IL13-PE38QQR

targeted fusion protein therapy

Jon Weingart, MD

IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13 receptor-positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells.

IL13-PE38QQR will be infused in two courses of 96 hours each, eight weeks apart, directly into the malignant brain tumors of patients to determine the dose of drug these patients can tolerate. After that, the selected dose will be studied to give an estimate of the response rate, response duration, time to response, and survival after infusing that dose of IL13-PE38QQR into the recurrent malignant glioma.

OBJECTIVES:

I. Determine the toxicities and maximum tolerated dose of IL13-PE38QQR delivered by continuous infusion into malignant glioma over 96 hours, in two courses eight weeks apart.

II. Estimate the response rate, response duration, time to response, and survival after interstitial infusion of IL13-PE38QQR into recurrent malignant glioma.

III. Describe the toxicities of interstitial infusion of IL13-PE38QQR at the selected dose.

PROTOCOL OUTLINE: Patients are expected to receive two IL13-PE38QQR infusions at 8-week intervals. For each course, drug will be infused through each of two catheters; infusion rate will be held constant during a 96-hour infusion.

In Phase I, the dose of IL13-PE38QQR will be increased by increasing the IL13-PE38QQR concentration in stepwise fashion, while holding infusion volume and duration constant. Three patients will be treated at each dose level until the maximum tolerated dose (MTD) is reached, and an additional three patients are treated at that level. In Phase II, patients will be treated at the selected MTD.

PROJECTED ACCRUAL: In Phase I, up to 30 patients will be treated. In Phase II, up to 35 patients will be treated.

This investigator initiated study with a medical device aims to assess the safety and feasibility of percutaneous injected holmium-166 microsphere brachytherapy in patients with irresectable pancreatic cancer.

Objective: To test the feasibility and safety of minimally invasive CT-guided percutaneous holmium-166 microsphere brachytherapy in patients suffering from irresectable pancreatic cancer. Study design: This is a single centre, prospective, safety and feasibility study with a medical device in a maximum of 6 patients.

Study population: Patients diagnosed with pathologically proven pancreatic adenocarcinoma, who are ineligible for exploratory surgery or surgical resection of the tumour after 8 cycles of systemic therapy or less in case of unacceptable toxicity, patient refusal or patients who are ineligible for systematic therapy.

Intervention (if applicable): A radioactive medical device will be implanted by CT-guided percutaneous injection. The medical device in question are beta-minus (β-) and gamma(γ) emitting holmium-166 poly(L-lactic acid) microspheres (166Ho-PLLA-MS, HoMS) in a 0.1% Pluronic or cellulose based suspension.

Main study parameters/endpoints: The main endpoint is to establish the feasibility and safety of CT-guided percutaneous intratumoural implantation of HoMS in irresectable pancreatic adenocarcinoma. Feasibility is established by evaluating the average tumour absorbed dose in Gray (Gy) calculated on SPECT and comparing to the pre-operative planning. Intratumoural microsphere distribution, absorbed tumour dose and non-target absorbed tumour dose are analysed using MRI and CT quantification. Safety is evaluated using the Common Terminology Criteria for Adverse Events (CTCAE v5.0), events deemed 'unlikely', 'probably' or 'definitely' related to the implantation procedure or implanted medical device. As exploratory endpoints, tumour response (RECIST1.1), pain (NRS) and Quality of Life is evaluated. Total follow-up is 16 weeks.

IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13 receptor-positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells.

Patients will receive IL13-PE38QQR via a catheter placed directly into the brain tumor. Tumor recurrence will be confirmed by biopsy. The next day, patients will start a continuous 48-hour infusion of IL13-PE38QQR into the tumor. The dose (concentration) will be increased in the pre-resection infusion until the endpoint is reached (histologic evidence of tumor cytotoxicity or a maximum tolerated dose). Tumor resection will be planned for one week after biopsy, plus or minus 1 day. A histologically-effective concentration (HEC) will be determined using pathologic observations. At the end of resection, three catheters will be placed in brain tissue next to the resection site and assessed within 24 hours using MRI. On the second day after surgery, IL13-PE38QQR infusion will begin and will continue for 4 days. The lowest pre-resection IL13-PE38QQR concentration will be used as the starting dose for post-resection infusions. After an HEC or maximum tolerated dose (MTD) is determined, the pre-resection infusion will no longer be administered. Subsequent patients will have tumor resection and placement of three peri-tumoral catheters at study entry. IL13-PE38QQR will be infused starting on the second day after surgery and continuing for 4 days. Escalation of the post-resection IL13-PE38QQR concentration will be continued until the previously-defined HEC or MTD is reached, after which duration of the post-resection infusion will be increased in one day increments for up to 6 days. If a post-resection MTD is obtained, there will be no increase in duration of infusion. In the final stage of the study, catheters will be placed 2 days after tumor resection, and a 4-day IL13-PE38QQR infusion will begin the day after catheter placement. Patients will be observed clinically and radiographically for toxicity and duration of tumor control.

OBJECTIVES:

I. Determine the concentration of IL13-PE38QQR that produces histologic evidence of toxicity to tumor, and the corresponding drug toxicity, following a 2-day continuous infusion into recurrent malignant glioma prior to surgical resection.

II. Determine the toxicity of IL13-PE38QQR administered as a 4-day continuous infusion via catheters into brain adjacent to tumor resection site, after surgical resection, at concentrations up to the selected concentration.

III. Determine the toxicity of increasing duration of continuous infusion of IL13- PE38QQR via catheters into brain adjacent to tumor resection site, after surgical resection, at the selected concentration.

IV. Determine the feasibility and safety of IL13-PE38QQR administration following post-operative placement of stereotaxic catheters 2 days after tumor resection, utilizing a post-operative imaging study for planning of catheter placement. A 4-day continuous infusion at the MTD is planned.

V. Describe the time to progression and survival of patients treated with IL13-PE38QQR.

PROTOCOL OUTLINE: This study is designed to determine two dose levels. The first is defined as the histologically effective concentration (HEC) when the agent is administered prior to tumor resection. The second is defined using safety and tolerability of study drug administered after tumor resection at doses up to the HEC. Safety and tolerability of increasing duration of infusion after tumor resection will then be assessed.

Patient cohorts will be treated at escalating pre-resection dose-levels until a stopping criterion for the pre-surgery dose is met, holding the post-resection dose constant at the starting level. Stopping criteria for dose escalation of the pre-surgery infusion are determination of the HEC or the maximum tolerated dose (MTD).

Subsequent cohorts will be treated only post-operatively at escalating dose levels until a stopping criterion for the post-surgery dose is met. Stopping criteria for dose escalation of the post-surgery infusion are reaching the HEC determined for the pre-operative infusion or determination of the MTD. After the HEC is reached, subsequent cohorts will be treated with post-operative infusions of increasing duration at the HEC until the maximum duration defined in the study is reached or an MTD is defined. (If an MTD has already detected, duration will not be escalated.)

After the stage of the study evaluating escalation of infusion duration has completed, the study will expand to evaluate post-operative placement of catheters after tumor resection. This stage of the study will assess the feasibility and safety of stereotaxic placement of catheters 2 days after tumor resection using a post-operative imaging study for planning. Patients will receive a 96 hour post-resection infusion at the MTD.

Cohorts of at least three patients will be entered at each dose level. Each cohort will be observed for at least thirty days after completion of administration of study drug to allow for observation of toxicity before the next cohort is enrolled.

PROJECTED ACCRUAL: Depends on number of dose-levels, estimated at 25-50 patients.
