Analysis Focus: SAGE

Sage Therapeutics (SAGE) will follow an accelerated plan to develop its GABA modulator SAGE-217. This follows an earlier Breakthrough Therapy meeting with the FDA. The candidate is being tested on conditions of major depressive disorder (NYSEARCA:MDD) and postpartum depression (NYSE:PPD).

Earlier in May, Brexanolone IV (SAGE-547), Sage's lead product candidate, an intravenous formulation of brexanolone for the treatment of PPD, received FDA Priority Review status. PDUFA is set on December 19, 2018. If approved, brexanolone IV may become the first and only medication indicated for the treatment of PPD. Recent developments regarding SAGE-217 makes the company's lead in the category even stronger.

Due to the successful Breakthrough Therapy meeting only a single additional Phase 3 study in MDD and the ongoing Phase 2 study in PPD will be sufficient to provide key data to support a U.S. marketing application. Phase2 PP trial data is expected by Q4 while Phase 3 MDD study will launch in H2.

All recent data show a very high rate of prevalence of MDD among various cross sections of US populations. The condition is often manifested in incidence of anhedonia, depressed mood, or feeling of hopelessness and meets five of the 9 DSM-5 MDD criteria. The lifetime prevalence of MDD was 20.6%. According to a study published in JAMA Psychiatry, approximately half of lifetime cases of MDD were considered severe (49.5%) and 39.7% were moderate in nature.

It is almost impossible to determine the rate of incidence of PPD. However, it is estimated that approximately 70%- 80% of women experience some form of baby blues and many more go through a more severe condition of postpartum depression and its other subtypes. ~4 million live births/year occur in the U.S. That takes the possible number of postpartum depression diagnoses to ~600K individuals. There are no approved therapies for PPD, and there is a clear unmet medical need for treatment. In recognition of that, Brexanolone IV had received Breakthrough Therapy Designation in September 2016.

Sage had a follow on offering in February 2018. The offer garnered the company ~$1.1 billion in cash. Though the accelerated development plan shortens the last stage trials considerably, SAGE-217 still has quite some length to complete. However, the cash position compared to the existing and projected burn rate does not face the prospect of near-term cash crunch. Seemingly for SAGE there are no serious catalysts on the way before the end of the year and that should allow the stock to have even more room. In spite of its ~20% increase to $175.76 yesterday, the stock is still behind its 52 wk high of $195.97. This seems to be a buy proposition ahead of the PDUFA.

Stocks in the News: GSGTF, AZN, LLY

GenSight Biologics reports data from Phase III clinical trial of GS010 for treatment of LHON

Discussion: GenSight Biologics (OTC:GSGTF) reported additional results from Phase III clinical trial evaluating the safety and efficacy of a single intravitreal injection of GS010 (rAAV2/2-ND4). The candidates was tested in 37 subjects whose visual loss due to 11778-ND4 Leber Hereditary Optic Neuropathy (LHON) commenced between 6 and 12 months prior to study treatment. Earlier top-line results failed to meet primary endpoints in April. The same trial successfully met secondary endpoints. The company presented the full set of data and offer post hoc findings at a Key Opinion Leader Event in New York City. Following trial protocol all 37 subjects will be tested again at 96 weeks, and accordingly new data set will be reported in Q1 2019.

LHON is a condition in which bilateral, painless subacute loss of central vision occurs during young adult life. Symptoms begin early and usually in one eye. This is followed a few weeks later by visual failure in the other eye. In extremely rare cases neurologic abnormalities, such as peripheral neuropathy, postural tremor, nonspecific myopathy, and movement disorders may also occur. This rare disease is caused by mutations in mitochondrial DNA and it is transmitted by maternal inheritance. LHON affects ~1:50,000 people. Many carriers of the disease does not suffer from any visual loss.

Lilly and AstraZeneca bail on AD candidate lanabecestat

Discussion: An independent data monitoring committee determined that both the late studies of lanabecestat were unlikely to meet the primary endpoints of the trial. Lanabecestat is a BACE inhibitor for the treatment of Alzheimer's disease (AD). AstraZeneca (NYSE:AZN) and Eli Lilly (NYSE:LLY) were developing the candidate. This is the third in the recent chain of setback for development of BACE inhibition. Apparently, the therapy development is facing a rough patch in recent times. Earlier, Johnson & Johnson (NYSE:JNJ) and Merck (NYSE:MRK) had bailed out their candidates atabecestat and verubecestat, respectively. The former was abandoned due to toxicity concerns while the latter had no definite efficacy data to continue.

AD is the leading contributor (accounting for up to 75% of all cases of dementia) to the global phenomenon of dementia among the elderly. Many consider the disease to be reaching an epidemic proportion. As the projected elderly population is expected to see a rise to 12% of the total population and touching ~1B in 2030, AD remains at the core of the concern for the elderly. Hence any significant pharmacological development in improving the conditions of AD has a significantly long term impact. Having said that, this one negative component in AZN and LLY's long and strong pipeline doesn't really dent either of the stock's standing.
