Study summary

The NEWLINE trial is a multicenter, randomized, open-label, blinded endpoint (PROBE) trial evaluating whether adjunctive low-dose intra-arterial alteplase administered immediately after successful endovascular thrombectomy improves functional outcomes in adults with acute ischemic stroke due to anterior circulation large vessel occlusion. Eligible participants achieving successful reperfusion (eTICI 2b-3) within 24 hours of symptom onset will be randomized 1:1 to receive intra-arterial alteplase plus standard care or standard care alone. The primary outcome is excellent functional outcome (modified Rankin Scale score 0-1) at 90 days.

Read the detailed description

Acute ischemic stroke caused by anterior circulation large vessel occlusion is commonly treated with endovascular thrombectomy (EVT), which achieves successful reperfusion in approximately 85-90% of treated patients. Despite successful reperfusion, many patients remain functionally disabled because of persistent microvascular obstruction, distal embolization, incomplete tissue reperfusion (the "no-reflow" phenomenon), and ischemia-reperfusion injury.

The NEWLINE trial is a prospective, multicenter, randomized, open-label, blinded endpoint (PROBE) trial designed to evaluate whether adjunctive low-dose intra-arterial alteplase administered immediately after successful EVT improves functional outcomes compared with standard medical care alone. Eligible adults with acute ischemic stroke due to anterior circulation large vessel occlusion who achieve successful reperfusion (expanded Thrombolysis in Cerebral Infarction [eTICI] grade 2b-3) within 24 hours of symptom onset will be randomly assigned in a 1:1 ratio to receive either adjunctive intra-arterial alteplase plus standard care or standard care alone.

The primary efficacy outcome is the proportion of participants achieving excellent functional outcome, defined as a modified Rankin Scale (mRS) score of 0-1, at 90 days after randomization. Key safety outcomes include symptomatic intracranial hemorrhage and all-cause mortality. The trial aims to determine whether adjunctive intra-arterial alteplase enhances neurological recovery after successful EVT without increasing the risk of major hemorrhagic complications or death.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

What researchers measure

Primary outcomes

  1. Modified Rankin Scale at day 90

    Proportion of participants achieving a Modified Rankin Scale (mRS) score of 0 or 1 at 90 days (±15 days). The Modified Rankin Scale ranges from 0 (no symptoms) to 6 (death). Lower scores indicate better functional outcomes; higher scores indicate worse disability.

    Time frame: 90 days post treatment

  2. SAFETY OUTCOME: symptomatic intracerebral hemorrahge (sICH ) rate at 24 hours.

    Symptomatic intracranial hemorrhage (sICH) will be classified according to the Heidelberg Bleeding Classification.

    Time frame: 24hours post EVT

Secondary outcomes

  1. The shift analysis of 90-day mRS

    Shift analysis of the modified Rankin Scale (mRS) at Day 90 (scores range from 0 to 6, with mRS scores of 5 and 6 combined into a single category representing a very poor outcome; higher scores indicate worse functional outcomes).

    Time frame: day 90 post treatment

  2. SAFETY OUTCOME: Mortality at 90 days

    Mortality at 90 days

    Time frame: Day 90 post endovascular treatment

  3. Quality of life at 90 days

    Quality of life at 90 days (±15 days), measured using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire. The EQ VAS ranges from 0 (worst imaginable health) to 100 (best imaginable health), with higher scores indicating better health-related quality of life.

    Time frame: day 90 post treatment

  4. NIHSS at 24h

    The proportion of NIHSS 0-1 or ≥10 points reduction at 24 ±12 hours

    Time frame: 24 ±12 hours post EVT

  5. mRS 0-2 at 90 day

    The proportion of mRS 0-2 at 90 ± 15 days

    Time frame: 90 day post EVT

  6. Any ICH

    Any ICH within 24 ± 12 hours (Heidelberg criteria)

    Time frame: 24 hour post EVT

  7. Final eTICI reperfusion grade

    Reperfusion will be assessed on the final digital subtraction angiogram using the expanded Thrombolysis in Cerebral Infarction (eTICI) grading scale. The eTICI scale ranges from 0 (no reperfusion) to 3 (complete reperfusion). Higher grades indicate better angiographic reperfusion.

    Time frame: Immediately after completion of intra-arterial alteplase administration.

  8. To evaluate the incremental cost-effectiveness and cost-utility of adjunctive intra-arterial thrombolysis following successful angiographic reperfusion.

    Incremental cost-effectiveness and cost-utility of adjunctive intra-arterial thrombolysis following successful angiographic reperfusion, expressed as the incremental cost per quality-adjusted life-year (QALY) gained compared with standard care.

    Time frame: 12 months ± 1 month

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2026 (actual). Primary completion is estimated for Dec 2028, 28 months after the start.

Of 143 non-industry phase 3 interventional studies under Ischemic Stroke, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 62. This study's planned 28 months is below that.

Counting every sponsor, half of 165 studies reached it within 30 months; a quarter within 19 and three quarters within 52.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
