The clinical study will assess the safety and tolerability of escalating intratumoral doses of mRNA-2752 in participants with relapsed/refractory solid tumor malignancies or lymphoma.


This is a Phase 1, open-label, multicenter, dose-escalation study of intratumoral injections of mRNA-2752 alone and in combination with intravenously administered immune checkpoint blockade therapy in participants with histologically confirmed advanced or metastatic solid tumor malignancies or lymphoma. The study consists of Dose Escalation and Dose Confirmation Parts, which will occur in Arm A and Arm B, followed by a Dose Expansion Part, which will occur in Arm B, and a Dose Exploration in Arm C as a neoadjuvant therapy for cutaneous melanoma.

Participants in Arm A and in Arm B will be enrolled into the Dose Escalation Part and the doses of mRNA-2752 will be administered in a dose escalation regimen until a maximum tolerated dose (MTD) or a recommended dose for expansion (RDE) is identified. When the MTD/RDE is identified, participants with solid tumors or lymphoma with visceral lesions may be enrolled into the Dose Confirmation Part to confirm that the dose is also appropriate for this subgroup.

Condition Dose Escalation: Relapsed/Refractory Solid Tumor Malignancies or Lymphoma, Dose Expansion: Triple Negative Breast Cancer, HNSCC, Non-Hodgkins, Urothelial Cancer, Immune Checkpoint Refractory Melanoma, and NSCLC Lymphoma
Treatment durvalumab, mRNA-2752, mRNA-2752 + durvalumab, mRNA-2752 + tremelimumab

Yes No Not Sure

Inclusion Criteria

Written informed consent prior to completing any study-specific procedure
Histologically confirmed advanced or metastatic disease with at least 1 measurable lesion as determined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or Cheson 2016 criteria
Dose Escalation/Confirmation
Has disease progression after adequate standard of care therapies for metastatic disease that are known to confer clinical benefit, is intolerant to treatment, or refuses standard treatment (no limit to prior lines of therapy)
Dose Expansion
Group 1 Triple negative breast cancer: Must have objective evidence of disease progression during or following at least one prior line of therapy for metastatic or locally advanced disease
Group 2 Head and neck squamous cell carcinoma: Must have objective evidence of disease progression during or following platinum-containing chemotherapy as well as a programmed death -ligand 1 (PD-1/L1) therapy
Group 3 Non-Hodgkin's lymphoma: Must have objective evidence of disease progression following an anthracycline containing chemotherapy regimen, as well as an anti-CD20 monoclonal antibody unless CD20 is determined to be negative. Participants with transformed follicular lymphoma must have received prior chemotherapy for follicular lymphoma and subsequently have chemorefractory disease after transformation to diffuse large B-cell lymphoma (DLBCL)
Group 4 Urothelial cancer, first line: Must be cisplatin ineligible and PD-L1 negative
Group 5 Urothelial cancer: Must have objective evidence of disease progression during or following platinum-containing chemotherapy
Group 6 Cutaneous melanoma: Must be refractory to immune checkpoint blockade in the primary or secondary acquired resistance setting
Group 7 Non-small cell lung cancer, primary refractory or secondary acquired resistance to immune checkpoint blockade
Dose Exploration
Has a body weight of >30 kilograms (kg)
Newly diagnosed resectable, BRAF wild-type, Stage IIB-IV cutaneous melanoma in the neoadjuvant setting
Adequate hematological and biological function
Has a tumor lesion amenable to biopsy and must be willing to provide the baseline and
Has evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal participants
on-treatment tumor biopsy samples if medically feasible. For participants with
only 1 lesion amenable to injection, biopsy, and RECIST assessment, that
lesion must be ≥2 centimeters (cm)
Eastern Cooperative Oncology Group (ECOG) performance status of ≤1
Treatment Arm B and Arm C: Clinical euthyroid status defined as thyroid-stimulating hormone or free T3/T4 within normal range

Exclusion Criteria

Has current or prior use of immunosuppressive medication within 14 days before the first dose of study treatment
Active central nervous system tumors or metastases
Has received a live vaccine within 30 days before the first dose of study treatment
Has received prior systemic anti-cancer therapy including investigational agents within 5 half-lives or 28 days of the start of study treatment, whichever is shorter. Participants enrolled to Arm C may not have received any previous anti-cancer therapy, immune therapy, radiotherapy, or investigational agents
Have major surgical procedures within 28 days or non-study-related minor procedures within 7 days before the first dose of study treatment
Requires active systemic anticoagulation at the time of intratumoral injection or biopsy
Has received prior radiotherapy within 14 days before the first dose of study treatment. Participants enrolled to Arm C may not have had prior anticancer therapy including radiotherapy
Active or prior documented autoimmune or inflammatory disorders
History of primary immunodeficiency, allogenic solid organ transplantation, or tuberculosis
Participants with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician
Has active GI bleeding or hemoptysis or history of bleeding disorder
Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice), hepatitis B (known positive HBV surface antigen [HBsAg] result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Participants with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Participants positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV ribonucleic acid (RNA)
Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease (ILD), serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs, or compromise the ability of the participant to give written informed consent
Any unresolved toxicity National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and protocol defined laboratory values
Is a female participant who is pregnant or breastfeeding or male or female participant of reproductive potential who are not willing to employ effective birth control from screening to 120 days after the last dose of study treatment
Participants with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician
