It has been studied mainly in metastatic breast cancer, advanced non-small-cell lung cancer (NSCLC), and platinum-sensitive recurrent ovarian cancer, in both first-line and later-line settings, including after anthracycline or taxane exposure.[1](https://clinicaltrials.gov/study/NCT00192062) It is not an FDA-approved regimen: the gemcitabine label lists only carboplatin, paclitaxel, and cisplatin combinations, so the evidence base consists of phase I to III trials and registry records rather than regulatory labeling.[2](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=06dd9d40-74fc-4409-93b1-a46be7126331)\n\n| Key fact | Value |\n|---|---|\n| Regulatory status | Off-label/investigational combination; gemcitabine label names only carboplatin, paclitaxel, and cisplatin partners[2](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=06dd9d40-74fc-4409-93b1-a46be7126331) |\n| Common schedule | Gemcitabine 1000–1200 mg/m² plus vinorelbine 25 mg/m² IV on days 1 and 8 of a 21-day cycle[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) • [4](https://karger.com/che/article/62/5/307/66454/Gemcitabine-and-Vinorelbine-Combination) |\n| Oral variant | Vinorelbine 60 mg/m² orally (comparable to 25 mg/m² IV) plus gemcitabine 1000 mg/m² IV, days 1 and 8[5](https://www.nature.com/articles/bjc2012284) |\n| Breast cancer, phase III | PFS 6.0 vs 4.0 months vs vinorelbine alone (HR 0.66, p=0.0028); OS 15.9 vs 16.4 months (p=0.8046)[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) |\n| NSCLC, phase III | Median survival 32 weeks vs 38 weeks for cisplatin-based doublets[6](https://ascopubs.org/doi/10.1200/JCO.2003.06.099) |\n| Ovarian cancer, phase II | Overall response rate 48.7% in platinum-sensitive recurrence; grade 3/4 neutropenia 23%[7](https://ijgc.bmj.com/content/19/9/1529) |\n| Toxicity | Grade 3–4 neutropenia 61% in the GEICAM combination arm[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) |\n\n## How it works\n\nVinorelbine is a semi-synthetic vinca alkaloid that induces cytotoxicity by inhibiting microtubule assembly, arresting cells at the G2-M phase of the cell cycle.[8](https://pmc.ncbi.nlm.nih.gov/articles/PMC3982182/) The published rationale for pairing them rests on three points stated in the phase I/II literature: the two drugs have different mechanisms of anti-tumor activity, good therapeutic indices, and no overlapping toxicities except neutropenia; and both appear non-cross-resistant with anthracyclines and taxanes, which made the combination a candidate for patients previously treated with those classes.[8](https://pmc.ncbi.nlm.nih.gov/articles/PMC3982182/)\n\nThe trials cited below test whether the non-overlapping mechanisms translate into better outcomes, and the phase III results show progression-free survival gains without overall survival gains.\n\n## How it is done\n\nThe most studied intravenous schedule gives gemcitabine 1000–1200 mg/m² with vinorelbine 25 mg/m² on days 1 and 8 of every 21-day cycle. Examples include the GEICAM phase III trial (gemcitabine 1200 mg/m² plus vinorelbine 30 mg/m²)[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) and the KMBOG 1015 study in taxane-pretreated HER2-negative breast cancer (1200/25 mg/m²).[4](https://karger.com/che/article/62/5/307/66454/Gemcitabine-and-Vinorelbine-Combination) The FDA-approved gemcitabine infusion time is 30 minutes; the label specifies 1000–1250 mg/m² over 30 minutes on days 1 and 8 of 21-day cycles, or days 1, 8, and 15 of 28-day cycles in NSCLC.[2](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=06dd9d40-74fc-4409-93b1-a46be7126331) The infusion time for vinorelbine within this combination is not stated in the published trial reports.\n\nA day-1/8/15 variant exists: vinorelbine 25 mg/m² plus gemcitabine 1000 mg/m² on days 1, 8, and 15 every 28 days was tested in an NSCLC dose-finding program and showed mild toxicity with a 26.5% response rate.