What is an immuno-therapy?
Immuno-therapies are a relatively recent development that are sometimes used in the treatment of cancer. They may work by attacking the cancer cells directly, or by activating a patient’s own immune system to mount an effective attack against the cancer.
WHAT ARE TUMOR INFILTRATING LYMPHOCYTES AND HOW DO THEY WORK?
The TUMOR INFILTRATING LYMPHOCYTE (TIL) therapies being studied in this trial are investigational immunotherapies named LN-144/LN-145.
TIL are derived from a patient’s own immune cells called lymphocytes, and specifically T lymphocytes that can recognize and potentially kill the patient’s own cancer cells. Some of these cells naturally travel to, and penetrate existing cancerous tumors, and are then referred to as TUMOR INFILTRATING LYMPHOCYTES (TIL). However, for various reasons the immune-suppressive environment of the cancerous tumors limits their number and activity which diminishes their ability to effectively attack the cancer.
The TIL therapy under investigation in this clinical trial, LN-144/LN-145, are derived through isolation of a patient’s own naturally occurring TIL from a sample of cancerous tumor removed from the patient. After TIL are extracted from the tumor, they are multiplied in a laboratory until billions of TIL are obtained. Prior to receipt of TIL, patients receive a pre-conditioning therapy to reduce the immune suppressive environment of cancer that remains in the patient. The expanded TIL are then administered via intravenous infusion back to the patient as LN-144/LN-145 (TIL therapy), with the intention that the TIL will target and infiltrate cancer in the patient and attack the cancer in greater number. Patients receive up to 6 doses of interleukin 2 (IL-2) immediately following TIL infusion to support growth and activation of the TIL in the patient, and to augment the anti-cancer activity of the TIL therapy.
OVERVIEW OF TIL THERAPY PROCEDURE
- Tumor is surgically isolated from patient.
- Tumor sample is shipped to the GMP facility where TIL are isolated and multiplied to generate billions of TIL over three weeks.
- Patient initiates a week of pre-conditioning therapy to prepare to receive TIL.
- TIL product is administered as a one-time therapy followed by up to 6 doses of IL-2 to support growth and activation of the TIL therapy inside the patient.
WHAT CLINICAL RESULTS HAVE BEEN OBSERVED WITH TIL THERAPIES AS A CANCER TREATMENT?
TIL therapy is based on an adoptive cell therapy regimen that was developed at the National Cancer Institute (NCI) and which is currently being applied at a small selection of leading cancer centers around the world. So far, most of the data on TIL therapy has been obtained from studies in metastatic melanoma, a form of aggressive skin cancer, as well as cervical cancer.
Recent data from two trials at the NCI in patients with metastatic melanoma confirmed TIL treatment was associated with high, durable objective responses. In a 93 patient Phase 2 trial, the objective response rate (ORR) was 56%.1 Another trial of 101 patients observed complete responses (CR, total elimination of detectable tumors) in 24% of patients, some of whom were free of disease for more than four years. 2
Three clinical trials have presented data showing that patient survival is associated with tumors containing higher amount of TIL.3-5 In addition to melanoma, head and neck and NSCLC are indications in which TIL is expected to work. Furthermore, Iovance has generated preliminary clinical data showing activity of TIL in head and neck indication.6 Early data from a research study at H. Lee Moffitt Cancer center has shown activity of TIL for NSCLC patients who have failed to see a benefit from their prior anti-PD-1 therapy as well.7
CLINICAL TRIAL OVERVIEW
IOV-COM-202 is a Phase 2 clinical trial, enrolling patients that have been diagnosed with histologically confirmed unresectable or metastatic melanoma (Cohort 1), recurrent or metastatic squamous cell carcinoma of the head and neck (Cohort 2), or recurrent or metastatic non-small cell lung cancer (Cohort 3).
Cohort 1 and 2 include patients who have not received prior immunotherapy, including checkpoint inhibitors (e.g., anti-PD-1/anti-PD-L1 and/or anti-CTLA-4). With the excluded prior therapies cited, patients may have received from 1 to 3 prior systemic anticancer therapies, specifically:
- In Cohort 1: Patients with unresectable or metastatic melanoma (Stage IIIC or Stage IV); if BRAF mutation-positive, patients may have received a BRAF inhibitor.
- In Cohort 2: Patients with unresectable or metastatic HNSCC. Those who may have received initial chemo-radiotherapy are allowed.
Cohort 3 patients include Stage III or Stage IV NSCLC (squamous, nonsquamous, adenocarcinoma, or large cell carcinoma) who have received from 1 to 3 prior systemic anticancer therapies, including checkpoint inhibitors (eg, anti-PD-1/anti-PD-L1) in the locally advanced or metastatic setting.
The clinical trial is designed to determine if Iovance investigational TIL therapy (LN-144/LN-145) is safe and effective for the treatment of unresectable/metastatic melanoma, recurrent/metastatic HNSCC, and NSCLC (helps patients live longer and/or slow down cancer progression).
There are several objectives to the trial, some of which aim to determine:
- Whether LN-144/LN-145 alone or in combination with pembrolizumab is safe.
- Whether LN-144/LN-145 in combination with pembrolizumab reduces or slows the progression of metastatic melanoma and HNSCC.
- Whether LN-144/LN-145 in combination with pembrolizumab eliminates all detectable metastatic melanoma and HNSCC.
- Whether LN-145 reduces or slows the progression of NSCLC.
- Whether LN-145 eliminates all detectable NSCLC.
- Whether treatment with LN-144/LN-145 alone or in combination with pembrolizumab extends the life of a patient without their cancer worsening
LN-144/LN-145 are investigational therapies that are being tested in clinical studies and has not been approved by the FDA or any other agency for any indication. A clinical trial is designed to explore efficacy and safety of experimental therapies. You should talk to your doctor about the benefits and risks of participating in this trial.
YOU MAY QUALIFY FOR THE TRIAL IF:
- You have been diagnosed histologically with:
- unresectable or metastatic melanoma (checkpoint naïve, up to 3 prior therapies)
- recurrent or metastatic HNSCC (checkpoint naïve, up to 3 prior therapies)
- locally advanced or metastatic NSCLC (1 to 3 prior therapies with checkpoint inhibitors)
- You are at least 18 years old
If you satisfy these key eligibility criteria, you may be eligible to participate in this clinical trial. There are other additional eligibility criteria that can only be assessed by a trial physician.
