Plain-language summary
This is a first-in-human (FIH), Phase 1/2, open-label, multicenter study to assess safety and determine the recommended Phase 2 dose (RP2D) of BOXR1030 administration after lymphodepleting chemotherapy (LD chemotherapy) in subjects with glypican-3 positive (GPC3+) advanced solid tumors.

Inclusion criteria
. Aged 18 to 80 years at time of enrollment
. Body weight \>/= 50kg
. Able to provide a recent tumor specimen taken within 6 months prior to signing consent and after the initiation of the subject's most recent systemic anti-cancer therapy, for GPC3 expression assessment by immunohistochemistry (IHC). Previously collected tumor tissue older than 6 months at time of GPC3 IHC testing or collected prior to initiation of current or last systemic therapy may be permitted for GPC3 prescreening. If prescreening sample is found to be GPC3+, a new tumor biopsy will be needed to confirm tumor remains GPC3+ in order to proceed.
. Histologically confirmed advanced unresectable or metastatic hepatocellular carcinoma (HCC), squamous cell carcinoma (SCC) of the lung, myxoid/round cell liposarcoma (MRCLS), or Merkel cell carcinoma (MCC) with GPC3 overexpression by IHC. Subjects must consent to IHC testing in a separate informed consent. Note: Tumor samples will be sent to a central laboratory for GPC3 expression analysis.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Dose limiting toxicity
Timeframe: From the time of BOXR1030 administration (Study Day 1) through 28 days after BOXR1030 administration (Study Day 28/Week 4)
2
MTD
Timeframe: From the time of BOXR1030 administration (Study Day 1) through 28 days after BOXR1030 administration (Study Day 28/Week 4)
3
RP2D
Timeframe: From the time of BOXR1030 administration (Study Day 1) through 28 days after BOXR1030 administration (Study Day 28/Week 4)
4
Treatment-emergent AEs (TEAEs)
Timeframe: From the time of BOXR1030 administration (Study Day 1) through Week 24
. Documentation of disease progression or refractory disease or intolerance to prior lines of standard-of-care therapies. Patients with tumors with genetic alterations and mutations (e.g., breast cancer gene, epidermal growth factor receptor mutations, and anaplastic lymphoma kinase translocation) who have approved targeted therapies available for their cancer will need to have been treated with such approved therapies or refused such approved targeted therapy for their cancer prior to enrolling in this study.
. Life expectancy \>16 weeks
. Have adequate organ function (renal/hepatic/pulmonary)
. Left ventricular ejection fraction ≥50% by multiple-gated acquisition scan or echocardiogram
Exclusion criteria
. Prior treatment with adoptive cell therapy (e.g., CAR T-cell therapy, natural killer cell therapy, engineered T-cell receptor therapy).
. History of allogenic hematopoietic stem cell transplant.
. Known untreated CNS tumors or brain metastasis. Subjects are eligible if CNS metastases are asymptomatic, have been treated with radiotherapy for at least 1 month prior to informed consent, are off corticosteroids and have neurologically returned to baseline (residual signs or symptoms related to the CNS treatment are permitted). Imaging obtained for the purpose of CNS metastases management performed during screening must document radiographic stability of CNS lesions for at least 1 month prior to leukapheresis and be performed after completion of any CNS directed therapy. If brain scans are performed, magnetic resonance scans are preferred; however, computed tomography scans are acceptable if magnetic resonance imaging is medically contraindicated. CNS evaluation for subjects with no suspicion of brain tumors in their history is not required for the study. Subjects with known leptomeningeal metastases are excluded.
. Subjects who have not recovered to \< 1 or baseline from all AEs due to previous therapies (subjects with ≤ grade 2 peripheral neuropathy that has been stable for at least 4 weeks or \< grade 2 endocrine-related AEs that has been stable for at least 4 weeks on replacement therapy).
. Planned use of any antineoplastic treatment or investigational agent from the time of the first dose of LD chemotherapy through the end of study participation, except for allowed local radiation of lesions for palliation (to be considered non-target lesions after treatment) and hormone ablation.
. Uncontrolled or life-threatening symptomatic concomitant disease including clinically significant gastrointestinal bleeding or pulmonary hemorrhage within 4 weeks before screening, known symptomatic human immunodeficiency virus (HIV) positive with an acquired immunodeficiency syndrome-defining opportunistic infection within the past 12 months prior to screening, or a current CD4 count \<350 cells/µL, symptomatic active hepatitis B or C checked at screening, or active tuberculosis therapy.
. Has received prior radiotherapy within 2 weeks of the start of BOXR1030. Subjects must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had severe radiation pneumonitis.
. Potentially life-threatening second malignancy requiring systemic treatment within the last 3 years (i.e., subjects with a history of prior malignancy are eligible if treatment was completed at least 3 years before entering the Treatment Period and the subject has no evidence of disease) or which would impede evaluation of treatment response.
