A simple studio setup can create this look.

Most likely the key is a butterfly-style light: one main light high and close to camera axis, giving the catchlight high in the eye and keeping facial shadows controlled. The modifier could be a beauty dish or softbox; the exact choice matters less than the placement. For a longer portrait, the light may need to be fairly high and somewhat farther back.

The lack of strong background shadow is mainly achieved by placing the model well away from the background. That separation reduces visible shadow and lets you light the background independently if needed.

The bright area behind the model may be from a dedicated background light, but some respondents also noted it could be partly refined or created in post.

If you want softer shadow under the chin or lower face, add fill from below with a reflector.

One other important part of the look may not be lighting alone: the sheen on the skin suggests body oil or similar styling, which can strongly affect how highlights read in monochrome.
