Clinical Trials

Phase 3 trials concluded a while ago and the results are shown below.

Here is an overview of the PRIMROSE-1 (Phase 2b) & PRIMROSE-2 Clinical Trial. The results were outstanding.

Yselty met the primary endpoint for both doses. If approved this gives more options for doctors to prescribe the drug should the patient have an adverse event.

Q. Will ObsEva partner with someone to market and sell Yselty
A. Yes.  According the Elle Investments management has made it an objective to enter into a partnership for Yselty commercialization.

Q. Is Yselty the only UF drug that offers a low dose without Add-Back-Therapy (ABT)?
A. Yes. This is one of OBSV’s dual label goals. Some women are not able to take hormone therapy for do not want to. This lower dose option is designed for that customer group.


The company is burning through cash at a rate of $7M per month. The next catalyst is the FDA submission of Yselty for UF sometime in the 3rd Q. NDA submissions can raise the SP, but usually not by much. FN expects a secondary to occur by the end of the year, which will depress the share price. FN does not see a significant catalyst before these funds are needed.

It is possible after the FDA submission that the FDA requests additional information related to safety. Recall that BMD did decrease slightly with Yselty, but not more than 3%. This will delay FDA approval (if given).

If Yselty gets FDA approval (and we expect it to) the drug will have an uphill battle to take over market share.

Email us at if you have more.  We want to list all risk factors for the drug & trial.


There is considerable competition in the UF and Endometriosis market. Yselty will be arriving 3rd into a crowded space.
AbbVie’s Orilissa is also an oral, once/twice-daily GnRH receptor antagonist for UF. It received FDA approval for endometriosis in July 2018 and launched in the US the following month.
Myovant Sciences produces Relugolix and has a partnership with Pfizer. Myovant is ahead of drug development and will beat Yselty to market. Relugolix will be serious competition for Yselty. More competition info here.
