What is the purpose of this trial?

This trial tests the safety of a new treatment called X-PACT (X-Ray Psoralen Activated Cancer Therapy) for individuals with certain advanced cancers, such as head and neck cancer, breast cancer, soft tissue sarcoma, or melanoma. The treatment involves injecting a combination of a phosphor device and a methoxsalen solution directly into the tumor, followed by exposure to X-ray energy. Ideal participants have specific types of advanced tumors accessible by injection and have not found success with other standard therapies. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the chance to be among the first to receive this innovative therapy.

Do I have to stop taking my current medications for the trial?

The trial requires a one-week period without corticosteroids before starting, and you must not have had systemic anti-cancer treatment within 28 days before the trial. Other medications are not specifically mentioned, so it's best to discuss with the trial team.

What prior data suggests that the X-PACT treatment is safe for advanced cancers?

Research shows that X-PACT, a new cancer treatment, is generally well-tolerated. It uses low doses of X-rays to target tumors, protecting the surrounding healthy tissue. Earlier studies aimed these low-dose X-rays directly at tumors, and the treatment did not cause severe side effects.

However, since this trial is in its early stages, the researchers are still assessing its safety. The aim is to ensure that no more than 2 out of 12 patients experience serious side effects during the initial treatment period. This trial will help confirm if X-PACT is safe for more patients in the future. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for advanced cancers, which often involve chemotherapy or radiation, X-PACT is unique because it combines a phosphor device and a methoxsalen sterile solution with X-ray energy, targeting tumors directly via intra-tumoral injections. This innovative approach allows the treatment to act precisely on cancer cells, potentially reducing harm to surrounding healthy tissues. Researchers are excited about X-PACT because it offers a new mechanism of action that could result in effective tumor control with fewer side effects and an improved quality of life for patients.

What evidence suggests that X-PACT is effective for advanced cancers?

Research suggests that X-PACT therapy, which participants in this trial will receive, might reduce cancer severity. This treatment uses special substances called psoralens, which can fight tumors, and activates them with X-ray energy. In lab studies, X-PACT caused more cancer cell death and damage than using psoralens or X-rays alone. Additionally, X-PACT treatment resulted in lower levels of certain proteins linked to cancer severity. These early findings indicate that X-PACT could effectively combat advanced cancers. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

Adults over 18 with advanced head & neck cancer, breast cancer, soft tissue sarcoma or melanoma can join this trial if their tumor is superficial (less than 5 cm deep), measurable by RECIST criteria, and accessible for injection. They must have an ECOG Performance Status of ≤1, adequate organ function, no severe allergies to psoralen compounds or the phosphor device components, not be pregnant/breastfeeding and agree to use effective contraception.

Inclusion Criteria

Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.

My tumor can be reached for treatment either directly or with imaging guidance.

My side effects from previous treatments are mild or gone.

Exclusion Criteria

I haven't had any cancer treatments in the last 28 days or 5 half-lives, whichever is shorter.

I have a history of pancreatitis or high levels of lipase in my blood without a known cause.

I have another cancer besides the one being studied, but it's either not active or is a minor type that doesn't require treatment.

What Are the Treatments Tested in This Trial?

Interventions

• X-PACT

Trial Overview

The X-PACT treatment involves injecting a combination product into the tumor and exposing it to X-ray energy. This Phase I trial aims to establish safety through five injections over six weeks. Patients showing stable disease or response may receive two additional boosters. Safety will be determined if ≤2 out of 12 patients experience dose-limiting toxicity post-treatment.

How Is the Trial Designed?

Group I: X-PACT Treatment Experimental Treatment 1 Intervention

Single arm consisting of a six-week treatment period with X-PACT (phosphor device and methoxsalen sterile solution and subsequently exposing the tumor to X-ray energy) administered as an intra-tumoral injection. Intra-tumoral injections will be given on D1, D3 and D5 of Week 1, on D1 of Week 2, and a booster on D1 of Week 6. After the week 8 tumor assessment subjects demonstrating stable disease, partial response or unconfirmed progression assessed by iRecist, will be eligible to receive two additional booster treatments 4-6 weeks apart.

Published Research Related to This Trial

The R2Pulm trial found no significant difference in event-free or overall survival between patients with Ewing sarcoma treated with high-dose busulfan-melphalan chemotherapy and those receiving standard chemotherapy with whole-lung irradiation, indicating similar efficacy.

However, the BuMel treatment was associated with higher rates of severe acute toxicities, including four deaths related to treatment, suggesting that the standard VAI plus WLI approach may be safer for patients.

A high tumor engraftment rate of 77.8% was achieved using two methods (subcutaneous and subrenal capsule) to establish patient-derived tumor xenograft (PDTX) models from 18 high-risk endometrial cancer patients, providing a robust platform for drug evaluation.

The study confirmed that the PDTX tumors closely resemble the primary tumors in terms of histology and genetic profiles, making them valuable for personalized medicine strategies and biomarker identification in high-risk endometrial cancers.

The study established five patient-derived xenograft (PDX) models of nasopharyngeal carcinoma (NPC) and identified significant genetic alterations, including cyclin D1 amplification and CDKN2A deletion, which are potential targets for personalized cancer therapy.

Palbociclib, a cyclin-dependent kinase inhibitor, demonstrated anti-tumor effects in NPC PDX models and showed promise in a patient with liver metastasis, leading to stable disease and a reduction in Epstein-Barr virus (EBV) levels.

In a study involving 30 patient-derived xenografts (PDXs) from pediatric tumors, a successful engraftment rate of 44% was observed, with factors like age over 12 years and relapsed disease linked to higher rates of engraftment.

PDX engraftment from newly diagnosed patients was found to be a significant prognostic factor for poor outcomes, particularly in standard-risk Ewing sarcoma, indicating that successful PDX models may predict a higher risk of relapse or refractory disease.

In a study of 107 patients with recurrent Ewing sarcoma, the 5-year post-relapse survival rate was found to be only 19%, highlighting the challenges in treating this aggressive cancer after relapse.

Factors such as being younger than 15 years, having a longer time to recurrence (over 24 months), and recurrence limited to the lungs were associated with better post-relapse survival, while no survival benefit was observed from high-dose chemotherapy consolidation.
