Nogapendekin Alfa Inbakicept · 3 trials · 8 indications
Progression-free survival (PFS) as assessed by RECIST 1.1 criteria comparing the experimental treatment arm with the standard-of-care control arm in participants with locally advanced HPV-positive oropharyngeal squamous cell carcinoma (OPSCC).
Proportion of participants who die from any cause within 28 days of randomization
Proportion of participants who are alive 28 days after the first dose of nogapendekin alfa inbakicept (NAI). Survival status will be determined by review of hospital records and/or direct contact (in person or by phone) on Day 28 after Day 1 dosing.
| Arm | Type | Description |
|---|---|---|
| Phase 2a, Single Arm (Safety Lead-In) | EXPERIMENTAL | Participants will receive neoadjuvant nogapendekin alfa inbakicept (NAI), hAd5-HPV vaccine (IBRX-042), and nab-paclitaxel followed by de-intensified intensity-modulated radiation therapy (IMRT) with concurrent cisplatin, and post-radiation NAI and IBRX-042 during the Phase 2a safety lead-in portion of the study. |
| Arm A | EXPERIMENTAL | Participants will receive neoadjuvant nogapendekin alfa inbakicept (NAI), hAd5-HPV vaccine (IBRX-042), and nab-paclitaxel followed by de-intensified intensity-modulated radiation therapy (IMRT) with concurrent cisplatin, and post-radiation NAI and IBRX-042. |
| Arm B | ACTIVE_COMPARATOR | Participants will receive standard-of-care intensity-modulated radiation therapy (IMRT) with concurrent cisplatin for locally advanced HPV-positive oropharyngeal squamous cell carcinoma (OPSCC). |
| NAI + Standard of Care | EXPERIMENTAL | NAI 1.2 mg subcutaneous injection administered on Days 3 (or earlier if ALC \<700 cells/µL), Day 14, and Day 21 if needed for ALC \<1,000 cells/µL, plus institutional standard of care for sepsis |
| Standard of Care Alone | ACTIVE_COMPARATOR | Institutional standard of care for sepsis including antimicrobial therapy, fluid resuscitation, vasopressor support, and mechanical ventilation as clinically indicated |
| NAI Plus Standard of Care | EXPERIMENTAL | Critically ill adults with sepsis or septic shock per Sepsis-3 criteria and persistent lymphopenia (ALC ≤ 1,000 cells/µL in two measurements ≥ 12 hours apart) will receive protocolized standard of care plus NAI 1.2 mg subcutaneously on Day 1, with optional doses on Day 14 and Day 21 if still hospitalized (and ALC ≤ 1,000 for Day 21), with monitoring for safety and clinical outcomes for 90 days. |

Nogapendekin Alfa Inbakicept (NAI) is an investigational drug being studied for HPV-Positive Oropharyngeal Squamous Cell Carcinoma and Sepsis. In oncology, it is being evaluated in combination with an HPV vaccine and nab-paclitaxel for HPV-positive oropharyngeal cancer. For sepsis, it is being studied in critically ill adults with persistent lymphopenia.
Nogapendekin Alfa Inbakicept is an agonist that targets IL2RG, IL2RB, and IL15RA. These are receptor components involved in immune cell signaling. By activating these targets, the drug is designed to modulate immune responses, which is relevant to its investigational use in oncology and sepsis.
Nogapendekin Alfa Inbakicept is being developed by ImmunityBio, Inc., a biopharmaceutical company. ImmunityBio's stock trades under the ticker symbol IBRX on the stock market.
Nogapendekin Alfa Inbakicept is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Two Phase 2 trials are planned, and one Phase 1 trial is also listed, all currently in the not-yet-recruiting stage.
Nogapendekin Alfa Inbakicept is involved in three clinical trials. NCT07578558 is a Phase 2 study for sepsis with persistent lymphopenia. NCT07628062 is a Phase 2 study for HPV-positive oropharyngeal cancer. NCT07783789 is a Phase 1 study for sepsis and septic shock. All trials are not yet recruiting.
Yes, Nogapendekin Alfa Inbakicept is also known as NAI. The abbreviation NAI is used interchangeably with the full drug name in clinical trial documentation and research contexts.
