SANOVO Trial

SANOVO (NCT05009836) is a double-blind phase 3 trial in China testing first-line savolitinib plus osimertinib vs osimertinib alone in 326 patients with EGFR-mutant, MET-overexpressing NSCLC. At ESMO 2026 (LBA69), investigator-assessed PFS was 24.9 vs 13.8 months (ITT, HR 0.56). The first-line combination is investigational.

SANOVO Key Takeaways

Primary endpoint met: PFS by investigator, in MET IHC 3+ and ITT

The primary endpoint, investigator-assessed PFS, was tested hierarchically: the MET IHC 3+ population first, then the ITT population (IHC 3+ and IHC 2+). Both were met at the data cutoff of July 31, 2026. In MET IHC 3+ (98 vs 98 patients; median follow-up 30.4 months), median PFS was 24.8 months (95% CI 19.4–27.6) with savolitinib plus osimertinib vs 11.1 months (8.3–16.6) with placebo plus osimertinib: HR 0.45 (0.31–0.66), P < 0.0001. In the ITT population (162 vs 164; median follow-up 38.6 months), median PFS was 24.9 months (22.0–27.6) vs 13.8 months (10.9–16.6): HR 0.56 (0.43–0.74), P < 0.0001. HUTCHMED’s release prints the ITT combination-arm CI as 22.1–27.6.

PFS by independent review (secondary endpoint)

Independent review committee (IRC) assessment, a secondary endpoint, was consistent: MET IHC 3+ median PFS 22.2 months (19.4–NE) vs 13.7 months (8.3–19.4), HR 0.48 (0.32–0.72); ITT 27.9 months (22.1–35.8) vs 16.4 months (9.7–16.6), HR 0.53 (0.39–0.71) (median follow-up 33.1 months). These IRC figures are separate from the primary investigator-assessed results above; the discussant’s first-line comparison slide used the IRC medians (ITT 27.9 vs 16.4 months; IHC 3+ 22.2 vs 13.7 months).

Overall survival (secondary endpoint)

In the ITT population, with 49 (30.2%) vs 83 (50.6%) deaths and 40.5% maturity (median follow-up 38.7 months), median OS was 44.5 months (41.3–NE) vs 34.9 months (26.3–41.1), HR 0.48 (0.33–0.68). OS rates were 94.4% vs 81.0% at 12 months, 79.8% vs 65.4% at 24 months and 67.4% vs 47.4% at 36 months. No P value was reported for OS; the abstract describes a “clinically meaningful OS benefit.” Crossover between arms was not allowed. Subsequent anticancer therapy was given to 46.9% vs 59.1%, including a MET TKI in 1.2% vs 4.3%.

Subgroup HRs are unstratified and exploratory; several confidence intervals cross 1, including MET IHC 2+. The unstratified IHC 3+ subgroup HR (0.52) differs from the stratified primary-analysis HR in the IHC 3+ population (0.45). The presenter’s slide reports a consistent PFS benefit across ITT subgroups.

Regulatory status & clinical implications

⚠ Investigational in first line. Savolitinib plus osimertinib is not approved for first-line EGFR-mutant NSCLC anywhere; HUTCHMED plans a supplemental NDA in China based on SANOVO. Savolitinib (ORPATHYS®, HUTCHMED; commercialized by AstraZeneca) is not FDA approved. In China it is approved with osimertinib for EGFR-mutant non-squamous NSCLC with MET amplification after EGFR-TKI therapy (SACHI), for MET exon 14 skipping NSCLC, and conditionally for MET-amplified gastric or gastroesophageal junction adenocarcinoma after at least two prior systemic therapies. ✓ Osimertinib (TAGRISSO®, AstraZeneca) alone is FDA approved for first-line EGFR-mutant NSCLC. All patients were enrolled in China. The combination after osimertinib was tested separately in SAFFRON.