[9](https://pmc.ncbi.nlm.nih.gov/articles/PMC2363528/) In the same program, four day-1/8 dose levels were explored (gemcitabine/vinorelbine 1000/25, 1200/25, 1000/30, and 1200/30 mg/m²); the highest level was unfeasible because of grade 4 neutropenia.[9](https://pmc.ncbi.nlm.nih.gov/articles/PMC2363528/) No dose-modification guidance for poor performance status appears in the published reports.\n\n## Origin\n\nA phase I-II study in metastatic breast cancer patients pretreated with taxanes and/or anthracyclines is credited in the literature as the first report of the gemcitabine–vinorelbine combination.[10](https://iris.univpm.it/handle/11566/71564) That study enrolled 50 patients into its phase II part, starting from gemcitabine 800 mg/m² with vinorelbine 25 mg/m² and finding the maximum tolerated dose of gemcitabine to be 1000 mg/m², with grade 4 neutropenia in two cases at that dose level.[10](https://iris.univpm.it/handle/11566/71564) The combination was then taken to phase III in the same tumor type: the GEICAM trial recruited 252 women between 2001 and 2005 (registered as NCT00128310) and compared the doublet against vinorelbine monotherapy.[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext)\n\n## Variants\n\nSeveral distinct versions of the regimen have been tested:\n\n- Oral vinorelbine doublet. In the Norwegian phase III trial, vinorelbine 60 mg/m² orally (stated to be comparable with the commonly used intravenous dose of 25 mg/m²) plus gemcitabine 1000 mg/m² IV on days 1 and 8, for up to three 3-week cycles, versus vinorelbine plus carboplatin AUC 5.[5](https://www.nature.com/articles/bjc2012284)\n- Platinum-containing triplet. [Vinorelbine](https://www.edgepedia.org/vinorelbine) 25, gemcitabine 1000, and cisplatin 40 mg/m² on days 1 and 8 every 3 weeks in chemotherapy-naive advanced NSCLC.[11](https://www.nature.com/articles/6600658)\n- Metronomic oral vinorelbine. Daily oral dosing instead of weekly: 30 mg once daily (reducible to 20 mg) in the breast cancer NAME-trial,[12](https://link.springer.com/article/10.1007/s10549-025-07777-5) and 50 mg three times per week in the Tempo Lung NSCLC trial versus standard 60–80 mg/m² weekly dosing.[13](https://recerca.udg.edu/en/publications/metronomic-oral-vinorelbine-in-previously-untreated-advanced-non-/)\n- Every-two-week schedule. A vinorelbine–gemcitabine every-two-weeks regimen (VNR-GEMQ2W) has been evaluated in HR+/HER2- advanced breast cancer after progression on CDK4/6 inhibitors.[14](https://www.springermedicine.com/breast-cancer/breast-cancer/antitumor-activity-of-the-combination-of-vinorelbine-and-gemcita/51797232)\n\n## Applications\n\nMetastatic breast cancer. In the GEICAM phase III trial (252 women pretreated with anthracyclines and taxanes), median progression-free survival was 6.0 months with the combination versus 4.0 months with vinorelbine alone (HR 0.66, p=0.0028), but overall survival did not differ: 15.9 versus 16.4 months (HR 1.04, p=0.8046).[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) A 2011 randomized phase II trial in 141 pretreated patients compared gemcitabine plus vinorelbine, gemcitabine plus cisplatin, and gemcitabine plus capecitabine: response rates 39.0%, 47.7%, and 34.7%, and median PFS 5.7, 6.9, and 8.3 months.[15](https://www.jcancer.org/v05p0351.pdf) Pallis and colleagues' 2011 randomized phase III trial in 74 pretreated women found the doublet not superior to capecitabine monotherapy in PFS (5.4 vs 5.2 months, p=0.736).[15](https://www.jcancer.org/v05p0351.pdf)\n\nAdvanced NSCLC. In the day-1/8/15 dose-finding phase II program, 126 patients achieved one complete and 32 partial responses (26%, 95% CI 18–34) with overall median survival of 33 weeks.