About this study

Official title: Phase 2 Study of OBP-301 (Telomelysin ™) in Combination With Pembrolizumab and Stereotactic Body Irradiation in Patients With Head and Neck Squamous Cell Carcinoma With Inoperable, Recurrent or Progressive Disease

The purpose of this study is to test the effects, of the research study drug Telomelysin (OBP-301) in combination with pembrolizumab in subjects with inoperable, recurrent, or progressive squamous cell carcinoma of the head and neck. Telomelysin is an investigational treatment, while pembrolizumab and SBRT are approved standard treatments. The combination of these three treatments is also considered investigational.

Read the detailed description

This is a phase II open label single arm study of OBP-301 in combination with pembrolizumab and SBRT in advanced HNSCC which is either recurrent and inoperable, or progressing after prior radiation with curative-intent for advanced disease (adjuvant or definitive with or without chemotherapy or cetuximab).

The efficacy of pembrolizumab monotherapy is modest in second or third line of treatment of advanced head and neck cancer (~response rate 16-22%). SBRT reirradiation in patients that received prior surgery and chemoradiation for advanced disease is associated with a response rate (RR) of approximately 60% and approximately 50% 1-year survival. Recently, the results of the Keynote-048 study were published. The projected 1-year survival in the immunotherapy arms with pembrolizumab alone or pembrolizumab and chemotherapy was approximately 57%. So, at present, the benchmark RR for patients with head and neck squamous cell carcinoma with inoperable, recurrent or progressive disease treated with SBRT is approximately 60% and the 1 year survival for patients with head and neck squamous cell carcinoma (HNSCC) with inoperable, recurrent or progressive disease using the most effective contemporary treatments including immunotherapy is approximately 50-57%. Trying to improve the results of the current standard of care, this study will examine the effects of oncolytic virus, OBP-301, administered in addition to pembrolizumab and SBRT in this patient population. The goal of using this triple therapeutic combination is to enhance the chances of cure of the patients.

A total of 36 patients will be enrolled into a two-stage parallel cohort design: In the first stage, 12 patients will be enrolled.

All patients will receive intratumoral injection(s) with OBP-301. If tolerated and no progression is observed, up to twelve injections may be given in each patient.

If the targeted injected lesion(s) disappear, another lesion can be injected at the Investigator's discretion.

A minimum additional 3 doses of concurrent OBP-301 and pembrolizumab will be given if no toxicity, technical impediment to injection or progression is seen.

A maximum total of up to 9 doses of concurrent OBP-301 and pembrolizumab will be given.

Pembrolizumab alone will be continued after day 183 for a total treatment time up to 1 year.

    We will measure the rate of grade 3 or 4 adverse events attributed to the combination of multiple intratumoral injections of OBP-301 with SBRT and pembrolizumab.

    Measured: 30 months

Secondary outcomes (6)

  4. Duration of Response (DoR), as Measured by Subjects Who Have Responded to Combination Therapy Remain Without Disease Progression

    defined as the percentage of patients who have achieved complete response, partial response and stable disease.

    Measured: 30 months

  5. Immune Related Response Rate (irRR), as Assessed by Radiographic Imaging

    Examination of subjects with stable disease, a partial response, or complete response.Immune-related disease progression (irPD) will be confirmed if the increase in tumor burden is ≥ 25% relative to nadir (minimum recorded tumor burden).

    Measured: 30 months

  6. Response in Non-target Lesions, as Assessed by Radiographic Imaging

    Examination of patients with a partial response or complete response based on RECIST 1.1 and iRECIST

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing OBP-301 and Pembrolizumab in people with Head and Neck Squamous Cell Carcinoma With Inoperable Recurrent or Progressive Disease, run by Weill Medical College of Cornell University at 1 site in United States.

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 19 inclusion and 18 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: stopped early, as of the sponsor's last update on 11 Jan 2023. 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 United States. 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?

Yes. Results are posted in the registry (first posted 11 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate, as Assessed by Radiographic Imaging (time frame: 30 months). 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?
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 11 Jan 2023.
