About this study

Official title: An Open Label, Non-randomized, First-in-human, Multi-centre Phase I Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Locally Administered DT01 in Combination With Radiotherapy and Concomitant Dose of Chloroquine in Patients With Local Metastatic Melanoma With Relapsed Cutaneous/Subcutaneous Tumors Including Melanoma-in-transit

Phase I trial will be conducted in patients suffering local metastatic melanoma with relapsed cutaneous/subcutaneous tumors including melanoma-in-transit. Based on the preclinical data package, DNA Therapeutics has considered that the risk-benefit ratio of DT01 supports the initiation of a phase I clinical study in this population. The recommended starting dose of DT01 for the first injection to human was based on NOAELs and Maximum Recommended Starting Dose (MRSD) calculations and by considering both local and systemic approaches. It was set at 16 mg (4 mg per injection site, 2 injections per tumor, 2 tumors to be treated). This starting dose will be increased up to 96 mg if no DLT occurred during dose escalation.

DT01 will be locally administered by peritumoral subcutaneous and/or intratumoral injections in combination with hypo-fractionated radiotherapy (RT) (10x 3 Gy) and chloroquine (100 mg oral QD) starting one week before DT01 and RT treatments. DT01 will be administered 3 times a week during two weeks; The study will be an open, non-randomised, multicentre, phase I dose escalation (16, 32, 48, 64 and 96 mg) safety study with a 3+3 design.

The purpose of this study will be to evaluate the safety, tolerance, pharmacokinetics of DT01 in association with palliative radiotherapy and to evaluate pharmacodynamics and the anti-tumor activity of DT01 according to RECIST criteria on day 26, 40 and 54. The duration of response (Time-To-Local Recurrence, TTLR), will be monitored 3, 6, 9 and 12 months after the beginning of the DT01 treatment.

Read the detailed description

According to the WHO, the incidence of melanoma is 199,627 worldwide in 2008, of which the melanoma-in-transit is about 4%. When melanoma spreads, it does so by the lymphatic system which drains to the regional lymph nodes. Uncommonly, melanoma can become trapped in the lymphatic vessels and grow to cause tumor nodules in the skin and subcutaneous tissues between the primary site and the regional lymph node basin. These nodules are termed in-transit metastases and carry an ominous prognosis. The American Joint Committee on Cancer (AJCC) defines such in-transit metastases as any skin or subcutaneous metastases that are more than 2 cm from the primary lesion but are not beyond the regional nodal basin. The 2010 tumor node metastasis (TNM) staging system considers the melanoma-in-transit a N2c stage when they arise in the absence of nodal metastases.

The current treatment options (approved or in late stage development) are:

  • Local excision, if there are only a few;
  • Isolated limb perfusion (local high dose chemotherapy);
  • Systemic chemotherapy (Dacarbazine, Temozolomide, Cis-platine);
  • Targeted therapy (B-raf inhibitors: Vemurafenib and Dabrafenib; MEK inhibitor: Trametinib);
  • Immunotherapy (Ipilimumab, Nivolumab, Pembrolizumab, OncoVEX GM-CSF, Tumor Infiltrating Lymphocytes and interleukin-2 [IL-2]);
  • Radiotherapy;
  • Photodynamic therapy;
  • Laser vaporization. With rare exceptions, none of these treatments are curative. Immunotherapy results in prolongation of survival although overall response rate remains low (ref: oncovex phase II study).

According to the Sponsor's clinical development strategy and plan, the local metastatic melanoma with relapsed cutaneous/subcutaneous tumors, including melanoma-in-transit, has been chosen as the 1st indication for evaluating safety, tolerance and PK of DT01 in combination with a palliative radiotherapy (10x3 Gy). The presence of multiple cutaneous/subcutaneous tumor should provide an initial clinical evaluation of the safety and skin tolerance of the combined treatment of DT01 and 10x3 Gy irradiation, as well as a preliminary assessment of anti-tumor activity (proof of concept) of DT01 to sensitize and improve the response rate of radiotherapy (estimated about 50% response rate), and to delay local relapse.

Based on the pharmacologically active dose in human melanoma xenografted tumor in mice and the wide safety margin estimated from the toxicology data, the starting dose of 16 mg and the planned dose escalation represent a conservative approach for titration. The dose escalation will provide valuable information about the safety, tolerance and preliminary efficacy data.

What participants receive

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

  • DT01Drug

    DT01 starting dose will be 16 mg and it is planned to be increased to 32, 48 mg and 64 mg, or higher.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DT01 in people with Local Metastatic Melanoma, run by DNA Therapeutics at 12 sites in France.

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 9 inclusion and 20 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: finished, as of the sponsor's last update on 17 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in France. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Tolerability and safety analysis, according to the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4 (NCI-CTCAE v4.0) criteria. (time frame: over a period of 54 days). 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 17 Jun 2016.
