There are about 2656 clinical studies being (or have been) conducted in Puerto Rico. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Less invasive types of surgery may help reduce the number of side effects and improve recovery. It is not yet known which type of surgery is more effective for colon cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of laparoscopic-assisted colectomy with open colectomy in treating patients who have colon cancer.
RATIONALE: Taking part in a clinical trial may help children with cancer receive more effective treatment. PURPOSE: Determine why patients who are eligible for protocols made available through the Pediatric Oncology Group do not enroll in them, and develop strategies to increase enrollment on these clinical trials.
The purpose of this study is to see if giving tenofovir DF plus a combination of other anti-HIV drugs is safe and effective.
The purpose of this study is to compare 2 anti-HIV drug combinations.
The purpose of this study is to see if an HIV vaccine, AIDSVAX B/B, can protect adults who are at risk from becoming infected with HIV. Patients who become infected despite immunization will be studied to see if receiving the vaccine before becoming infected will help keep HIV levels (viral load) low.
To evaluate the safety and efficacy of low and high doses of lamivudine ( 3TC ) in combination with zidovudine ( AZT ) and zalcitabine ( dideoxycytidine; ddC ) in combination with AZT. PER 02/27/95 AMENDMENT: To evaluate the efficacy and safety of both blinded and open-label combination therapy.
The purpose of this study is to compare the safety and effectiveness of three anti-HIV drug combinations. The three combinations are: (1) efavirenz (DMP 266) plus indinavir; (2) DMP 266 plus zidovudine (ZDV) plus lamivudine (3TC); and (3) indinavir plus ZDV plus 3TC. This study also examines the resistance HIV may have to these drugs and if these drugs are effective over a long period of time.
To evaluate the efficacy, safety, and durability of response of SP-303 in decreasing stool weight in AIDS patients with diarrhea over 6 days of treatment.
The purpose of this study is to see if it is safe and effective to add DMP 266 to an anti-HIV treatment program of indinavir and nucleoside reverse transcriptase inhibitors (NRTIs).
To compare the durability of the viral load response following 48 weeks of treatment with 1592U89/lamivudine (3TC)/zidovudine (ZDV) versus 3TC/ZDV alone. To compare the early antiviral activity following 16 weeks treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone as demonstrated by the proportion of subjects with viral load < 400 copies/ml, plasma HIV-1 RNA profiles and CD4+ profiles. To assess the safety and tolerance following 16 and 48 weeks of treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone.
