Brief Summary

In this Phase I trial for subjects with advanced head & neck cancer, breast cancer, soft tissue sarcoma or melanoma all subjects will receive open label X-PACT treatment as a intra-tumoral injection. The primary objective will be to establish the safety of X-PACT when dosed with 5 intra-tumoral injections of the combination product (the phosphor device and methoxsalen sterile solution and subsequently exposing the tumor to X-ray energy) over a period of 6 weeks (on day 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. Treatment will be considered safe provided ≤ 2 out of 12 patients experience a dose-limiting toxicity (DLT) during the 6 weeks after the first intra-tumoral injection.

Detailed Description

The primary endpoint will be to establish the safety of X-PACT when dosed with 5 intra-tumoral injections of the combination product (the phosphor device and methoxsalen sterile solution and subsequently exposing the tumor to X-ray energy) over a period of 6 weeks (on day 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. Part C has been added to the study to allow patients who respond to treatment to receive an additional 12 treatments over 12 months. In part C, up to two tumors in up to two radiation fields may be treated. Treatment will be considered safe provided ≤ 2 out of 12 patients experience a dose-limiting toxicity (DLT) during the 6 weeks after the first intra-tumoral injection. Subjects will have staging scans at baseline, day 8, week 7 and as per standard of care during the optional treatment and follow up study periods. There will be a two-year follow up period.

Study Groups

X-PACT Treatment

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.

Group Type: EXPERIMENTAL

X-PACT

Intervention Type: COMBINATION_PRODUCT

X-PACT is comprised of a phosphor device, the drug methoxsalen sterile solution and X-ray energy. The dose of methoxsalen sterile solution per injection will vary per patient and will remained fixed across injections within each patient as it is based on the applicable tumor volume at baseline. Immediately after each injection of the combination product, patients will be exposed to an X-ray beam delivered via a LINAC (and thus targeted at the tumor) at a fixed dose to activate the combination product.

Eligibility Criteria

Inclusion Criteria

1. 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.

2. Age ≥ 18 years at the time of consent

3. ECOG Performance Status of ≤ 1

4. Subjects with histologically or cytologically confirmed advanced solid tumors which have progressed after standard therapy(ies), intolerant to standard therapy, refused standard therapy or for which no standard therapy(ies) exist. Furthermore, the tumor targeted for injections should be:

1. A non-visceral tumor, a metastatic lymph node, a metastasis from a visceral solid tumor provided the lesion is extravisceral, or a cutaneous tumor. Visceral tumors will not be treated.

2. The tumor must be measurable as per RECIST criteria.

3. The tumor should be directly accessible for injection or accessible with the use of ultrasound/CT guidance.

4. The tumor identified for injection should be selected so local control could potentially provide benefit to the patient.

5. 80% of the tumor must be accessible for injection with X-PACT (assessed by the treating physician)

6. The tumor must be superficial and not exceed a depth of 5 cm.

7. Eye or brain tumors will not be treated.

5. A patient with prior brain metastasis may be considered if they have completed their treatment for brain metastasis at least 4 weeks prior to day 1 of treatment, have been off of corticosteroids for ≥ 2 weeks, and brain metastases are asymptomatic.

6. The study site Radiation Oncologist Investigator/sub-investigator has determined additiional radiation delivered via X-PACT is appropriate given patient's prior radiation exposure. The treating Radiation Oncologist will review all prior radiation received to the proposed site of X-PACT treatment and assess the potential for unacceptable toxicity to the site or local organ(s) using QUANTEC.

7. All toxicities from prior therapy should be ≤Grade 1 before start of study treatment. All radiation associated toxicities must have completely resolved to be considered for inclusion into the study.

8. Demonstrate adequate organ function as defined in the table below:

Hematological:

White blood cell (WBC) ≥ 3 x 109/L Absolute Neutrophil Count (ANC) ≥ 1.5 x 109/L Platelet Count ≥ 100 x 109/L Hemoglobin (Hgb) ≥ 8 g/dL2

Renal:

Serum creatinine OR Creatinine clearance ≤ 1.5 x upper limit of normal (ULN) OR, in patients with a serum creatinine 1.5 x ULN, ≥ 60 mL/min as measured by a 24-hour urine collection or estimated by the Cockcroft and Gault formula

Hepatic:

Total bilirubin ≤ 1.5 × ULN (in patients with known Gilbert Syndrome a total bilirubin ≤3.0× ULN with direct bilirubin ≤1.5 X ULN) Aspartate aminotransferase (AST) ≤ 2.5 × ULN (or ≤ 5 if liver metastases are present) Alanine aminotransferase (ALT) ≤ 2.5 × ULN (or ≤ 5 if liver metastases are present)

Coagulation:

International Normalized Ratio (INR) ≤ 1.5

9. Females of childbearing potential (FCBP) must have a negative serum pregnancy test within 3 days prior to day 1 of treatment. NOTE: Females are considered of childbearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are postmenopausal (at least 12 consecutive months with no menses without an alternative medical cause).

10. FCBP must be willing to use a highly effective contraceptive method (i.e., achieves a failure rate of <1% per year when used consistently and correctly) from the time of informed consent until 28 days after treatment discontinuation. Contraceptive methods with low user dependency are preferable but not required (see table below, adapted from:

http://www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf)

Highly Effective Birth Control Methods:

• combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation

• oral
• intravaginal
• transdermal
• progestogen-only hormonal contraception associated with inhibition of ovulation

• oral
• injectable
• implantable
• intrauterine device (IUD)
• intrauterine hormone-releasing system (IUS)
• vasectomised partner
• sexual abstinence

11. Male patients must be willing to use condoms from the time of informed consent until 28 days after treatment discontinuation. For a non-pregnant FCBP partner, contraception recommendations should also be considered.

12. As determined by the enrolling physician, ability of the patient to understand and comply with study procedures for the entire length of the study

13. Patient is expected to have a life expectancy of at least 4 months

14. If the proposed site of treatment with X-PACT had prior exposure to curative-intent radiation, the patient may be entered into the trial with the following provisions satisfied.

• There is at least a 6 month wash out period from the last date radiation was received to assess for radiation toxicity.
• If there was previous radiation toxicity at the proposed site of X-PACT, the toxicity resolved at least three months ago and the site did not involve a major organ.
• The site investigator in addition to the radiation oncologist (as a part of criterion #6) has fully reviewed the subject's radiation history, has examined the area for radiation toxicity and assessed the cumulative dose for either 5 or 7 X-PACT treatments and determined they will not pose additional risk for radiation toxicity or re-activate any other previous toxicity.