[Conclusions] The combination of Savo + Osi showed statistically significant and clinically meaningful improvements in PFS over Osi alone in untreated advanced NSCLC patients harboring activating EGFRm and MET overexpression. PFS in MET IHC 3+: 24.8 mo vs 11.1 mo (HR=0.45, p<0.0001). PFS in ITT population: 24.9 mo vs 13.8 mo (HR=0.56, p<0.0001). All secondary endpoints ORR, DoR and OS supported the PFS findings, with clinically meaningful improvement in OS. mOS in ITT: 44.5 mo vs 34.9 mo, HR = 0.48. Overall, savolitinib + osimertinib demonstrated a tolerable and manageable safety profile consistent with the known profiles of the individual agents and the combination, and no new safety concerns identified. Osimertinib plus savolitinib provides an effective, oral, biomarker-directed treatment approach and establishes a new first-line treatment option for patients with EGFRm and MET-overexpressed advanced NSCLC.

Slide text (transcribed from the slide images) [Invited discussion, Rebecca S. Heist: "Has EGFR MET its match?"] Questions: What is the right MET definition in the 1L population? Is there benefit in the 2+ population? How does a MET selected population fare with FLAURA2 or MARIPOSA regimen? What resistance will emerge from SANOVO combination? Phase 3 SANOVO: Savolitinib or Placebo Combined with Osimertinib in Treatment-Naive Advanced NSCLC with EGFR Mutation and MET Overexpression (design slide, Wu et al ESMO 2026), with the inclusion criteria IHC 3+ (>=90% of tumor cells demonstrating strong staining) or IHC 2+ (H-score >=220 and <90% of tumor cells demonstrating strong staining) circled.

What physicians are debating

Who counts as MET-positive? The IHC 2+ question

The ITT population included IHC 3+ (≥90% of tumor cells with strong staining) and IHC 2+ (H-score ≥220). Riyaz Shah, MD, called it “3+ or 2+ (interesting definition)”. In the investigator-assessed subgroup analysis the IHC 2+ HR was 0.85 (0.57–1.27), and the discussant, Rebecca Heist, MD, asked “Is there benefit in the 2+ population?” and “What is the right MET definition in the 1L population?” Ryan Gentzler, MD, noted “Questions remain around how to test for MET positivity (IHC, amplification, cutoffs)”.

Invited discussant slides (Rebecca S. Heist, ESMO 2026) · LBA69 presentation slides (Yi-Long Wu, ESMO 2026)

Screening burden and testing

Of 1,896 patients screened, 1,449 had a successful MET IHC test and 326 were randomized. Tom John, MD, wrote “Number of patients screened is enormous”; Antonio Calles, MD, pointed to “High attrition to find MET-IHC3+”; Balazs Halmos, MD, wrote that “Testing/rebiopsies/figuring out the right test/threshold will be key!”

LBA69 presentation slides (Yi-Long Wu, ESMO 2026)

Comparator: osimertinib alone, not FLAURA2 or MARIPOSA

The control arm was osimertinib plus placebo. Heist asked “How does a MET selected population fare with FLAURA2 or MARIPOSA regimen?” and set SANOVO beside FLAURA, FLAURA2 and MARIPOSA on one slide (cross-trial, different populations). Calles wondered “how this data compares to this subset of patients in the MARIPOSA trial”; Adam Januszewski, MD, asked “Target MET in 1L or 2L? Amivantimab already targets MET.” Tom John noted that the osimertinib arm did worse than usual: “increased MET has much worse PFS to what we usually see with Osi.”

Invited discussant slides (Rebecca S. Heist, ESMO 2026)

Toxicity of the combination

Grade ≥3 events (77.2% vs 38.4%), serious events (54.9% vs 28.7%) and discontinuations (14.8% vs 4.3%) were higher with savolitinib, with longer exposure (22.1 vs 12.9 months). Calles wrote of “the cost of more MET-related side effects”; Heist’s discussion contrasted the SANOVO profile (peripheral edema, hypoalbuminemia, platelet decrease, anemia) with MARIPOSA and FLAURA2, and asked “What resistance will emerge from SANOVO combination?”

LBA69 presentation slides (Yi-Long Wu, ESMO 2026) · Invited discussant slides (Rebecca S. Heist, ESMO 2026)

First line or at resistance?

The same combination already improved PFS and OS after osimertinib in SAFFRON (presented the day before) and is approved in China at resistance (SACHI). Halmos called the answer “a resounding yes in 2nd line” with “a promising potential in 1st line based on the surprisingly positive results of the SANOVO trial”; Gentzler wrote of “compelling data first line for those with de novo MET.” SANOVO enrolled patients in China only.

