Has it gotten woody? You can try cutting it back by about half and see if the new growth looks healthy.

Also check the leaves for a pest like aphids or white flies. Neem oil will help if you find pests.

Here are their cultural needs:

The closest fruiting vine like that is passion vine but the inside does not look like your photo.

I would check with your local extension agent who has probably seen this before:

It needs 2 inches of water a week and will require some pruning to keep it in check. Plus, you are barely in its hardiness range, which is zone 8 and above. You are in zone 7b.

You can heavily prune creeping fig and it will regrow. I would wait till late winter before new growth starts. Here are its cultural needs below. Yours may need more water.

Since there are other plants in the area, you will be restricted to hand pulling. If you can remove the plants for later without killing them, then you can use chemical treatment. At this time, I would recommend hand pulling until the area can be treated.

Actually, you did what I would have done. Sometimes it is easier for the plant to grow new growth than it is for it to fix dying growth. What you did was probably best.

Proper care and a careful eye will be all that you can do, unless you have not flushed the soil/had a good rain since then.
