I can't think of any either. I will mention RAP which has been around a while and like 4DS it is pre-revenue and is a four bagger at around 10c. Whatever one thinks of efficacy, it has it's believers and will probably obtain TGA and CE Mark approval and start commercialisation soon. Similar but different is PCK which has better efficacy data IMO, is a one bagger, has less believers (I am one), has begun commercialisation but only to a small customer sub segment while it hones the product and has good upside risk from here but I must admit the recent trading not confident.