[9](https://pmc.ncbi.nlm.nih.gov/articles/PMC2363528/) The GEMVIN phase III trial (501 patients) found median survival of 32 weeks for the gemcitabine–vinorelbine arm versus 38 weeks for cisplatin-based doublets (HR for death 1.15, 90% CI 0.96–1.37), a nonsignificant slight advantage for cisplatin-based treatment.[6](https://ascopubs.org/doi/10.1200/JCO.2003.06.099) The Norwegian phase III trial in 444 stage IIIB/IV patients found median survival of 6.3 months for oral-vinorelbine–gemcitabine versus 7.0 months for vinorelbine–carboplatin (P=0.802), with 1-year survival of 30% versus 27%.[5](https://www.nature.com/articles/bjc2012284)\n\nPlatinum-sensitive recurrent ovarian cancer. A phase II trial in 39 patients using vinorelbine 25 mg/m² followed by gemcitabine 1000 mg/m² on days 1 and 8 every 3 weeks reported an overall response rate of 48.7% with 6 complete responses and a median response duration of 38 weeks; response depended on the platinum-free interval, 23% at 6–12 months versus 62% beyond 12 months.[7](https://ijgc.bmj.com/content/19/9/1529)\n\n## Limitations and alternatives\n\nHematologic toxicity is the most frequently reported toxicity. In the GEICAM trial, grade 3–4 neutropenia occurred in 61% of combination-arm patients versus 44% on vinorelbine alone (p=0.0074), and febrile neutropenia in 11% versus 6% (p=0.15).[3](https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045%2807%2970041-4/fulltext) The ovarian phase II trial reported grade 3/4 neutropenia in 23% of patients.[7](https://ijgc.bmj.com/content/19/9/1529) The published sources quantify only hematologic toxicity for the combination itself; frequencies of neuropathy, hepatic, and gastrointestinal toxicity of the doublet are not documented in them.\n\nAgainst platinum doublets, the combination has not won. In NSCLC, the Norwegian investigators concluded that the minor toxicity differences favoring vinorelbine–gemcitabine (grade III/IV nausea/vomiting 4% vs 12%, grade IV neutropenia 7% vs 19%) did not justify changing practice, and that platinum-based doublet chemotherapy remained the standard first-line treatment.[5](https://www.nature.com/articles/bjc2012284) The triplet with cisplatin showed better response rates (48%, median survival 13.5 months) but unacceptable toxicity: grade 4 neutropenia in 72%, febrile neutropenia in 42%, and one toxic death.[11](https://www.nature.com/articles/6600658) In first-line HER2-negative advanced breast cancer, vinorelbine–gemcitabine versus vinorelbine–cisplatin showed no significant efficacy difference (PFS HR 1.696, p=0.217), with significantly milder neutropenia (p=0.02) and nausea/vomiting (p=0.03).[16](https://ar.iiarjournals.org/content/37/10/5647) Against capecitabine monotherapy the doublet was not superior.[15](https://www.jcancer.org/v05p0351.pdf)\n\nWhat changed after 2023. Post-2023 reports include both vinorelbine-scheduling trials and new studies of the doublet itself. In the Danish NAME-trial (163 metastatic breast cancer patients, 2017–2022), metronomic oral vinorelbine was not superior to the classical days-1/8 schedule (median PFS 3.9 vs 2.3 months, P=0.236; median OS 16.6 vs 15.1 months, P=0.355, both favoring the classical arm).[12](https://link.springer.com/article/10.1007/s10549-025-07777-5) In the Tempo Lung trial (167 NSCLC patients unfit for platinum chemotherapy), metronomic oral vinorelbine significantly prolonged PFS without grade 4 toxicity (4.0 vs 2.2 months; HR 0.63, P=0.0068) and reduced grade 3–4 treatment-related adverse events (25.3% vs 54.4%), mainly through lower neutropenia (10.8% vs 42%).[13](https://recerca.udg.edu/en/publications/metronomic-oral-vinorelbine-in-previously-untreated-advanced-non-/) The VNR-GEMQ2W study illustrates repositioning of the doublet after CDK4/6 inhibitor failure in HR+/HER2- breast cancer.[14](https://www.springermedicine.com/breast-cancer/breast-cancer/antitumor-activity-of-the-combination-of-vinorelbine-and-gemcita/51797232)\n\n## References\n\n1.
