Beskrivelse
Inclusion Criteria:
- Adult patients (≥ 18 years) who received at least one dose of Envafolimab under the NPP between June, 2025 and Dec 31, 2026.
- Histologically or cytologically confirmed diagnosis of a malignancy for which Envafolimab was prescribed under the NPP (e.g., an advanced solid tumor with MSI-H/dMMR or other approved/compassionate indications).
- Measurable or evaluable disease at baseline, with at least one disease assessment (e.g. imaging or clinical evaluation) performed within 8 weeks before the first Envafolimab dose (to establish baseline tumor status).
- At least one post-baseline disease assessment after starting Envafolimab, and a minimum follow-up duration of 6 months from the first dose (unless the patient has documented disease progression or died within 6 months).
- Availability of sufficient clinical data in the medical records to evaluate baseline characteristics, treatment administration, tumor response, and safety outcomes. This includes baseline demographics, disease status, treatment dates, and follow-up assessments as required by the CRF.
- Permission/approval for data use: Patient data can be utilized for research as per local ethical and regulatory requirements (e.g., institutional review board approval or waiver of consent for retrospective data collection, and compliance with data privacy laws).
Exclusion Criteria:
- No evidence of Envafolimab administration: Patients for whom Envafolimab was requested or planned under NPP but never actually received a dose.
- Insufficient follow-up: Patients with no post-baseline tumor assessment and less than 6 months of follow-up without documented disease progression or death. (Such patients would not contribute evaluable data for effectiveness.)
- Missing critical baseline information in records, such as unknown index (start) date of Envafolimab therapy or lack of documented cancer diagnosis, precluding assessment of outcomes.
- Prior Envafolimab exposure outside the NPP (e.g., via a clinical trial or other program) before the index date, unless specifically allowed (pre-specified exceptions, if any, will be outlined for instance, patients who switched from a clinical trial to NPP might be handled on a case by case basis).
- Concurrent participation in any other interventional clinical trial at the time of starting Envafolimab (index date), to avoid confounding effects of other investigational treatments on outcomes.
- Legal or ethical prohibitions on using the patient's data for research. For example, if local regulations or the patient's prior consent status prevent inclusion of their de-identified data in this study, they will not be enrolled.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Disease Control Rate (DCR)
Tidsramme: From first dose through up to 6 months follow-up
|
: The proportion of patients who achieve CR, PR, or Stable Disease (SD) as the best response.
DCR provides a measure of the fraction of patients who derive any tumor control (no progression) from the therapy.
|
From first dose through up to 6 months follow-up
|
|
Progression-Free Survival (PFS)
Tidsramme: From first dose through up to 6 months follow-up
|
: Defined as the time from first Envafolimab dose to the first occurrence of disease progression or death from any cause, whichever occurs first.
PFS for each patient (in months) will be calculated based on dates recorded in the CRF.
Patients without documented progression who are alive at the last follow-up will be censored at the date of the previous disease assessment.
|
From first dose through up to 6 months follow-up
|
|
Overall Survival (OS)
Tidsramme: From first dose through up to 6 months follow-up
|
Defined as the time from first Envafolimab dose to death from any cause.
OS (in months) will be determined for each patient; living patients will be censored at the date of last contact or last known alive date.
|
From first dose through up to 6 months follow-up

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Incidence of Treatment-Emergent Adverse Events (TEAEs)
Tidsramme: From first dose through up to 6 months follow-up
|
The proportion of patients experiencing any adverse event (of any grade) during the observation period after starting Envafolimab.
This will be captured by whether "Any Adverse Events reported" is marked on the CRF.
|
From first dose through up to 6 months follow-up
|
|
Incidence of Grade ≥3 AEs
Tidsramme: From first dose through up to 6 months follow-up
|
The frequency of patients who experienced severe or lifethreatening adverse events (Grade 3 or higher, as per CTCAE v5.0) during Envafolimab treatment.
|
From first dose through up to 6 months follow-up
|
|
Incidence of Serious Adverse Events (SAEs)
Tidsramme: From first dose through up to 6 months follow-up
|
The proportion of patients with any serious adverse event (as defined by standard criteria: results in death, is life-threatening, requires/prolongs hospitalization, or other medically important events) reported during treatment.
|
From first dose through up to 6 months follow-up
|
|
Incidence of immune-related adverse events (irAEs)
Tidsramme: From first dose through up to 6 months follow-up
|
The proportion of patients who experienced immune-mediated toxicities (e.g., autoimmune manifestations such as pneumonitis, colitis, etc.) attributed to Envafolimab.
|
From first dose through up to 6 months follow-up
|
|
Treatment discontinuation due to AEs
Tidsramme: From first dose through up to 6 months follow-up
|
The percentage of patients who had Envafolimab therapy permanently stopped as a result of adverse events.
|
From first dose through up to 6 months follow-up