מה עושים כשהגידול מתקדם לאחר טיפול בטגריסו? כיצד ניתן לתקוף את מנגנון העמידות שלו? סקירה של מחקרי SAFFRON, SANOVO מכנס #ESMO2026 #ESMO26 והשווה למחקר MARIPOSA-2 הקודם: אחד ממנגנוני העמידות המרכזיים שמפתחים בחולי NSCLC עם מוטציית EGFR תחת טיפול בטגריסו הוא הפעלה של מסלול MET זיהוי מדויק של מנגנון זה מאפשר היום לשקול טיפול ממוקד במקום מעבר לכימותרפיה 1. מחקר SAFFRON טיפול ממוקד לאחר התקדמות על בטגריסו במחקר פאזה III הגלובלי SAFFRON הושווה השילוב osimertinib + savolitinib לכימותרפיה מבוססת פלטינום ואלימטה, בחולים עם NSCLC מתקדם הנושא מוטציית EGFR, שמחלתם התקדמה לאחר osimertinib ושבגידולם נמצא ביטוי־יתר משמעותי של MET ו/או הגברה של הגן MET. התוצאות המרכזיות: - mPFS: 7.6 לעומת 5.4 חודשים; HR 0.55 - mOS: 17.8 לעומת 12.9 חודשים; HR 0.68 - ORR: 51% לעומת 27% - הישרדות לאחר שנה: 70% לעומת 53% היתרון היה מובהק סטטיסטית הן ב־PFS והן ב־OS. זהו ממצא משמעותי, משום שמדובר במחקר פאזה III גלובלי שהדגים תועלת בשני מדדים אלה באוכלוסייה שנבחרה על בסיס מנגנון עמידות מוגדר. בנוסף, מדובר בשילוב פומי, מה שעשוי להיות יתרון מבחינת נוחות הטיפול. 2. איך SAFFRON משתווה ל־MARIPOSA-2? מחקר MARIPOSA-2 הוא מחקר פאזה III שבחן גישה אחרת לאחר התקדמות על טגריסו הוספת amivantamab (נוגדן דו־ספציפי המכוון ל־EGFR ול־MET) לכימותרפיה מבוססת carboplatin ו־pemetrexed. בניגוד ל־SAFFRON, המחקר לא הגביל את ההשתתפות לחולים עם ביטוי־יתר או הגברה של MET, אלא כלל חולים עם מוטציות EGFR שכיחות (בעיקר exon 19 deletion ו־L858R). בזרוע amivantamab + כימותרפיה, לעומת כימותרפיה בלבד: - mPFS: 6.3 לעומת 4.2 חודשים; HR 0.48 - ORR: 64% לעומת 36% - mOS: 17.7 לעומת 15.3 חודשים; HR 0.73 חשוב לדייק לגבי ההישרדות הכוללת: בניתוח הביניים השני התקבל p=0.039, אך התוצאה לא עברה את סף המובהקות הסטטיסטית שהוגדר מראש. לכן אין להציג את יתרון ה־OS כיתרון מובהק לפי תכנון המחקר. בזרוע נפרדת נבחן גם שילוב amivantamab + lazertinib + כימותרפיה (mPFS 8.3 מול 4.2 חודשים, HR 0.44), אך יש להביא בחשבון את פרופיל הרעילות של המשטר המשולש. ההבדל הקליני בין המחקרים מחקר SAFFRON מתמקד באוכלוסייה נבחרת שבה הודגם מנגנון עמידות הקשור ל־MET, ובוחן שתי תרופות ממוקדות הניתנות דרך הפה. MARIPOSA-2 מציע אפשרות רחבה יותר לאחר osimertinib, ללא צורך בבחירת חולים על בסיס MET, אך כולל טיפול תוך־ורידי עם פרופיל רעילות שונה. 3. SANOVO האם נכון לחסום EGFR ו־MET כבר בקו הראשון? מחקר SANOVO בחן האם יש יתרון להתערבות מוקדמת, עוד לפני הופעת עמידות ל־osimertinib. במחקר פאזה III שנערך בסין נכללו חולים שטרם טופלו במחלתם המתקדמת, עם מוטציית EGFR וביטוי־יתר של MET (IHC 2+ או 3+). המשתתפים קיבלו טגירסו + savolitinib או טגריסו בלבד. התוצאות שהוצגו ב־ESMO 2026: - באוכלוסייה הכוללת: mPFS 24.9 לעומת 13.8 חודשים; HR 0.56 - בתת־הקבוצה עם IHC 3+ גבוה: mPFS 24.8 לעומת 11.1 חודשים; HR 0.45 - ב־OS דווח HR של 0.48, עם חציון OS של 44.5 לעומת 34.9 חודשים אלה נתונים מעודדים, התומכים באפשרות של חסימה כפולה ומוקדמת בחולים שנבחרו לפי ביומרקר. עם זאת, SANOVO נערך בסין והשווה את השילוב ל־osimertinib בלבד. בהקשר הרחב יותר של קו ראשון כבר קיימות אפשרויות שילוב אחרות (כמו osimertinib + כימותרפיה ב־FLAURA2 או amivantamab + lazertinib ב־MARIPOSA), ולכן נדרשת בחינה נוספת של מקומו בפרדיגמה הטיפולית. *חשוב לזכור שביטוי־יתר של MET לפי IHC והגברה של הגן MET אינם ממצאים זהים, ויש להתייחס לספי ההגדרה ולשיטות הבדיקה שבהן השתמש כל מחקר. בשורה התחתונה: האתגר הקליני כעת הוא לא רק להוסיף עוד טיפולים יעילים, אלא להתאים לכל מטופל את הגישה המתאימה לפי סטטוס MET, קו הטיפול, פרופיל הרעילות, נוחות הטיפול והזמינות🙏

