Treatment Pleural Carcinosis of Pressurized IntraThoracic Hyperthermic Aerosol Cisplatin Administration (PITHAC)

Published: March 1, 2024

Primary Outcome Measures

1. Outcome Measure

Dose Escalation and Maximum Tolerated Dose determination (Part A):

Measure Description

In order to determine the maximum tolerated dose (MTD) of cisplatin administered by PITHAC, the primary study outcome will be the occurrence of Dose Limiting Toxicities (DLT).

Time Frame

18 months approximately

2.  Outcome Measure

Expansion Phase

Measure Description

Safety profile of cisplatin administered by PITHAC will be assessed by the incidence of Adverse Events and Serious Adverse Events according to NCI-CTCAE criteria (v5). Incidence and severity of intraoperative and post-operative complications will be measured using the Clavien-Dindo classification up to 30 days after the intervention.

Safety profile of cisplatin administered by PITHAC will be assessed by the incidence of Adverse Events and Serious Adverse Events according to NCI-CTCAE criteria (v5). Incidence and severity of intraoperative and post-operative complications will be measured using the Clavien-Dindo classification up to 30 days after the intervention.

Time Frame

between 10 and 12 months

Secondary Outcome Measures

Outcome Measure

Dose Escalation and MTD determination (Part A):

Measure Description

Safety profile of cisplatin administered with moderate hyperthermic PITHAC will be assessed by the incidence of Adverse Events and Serious Adverse Events according to NCI-CTCAE criteria (v5).

Dyspnoea will be scored every day until Day 10 and re-evaluated at Day 30 after the procedure

The pleural effusion index will be determined by comparing chest X-rays before, 24 hours (Day 0), at Day 10 and at Day 30 after PITHAC and pleurodesis or indwelling catheter placement

Time Frame

18 Months

Outcome Measure

Expansion phase (Part B):

Measure Description

Dyspnoea will be scored every day until Day 10 and re-evaluated at Day 30 after the procedure.

The pleural effusion index will be determined by comparing chest X-rays before PITHAC procedure, 24 hours after, at Day 10 and Day 30 after PITHAC and pleurodesis or indwelling catheter placement.

Time Frame

10 /12 months

Other Outcome Measures

Outcome Measure

Dose Escalation and MTD determination (Part A):Exploratory outcomes

Measure Description

Tissue immune infiltration will be assessed by comparing penetration depth and resulting immune infiltrate in pleural biopsy specimens at the beginning and at the end of PITHAC.

The correlation between plasma concentrations of administered intrapleural cisplatin by PITHAC and acute secondary side effects will be evaluated.

Tissue distribution of free cisplatin will be compared in pleural biopsy specimens at the beginning and at the end of PITHAC by gaz phase chromatography.

Correlation between treatment outcome, percentage of cancer cell death, cisplatin concentration in pleural biopsies, release of pro-inflammatory proteins and the activation status of effector T-cell will be assessed.

Assess the immune environment and immune responses mediated by neoantigen directed cytotoxic T cells (neoantigen landscape) in patient malignant pleural effusion (MPE) before and after PITHAC ((D0, 72h post intervention, Day 10 and D30).

  • Non-small cell lung cancer, breast cancer, lymphoma, ovarian cancer, oesophageal cancer, gastric cancer, and malignant tumour of the serous membranes (mesothelioma) confirmed by pathology either as part of a diagnostic workup of suspected pleural carcinosis OR available from other previous examinations patients undergoing a planned videothoracoscopy to perform pleurodesis or a placement of a tunnelled catheter
  • Adequate liver, kidney, and bone marrow functions as assessed by laboratory tests (serum total bilirubin <1.5 mg/dl, aspartate transaminase and alanine transaminase less than 2.5 times the upper limit of the normal range, creatinine clearance ≥60 ml/min, absolute neutrophil count ≥1,500/μl, haemoglobin ≥90 g/L, platelets ≥100,000/μl)
  • I) Patients with past/resolved HBV infection (defined as having a negative HBsAg test and a positive antibody to hepatitis B core antigen [anti-HBc] antibody test) are eligible, if HBV DNA test is negative. Ii) HBV DNA must be obtained in patients with positive hepatitis B core antibody prior start of study treatment.
  • Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA
