About this study

Official title: NeoLIPA: a Single Center Phase II Open Label Study of Neoadjuvant LTX-315 in Combination with Pembrolizumab in Patients with Clinically Detectable and Resectable Stage III-IV Melanoma

This clinical trial aims to evaluate the effectiveness of a new treatment approach for patients with stage III or IV melanoma that has spread to other parts of the body but can still be surgically removed. The study combines two treatments: LTX-315 and pembrolizumab.

Melanoma that has spread to other parts of the body can often be treated with surgery. Despite surgery, there is a high risk of the cancer coming back. Pembrolizumab, an immune checkpoint inhibitor, can reduce this risk when given after surgery. Recent studies have shown that giving pembrolizumab before surgery, along with post-surgery treatment, might be more effective than giving it only after surgery. However, many patients still experience cancer recurrence. Combining pembrolizumab with LTX-315, which triggers a different immune response, might improve the treatment\'s effectiveness and reduce the risk of cancer progression before surgery.

This is an open-label Phase II study, meaning both the researchers and participants will know which treatments are being given. The study will be conducted at a single center and will involve about 27 participants. They will receive LTX-315 and pembrolizumab before their planned surgery to see if this combination could be more effective than pembrolizumab alone.

The primary goal is to assess the tumors response to the neoadjuvant (pre-surgery) treatment, specifically looking at the rate of pathological complete response (pCR), where no cancer is detected in the removed tumor tissue.

Read the detailed description

This is a single arm, single center, open-label phase II study to assess the effect of neoadjuvant LTX-315 in combination with pembrolizumab in patients with clinically detectable and resectable stage III-IV melanoma.

Clinically detectable, fully resectable stage III or oligometastatic IV melanoma can be cured with surgery but has a very high risk of local or systemic recurrence. The risk of recurrence can be significantly reduced by adjuvant treatment with a PD-1 inhibitor. Due to the mode of action of PD-1 inhibitors (stimulating tumor reactive T cells), there is reason to believe that their effect is enhanced if given before definitive surgery and removal of tumor reactive T cells in the tumor microenvironment. Indeed, it was recently shown that the effect is greatly improved if three doses of pembrolizumab are administered prior to surgery (neoadjuvant), followed by 15 doses in the adjuvant setting, compared to giving 18 doses adjuvant.

Several studies have shown that pathologic complete response (pCR) after neoadjuvant treatment correlates with recurrence-free survival (RFS). The pCR rate neoadjuvant pembrolizumab is only modest (20%), and for 8% of the patients, disease progression in the neoadjuvant phase precludes the planned surgery.

LTX-315 is an oncolytic peptide generated from a host defense peptide and has both a direct killing activity and immunomodulatory properties. By inducing cell lysis and immunogenic cell death, LTX-315 can lead to increased T-cell infiltration, broadened repertoire of tumor antigens and increased diversity of T-cell clones, and thus has the potential to enhance the effect of pembrolizumab. Furthermore, the addition of LTX-315 to neoadjuvant pembrolizumab can lower risk of disease progression precluding surgery.

    Rate of Major Pathologic Response (MPR) defined as complete or near-complete (less than 10% of viable tumor in the treated tumor bed) pathologic response

    Measured: After 12 weeks of treatment

  4. Event free survival (EFS)

    Defined as time from start of treatment to progression of disease that precludes surgery, recurrence (local or distant) or death

    Measured: From first dose of treatment to two years

  5. Recurrence free survival (RFS)

    Defined as the time from surgery to recurrence or death.

    Measured: Two years after surgery

  6. Overall Survival (OS)

    Overall Survival

    Measured: Three years after surgery

  7. Quality of Life (QoL)

    Patient reported outcomes (PRO)

    Measured: From first dose to end of treatment at approximately 1.5 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LTX-315 + pembrolizumab in people with Melanoma Stage IIIB-IV, run by Oslo University Hospital at 1 site in Norway.

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 14 inclusion and 15 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: looking for participants now, as of the sponsor's last update on 26 Oct 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 Norway. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Henrik Jespersen, MD PhD (0047 22187285, hejes@ous-hf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete Pathologic Response Rate (time frame: 12 weeks after start of treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 26 Oct 2024.
