Looks like Pro-140 has superior suppression to UB-

Looks like Pro-140 has superior suppression to UB-421 even with a longer timeline. That hidden suppression does seem to be a myth.

UB-421 - "A total of 29 participants were enrolled, 14 in Cohort 1 and 15 in Cohort 2. Administration of UB-421 maintained virologic suppression (<20 copies per milliliter) in all the participants (94.5% of measurements at study visits 2 through 9) during analytic treatment interruption, with intermittent viral blips (range, 21 to 142 copies per milliliter) observed in 8 participants (28%)."

Pro-140 monotherapy - "11 patients have achieved full virologic suppression in the Phase 2b extension study evaluating long-term suppression of HIV replication by PRO 140 monotherapy. These patients self-administered PRO 140 weekly for 14 to 17 months. Using a very sensitive, single-copy HIV-1 RNA assay, seven of 10 patients had less than one viral copy per milliliter in their blood in the most recent month of treatment. The median of the lowest HIV RNA levels detected in these 10 patients was 0.4 viral copies per milliliter of blood."
