First Patient Enrolled in Teleflex’s Barrigel™ Rectal Spacer Trial for Post Radical Prostatectomy Radiation Therapy (PPRT)
Randomized, controlled study will be first in personalized spacing evidence to include patients who have a prostate cancer recurrence after prostatectomy.
WAYNE, Pa., Oct. 29, 2024 (GLOBE NEWSWIRE) — Teleflex Incorporated (NYSE: TFX), a leading global provider of medical technologies, today announced the first patient enrolled in the latest Barrigel™ rectal spacer randomized, controlled, single-blinded multicenter study: The PPRT Trial.
Barrigel™ rectal spacer is the first and only sculptable hyaluronic acid rectal spacer designed to significantly reduce radiation that reaches the rectum during prostate radiation therapy.1-3 This new study will evaluate Barrigel™ rectal spacer in patients undergoing hypofractionated post-prostatectomy radiation therapy across sites in the U.S. and one site in Australia.
“Our first enrolled patient represents a significant milestone as we grow our body of clinical evidence for Barrigel™ rectal spacer with patients undergoing radiation therapy after a prior prostatectomy,” said Martin T. King, MD, PhD, Radiation Oncologist with the Dana-Farber Brigham Cancer Center, Harvard Medical School Assistant Professor of Radiation Oncology, and principal investigator of the study.* “Our study endpoints are to demonstrate Barrigel™ rectal spacer as a safe and effective option that reduces prostate radiation side effects for this patient population.”
Based on the segmentation of risk groups between low, medium and high, prostate cancer reoccurrence after radical prostatectomy ranges from 16 to 46 percent.4
Rectal spacers are used during prostate cancer radiation therapy to enable effective radiation dosage to the prostate while sparing healthy rectal tissue. This is especially important in hypofractionated treatment regimens, in which radiation is delivered at higher doses over a fewer number of treatment sessions. Unlike other rectal spacers made from different materials, which harden almost immediately after administration, the hyaluronic acid in Barrigel™ rectal spacer remains soft and pliable. This gives physicians time to sculpt, layer, and add more Barrigel™ rectal spacer as needed to optimize rectal protection.1,5-7 Additionally, Barrigel™ rectal spacer is highly visible in real time using transrectal ultrasound, which helps to ensure optimal spacing.1,5-7
“Scientific evidence serves as the cornerstone for the advancement and expansion of medical technologies, fostering trust between clinicians and patients,” stated Michael Chao, MD, a Radiation Oncologist at the Olivia Newton John Cancer Wellness & Research Centre in Victoria, Australia.* “I take great pride in being the first physician to treat a patient in this clinical trial.”
Study sites will enroll patients who have:
- Undergone nerve-sparing prostatectomy (intrafascial)
- No radiographic evidence of local, regional, or distant metastatic disease via (PSMA) PET imaging
- An intact facial layer to support the Barrigel™ rectal spacer
- Had six months of androgen deprivation therapy, a first-line treatment for advanced prostate cancer
About Barrigel™ Rectal Spacer
Barrigel™ rectal spacer is the first and only hyaluronic acid rectal spacer that separates the prostate from the rectum to protect the rectum during radiation therapy treatment for prostate cancer.1 Barrigel™ rectal spacer is made from Non-Animal Stabilized Hyaluronic Acid (NASHA).8
Hyaluronic acid is a substance naturally present in the human body and is highly biocompatible and fully absorbable. NASHA has a proven history of safety and efficacy in a wide variety of medical applications in men, women and children worldwide.5,9
Barrigel™ rectal spacer has been proven to significantly reduce unwanted side effects from prostate cancer radiation therapy and is approved for rectal spacing in the United States, Australia, and Europe. Barrigel™ rectal spacer can be used for prostate cancer patients with T1-T3b disease.

Barrigel™ Rectal Spacer Important Safety Information
Barrigel™ rectal spacer is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and, in creating this space, it is the intent of Barrigel™ rectal spacer to reduce the radiation dose delivered to the anterior rectum. Barrigel™ rectal spacer is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment and is intended to be absorbed by the patient’s body over time.
Barrigel™ rectal spacer should only be administered by qualified and properly trained physicians with experience in ultrasound guidance and injection techniques in the urogenital/pelvic area.
As with any medical treatment, there are some risks involved with the use of Barrigel™ rectal spacer. Potential complications associated with the use of Barrigel™ rectal spacer include, but are not limited to: pain associated with Barrigel™ rectal spacer injection; needle penetration of the bladder, prostate, rectal wall, rectum, or urethra; injection of Barrigel™ rectal spacer into the bladder, prostate, rectal wall, rectum, urethra, or intravascularly; local inflammatory reactions; infection; urinary retention; rectal mucosal damage, ulcers, necrosis; bleeding; constipation; and rectal urgency. More information on indications, contraindications, warnings and instructions for use can be found in the Instructions For Use at www.barrigel.com.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
