A Phase 3 Global, Multicenter, Double-Blind Randomized Study of Carboplatin-Paclitaxel With INCMGA00012 or Placebo in Participants With Inoperable Locally Recurrent or Metastatic Squamous Cell Carcinoma of the Anal Canal Not Previously Treated With Systemic Chemotherapy (POD1UM-303/InterAACT 2)
EU CTIS ID: 2024-512331-72-00
What this study is testing
To compare the efficacy of carboplatin-paclitaxel with INCMGA00012 versus carboplatin-paclitaxel with placebo in participants with inoperable locally advanced or metastatic SCAC not previously treated with systemic chemotherapy.
- Therapeutic confirmatory (Phase III)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Able to comprehend and willing to sign a written ICF for the study.
- See Appendix D for vaccination-related information.
- Are 18 years of age or older (or as applicable per local country requirements).
- Histologically or cytologically verified, inoperable locally recurrent or metastatic SCAC.
- No prior systemic therapy other than the following: a. Chemotherapy administered concomitantly with radiotherapy as a radiosensitizing agent is permitted. b. Prior neoadjuvant or adjuvant therapy if completed ≥ 6 months before study entry.
- Has measurable disease per RECIST v1.1 as determined by local site investigator/radiology assessment, and after any tissue collected during biopsy. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion.
You likely can't join if
- Has received prior PD-(L)1 directed therapy
- Active infections requiring systemic therapy, or IV antibiotic use up to 7 days before Cycle 1 Day 1. Note: If required by country or local regulations to be tested for COVID19 during screening, a participant should be excluded if they have a positive test result for SARS-CoV-2 infection until both the retest result is negative and clinical recovery is obtained.
- Known hypersensitivity to platinum, paclitaxel, another monoclonal antibody, or any of the excipients that cannot be controlled with standard measures (eg, antihistamines, corticosteroids).
- Participants with impaired cardiac function or clinically significant cardiac disease: a. New York Heart Association Class III or IV cardiac disease, including preexisting clinically significant ventricular arrhythmia, congestive heart failure, or cardiomyopathy. b. Unstable angina pectoris. c. Acute myocardial infarction ≤ 6 months before study participation. d. Other clinically significant heart disease (ie, ≥ uncontrolled Grade 3 hypertension or high-grade conduction disturbance.)
- Participant is pregnant or breastfeeding.
- Has received a live vaccine within 28 days of Cycle 1 Day 1. Note: Examples of live vaccines include but are not limited to measles, mumps, rubella, chicken pox/zoster, yellow fever, rabies, BCG, and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live-attenuated vaccines and are not allowed.

Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion.
- Able and willing to provide adequate tissue sample and whole blood sample with central testing result prior to randomization. Biopsy for archival samples should have occurred within 9 months prior to randomization.
- ECOG performance status 0 to 1.
- If HIV-positive, then must be stable as defined by: a. CD4+ count ≥ 200/μL, b. Undetectable viral load per standard of care assay, c. Receiving antiretroviral therapy (ART/HAART) for at least 4 weeks prior to study enrollment, and have not experienced any HIV-related opportunistic infection for at least 4 weeks prior to study enrollment.
- Willingness to avoid pregnancy or fathering children based on the criteria below. a. Men must agree to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through 120 days after the last dose of INCMGA00012 or placebo or through 180 days after the last dose of chemotherapeutic agents, whichever occurs later (or longer as appropriate based on country-specific requirements) and must refrain from donating sperm during this period. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed. b. Women of childbearing potential must have a negative serum pregnancy test at screening, agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty), and refrain from donating oocytes from screening through 120 days after the last dose of INCMGA00012 or placebo or through 180 days after the last dose of chemotherapeutic agents, whichever occurs later. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed. The definition of WOCBP is located in Appendix A. c. Women of nonchildbearing potential (ie, per Appendix A) are eligible.
