Who this trial is looking for
This trial is looking for adults who have had surgery to remove skin cancer from their head or neck, which left a large wound that cannot be stitched closed. Participants will receive a treatment to help the wound heal better and faster.
Are You a Good Fit for This Trial?
You may be able to join if
I have had surgery to remove skin cancer from my head or neck.
My surgical wound is between 1.5-10 cm in size.
My doctor does not plan for immediate skin graft or flap.
I am over 21 years old.
I can give my consent to participate in this study.
I am willing to follow all study procedures.
I am available for the duration of the study.
You may not be able to join if
I have medical conditions that may affect my safety in this trial.
The treatment device will not fit the shape of my wound.
I currently have an infection in my wound.
I have had radiation therapy at the site of my wound.
I am allergic to porcine tissue, porcine collagen, or yeast products.
I am currently enrolled in another drug or device trial.
I am pregnant, breastfeeding, or planning to become pregnant during the trial.

Skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma lesions that develop on the head and neck are treated by Mohs surgery or wide local excision to remove all tumor cells and preserve the normal tissue. These surgical techniques may result in large defects requiring reconstruction to restore function and aesthetics. Rotational flaps and free flaps are techniques used to reconstruct large, complex defects that cannot be closed with sutures, staples, or glue. Older, frail patients are particularly vulnerable to complications from these procedures often leaving them to care for chronic wounds until a skin graft can be placed. Phenome-wide association studies (PheWAS) revealed a cohort of patients with a single nucleotide variant (SNV) in PDGFRβ having a higher incidence of chronic skin ulcers, skin grafts, and other skin and connective tissue disorders suggesting that the loss of PDGFβ signaling may impair healing following trauma. rhPDGF-BB, a recombinant human platelet derived growth factor protein-based therapy, signals through PDGFRβ to mediate inflammation, granulation, angiogenesis, and remodeling during wound healing and skin repair and is FDA cleared for diabetic neuropathic ulcers and periodontal bone and soft tissue reconstructions. These data suggest rhPDGF-BB may be a viable therapeutic strategy to augment the reconstruction of these complex defects by accelerating granulation, epithelialization, and wound closure.

Inclusion Criteria:
* Underwent surgery to completely remove skin cancer, either Mohs micrographic or wide local excision, that left a full-thickness surgical defect of the head or neck measuring between 1.5-10cm in greatest dimension with clear margins as assessed in the pathology report.
* Margins of the wound cannot be approximated or closed with stitches, sutures, staples, or glue
* Surgeon does not plan for immediate skin graft or flap
* Aged \>21 years old
* Willing and able to provide informed consent for study participation and compliance with study protocol
* Stated willingness to comply with all study procedures and availability for the duration of the study
Exclusion Criteria:
* Medical conditions that would, in the opinion of the Investigator or treating provider, compromise the safety of the individual with study participation and/or the ability of the individual to follow study protocol
* The device will not fit the contour of the base of the wound bed
* Evidence of current clinical infection as demonstrated by the invasion of bacteria into the healthy viable tissue on the periphery of the wound (colonization of wound bed due to normal flora or environment is not exclusionary)
* Prior radiation therapy at the application site
* Known allergic reactions to porcine tissue, porcine collagen, or yeast-derived products
* Currently enrolled in a drug or device trial or within 30 days of last investigational drug or device administration at baseline visit where investigational treatment (drug or device) was placed in wound bed or may potentially interact with study treatment
* Women who are pregnant, breastfeeding, or planning to become pregnant during the trial
