About this study
Official title: Phase 1 Study of Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) and Electrostatic PIPAC (ePIPAC) With Paclitaxel for Peritoneal Carcinomatosis - PIPAC2 Study
Peritoneal carcinomatosis (PC) is a miserable disease with poor treatment outcome. Intraperitoneal administration of anticancer drugs enables an extremely high concentration of drugs to directly contact the target cancer lesions in the peritoneal cavity. However, its effectiveness is limited by the intraperitoneal distribution and penetration of the drug. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is an innovative intraperitoneal chemotherapy concept that enhances efficacy by taking advantage of the physical properties of gas and pressure. Electrostatic precipitation pressurized intraperitoneal aerosol chemotherapy (ePIPAC) may further enhance these benefits.
This research study serves to determine the safety profile and tolerability of PIPAC/ePIPAC with paclitaxel. It will determine the maximal tolerated dose (MTD) and evaluate the safety and tolerability, and pharmacokinetics of PIPAC/ePIPAC paclitaxel in pre-treated patients with peritoneal carcinomatosis (PC). It may offer a novel and effective option of treatment for patients with PC, who, at present have limited options involving the use of systemic chemotherapy and who suffer from poor life expectancy and poor quality of life.
Read the detailed description
In patients with histologically proven unresectable or recurrent gastric cancer limited to the peritoneum, the combination of intraperitoneal (IP) paclitaxel with systemic chemotherapy reported a one-year survival rate of 78%. However, the effectiveness of IP chemotherapy may be limited by its distribution, tissue penetration and associated catheter-related complications.
Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) is a novel drug delivery technique for PC taking advantage of physical laws (gaseous nature, hydrostatic pressure) with superior pharmacological properties (homogeneous distribution, deeper tissue penetration). It is applied through laparoscopy and is minimally invasive. Adding electrostatic loading (ePIPAC) as an adjunct would further improve the pharmacological properties of PIPAC since it should induce precipitation of the aerosolized drug, increasing the ratio between the dose applied and the dose in the target tissue.
Systemic toxicity is significantly reduced due to the peritoneum/blood barrier and the low dose applied (about 20% of the usual systemic dose). A systematic review highlighted that PIPAC combines the benefits of a minimally invasive approach with pharmacokinetic advantages of intraperitoneal administration and pressurized vaporization. It concluded that PIPAC is feasible, safe, and warrants further prospective studies. PIPAC may be combined with systemic palliative chemotherapy with minimal additional organ toxicity. This method of treatment avoids the morbidity and mortality of HIPEC. PIPAC has been shown in pre-clinical studies to be potentially more efficacious than catheter-based IP-chemotherapy due to better drug distribution and penetration. In clinical use, PIPAC can be repeated at intervals of 6 weeks to 3 months. This allows repeated objective assessment of therapy effect over time.
To date, PIPAC has only been utilized to administer Oxaliplatin or a combination of Doxorubicin/Cisplatin. Paclitaxel is an approved drug for systemic chemotherapy for several cancers, and also has well-documented intraperitoneal use for ovarian cancer and gastric cancer. It is a hydrophobic, high molecular weight compound resulting in low absorption through the lymphatic system after IP administration with a much higher peritoneal to plasma peak concentration and AUC ratios (>1000 versus 25 and >1000 versus 16 respectively). As such, IP Paclitaxel may be potentially more efficacious with less systemic toxicity than IP Oxaliplatin. However, no clinical data exists in the published literature for PIPAC/ePIPAC paclitaxel.
This proposed prospective study is the first clinical study of PIPAC/ePIPAC with Paclitaxel. It will determine the maximal tolerated dose (MTD) and evaluate the safety and tolerability, and pharmacokinetics of PIPAC/ePIPAC paclitaxel in pre-treated patients with PC. Peritoneal biopsies will be collected prior to and after PIPAC/ePIPAC to assess tissue drug concentration and depth of drug penetration. Collection of biospecimens including peritoneal tissue, peritoneal fluid and blood will be used for correlative studies including paclitaxel resistance analysis and development of cancer modelling platforms. For the individual patient, repeated biopsies and molecular profiling may also facilitate individualized therapy. For medical research, PIPAC/ePIPAC may deliver measurable progress in 3-5 years because the assessment interval is short (6 weeks) in this disease with rapid progression (6-12 months to death).
This study will determine the safety dose range of PIPAC/ePIPAC paclitaxel. This will allow us to design a phase II trial to evaluate clinical efficacy. On a larger scale, the success of this PIPAC/ePIPAC trial would add a valuable treatment option to our arsenal in the treatment of PC.

PaclitaxelDrug
This is a prospective, two armed phase I trial in a 3 + 3 dose escalation evaluating the safety and tolerability of PIPAC/ePIPAC using paclitaxel in patients with peritoneal carcinomatosis.
| Study group | Role | What they receive |
|---|---|---|
| PIPAC Paclitaxel | Experimental | 3 patients will be allocated to PIPAC arm at Paclitaxel 15mg/m2. If there is 1 dose limiting toxicity (DLT), an additional 3 patients will be allocated to PIPAC arm at 15mg/m2. If there is 2 - 3 DLT, study had exceeded its Maximum Tolerable Dose (MTD) and we will proceed to stop recruitment.
Should there be no DLT, recruitment at PIPAC 30mg/m2 and ePIPAC 15mg/m2 will occurs concurrently in an alternating fashion. PIPAC/ePIPAC dose escalation will continue until a MTD has been reached. Should there be no DLT at PIPAC 30mg/m2 and ePIPAC 15mg/m2, recruitment at PIPAC 45mg/m2 and ePIPAC 30mg/m2 will occurs concurrently in an alternating fashion. Finally, should there be no DLT, recruitment at ePIPAC 45mg/m2 will occurs. Receives: Drug: Paclitaxel |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Paclitaxel in people with Peritoneal Carcinomatosis, run by National University Hospital, Singapore at 1 site in Singapore.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 29 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Bok Yan Jimmy So, MBChB (+65 6772 5555, sursbyj@nus.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tolerability of PIPAC /ePIPAC with Paclitaxel by monitoring dose limiting toxicities (time frame: 1 - 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05395910, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2024.
