Tyrvaya uses a completely new delivery method, as well as a unique mechanism of action. It is used as a nasal drop, and it works by triggering the trigeminal nerve which in its turn triggers tear production. In 3 clinical trials in over 1000 patients in mild, moderate and severe dry eye disease - ONSET-1, ONSET-2 and MYSTIC - the drug has demonstrated safety and efficacy. Patients showed statistically significant improvements in tear film production as assessed using the Schirmer's score at Week 4, with more than 50% patients showing optimal tear production compared to about half that number in the placebo group:
TYRVAYA-treated patients showed statistically significant improvements in tear film production as assessed using the anesthetized Schirmer's score (0-35 mm) at Week 4. Of the patients treated with TYRVAYA, 52% achieved ≥10 mm increase in Schirmer's score from baseline in the ONSET-1 study, and 47% achieved ≥10 mm increase in Schirmer's score from baseline in the ONSET-2 study, compared to 14% and 28% of vehicle-treated patients in the ONSET-1 study and the ONSET-2 study, respectively at Week 4 (p<0.01 in both studies). Of the patients treated with TYRVAYA, the mean change in Schirmer's score was 11.7 mm and 11.3 mm as compared to 3.2 mm and 6.3 mm in the vehicle treated patients in the ONSET-1 study and ONSET-2 study, respectively at Week 4.
So the first full quarter revenue is $2.7mn. Around 19,000 prescriptions were filled, and these were written by 4500 unique prescribers. 65% of all patients went for refills. A number of patients have continued using the medicine for 6 months starting from November.
The company has also taken great strides on the mediclaim front. In February, TYRVAYA was placed on Express Scripts National Preferred basic and high performance formularies, which collectively make up around 26 million lives. The company has gone on to add more payers, and now it has commercial coverage for up to approximately 95 million lives, which represents 52% of all U.S. commercial lives.
Financials
OYST has a market cap of $134mn and a cash balance of $144mn. This is a terrible state of affairs. There’s a short interest of 22%, which says that the market still thinks the company is overvalued. For a commercial stage company with a clinically successful drug to be in this sorry state is unnerving for investors.
