Who is eligible?

Here at MAC Clinical Research we are currently running a trial to test a new treatment for depression and erectile dysfunction (ED). You must have depression and ED to take part in this study and not currently taking any depression treatment.

Depression is a low mood disorder where a person will be persistently feeling sad and experience loss of interest. These feelings, thoughts and behaviours can lead to a variety of emotional and physical illnesses (including sexual problems).

Erectile dysfunction or erectile problems are terms used to describe when a man is unable to develop or sustain an erection, which can lead to difficulties in having sexual intercourse and low libido.

The study drug is a new compound which works by enhancing the effects of substances in the body such as serotonin and dopamine to help stimulate an erection. The study drug is being developed in the hope that it will treat depression and ED in men for whom current treatments either do not work or are poorly tolerated.

The main aims of this study are:

  • To assess the effect of the study drug on the body
  • To assess the safety and tolerability of the study drug
  • To see how the body absorbs and removes the study drug


If you are eligible following medical screening, you will receive 2 doses of study medication and one dose of placebo. You will be required to attend 6 visits to the MAC Manchester clinic and on 4 occasions you will be asked to apply a Rigiscan device to your penis.  This is a piece of equipment which measures the strength of the erection you get whilst watching an “Adult” film in a private room.

A full description of the study will be given before you decide to take part, both over the phone and during an appointment at the MAC clinic. This will include you receiving the full patient information sheet (PIS). Your GP will also be notified of your participation.