SANOVO Trial Design

SANOVO asked whether adding savolitinib, an oral, selective MET tyrosine kinase inhibitor, to osimertinib improves progression-free survival as first-line treatment for EGFR-mutant advanced NSCLC with MET overexpression, a group with shorter benefit from EGFR-TKI monotherapy. The trial is run by HUTCHMED (CT.gov sponsor) and funded by HUTCHMED and AstraZeneca.

Study Design

Randomized 1:1, double-blind, placebo-controlled phase 3 at 74 centers in China (NCT05009836). 326 randomized (162 vs 164), enrollment August 2022 to August 2025. Stratified by EGFR mutation type, MET status (IHC 3+ vs 2+) and brain metastases. Crossover not allowed.

Population

Untreated unresectable or metastatic NSCLC; EGFR exon 19 deletion or L858R; centrally confirmed MET overexpression by IHC (D1C2, Amoy Diagnostics): IHC 3+ (≥90% of tumor cells with strong staining) or IHC 2+ (H-score ≥220 and <90% strong staining); ECOG PS 0–1. 196 patients (98 per arm) were IHC 3+; brain metastases at baseline 38.9% vs 40.2%.

Interventions

Savolitinib 300 mg or 200 mg twice daily (by body weight) or matching placebo, plus osimertinib 80 mg once daily, until progression or intolerable toxicity.

Endpoints

Primary: investigator-assessed PFS (RECIST 1.1), tested hierarchically in MET IHC 3+ then ITT. Secondary: IRC-assessed PFS; ORR, DoR and DCR by investigator and IRC; OS; safety.

Presenter & Discussant

Presenter: Yi-Long Wu, MD (Guangdong Provincial People’s Hospital), lead principal investigator. Invited discussant (LBA69 and 2615O): Rebecca S. Heist, MD (Massachusetts General Hospital).

Data Cut

Data cutoff July 31, 2026. Median follow-up for PFS 30.4 months (IHC 3+) and 38.6 months (ITT, investigator); for OS 38.7 months, OS maturity 40.5%.

SANOVO in the News

SANOVO Questions

What is the SANOVO trial?

SANOVO (NCT05009836) is a randomized, double-blind phase 3 trial at 74 centers in China, run by HUTCHMED, comparing savolitinib (a MET inhibitor) plus osimertinib with placebo plus osimertinib as first-line treatment in 326 patients with EGFR-mutant (exon 19 deletion or L858R) advanced NSCLC and centrally confirmed MET overexpression (IHC 3+ or IHC 2+). Design: Trial Design.

