Key Takeaway
Consider adjunctive placental-derived CAMPs for DFU closure, but note moderate certainty and wide prediction interval.

This meta-analysis examined adjunctive placental-derived cellular, acellular, and matrix-like products (CAMPs) for complete closure of diabetic foot ulcers (DFUs) at 12 weeks. It included 944 adults with active DFUs, comparing CAMPs plus standard care against standard care or a non-placental control.

Adjunctive CAMPs increased the likelihood of complete wound closure at 12 weeks, with a pooled risk ratio of 1.70 (95% CI 1.31-2.20). Absolute closure was 298/505 (59.0%) in product-treated patients versus 157/439 (35.8%) in controls.

The authors rated certainty as moderate. They noted moderate heterogeneity (I=51.9%) and a prediction interval that crossed the null (0.93-3.11), indicating the average benefit may not be reproduced by every product, population, or setting. Adverse events, serious adverse events, discontinuations, and tolerability were not reported. Funding and conflicts of interest were also not reported.

These findings support adjunctive placental-derived CAMPs as a strategy to improve 12-week closure of DFUs compared with standard care, but the wide prediction interval and unreported safety data warrant cautious interpretation.

How this fits prior evidence

This meta-analysis extends prior coverage of adjunctive strategies for diabetic foot ulcers. It aligns with the finding that Resina Draconis plus conventional therapy improves healing response, and with the network meta-analysis ranking biological debridement highest for healing, though that analysis noted limited certainty. It also contrasts with the narrative review of ADSC-Exos, which lacked reported efficacy or safety data. Unlike the dysbiosis finding, which points to microbial mechanisms, this analysis provides a pooled estimate for a specific adjunctive product class. The moderate certainty and wide prediction interval temper the result.

A review of data involving 944 adults with active diabetic foot ulcers looked at the effects of adding placental-derived products. These products can be cellular, acellular, or matrix-like. The study compared these treatments against standard care or a non-placental control to see if they helped heal wounds.

The results showed that patients who received these placental-derived products had a higher likelihood of complete wound closure at 12 weeks. Specifically, 59 percent of those using the products saw their wounds close, compared to 35.8 percent in the control group. This finding was noted with moderate certainty.

While the results are promising, the study had some limitations. Because different products and settings were involved, the results might not be the same for every patient or every specific product used. You should talk with a healthcare provider to see if these specific treatments are appropriate for your individual care plan.

What this means for you:
Adding placental-derived products to standard care may improve healing rates for diabetic foot ulcers.

Common questions

What are placental-derived products?

These are products derived from the placenta that can be cellular, acellular, or matrix-like. In this study, they were used as an addition to standard care to help treat active diabetic foot ulcers. The study found that these products increased the likelihood of wound closure at 12 weeks compared to standard care alone.

How much did these products help heal wounds?

The study found that 59 percent of patients using the placental-derived products achieved complete wound closure at 12 weeks. In comparison, only 35.8 percent of patients in the control group achieved full closure. This indicates a higher likelihood of healing when the products were added to treatment.

Is this treatment the same for everyone?

The study noted that the results might not be the same for every product, patient, or setting. Because there was a variety of products and conditions involved, the specific benefit may vary. You should consult with a medical professional to determine the best treatment for your specific situation.

Placental-derived cellular, acellular, and matrix-like products (CAMPs) are widely used as adjuncts to standard care for diabetic foot ulcers (DFUs), but trials differ in product class, comparator, and healing window. We estimated the effect of adjunctive placental-derived CAMPs on complete wound closure at a single, clinically meaningful 12-week endpoint. The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD420261399700) and reported per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020, with search reporting guided by PRISMA-S. PubMed/MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched through 21 June 2026 for randomised or quasi-randomised trials comparing a placental, amniotic, chorionic, amnion-chorion, placental membrane, or umbilical cord-derived product plus standard care against standard care or a non-placental control in adults with active DFUs. The primary outcome was complete wound closure at 12 weeks. Risk ratios (RRs) were pooled in a random-effects model (inverse-variance, restricted maximum likelihood [REML], Hartung-Knapp). Risk of bias was assessed with the Cochrane Risk of Bias 2 tool (RoB 2) for the 12-week outcome and certainty with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Prespecified sensitivity analyses included odds ratios, leave-one-out, product-class subgroups, and exclusion of high-risk-of-bias studies. Of 474 records, 14 randomised articles were retained; 9 standard-care-controlled comparisons (944 participants) provided extractable 12-week complete-closure data for the primary analysis. Complete closure occurred in 298 of 505 product-treated participants (59.0%) versus 157 of 439 controls (35.8%). Adjunctive CAMPs increased the likelihood of closure (RR 1.70, 95% confidence interval [CI] 1.31-2.20). Heterogeneity was moderate (I = 51.9%) and the prediction interval crossed the null (0.93-3.11). The effect was robust to leave-one-out analysis (RR 1.59-1.81), an odds-ratio model (odds ratio [OR] 3.36, 95% CI 1.68-6.71), and exclusion of the single high-risk-of-bias trial (RR 1.73, 95% CI 1.29-2.33). Certainty was moderate, downgraded once for inconsistency. Adjunctive placental-derived CAMPs improve 12-week complete closure of DFUs compared with standard care, with moderate certainty. The wide prediction interval indicates that the average benefit may not be reproduced by every product, population, or setting, underscoring the need for product-specific, standard-care-anchored trials and for coverage policy grounded in endpoint-specific randomised evidence.
