Our Current Studies

Do you have high blood pressure?

Holdsworth House Medical Practice is now recruiting for a study for patients with high blood pressure, comparing the benefits of taking:

  • four low dose medications in one pill, versus
  • one normal dose pill

If you are over 18 and taking only one hypertension medication, or none at all, and your blood pressure is not well controlled you may be eligible for this study.

All study assessments and medication are supplied at no cost.

For more information please contact our Research department on 02 8038 1044 or email us at

Endometriosis pain?

You may be eligible for a clinical trial.

Do you have moderate to severe pelvic pain caused by endometriosis? Endometriosis affects
about 10% of women — approximately 176 million women worldwide — and has no known
cause or cure. We are currently participating in a clinical research study which is evaluating an
investigational non-hormonal medication to see if it is safe and effective in reducing moderate to
severe endometriosis-related pelvic pain.

You may qualify for this study if you:
• Are a woman who is 18 to 49 years old
• Have been surgically diagnosed (via laparoscopy or laparotomy) with endometriosis within the past 10 years
• Experience endometriosis-related pelvic pain, even when you are not having your period
• Have regular menstrual cycles of 24 to 38 days
• Meet additional requirements, which the study team will discuss with you

To learn more about the possible risks and benefits of participation or to see if you may qualify for this study, contact our Research department on 02 8038 1044 or email us at

Information for Patients

For any questions or information that is not provided below please contact our friendly research team.

Generally our research unit only take part in later phase studies where the drug or treatment has already been extensively tested in both laboratories and humans for side effects.

Before consenting to any clinical trial, potential participants are given very detailed information about what the study will involve and the possible risks and side effects. This information is approved by an independent ethics committee who ensure that the patient’s safety and care is considered above all study activities.

During a study participants see one of our Doctors at every visit and are monitored carefully for any ill-effects or reactions to the study treatment.
Sponsors respect the privacy of study participants and safeguard the confidentiality of their medical information in accordance with all applicable laws and regulations. While access to confidential medical records may at times be necessary to verify clinical information, no information that identifies individual participants is retained by Sponsors.
Participation in a clinical trial is completely voluntary and participants may withdraw from a study at any time.
In most cases, there is no cost to you to participate in a clinical trial. Your medication, treatment and medical appointments relating to the study will be free of charge. However, you will be required to attend the clinic at regular intervals and in certain instances there may be compensation available for time and travel expenses.
