Please assess the completion status of the following clinical trial:

Trial Title: Safety, Tolerability and Immunogenicity Study of Different Vaccine Regimens of Trivalent Ad26.Mos.HIV or Tetravalent Ad26.Mos4.HIV Along With Clade C Glycoprotein (gp)140 in Healthy Human Immunodeficiency Virus (HIV)-Uninfected Adults

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE1/PHASE2
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~* Are negative for human immunodeficiency virus (HIV) infection at screening~* Is healthy on the basis of physical examination, medical history, electrocardiogram (ECG), and vital signs measurement performed at screening~* Are willing/able to adhere to the prohibitions and restrictions specified in the protocol and study procedures~* Female participants of childbearing potential must have a negative serum pregnancy test (beta human chorionic gonadotropin \[beta hCG\]) at the Screening visit, and a negative urine pregnancy test pre-dose on Day 1~* Are assessed by the clinic staff as being at low risk for HIV infection~Exclusion Criteria:~* Has chronic hepatitis B (measured by hepatitis B surface antigen test) or active hepatitis C (measured by hepatitis C virus \[HCV\] Ab test; if positive, HCV ribonucleic acid \[RNA\] PCR test will be used to confirm active versus past HCV infection), active syphilis infection, chlamydia, gonorrhea, or trichomonas . Active syphilis documented by serology unless positive serology is due to past treated infection~* Has had a thyroidectomy or active thyroid disease requiring medication during the last 12 months (not excluded: a stable thyroid supplementation)~* Has had major psychiatric illness and/or substance abuse problems during the past 12 months (including hospitalization or periods of work disability) that in the opinion of the investigator would preclude participation~* Has been in receipt of any licensed vaccine within 14 days prior to the first dose of study vaccine/placebo, plans to receive within 14 days after the first study vaccination, or plans to receive within 14 days before or after the second, third or fourth vaccination~* Is a recipient of a prophylactic or therapeutic HIV vaccine candidate at any time, or a recipient of other experimental vaccine(s) within the last 12 months prior to the Day 1 visit (Vaccination 1). For participants who received an experimental vaccine (except HIV vaccine) more than 12 months prior to the Day 1 visit (Vaccination 1), documentation of the identity of the experimental vaccine must be provided to the sponsor, who will determine eligibility on a case-by-case basis

Study Arms:
- Group 1A: Ad26.Mos.HIV (Type: EXPERIMENTAL): Participants will receive Ad26.Mos.HIV vaccine at Week 0 and 12, followed by Ad26.Mos.HIV vaccine + Clade C glycoprotein 140 vaccine containing 250 micrograms (mcg) of total protein mixed with adjuvant (aluminum phosphate) at Week 24 and 48.
- Group 1B: Placebo (Type: PLACEBO_COMPARATOR): Participants will receive placebo at Weeks 0, 12, 24 and 48.
- Group 2A: Ad26.Mos4.HIV (Type: EXPERIMENTAL): Participants will receive Ad26.Mos4.HIV vaccine at Week 0 and 12; followed by Ad26.Mos4.HIV vaccine + Clade C glycoprotein 140 vaccine containing 250 micrograms (mcg) of total protein mixed with adjuvant (aluminum phosphate) at Week 24 and 48. Participants will be included in an optional Long-term Extension (LTE) phase (3 years or 4 years Follow-up after Week 72, every 6 months visit) to assess immunogenicity and safety (serious adverse events \[SAEs\]).
- Group 2B: Placebo (Type: PLACEBO_COMPARATOR): Participants will receive placebo at Weeks 0, 12, 24 and 48.

Based on this trial design, predict the completion outcome and termination type (if applicable).