What did SANOVO show at ESMO 2026?

At the data cutoff of July 31, 2026, investigator-assessed PFS, the primary endpoint, improved in both hierarchically tested populations: MET IHC 3+ 24.8 vs 11.1 months, HR 0.45 (95% CI 0.31–0.66), and ITT 24.9 vs 13.8 months, HR 0.56 (0.43–0.74), both P < 0.0001. Median OS, a secondary endpoint, was 44.5 vs 34.9 months, HR 0.48 (0.33–0.68), at 40.5% maturity; no OS P value was reported. Figures: At a Glance.

How is SANOVO different from SAFFRON?

SANOVO tested savolitinib plus osimertinib as first-line treatment in untreated, MET-overexpressing EGFR-mutant NSCLC, against osimertinib alone. SAFFRON tested the same combination after progression on osimertinib, against platinum-pemetrexed, in patients with MET overexpression or amplification. Different setting, comparator and biomarker definition. See SAFFRON.

Is savolitinib plus osimertinib approved for first-line use?

No. The first-line combination is investigational everywhere; HUTCHMED plans a supplemental NDA in China based on SANOVO. Savolitinib is not FDA approved. In China it is approved with osimertinib for EGFR-mutant non-squamous NSCLC with MET amplification after EGFR-TKI therapy (SACHI), and alone for MET exon 14 skipping NSCLC. Osimertinib alone is FDA approved for first-line EGFR-mutant NSCLC.

What were the main side effects?

Grade ≥3 treatment-emergent adverse events occurred in 77.2% vs 38.4%, serious events in 54.9% vs 28.7%, and events leading to discontinuation in 14.8% vs 4.3%; fatal events (excluding progression) were 4.3% vs 4.8%. Median exposure was 22.1 vs 12.9 months. The most common events with the combination were peripheral edema (65%), hypoalbuminemia (63%), decreased platelet count (51%) and anemia (49%).

