About this study

Official title: A Multicenter Phase II Trial of Intratumoral IL12 Plasmid Electroporation in Cutaneous Lymphoma

A single arm, open label, multi-center, phase 2 study to assess the safety and anti-tumor activity of ImmunoPulse IL-12® in participants with stage IB to IIIB mycosis fungoides. ImmunPulseIL12® is the combination of intrtumoral interleukin-12 gene (also known as tavokinogene telseplasmid [tavo]) and in vivo electroporation-mediated plasmid deoxyribonucleic acid [DNA] vaccine therapy (tavo-EP) administered using the OncoSec Medical System (OMS).

All participants may receive up to four cycles of treatment consisting of three treatment days, Days 1, 5 and 8, in a 12-week cycle as per Protocol version 6 (see Limitations and Caveats section of this record for protocol version information). Patients will receive intra-tumoral injection of tavo at a concentration of 1.0 mg/mL (maximum volume of 1 mL/day distributed over 2-4 lesions), followed immediately by electrical discharge around the tumor site resulting in electroporation of plasmid deoxyribonucleic acid (DNA) into tumor cells.

Read the detailed description

This is a single arm, open label, multi-center phase 2 study to assess the safety and anti-tumor activity of intratumoral tavo electroporation in participants with stage IB to IIIB mycosis fungoides. All participants received up to four cycles of treatment consisting of three treatment days, Days 1, 5 and 8, in a 12-week cycle. Patients will receive intra-tumoral injection of tavo at a concentration of 1.0 mg/mL (maximum volume of 1 mL/day distributed over 2-4 lesions), followed immediately by electrical discharge around the tumor site resulting in electroporation of plasmid deoxyribonucleic acid (DNA) into tumor cells. Prior to the first cycle of treatment, the investigator will select at least one lesion, or affected area in erythrodermic patients, to be left untreated for the duration of the study to allow for clinical observation of an untreated site. Participants will be followed for safety and clinical evaluation every 4 weeks. Quality of Life will be assessed using the Skindex29, Functional Assessment of Cancer Therapy - General (FACT-G) and Visual Analog Scale for Pruritus (VAS-P) instruments. Survival follow up will occur at 3-month intervals over 2 years following end of study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tavokinogene Telseplasmid (tavo)Biological

    Also called interleukin-12 gene, IL-12 gene, pIL-12, plasmid DNA encoding human interleukin-12

    Patients received intratumoral injection(s) of tavo.

  • OncoSec Medical System (OMS)Device

    Also called MedPulser

    Electroporation via OMS was performed immediately following intratumoral injection of tavo. A sterile applicator containing 6 stainless steel electrodes arranged in a circle were placed around the tumor. The applicator was connected to the OMS power supply and six pulseswere administered to each tumor lesion at the approximate point of tavo injection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate Assessed by Modified Severity Weighted Assessment Tool (mSWAT) Score in the Skin

    ORR is defined as the percentage of participants that achieved a complete response (CR) or partial response (PR) as assessed by mSWAT score. The mSWAT defines 3 lesion types and assigns each a weighing factor: patch (no induration or significant elevation)=1; plaque (induration, crusting, ulceration or poikiloderma)=2; tumor (solid or nodular ≥ 1 cm in diameter with evidence of deep infiltration and/or vertical growth)=4. Lesions are assessed by body surface area (BSA) where palm + fingers = approximately 1% BSA in each of 12 areas (head, neck, anterior trunk, arms, forearms, hands, posterior trunk, buttocks, thighs, legs, feet, groin), and the sum of each area of BSA is multiplied by its weighing factor. An overall sum of each subtotal represents the mSWAT score (0=no lesions; 400=lesions covering all areas). CR=100% clearance of skin lesions; PR= 50%-99% clearance of skin disease from baseline without new tumors ( ≥1.0 cm in diameter) in patients with T1, T2 or T4 only skin disease.

    Measured: Every 28 days for the first 24-weeks of treatment

  2. Objective Response Rate Assessed by Modified Severity Weighted Assessment Tool (mSWAT) Composite Global Score

    ORR is defined as the percentage of participants that achieved a complete response (CR) or partial response (PR) as assessed by mSWAT Composite Global Score. This assessment evaluated skin, lymph node, blood and visceral involvement. The response generated in each category was used to determine the Global ORR: CR=complete disappearance of all clinical evidence of disease or, no involvement of disease at baseline through time of response evaluation (NI); PR=regression of measurable disease as follows: 100% clearance of skin lesions, all other categories do not have CR/NI and no category has progressive disease (PD) -OR- 50%-99% clearance of skin disease from baseline without new tumors ( ≥1.0 cm in diameter) in patients with T1, T2 or T4 only skin disease, and if any other category was involved at baseline, at least one has CR/PR and no category has PD.

    Measured: Every 28 days for the first 24-weeks of treatment

Secondary outcomes (4)
  1. Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, medical treatment or procedure and which did not necessarily have to have had a causal relationship with this treatment. An adverse event could have, therefore, been any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, medical treatment or procedure whether or not considered related to the medicinal product. An SAE was defined an any untoward medical occurrence that at any dosage resulted in one or more of the following: death, A life-threatening adverse event (real risk of dying), inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly, required intervention to prevent permanent impairment of damage.

    Measured: From the start of study treatment up to 340 days

  2. Duration of Overall Objective Response Assessed by mSWAT Skin Score

    Duration of overall objective response (CR or PR) is defined as the number of days from the initial documentation of an objective response to the most current evaluation of that response or to documentation of progression assessed by mSWAT Skin Score: CR=100% clearance of skin lesions; PR= 50%-99% clearance of skin disease from baseline without new tumors ( ≥1.0 cm in diameter) in patients with T1, T2 or T4 only skin disease.

    Measured: From first documented response until disease progression (Up to 340 days)

  3. Time to Overall Objective Response Assessed by mSWAT Skin Score

    Time to overall objective response (CR or PR) is the number of days from the start of therapy to the first documentation of objective response assessed by mSWAT Skin Score: CR=100% clearance of skin lesions; PR= 50%-99% clearance of skin disease from baseline without new tumors ( ≥1.0 cm in diameter) in patients with T1, T2 or T4 only skin disease.

    Measured: From start of study treatment until overall objective response (Up to 340 days)

  4. Quality of Life (QoL)

    Participants were to complete the following QoL assessments prior to clinical evaluations every 4 weeks: Skindex29, FACT-G (Functional Assessment of Cancer Therapy -General) and VAS-P (Visual Analog for Pruritus) questionnaires.

    Measured: Every 28 days for up to 340 days

A Phase 2 study testing Tavokinogene Telseplasmid (tavo) and OncoSec Medical System (OMS) in people with Cutaneous T Cell Lymphomas (CTCL) and Mycosis Fungoides (MF), run by OncoSec Medical Incorporated 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 25 inclusion and 13 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 15 May 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 3 Jan 2018). 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?

Objective Response Rate Assessed by Modified Severity Weighted Assessment Tool (mSWAT) Score in the Skin (time frame: Every 28 days for the first 24-weeks of treatment). 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 15 May 2023.