Oct 26, 2026 ● POSITIVE 🚨 #ESMO26 SANOVO Ph3 🇨🇳 (China-only) Impressive 1L savolitinib + osimertinib in EGFRm/MET-OE NSCLC: 📈 PFS 24.9 vs 13.8m (HR 0.56) 📈 OS 44.5 vs 34.9m (HR 0.48) MET is a key target! ❓Target MET in 1L or 2L? Amivantimab already targets MET. Efficacy similar. Tox will be key https://t.co/F1i5HLPGRM
Oct 26, 2026 ● NEUTRAL מה עושים כשהגידול מתקדם לאחר טיפול בטגריסו? כיצד ניתן לתקוף את מנגנון העמידות שלו? סקירה של מחקרי SAFFRON, SANOVO מכנס #ESMO2026 #ESMO26 והשווה למחקר MARIPOSA-2 הקודם: אחד ממנגנוני העמידות המרכזיים שמפתחים בחולי NSCLC עם מוטציית EGFR תחת טיפול בטגריסו הוא הפעלה של מסלול MET זיהוי מדויק של מנגנון זה מאפשר היום לשקול טיפול ממוקד במקום מעבר לכימותרפיה 1. מחקר SAFFRON טיפול ממוקד לאחר התקדמות על בטגריסו במחקר פאזה III הגלובלי SAFFRON הושווה השילוב osimertinib + savolitinib לכימותרפיה מבוססת פלטינום ואלימטה, בחולים עם NSCLC מתקדם הנושא מוטציית EGFR, שמחלתם התקדמה לאחר osimertinib ושבגידולם נמצא ביטוי־יתר משמעותי של MET ו/או הגברה של הגן MET. התוצאות המרכזיות: - mPFS: 7.6 לעומת 5.4 חודשים; HR 0.55 - mOS: 17.8 לעומת 12.9 חודשים; HR 0.68 - ORR: 51% לעומת 27% - הישרדות לאחר שנה: 70% לעומת 53% היתרון היה מובהק סטטיסטית הן ב־PFS והן ב־OS. זהו ממצא משמעותי, משום שמדובר במחקר פאזה III גלובלי שהדגים תועלת בשני מדדים אלה באוכלוסייה שנבחרה על בסיס מנגנון עמידות מוגדר. בנוסף, מדובר בשילוב פומי, מה שעשוי להיות יתרון מבחינת נוחות הטיפול. 2. איך SAFFRON משתווה ל־MARIPOSA-2? מחקר MARIPOSA-2 הוא מחקר פאזה III שבחן גישה אחרת לאחר התקדמות על טגריסו הוספת amivantamab (נוגדן דו־ספציפי המכוון ל־EGFR ול־MET) לכימותרפיה מבוססת carboplatin ו־pemetrexed. בניגוד ל־SAFFRON, המחקר לא הגביל את ההשתתפות לחולים עם ביטוי־יתר או הגברה של MET, אלא כלל חולים עם מוטציות EGFR שכיחות (בעיקר exon 19 deletion ו־L858R). בזרוע amivantamab + כימותרפיה, לעומת כימותרפיה בלבד: - mPFS: 6.3 לעומת 4.2 חודשים; HR 0.48 - ORR: 64% לעומת 36% - mOS: 17.7 לעומת 15.3 חודשים; HR 0.73 חשוב לדייק לגבי ההישרדות הכוללת: בניתוח הביניים השני התקבל p=0.039, אך התוצאה לא עברה את סף המובהקות הסטטיסטית שהוגדר מראש. לכן אין להציג את יתרון ה־OS כיתרון מובהק לפי תכנון המחקר. בזרוע נפרדת נבחן גם שילוב amivantamab + lazertinib + כימותרפיה (mPFS 8.3 מול 4.2 חודשים, HR 0.44), אך יש להביא בחשבון את פרופיל הרעילות של המשטר המשולש. ההבדל הקליני בין המחקרים מחקר SAFFRON מתמקד באוכלוסייה נבחרת שבה הודגם מנגנון עמידות הקשור ל־MET, ובוחן שתי תרופות ממוקדות הניתנות דרך הפה. MARIPOSA-2 מציע אפשרות רחבה יותר לאחר osimertinib, ללא צורך בבחירת חולים על בסיס MET, אך כולל טיפול תוך־ורידי עם פרופיל רעילות שונה. 3. SANOVO האם נכון לחסום EGFR ו־MET כבר בקו הראשון? מחקר SANOVO בחן האם יש יתרון להתערבות מוקדמת, עוד לפני הופעת עמידות ל־osimertinib. במחקר פאזה III שנערך בסין נכללו חולים שטרם טופלו במחלתם המתקדמת, עם מוטציית EGFR וביטוי־יתר של MET (IHC 2+ או 3+). המשתתפים קיבלו טגירסו + savolitinib או טגריסו בלבד. התוצאות שהוצגו ב־ESMO 2026: - באוכלוסייה הכוללת: mPFS 24.9 לעומת 13.8 חודשים; HR 0.56 - בתת־הקבוצה עם IHC 3+ גבוה: mPFS 24.8 לעומת 11.1 חודשים; HR 0.45 - ב־OS דווח HR של 0.48, עם חציון OS של 44.5 לעומת 34.9 חודשים אלה נתונים מעודדים, התומכים באפשרות של חסימה כפולה ומוקדמת בחולים שנבחרו לפי ביומרקר. עם זאת, SANOVO נערך בסין והשווה את השילוב ל־osimertinib בלבד. בהקשר הרחב יותר של קו ראשון כבר קיימות אפשרויות שילוב אחרות (כמו osimertinib + כימותרפיה ב־FLAURA2 או amivantamab + lazertinib ב־MARIPOSA), ולכן נדרשת בחינה נוספת של מקומו בפרדיגמה הטיפולית. *חשוב לזכור שביטוי־יתר של MET לפי IHC והגברה של הגן MET אינם ממצאים זהים, ויש להתייחס לספי ההגדרה ולשיטות הבדיקה שבהן השתמש כל מחקר. בשורה התחתונה: האתגר הקליני כעת הוא לא רק להוסיף עוד טיפולים יעילים, אלא להתאים לכל מטופל את הגישה המתאימה לפי סטטוס MET, קו הטיפול, פרופיל הרעילות, נוחות הטיפול והזמינות🙏
